Bahamut rwas renamed "Neo" at one point?Was he named after Neo from the Matrix because he's practically all powerful or did square forget that he's been around since FF1 and decide that they were adding a new (Neo) character of some kind?
Neo Bahamut was in ff7 as well as Bahamut Zero and Bahamut. He is one of the three bahamut versions on the game, and I don't think he was named after neo from the Matrix.

Anyway I voted for Doomtrain because he is the best Summon in all of Final Fantasy in my opinion.
