“Someday...when I'm bigger... I wanna fight that Mario again!”

—Bowser Jr., Super Mario Sunshine

Bowser Jr., sometimes simply known as "Jr." or "Junior," is the one of the two secondary antagonists in the Super Mario franchise alongside Kamek. As his name indicates, he is the son of Bowser and serves as the prince of the Koopas, heir to the throne to be the future king. Bowser Jr. made his debut in Super Mario Sunshine, in which he is seen assuming the alter ego Shadow Mario. He has since helped his father to kidnap Princess Peach and battle Mario and Luigi in many subsequent games, as well as being playable in various spin-off games. Bowser Jr. has a strong desire to make his father proud, and Bowser's rarely seen emotional side is sometimes brought out by his interactions with his son. Bowser Jr.'s defining traits are his hyperactive and mischievous personality, his frequent use of the Junior Clown Car and the magic brush, and the bib-like bandana he wears. He bears a noticeable resemblance to his father as a baby.

History

Super Mario series

Super Mario Sunshine

“You again? Don't you ever give up?”

—Bowser Jr., Super Mario Sunshine

Screenshot from Super Mario Sunshine, when Bowser Jr. reveals his identity

Bowser Jr. is the main antagonist of Super Mario Sunshine. He is the true identity behind Shadow Mario, whom he can become through possession of a blue bandana emblazoned with a white logo resembling Mario's nose and mustache. Bowser Jr. only reveals his true identity after Mecha-Bowser had been destroyed in Pinna Park. Bowser Jr. had apparently been told by Bowser that Princess Peach was kidnapped by the "evil" Mario. Bowser Jr. escapes by converting what remains of Mecha-Bowser into a hot-air balloon and flying it to Corona Mountain with Princess Peach. Not counting his Shadow Mario disguise, Bowser Jr. is next seen at the end of Corona Mountain with Bowser, relaxing in the hot tub with him. Bowser Jr. assists Bowser in the battle by firing Bullet Bills at Mario. After both are defeated in battle, Bowser Jr. and his father are on the flipped hot tub, floating near Isle Delfino. Bowser Jr. is told by Bowser remorsefully that Peach is not his mother, to which Bowser Jr. similarly admits that he had figured it out by the time. Bowser Jr. makes Bowser proud when he says that he plans to fight Mario again some day.

New Super Mario Bros.

Bowser Jr. appears in New Super Mario Bros. He co-stars with Bowser as the main antagonists. The events of the game begin with Bowser Jr. kidnapping Peach, after Mario is distracted by a lightning cloud that hit Peach's Castle. Bowser Jr. is the boss of every tower: If his bandana is hanging loose, Bowser Jr. jumps and charges at Mario, but if he wears the bandana over his mouth, Bowser Jr. throws a Koopa Shell at the player character and ducks into his shell whenever close to him, though a Koopa Shell can leave him open to attack. In Worlds 2, 3, 5 and 8, Bowser Jr. jumps high after two hits. In each battle, Bowser Jr. is defeated after being stomped three times, if he is not in his shell, which inflicts damage. Fireballs and Shell Dash maneuvers can damage Bowser Jr. as well. Bowser Jr. is last battled in World 8-Bowser's Castle, as the final bosses, this time with Bowser, whom he throws into a pot filled with some form of magic potion, restoring Bowser from his skeletal form and making him both larger and stronger than before. Both Bowser Jr. and Bowser are defeated by Mario, and Peach is rescued. In a scene of the ending, Bowser Jr. is dragging an unconscious Bowser, then faces the screen to growl before continuing to drag Bowser.

Super Mario Galaxy

“You just don't give up! Fine, then. I guess I'll just have to whup you myself! You want this Grand Star so bad? You're gonna have to take it from me!”

—Bowser Jr., Super Mario Galaxy

Artwork from Super Mario Galaxy, largely using his design from Super Mario Sunshine

Bowser Jr. is a recurring boss within Super Mario Galaxy. He is fought three times, guarding a Grand Star each time. Bowser Jr. is first encountered in Bowser Jr.'s Robot Reactor, where he summons Megaleg to attack Mario. He later appears in Bowser Jr.'s Airship Armada, using his small personal airship. Bowser Jr. is again seen in Bowser Jr.'s Lava Reactor, where he summons a more powerful King Kaliente to attack Mario. Bowser Jr. is later encountered in Bowser's Galaxy Reactor, keeping Peach on his airship, and launches cannonballs to destroy the steps that Mario is going up. Bowser Jr. spectates the final battle while keeping Peach by his side. Bowser Jr. falls out of his airship after Bowser is defeated and into his sun. Bowser Jr. is last seen dancing back in the Mushroom Kingdom on an airship in the water with an Octoomba.

Bowser Jr.'s theme opens similarly to themes that play when Peach's castle is being lifted and during the final phase of the last fight against Bowser, but heavily sped up.

New Super Mario Bros. Wii

“I ordered my minions to stuff every annoying Toad they catch into a ? Block. Hah! If you want to save 'em, come alone. You won't get help from your friends!”

—Bowser Jr., New Super Mario Bros. Wii

Bowser Jr., in his personal Junior Clown Car, in New Super Mario Bros. Wii.

Bowser Jr. is a recurring boss within New Super Mario Bros. Wii. The game starts with Bowser Jr. and the Koopalings arriving at Princess Peach's castle for her birthday celebration, hiding inside of a birthday cake. Bowser Jr. and the Koopalings emerge from the cake to suddenly kidnap Peach and load her onto the airship, an infiltration method that they had planned beforehand. Bowser Jr. and the Koopalings make a flight to Bowser's Castle via the airship while Mario, Luigi, and the two Toads follow them, beginning their journey to rescue Peach. After Mario and his friends complete World 1-3 for the first time, a Toad runs to them and inform them that Bowser Jr. has sent them a letter. In the letter, Bowser Jr. wrote that he ordered his minions to capture and trap any Toad into a ? Block. Bowser Jr. is fought three times, each taking place on an airship and requiring three hits to defeat him. In the first battle, Bowser Jr. uses his own flying vehicle to move around in. Bowser Jr. takes damage from either a Propeller Block being thrown at him or the player character using one to reach Bowser Jr. and stomp him. Bowser Jr. can breathe fireballs to the ground, setting it ablaze on contact and creating another obstacle for Mario. In the second battle, Bowser Jr. uses his heavily damaged vehicle (attached with doubler plate) to battle, while the player character uses a Remote-Controlled Clown Car: Bowser Jr. can be damaged from hitting an electric rail or from being stomped, this time by Propeller Mario. The third battle starts with Bowser Jr.'s vehicle being knocked over from the player character entering the room with a Ground Pound. Bowser Jr. kicks his broken vehicle aside to use the Koopa Clown Car instead, from which he attacks by dropping large spiked bombs on the field with its mouth cannon. Bowser Jr. takes damage from a spiked bomb being launched up to him, damaging the Koopa Clown Car in the process. Bowser Jr. can now fire more than one fireball in a row, in addition to homing in on Mario, and they create blazing obstacles on the floor. Bowser Jr. last appears in the ending, commanding Larry to help the other Koopalings help Bowser off his shell. He eventually gets hoisted up, though Bowser's Castle starts collapsing on them.

Super Mario Galaxy 2

“ Ohhhhh, Gobblegut! Dinner's on! Don't forget to protect your bellyache bulges!”

—Bowser Jr., Super Mario Galaxy 2

Bowser Jr. appears in Super Mario Galaxy 2. He is the secondary antagonist. Bowser Jr. is first encountered in Bowser Jr.'s Fiery Flotilla briefly, inside of his robot cockpit, and he summons Gobblegut to battle Mario. Bowser Jr. is later fought while piloting his Megahammer in Bowser Jr.'s Fearsome Fleet. Bowser Jr. uses his Boomsday Machine in Bowser Jr.'s Boom Bunker while fighting Mario, using the machine to attack with spinning Fire Bars and launch balls of electricity. Once Bowser Jr. is defeated, his Boomsday Machine explodes, launching Bowser Jr. into space.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe

Artwork from New Super Mario Bros. U, showing Bowser Jr. in his Junior Clown Car, which is equipped with boxing gloves.

Bowser Jr. is the secondary antagonist of New Super Mario Bros. U, New Super Luigi U, and their port. Bowser Jr. pilots the flagship, and ambushes the player at the beginning of Soda Jungle, in The Mighty Cannonship (All Aboard! in New Super Luigi U), where he uses his Clown Car as a submarine underwater, in which the player must guide the Targeting Teds launched by Bowser Jr. With every hit, he summons three Torpedo Teds from the left and right or four from the ceiling and the floor. The course ends with the water draining out and a mechanical hand sweeping across the ground before Mario jumps off of the airship. In Boarding the Airship (Bowser Jr. Showdown in New Super Luigi U), at the end of Meringue Clouds, Bowser Jr. uses his Junior Clown Car, equipped with boxing gloves, which he uses to destroy the blocks the player is standing on. Bowser Jr. periodically throws Bob-ombs, which can be used against him. After the boss fight, Bowser Jr. tries to crush the player character on the airship, but it accidentally destroys the airship instead. Bowser Jr. reappears in The Final Battle, where he slams his Junior Clown Car onto platforms to hinder the player's progress during the main course. Bowser Jr. later convinces Magikoopa to enlarge Bowser, after the latter is first defeated. Bowser Jr. attacks in the final boss fight by tossing Bob-ombs and slamming into the ground. The Junior Clown Car can be hijacked from Bowser Jr. and used to damage the enlarged Bowser. While on the ground, Bowser Jr. shoots fireballs and occasionally spins inside of his shell. If stomped while on the ground, Bowser Jr. can be picked up and thrown at Bowser to damage him. Bowser Jr. is last seen in the ending, struggling to carry Bowser and the Koopalings out of the Mushroom Kingdom.

Super Mario Maker / Super Mario Maker for Nintendo 3DS

Screenshot from Super Mario Maker, showing Mario facing Bowser Jr. in the Super Mario Bros. 3 style

Bowser Jr. is a usable enemy in Super Mario Maker and its port. He can be placed by shaking Bowser. He behaves similarly to the Koopalings in Super Mario Bros. 3, doing shell spins, shooting fireballs, and performing ground pounds capable of stunning the player character while they are on the ground. Only up to three Bowser Jrs. can be placed in a course. Bowser Jr. can be defeated by stomping him three times, throwing enemies at him, or from 15 fireballs (30 if giant-sized). Besides fluttering, Bowser Jr. can throw hammers and survive falling into a pit if he has a pair of wings. Bowser Jr. commonly throws two Koopa Shells at the player character while inside of the the Junior Clown Car; the size of the shells are relative to whether Bowser Jr. is regular-sized or giant. Bowser Jr.'s music block instrument is the saxophone.

Bowser Jr. is an unlockable Mystery Mushroom transformation in the original version only. He can be unlocked by clearing the 100 Mario challenge on normal or harder or by scanning a Bowser Jr. amiibo. Bowser Jr.'s palette is based on Bowser's original sprite in Super Mario Bros. while using his Koopa Clown Car. The "blunder" sound effect plays the sound for when Bowser Jr. is "hit" in the New Super Mario Bros. subseries. The Bowser Jr. costume is inside of a bubble in underwater settings only.

Super Mario Maker 2

Bowser Jr. is a placeable enemy in Super Mario Maker 2. He is unavailable in the Super Mario 3D World style but remains usable in the other styles. Bowser Jr. is functionally similar as in the previous game, but he was changed to becoming a separate course element. In story mode, Bowser Jr. is suggested to be Name Withheld by Request, whose course descriptions mentions attempting to "recreate evil courses" by "watching his dad."

Super Mario 3D World + Bowser's Fury

“Mario! Dad is out of control! I don't know what happened... I tried to help him, but he's too big and mad. I can't change Dad back by myself... I'd never ask you for help. Never EVER! But I'll do anything to save Papa. So... help me, Mario.”

—Bowser Jr., Super Mario 3D World + Bowser's Fury

Artwork from Bowser's Fury, showing Bowser Jr. and Mario teamed up

Screenshot from Bowser's Fury, showing Bowser Jr. in his Cat form

Bowser Jr. is both an ally and a playable character in the Bowser's Fury mode of Super Mario 3D World + Bowser's Fury. The events begin with Bowser Jr. teleporting Mario into Lake Lapcat using the magical paint from his brush, before explaining Bowser's plight to him. The two go on a journey to rescue Bowser. It is eventually revealed that he was essentially the reason why the events of the game happened, as he accidently painted his dad while the latter was asleep, which infuriated the latter to such an extent that he became Fury Bowser. In gameplay, Bowser Jr. flies around in his Junior Clown Car and wields his magic brush, which he can use to defeat enemies or bring power-ups out of ?-marked walls. He can also be sent out to grab distant collectibles or inspect faraway spots by means of a special cursor. In single-player mode, he is AI-controlled (with the player choosing how much assistance he provides), although a second player can optionally control him as well. Upon 100% completion, Bowser Jr. turns into a cat-like form similar to Meowser, although this is purely cosmetic. Whenever Mario takes damage while Bowser Jr. is not doing anything, the latter giggles at him. Should Mario get hit while in small form, however, Bowser Jr. gasps in distress instead. If the player scans the Bowser Jr. amiibo, Bowser Jr. produces a red shockwave identical to that of POW Blocks that defeats any nearby enemies and destroys most objects.

Super Mario Bros. Wonder

Bowser's Rage Stage. Bowser Jr. attacks by spinning back and forth in his shell, and by spitting fireballs. After taking damage once, Bowser Jr. becomes Wonder Bowser Jr. and causes several different Wonder Effects to occur.

In the handheld version, Bowser Jr. is unlocked by completing Classic on Intensity 6.0 or higher as Bowser or by playing 100 Smash matches, then defeating him on 3D Land. Bowser Jr. fights in his Junior Clown Car, using a variety of built-in weapons to attack. Bowser Jr. takes 1.15× more damage than normal if his normal body is hit, whilst hitting the Junior Clown Car reduces this to 0.88×. Some of his voice clips are reused from Mario Kart Wii. Bowser Jr.'s weight is also above average. All of Bowser Jr.'s attacks have disjointed hitboxes, unlike the other fighters. Bowser Jr. dashes slower than most other characters, but he has decent mobility while in the air. Bowser Jr.'s neutral special move is Clown Cannon, which fires a cannonball from a cannon in the mouth of the clown car. His side special move is Clown Kart Dash, which turns the Junior Clown Car into a kart that speeds forward. His down special move is Mechakoopa, which deploys a Mechakoopa. His up special move is Abandon Ship, where Bowser Jr. is ejected from the Junior Clown Car, which explodes shortly afterward. His Final Smash is Shadow Mario Paint, in which Bowser Jr. turns into Shadow Mario and paints a giant "X" across the screen that damages opponents. Bowser Jr.'s seven alternate costumes are the seven Koopalings, each with their own voices and having different faces for their variants of the Junior Clown Car. Because of this, Bowser Jr. is the only fighter in Super Smash Bros. for Nintendo 3DS / Wii U whose alternate trophy does not utilize any of his alternate palettes. Bowser Jr. is the only fighter who can utilize the Drill equipment, increasing his attack power, and he can use the Shell and Dash Mushroom equipment to boost his defense and speed, respectively.

Bowser Jr. in Super Smash Bros. Ultimate

Bowser Jr. is an unlockable playable character in Super Smash Bros. Ultimate. He retains the Koopalings as his seven alternate costumes. Bowser Jr.'s neutral special move was changed to end with an uppercut, whilst several of his attacks have decreased range. Bowser Jr. was given a stronger down throw. Bowser Jr.'s down tilt now enables him to eat food items. His forward smash is called Smash Twin Drills. Bowser's up tilt has a sourspot that inflicts less damage, Bowser Jr.'s down tilt, dash attack, and neutral aerial all deal more damage. Bowser Jr. benefits from universal changes, including increased mobility, reduced short hop timing, lessened landing lag in his aerial attacks, the reintroduction of directional air dodges, and the abilities to use any ground attack out of a run, as well as using aerial attacks on ladders. The Junior Clown Car's hitbox is prioritized over Bowser Jr.'s, protecting him from being affected by potential additional damage to him. Bowser Jr.'s special attacks also receive a mixture of buffs and nerfs to rebalance them.

Bowser Jr. is seen in Ken's and Incineroar's debut trailer nearing the end, where he, King K. Rool, and Villager await to challenge Incineroar for the bout after it beat Ken, much to its chagrin. Bowser Jr. briefly appears in the reveal trailer for Sephiroth.

Bowser Jr.'s Classic Mode route involves him battling fighters who are parental figures/children of other characters or who fight alongside other loved ones or close partners. Bowser Jr.'s Classic Mode route's name is "Mama Peach, Where Are You?," alluding to him calling Peach "Mama" in Super Mario Sunshine and several other games. Bowser Jr. engages in the battles in the following order:

1. Rosalina on Mario Galaxy
2. Lucina and Chrom on Arena Ferox
3. Daisy and Luigi on Mushroom Kingdom U
4. Zelda on Hyrule Castle
5. A horde battle featuring two Mii Brawlers, two Mii Gunners, and two Mii Swordfighters on Peach's Castle
6. Mario and Peach on Delfino Plaza
7. A boss fight against Master Hand (and Crazy Hand on intensity 7.0 or higher) at Final Destination

Paper Mario: Sticker Star

“Oh nooooo, the babies ran away! Looks like there's no need for Dad to come out. I AM NOW THE FINAL BOSS!”

—Bowser Jr., Paper Mario: Sticker Star

Bowser Jr. in his Junior Clown Car

Bowser Jr. appears in Paper Mario: Sticker Star as a mini-boss. He is first seen in Warm Fuzzy Plains, where he is chasing a Toad to obtain a rare sticker. During this battle, Bowser Jr. attacks by ramming into Mario with his Junior Clown Car, which allows him to avoid hammer attacks. Additionally, whenever Mario attacks him, he recovers all his HP. The only way to defeat him is to use the Scissors sticker obtained right before the battle. When Mario defeats him, he uses the paperization ability to take the bridge out, crumple it up, and throw it away to block Mario's way, and then flies away.

He is next seen in World 4. If the player takes the boat back to Decalburg, he attacks Mario on the boat. This time, he uses the healing technique and Junior Clown Car ram from the previous battle, but may also pull 1 to 3 Bob-ombs out of the car and toss them at Mario. Each Bob-omb deals 6 damage, but Mario can hit Jr. while he is holding them to damage Jr. However, if Mario jumps on Bowser Jr. while he is holding Bob-ombs, Mario loses 10 HP for each Bob-omb Bowser Jr. is holding. When defeated, Bowser Jr. returns to his dad.

When Mario attempts to reach Bowser's Sky Castle via Flutter, Bowser Jr.'s airship blasts a Banzai Bill at Mario. He informs Mario that he no longer cares about rare stickers, but rather exacting revenge on Mario. He is last fought in his airship, where he implements a protective shield on his Junior Clown Car; this shield lasts until he has only 100 HP left. Additionally, he attacks by barraging the player with fireballs, spiked balls, and ramming Mario with his clown car, in rapid succession. Mario can defeat him most easily by using a Tail sticker to block the fireballs, repel his ramming attack, and return his spiked balls, the latter doing 50 damage per successful counterattack. Once Mario defeats him, Bowser Jr. is sent flying off the ship, not to be seen again until later. Although dialogue from both Kersti and Bowser Jr. himself implied that he perished as a result of the battle, the ending credits revealed that he had survived, where he is seen with his dad riding on their own parade float.

Paper Mario: The Origami King

“I just came here to help Dad, but the next thing I knew I was all cut up into pieces. And what's he doing here? Are we about to fight? Because I'm always ready. Let's go!”

—Bowser Jr., Paper Mario: The Origami King

Artwork from Paper Mario: The Origami King

Bowser Jr. is an ally in Paper Mario: The Origami King. When Mario, Olivia, and Kamek are about to enter Bowser's Castle—which has crash-landed into Shangri-Spa's banquet hall and where a green streamer is leading to—Boss Sumo Bro attacks them from a high-up cloud. As Kamek ponders how to get up to the cloud, Bowser Jr. appears in his Junior Clown Car, aiming for the castle in an attempt to rescue his father, but he is then sliced into pieces by Scissors. After Kamek picks up the dismembered pieces of Bowser Jr., he, Mario, and Olivia hurry to Spring of Purification, where Bowser Jr. is pieced back together, but is creased, wrinkled, and smudged to assist the trio. With Bowser Jr. riding on Kamek's back, Mario, Olivia, and Kamek take him to other springs around Shangri-Spa to revitalize him further. However, upon soaking in the Spring of Jungle Mist for too long, Bowser Jr. is drained of his colors, losing his energy in the process. After visiting all springs and obtaining the Spring of Rainbows - VIP, Mario, Olivia, and Kamek then take Bowser Jr. to the Spring of Rainbows where he is restored of his color and energy.

After returning to his normal self and before adventuring further into Bowser's Castle, Bowser Jr. can aid Mario in battle by using Tantrum, attacking by ramming through enemies in a straight line in his Junior Clown Car and dealing 50 damage (75 if the Ally Tambourine is equipped). However, Bowser Jr. may bump into the first enemy in the line, falling out of his Junior Clown Car, and dealing no damage.

In Bowser's Castle, Bowser Jr. is determined to rescue his father who is held captive. While the normal Koopa Troop minions combat the Folded Soldiers, Bowser Jr. repeatedly attempts to push through the locked door in the entrance hall. After all the minions suddenly vanish, Bowser Jr. is pulled through, but is then sliced into pieces again by Scissors, who has sliced the other minions as well. After Mario defeats Scissors in a near-death battle, Bowser Jr. is restored to normal, along with the other minions. Mario then assists Bowser Jr. and Kamek in freeing Bowser after clearing the green streamer.

When Mario, Bowser, and the rest of the minions board an airship to fly to Peach's Castle, Bowser Jr. flies alongside in his Junior Clown Car and partakes in a battle against a fleet of paper planes dispatched by King Olly. However, a particularly large plane slams into the airship, causing it to crash-land into Hotfoot Crater. As Bowser Jr. has lost his Junior Clown Car in the event, he has to proceed on foot with Kamek (who has lost his broomstick), Mario, and Olivia. As they make their way out of the volcano, they find a horde of small Paper Macho Goombas, who dropped into the volcano, in hot pursuit. After Kamek creates clones of himself in an attempt to hold back the horde, Bowser Jr. witnesses the remains of the airship completely sink into the lava, to his dismay. But then, the horde breaks through Kamek and his clones, so Bowser Jr. stomps on a loose rock in their path to create a ditch to take on the horde himself, allowing Mario to keep going. Unfortunately, Bowser Jr. gets overwhelmed by the horde, to Bowser's horror, so Bowser then blasts a fireball at a stalactite that blocks off the horde from Mario.

After Mario, Olivia, and Bowser defeat King Olly, Bowser Jr. is revealed to have survived the ordeal, as he and Kamek assist Luigi in escorting the Origami Craftsman to Origami Castle, where they witness the Origami Craftsman help Olivia complete the Thousand Cranes Technique that King Olly started. After Origami Castle is transformed back to Peach's Castle, Bowser Jr. is later seen attending the Origami Festival. Bowser earlier implied Bowser Jr.'s survival by mentioning Mario and Olivia about his parenting philosophy of letting kids take chances.

During the credits, one of the photos shows Bowser Jr. soaking in the Spring of Sanctuary with Bowser and a handful of Koopa Troop minions.

Mario & Luigi series

Mario & Luigi: Dream Team

Bowser Jr. in Mario & Luigi: Dream Team.

Bowser Jr. appears in Mario & Luigi: Dream Team as the final boss of the Battle Ring, where he is faced after defeating all the other X Bosses in the Battle Medley. He rides in his Koopa Clown Car, now officially named the Junior Clown Car. The battle is similar to Bowser X from Mario & Luigi: Bowser's Inside Story. Bowser Jr. is the only non-X boss in the Battle Ring.

His battle has a unique setting: a castle courtyard environment with Bowser Jr. banners. It is night, and fireworks burst in the background. Multiple enemies, such as Shy Guys, Koopa Troopas, and Goombas, are watching the battle from the stands.

Bowser Jr. has a unique animation where he flies from the foreground, breathes fire into the screen, then comes down to the Bros. level for the fight to start. Luigi is visibly shocked to see him when he appears.

While in his Junior Clown Car, Bowser Jr. can only be harmed by attacks from above such as jumping or Zee Egg; any attacks that hit him from the side such as Bomb Derby or Slingsniper are completely ineffective as he hides within his Clown Car during all of the Bros. actions. If a Bros. Attack is used, even if it has no effect, Bowser Jr. tickles the user with his magic brush and steals the attack. Stolen attacks do not appear in the menu, so they can no longer be used. Attacking Bowser Jr. hard enough may cause him to drop the attacks, returning them to the menu. Bowser Jr. has four attacks.

One attack starts by throwing a spiked ball at Mario or Luigi. This can be blocked by the hammer, but the ball bounces to the other brother. This forces the Bros. to deflect the ball between them with the hammer. Eventually Bowser Jr. attempts to ram one of them. Deflecting Bowser Jr. knocks him back while flipping the Junior Clown Car upside down. Bowser Jr. follows up by walking to one of the brothers while underneath the Clown Car. Once he arrives, he will lift up the car then breathe fire at that brother, hitting multiple times. This can be prevented by hammering him the instant he lifts the Clown Car up while facing the Bros. The Clown Car blocks any preemptive swings, as well as any done if Bowser Jr. faces away from the Bros. as a fake out.

Another attack has Bowser Jr. toss a Bob-omb on the ground. It runs in a circle, passing through Mario and Luigi and exploding on contact. They can jump to avoid the Bob-omb, while Bowser. Jr complicates the pattern by shooting a fireball the brother who is not being approached by the Bob-omb at regular intervals. Eventually the Bob-omb explodes on its own, ending the attack. The attack ends early if the Bob-omb hits Mario or Luigi.

His third attack summons two Shy Guys holding a string of fire similar to a Fire Bar. The Bros. must jump over the fire in a similar manner to the Border Jump minigame from Mario & Luigi: Superstar Saga. The Shy Guys stare at both Bros. before randomly appearing at the top or bottom of the screen and go the opposite way. The fire is extinguished if it hits a character, but the fire ignites soon after and the attack will continue. Once the Shy Guys stop between Mario and Luigi, they begin to spin the fire it like a helicopter blade that all characters must jump over; the attack occasionally gets delayed by the Shy Guys stumbling, and ends when Bowser Jr. or one of the Bros. is hit. If Bowser Jr. is hit, he angrily knocks the Shy Guys into the background. They loop around into the foreground, with their trajectory passing through the Bros. Mario and Luigi must jump over the Shy Guys as they land.

Finally, Bowser Jr. calls a circle of nine Shy Guys with presents. He and the Bros. take turns opening the gifts by hitting them with hammers. The presents can contain a Bob-omb, an item, any stolen Bros. Attacks, or nothing. Opening the Bob-omb inflicts damage and concludes the attack early. The player is able to tell which Shy Guy has the Bob-omb by observing when Bowser Jr. chooses, as that Shy Guy starts to sweat when Bowser Jr. is over him. If all other presents have been opened, Bowser Jr. is forced to open the present with the Bob-omb, causing him to take damage.

When damaged enough, Bowser Jr. jumps out of his Junior Clown Car, leaving the Car floating. While out of his Clown Car, Bowser Jr. can be damaged by any attack. He can return to the Clown Car after a certain number of turns, but the player has a optional opportunity. Mario or Luigi can jump inside the Junior Clown Car with their jump attack. The other brother hops in, and the two chase Bowser Jr. into the foreground with it. The Junior Clown Car moves left and right by tilting the 3DS. Each brother has an aiming reticle, which stays relative to the Junior Clown Car: Mario is the right reticle and Luigi is the left. Pressing their corresponding button has that brother throw an object at Bowser Jr. Between throws, the Bros. look through the Clown Car to find the next object. After the attack, the Mario Brothers jump out, leaving the malfunctioning Junior Clown Car to crash into Jr. Afterward, the crashed Clown Car stays in the background, and Monty Moles appear to repair it over the course of several turns. Throwing a Taunt Ball obtained from Jr.'s present attack at the Monty Moles increases the amount of time it takes for them to repair it.

Mario & Luigi: Paper Jam

“Gahaha! Come and get us... if you can!”

—Bowser Jr., Mario & Luigi: Paper Jam

Artwork of Bowser Jr. and Paper Bowser Jr.

Bowser Jr. returns in Mario & Luigi: Paper Jam, where he has a role in the story, unlike in Dream Team where he was an optional boss. He is also accompanied by his paper counterpart. The two Juniors are the secondary antagonists of the game alongside Kamek and Paper Kamek.

Bowser Jr. first appears alongside his paper counterpart in Bowser's Castle, where they meet each other for the first time. Unlike his father and Kamek, Bowser Jr. and Paper Bowser Jr. quickly resolve their argument and become friends. The two Bowser Jrs. are later tasked to watch the two princesses as the two Bowsers and Kameks line up their troops. As they stand guard to watch the princesses, they both get the idea of destroying the book to prevent Paper Bowser Jr. from going home so that they can both no longer feel bored. In Doop Doop Dunes, as Roy is about to take the book to throw in the trash, Bowser Jr. and his paper counterpart show up and stop him. After a brief discussion with Roy, Bowser Jr. takes the book from the ground and heads back to Bowser's Castle.

Back at Bowser's Castle, the Bowser Jrs. go to throw the book in the trash before changing their minds, instead choosing to keep it. The Bowser Jrs. then attempt to show the book to their fathers, but the Bowsers tell them that they are busy and to keep watching the princesses. The two Bowser Jrs. then start to complain and jump around the room saying they don't want to be on guard duty. Kamek suggests to Bowser to take the Juniors to the Mount Brrr villa, which the Juniors agree to do as they are promised a special surprise. They take the princesses along with them.

At the Mount Brrr villa, as Bowser Jr. is impressed at the area, Paper Bowser Jr. appears and tell him to checkout a papercraft of themselves. Later on, as Mario & co. climb up the mountain, they notice Bowser Jr. at a higher level, who enjoys the high area before making himself leave from Paper Bowser Jr. playing with their new Papercraft. When the Mario gang reach the top of Mount Brrr, they encounter the two Bowser Jr.s with their new papercraft. The Kameks advice the Juniors to leave the area but the Juniors want to stay and play with their new papercraft. After Toadette sends the newly built Papercraft Peach to the Mario gang, they battle the Bowser Jrs. in a papercraft battle. After Mario & co. destroy the Papercraft Bowser Jr., the Juniors along with the Kamek duo retreat to Bowser's Castle, but they drop a red medallion along the way. The two are later seen guarding the Princesses again. While the regular Bowser Jr. sleeps, the two Peachs are successfully able to trick Paper Bowser Jr. with a decoy and escape their cage.

They soon realize they have been tricked and recapture the two Peachs before they can reunite with the Marios. Bowser Jr. and Paper Bowser Jr. deduce the Mario gang is attempting to steal back both the Peachs and the book, and taunt the Mario gang by showing it off, which they admit was not a smart move. They then run off in different directions until the trio sneaks up and captures them both. They give the group a fake book and then retreat back to where they were first encountered. Commenting that fighting is more fun than running anyway, the two engage the Mario gang in battle.

Reflecting their friendship throughout the game, the pair fight as the Mario Bros. would and almost always attack in tandem with each other. When one of their HP is getting low, the other can heal them with a Mushroom. Furthermore, whenever the one of the trio attacks, the can hide inside their Junior Clown Cars, completely protecting themselves from everything except aerial attacks. Their first move involves each of them pointing at a specific Bro, indicating to the player who has been targeted. They then fly back a large distance in their Clown Cars and start to ram at their victims, changing positions to throw off the player (if either one suddenly jumps out of their Car, it drifts towards Paper Mario). Successfully countering the attacks causes the two to fall on the ground in front of the heroes, allowing them to hit the Jrs. with additional hammer strikes before they get back into their Cars. Bowser Jr. then challenges the Marios to a flying contest by folding their paper partners into airplanes. Paper Mario must then race Paper Junior by pressing just as he is about to hit the ground in order to gain more distance and height. If Paper Mario manages to win, spiked iron balls drop from above the screen and smash the Juniors on their heads. Likewise, if Paper Bowser Jr. flies further, the iron balls fall on the Bros., inflicting massive damage. Another attack they have is to order Shy Guys to cover the group in barrels as they run away from the spoiled children. Meanwhile, the Jrs. take turns shooting fireballs at them, who must jump to dodge them (The player can also jump to remember which Bro is which, or look for Paper Mario's feet). Failure to avoid the fireballs results in the hit Bros. falling down, while dodging their onslaught allows the team members that were not hit throwing off their barrels, which hit the pair. Bowser Jr. can sometimes fly into the background and lift a gargantuan cannonball with his insignia, throwing it at the heroes who need to use the Trampoline Guard to send it back at him. Paper Junior can also lie in wait on the floor during the attack, and the trio must sidestep him in order to avoid getting ambushed and extremely hurt by the cannonball. After several successful bounces, the cannonball falls onto Junior, delivering a solid blow. Once a single Junior is taken out, the gang must defeat the other as quickly as possible, or he revive his partner with a 1-Up Mushroom. If they manage to accomplish that, they win the battle.

As the Mario gang celebrate their victory, the two Bowser Jrs. lay heavily injured on the floor. They think back on all of the fun they had together and their dream of staying friends forever, as well as their ill-fated decision not to destroy the book when they had the chance. Before the Mario gang are able to recover the book from them, Bowser and Paper Bowser appear and complain that the princesses have escaped under their sons' watch. When the two realize that their sons can barely move or speak because of their injuries fighting Mario, the Bowsers become enraged and cradle them in their arms. As the Bowsers show off the modifications to their castle, the two Bowser Jrs. feebly try to tell their dads how important it is that Mario does not get the book, but neither listens to them at first.

Neither are seen for the rest of the game, although presumably Paper Bowser Jr. is forced to return to his own world after the trio retrieve the book at the end of the game.

—Bowser Jr., Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

Artwork of Bowser Jr. from Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.

Ranged Bowser Jr.

Bowser Jr. appears in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey as the main protagonist, in a game mode starring him on an adventure, similar to Minion Quest: The Search for Bowser from the remake of Mario & Luigi: Superstar Saga. In the story, he attempts to find the cures for the blorbs (as it was also impacting Bowser's kingdom), hoping to impress his father in the process. However, his more selfish traits end up causing a lot of trouble for his allies, notably the Koopalings. Later in the game, Bowser Jr. can be reclassed as any of the three minion types; his Melee form is his default form and has him run into his enemies, his ranged form is unlocked after Morton gives him his magic brush in Dimble Wood and has him fire blobs of paint from the paintbrush, and his flying form is unlocked after he finds Iggy's Clown Car in Cavi Cape after Iggy went missing and has him fly into his foes with his Junior Clown Car, which he had converted Iggy's into.

In the beginning of the game, he spars with Captain Goomba, although because Bowser Jr. cannot count properly, he keeps increasing the amount of wins he needs to be satisfied. After Roy and Wendy are given the recipe for Skeletone Formula:D by the Best Fitness Friends, Bowser Jr. decides to look for the ingredients himself to impress his father. To test his strength, Ludwig dispatches Captain Goomba and the other captains to fight him, eventually alongside King Bob-omb, and after Bowser Jr. passes, he and the Koopalings (with the exception of Lemmy, who stays behind to guard Bowser's Castle) go to Dimble Wood to find the Giga Carrot. Morton also gives Bowser Jr. a Charred Spicy Drumstick, although he says he will eat it later.

During the search for the Giga Carrot, the Koopalings leave Bowser Jr. one by one. Ludwig gets worried someone is watching them, Roy gets too fed up with Bowser Jr.'s bad attitude, and Wendy and Larry leave to investigate Bowser's Castle after hearing Fawful had attacked it. By the time the Giga-Carrot is found, Morton and Iggy are the only Koopalings left, and Kamek joins them.

However, while searching for an Omega Onion in Cavi Cape, Bowser Jr. fires Iggy because he finds him too annoying, and does not care what happens to him, even after finding his Clown Car lying around.

After the Skeletone Formula:D had been created, Bowser Jr., Morton, and Kamek travel back to Bowser's Castle when Kaley and Dieter steal the Skeletone and mix it with a Malodorous Fibbian to create Malatone Formula:X. Bowser Jr. worries he is not be able to impress Bowser now, but Morton is fed the Malatone and becomes brainwashed by its effects. The Malatone-infected Morton knocks out Bowser Jr. and Kamek, and throws them into Blubble Lake.

The two wash ashore on Plack Beach. Kamek reminds Bowser Jr. of his off-putting behavior, and that the loyalty of minions comes from respecting them just as they respect their leader. After Bowser Jr. sorrowfully comes to understand this once he is all alone as he eats the Charred Spicy Drumstick Morton gave him earlier, feeling remorseful about his behavior to the Koopalings, and realizing he cannot defeat the Best Fitness Friends by himself, he promises Kamek he will become more mature. After walking around the beach, they find Iggy, although he is amnesiac and thinks he is Kuzzle's long-lost grandson Charlie. Bowser Jr. fights him to give him the "Shock Treatment". Afterwards, Iggy rejoins Bowser Jr., although his memory is still hazy.

They follow Kaley and Beef into Dimble Wood, after hearing they were looking for Ludwig. When confronting them, it turns out that "Beef" was actually Ludwig in disguise and reveals everything about the BFF's plans to Bowser Jr. They defeat Kaley in battle and force her to retreat, and Ludwig presents an antidote to Malatone Formula:X called the RenewaLeaf.

They return to Blubble Lake to track down the other Koopaling. The Koopa Paratroopa Trio inform the group that Larry and Lemmy were sighted in the area. During their search they encounter Mario and Luigi. Just as they are about to fight, Starlow stops them, stating they need to find the Star Cures as quicky as possible. She then assures Bowser Jr. that his father is working very hard too. Not long later, they find Larry and Lemmy, who tell them that Bowser was crushed by the Tower of Yikk and are attempting to rescue him. However, Bowser grows giant and begins his battle with the tower. Larry and Lemmy still want to help him, despite Ludwig and Kamek warning them that Bowser is not aware of their presence and can unknowingly crush them. Bowser Jr. goes after them and risks his life to save them from getting crushed by the Tower of Yikk. After the battle is over, they lose sight of Bowser again, and Larry and Lemmy joined Bowser Jr., who wonders if this is what Starlow meant about Bowser working hard.

The team make their way back to Bowser's Castle, where the Best Fitness Friends stand in their way. They have Wendy trapped in a barrel and threaten to throw her into the lava. As Bowser Jr. attempts to fight them, they easily overpower him. Just as all hope was lost, the four Minion Quest captains come to the rescue. They break Wendy out of the barrel and help Bowser Jr. defeat the evil trio, forcing them to retreat once more.

Bowser Jr. finds Roy right outside the castle, although he is exhausted from fighting so many Malatone-infected minions alone ever since he abandoned the team. Bowser Jr. challenges him to a one-on-one fight, and Kamek revitalizes him to ensure the fight ends in a draw. Bowser Jr. comes victorious, despite getting himself worn-out during the fight, and Roy comes back to the team.

As they enter the castle, the Malatone-infected Morton attacks them but is defeated, regaining his senses afterwards. With all the Koopalings by his side, Bowser Jr. gives them his sincerest apologies for his behavior, and together they hunt down the BFFs for the final battle. Along the way, Dark Bowser begins spreading darkness across the kingdom. Noticing it was coming from Peach's Castle, Bowser Jr. has a strong feeling that his father is in there.

The team finds the BFFs in the castle's throne room. Before the final battle begins, Dieter questions Bowser Jr. on whether or not Bowser's Minions are evil, which he tries to deny. Bowser Jr. asks the Koopalings what they think, although Dieter only wanted a response from Bowser Jr. Since Bowser's Minions are always kidnapping Princess Peach and inconveniencing that plumber, Dieter believes they are most likely evil, but Bowser Jr. responds by saying "good and evil are outdated". The final battle then begins, first fighting the three at once, then fighting them again while they are under the influence of Malatone Formula:X, then once more after they merge together into a huge monstrous form.

Bowser Jr. with the Koopalings in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

After the BFF's ultimate defeat, Bowser Jr. gets the Skeletone Formula:D back and witnesses the Dark Star's destruction, believing Bowser is the one who destroyed it. Bowser Jr., the Koopalings, and the minions begin to celebrate their victory as Bowser is brought back to the castle, injured after another fight with Mario and Luigi. As Bowser rested, Bowser Jr. attempts to tell him the story of his journey, but with no success. Later, Bowser Jr. presents the Skeletone to his father, who decides to take some due to feeling a little bloated from the Vacuum Shroom. Bowser Jr. warns him not to take too much, but he eats the entire container and loses too much of his body mass. Bowser angrily demands to know if his son tricked him, and the story closes with him chasing Bowser Jr. out of the throne room.

In the post-game, Bowser Jr. walks around the castle bored until he asks Private Goomp, Corporal Paraplonk, and Sergeant Guy to fight with him. After defeating them, Bowser Jr. makes them his sparring partners, much to their objection. He also at one point lays about around the castle bored alongside Roy, only to decide to fight the Koopa Paratroopa Trio after a failed attempt at fraudulently supplying proof of "beating" the two to join up with the then-recently deceased Fawful, with their successfully defeating the trio. Later, Bowser hears from Ludwig of how much his son grew, and then has Bowser Jr. fight him to prove himself. However, they end up fighting non-stop for two weeks with their fights getting so out of control that the castle is badly damaged in the process.

Puzzle & Dragons: Super Mario Bros. Edition

“No way! I was setting up a 10-combo attack that would have been the END of them!”

—Bowser Jr., Puzzle & Dragons: Super Mario Bros. Edition

Bowser Jr. in Puzzle & Dragons: Super Mario Bros. Edition.

Bowser Jr. also appears in Puzzle & Dragons: Super Mario Bros. Edition, serving as a boss at World 6-Tower 2, World 7-Tower 2, and World 8-Tower 3. He also appears in the final battle, alongside the Koopalings and his father, as a separate entity.

Bowser Jr. is a Light attribute character, and when allied with Mario, his skill changes all Heart Orbs into Light Orbs, and all Light Orbs into Dark Orbs. His Awoken Skill decreases the number of turns that are required to first use skills when starting a course.

Bowser Jr. has a couple skills that he can use when fought as a boss. His Status Barrier can render all status defects (such as defense reductions and turn delays) ineffective, while Junior Smash can cut the player's current HP in half. Bowser Jr. can even increase his ATK, along with Binding random allies in the player's party. His standard attack is to throw Bob-ombs at the player.

Bowser Jr. joins the player after he is been defeated at ★World 8-Tower 3. After he joins the player, Bowser Jr.'s position as a boss is taken over by Boom Boom.

Bowser Jr. also offers one of the highest HP and ATK stats in the game, but his RCV is quite low.

Mario Sports Superstars

Bowser Jr.'s Super Rare Card in Mario Sports Superstars

Bowser Jr. is a playable character in Mario Sports Superstars. He is billed a Speed character in most sports, sharing the trait alongside Baby Mario, Baby Luigi, and Diddy Kong. In tennis, Bowser Jr. is instead billed a Tricky character, consistent with the Mario Tennis series, so Bowser Jr.'s shots have a tendency to curve. Bowser Jr.'s default drive in golf is 215 yards, and his shots travel straight and slightly low. In this game, Dolores Rogers' voice clips from previous games are reused alongside those of Caety Sagoian, Bowser Jr.'s current voice actor. Bowser Jr.'s special boost in horse racing and his special batting technique in baseball are based on the paint from his magic brush, while his personal emblem is the face of the Jr. Clown Car.

Mario + Rabbids series

Mario + Rabbids Kingdom Battle

“And YOU. Stay away from Spawny! As a matter of fact, stay out of my way. PERIOD. I have things to do and daddy issues to repress!”

—Bowser Jr., Mario + Rabbids Kingdom Battle

Bowser Jr. in the Junior Clown Car.

Bowser Jr. appears in Mario + Rabbids Kingdom Battle, but this time he has a much bigger role than his father. He is the central antagonist, and the leader of the Rabbid enemies until the Megabug gains control.

Bowser Jr. is first seen spying on Mario's team as they follow Spawny up the toy block tower in the Ancient Gardens. As Mario approaches Spawny, Bowser Jr. appears and tricks Spawny into helping him, intending to use the SupaMerge to create an army to conquer the Mushroom Kingdom to impress his father when he returns from vacation. Junior gives Mario a giant Banana and unleashes Rabbid Kong on them.

Bowser Jr. later attacks Mario's team in Sherbet Desert, ramming Mario's two partners with the Junior Clown Car. He gloats about how, when he defeats Mario, no one will be the boss of him. However, he is interrupted by a phone call from Bowser, who asks his son if he has finished his chores. Afterwards, Bowser Jr. flies off with Spawny to plot to destroy Mario.

Later, Mario's team manages to open the icebox gate using Rabbid Mario, who is frozen in a block of ice. On the other side, they find Bowser Jr. and Spawny in front of a large mound of rock and ice. With Spawny getting afraid, Bowser Jr. grabs him and points him at the mound, creating Blizzy & Sandy.

Bowser Jr. and Spawny later confront the heroes at the top of an ice mountain, near a refrigerator. Junior attempts to coax Spawny into creating another fusion (going so far as to threaten him), but Spawny refuses, crawling around his grasp. Eventually, Spawny falls out of the Junior Clown Car and into the refrigerator as his visor activates. The refrigerator then falls down the mountain, much to Mario and Bowser Jr.'s mutual horror. Bowser Jr. angrily tells Mario to stay away from Spawny, before saying to stay out of his way entirely and flying off.

Having retrieved Spawny, Bowser Jr. sends the heroes e-mails by hacking their original sender, telling them to gather the "Relics of Goodness" - a gramophone and a Boo balloon - and use a full moon to awaken a being known as "Tom Phan". He eventually confronts them in a theater in Spooky Trails. He attempts to coerce Spawny once more, but, after Spawny fails to do anything, Bowser Jr. scares him by pulling his mask over his mouth and shouting. He uses Spawny to fuse the balloon, the gramophone, and a Rabbid together to create "Tom Phan" - the Phantom.

Mecha Jr.

Bowser Jr. is finally confronted in his factory in the Lava Pit. Pressing a button in his Junior Clown Car, Bowser Jr. summons Mecha Jr. and throws Spawny into the hatch in its stomach before engaging Mario's team. However, the machine is defeated and goes haywire. Bowser Jr. ejects the clown car and grabs Spawny, narrowly escaping getting crushed by the mecha's hammer, but the resulting explosion knocks Spawny out of his grasp and into a hole. He flees as Mario's team reaches the edge.

Bowser Jr. returns shortly after the Megabug gains its physical form, blaming the heroes for Spawny getting abducted and the Megabug forming. Bowser Jr. notes that his father is still away and there is still time for Mario's team to fix everything; however, he then gets a text message from Bowser saying that he has decided to return home early. Realizing his father will be attacked by the Megabug, Bowser Jr. asks Mario's team to help him before flying off to Bowser's Castle.

When Mario's team arrives at Bowser's Castle, Bowser Jr. frantically asks them to help his father, who has been defeated by the Megabug. Beep-0 suggests the team goes back to Peach's Castle to get reinforcements, but Bowser Jr. begs them to help Bowser and admits that the situation is his fault. Bowser Jr. flees as the Megabug fuses with Bowser, only being seen for a brief second as the Megabug charges at Mario's team after the battle.

After being freed from the Megabug, Spawny is caught by Bowser Jr., who returns him to the heroes. Humbled, Bowser Jr. thanks the heroes for saving his father and promises to try to be nicer in the future. Bowser Jr. then laments that he will take his punishment once Bowser wakes up, though he tries to convince Mario to take the blame instead. However, Beep-0 decides that they should return to Peach's Castle and, though visibly annoyed, Bowser Jr. allows them to leave.

In the Donkey Kong Adventure DLC (taking place after Ancient Gardens), Bowser Jr. and Spawny spot Rabbid Kong at the Time Washing Machine, who then touches a button that electrocutes him. He then smashes the machine, which causes him to be warped into another dimension. Spawny then fires at the vortex, closing the Washing Machine. Bowser Jr. sees Mario, Luigi, Rabbid Peach, and Rabbid Luigi approaching, who also notice what is going on, and he flees. Soon after Bowser Jr. leaves, Rabbid Peach and Beep-0 are taken with the Washing Machine and disappear, leaving Mario, Luigi, and Rabbid Luigi behind.

The Mega Bite weapon is based on Bowser Jr.

Mario + Rabbids Sparks of Hope

Although Bowser Jr. does not appear in Mario + Rabbids Sparks of Hope, he is briefly mentioned by Beep-0 before the battle with Darkmess Bowser when he says that they beat the Megabug soundly in front of him.

Dr. Mario World

Bowser Jr. is a playable doctor in Dr. Mario World, referred to as Dr. Bowser Jr.. Dr. Bowser Jr. is a reward in World 3's special stage since version 1.2.0, though beating the stage prior to the update allows him to be obtainable through the doc box. Dr. Bowser Jr.'s skill involves bubbles, where it is represented by him sitting in his Junior Clown Car and then using it to punch the targets to eliminate them. In stage mode the skill pops up to 10 of them, while in versus mode it hides viruses in the opponent's play area inside bubbles, where it is up to 2 viruses at level 1 and 10 viruses at level 5. In stage mode, using this skill when there are no more bubbles left eliminates a random virus or object (if there are no viruses left), although capsules cannot be removed by this skill.

Super Nintendo World

Bowser Jr. appears in Super Nintendo World. In the Power Up Band Key Challenges attraction, he has stolen Peach's Golden Mushroom and given five keys to his minions. After attendees recover three of these keys, they can fight Bowser Jr. in an interactive boss battle titled "Bowser Jr. Shadow Showdown." Bowser Jr. appears in the Bob-omb Battlefield painting inside Peach's Castle if it is viewed from the doorway leading to the main theme park area.

Characteristics

Physical description

The current appearance of Bowser Koopa Jr. in the Encyclopedia Super Mario Bros.

Bowser Jr.'s bandana as seen in recent games

Bowser Jr. has a yellow skin tone that lacks the tan seen on his dad and most of the Koopalings, as well as a light green head, with small horns on each side, each being circled with orange rings (except for his paper appearances), small circular eyes, that are black in color and lack sclera and irises, as well as his father's fiery orange hair and eyebrows; his hair being tied up into a top-ponytail. His mouth is wide, puffy, and con-vexed, with a large snout having one, fang-like tooth in the upper left corner, with the exception of his in-game appearance in Super Mario Galaxy, in which he is depicted as having two fangs, one on each side. Just like most members of his species, Bowser Jr. has sharp claws on his fingers and toes and a rounded, four-ribbed plated belly, as well as chubby, white-padded feet. His shell is green, lined with a white encasing, and the multiple, short spikes are circled with orange rings, similar to his father's shell. He has also been shown with a considerable amount of strength, seen in Super Mario Sunshine and New Super Mario Bros. where he is able to carry Princess Peach with little to no problem.

Bowser Jr. bears a striking resemblance to his father. The similarity is even more apparent in Mario & Luigi: Partners in Time, with Baby Bowser looking almost exactly like Bowser Jr., but with a different, plain white bandana. In Yoshi's New Island, Baby Bowser looks even more like Bowser Jr., but without the bandana. By contrast, Bowser Jr. typically wears a white bandana that is decorated with drawn-on fangs, in order to depict his father's mouth, and worn like a mask, though in his very first appearance, the bandana was blue and had a picture of Mario's nose and mustache drawn on it, having been used with the purpose of disguising himself as Shadow Mario. In some of Bowser Jr's earlier appearances, such as Mario Golf: Toadstool Tour and Mario Power Tennis, he wears his bandana over his mouth, whereas in later appearances, such as Mario Party: Island Tour and Mario Golf: World Tour, he wears it around his neck. Rather than sporting the same spiked cuffs the male Koopalings have, Bowser Jr. has spikeless, metal cuffs on his wrists, like Baby Bowser since Yoshi Touch & Go.

Bowser Jr. next to Peach in Super Mario Galaxy

Bowser Jr.'s exact size varies from game to game like his father's. He was smallest in Super Mario Sunshine and some spin-offs, where he is half of Mario's size. As of the New Super Mario Bros. series he is roughly Mario's size. In Super Mario Galaxy he has grown considerably, towering over Princess Peach. He usually appears to be larger than Lemmy, and has a chubby frame similar to Ludwig's, though smaller.

Bowser Jr.'s appearance in the Super Smash Bros. series is unaltered when compared to the other Super Mario characters, including his father. In Super Smash Bros. Ultimate, however, Bowser Jr.'s color scheme is slightly darker and subdued, while his hair, horns, spikes, and shell receive simple detailing, similar to Bowser. However, Bowser Jr.'s scales remain undefined. These details are also expressed by the Koopalings.

In Super Mario Maker, Bowser Jr. receives new designs based off the graphical styles of Super Mario Bros., Super Mario Bros. 3, and Super Mario World. However, it is the Super Mario Bros. style that changes his appearance the most, since he is depicted with regular eyes, as opposed to his beady ones, while perpetually grinning with a row of visible teeth. In the Super Mario Bros. 3 style, he always has a serious expression on his face.

In Dr. Mario World, Bowser Jr. is given clothing for the first time: he wears dark green pants, a plain white collared shirt with an orange tie on top, and a white lab coat. Additionally, Bowser Jr. sports a stethoscope around his neck; however, he does not wear a head mirror like many of the other doctors, and still retains his spikeless armcuffs.

Because of Super Mario creator Shigeru Miyamoto's preference for left-handed characters like himself, Bowser Jr. is left-handed. Despite this, he plays right-handed, by default, in Mario Power Tennis, and while he is left-handed while fielding in Mario Super Sluggers and Mario Sports Superstars., he appears on the right-handed side of the batting field.

Personality

Bowser Jr. is usually portrayed as energetic, precocious, and driven, yet lonely.

“Good and evil are outdated, simplistic terms! Everything is relative! Is it wrong for me to help my dad try to take over the Mushroom Kingdom?”

—Bowser Jr., Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

Bowser Jr. is bold, reckless, and energetic, but also easygoing, helpful, and friendly depending on the situation. He often acts as an adversary to Mario and friends and helps his father make trouble for them. This has been the case ever since his father pit him against Mario in Super Mario Sunshine. This continues in several games such as Super Mario Galaxy, New Super Mario Bros. and more. Despite that, he does not mind being an ally to Mario and is seemingly warming up to him overtime, evident in games such as Paper Mario: The Origami King and Bowser's Fury. In Fortune Street and Bowser Jr.'s Journey, he is shown to have a sense of humor, partaking in sarcasm and running gags. Bowser Jr. often looks up to and takes after his father, evident in his motto ("Grin and bear it. When that don't work, grin and crush it.") from Mario Kart Wii. Just like his father, he often hates losing, sometimes believing his opponents cheat or just get lucky. Despite that, they are fairly different. For example, he often has a better attitude than his father, evident in games such as Mario & Sonic at the Olympic Winter Games and Super Mario Party where he simply accepts defeat and vows to work harder to do better next time.

He is also quite bright, with his Final Smash trophy in Super Smash Bros. for Wii U stating he is brainier than his father. For example, he is fascinated by machinery that he often invents and employs in his fights against Mario, such as his Boomsday Machine from Super Mario Galaxy 2 and the pinball machine in Mario Party DS. He is described by that game as obsessive about little details in the things that he makes as well as never being quite satisfied with his own work. He also has a habit, when energized or excited, of jumping from one foot to the other. However, this varies depending on the situation as in other cases he is shown to be easygoing and laid-back. It is revealed by his father in Mario Party: Island Tour that Bowser Jr. desires to be a hero. This explains why his father initially had to deceive him to go against Mario in the first place as well as why he often mentions his father as his motivation for being villainous.

It is also stated that he harbors a lonely side that he does not let other people know about, first alluded to in Mario Party DS. This aspect of his personality was explored in greater depth in Mario & Luigi: Paper Jam with his friendship to Paper Bowser Junior, and the depths the two go to try to keep Paper Bowser Jr. from being forced to return to his own world. A similar depiction of loneliness was also showcased in the Nintendo Switch Online service trailer's NES portion, where he attempted to ask his dad to let him play his game with him but then nearly walked away dejected when the Koopa King initially ignored him. He also seems more willing to swallow his pride than his father, such as when he convinced Bowser to accept an invitation to a party after their defeat in Mario Super Sluggers, when he apologized to the Koopalings in Bowser Jr.'s Journey, or when he apologized to and begged Mario to rescue his father from the Megabug's influence in Mario + Rabbids Kingdom Battle. He is also quite supportive, such as when he is conversing with his father, or with Mario and friends in Mario Party Superstars.

Powers and abilities

“Bwaha, that was waaaay too easy. I'm too strong for my own good. It's my princely curse.”

—Bowser Jr., Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey

Despite his young age and size, Bowser Jr. is very skilled, powerful, and a formidable opponent to the Mario Bros. From his first appearance, he has shown remarkable talent with mechanics and computers, able to skillfully invent and pilot vehicles and giant robots as well as hack emails. He is just as acrobatic as Mario and can perform the same jump techniques. He is also able to take on his Shadow Mario form through the use of his magic brush and a bandana that has drawing of Mario's moustache. When using his magic brush, he can create goop and graffiti infused with different effects, enemies such as Goobles and Proto Piranhas, Yoshis, and even bosses such as Petey Piranha and King Boo. His graffiti also has the power to transport people, as seen in Bowser's Fury. He also has high levels of skill at wielding it. He rotates the magic brush with one hand effortlessly and uses it as an offensive combat weapon against his opponents. Bowser Jr. is shown to be fast and skilled, though at times he may be given varied stats. Being the heir to the royal Koopa line, Bowser Jr. seems to have some of his father's traits. He is usually physically powerful like his father in spite of his small frame, and has shown off great levels of durability to the point of being able to survive near-death situations. This is evident in Super Mario Galaxy, where he falls into the gigantic sun after his father's defeat, and is later shown to be alive back in Mushroom Kingdom, as well as New Super Mario Bros Wii, where he survives after being crushed by Bowser's collapsing castle. Like his father, Bowser Jr. can do a normal shell spin, but in some games he has also shown he is able to do a 'reverse shell spin' where he balances on one of the spikes on his shell and spins like a top, usually with his arms, legs, and head outside of the shell.

Bowser Jr. was, at first, unskilled in breathing fire as shown in Mario Strikers Charged where he attempts to breathe fire like his father in his entrance, only to breathe smoke and a tiny flame. This changes in New Super Mario Bros. Wii, where he can breathe fireballs that can home onto opponents, and creates a large blaze of fire when the fireball is on contact with the ground. In New Super Mario Bros. U and Super Mario Bros. Wonder, he can breathe fireballs consecutively. In Mario & Luigi: Dream Team, he is able to breathe a stream of fire. He can also withdraw and duck into his shell for offensive and defensive purposes and uses Koopa Shells as weapons in New Super Mario Bros. In Mario Strikers Charged, he has a Super Ability that shrinks his opponents called Sonic Roar! where he emits large sonic waves by screaming loudly. He uses this as a Mega Strike as well. Bowser Jr. appears to excel in magic as shown in Mario Super Sluggers where he turned Daisy into a stone statue, as well as in New Super Mario Bros. where he performs necromancy to revive his father at the end of the game. This is also supported in Paper Mario: Sticker Star, where he can Paperize, create a defensive shield, and heal. Bowser Jr. is also surprisingly strong for his size as demonstrated in Super Mario Maker, where he possesses the ability to ground pound and paralyze any opponents that stay on the ground, an ability performed by most large and strong characters like Bowser, Morton, Roy, and Ludwig. He demonstrates his deceptively vast strength once more in Mario & Luigi: Paper Jam, where he can easily throw a gigantic cannonball several times his own size at the Mario Bros. and Paper Mario.

Relationships

Family and friends

Bowser, Bowser Jr., and the Koopalings on an airship.

Bowser Jr. idolizes his father and strives to be like him. In Mario Party: Island Tour, Bowser Jr. challenged Bowser in Bowser's Tower, and in Mario Strikers Charged, he challenges his father in one of the Striker Challenges, but aside from these instances of father-son rivalry, the two have been shown to share a close bond, appearing as partners in various sports and spin-off titles, and Bowser Jr. aids his father in many of his plots. While he cares for his son, Bowser's selfishness and single-minded determination to defeat Mario occasionally leads him to treat Bowser Jr. like a minion, and when he is wrapped up in one of his plans he has a tendency not to listen to what his son has to say. In Mario + Rabbids Kingdom Battle, Bowser Jr. claims to have "daddy issues to repress". Initially, Bowser even tried to manipulate the child into helping with the fight against Mario by telling him that Peach was his mother, although he eventually felt guilty and came clean. Bowser Jr. had figured it out by then, but still wants to fight alongside his father regardless of the deception, revealing his deep loyalty and love for his father. Bowser, meanwhile, is very protective of his boy and becomes enraged whenever his son is harmed in any way, as seen in New Super Mario Bros. and Mario & Luigi: Paper Jam. In the Nintendo Switch Online service trailer in the September 13 Nintendo Direct, during the NES portion, Bowser Jr. attempts to have his father let him play his NES game with him, though Bowser was too busy playing Ghosts 'n Goblins to notice, causing Bowser Jr. to initially walk away dejected, though after Bowser noticed this, feeling guilty, he then provides his son with an extra Joy-Con so they could play Ice Climbers together. As revealed in his Super Smash Bros. Brawl trophy, Bowser Jr. was also motivated to kidnap Princess Peach by his own affection for her, and in Mario Superstar Baseball, he continues to call her "mama", suggesting he wishes she really was his mother. In the Nintendo Switch online service trailer in the September 13 Nintendo Direct, during the NES portion showing online gameplay, Bowser Jr. and Princess Peach were shown playing against each other remotely and having a fun time, with Bowser when witnessing this looking baffled. His actual mother has not been revealed, although Shigeru Miyamoto once jokingly claimed he was the mother. Although genuinely loyal to his father, he is not above pranking Bowser, which is implied by Bowser, or rather, Dry Bowser accusing him of his transformation into such being another of Bowser Jr.'s pranks on him, although Bowser Jr. denied it, and reminded him that, if anything, he tried to warn his father against ingesting the entire Skeletone container beforehand, and later confirmed in Bowser's Fury, where he painted his dad while the latter was asleep, which ended up causing a lot of trouble when Bowser became Fury Bowser as a result.

As the heir to the throne, Bowser Jr. is naturally a high-ranking member of the Koopa Troop. However, there is some ambiguity about where he stands with respect to the Koopalings, who were originally portrayed as Bowser's own seven children. Bowser Jr. and the Koopalings have been shown working together on a few of Bowser's plots, although they have no formally revealed relationship. His first spoken interaction with the Koopalings has been with Roy in Mario & Luigi: Paper Jam, where the two seem comfortable enough around each other that Roy was able to casually call Bowser Jr. a 'squirt' (or 'bocchan' in the original Japanese) without angering him. However, Roy was still subservient enough that he was easily intimidated when Junior threatened to tell his father on him if Roy did not give him something he wanted, although Roy's confusion seems to suggest this is not a typical occurrence and the threat itself is only present in the English translation. It is also noted that Bowser Jr. almost always wears his bandana on his face in the presence of the Koopalings in New Super Mario Bros. Wii (an exception being when it is forcibly knocked off in a crash-landing airship), which may suggest that he strives to be higher in their presence. He seems to be comfortable working with them, as they all act as a group at the end of Puzzle & Dragons: Super Mario Bros. Edition when Bowser calls on all of them for backup (Lemmy is even seen riding with him on his Junior Clown Car) and in their collaboration for his Super Smash Bros. for 3DS / Wii U trailer. Bowser Jr.'s Journey seems to highlight more of their relations within the ranks of the Koopa Troop, with the Koopalings regularily referring to him as Lord Junior. However, Bowser Jr.'s selfish and arrogant nature initially lead most of the Koopalings to abandon him; with Roy notably being annoyed with his behavior and leaving as a result, while Larry and Iggy both leave when Bowser Jr. outwardly states he does not need them. The only Koopaling who stood by Bowser Jr. the entire time, despite his selfishness, was Morton, who went as far as to give Bowser Jr. a charred Drumstick out of kindness. This would later serve as one of the bigger points in Bowser Jr.'s turnaround, thinking back to Morton's kindness when realizing how selfish he had been and, coupled with Kamek reminding him that the minion's loyalty to Bowser was out of respect, Bowser Jr. sets out to save the Koopalings. Later in the story, Bowser Jr. starts to show more respect to the Koopalings, going as far as to save Larry and Lemmy from being stepped on by the Tower of Yikk and apologizing to them.

In contrast to his father and his paper counterpart (both of whom worked together out of pragmatism and strongly implied that they would turn against each other once they succeeded in their goals), Bowser Jr. had genuine kinship with his paper counterpart, and was even saddened when his paper counterpart was sucked back into the book for Paper Mario.

In Mario + Rabbids Kingdom Battle, he has a complicated relationship with a Rabbid character that he names Spawny. Bowser Jr. asks Spawny to join him on his mission to defeat Mario and take over the Mushroom Kingdom with the power of the SupaMerge headset that Spawny has been bonded to. Spawny accepts, and at first it appears that the two share a mutual friendship. However, the SupaMerge headset seems to take a heavy toll on Spawny with each use, and he becomes reluctant to use it. Bowser Jr., meanwhile, seems enthralled by the power of the SupaMerge and begins to scare and level threats at Spawny to force him to use the headset to create more and more nightmarish minions for his plans. As the game goes on, Spawny's role in Bowser Jr.'s schemes appears less and less as a willing participant. At the same time, Bowser Jr. still appears to care for the Rabbid enough that he seems visibly distraught and saddened on two separate occasions that Spawny seems to fall to his doom, and later angrily confronts Mario and friends when Spawny gets kidnapped by the Megabug while in their custody. At the end of the game, after Spawny is safely recovered, Bowser Jr. personally returns Spawny back to Mario and his friends and lets him go free.

Bowser Jr. befriends Olivia in Paper Mario: The Origami King, generally getting along well with her. Olivia herself regards Junior as a friend, as seen in her dialogue before fighting King Olly. Bowser Jr. is mildly upset when Olivia inadvertently starts complimenting his Junior Clown Car instead of him upon having his colors restored, although later in Hotfoot Crater, he was willing to sacrifice himself so that Mario and Olivia can continue upwards to reach Peach's Castle.

Enemies

Bowser and Bowser Jr. fighting Mario and Luigi in Mario Kart: Double Dash!!

Bowser Jr.'s greatest foe is Mario, whom he despises deeply, and wants to defeat in order to prove himself to his father. Bowser Jr. helps his father in nefarious schemes to take over the Mushroom Kingdom or kidnap Princess Peach, but Mario is always there to foil their plans. Bowser Jr.'s animosity towards Mario is greatly shown in Super Mario Sunshine, where he frames him for vandalizing Isle Delfino, thus causing him to get arrested; additionally, he challenges Mario in several levels as Shadow Mario. Later on, Bowser Jr. says that he is trying to "protect his mama from the bad man, Mario." When Mario appears for the final confrontation against Bowser, Bowser Jr. shows disdain for the plumber's presence, and says "You again? Don't you ever give up?" In Super Mario Galaxy 2, Bowser Jr. verbally expressed a desire for Gobblegut to eat Mario alive. After Super Mario Sunshine, Junior's hatred for Mario has been toned down. He doesn't despise him as much as his father does, mostly seeing him as "a thorn in his side" (as stated in Fortune Street) instead of an archenemy as Bowser does. In some games such as Paper Mario: The Origami King, Mario Party: Island Tour, and Bowser's Fury, Bowser Jr. has even shown a willingness to team up with Mario if a greater threat is present, although oftentimes, he is only in it for the sake of assisting his dad, and has stated that he would never enlist Mario's help if he did not have to. In fact, as soon as their alliance is over, he often goes right back to antagonizing Mario without bothering to thank him.

Bowser Jr. has fought Luigi, Yellow Toad, and Blue Toad in the New Super Mario Bros. games, as well as others in the former's case. Bowser Jr. equally loathes these characters, since they assist Mario in defeating him, as well as ruining his father's plans. Bowser Jr. has also mistreated Toads in general, due to trapping them in ? Blocks in New Super Mario Bros. Wii, and terrorizing them during Bowser's many invasions of the Mushroom Kingdom.

Bowser Jr. disdains The BFFs for wreaking havoc and mistreating his father, the Koopalings, and his minions, determined to get revenge and defeat the BFFs. Jr. also loathes King Olly for folding his father, and ravaging the world with origami.

Trivia

• The name "Bowser Jr." predates the character, as it was first used in Prima Games coverage of Yoshi's Story to refer to Baby Bowser.
• While the Koopalings are fought on airships in Super Mario Bros. 3 and Bowser Jr. is fought in towers in New Super Mario Bros., they swapped locations in New Super Mario Bros. Wii, as Bowser Jr. is fought on airships, whereas the Koopalings are fought in the towers and castle of each world.
• In the New Super Mario Bros. games, Bowser Jr.'s actions, such as running and jumping, create sound effects with a high pitch unique to him. This distinct sound effect was mimicked by Bowser during the ending of New Super Mario Bros. U.
• In the Collector's Edition of Monopoly Gamer, Bowser Jr. is the "Final Boss" in the Boss Card deck. He replaces his father, Bowser, as "Final Boss" from the Standard Edition, as Bowser is instead a playable character in the Collector's Edition.
• In an instructional video posted by Nintendo for creating a Nintendo Account, Bowser Jr. is used as an example for an account's personal information, with his birthday listed for March 3, 2010.
