No, you can not I am an owner of this game. It only has Rath, Armadrillo, Terraspin, NRG, Ampfibian, Swampfire, Humongosaur, Big Chill, Echo Echo, Spider Monkey, Ultimate Swampfire, Ultimate Humonosaur, Ultimate Big Chill, Ultimate Echo Echo and Ultimate Spider Monkey. Not Benwolf, Benmummy or Benviktor. Sorry. They should make Ultimate forms of every alien. Hope this was useful.
