"Five years into the future" (Why?)

[Etheos]

This is true lol. What would be Odin's decision for stopping Bahamut though? Or did his mere presence cause Bahamut to go "oh sh#t, time to book it"?

I can't see Odin honestly defeating him. They made Bahamut too bad ass to have a challenger. It would have to be many, or even have Diablos dropping in for a visit (kidding of course).
