I didn't because that would have been the dumbest plot event ever in a Zelda game.
He's clearly an ancestor of the Gerudo tribe, though.
Yeah, but I don't see Groose becoming villainous. Gerudos aren't evil, just Ganon. I would like to see how the tribe got started, though. Maybe explain the Great Deku Tree, Zoras, Gorons, and Mogma transition to OoT too.My bet is that the 3DS game is going to be something along those lines.
A generation or two after SS, there's a fair to celebrate the anniversary of the founding of Hyrule, big statue of Groose and a tiny statue of his flunkies next to it, then some villain does a villainous thing and ~adventure start~.
