Ben returns home after the summer vacation ends and is told by Max that he must keep the Omnitrix a secret. This is made more difficult with his classmates admiring the alien heroes that they've seen on the news; unaware that it is Ben himself. Initially disappointed, Ben gets the chance to use the Omnitrix when Vilgax attacks, yet again looking to take the device from Ben. All four Tennysons (Ben's father helps) fight off Vilgax's drones running amok in the city. When Vilgax appears again, easily fending off Ben, Ben's father suggests leading him into the underground gas line, which they ignite to incinerate the villain. Ben's secret is revealed to the public during the affair, and Gwen ends up transferring to his school. Just when it seems like everything is quiet, Dr. Animo shows up with a cadre of mutated animals, which Ben and Gwen get ready to fight.
