Ganon (ガノン) is the main antagonist of The Legend of Zelda series. 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" (alternatively Beast Ganon or Dark Beast 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 is physically present or otherwise referenced in nearly every Zelda game, with four exceptions: The Legend of Zelda: Majora's Mask, The Legend of Zelda: Four Swords, The Legend of Zelda: The Minish Cap, and The Legend of Zelda: 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.
While Ganon does not physically appear in The Legend of Zelda: Skyward Sword, his spiritual ancestor, Demise, appears as the main antagonist and final boss. Upon being defeated, Demise warns that he will be reincarnated for eternity along with the blood of the goddess (Zelda), and the spirit of the hero (Link), and all three will be forced to battle for the fate of the world. One of these incarnations would be Ganondorf in Ocarina of Time. Another incarnation would be Ganon from The Legend of Zelda: Four Swords Adventures, who is related to the previously mentioned Ganon in name only.

Ganon made his debut in the Super Smash Bros. series as Beast Ganon, the Final Smash of Ganondorf in Super Smash Bros. Brawl and Ganondorf in Super Smash Bros. 4. Ganon is modeled after Dark Beast Ganon from Twilight Princess to match Ganondorf's design from the same game.

As a boss
Ganon appears as a boss in both Classic Mode and in World of Light; in the latter, he is fought in the center of the Sacred Land sub-map. He is fought in an arena resembling the ruins of Ganon's Castle in Ocarina of Time, with Ganondorf standing amid the ruins before transforming into the Demon King. Like Ocarina of Time, he can only be damaged by attacking his tail: if the tail is hit hard enough, Ganon will be stunned and allow the player to deal further damage, with his head becoming another weakness. Along with standard sword slashes and a charge attack similar to the Final Smash, Ganon uses several new attacks:
When defeated, Ganon will wildly flail his swords and roar, similar to his defeat animation in Ocarina of Time, before exploding.
The Fighters that are assigned to fight Ganon in Classic Mode are Link, Young Link, Toon Link, Zelda and Sephiroth. Usually, Calamity Ganon Battle - Second Form plays during the battle, but Death Mountain plays in Zelda's Classic Mode.
