Ben Tennyson was a 10-year old boy superhero until he was possessed by Zs'Skayr. He currently appears in Ben 10: Shadows.


In the series, his usual clothes consisted of a black-striped, white shirt with short sleeves, green pants and black and white shoes with black stripes. Ben wears the Omnitrix on his left wrist. He hair gets longer and get red cat-like eyes and nails long for a 13-year old boy.


Ben was portrayed as a cocky, arrogant and immature boy who tends to make jokes even when fighting. He easily gets full of himself and enjoys attention. He has now become a matured teen who hates heroes and gets a craving of world domination, thanks to Zs'Skayr.
