@Maynard:
Well true but I remember someone posted a color which is pretty similar to his suit. Well thats the only reason I though he would be it anyway. And I still think that guy isn't momonga. He looked like this.
Anime screws up many times, so just use the manga. It's the safest.
EDIT: also, him being in that panel doesn't exclude him from being an Admiral. Other things may, but that one doesn't.
