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