Wart

Wart (known in Japan and some Zelda games as Mamu) is an old anthropomorphic frog king and the main antagonist of Super Mario Bros. 2 and its base game, Yume Kōjō: Doki Doki Panic. He is the leader of his troop known as the 8 Bits, and one of the evil arch nemesis's of Mario. Wart's information in the game's instruction booklet says, "He is the most mischievous of all in the world of dreams. He created monsters by playing with the dream machine."

''Yume Kōjō: Doki Doki Panic
In Yume Kōjō: Doki Doki Panic, Mamu's true origins lie in the Tale of the Dream World of Muu. In the original storyline, Mamu took control of the Muu people's Dream Machine to produce monsters and mayhem. However, the Muu people knew of his weakness to vegetables and fought him by hurling vegetables at him. Mamu surrendered, bringing peace back to the Dream World. In the "real" world, the green-dressed monkey Rūsa gave the storybook to the twins Piki and Poki. Towards the end of the book, the twins quarreled and tore 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, fulfilling his dream of conquering Muu. The two kids pleaded for help, Rūsa ran out of the room as quickly as he could to go find help and comes across an Arabian family, which consists of Papa, Mama, and their son and daughter, Imajin and Lina. After being informed of the situation, the Arabian family jumped through the storybook and embarked on a journey to save the two children and free Muu from Mamu's reign.

After all of his army and leaders has been defeated by the Arabian family when traveling through the world, Mamu engages the family in battle in the castle. Mamu can spit five bubbles at the four heroes and can destroy the vegetable projectiles produced by the machine of his room. Conventional attack methods are ineffective against the tyrannical amphibian. The Arabian family has to throw vegetables in his mouth when it's open, defeating him after four hits. After Mamu's defeat, the inhabitants are saved, completing the story. The two kidnapped children are rescued from their cages and return with the Arabian family back to their world, where the game ends.

''Super Mario Bros. 2
Wart was renamed and made his first official appearance in the Mario series with Super Mario Bros. 2. In this version, Wart appeared in Subcon, the world of dreams, and begins a conquest of it. Enslaving Subcon's inhabitants to be his soldiers and also creating monsters using a device called the Nightmare Machine, Wart's victory is seemingly assured, as it expands greatly, the magnitude of his army, the 8 Bits. With the 8 Bits all across the world, he had his leaders in each of the lands of Subcon. In a desperate attempt to save their world, Subcon's original inhabitants, the fairies (also called Subcons), contact the great hero of the Mushroom Kingdom, Mario, in his dreams to ask for his help. They also give him a hint to beat Wart, which is his distaste for Vegetables. Mario, believing the message to be nothing more than a strange dream, dismisses it and later goes on a picnic to the park with Luigi, Toad, and Princess Toadstool. Mario then discovers a door in a cave, leading to Subcon.

Mario, realizing that the call for help is real, convinces the others to help him liberate Subcon, the inhabitants and the Subcons. After a long journey in which Mario and friends defeat Wart's 8 bits and the leaders, Tryclyde, Mouser, Birdo, Fryguy, Clawgrip, the Birdo species, and Robirdo, saving some lands of Subcon, the heroes eventually encounter Wart himself in the castle of Subcon. Engaging Wart in combat, Mario has to defeat him by throwing vegetables six times into his open mouth when he spits many bubbles. He also has the same behavior and abilities in Yume Kōjō: Doki Doki Panic, and became more resistant at vegetables. With Wart defeated after swallowing too many vegetables (for him that is), Subcon is free from Wart's reign, including fairy inhabitants of the world. Wart is seen one last time during the victory celebrations where he, bloodied and injured, was crowd-surfed by the recently freed Subcons, eventually resulting in a huge off-screen beating on him (implied by the swirls and stars as he disappears offscreen). After the victory celebrations, Mario wakes up in his bed and is left to ponder if the events that transpired really happened or if they are no more than products of a dream, then continue sleeping.

''Super Mario Advance
In Super Mario Advance, the remake of Super Mario Bros. 2, Wart's new voice is now heard which features Charles Martinet, who also voices Mario and Luigi. In this game, Wart spoke clear sentences such as, "I am the great Wart!" and "Ah, ribbit!". He even has a new leader, Robirdo.

''BS Super Mario USA
Wart once again appears in all four "Power Challenge" installments of BS Super Mario USA for Satellaview. BS Super Mario USA is a follow up which occurs after the original Super Mario Bros. 2. Wart returns to Subcon with the 8 bits and leaders for one more conquest in the world, overthrowing the king and apparently also stealing golden statues of his old nemesis, Mario. Wart can be found in every tube in Subspace, where his room is actually identical to that of the final room of Subcon's Castle (World 7-2) from Super Mario Bros. 2. He possesses the same behavior when fighting him, and the Nightmare Machine produces vegetables like the last time. In the end, the 8 bits still lost again against Mario, with Luigi, Toad and Princess Toadstool. With this, Wart's antagonism was seemingly gone for good.

Like Mouser and Birdo, his portrait will periodically appear on the screen as he casts randomly a spell on Mario. This could be stopped only when Princess Toadstool aggressively interrupts it. Like all the major characters in this version, he is voiced, though due to its broadcast nature very little of the dialog and narrative (if substantial) is considered either lost or obscure.

"Cloud Nine"
Wart made an appearance in the Nintendo Comics System issue Cloud Nine. In the comic Wart, disguised as a bed salesman, abducts King Toadstool 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. Wart looked more like a crocodile than a frog in the comic.

"Duh Stoopid Bomb!"
Wart was also briefly mentioned in a later Nintendo Comics System story entitled Duh Stoopid Bomb!, where his name is seen on Wooster's list of people who think King Toadstool is dumb.

"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. By comparison to Cloud Nine, in this story, Wart bears a better resemblance to his official artwork appearance. Wart also appears to have some resemblance to a crocodile/alligator.

''Nintendo Adventure Books
"Right here in the Land of Outrageous Dreams. It's a most excellent dream, Dude. Far superior to that conquer-the-world stuff. Now I dream of skating the most radical inclines possible. That short fungus doctor dude helped me turn Subcon into this raucous skate park. Gnarly, don't you agree?"

- Wart

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 playing a Game Boy. He tries to trade a garage door opener for one of their hats.

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".

''Club Nintendo
Wart is the protagonist in the Club Nintendo comic "Wart steht unter Strom," in which he plays Game Boy and got involved in a fight with Mario due to him simply throwing the batteries of his Game Boy away. Wart looked just like a smaller version of Bowser in this comic. This may be considered as a mistake, since later appearances of him in the magazine refer to him as Bowser.

The Legend of Zelda series
Wart made an appearance in the Legend of Zelda series, namely The Legend of Zelda: Link's Awakening, along with other Nintendo characters from the Mario series. In his appearance, he is called Mamu, his original Japanese name. Wart resides in the pond beneath the Signpost Maze, with his two frogs. Instead of being an antagonist, he plays a role of a supporting character who helps Link in his quest by teaching him one of the ocarina songs, the Frog's Song of Soul for 300 Rupees. Once he has taught Link the song, he is never seen again.

''Mario Superstar Baseball
Wart was mentioned in Shy Guy's biography in Mario Superstar Baseball; however, he was directly never seen in the game.

''Super Paper Mario
In Super Paper Mario, Wart is featured in a product that Francis owns and wants more of called Cyborg Wart. It is said that in this comic book, in contrast to his major appearances as an antagonist, he is a protagonist.

Physical Description
Wart's appearance is very similar to that of Bowser and Prince Froggy (though Prince Froggy appeared 9 years after Wart). He is the first one of the frog race starting in Super Mario Bros. 2 before others, regardless his first appearance in Yume Kōjō: Doki Doki Panic. Wart is an over-sized greenish frog with claws and fangs, with a big white round belly. Wart has no eyebrows, though he has big eyes and black little pupils. He has four claws on each of his hands, while he had two on each of his massive feet. He wears a big blue cape, a big kingly golden crown, a big necklace with golden bracelets. His arm is large but not as large as his huge legs. To look more menacing, Wart had to look like a bit more like a crocodile.

Wart's appearance is not always the same. Despite Wart's original looks in Yume Kōjō: Doki Doki Panic, Super Mario Bros. 2, Super Mario All-Stars and BS Super Mario USA, Wart first looked more like Bowser from Cartoons in the Nintendo Comics, with a more crocodilian face, a somewhat tail similar to that of Bowser's himself. His belly is exactly the same as his, and he wore gold chains. However, Wart did had an entirely similar appearance to that of the King Koopa, his appearance was a combination of frog, crocodile and turtle. Secondly, Wart was more like a toad and was less bigger in The Legend of Zelda: Link's Awakening, his artwork is identically to a toad.

Personality
Wart is known to be proud, rude, menacing, selfish, and persistent. His greatest desire is to conquer the dream world Subcon. More likely than not, he would not be satisfied and would take on the rest of the universe. He does not stop, even if he is defeated. This was shown in BS Super Mario USA, when Wart returns to "replace" Subcon's king; in other words he tried again to conquer it, but was defeated by Mario. Yet, Wart is known to be very jealous of Mario. After his conquests on Subcon, Wart can have a calm attitude as shown when Link met him. Instead of conquering Kolohint Island, Wart spent most of his time traveling throughout the world and assisting Link on his quest. He even has his two Frof Choir with him.

Powers and Abilities
Since Wart is a frog, he possess the abilities that any frog has and especially has affinity with water. He spits multiple bubbles, which seemingly look poisonous and is his signature move, however, his usual abilities. He can choose to shoot many water bubbles or spit a long breath of water. Wart can also use magic, and put a curse on someone, as revealed that the curse he put on Mario during his sleep did not work according to the Instruction Manual of Super Mario Bros. 2, but he can put a spell on an entire world. Wart is invincible; he could not be harmed, not even a bomb will injure him, unless a vegetable is thrown at him six times (four times in Yume Kōjō: Doki Doki Panic), Wart will lose but has managed to survive all of this many times of defeats. He did fallen down after defeating him in BS Super Mario USA, he caused an earthquake, which shown he could shake the ground too because of his strength. In Yume Kōjō: Doki Doki Panic, Wart is able to struck his huge hand to the outside world, as shown to be very huge in the outside world, it also prove that he could travel from world to world, wherever he wishes to, including in The Legend of Zelda: Link's Awakening.

Trivia
