The Ultimatrix gives Ben access to new aliens and ultimate versions of some of his most powerful heroes. The Ultimatrix also lets Ben evolve his transformations into even more powerful versions. These ultimate aliens are 10 times more powerful; with 46 of them, there isn't much Ben can't do.
Ben's secret identity has been revealed to the world and he's now an international mega-star super hero, adored by kids all over the world, but distrusted by adults who see him as a walking danger zone. Thankfully, Ben's cousin Gwen and his friend Kevin, an Osmosian alien, are there to help him out when he gets in over his head.
Every new series needs a new bad guy and Aggregor may be Ben's most formidable enemy yet. Another Osmosian, he plans to absorb the powers of five aliens whose combined powers could make him unstoppable.
