EPS03
The Tennysons camp by a lake that - wouldn't you know it? - has a monster in it (a true behemoth), but only Ben has seen it. Having recently dressed up as a sea monster to scare Gwen, he's now taken for a boy who's taking a joke too far. Only the creepy Captain Shaw believes there's a monster in the water, but he's not the sterling character needed to help Ben regain his good word; however, when the monster later makes a very public appearance, Ben's word is restored and he's off to join the captain for a monster hunt, much against Grandpa Max's instructions.

EPS06
Feeling gypped at a boring mid-west tourist attraction, Ben's payback ruins several exhibitions. One exhibit, though, turns out to be a lot more than anyone bargained for when it releases a relentless electrical prankster named Megawatt.
EPS07
Ben's misuse of the Omnitrix for personal gain gets the Tennyson's booted from a 4-star hotel. Chafing against Grandpa Max's subsequent punishment, Ben heads out on his own, with Gwen trailing after him. At an arcade, they come across Kevin, a savvy street urchin living on his own and answerable to no one, who shares in Ben's current disrespect for authority and self-centered sense of independence. The two hit it off. When Kevin runs afoul of some street toughs, Ben uses the Omnitrix to help him out, and the two soon partner up. As it turns out, Kevin, unlike Ben, is a natural-born superpower, able to absorb energy like a sponge, but as his callous disregard for others becomes apparent, their friendship turns adversarial, and Ben has a supervillain to contend with, able to absorb and copycat his alien powers. Written by statmanjeff
EPS08
A clash with a ruthless gang of lady criminals in New Mexico puts Grandpa Max in a hospital but it also turns the gang leader into a cyborg when one of Vilgax's damaged trackers merges with her. The resulting trouble from trackers honing in on the Omnitrix puts Ben in mind to distance himself from Max and Gwen for their safety, but it also puts Ben in contact with Vilgax for the first time. Written by statmanjeff

Written by Jesse Sanchez
EPS10
A grateful museum gives Ben (as XLR8) some souvenirs after he foils an evil wizard's attempt to steal a recently discovered spell book. When Gwen gets jealous over the lavish public attention Ben receives, he gives her one of his souvenirs. She soon discerns it's a magic charm that makes everything go her way, enough for her to proclaim herself Lucky Girl. Now the Tennysons have two superheros in the family (and an evil wizard out to thwart them both). Written by Jesse Sanchez
EPS11
Ben's penchant for using the Omnitrix for personal gain lands him in trouble again (but in part due to the Omnitrix behaving unreliably). Transforming at a water park to enjoy a height-restricted slide, Ben, to his chagrin, ends up as the diminutive Gray Matter, and just as Howell, an alien fanatic, comes along. Excited by proof of aliens on Earth, Howell grabs Gray Matter and, anticipating fame, notoriety and respect, contacts The Organization, a secret society bent on laying hands to all the alien artifacts it can get, but its reactions aren't what Howell expects or what Ben can live with. Written by statmanjeff
EPS12
Ben picks up a summer cold, leaving him at the mercy of both a severely runny nose and Grandpa Max's malodorous Asian remedy. Meanwhile, a villain with power over bugs takes his wrath out on a city when its councilwoman attempts to demolish the dilapidated building he and his bug hordes live in. Ben's cold impedes his efforts to rescue the kidnapped councilwoman by adversely affecting his transformations. Worst of all is the bug maniac's final retaliation - setting the city's nuclear power plant to meltdown and explode. Written by statmanjeff
