In spite of all this, Ben is good-hearted and will stop at nothing to protect his family or anyone in danger.

In the episode " Perfect Day", he is shown with his pants down, revealing his blue-and-red sumo-slammer boxers.

He wears a white shirt with a black vertical stripe down the middle and brown pants. Ben is not above using the Omnitrix to pull pranks, even during urgent situations. He also tends to be a sore loser, especially when it is Gwen - with whom he shares a love-hate relationship - who outdoes him. He is something of a glory hog, sometimes taking credit that he does not deserve. No matter what bizarre form Ben takes, inside he is still the same mischievous 10-year-old boy.

This theme was further explored in the episode ' Kevin 11 '.īenjamin Kirby Tennyson is a typical ten-year-old boy- he plays video games, rides his bike, using the omnitrix, and often gets in mischief. He is first introduced in the episode " And Then There Were 10 ", where he finds the Omnitrix and, throughout the series, learns to use the powerful alien device responsibly. Benjamin "Ben" Tennyson is the main character of the series.
