Ben Tennyson

Now 15, Ben is as adventurous as ever. But with Grandpa Max missing, he must also become a responsible leader. The Omnitrix has recalibrated, allowing Ben to access a new set of alien heroes.

Gwen Tennyson

Gwen has grown out of her tomboy phase and is now a confident teen. Her abilities have grown as well. Gwen can manipulate natural energy to create shields, tentacles and powerful blasts from her hands.

Kevin Levin

Kevin is a streetwise bad boy and the former nemesis of Ben. He can turn his body into any solid substance he touches. Secretly, Kevin has a crush on Gwen. But he'd never admit to it.

Grandpa Max

Max is a semi-retired member of an interplanetary police organization known as the Plumbers. Max mysteriously vanished while investigating a secret Highbreed plot.

Alien X

Alien X is Ben's most powerful alien, with the ability to turn his thoughts into reality, but he's also the most difficult to control, requiring negotiation with two other minds.

Echo Echo

He may be small, but Echo Echo is a living amplifier that can produce steel-shattering sonic waves and duplicate himself into an army of clones.
