On the Dissidia logo, it looks kinda like a beltbuckle (on his knees are skull-like ornaments/shin guards lol), i'm guessing that's what it could be in the original, too, but for the port I think maybe someone took a little too much creative liberty and made it look like he's carrying around a baby bird. disturbing, but i guess that's what chaos is supposed to be.

i remember seeing another picture of him on a throne by himself, maybe that'll put this to rest.

edit:


i don't know, i think the jury's still out on this one
