Some of Ben's old enemies attack a school bus. Ben easily defeats them, and the grateful cheerleaders thank him. It's the start of a perfect day for Ben. Or is it? Duplicates of Grandpa and Gwen show up and tell him he's been captured, he's in a dream world, and the culprits are keeping him there so they can get the Omnitrix. Can Ben distinguish between what is and isn't real? Written by Jesse Sanchez

While creating havoc at the beach for fun, Ben discovers Ditto, a new alien within his Omnitrix entourage. Ditto can replicate himself many times over but with two drawbacks. First, injury to one will be felt by all. Second, Ben can't become Ben again unless all the Dittos are together. This sort of comes in handy when Dr. Animo, freshly escaped from prison, arrives with a giant seagull mutation to capture Ben and add his alien gene pools to Animo's transmutation matrix.

As Hex seeks the famous Fountain of Youth to restore his youth and thereby his magic, the Tennysons happen upon its presence by accident. Grandpa Max falls into a vat of it at a fair, splashing Ben. While their physical ages revert, so do their mental and behavioral ages, with Grandpa Max wanting to goof around all day while Ben becomes a whiny brat in need of a nap (with all his Omnitrix aliens becoming crabby little kids as well). Will it be enough to stop Hex from gaining the fountain? Written by statmanjeff

The Tennyson's attend the wedding of Uncle Max's other and grown nephew, Joel, with Ben as his reluctant ring bearer. The event has far greater significance than it seems. The marriage of Joel and Camille - a marriage of political significance by happenstance - will unify, or at least encourage a temporary truce between, two warring intergalactic factions; however, someone does not want that peace and works secretly to sabotage the proceedings. Ben's on it (if he's not shot as an alien party crasher first). Written by statmanjeff

The Tennysons encounter a trio of merciless road pirates while traveling through the southwest. Their initial disinterest in Max' Rust Bucket turns when its performance in thwarting their aggression against an eye-catching RV exceeds expectation. Soon the pirates make it theirs, planning not just to burn up the highway with it but blow it up entirely. The Tennysons, along with a helpful waitress, engage in a high-speed chase to get it back.

Rather than admit to Gwen he broke her new computer, Ben sneaks out to compete in an all-night pro-wrestling event (as Four Arms) for its $10,000 prize money. He faces off against two mutant brothers, Gaterboy and Porcupine, who need that prize money to pay off a loan shark who's keeping their mother as a marker. For Ben, these issues challenge his usual selfishness and lack of responsibility: replace Gwen's computer to cover his misdeed or help the brothers save their mother and family farm.

In the future, Ben 10,000's son Ken turns ten (a lad just as willful and self-centered as his father at that age). As a present, he gets his own Omnitrix but chafes at only getting ten alien heroes from which to choose. He accepts it nonetheless. While joyriding on his hoverboard, he meets and befriends another youth his age, unaware he's Devlin, son of Ben's archenemy Kevin. Devlin's plan: worm his way into Ken's trust and free his dad from the Null Void. Ken, unfortunately, is just the right kind of arrogant dupe to fall perfectly into this plan. Written by statmanjeff

The Tennysons have picked up Cooper, the grandson of a fellow plumber, when they hear of the Circus Freaks breaking into Fort Knox. Curiously, while the Circus Freaks don't take any gold, they're also not alone in the caper. No, not by far. When the Tennysons finally discern what the real objective is, they find a consortium of their greatest foes - the Negative 10 - waiting for them. Written by Jesse Sanchez / revised by statmanjeff

With Cooper's help, the Tennysons protect the Plumber base beneath Mt. Rushmore as members of Negative 10 lay siege. Voice analysis confirms Grandpa Max's suspicion that the Forever King is Driscoll, a former Plumber who years ago was kicked out in disgrace. Written by statmanjeff

The summer ends, and Ben and Gwen must each be returned home for the new school year. It's especially aggravating for Ben. National appearances of the Omnitrix aliens over the summer leaves the entire school abuzz, but Grandpa Max's instruction to keep their connection to the alien heroes secret denies Ben any bragging rights. Fortunately, when Vilgax decides to attack the school and threaten the town, he cements young Tennyson's reputation as a kid to look up to. Written by statmanjeff
