Ben 10 lives with her cousin, grandpa and their caravan bus

Gwen Tennyson - Gwen isn't an alien, she's worse, she's Ben's cousin! She is cool as she is smarter.

Grandpa Max - Ben's ex-army grandpa isn't an alien, but he knows something about 'em. He's also really cool and helps Ben out with his alien extermination projects.

Ghostfreak Ben 10 Hero/Charater Figure

Ghostfreak - Turning into this shadowy alien lets Ben walk through walls and turn invisible, as long as it's kinda dark. It's super-powerful and super-spooky.

Wildmutt Ben 10 Hero/Character Figure Toy

Wildmutt - This dog-like alien form is part wolverine, part quill-shooting porcupine, and all blind. Ben can't talk in this form either, but its super-senses means it doesn't need to see to pee on your leg!
