(This is an aged up version of Ben Tennyson that I've taken some minor creative liberty with, but is mostly entirely cannon)

Benjamin Kirby "Ben" Tennyson was an ordinary 10-year-old boy until he found the Omnitrix, a powerful watch-like device that allowed him to turn into 10 different aliens. Though initially immature and clumsy, Ben grew to be a true hero. By the time he was 16, he had become famous in not only his hometown of Bellwood but on Earth and beyond. Ben has also been deputized by the Plumbers and has gained more aliens as time progressed. Now at 25 Ben has gained full control over the Omnitrix and has even had the Master Control unlocked for him.

Initially cocky, childish, and selfish, Ben's immaturity and attention-seeking behavior often led him to joke around, regardless of the situation, which landed him in trouble with adults. When he was 10 years old, he often used the Omnitrix improperly in order to benefit himself instead of actually helping others, such as using Grey Matter to search cereal boxes for a gold Sumo Slammer card. His allies often criticized his attitude, unaware of the fact that he used humor to mask his fears. It was also implied that, on some level, Ben helped people to get rewards and for the thrill of being a hero, rather than because it was the right thing to do. Despite some childish attitude, Ben was heroic, caring and generally good-natured, always willing to save others at any time even at the risk of himself. In spite of this good nature, heroism, and his moments of maturity, Ben could occasionally get carried away when it came to fame and recognition. This led him to act rather arrogantly and recklessly, and occasionally made dire mistakes and alienated his loved ones. However, he was quick to realize his mistakes and is quick to take responsibility and knew not to take things too far.

Over the years, Ben has displayed good leadership skills, as well as the ability to adapt his attitude to a situation, becoming serious when it's called for. He became more mature, responsible and sensible. He continues to be kind-hearted and willing to lay down his own life for others, such as when he attempted to sacrifice himself to set the sentient Ultimate Forms free from the Ultimatrix. His idealistic views and unwillingness to compromise his values – aspects condemned by Azmuth, yet commended by others – sometimes drive him to act against reason, such as helping his enemies if they need it (most remarkably Vilgax). Professor Paradox has praised Ben's good nature, going so far as to say he had the gift to make the right choices at the right moments, and even Azmuth himself states that Ben ultimately always does the right thing. Also, Ben doesn't give up and wouldn't let anyone stop him from doing what's right for those in need, especially his family, friends and mentors, or to bring enemies down, even when he once got a broken arm.

However, even as a teen, Ben still displays some of his negative childish traits at times, which usually comes to light when Ben gets too caught up with fame. Ben also has a violent, aggressive side: when Ben fails to save someone, is worried about the well-being his loved ones, or if people get hurt because of his failure, he becomes angry and lashes out, even at people he cares about. Perhaps the most notable of these instances is when Kevin willingly mutated himself to stop Aggregor, Ben was determined to kill Kevin, even fighting Gwen when she refused to help him. During the episode, Ben confessed to Max that he felt guilty for letting fame get into his head and claimed that he was trying to act more mature for once. He also threatened to hunt down and destroy the Forever Knights if Driscoll did not promise to cease hunting down aliens.

Though often perceived as unintelligent because of his immaturity and constant joking, Ben is cunning and resourceful when needed, quickly adapting when the Omnitrix doesn't provide him with the alien he wanted. He has once admitted that people assume he's not paying attention, but he actually is.

During the events of Omniverse, Ben started thinking of himself as more of a superhero than a Plumber, often remarking that he's not a cop, but a superhero.

Powers and Abilities

Ben is a crafty, intelligent fighter, having been trained in savate and karate by Gwen. He also knows Marquess of Queensbury boxing. He uses freestyle fighting, being able to hold his own against Pierce. Max has hinted that Ben is a highly skilled fighter, even as a human.

Ben has also received basic Plumber training, having succeeded in the Plumbers' Academy with a 95 out of a 100. On top of that, he has gained practical experience from years of fighting aliens.

Ben has good reflexes, being able to easily dodge shots from Manny's blasters before disarming him while in human form, dodge Sunder's axe attacks, Zed's lunges while the Omnitrix was in Recharge Mode, and a laser blast from Tummyhead.

Ben has an extraordinarily sharp memory, as he was perfectly capable of remembering and writing down the mystic rune-like symbols for entering the inter-dimensional realm of Legerdomain with just one glance from a distance. This is even more true for things that interest him.

Ben is surprisingly a natural at hoverboard-based combat, which generally requires intensive training and the use of holographic simulators. This is most likely because he can snowboard.

Ben is a decent musician, as he knew a variety of electric guitar techniques like shredding, hammer-ons, and pinch harmonics, and on drums, was able to keep up with a professional rock band.

Ben has shown himself to be quite proficient in using weaponry, such as a DNA Repair Gun and Ascalon.

Ben is proficient at driving, having been taught by Max. For example, he was able to swerve out of the way at the last second to avoid coming into contact with Eunice's crashing pod.

Ben has impressive piloting skills, as shown when, at 10 years old, he could adequately control a gyropod (a small ship designed for alien pilots) within seconds of testing, and at 16 years old, could pilot the Rust Bucket 3. He gets this skill from a combination of playing video games and tap lessons Sandra made him take, though he would never admit it. Despite this, Kevin is considered to be a better pilot than Ben.

It is evident that Ben is smart in some respects, possessing an above-average to high intelligence and maintaining a B+ average at school. Gwen even stated that he really is not working up to his potential at school

Ben has a knack for turning his weaknesses into strengths.

Equipment

Ben is the wielder of the Omnitrix (formerly the Ultimatrix and first Omnitrix), which gives him the power to modify his own genetic code in order to turn into various alien creatures. Traditionally, he could only transform into ten aliens at the beginning of both the Original Series and Alien Force, but he later gained additional forms by either unlocking them or by scanning the DNA of aliens he met.

When transforming into an alien, Ben gets all the creature's features, including its appearance, voice, all of its unique and special abilities and powers, strengths and weaknesses. Though he mostly retains his personality, there are some cases where the transformation causes a change in it, like with Rath and Juryrigg.

Though he usually uses his alien forms to fight, he can impersonate aliens as he did with Water Hazard to convince P'andor to go home, though he was only successful at getting P'andor to believe he was Bivalvan.


In addition to the primary transformations and evolutionary function, the Omnitrices and Ultimatrix can both be used for various purposes. Both have a built-in Universal Translator that allows Ben to communicate with most aliens that do not speak English.

The original Omnitrix displayed the ability to manipulate and repair genetic damage, a function he used to cure DNAliens and save the Highbreed from extinction. Azmuth also mentioned that Ben could use the original Omnitrix to bring back to life any species stored on Primus.

The current Omnitrix also has a failsafe to help prevent Ben from dying.

Weaknesses

Ben appears to have a short attention span and very little patience at times. More often than not, it can get him into trouble, such as not reading the directions when trapped in Sumo Slammers Smackdown. Though he has matured substantially since receiving the original Omnitrix, he is still a teenager with much to learn and is prone to irrational impulses and recklessness. (Now that he is older, he is much more level headed than he was in his teen years, though he does still struggle with these issues on occasion)

Ben has coulrophobia (i.e. a fear of clowns), which was indirectly caused by Max.

Ben is vulnerable to the cold virus.

Ben is vulnerable to hypnosis.

Ben is not immune to Corrodium and will be mutated when exposed to this mineral unless he either wears special protection or transforms into an alien.

Ben can be rendered unconscious by sedative quills, such as those generated by Argit's species.

Ben has an allergy to peanuts.

Ben can experience pain from electricity, such as that generated by a Nosedeenian and Phil as a Terroranchula.

Ben's worst fear is that of peacocks.

Ben's worst subject is Physics.

Whenever the Omnitrix times out, Ben is left powerless until he either dodges or switches to a new alien form. In addition to gaining the selected alien's powers and strengths, he gains its weaknesses. (This is no longer an issue as Ben has access to the Master Control and can change forms at will simply by thinking about which Alien he wants to become.)

Whenever Ben unlocks a new alien form, he is at a disadvantage of not knowing its abilities and weaknesses until he gains experience with using that alien. However, this was not an issue when he wielded the recalibrated original Omnitrix, as the device granted him full understanding of the aliens' powers.

Though the current Omnitrix is designed to work only for him, Ben still has not mastered it. According to Azmuth, Ben may get the Master Control on his 18th birthday. (In my version of an aged-up Ben Azmuth granted ben the Master Control when Ben turned 20 due Ben disapointing him....again and he has sense gained full control and mastery over it.)

The current Omnitrix does not actually mistransform, but rather it is due to Ben hitting the Omnitrix too hard, thereby causing the time-out function to select another alien at random.

At times, the natural biological behavior of certain aliens can override Ben's behavior, such as Big Chill's reproductive phase or Swampfire's blossoming process.

Any illness Ben is experiencing in his human form will affect his alien forms.
