Benjamin "Ben" Tennyson (alias "Ben 10") : is the main character of the series. He is a 10-year-old boy child from Bellwood who found the Omnitrix during his summer vacation with his Grandfather Max Tennyson and his cousin Gwen Tennyson. The Omnitrix attached to his wrist and gives him the powers and abilities to become different aliens. He uses these powers to defeat evil while trying to escape the alien warlord Vilgax, who chases after him unstoppably in order to retrieve the Omnitrix.

For most of the series, Ben is shown as an immature, self-centered boy. In the beginning of the show, he only helped people for the benefit of feeling like a hero. This leads Gwen, Max, and others to doubt Ben and they wonder if he has what it takes to be a hero and if he should be the one holding the power of the Omnitrix. Through the series, Ben matures extremely and becomes a very capable leader in the sequel Ben 10: Alien Force when he's 15 years old due to Grandpa Max's disappearance and the threat of the Highbreed invasion. However, he tends to relax into old habits during the third season. He has an allergy to peanuts and has an Ornithophobia of peacocks (Ostriches in the Arabic dub). He also has Coulrophobia (fear of clowns). Despite his immaturity, Ben's actions are motivated above all by a strong and sincere will to help other people; he'll stop at nothing to protect his family and anyone else in danger. Sometimes, his nature tends to make him act childlike. Though often thought of by many other characters as being quite stupid, Ben actually proves to be smart and clever when needed, usually showing good skills when the Omnitrix doesn't provide him with the form he wanted.

In the episode "Where the Magic Happens", Kevin is surprised when Ben can memorize a sentence of magic symbols when only seeing it quickly. Gwen also states that he isn't working to his (possible greatness or power) in school, to which he agrees. While attending the Plumber College/school, Ben appears not to pay attention to his classes or the drill sergeant, yet still obtains a grade of 95 (out of 100) upon completion of the course. During the College/school, he was unable to handle the training as a human so he uses the Ultimatrix to get him through the training, despite his drill sergeant telling him not to use it. How much of this was from the previous training Ben received from his grandfather and his actions in the episode are unknown.
