I have an idea.
Earlier, Gilgamesh said he had buisness with Odin.
why won't we let the party encouter Gilgamesh when he is just arguing with Odin who has the most power, like:
Gilgamesh: I am stronger than you! I have 4 swords!
Odin: At least i don't die in FF5.
Etc.
Edit: Eeuh, well maybe a little more serius, but it is an idea...
