This is a sad, sad thread. Kh continues to be a blight on Final Fantasy.

Neo Exdeath: I am Neo Exdeath... All memory, existence, and dimensions...All that is shall be returned to nothing.

Neo Exdeath was going to erase universeS. Plural. So the mighty Mansex's universal powers really aren't that unfathomable.

And how about Ultimecia?

"Ultimecia, transformed to absorb all time and space. Absorbing all existence as we speak."

Why she's sucking in the entire universe into herself.

It should serve as a mark of how low KH is that I'm supporting Ultimecia over it.

So, no, Sora can't beat every FF character. I doubt he could beat even lesser villains like Sin.
