While fighting one of the Highbreed, Ben’s parents catch him transforming into Swampfire. Seeing as he comes home with a black eye, they forbid him from using the Omnitrix ever again for fear of him getting hurt. With Gwen and Kevin on the trail of a Highbreed plot, Ben tries to sneak out of the house as Echo Echo. Once Ben’s parents see that he disobeyed their orders, they do what they think is best for their son’s protection and safety and ground him. His various attempts to aid his allies by phone and by computer only results in Ben being forced to tell his parents about Gwen helping him, resulting in her suffering the same fate as her cousin, and leaving Kevin alone to find out what the Highbreed are up to. Kevin manages to find out that the Highbreed are planning to use radioactive bat guano as a power source for a “surprise” (the hyperspace jumpgate in Los Soledad). Having been captured, Kevin’s trouble with the DNAliens results in Ben making a final attempt to persuade his parents to his cause, saying that if he does not help Kevin, it would be against everything they ever taught him, and so escapes as Humongousaur nonetheless. After a short battle aboard a small freighter carrying a rare isotope which the DNAliens plan on using, Ben’s parents come to the rescue, with one of Grandpa Max’s old Plumber guns, admitting that they are proud of Ben. They win the fight, and destroy the ship. They cancelled the punishment, apologized for the mistake, and say they understand what he needs to do.
