Given that we've already gotten Bahamut and are getting Ultima, I was just curious as to what other stuff could work as an Ultimate fight. Is it exclusive to just major battles? If so, I can't imagine anything from ARR beyond Ultimate Cloud of Darkness and Ultimate Tribunus + Gaius.

If it could be anything that's popular, though, maybe Ultimate Edda could be a thing, even if I'd find that a little silly.

Was just curious as to what people thought were likely Ultimate fights that could occur.
