Being the arch-nemesis of [[Baby Mario]], who is the infant form of [[Mario]], he is the infant form of [[Bowser]], and he commonly accompanies [[Kamek]] as the main antagonist in their appearances, most notably the [[Yoshi's Island (series)|''Yoshi's Island'' series]]. Kamek is mainly responsible for his child rearing. Baby Bowser looks almost identical to [[Bowser Jr.]], even sometimes sharing his voice. The main difference in the visual design between the two is that Bowser Jr. has a drawing on his bandanna, while Baby Bowser's is blank, or he does not wear it at all.

Adult Bowser has been portrayed as an infant in other media, namely in the episode "[[Two Plumbers and a Baby]]" in ''[[The Super Mario Bros. Super Show!]]'' and the episode "[[Toddler Terrors of Time Travel]]" in ''[[The Adventures of Super Mario Bros. 3]]'', though the Baby Bowser character is considered a distinct entity from these forms.

==History==
===''Yoshi's Island'' series===
====''Super Mario World 2: Yoshi's Island'' / ''Yoshi's Island: Super Mario Advance 3''====
[[File:Baby Bowser SMW2YI Artwork.png|thumb|left|Artwork from ''Super Mario World 2: Yoshi's Island'', showing the original design of Baby Bowser]]
Baby Bowser is the final boss in ''Super Mario World 2: Yoshi's Island'' and [[Yoshi's Island: Super Mario Advance 3|its port]]. He appears at the end of [[King Bowser's Castle (Super Mario World 2: Yoshi's Island)|his castle]] as Kamek is demanding that Yoshi hand over Baby Mario, waking and complaining that "it's too noisy". He then [[Ground Pound]]s Kamek and kicks him away, noticing Yoshi immediately afterward and wanting to ride the "gween donkey." Baby Bowser attacks by ground pounding wherever Yoshi is, creating shockwaves on the ground, which Yoshi can also do to attack him. If Baby Mario is knocked off of Yoshi's back, Baby Bowser climbs onto his back instead; if Baby Mario is saved afterward, Baby Bowser will be stunned. After three hits, Baby Bowser is beaten. Kamek shows up and uses his magic on him, causing him to grow into the {{wp|Kaiju|kaiju-sized}} [[Mega Baby Bowser|Big Baby Bowser]], destroying the castle around him. Baby Bowser ends up being returned to his normal size, and knocked out. Afterward, Kamek reappears and vows revenge before flying off with Baby Bowser. Yoshi then sprints up to the [[Stork]] and [[Baby Luigi]], freeing them both and allowing the Stork to deliver the babies to their parents. Baby Bowser is also the only boss who must be defeated before Kamek casts a spell on him.

====''Yoshi's Island DS''====
[[File:Baby Bowser on Yoshi YIDS artwork.jpg|thumb|Artwork from ''Yoshi's Island DS'' of Baby Bowser riding Yellow Yoshi, something that is not possible because Baby Bowser is never played in [[Fortress|fort]] levels.]]
Baby Bowser is a major antagonist in ''[[Yoshi's Island DS]]''. Baby Bowser is at his castle when his future self shows up to kidnap the [[star children]] and gain control of the universe. Baby Bowser is ironically abducted by the future Kamek from the past Kamek and brought to Bowser's Castle. When he realizes the circumstances, he insults his grown-up self and his plan. Baby Bowser is kicked out of the castle by Bowser, oblivious to Baby Bowser being one of the [[star children]]. Baby Bowser vows revenge after landing and then yells into the sky to try and remind his adult self that they are the same entity. Baby Bowser then notices Baby Mario and tells him he saw Baby Luigi in Bowser's Castle. Baby Bowser then realizes that he has just landed on Yoshi and is stoked to get a ride from him. Baby Bowser becomes playable for the remainder of [[World 4 (Yoshi's Island DS)|World 4]]. Baby Bowser's [[fireball]] attack replaces Yoshi's ability to [[swallow]], and the attack is essential for melting ice cubes. Once [[Big Guy the Stilted]] is defeated, Baby Bowser leaves Yoshi's group in an attempt to hitch a ride from the future Kamek as he flies off to report to the adult Bowser. However, Baby Bowser loses his grip and falls off of Kamek's broomstick. Baby Bowser fought with [[Baby Wario]] over treasure at some point, and he rejoins the Yoshis when they reach Bowser's Castle. Baby Bowser eventually betrays them and attacks Yoshi and the other babies, believing they are after his treasure. The fight goes much like the previous one, but faster. After a defeat, Baby Bowser is taken away by Kamek, leaving the group to the future Bowser, who is angry at what Yoshi did to his younger self. In the ending, following adult Bowser's defeat, Baby Bowser falls off Kamek's broom and lands on a barge carrying his treasure, now claimed by Baby Wario, and the two get in a fight again.

====''Yoshi's New Island''====
[[File:BabyBowserEggIsland.png|thumb|left|Screenshot from ''Yoshi's New Island'', showing Baby Bowser planning to convert Egg Island into his resort.]]
Baby Bowser is a major antagonist and the penultimate boss in ''[[Yoshi's New Island]]''. He, Kamek, and his older self are all the main antagonists. Baby Bowser's plan is to turn [[Egg Island]] into his vacation home, so the Yoshis go out to stop Baby Bowser's plan, as well as rescue Baby Luigi along the way. The end scenario is similar to ''Super Mario World 2: Yoshi's Island'': Baby Bowser is once again awakened from his slumber, only to crush and kick Kamek out. He soon notices the "familiar gween donkey" and proceeds to try and ride Yoshi again. Baby Bowser is fought in a battle reminiscent of his battle in ''Super Mario World 2: Yoshi's Island''. His voice is a higher-pitched version of [[Bowser Jr.|his future son]]'s voice. After Mega Baby Bowser is defeated, he ends up shrinking back to Baby Bowser and the stork and Baby Luigi are rescued. However, if the Yoshis never used the [[Flutter Wings]], [[Bowser|his future self]] appears out of nowhere, making Yoshi and Baby Mario battle him before they can do so.

===''Yoshi's Story''===
[[File:BabyBowserYSArtwork.png|thumb|160px|Artwork from ''Yoshi's Story'']]
Baby Bowser is the main antagonist of ''[[Yoshi's Story]]''. He steals the [[Super Happy Tree]] and turns the entire island into a pop-up book. The [[Baby Yoshi]]s, who have been on an adventure to stop Baby Bowser, encounter him in his castle, where Baby Bowser is dueled by one of the Baby Yoshis. Baby Bowser is riding his "[[Ghost (Yoshi's Story)|pet]]," and the player can throw [[Bob-omb|Bob-bomb]]s at Baby Bowser to knock him off. Baby Bowser then recites a "poem" about how he is the king, and intends to smash Baby Yoshi and thus demands the latter say goodbye. On the ground, the battle continues with Baby Bowser shooting fireballs, throwing bombs, and generating shockwaves. After a few more hits, Baby Bowser surrenders in defeat. Just before he is carried out by his Toadies while sobbing, Baby Bowser allows the baby Yoshis to have the Super Happy Tree back, admitting that the fruit tasted terrible.

Coincidentally, [[Prima Games]] coverage has referred to Baby Bowser as "Bowser Jr.", predating the debut of [[Bowser Jr.|the actual character]] in ''[[Super Mario Sunshine]]''.<ref>{{cite|author=Prima Bath|title=''Nintendo 64 Game Secrets, 1999 Edition'' Prima's Official Strategy Guide|page=117|isbn=0-7615-2103-8|date=April 7, 1999|language=en-us|publisher=[[Prima Games]]}}</ref><ref>{{cite|author=Prima Bath|date=April 21, 1999|title=''Ultimate Nintendo 64 Pocket Power Guide, 1999 Edition'' Prima's Official Strategy Guide|publisher=Prima Games|page=93|language=en-us|isbn=0-7615-2083-X}}</ref>

===''Mario Artist: Paint Studio''===
Baby Bowser's artwork from ''Yoshi's Story'' is reused as a stamp in ''[[Mario Artist: Paint Studio]]''. 

===''Super Smash Bros.'' series===
Baby Bowser appears in the form of a few collectible items in the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]]. In ''[[Super Smash Bros. Melee]]'', a [[Trophy (Super Smash Bros. series)|trophy]] of Baby Bowser as he appears in ''Yoshi's Story'' can be obtained randomly in single-player modes or from the {{iw|smashwiki|Lottery}} randomly. In ''[[Super Smash Bros. Ultimate]]'', Baby Bowser is a Legend-class Neutral-type {{iw|smashwiki|primary spirit}} with two empty slots and no extra attributes. The [[Spirit (Super Smash Bros. Ultimate)|spirit]] battle is a stamina battle which involves first fighting a tiny, orange Bowser on the Omega version of [[Find Mii]]. The stage is covered entirely in flames, meaning players get damaged if they have no lava immunity support spirits equipped. After the tiny Bowser is defeated, a large Bowser appears with more HP and with super armor.

===''Yoshi Touch & Go''===
Baby Bowser makes a cameo in ''[[Yoshi Touch & Go]]'' as one of the selectable high score icons. He also appears when Yoshi gets a [[Game Over]] with over 3000 yards on the Challenge Mode, laughing with Kamek.

===''Mario & Luigi: Partners in Time''===
[[File:Babybowserfight.PNG|thumb|The first fight with Baby Bowser in ''Mario & Luigi: Partners in Time''.]]
Baby Bowser is the secondary antagonist of ''[[Mario & Luigi: Partners in Time]]''. At the start, Baby Bowser is first seen trying to kidnap [[Baby Peach]]. Luckily, Baby Mario and Baby Luigi show up in the nick of time to play with Baby Peach. After Baby Mario defeats him however, the [[Shroob]]s attack [[Peach's Castle]]. Fortunately, everyone manages to escape on Baby Bowser's [[Koopa Cruiser]]. On the way to his castle, Baby Bowser picks the [[Mario]] and [[Luigi]] from the present to get Baby Peach to stop crying. On the Koopa Cruiser, he receives a transmission from [[Princess Shroob]] at [[Shroob Castle]]. She tells the crew something in the Shroobs' language and shoots down the Koopa Cruiser with a [[Shroob missile]].

Baby Bowser is flung away from the Koopa Cruiser on the impact, into his castle. Eventually, he realizes his archenemies and their adult selves have stolen his [[Cobalt Star|Cobalt Star Shard]] from his castle and tracked them down to the [[Vim Factory]], where he swipes both his Cobalt Star Shard and the one the Bros. have just obtained from [[Swiggler]].

Baby Bowser then flees to the peak of Yoshi's Island with his caretaker, Kamek, where he orders Kamek to snatch the [[Yoshi Cookie]]s from the [[Yoshi (species)|Yoshi]]s. When the Mario Bros. catch up to Baby Bowser at the peak, he scarfs down all the Yoshi Cookies, but starts choking. Baby Bowser then leaves to the other side of the peak after Kamek had given him some "evil" [[milk]]. While Mario and Luigi try to negotiate with him, Baby Mario and Baby Luigi gobble up all the cookies, causing Baby Bowser to become enraged. He runs off while the Mario Bros. defeat Kamek, and they corner him at the other side of the peak. Without thinking his plans through, Baby Bowser eats the Cobalt Star Shards in retribution for the cookies. As Mario and Luigi restrain him while Baby Mario attacks him to make him cough up the shards, Shroob saucers notice them. Soon after, he and the Mario Bros. are eaten by [[Yoob]].

Inside Yoob, Baby Bowser, along with the Yoshis already eaten, are put inside an [[Egg (Mario & Luigi: Partners in Time)|egg]]. When the Mario Bros. confront [[Sunnycide]], a monster within Yoob, he throws the egg Baby Bowser is in at Luigi, breaking it open. After the Mario Bros. defeat Sunnycide, Baby Bowser and all of the swallowed Yoshis escape Yoob.

Back on Yoshi's Island, Baby Bowser tells the Yoshis that he saved them from Yoob. Having believed him, the Yoshis give him the rest of their cookies. Baby Bowser then eats all of the Yoshi Cookies and gets sick. He vomits the Cobalt Star Shards, which, seemingly with [[Elder Princess Shroob|a mind of their own]], hit him and fling him off of Yoshi's Island. The Mario Bros. and [[Toadbert]] show up afterwards to tell the Yoshis that Baby Bowser was lying.

Later on, Baby Bowser heads off to [[Thwomp Volcano]] to build a new castle, where he meets his future self, Bowser. After a minor argument, Baby Bowser and Bowser team up, not knowing the other ones identity, against the Mario Bros. They end up being beaten after the battle and flung into the sky by an [[Thwomp Elevator]], where Bowser ends up in a [[time hole]] and Baby Bowser ends up on top of the [[Shroob Mother Ship]]. 

[[File:Shroob Shroom.png|130px|thumb|Baby Bowser's Shroob mushroom form]]
Baby Bowser shows up again after the Bros. have defeated Princess Shroob and, despite being warned by the adult Princess Peach, he puts the Cobalt Star Shards together and completes the Cobalt Star, releasing the Elder Princess Shroob, who turns him into a [[Shroob mushroom]]. After the battle with the Elder Princess Shroob, Baby Mario and Baby Luigi play on Baby Bowser's Shroobified form, until Baby Luigi gets hurt and his tears turn Baby Bowser back to his normal state. While the Mushroom Kingdom is cleansed of all traces of the Shroobs thanks to [[Professor E. Gadd]]'s [[Hydrogush]], Baby Bowser goes home, complaining about losing the Cobalt Star with Kamek telling him to let it go.

===''Yoshi's Woolly World'' / ''Poochy & Yoshi's Woolly World''===
[[File:Main Boss 6 Baby Bowser.png|thumb|left|Baby Bowser in ''Yoshi's Woolly World'']]
Baby Bowser is the final boss in ''[[Yoshi's Woolly World]]'' and [[Poochy & Yoshi's Woolly World|its reissue]]. Despite being the arch-nemesis of Baby Mario (who does not appear in either version), Baby Bowser is the only baby character to appear in both versions. He retains a similar voice to Bowser Jr. Statues based on Baby Bowser are a core mechanic of the game's final course, {{id|King Bowser's Castle|YWW}}, and he is the boss of that course. Baby Bowser makes no appearances in the game prior to this point, and for those unfamiliar with the Yoshi franchise he could be considered a twist villain.

The final room of King Bowser's Castle is a playroom for Baby Bowser. When entered, a cutscene plays out where Baby Bowser waits impaiently for [[Kamek]] to return with the yarn so that he can have "a big new castle". Kamek shows up and gets berated for being late. When [[Yoshi (species)|Yoshi]] appears, Baby Bowser does not recognize him but assumes he wants the yarn and attacks. Kamek assists Baby Bowser from the background.

Baby Bowser has a number of attacks that increase in scope across the boss battle. He always opens with high and short jumps in either direction, jumping an additional time off of the screen edges and Yoshi. Between his jumping, he can stop to breathe fire at Yoshi. This has a substantial wind up. Sometimes, he will jump in place to face Yoshi, then jump above directly above him. With a cry, he stops and performs a [[Ground Pound]], which is potent enough to rattle the blocks of the room in the background, cause two lava geysers to appear to Baby Bowser's left and right, and cause three red Shy Guys to drop from the ceiling. The Shy Guys land equidistant from each other. Shy Guys are destroyed on contact with Baby Bowser and any of his attacks. This includes the Ground Pound, which rattles the room enough to KO them from any point in the room. Baby Bowser can be jumped on and bounced from, but this has no effect on him. Fire breath from a [[fire watermelon]] or ice breath from an [[ice watermelon]] can interrupt his attacks. Baby Bowser can be tied up by throwing a [[yarn ball]] or [[Poochy Pup]] at him. If left alone, he will break free and resume attacking. While tied up, Yoshi can ground-pound him to inflict damage. 

Once Yoshi bounces off and Baby Bowser stands up, Baby Bowser retreats into the background to attack. He jumps to one side of the screen and shoots fire breath into the sky, raining down the main plane. The first volley drops in a staircase pattern on one side of the screen, leaving space on the opposite side. The sides are reversed for a second volley. with Baby Bowser hopping to the other side of the screen to fire. Lastly, Baby Bowser stands in the center of the screen and shoots two streams of fire at once. These streams come down from the left and right sides of the screen, leaving space in the center. This is followed up by a [[Bowser's Flame]] launched up to the center of the top of the screen. Before it comes down, Kamek causes it to grow and reknit itself to be more solid. Then it drops, splashing a puddle against the ground. Note that the splash does not inflict damage.

Baby Bowser returns to the main plane. He gains the ability to jump straight up and flutter, then spit a stream of fire directly at Yoshi while in the air. He cannot turn around during this jump, and therefore cannot fire backward. There is less time between each of his normal jumps. He can also jump to Kamek in the background, getting a ride from him while he sends streams of fire across the ground and back to the main plane. They move to Yoshi's current position, then Baby Bowser sends sends three streams forward in a spread pattern. He does this twice, with the second version using a center stream with double the width. This sequence ends on a third attack with two wide streams aimed to Yoshi's left and right. After this attack, Baby Bowser jumps back to the main plane, landing on the nearest screen edge before dropping down. Baby Bowser does not use the basic fire breath attack.

After being hit again, Baby Bowser retreats to the background and repeats his falling fire attack. However, this version ends with three Bowser's Flames, the second and third landing to the left and right of the first. Before returning to the main plane, he jumps onto and off of Kamek, aiming for the far edge of one side of the screen. While still in the air, Kamek uses his magic to increase Baby Bowser's size temporarily. In this state, Baby Bowser is immune to all attacks. Baby Bowser uses a Ground Pound, and the resulting lava geysers are larger. SHy Guys do not appear for this attack. Baby Bowser repeats this twice more, aiming for Yoshi on the remaining two Ground Pounds. The background is noticeably more rattled by these attacks, but Shy Guys are unaffected by this rattling. After the third Ground Pound, Baby Bowser returns to normal size. He can use any of his prior attacks now except for breathing fire while riding Kamek. He can even repeat the magic enhanced ground-pound attack, though he has to jump to Kamek in order to start, which telegraphs it heavily. If Baby Bowser takes damage one more time, he is defeated. 

After switching to a cutscene, Kamek uses power of the [[Wonder Wool]] to transform Baby Bowser into [[Mega Baby Bowser]]. The drastic size increase knocks the roof of the tower and both Kamek and Yoshi away, leading to the final battle. After Mega Baby Bowser is defeated, Baby Bowser returns to normal, though he stays unconscious The Wonder Wool that made up his larger body is reknit into all of the single-color-and-white Yoshis. Baby Bowser is taken away by Kamek, leading into the ending where they fly past the moon.  Baby Bowser wakes up and begins throwing a tantrum. [[Poochy]] startles the both of them from the moon, spooking Kamek and causing him to drop Baby Bowser. A skit plays out across the ending credits involving all three characters and a [[Bomb Guy]].

If the player collects all five of the Wonder Wool in King Bowser's Castle (the Wonder Wool that are collected in the level, not all the ones in the cutscenes), they reknit [[List of Yoshi designs in Yoshi's Woolly World|Baby Bowser Yoshi]], who is a playable character. Baby Bowser is the final boss of the [[Boss Tent]] where he must be fought alongside Mega Baby Bowser in a single Boss Challenge with no checkpoint between the battles. As with other Boss Challenges, Baby Bowser and Kamek move faster in this version.

===''Yoshi's Crafted World''===
[[File:YCW Kamek Baby Bowser.png|thumb|150px|Kamek and Baby Bowser in ''Yoshi's Crafted World'']]
Baby Bowser reappears alongside Kamek as one of the two main antagonists in ''[[Yoshi's Crafted World]]''. Despite being the arch-nemesis of Baby Mario (who also does not appear), Baby Bowser is once again the only baby character to appear. During the start of the game, he is seen riding on Kamek after he learned about the [[Sundream Stone]], where Kamek casts a spell pulling the Sundream Stone, resulting in the Yoshis pulling and tackling the Sundream Stone, resulting in Baby Bowser, Kamek, the Yoshis and the Sundream Stone flying into a forest, with the Sundream Stone's five Dream Gems being scattered around the island.<ref>{{cite|author=Nintendo of America|url=www.youtube.com/watch?v=dcndZNVUxFM&t=25s|timestamp=0:25|title=Yoshi’s Crafted World - Story Trailer - Nintendo Switch|publisher=YouTube|language=en-us|accessdate=June 20, 2024|date=January 8, 2019}}</ref> Unlike in the game's predecessor, Baby Bowser actively searches with Kamek for the Dream Gems. In the first level, [[Rail-Yard Run]], [[Kamek]] and Baby Bowser appear and disassemble the train, preventing Yoshi from progressing. The pair are also responsible for creating all the bosses at the end of each area in the main game. The bosses they summon in order are [[Yarrctopus]], [[Tin-Can Condor]], [[Spike the Piranha]], [[Burt the Ball]], [[Shogun of Skewers]], [[Gator Train]], and [[Mr. Geary]]. Lastly, Baby Bowser is the final boss of the game, with the exception of [[Kamek]] being the secret final boss.

Baby Bowser's battle is a battle with the [[The Great King Bowser|robot that was created by the Sundream Stone]] for him through his wish. After Mega Baby Bowser is defeated, he reverts back to Baby Bowser and Kamek picks him up and flies away with him as the game comes to an end.

==General information==
===Physical appearance===
Baby Bowser shares many physical qualities with his adult counterpart, Bowser. They both have red hair and black cuffs on their arms. Baby Bowser has cuffs on his neck in both ''Super Mario World 2: Yoshi's Island'' and ''Yoshi's Story''. In these appearances, Baby Bowser appears with spiked cuffs, while in ''Mario & Luigi: Partners in Time'' and ''Yoshi's Island DS'', his cuffs appear with no spikes. Like Bowser, Baby Bowser has two red eyebrows (black on his ''Super Mario World 2: Yoshi Island''{{'}}s sprite), a green shell with spikes, and two small nostrils on his nose. Baby Bowser also has claws on his hands and his feet. Unlike Bowser, Baby Bowser either has no horns or his horns are small and stubby, much like [[Bowser Jr.]]'s, depending on the game. When Baby Bowser is in the dark in ''Yoshi's Island'', he is shown to have yellow eyeshine. Additionally, he sports deep red blush on his cheeks in ''Yoshi's Island'', a trait that is omitted from later depictions (barring his debut game's [[Yoshi's Island: Super Mario Advance 3|reissue]]). Overall, his current physical appearance is nearly identical to that of his future son Bowser Jr. with the only difference being that he has a blank bandanna or no bandana at all. In ''Mario & Luigi: Partners in Time'', Baby Bowser was given some resemblances to Bowser Jr.

===Personality===
His personality is that of a spoiled child. He frequently throws tantrums in hopes that his minions will give him what he wants. Also, unlike his adult self who is generally caring if a little short-tempered towards his minions, he is shown to be very abusive and disrespectful to them, which is best demonstrated by how he flattens Kamek, his guardian, after the latter accidentally woke him when confronting Yoshi and demanding Baby Mario in two separate instances, as well as implied in key artwork for ''Yoshi's New Island'', where Baby Bowser had beaten Kamek with the latter's wand while undergoing a tantrum. He is greedy and also very gluttonous, as shown in ''Mario & Luigi: Partners in Time'', where he eats a huge pile of Yoshi Cookies and the Cobalt Star shards with Toadbert calling him a "little piggie". He even insulted his future self in ''Yoshi's Island DS'' and ''Mario & Luigi: Partners in Time''. He was also shown to be extremely protective of his treasure to the extent of being paranoid, turning on his allies in an instant if he even slightly suspected that they may be after it, as demonstrated in ''Yoshi's Island DS''. In ''Super Mario World 2: Yoshi's Island'' and ''Yoshi's New Island'', Baby Bowser has a tendency to speak in baby-like language, with phrases such as "gween donkey" being heard from him. Even though Baby Bowser shows no awareness of his future archenemy, Baby Mario, in ''Yoshi's Island'' or ''Yoshi's New Island'' (even simply shoving him aside so he could ride Yoshi), he does directly reference the latter in ''Yoshi's Story'' by referring to Yoshi as "Mario's little pet." Owing to his age, he also tended to [[wikipedia:Speech sound disorder#Rhotacism|mispronounce words that have "l"s or "r"s, having them come out as "w"s]], mispronouncing his "th"s as "d"s, as well as mispronouncing his "i"s as "y"s, as evidenced by his speeches to Kamek and Yoshi in both ''Yoshi's Island'' and ''Yoshi's New Island''.

===Abilities===
Even as a child, Baby Bowser demonstrated some of his adult self's traits, such as breathing fire (Either large streams of fire or fireballs) and possessing a surprising amount of strength. He can also Ground Pound and Flutter like Yoshi. He can also summon minions to attack, which is demonstrated with both his [[Ghost (Yoshi's Story)|pet]] and some Shy Guys. In ''Mario & Luigi: Partners in Time'', he has a hammer just like the baby bros. Unlike Bowser, he seems to be more active and has a bigger appetite.

When enhanced by Kamek to become Big Baby Bowser, Baby Bowser also demonstrates some degree of telekinesis, as rubble is seen being lifted as he roars and lifts his hands up. He also is shown to breath massive fireballs, either directly at Yoshi or spraying them upwards to descend in an arc. He can also ground pound, with the quakes being potent enough to literally reshift the ground by raising it upward or sink downward.

===Speech===
In ''Yoshi's Island'', his "voice" is composed of three record-skips at a low volume, two when ground-pounding (as well as brief roar when yawning). In ''Yoshi's Story'', he has a youthful, yet at the same time rasping element to his voice; when he takes damage, he uses a slightly higher-pitched version of his adult self's stock roar. In ''Yoshi's Island DS'', he reuses the same laugh as [[Boo]], which is also a sped-up version of the same stock laugh used for his adult self in ''[[Super Mario 64]]''. In most games since ''Partners in Time'', he was given a similar voice to [[Bowser Jr.]], albeit with a slightly higher pitch. 

In most games, he speaks with a text box with limited voiced dialogue. His form of speech also varies from game to game: in some games, such as ''Yoshi's Island'' or ''Yoshi's New Island'', he speaks in a somewhat childish way, using broken English and replacing some letters with "w" (e.g. "gween" instead of "green"). In other games, like ''Yoshi's Story'' and ''Mario & Luigi: Partners in Time'', however, he speaks in fluent English.
