Ben Tennyson

"It's Hero Time!"

- Ben's catchphrase.

Benjamin Kirby "Ben" Tennyson is a Human, cousin of Gwen Tennyson, and the grandson of veteran Plumber Max Tennyson and the Anodite Verdona. At the age of 10, he came in possession of the Omnitrix, a watch-like alien device containing genetic material from numerous different species, which allows the user to temporarily transform into a number of alien forms.
