Ben 10 (Classic)

Kevin 11 is back and he wants revenge. Now with the ability to take the shape of several of Ben's alien personalities, Kevin's been committing crimes and framing Ben for them.

In this "how 'bout?" episode, Gwen gets the Omnitrix and the power that comes with it. Meanwhile a very confused Ben must come to grips with his "new role", as he teams with Max and "Gwen 10" to take down Vilgax who's come to earth in hopes of obtaining the watch.

Ben and Kevin 11 are beamed up to a space ship where they're shackled to one another. There, they must learn to fight together in order to bring down a vicious promoter who pits aliens against aliens in gladiator battles.

When an intergalactic trio of alien super heroes arrives in Pittsburgh to track down the bounty hunter Six Six and his alien henchman, Ben joins the trio. Although he wants to become a classic hero himself, Ben soon realizes these "heroes" are more messed up than his real family, and instead ends up teaming up with Max and Gwen to save the day.

After Max just misses running over a fleeing summer camper on the road, Ben, Max and Gwen take the boy back to his nearly deserted camp. It's nearly deserted because a race of alien mushrooms has taken over the camp as their first step for world domination. As Gwen and Ben argue as to whose birthday is more important, (since they both fall on the same day), Gwen's able to rally the remaining campers and Ben discovers yet another alien hero, Wildvine, as they team up to take down the mushrooms

When Max finds out that part of an alien weapon has been unearthed in Texas, he becomes obsessed with finding it.

Max's old friend has just built the world's only underwater resort, and Ben, Gwen and Max are invited for a sneak peak.

Now the aliens want their energy orb back and destroy the resort in order to get it.

Ben's internal demons get externalized when Ghostfreak escapes from his watch and becomes a full fledged being on his own. The renegade alien then realizes he needs to meld with Ben's DNA in order to survive, while Ben must figure out a way to get Ghostfreak back in the watch.

Dr.Animo has broken out of jail, and has been tracking down Ben, intent on revenge. At the same time, Ben's broken off a piece of the Omnitrix, and as a result, has turned into weird alien combinations, i.e. StinkArms. When Animo gets a hold of this piece of the watch, he uses it to create a ray that will mutate the entire world, until our heroes stop him.

Ben's feeling cocky with the watch. He's "unlocked" its secret, and now can become any alien he wants, whenever he wants. That's the good news. The bad news is, after finding one another in the depths of space, Kevin 11 and Vilgax have teamed up and have returned to earth to destroy Ben and get the Omnitrix.
