About The Show
A year after Ben Tennyson defeated Vilgax, he’s known the world over as a hero — to kids, anyway. Adults are somewhat more suspicious. Armed with his mysterious new “Ultimatrix,” which can transform his aliens into their “ultimate” forms, Ben and his pals Gwen and Kevin are ready for more action. [via Gracenote]
