Square Enix has updated the official Final Fantasy XIII web site with new information and pictures on two gestalt modes. First up is Bahamut, Oerba Yun Fang’s summon. Longtime FF fans will remember Bahamut as one of the most potent summons around. In FFXIII, it becomes a…chocobo/bat machine…with a little AT-ST thrown in.
Sazh Katzroy’s summon is just as ridiculous.
Chocofro wields the power of Brynhildr, which turns into motorized tricycle with a carriage top and ribbons (at least, I think they’re ribbons).
Gestalt mode is giving me a headache.
