Most of the Legendary Pokémon which wouldn't otherwise fit into any type are Psychic types. Deoxys, Latios, Latias, Lugia are all Psychic types. Alien X can also be Psychic type much like these Pokémon. Another option could be Normal type with the ability multitype like Arceus. That way he could be any type he wants to.
