First Appearance Ben 10: Race Against Time

Benjamin "Ben" Kirby Tennyson is the main character of the Ben 10: Race Against Time, Alien Heroes and Alien Swarm Universe.

He is very similar to Ben Prime and Ben Reboot, and is the owner of the Omnitrix and Omnitrifix.


He is a tall boy with dark brown hair. He is dressed in brown-greenish jeans and a white T-shirt with black stripes and a 10 on its chest. He wears black shoes.


He is very straight-forward and kind of an idiot. He is very hyperactive and loves to be a hero, mock his cousin Gwen, make bad puns, chili fries and smoothies.

He found his original Omnitrix when he was 10 years old, then he started fighting evil with his newfound alien powers. Most of the events of the original series happened to this Ben as well.
