If you could choose to be a videogame villain, which one would you be? You ofc know you're gonna lose and all, but which one would you choose purely for the fun they must be having, etc..?

Definitely Gilgamesh from the Final Fantasy series. He was banished to a rift between dimensions in his debut games and ever since then he pops up as an easter egg in later games in the series, with his dialog implying that yes, this is the same guy as in the other games. also he has a kick-ass battle theme
