I would say this isn't what I want from Bioware... but I haven't enjoyed the last handful of Bioware games I touched (Dragon Age 2-3, ME 3 and Andromeda)... so... maybe I just don't want Bioware games any more.
Nominations: Marle from Chrono Trigger. Slaps her ass as part of a special move. Need I say more?
Dead or Alive, literally any female character. I can't even start making this decision, but it should be up on the board.
As for disagreements, and arguments why: I think the plot importance of Meryl Silverburgh's butt raises it above both Mistral and Old Snake, as you literally have to compare butts to find her. Snake is basically the pioneer of fingerprinting, but for butts.
I also think that Wario deserves mention for the Mario franchise, though it's admittedly a ... different direction than most of this list goes.
