I FOUND IT! (Spoiler)

Okay, okay. For those of you who are waiting for the GCN version, and want to know what Ganondorf looks like, well, here he is!

Just scroll down. I also found the story behind him.

In essence, Ganondorf is the one behind all the events of Twilight Princess. After he was sealed away in the Dark World, the Seven Sages released him to await execution in Arbiter's Grounds, a prison in Gerudo Mesa. The Dark Lord was ritualy chained to a giant rock and impaled by a blade of light. The Triforce of Power gave him power to survive execution and break free from the chains. He slays a sage, and while charging at the others, the Twilight Mirror was activated, sending him into the Twilight Realm and reducing him to energy matter.

Posing as a god, Ganondorf gives Zant his powers in exchange for freedom from the Twilight Realm. He is the final boss, where you fight him in multiple forms. You battle him, along with a possessed Zelda, in Hyrule Castle. Once exorcised from Zelda, Ganondorf turns into a massive boar-like Dark Beast Ganon. First, Link must simply fire arrows at him, but after he must turn into his lupine form, requiring Midna to topple Ganon so that Link can successfully attack him. The battle concludes with a close-range duel between Link and Ganondorf on Hyrule Field near the Bridge of Eldin. In the end, Ganondorf is impaled with the Master Sword, losing the Triforce of Power that maintained his life. A scene then shows Zant's neck snapping (apparently by his own hands), though the meaning of this is unknown. It is speculated that this is because since Ganondorf gave Zant his powers, Zant is connected to him. When Ganondorf died, Zant went down with him.
