Ganondorf

Ganondorf, also known as Ganon in his most powerful form and Agahnim, is the main antagonist of The Legend of Zelda series and the reincarnation of hatred itself.

Ganon
Ganon is the ultimate incarnation of Ganondorf, being a large brutish anthropomorphic boar. He is considered the demonic alter-ego of Ganondorf, and as such is extremely powerful, being one of Link's most dangerous foes.

Agahnim
Agahnim is a dark wizard, actually being a complete copy of Ganondorf only with a different physical appearance. This version of Ganondorf is the main antagonist of The Legend of Zelda: A Link to the Past.
