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.

Appearance
Ben's physical appearance has changed throughout the series from a 10 year old to a 16 year old. However, he retains some recurring characteristics. He has brown hair, green eyes, pale skin, and is quite skinny for his age, though he shows a lot of muscle definition due to being athletic.

History
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 him to temporarily transform into a number of alien forms.
