Same with Kefka, though for different reasons. He isn't really the type to let others stop his fun, even if it would ruin the overall plan, as seen with the Emperor at the floating continent.
Ex-Death isn't likely to help any other villain given the whole thing about them being human and him hating them for it.
Ultimecia's plans don't really involve other people very well, at least not for little more then someone to keep meddling do gooders from interfering, so her even teaming with someone is highly unlikely, and wouldn't really offer her much in terms of success.
Zemous, much like Ex-Death, really just hates people. Perhaps then Zemus could come to some terms with Ex-Death and form a pretty bad ass duo? I don't really see any other way main villains that could work out. Though perhaps if I dig through the minor villains.
Like Ultros and Gilgamesh perhaps? :P
