Smash Champion

Eh, I'm really hoping he's not in Skyward Sword.
As Spire pointed out earlier, the lore from Ocarina of Time of "...born every 100 years..." stands a role in this matter, unless Nintendo honestly just doesn't care about that(I know Miyamoto is sort of limbo these days).
Now, I'm not one for huge conspiracy theories, or hopeful plots of the game, but it would be very intriguing to me if the main plot of the game was Ganonorf himself being born in the first place. Think about the Gerudo tribe. Before Ganondorf/Link in OoT(to our knowledge of their existence), all female(detest men I believe as well). I mean, unless it's a Virgin Mary story, that wouldn't happen. *Don't go out on me on this if thing's are..you know*
I think you guys could understand where I'm getting at there, correct? Like I said, I don't want to go deep into a plot that doesn't need dwelling into to begin with. Of course, Nintendo could through a big *** curveball, and have the Gerudo tribe and Ganondorf 100 years before again. To be honest though, I want someone as enigmatic as Skull Kid in Majora's Mask. He was excellent.
Eh, don't take this too seriously if not needed. /rant
