Ganon is a non-playable boss character in the fighting video game, M.U.G.E.N Trilogy. He was confirmed along with the other bosses on July 4, 2018. His first appearance was as the beast in the original The Legend of Zelda game, although it was misspelled as Gannon in-game. The villain made his first humanoid appearance as Ganondorf in The Legend of Zelda: Ocarina of Time. Since then, the name "Ganondorf" has been used to refer to his Gerudo form while "Ganon" is used for his monster form.
Ganon was originally introduced in the original The Legend of Zelda game. Here, he was established as a power-hungry monster who had kidnapped Princess Zelda for her piece of the Triforce, but was destroyed by Link at the end of the game. Since then, collecting the Triforce and conquering Hyrule has usually been Ganon's main goal in the series. He has appeared or been mentioned in nearly every Zelda game, with four exceptions: Majora's Mask, Four Swords, The Minish Cap and Spirit Tracks.
Ganon's appearance has changed over the course of the series. In his first appearance in The Legend of Zelda, he appears as a bestial, porcine demon with turquoise skin (though it will change to red at one point, which is the cue to hit him with the Silver Arrow), while in The Legend of Zelda: A Link to the Past, he has blue skin and turns silver when weak to the aforementioned Silver Arrows. Ocarina of Time, which first showed Ganon's human appearance as Ganondorf, depicts his bestial Ganon form with similar articles of clothing as Ganondorf, dark green fur, a red mane, and large curved horns. The Legend of Zelda: Twilight Princess, in a departure from previous games, features a quadrupedal Ganon for the first time.
