Eternal Dragons

One thing that has lasted most of the Final Fantasy series (apart from the name Cid), is Bahamut. And from there, Bahamut has been a constant wonder, usually the most spectacular esper, summoned beast, Guardian Force, etc... And for the first time, Final Fantasy VII had three versions of their infamous dragon: Bahamut, Neo Bahamut and Bahamut ZERO. Each one more kick-ass than the next.
