Now that I think about it, Ghost/Fighting type suits him the most. Alien X is omnipotent and hence cannot be harmed by a "normal" being. Since he is part fighting he is strong against dark types. He is still vulnerable to other omnipotent beings, a similarity to ghost types who are weak to themselves. Since Ben can get outsmarted by someone, Alien X has the Psychic weakness.

Upgrade should be Electric/Ghost type because of his similarity to Rotom, both being able to possess machinery.
