Benjamin "Ben" Kirby Tennyson was a normal ten-year-old kid, until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten different aliens. Though initially immature and clumsy, he grew as a true hero. By the time he was sixteen, he had become famous in not only his hometown of Bellwood, but on Earth and beyond. Ben has also become a member of the Plumbers
Appearance
Ben's physical appearance has changed throughout the series from a ten-year-old kid to a sixteen-year old teenager. However, he retains some recurring characteristics. He has shaggy brown hair, green eyes, pale skin, and he's quite skinny for his age, though he shows a lot of muscle definition due to being athletic.
When he was 5, as revealed in a flashback of how he first met his future frenemy Mr. Baumann, Ben wore green overalls with a white shirt underneath it. White numbers saying "5 1/2" where on a black square in front of his overalls.
In the original series and Omniverse flashbacks, Ben's usual clothes consists of a black-striped, white shirt with short sleeves, green pants and black and white shoes with black stripes. Ben wears the prototype Omnitrix on his left wrist.
In Alien Force and Ultimate Alien, Ben wears a black shirt, blue pants and a green jacket with white stripes and the number 10 on it, and black shoes. Ben wears the prototype Omnitrix in Alien Force and the Ultimatrix in Ultimate Alien on his left wrist.
In Omniverse, Ben wears a shirt which is black and has a green stripe in the middle with a white 10 and green stripes on the sides of his shirt. He wears brown pants with pockets at the knees and green and white shoes. He later gains a white hooded jacket with green stripes on both arms and a green number 10 on the right side. He wears the Omnitrixon his left wrist.
Personality
Ben is initially portrayed as a cocky, arrogant, and immature boy who tends to make jokes, even when fighting enemies. He easily gets full of himself and enjoys attention from others. This attitude can sometimes make him look obnoxious or dumb, often resulting in criticisms from Gwen later Kevin and a few others. It also causes several conflicts between him and Azmuth.
These traits, however, as hinted in The Forge of Creation, stem from Ben's attempts to hide his own fear about the situation (though he denied it and said he was actually oblivious). Even so, he's matured since the first series and although he can be goofy, he's also capable of great leadership skills and tends to get serious when the situation requires it.
Despite his immaturity, Ben is actually good-hearted, and his actions are motivated above all by a strong and sincere will to help others in need. He's shown to deeply care for other's lives, and would choose to save people by himself, even when he dislikes them (such as Cash and JT). This causes him to have a strong dislike for sacrifices or life compromises and occasionally acts against reason, such as when he chooses to save half-cured DNAlien Tyler over seizing the key for the Highbreed's invasion (Inside Man), or when he tries to save the Sentinel while losing the last Map of Infinity piece to UltimateAggregor (Perplexahedron). When meeting an enemy in trouble (like Kevin or the Highbreed), he'll usually attempt to help them rather than win the hard way. While this somehow overly idealistic nature is often criticized by Azmuth, most characters usually consider it as Ben's most important quality. Paradox once even stated that he had the gift to make the right choices at the right moments.
When he sees people hurt by his fault or because of his failures, Ben tends to get mad and acts much more violent and aggressive than he usually does. For example, when Overlord kidnapped Julie, or when Aggregor successfully absorbed the Andromeda aliens, Ben went berserk and beat them up with all his strength, and, in Ultimate Aggregor's case, to the point where Gwen stopped him from attacking more. Also, when Kevin mutated again shortly after stopping Ultimate Aggregor and temporarily went back to his psychotic way, hurting all the Plumbers' helpers, Ben became willing to kill Ultimate Kevin by any means necessary. He began acting ruthless, aggressive, pessimistic, cold-hearted, nasty, and even ready to fight Gwen as Way Big when she attempted to stop him. Gwen, however, was eventually able to convince him to try another way as he was about to kill Ultimate Kevin. During the episode, Ben confesses to Max he feels guilty for letting fame get into his head, and claims that he is trying to act more mature for once. Finally, in The Purge, when the Forever Knights are holding a large group of aliens hostage (and have killed some aliens already), Ben threatens to hunt the Forever Knights down for the rest of their lives if they don't let the aliens go.
Powers and Abilities
Ben has been trained in hand-to-hand combat by black belt Gwen (as shown in Be-Knighted), Max, as well as various years fighting aliens, and received a basic Plumber training. Though he has only been trained on a weekly basis in order to minimize his reliance on the Omnitrixes/Ultimatrix, he is still proved to be quite exceptionally skilled in basic hand-to-hand combat as well armed and unarmed combat, being able to easily dodge shots from Manny's blasters and proceed to disarm him while in human form in Above and Beyond. Ben was able to hold his own against Pierce, and Max hinted that Ben was a highly skilled fighter, even as a human in Voided, expressing surprise about the fact he lost to Pierce (though it is then revealed that Ben had lost on purpose). Another hint of his exceptional hand-to-hand skill is when he succeeded in the Plumbers' Academywith a 95 out of a 100 (without using the Ultimatrix). He is also shown to be a crafty fighter. However, according to Matt Wayne, Ben isn't a trained fighter and that he uses freestyle fighting.
It's evident that Ben is extremely smart in some respects, possessing an above average intelligence. It was even stated by Gwen that he really isn't working up to his potential at school, and he replies, "That's what they tell me." He also has fairly moderate grades (although not at Gwen or Julie's level). Chemistry is his toughest subject, yet he still maintains a B+ average.
In Where the Magic Happens, it is shown that Ben has a good memory, as he was perfectly capable of remembering and writing down the mystic rune-like symbols for entering the inter-dimensional realm ofLedgerdomain with just one glance from a distance. He was able to write the runes down.
In Perplexahedron, Ben is also shown to possess advanced intuition, as he was able to understand howPerplexahedron really worked with a small problem at first, but was then able to learn from the mistake and figure it out easily.
Ben is also a cross dominant, skillfully wielding tools and weapons in either hand, in human or alien form.
Ben was able to dodge Attea's punches with relative ease in Vilgax Must Croak.
