Can Ben 10,000 use Ultimate Aliens?
After discovering this transformation, Ben 10,000 has not needed to physically transform into any of his actual alien forms for years. Though he could still turn into regular and Ultimate aliens, he preferred using Ultimate Ben for quicker access to the aliens’ powers in combat. Ben 10: Omniverse XLR8 is a playable alien in the game (only by 11-year-old Ben; only playable by 16-year-old Ben on DS and 3DS).The Omnitrix is neither able to accept the evolved DNA of Ultimate forms [DJW 5] nor be transformed into an Ultimatrix by a Polymorphic Crystal. Because of these factors, Ben will never regain the ability to transform into Ultimate Forms.
