Earlier today I was doing a New Game + of 5.4/5.5 and I have a question I can't seem to find an answer to.

"Why Does Bahamut look like that"

All other members of the first brood we have seen are very serpent like but Bahamut reminds me more a T-Rex with those stubby arms.

Did his summoning make him look funny and that's just his primal form or did he really look that much different from his siblings and sire?
