Grounded is the twentieth episode of Ben 10: Alien Force.


While fighting one of the Highbreed, Ben's parents catch him transforming into Swampfire. They forbid him from using the Omnitrix after having proof of a black eye from the fight, forcing Kevin and Gwen to fight the DNAliens by themselves. After trying to sneak out as Echo Echo, Ben gets grounded and is made to spill the beans about Gwen, getting her grounded, leaving Kevin alone. Kevin's trouble with the DNAliens and the Highbreed eventually pushes Ben over the edge, and he breaks out of his house as Humungousaur in front of his parents to help. 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, admitting that they are proud of Ben and understand what he needs to do.
