Wart (known in Japan and in The Legend of Zelda: Link's Awakening as Mamu) is the main antagonist of Super Mario Bros. 2. He is the leader of a gang known as the 8 bits and his major appearance centers around his efforts to conquer Subcon, a land of dreams. Wart's information in the original instruction booklet states, "He is the most mischievous of all in the world of dreams. He created monsters by playing with the dream machine." He created all of the game's monsters, which are also referred to as his "moppets."
Yume Kōjō: Doki Doki Panic
In Yume Kōjō: Doki Doki Panic, Mamu's true origins lie in the tale of the dream world, Muu. In the original storyline, Mamu had taken control of the Muu people's Dream Machine, producing monsters and mayhem. However, the Muu people knew of his weakness to vegetables and used them to force a surrender, bringing peace back to the dream world.
In the "real" world, the green-dressed monkey Rūsa gives the storybook to the twins Poki and Piki. Towards the end of the book, the twins quarrel and tear out the final page of the story, thus erasing the book's ending. Freed, Mamu pulls through the pages of the storybook and kidnaps the two children. The two kids pleaded for help, and Rūsa hurries away. The family, which consists of Papa and Mama and their son and daughter, Imajin and Lina, jumps through the storybook and embarks on a journey to save the two children and free Muu from Mamu's reign.
One by one, Mamu engages the family in battle in the dream factory. Mamu can spit five bubbles at once and can destroy the vegetable projectiles produced by the Dream Machine. Conventional attack methods are ineffective against the tyrant. The family has to throw vegetables in his mouth when it is open, defeating him after four hits. After Mamu's final defeat, the inhabitants are saved, completing the story. The two kidnapped children are rescued from their cages (with the key being thrown at the cage while Mamu was being beaten offscreen to a pulp by the Muu people) and return with the family back to their world, where the game ends.
Super Mario series
Super Mario Bros. 2
When Doki Doki Panic was released overseas as Super Mario Bros. 2, Mamu's name was changed to "Wart". When the international version of Super Mario Bros. 2 was released in Japan as Super Mario USA, the original name of "Mamu" was used, but all other plot-related changes remained.
Like in Doki Doki Panic, Wart used the hijacked Dream Machine and his army (known as the 8 bits) to conquer Subcon. Instead of fighting him, the natives of Subcon make contact with Mario through one of his dreams, pleading for him to save them and telling him about Wart's weakness: vegetables. The next day he, Luigi, Princess Toadstool, and Toad discover a door to Subcon and decide to save the dream world from Wart.
The battle with Wart is identical, except Wart requires six vegetables to be defeated. After his defeat, Wart is seen one last time during the victory celebrations, being crowd-surfed across the screen by the now-freed Subcons. As he disappears off the screen, the Subcons pummel him one last time. During the cast roll, Wart appears laughing at the very end.
Super Mario Advance
In Super Mario Advance, the Game Boy Advance remake of Super Mario Bros. 2, Wart is given dialogue, spoken by Charles Martinet, with Wart's voice bearing resemblance to his performance of Wario. In this game, Wart spoke clear sentences such as, "I am the great Wart!" and "Ah, ribbit!". The 8 bits is also given another major member, Robirdo. One minor difference is that after he is defeated, Wart's body becomes intangible to the player, unlike in the original Super Mario Bros. 2 (and its port in Super Mario All-Stars), where the player can still take damage from contact with his defeat animation.
The remake expands on Wart by implying he is capable of casting magic. This is shown in cutscenes prior to fighting Fryguy and Clawgrip, bosses that are initially seen in a weaker form before bubbles that resemble Wart's arrive to envelop them. The bubbles transform his minions into their massive forms.
BS Super Mario USA
Wart once again appears in all four "Power Challenge" installments of the Satellaview title BS Super Mario USA, a follow-up of the American version of Super Mario Bros. 2. In this game, it is shown that after his defeat, Wart and his crew escaped to another dream and laid low for a while; they eventually return and attack Subcon once more, forcing its king into hiding and moving him to summon Mario, Luigi, Toad and Princess Peach once more.
Wart can be found in every jar in Subspace, where his room is actually identical to that of the final room of the factory (World 7-2) from Super Mario Bros. 2. He possesses the same attacks and is defeated the same way as in his earlier appearances. Like all the major characters in this version, he is voiced but his picture does not appear on the top right when he talks. On certain intervals, Wart's harmful bubbles will float up from the bottom of the screen.
Super Mario Maker 2
Although Wart does not appear as a usable course element in Super Mario Maker 2, his original sprite appears briefly when the Final Boss sound effect is played while wearing the SMB2 Mushroom, just as Birdo's appears with the Boss Music sound effect.
Nintendo Comics System
Wart made an appearance in the Nintendo Comics System issue "Cloud Nine." In the comic Wart, disguised as a bed salesman, abducts the Mushroom King and also tries to flood the Mushroom Kingdom. Notably in this story, Mario mentions Wart had abducted the king on at least one previous occasion.
"Duh Stoopid Bomb!"
"Tanooki Suits Me"
Wart eventually reappears in the comics in the story "Tanooki Suits Me," in which Bowser plans to sell him pieces of artwork that he had stolen from the Mushroom Castle's Royal Art Gallery for a huge profit. However, a disguised Mario is stolen along with the artwork and, upon discovering Bowser's plot, manages to fool Wart into believing that the artwork is nothing more than worthless droplets of the Apook Corporation. In comparison to Cloud Nine, Wart here bears a closer resemblance to his official artwork appearance.
Nintendo Adventure Books
Wart made an appearance in the Nintendo Adventure Books book Doors to Doom. Dr. Sporis von Fungenstein had convinced him to convert the denizens of Subcon into surfers, and when the Mario Brothers meet Wart, he is friendly and welcoming, munching on a corn dog and playing a Game Boy. He tries to trade a garage door opener, which is a required item for the book's good ending, for one of the brothers' hats. However, Wart is still a potentially dangerous figure; making the wrong choices when trying to enter his lair results in Game Overs, either by being assaulted by Wart on his skateboard or being exposed to dangerously loud rock music. Also, when trading with him, offering him Luigi's hat (which is too small for him) ends up with Wart ripping the hat and a furious Luigi insulting him in response. If Luigi follows up on his anger by attacking Wart with vegetables, Wart counters by spitting them back and running the brothers down with his skateboard, also resulting in a Game Over.
In the later book Dinosaur Dilemma, Wart has a cameo as one of the guests invited to the party Bowser is holding at his Dinosaur Island Castle, in honor of being chosen as the recipient of that year's Snowbell Prize. The text introduces Wart as "the king of the Land of Nightmares".
The Legend of Zelda series
Wart, under his Japanese name Mamu, makes an appearance in the Game Boy game The Legend of Zelda: Link's Awakening, its Game Boy Color re-release, and its Nintendo Switch remake (making his first 3D-modeled appearance in the Nintendo Switch remake). He lives in a pond beneath the Signpost Maze on Koholint Island, which, like Subcon, is a dream land. However, unlike in the Mario game, Wart is not an antagonist in Link's Awakening, and actually helps the hero, Link. In exchange for 300 Rupees, Wart teaches Link a song on the ocarina, the "Frog's Song of Soul", which is required to revive the Flying Rooster and to access the final main dungeon. After teaching Link the song, Mamu is not seen again.
Super Smash Bros. series
Wart was referenced in Super Smash Bros. Brawl, in that "WART" was one of the randomly generated names offered to players.
Wart appears as an Advanced-class Grab-type primary spirit in Super Smash Bros. Ultimate. When equipped, it simply increases the fighter's power. In World of Light, the spirit can be encountered on the Light Realm map. The spirit's puppet fighters are King K. Rool and Peach, and the battle takes place on the Battlefield form of the Skyworld stage. "WART" also returns as a randomly selected name.
Other appearances, cameos, and references
Wart never appeared in The Super Mario Bros. Super Show!, though many of his characteristics were given to King Koopa instead. Of further note, an early promotional posterMedia:SMBSSHotdogPoster.jpg featuring several highly off-model enemies features a large frog monster wearing a necklace among them, possibly intended to represent Wart; however, it also is purple, has large lips, no clothes other than the necklace, and wields a spear. In addition, Wart, mislabeled as "King Koopa," appears in reels B and C in a Master-view toy released during the run of The Super Mario Bros. Super Show!.
In the artwork for the Super Mario Bros. pinball machine, Wart is shown on the castle in world 6, presumably holding Luigi captive despite the former not appearing in Super Mario World, the game that the pinball machine is based on, as well as the fact that Luigi is never at any point held captive during said game.
In Paper Mario: Color Splash, Wart is mentioned by a yellow Toad at Sunglow Ridge. Said Toad states that he saw Wart in a dream, only to ponder whether it really was a dream, referencing the events of Super Mario Bros. 2.
Wart is a large, green frog with a big white round belly, a general body shape resembling most frogs, a vaguely crocodilian snout filled with large blunt white teeth, and large claws on his two-toed feet and four-fingered hands. The Nintendo Comics System depicts him with scales and even a spiked tail (similar to Bowser), giving him a closer resemblance to a crocodile or alligator, rather than a frog. He is typically depicted as wearing a blue cape (white in-game, and light brown in remakes). He also wears a crown with an emerald on it, a large diamond-shaped ruby set in a gold pendant on a gold necklace, and gold bracelets.
Very little of his personality has been revealed beyond the fact that he is willing to cause mayhem and destruction in order to achieve his goal of ruling Subcon. However, BS Super Mario USA does suggest that he is cunning and patient enough to bide his time between attacks, and the fact that he stole all the Mario statues may indicate a spiteful side to his personality.
