In Alien Force, he wears a black t-shirt with a green jacket over it and a pair of jeans. His jacket in Alien Force has the number 10 on it.

Alternate Appearance
In Ben 10: Ultimate Alien MEGATRIX Search for Gwen and Kevin, Ben is transported to an alternate universe and his appearance changes. He looks more like a western green haired teenage boy.

Original Series
Ben was originally a typical ten year old boy, who grew up in Bellwood, and he was unpopular and bullied in his school.

However, his live changed the day he went in summer vacation with his grandfather Max and his cousin Gwen. A short time after they left Bellwood, Ben went on a walk and witnessed the crash of a strange capsule from space. This capsule happened to contain the Omnitrix, a powerful watch-like device, who fixed itself on Ben's wrist.

At first scared, Ben soon discovered that using the Omnitrix, he was now able to transform in ten super-powered alien creatures. Unable to remove it, he eventually learned to used it (though with relative problems) in order to become a super-hero. Though he occasionally arrest ordinary criminals, he was quickly led to also fight super-villains, starting with Dr. Animo, Kevin 11, and ultimately Vilgax, a vicious alien warlord who wanted to get the Omnitrix for himself.

Ben 10: Reloaded
In Ben 10: Reloaded,He is now 13 years old and still wears Omnitrix. he still the same and still keeping his secret hero from his family and people. He joins the Soccer team to be cool by his friend Sean to train him. In the end, Azumuth told him because the omnitrix will open. Ben release his omnitrix and it work. so, he decide to keep his secrets and put in his box and his life has better before.

Ben 10: Alien Force
In Ben 10: Alien Force, Ben now wears a black sports shirt, a green jacket with a white vertical line and the number 10, while his soccer uniform resembles his original clothing. He found a way to remove the Omnitrix roughly five years before the series began (possibly the way he did in The Final Battle: Part 1), allowing him to live a normal life. Ben now frequently patrons a local fast drinks place called Mr. Smoothy and indulges in strange flavors, (such as chocolate and carrot,) as well as a fast food place called Burger Shack, where he frequently orders "Chili Fries."

Contrary to the Omnitrix's previous ill-timed deactivation, the new re-calibrated Omnitrix appears to deactivate more or less to Ben's will or simply manually by rotating the dial as shown in the episode Alone Together. Additionally, it can be used multiple times in succession or indefinitely when used at its maximum, though its power will eventually deplete and will require time to recharge as shown in the episode Good Copy Bad Copy. Although he, like Gwen, is a descendant from the Anodyte race, Ben does not bear the "spark" to use their powers. Unusually enough, in the episode Voided, Ben seems to be able to see Animo absorbing energy. This may or may not be related to his Anodyte heritage. But, Ben has been able to wield the Omnitrix better than any other human could have. This may/may not be because of his Anodite heritage. Ben has also learned some degree of martial arts taught by his cousin Gwen.

Ben 10: Alien Universe
This series ran alongside Ben 10: Alien Force, although a good portion of the series was not so similar in terms of historic events. Most episodes, though, acted a lot like those of Alien Force's. Others were never written into the story. The series began airing about 8 months after Alien Force's premiere, in December of 2008.

Ben 10: R-Evolve
A Year Later, After the Highbreed war,Ben had a nightmare about the Demons arrived. Later,He walks with his girlfriend Julie are going to school. Suddenly, He saw Kai return to bellwood from the Academy. On they mission, his grandfather Max was Captured. They saw DNAlien try to attacked.But, DNAliens were fake. After the Journey, Ben,Gwen & Kevin are mission to save Max Tennyson.

Same as Season 3 of Alien force,

Ben 10: Ultimate Alien
In sequel , it takes place 3-4 weeks after the Alien Force finale, 16-year old Ben's identity is revealed to the world when a boy named Jimmy Jones pieces together the facts using the consistent use of the Omnitrix symbol. He's now a "megastar super hero" loved all over by kids but distrusted by many adults, mainly due to Will Harangue of Harangue Nation. The series featured Ben's new car, the DX Mark 10, which debuted in Ben 10: Alien Swarm, being gifted reluctantly to Ben as a late birthday present from Kevin after he threatened to destroy it with Humongousaur if he didn't get it instead of Kevin using it as a replacement to his broken car. He is still seen as dating Julie Yamamoto, now sharing a stronger bond with her, still helping the team from time to time. Ben will not be armed by the Omnitrix but by an evolved version of it, the Ultimate Omnitrix (or Ultimatrix) that has an evolved form of any and every form Ben has used prior to The Final Battle (series finale of Alien Force). Ben will also have no alteration of his ensemble in the series. He still appears as a very cocky teenager, a fact noted several times even by Albedo in Night of the Living Nightmare as he was disguised as Gwen and Kevin.
