Ben 10

- Season 2

(2006)

The Tennysons encounter Phil, a former Plumber like Grandpa Max. Even though the Plumbers have retired, he still seems to find work that only a Plumber can handle. Is it just coincidence?

Ben discovers a new alien in the Omnitrix. As he tries to figure out the alien's abilities, a meteor crashes nearby. A giant tick emerges. It's already destroyed several other planets. Now Earth is next.

Apparently, Ben's aliens have been creating havoc across the country. Have they, really? As Federal agents come gunning for him in San Francisco, Ben gets the lowdown from a former friend.

In a what-if tale, Ben wakes up back at the start of summer vacation (with full memories of the coming weeks) and finds himself not the one to whom the Omnitrix affixes itself.

Kevin and Ben become part of an alien abduction where they find themselves enslaved and forced to take part in televised galactic gladiatorial games.

Ben is enthralled as a team of galactic superheroes trail two supervillains to Earth who are looking for the other chemical half of a solar-system-destroying explosive.

The Tennysons come upon a children's summer camp besieged by large, carnivorous fungus.

Texas oil drillers unearth the Mask of Apuk, key to the most powerful and destructive weapon ever created - the Sword of Echtua.

Charmcaster breaks her Uncle Hex out of prison to help him find the Keystone of Bazell and punish the one who got him imprisoned - Lucky Girl.

Being special guests at the first underwater resort excites Ben and Gwen till they meet the owner's snobbish grandson and a plethora of vicious undersea aliens.

One of Ben's aliens decides to leave the Omnitrix and take over the world but needs to merge with Ben to become whole.

Despite Gwen and Grandpa Max's warnings over toying with the Omnitrix, Ben messes around with it until - oops! - he breaks it and his aliens start coming out as fused hybrids.

Ben manages to unlock the master code on the Omnitrix, allowing him to change at will. It comes in handy now that Vilgax and Kevin 11 are teamed up and coming for him.
