[[File:SMB3_MortonKoopaJr.jpg|thumb|Morton, as originally depicted for ''Super Mario Bros. 3'']]

Morton made his first appearance in ''[[Super Mario Bros. 3]]'' where he, along with his siblings, aided their father in an attempt to take over the [[Mushroom World]]. At some point, Morton discovered that Mario was capable of accessing transformations, which meant [[Mario]] might prove to be a challenge, and likewise reported the discovery to Bowser. Morton usurped the [[Kings|king]] of [[Desert Land]] and took over. He used the same attack pattern as [[Larry]], but in the end he was defeated by Mario.

Morton also appears in [[Airship's Revenge]], an optional bonus [[World-e]] level for the [[Super Mario Advance 4: Super Mario Bros. 3|remake]]. Besides Morton, only two other Koopalings are given [[e-Reader]] levels: [[Lemmy]] and [[Ludwig]], and until the Wii U Virtual Console port, Morton was the only one of the three to be present in both the Japanese and overseas releases of the e-Reader levels. In his level, Morton attacks Mario with a new [[airship]] and fights the same way as he did in his original boss battle, complete with wand. After being stomped three times, Morton is defeated once more.

[[File:MortonfromSMW.png|thumb|left|Morton being fought in ''Super Mario World''.]]

Although Morton's official artwork depicts his shell as gray, as with the other Koopalings, his sprites are differently colored: his battle sprites use the green palette intended for the green [[Koopa Troopa]]s and other enemies, while his cast roll sprite uses the teal palette applied to the [[Buzzy Beetle]]s' in-game sprites, and resembling [[Ludwig]]'s palette in ''Super Mario Bros. 3''; although a grey palette closer to his artwork (and his ''Super Mario Bros. 3'' sprite) exists in the game's graphics, for unknown reasons, it is applied to [[Roy]]'s cast roll sprite instead, and none of the Koopalings within gameplay.

Morton appears as a boss once again in ''[[New Super Mario Bros. Wii]]''. In the game's intro, Morton, the other Koopalings, and Bowser Jr. use a giant cake to sneak into Princess Peach's birthday party. They use the cake to capture her and then fly away on their airship with Mario, Luigi, Yellow Toad, and Blue Toad following them from close behind.

Morton is fought in [[World 6 (New Super Mario Bros. Wii)|World 6]] in his tower on a platform with the ends of each side slightly raised up, set in a sea of lava. When Morton sees Mario, he stamps his foot and growls, then begins to fight. Morton's main attack is shooting pink energy blasts that can be targeted in any direction. He can also do a [[Ground Pound]] move similar to that of [[Roy|Roy Koopa]] or a [[Sledge Bro]], that stuns anybody who is on the ground. His pounds last for less time than Roy or a Sledge Bro. Also, Morton's casting speed is extremely slow compared to Roy, but his magic is the fastest in the game, along with Iggy. Whenever Morton is damaged, he jumps into his shell and spin to attack. This attack is faster than the other Koopalings. Fortunately, it can be easily avoided if the player jumps on the raised ground. However, [[Skewer]]s come down from above and land on the two raised platforms, damaging anyone that they hit. Once Morton has been stomped on three times, he retreats to his castle.

In his castle fight, it appears it is going to be very alike to the attacks [[Larry]] used. Then, [[Kamek|Magikoopa]] flies in and sprinkles magic. At first, nothing looks different, except the ground has slightly lowered. Then, Morton uses his immense weight to ground pound and cause the platforms on either side of him to rise up and hit the ceiling. He jumps around and repeat this tactic throughout the battle. Getting squished defeats Mario and company in one hit. It is strongly noted that Morton never uses his magic in the castle fight, and he does not start spinning around as long as the pillars are up.  Also, unlike his tower battle, Morton's Ground Pounds does not stun grounded players during the castle battle.

Unlike in the past titles, players fight Morton after [[Roy]] in this game. Also, in ''Super Mario Bros. 3'', he is the boss of a desert world, while another desert world (though still the second world) is given to Roy in this game, and Morton gets a mountain world instead. In addition, neither Roy or Morton get the cloud world, but it is rather given to Ludwig.

[[File:Morton Koopa Jr. NSMB2 battle.png|thumb|left|The boss fight against Morton in ''New Super Mario Bros. 2'']]

Morton reappears in ''[[New Super Mario Bros. 2]]'', where he is fought similarly to [[Roy]] in the predecessor. He first shows up at the end of {{world link|4|towern2|World 4-Tower (New Super Mario Bros. 2)}}, descending on a chain to taunt Mario. He is then fought in {{world link|4|castlen2|World 4-Castle (New Super Mario Bros. 2)}} and stomps his foot and growl at Mario, like he did in the previous game. In his battle, he creates [[Spike Ball|spiked ball]]s using his wand during the battle and use Ground Pounds to stun all players that are on the floor. Just like the other battles with the Koopalings the player has to jump on him to defeat him. Unlike the other Koopalings, because of the nature of his boss fight with Mario, he does not spend a limited amount of time in his shell upon being stomped, as he requires a pipe upon being stomped on to return to his position. After three stomps, Morton is defeated, leaving the key to [[World 5 (New Super Mario Bros. 2)|World 5]].

[[File:MortonNSMBU.png|thumb|Morton's artwork for ''New Super Mario Bros. U'']]

Morton returns in ''[[New Super Mario Bros. U]]'', its expansion, ''[[New Super Luigi U]]'', and [[New Super Mario Bros. U Deluxe|their Nintendo Switch port]].

After assaulting [[Peach's Castle]] with the rest of the Koopalings and [[Bowser]], Morton's airship is seen in the second world, [[Layer Cake Desert]], much like how he was the boss of the second worlds of ''Super Mario Bros. 3'' ([[Desert Land]], which mirrors how he has once again taken over a desert in this game) and ''Super Mario World'' ([[Donut Plains]]), flying around the desert's castle ([[Morton's Compactor Castle]] in ''New Super Mario Bros. U'', and [[Morton's Lava-Block Castle]] in ''New Super Luigi U''). Like the airships of the other Koopalings, Morton's head is on the bow of his airship, and the deck of the ship is designed to look like his black shell. The stern of his ship and the lids of his cannons are gray, similar to his former shell color from past appearances. Morton's airship has a pair of cannons on each side like [[Roy]]'s ship, albeit stacked on top of each other rather than being placed side by side. Compared to the other Koopaling airships, Morton's appears to be the most robust, and is made out of a darker wood, a reference to his darker skin tone. Once the player enters the boss door of the castle (which leads to an outside section), his airship swoops in from the left, letting off a laugh (which sounds different from his usual voice, with a similar oddity occurring during the airship intros of Roy and [[Ludwig]]) as the player ascends a flight of stairs and jumps into a cannon to board his airship, ending up in his cabin, which has gold-tinted windows, three gold [[Stone-Eye]] statues next to the windows, and, between two chasms, a pit of [[quicksand]] under a bridge.

Like in previous games, Morton stomps his foot once the players enter his boss room, he retains his stunning [[Ground Pound|ground pound]] earthquakes, he slides around in his shell whenever he is stomped on (though he no longer slides around as quickly as he once did), and it still takes three jumps or several [[fireball]]s to defeat him. However, he does not use a magic wand this time. Instead, like [[Wendy]], [[Lemmy]], and Roy, Morton uses a unique weapon, in his case, a giant hammer that appears to be filled with magic. In battle, Morton would ground pound one end of the bridge he and the player are fighting on, causing a giant [[Pokey]] with five segments to be sprung up from the sand pit below and onto the bridge. Morton would then swing his hammer to knock three of the Pokey's segments at the player, either rolling them across the ground, or flinging them in high arcs, before doing a fourth swing that knocks the Pokey's remaining two segments forward in the same way. He then hops across the bridge to the other side to repeat his attack cycle. When defeated, the player is shown on the map repeatedly jumping on Morton's airship, causing it to fly offscreen and eventually crash.

Morton appeared in the interactive Anime adaptation of ''Super Mario World''. On Chocolate Island, he, alongside [[Lemmy]], [[Wendy]], [[Larry]], [[Ludwig]], and [[Roy]], ambushed Mario and Luigi at a fortress. He alongside his brothers fought Mario after Wendy nearly fell into lava, but was stomped by Mario alongside Roy. Although they got up, Mario by that time broke open a red block to get a Cape Feather and sent them flying.

In ''[[The Adventures of Super Mario Bros. 3]]'' and ''[[Super Mario World (television series)|Super Mario World]]'' cartoons produced by [[Nintendo]] and [[DIC Entertainment]], Morton Koopa Jr. was renamed '''Big Mouth Koopa''' (although he was once called "'''Big Mouth Koopa Jr.'''" on the bonus disc of ''The Adventures of Super Mario Bros. 3'' DVD set released by Shout! Factory, making him closer to his original namesake), ostensibly because he was more talk than action. In fact, he talks so much that someone frequently has to step in to stop his speeches (usually [[Bowser#DIC cartoons|King Koopa]] or [[Roy Koopa#DIC cartoons|Bully]]). He once performed a duet called "[[List of The Adventures of Super Mario Bros. 3 songs#Gonna Stomp My Name on the Walk of Fame|Gonna Stomp My Name on the Walk of Fame]]" with [[Wendy O. Koopa#DIC cartoons|Kootie Pie]] in "[[Dadzilla]]."

Aptly, in the ''Super Mario World'' cartoon, he occasionally served as an announcer in three episodes: "[[Send in the Clown]]," "[[Rock TV]]," and "[[The Yoshi Shuffle]]." "The Yoshi Shuffle" marks Big Mouth's last animation appearance.

There are a few physical differences between Morton and Big Mouth: Morton's shell is gray and in the ''Super Mario Bros. 3'' cartoon, Big Mouth's is sometimes colored purple. Big Mouth has much larger eyes and purple eyelids; the star-shaped birthmark on Morton's face is darker around the cheek, while it's just one solid color on Big Mouth. Lastly, Big Mouth is shorter and thinner than Morton, his arms are thinner and a little bit longer, his claws are a little bit sharper and his mouth is light orange instead of pink while his skin is dark orange instead of dark brown. In the ''Super Mario World'' cartoon, however, his mouth and skin return to their original colors.

In ''[[Koopa Capers]]'', Morton and his brothers have their wands stolen by Wendy, who disappears with them shortly afterward, intent on overthrowing their father with her own army, and a super wand she plans to create by fusing her own wand with her brothers'. If Luigi, who had been coerced by Bowser into searching for Wendy, tracks the female Koopaling down to her hideout, Bowser and the male Koopalings, who had been following him, will barge in after the plumber, but decide to stave off punishing Wendy for her mutiny if she helps search for the hiding Luigi. If Luigi had acquired [[Boom Boom]]'s socks earlier in his adventure, he can toss them into Wendy's simmering wand combination potion, which will release fumes that knock the entire Koopa family and their minions out for at least a week. During a point where [[Wendy]] was about to attack [[Luigi]], a small picture that was supposed to show an angry Wendy O. Koopa mistakenly had a picture of Morton instead, even though he was not in that particular scene.

Though Morton does not appear in any versions of the game, his picture is in the [[Mario is Missing! (Super Nintendo Entertainment System)|SNES version]]'s manual. In addition, unused quotes attributed to Morton can be found in the [[Mario is Missing! (PC)|original DOS version]], suggesting that he was originally planned to be encountered in-game as well.

The Koopalings reappeared in ''[[Mario & Luigi: Superstar Saga]]'' where they guard Bowser's Castle. Morton is the second Koopaling to be fought. Defeating Morton raises a platform, allowing the Mario Bros. to continue on towards [[Lemmy]].

Morton reappears in ''[[Mario & Luigi: Paper Jam]]''. He is first seen with [[Iggy]], [[Lemmy]], and [[King Bob-omb]] on top of [[Mount Brrr]], where they shower the land with new enemies and terrain with the help of cannons. In [[Bowser's Castle]], Morton alongside Lemmy command the Papercraft King Boo, which they use to battle Mario & co., but are soon quickly defeated. He is then seen in [[Neo Bowser Castle]], where [[Hammer, Bros!|he attempts to stop the Mario gang]] from obtaining one of the [[Fire Ore]]s needed to create Papercraft Fire Mario. Later on in Neo Bowser Castle, after Mario and co. create the bridge leading to the Bowsers, he appears at the end of the bridge with Iggy and Lemmy, telling them to hurry up and push the button in order summon a large cannon that is aimed at Peach's Castle. At the end of the game, on top of Neo Bowser Castle, Morton is encountered one last time along with the rest of the Koopalings, where he is fought alongside Lemmy and Iggy. In his battle, he can mess up the bros' battle cards, making them do effects that are unknown to the player. After Lemmy and Iggy get dizzy from their own attacks, Morton attempts to get back at the Mario Bros. by lifting Iggy's Chain Chomp and throwing it at them. Mario and Luigi must use Paper Mario as a trampoline to bounce the Chain Chomp back to Morton. Failing to do so results in an instant [[Game Over]]. Successfully bringing the Chain Chomp back to Morton causes damage to him and leave him dizzy, as well as damaging Iggy and Lemmy even more. He remains dizzy until it is his turn to attack again if he hasn't been defeated. After the battle, Morton utters some last words, where he tells Bowser to forgive them for failing to defeat Mario and the others before exploding.

Morton, alongside the rest of the Koopalings, appears as a playable character for the first time in ''[[Mario Kart 8]]'', where he is an unlockable character. This time, he is voiced by [[David Cooke]]. His nickname in a Japanese Nintendo Direct for ''Mario Kart 8'' is ｢無敵のタフガイ」,<ref>{{cite|date=April 30, 2014|url=www.youtube.com/watch?v=C-I4diarSU0|title=マリオカート8 Direct 2014.4.30 プレゼンテーション映像|language=ja|publisher=YouTube|author=Nintendo|accessdate=June 22, 2024}}{{dead link}}</ref> or "Unrivaled Tough Guy'" (localized as the "Mass of Muscle"<ref>{{cite|deadlink=y|archive=web.archive.org/web/20140430145006/http://www.youtube.com/watch?v=flpfRzP2ONU|title=Mario Kart 8 Direct Presentation - 30.04.2014|language=en-gb|publisher=YouTube|accessdate=June 22, 2024|author=NintendoWiiUUK}}</ref> or "Invincible Tough Guy"<ref>{{cite|url=www.youtube.com/watch?v=JbuJZP0_8iQ|author=Nintendo of America|date=April 30, 2014|publisher=YouTube|title=Wii U - Mario Kart 8 Direct 4.30.2014|language=en-us|accessdate=June 22, 2024}}</ref>). His emblem is a white silhouette of his head on a black background in a similar way to Bowser's emblem.

Morton is one of the few characters in the game not to receive any new favorite tracks beyond his debut, with his only default favorite track being {{classic link|N64|Kalimari Desert}}. He shares this distinction with [[Baby Peach]], [[Baby Rosalina]], [[Shy Guy]], [[Dry Bones]] and [[Wendy]].

Morton appears alongside the other Koopalings and [[Bowser Jr.]] as one of the racing opponents in the virtual reality game ''[[Mario Kart Live: Home Circuit]]''. He is seen using his personalized [[Koopa Clown]] from ''Mario Kart 8 Deluxe''.<ref>{{cite|author=Nintendo of America|date=September 3, 2020|url=www.youtube.com/watch?v=f2mCqUSDCJE|title=''Mario Kart Live: Home Circuit'' - Announcement Trailer - Nintendo Switch|publisher=YouTube|accessdate=June 22, 2024}}</ref>

Morton makes his [[Paper Mario (series)|''Paper Mario'' series]] debut in ''[[Paper Mario: Color Splash]]''. In this game, he has stolen the red [[Big Paint Star]]. He is encountered at the top of [[The Crimson Tower]] and acts as the game's first boss. In combat, he uses his magic wand transformed into a large wooden hammer. In the first part of the battle, Morton stays on a pedestal taken into battle by two [[Shy Guy]]s, that also aid him in battle, and retreats on his shell as Mario attacks. While on the pedestal, Morton can attack by slamming on the ground, creating a shockwave that deals 4 HP of damage and inflicts the [[Crumpled]] status effect if not blocked. After the pedestal is blown away by Mario's hammer, Morton directly attacks Mario with the hammer, dealing 8 HP of damage, or by spinning his shell, dealing 12 HP of damage, then, after a while, he calls for two Shy Guys who bring another pedestal in battle and fight with him. Once Morton has received enough damage, he sets his hammer ablaze, drastically increasing its attack power to 48 HP. While this will not defeat Mario if his HP is full, as his max HP at the time is 50, it will most likely defeat him, even if he has taken very little damage previously. The fire can be put out using a [[Fire Extinguisher]] Thing card, that leaves only the grip of the hammer intact, decreasing its attack power to 1 HP. Upon being defeated, Morton alludes to his Master ordering him to steal the red Big Paint Star, causing [[Huey]] to deduce that someone else was indeed searching for the Big Paint Stars. In the Japanese version upon being defeated, Morton instead says 「おかた」, which translates to ''this gentleman'', which was presumably done to avoid giving away that Bowser, or rather, Black Bowser had been behind the theft of the Paint Stars before his formal debut.

Morton appears as a playable doctor under the name '''Dr. Morton''' on ''[[Dr. Mario World]]'', released on October 22, 2020. Dr. Morton is available as a special stage reward in [[World 29]]. Dr. Morton's skill is represented by a hammer strike in stage mode. In stage mode his skill is to changes up to three [[Ice Fan|ice fan]]s and/or [[Bubble Machine|bubble machine]]s into [[Empty Block|empty blocks]], while in versus mode it hides a number of [[virus]]es in the opponent's play area inside [[ice (Dr. Mario World)|ice]] or [[bubble]]s, similar to [[Bowser Jr.|Dr. Bowser Jr.]] and [[Ludwig von Koopa|Dr. Ludwig]]'s skill. The amount of viruses affected by this skill differ based on level, where it is two at level 1 and ten at level 5 (the latter with the added effect of filling the skill meter faster). In stage mode, using this skill when there are no more ice fans or bubble machines left eliminates a random virus or object (if there are no viruses left), although [[capsule]]s cannot be removed by this skill.

Morton cameos in one panel of ''[[Fryguy High Yearbook -- Activity Page!]]'', where he is seen roasting weiners over a [[Fryguy]] with [[Iggy]], [[Lemmy]], and [[Roy]].

[[File:Morton colouring book.png|thumb|The current appearance of Morton in the ''[[Super Mario Bros. Encyclopedia]]'']]

Part of Morton's body could be seen in the sketch made during the redesign of Bowser for the [[Family Computer Disk System]] version of ''[[Super Mario Bros.: The Lost Levels]]'', showing Morton's head being similar to the current one, including the shape of the mouth and the star on the left eye. Differences with respect to the current design include two protruding teeth instead of the current four, two-haired brows instead of the current three-haired ones and two hairs instead of the current three. The claws in the toes also weren't as visible as they currently are. A more notable difference, though, is Morton's size: in the sketch Morton was shown to be about as tall as Toad<ref>As can be seen comparing the {{file link|Bowser Koopalings sketch cropped.png|sketch of Bowser with the Koopalings}} with the {{file link|1993 NCM sizechartA.png|official size chart contained in the 1993 character manual of Nintendo of America}}, which still used artwork drawn by Yoichi Kotabe.</ref> and the body proportions showed him being younger, with the head proportionally being bigger with respect to the rest of the body.

His redesign in ''[[New Super Mario Bros. Wii]]'' marginally changed his appearance, with his shell becoming darker, lined with a white encasing instead of the previous yellow one and featuring light grey rings around the spikes. The pads under his feet also became tan colored just like the pads of the other male Koopalings, while before their color was distinct.<ref>{{file link|Main cast scene SMB3.jpg|Group artwork of ''Super Mario bros. 3''}}, Morton's pad has a different color from that of the other Koopalings.</ref><ref>{{file link|SMWGPB1 Footwear.png|Part of a footprint recognition activity in ''Super Mario Wisdom Games Picture Book 1: Search for the Dragon Coin'' (「スーパーマリオちえあそびえほん 1 ドラゴンコインを さがせ」)}}. Morton's pads are brown instead of tan.</ref> Finally, Morton's irises became visible, revealing their grey color and his tail became visible as well in hand-drawn and artwork illustrations, while previously it was visible only in the sprites of the games. His skin color also was changed from brown to gray, and his size changed from being one of the mid-sized Koopalings to becoming the largest and heaviest of them.

Even though according to the trophy of the fourth installment in the ''Super Smash Bros.'' series Morton is proudly more brawn than brains, similarly to Roy, the Japanese ''Super Mario Bros. 3'' manual implies that he is astute enough to realize whether there are any possible setbacks regarding defeating Mario and can likewise report the information to Bowser. Furthermore, in ''Mario & Luigi: Paper Jam'', when Iggy and Lemmy are eager to fight the Mario Bros., Morton reminds them that they had just wiped out Wendy, Larry, Ludwig, and Roy beforehand. The English translation of the ''Super Mario Bros. 3'' manual instead tones down his thoughtful wording and makes him seem angry, a trait confirmed in the ''Super Mario Advance 4: Super Mario Bros. 3'' Player's Guide, in which Morton is said to be a grouch with a cantankerous personality. Some of his stunts include him flexing his muscles, which indicates that he likes showing off his strength. This trait, along with the preference of brawn over brains, is exacerbated in ''Paper Mario: Color Splash'', in which he boasts about his strength and weight while talking in an unintelligent, loud and simple manner, such as saying ''"MORTON STRONG! MORTON MORE TONS!"''. This is likely imitating his talking style in the Japanese versions of ''Mario & Luigi: Paper Jam'' and ''Paper Mario: Color Splash'', where he doesn't use particles in his sentences. In ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'', Morton is always shouting and often speaks in the third person, but his sentences are more complete and concise. In ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]'', Morton is again depicted as being unintelligent like in ''Minion Quest: The Search for Bowser'', with the Best Fitness Friends jokingly stating that he has 10 brain cells. Regardless of his intelligence or lack thereof, however, he still possesses a strong will like the other Koopalings, as Fawful is forced to use a maximum dosage of his brainwashing spray to bring him under his command, and in ''Bowser Jr.'s Journey'', he resists the effects of Malatone:X long enough to attempt to warn Bowser Jr. to flee from him due to knowing he can no longer control himself. It's also implied that he is not a good cook, as when offering Bowser Jr. a piece of meat, he is reluctant to eat it.

In the ''Mario & Luigi'' series, Morton shows loyalty and protectiveness to his comrades and the royal Koopa family. This is first shown in ''Mario & Luigi: Paper Jam'', with Iggy and Lemmy left disabled from their own attacks on the Mario Bros. that backfire on them, and Morton declaring his intent on avenging them. It is explored further in ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey'', particularly with his relationship with Junior. Upon given the order to look after Junior by Bowser, Morton takes his role as a protector seriously, keeping the Koopa prince happy by feeding him his favorite food, and even one of his skills as First Officer is placing himself in front of Junior, acting as a shield. Morton puts Junior's safety as priority and would fight anyone who has intentions of harming him, even from one of his own siblings, shown when he got in between Roy and Junior when the latter two are arguing.

In ''The Adventures of Super Mario Bros. 3'', all the Koopalings were given names to match the personalities they were given and such was the case with Morton, whose name was changed to Big Mouth Koopa. Big Mouth was extremely talkative, to the point of never seeming to know when to stop talking, which continuously forced [[Roy Koopa|Bully]] to interrupt him. According to the bio on the DVD set for ''The Adventures of Super Mario Bros. 3'', he was also extremely arrogant in regards to his intelligence, as well as exceptionally ignorant regarding the actual facts of the world, and he never accepts responsibility for being wrong, preferring to blame others instead. In addition, he was also known to make cutting remarks, which were severe enough to even make his father cry if directed at him. This talkative trait is also mentioned in ''[[Mario Mania]]'', which states that he is "more talk than action."<ref>''[[Mario Mania]]'', page 52.</ref>

Like Roy, Morton is one of the strongest Koopalings, using his weight to try and crush Mario or paralyze him by using a powerful [[Ground Pound|ground pound]], as in ''Mario & Luigi: Superstar Saga'' and ''Super Mario World'', which even involve him running up the walls and dropping down from the ceiling. His debut appearance in ''Super Mario Bros. 3'' does not involve his earthquake-causing power, however, and he relies on the standard abilities shared with his siblings to fight, such as jumping and shooting magic blasts, although he generally does not use his magical abilities as much as the other Koopalings. In ''New Super Mario Bros. Wii'', he tends to use his magic wand once his enemies are already immobile, and the game also shows that he cannot actually jump very high, unlike earlier depictions. He also has the ability to shoot spiked balls from his wand, as shown in ''New Super Mario Bros. 2''. In ''New Super Mario Bros. U'', he has a magic hammer that he uses to knock giant Pokey segments at the player. Like the other Koopalings, Morton can breathe fire, and in ''Mario & Luigi: Superstar Saga'', he uses some sort of sonic screech against the Mario Bros., which is like Bowser Jr.'s [[Sonic Roar!]] Super Ability from ''[[Mario Strikers Charged]]''. His bio on the Japanese ''New Super Mario Bros. Wii'' website also implies that Morton's strength is dependent on his weapon.<ref>[http://www.nintendo.co.jp/wii/smnj/story/index.html nintendo.co.jp - ''New Super Mario Bros. Wii'' character page] (Click on the blue circle with the arrow to reach the Koopaling page and click on the pictures to see the short bio of each of the Koopalings). [http://www.gamefaqs.com/boards/960544-new-super-mario-bros-wii/52367637 Translation] (Retrieved November 13, 2011)</ref> In ''Mario & Luigi: Paper Jam'', Morton also is demonstrated to have a degree of superhuman strength, as he is shown effortlessly lifting and hurling a massive Chain Chomp at the Mario Bros. in an attempt to avenge Iggy and Lemmy. In ''Super Mario Maker 2'', Morton has the ability to smash blocks underneath him with a ground pound, similar to Bowser in ''Super Mario Bros. 3'', only with the added twist of generating fireballs upon landing.

Despite his strengths, his size also results in him being unable to get up once he is forced onto his back, as evidenced by the ending for ''New Super Mario Bros. 2'', where he ends up on his back as a result of the Koopa Clown Car crashing.

Sprites relating to his planned appearance in ''Super Princess Peach'' imply that he would have inflated himself like a balloon at some point during the battle, as well as spit objects out and charge at Peach.

==Notes==

*Even though Morton is considered the largest and heaviest Koopaling as depicted in ''Mario Kart 8'' and ''Encyclopedia Super Mario Bros.'', his jumps in ''Super Mario Bros. 3'' do not cause the ground to tremble, unlike [[Roy]] and the lighter [[Ludwig]]. He is able to do this in later appearances, though in ''New Super Mario Bros. Wii'', they're still less powerful than Roy's.

*A German ''[[Club Nintendo (magazine)|Club Nintendo]]'' magazine from 1992 erroneously claims Morton is Bowser's oldest son.<ref>{{cite|url=archive.org/details/ClubNintendo1992German/Club_Nintendo_1992_5/page/n31/mode/2up|title=''Morton’s Festung'' from ''[[Club Nintendo (German magazine)|Club Nintendo]]''|date=1992|accessdate=August 11, 2022}}</ref>
