Benjamin Kirby "Ben" Tennyson was a normal ten-year-old kid until he found the Omnitrix, a powerful watch-like device that allows him to turn into ten different aliens. Though immature and clumsy, he uses the Omnitrix to stop evil, but that doesn't stop him from using it for his own personal needs.

Ben is childish and cocky, and likes to have fun. He doesn't like to do cleaning.[1] His reckless behavior often lands him in trouble. Besides his childish behavior, Ben is heroic and caring, willing to help and save anyone in need.

Ben is not into nerd culture as much as Gwen, and usually teases her and geek culture. Despite his bratty and indifferent demeanor, Ben is, by far, anything but ignorant.

Ben is afraid of squids, more specifically, tentacles. He has grown the courage to use them as Gax, but the fear is still there when he's a human.

After Kevin Levin started bullying him, he apparently developed a fear of public restrooms. He was also unable to eat lunch at the school cafeteria for around 3 months.[2] This led to him developing a grudge against Kevin, which has amplified upon finding out that he has his own Omnitrix.

Ben can get bored very easily, and is not good at math and science.

In Omni-Tricked: Part 1, Ben didn't listen to Gwen when she told him Gax wasn't a good choice for Ben to turn into while the volcano was erupting, instead of listening to her, he used Gax and did it his own way.



Gwen Tennyson

Ben and Gwen have a pretty good relationship. They argue here and there but they always end up forgiving eachother. At times, Ben finds her advise helpful, but often ignores it.

Max Tennyson

Ben and Max almost have a father and son relationship. Max often gives Ben advice, but Ben is annoyed by it. In Chicken Nuggets of Wisdom, Ben starts to accept the fact that his advice is helpful and he should listen to him more.


Some time prior to the series:

Ben joins a play in the first grade, but ruins it due to his fear of tentacles, he then gets laughed at by Cash and J.T.

During fourth grade, Ben constantly gets bullied by his soon to become rival, Kevin Levin.

During the start of the summer, the Omnitrix fell down on Earth, jumping on Ben's wrist. Some time after this, he meets Hex, Dr. Animo, and LaGrange, and becomes enemies with them.

In Waterfilter, Ben awakes a Hydromander by using Cannonbolt and jumping into Niagara Falls. He uses Overflow for the first time. He later defeats the Hydromander as Overflow.

In The Ring Leader, Ben enters a wrestling match, and fights Iron Kyle for the first time. Ben ends up destroying his suit as Overflow, but they both end up getting disqualified.

In The Filth, Ben is forces to stay in the Rustbucket and do chores, he ends up loosing it to Maurice and Sydney. He tries everything to get it back. Soon Ben arrives at a toxic waste dump, where Maurice reveals that they are creating a maggot monster out of garbage. Ben uses Four Arms to defeat the maggot monster, while sacrificing a clean Rustbucket in the proccess.

In Rustbucket RIP, Team Tennyson travels to a historic town, where he and the rest of Team Tennyson meets Billy Billions.

In Omni-Tricked: Part 1, Ben faces off with Dr. Animo as Cannonbolt. He ends up failing, but he unlocks a new alien, Gax. Later on, Ben, alongside Gwen and Max, visits an underground construction site, where they seek help from Max's old buddy Phil. Ben saves Phil from a cave in as Stinkfly. Ben and Phil tries to get the train started. The bounty hunters soon show up and tries to take Ben. Ben fights them for a while until a cliff approaches and the bounty hunters leave. Ben saves Phil as Wildvine before the train falls off. The four relocates to a forest where no one can get hurt. Phil puts a device on the watch so he could get more readings. Ben leaves and decides to test out Gax. After playing around and damaging the watch, Vilgax shows up in his ship. Vilgax takes Gax's DNA and becomes whole again. Ben tries to fight off Vilgax but ends up getting beat in the end. Soon the team drives to the volcano Ben sealed up earlier to stop Vilgax from absorbing lava. Ben fights Vilgax once more but ends up failing to defeat him again. Vilgax repairs the Omnitrix and Ben uses Upgrade to take down the ship. Vilgax has Ben caught, but Ben upgrades the Omnitrix using Upgrade, and thus creating Glitch. Ben takes down Vilgax utilizing all of his aliens, switching from alien to alien at will, with out even touching the watch. Later that day Phil breaks the news the Omnitrix is functioning the same way it did before Gax arrived.

In Out to Launch, Ben and the rest of team Tennyson visits a space launch. There the space ship takes off unexpectedly. Ben uses binoculars to find out what's the problem, and notices it's Vilgax, who survived their last encounter. Ben transforms into XLR8 and chases after the spaceship. Ben times out on the ships wing. The watch times in automatically and Ben transforms into Grey Matter to sneak in. Ben meets Captain Betts McCabe. Ben and McCabe works together to get to the cockpit. Gwen soon opens the door leading there and Vilgax sees Ben. Ben transforms into Omni-Enhanced Diamondhead and takes on Vilgax. Ben ends up blasting Vilgax out of the ship. The ship is soon landed by Captain McCabe, with the help of Ben.


The Omnitrix: A powerful device that allows Ben to transform into 10 different aliens with a variety of different skills and powers.


Whenever the Omnitrix times out, Ben is left powerless unless he switches into a new alien form. In addition to gaining the selected alien's powers, he gains its weaknesses. The Omnitrix also mistransforms at times, sometimes choosing an alien not fit for the situation.

He is allergic to animals.[3]

Ben is scared of anything with tentacles, including squids, snakes, and even Ectonurites.


Ben 10

Video Games

Ben appears in every Ben 10 video game.


Benjamin is a name from the Hebrew name בִּנְיָמִין (Binyamin) which means "son of the south" or "son of the right hand" going back into the Tanakh (called the Hebrew Bible by Christian scholars), a name of one of the sons of Jacob. His name, "Ben," is to create a rhyming effect between his first name and the number Ten. Also, his surname is a reference to 'Ten' of Ben 10.


  • Ben is 7 seconds younger than Gwen.[4]
  • Ben does not believe camels and reindeer actually exist.[5]
  • The biggest adjustment Tara Strong had to make in voicing this version of Ben is that Ben is not as mean to Gwen as his Classic Continuity counterpart.[TS 1]
  • The first alien Ben has ever turned into was Four Arms.[DR 1][6]
  • Ben's winter outfit is the same as Ben's occasional appearance in Omniverse, but it lacks the green 10 logo, the cuffs are white and has an extra pocket on the torso.
  • Ben's flashback outfit is a direct reference to his original series outfit.
