Wart

Wart (known in Japan and some Zelda games as Mamu) is an old anthropomorphic frog king and the main villain of Super Mario Bros. 2 and its first model, Yume Kojo: Doki Doki Panic.

Yume Kojo: Doki Doki Panic
Sometime prior to Yume Kojo: Doki Doki Panic, Wart and his army conquered the dimension that lies behind the unnamed storybook that was being read by two children named Piki and Poki, and imprisoned all of its inhabitants. For unknown reasons, Wart stuck his hand through the pages of the storybook and kidnapped the children, pulling them through the book and then having them locked within a cage. The two kids pleaded for help, and then the green dressed monkey Rūsa, presumably their pet, ran out of the room as quickly as he can to go find help, and came across an Arabian family, which consists of Papa, Mama, and their son and daughter, Imajin and Lina. After being informed of the situation, the four heroes jumped through the storybook and embarked on a journey to save the two children, as well as freeing that dimension from Wart's reign. It is unknown if the world of the book and Subcon are the same place or just very similar.

''Super Mario Bros. 2
In Super Mario Bros. 2, Wart had somehow entered Subcon, the land of dreams and had begun a conquest of it. His voice is only heard in Super Mario Advance, which features Charles Martinet, the same voice for Mario. Enslaving Subcon's inhabitants to be his soldiers and also, creating monsters using a device called the Nightmare Machine, Wart's victory was assured. In a desperate attempt to save their world, Subcon's original inhabitants, fairies also called Subcons, contacted the great hero Mario in his sleep to ask for his help. They also gave him a hint to beat Wart. The clue was Wart did not like Vegetables. Mario believing the message to be nothing more than a dream dismissed it and later that day went on a picnic to the park with Luigi, Toad and Princess Toadstool. It was there Mario discovered a door in cave which when the group went through brought them to Subcon.

Mario realizing that the call for help was real convinced the others to help liberate Subcon. After a long journey in which Mario and co. defeated Wart's generals, Tryclyde, Mouser, Birdo, Fryguy, Clawgrip and Robirdo the gang eventually encountered Wart himself. Engaging Wart in combat Mario managed to defeat him by throwing vegetables (which Wart is allergic to) into his mouth. With Wart defeated Subcon was free and after the victory celebration Mario woke up in his bed and was left to ponder if the events that transpired had really happened or if they were all just a dream.

''BS Super Mario USA
Wart once again appeared in all four installments of BS Super Mario USA for Satellaview. BS Super Mario USA is a considered sequel, following his past events. Wart returned to Subcon for one more conquest, attacking the kingdom and its king, also stealing the Gold Statues of his old nemesis, Mario. He also scattered them and giving some of these statues to the generals of the 8 bits. Wart can be found in every tube while being in Subspace, where his room is actually similar to that of the final room of World 7-2 from Super Mario Bros. 2.

"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 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 would eventually reappear 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 worthless droplets of the Apook Corporation. By comparison to "Cloud Nine", in this story, Wart bears a better resemblance to his official artwork appearance.

"Doors to Doom"
Wart made an appearance in the book "Doors to Doom". Dr. Sporis Von Fungenstein had convinced him to convert the denizens of Sub-Con 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.

"Wart steht unter Strom"
Wart was the protagonist in the Club Nintendo comic "Wart steht unter Strom" where he was playing 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: Link's Awakening
Wart made an appearance in the game The Legend of Zelda: Link's Awakening, although here he is referred to by his Japanese name Mamu. Wart was actually helpful to Link in this game, teaching him the third and final song to play on his Ocarina (which opened the way to the last two dungeons).

''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.

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 an over-sized greenish frog with claws and fangs, with a big white 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 crocodile.

Wart's appearance is not always the same. Despite Wart's original looks in Yume Kojo: 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 weared golden chains. However, Wart did had an entirely similar appearance to that of the King Koopa. 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 prideful, rude and menacing, but selfishly persistant. He wants to rule over Subcon, making it as his as its king. As he knows Wart would be refused by the inhabitants of Subcon to accept him, he would attack the land, with the help of the 8-bits to enslave them to become his soldiers and servents. He would probably do that to the rest of the worlds or kingdoms, no matter how hard and risky it may be for him, never giving up until he succeeds, even though he ever fails at it once or more. It was shown in BS Super Mario USA, when Wart returns to "replace" the king of Subcon. Despite he knows himself to be really evil, Wart can have a calm attitude as shown when Link met him, being more of a an ally of the game for Link, unless Mario, Luigi and/or one his friends shows up instead of Link, he will start to fight one of them.

Powers and Abilities
Since Wart is a frog, he possess the abilities that frog has and especially has affinity with water. He spits mutiple bubbles, which seemingly look poisonus and 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 reveiled 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 could not be harmed, not a bomb will injure him, unless a vegetable is thrown at him six times, Wart will lose but has managed to survive all 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 Kojo: 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.

Mario
Since Wart have been interfared in his conquest in Subcon, no one has caused him more problem than Mario himself. Wart consider Mario more of a threat to him more than anyone, considering him as his archnemesis. He defeated many minions of Wart's, with the help of Luigi and his friends. Wart has even a great jealousy more towards Mario, as proven in his return to Subcon in BS Super Mario USA, when he saw many golden statues of Mario by the king of Subcon, as a thanks for defeating Wart like the hero of Subcon. He started to attack Subcon again, stealing the statues, before Mario and friends return to visit the dream land. When impersonating into a good guy, Wart accidentaly insulted Mario and Luigi in Nintendo Comic's Cloud Nine, meaning he could not handle pretending to be good to Mario as he hates him so much.

Birdo
Wart's favorite faithful servant is Birdo, as shown more they are friends instead of king and servant. Wart trusts that Birdo could prevent Mario to come any further to Wart in order to save the world, instead it was to buy Wart and the leader of the 8-bits some more time for preparation for fighting Mario, since she failed so much. Birdo was very loyal to her king, she protected him in the kingdom of Subcon from Mario and friends, though she risked her life for Wart, including the other two species of Birdos, the Red Birdo and the Green Birdo. It is not reveiled that Wart hated Birdo for betrayed him to go to Mario's side (most certainly on Yoshi's).

Luigi
Though Wart has negative relationship with Mario, he also hates Luigi, as he helped his brother to defeat the evil king. Luigi is the second person Wart really despises, the first being Mario, since Wart often sees Luigi with Mario especially in the Nintendo Comics.

Trivia

 * A frog named Wart Jr. appeared in Animal Crossing, Animal Crossing: Wild World and Animal Crossing: City Folk. It is unknown if he is meant to be a relation or an allusion to Wart, as they do not look similar, and apart from Wart Jr.'s latent desire to take over the world, share nothing in common.
 * Oddly, Wart appears in reels B and C in a Master-view toy released during the run of The Super Mario Bros. Super Show!. Despite being labeled as "King Koopa" the character in the Master-view reels is obviously Wart.
 * In Yume Kojo: Doki Doki Panic/Super Mario Bros. 2, Wart can be easily defeated by merely catching a vegetable and jumping behind him (Wart actually starts walking forwards when he is one block away from the wall behind him) and throwing a veggie at his back when he spits a spray of bubbles (he always faced left, no matter where the player is). After enough hits, he would be defeated.
 * In the original Super Mario Bros. 2 (along with its remake on Super Mario All-Stars), when defeated, Wart could still hurt the players if they touch Wart during his defeat. In Super Mario Advance however, he'd go through the players without hurting them when defeated.
 * In Super Smash Bros. Brawl, one of the names that can be gotten from pressing the "RANDOM NAME" button is WART.
 * Being a frog, Wart screams, "Ah, ribbit" every time Mario or his friends throw vegetables in his mouth. However, this only happens in Super Mario Advance.
