Azmuth then gives Ben the true Ultimatrix a.k.a the Metatrix which he uses to defeat MetAggregor. But the power of Diagon within Ascalon (which is sealed within the Metatrix) overwhelms MetaBen causing him to turn evil until Professor Paradox is able to intervene by bringing the past(present) versions of Ben's team as well as Julie who were able to talk him out of the trance after which he summoned and battled Diagon and wins thereby vanquishing him. Afterwards, Azmuth returns the Omnitrix to Ben and states that he'll get the Metatrix back for one of his birthdays before he turns 41. Hopefully this will be Ben's true future, so if you can make that happen, please help me out. This movie might launch a series following the adventures of Rex Tennyson and his family/teammates.
