Ultimate Alien
Jimmy first appears in Fame when Ben finds out that Jimmy has been posting things and a sent out video about him and his aliens on a website that finally showed the world that Ben has the ability to turn into aliens, as he thought Ben would like the fame and money, but Ben ended up being both liked and hated by the public.
