Ben Tennyson (BotO)

## Appearance

Ben's physical appearance has changed throughout the series from a ten-year-old to a sixteen-year-old. However, he retains some recurring characteristics. He has unkept 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.

### Regular Appearances

In the *Omniverse* flashbacks in which he was 5 years old, Ben wore green overalls with a white shirt underneath it. White numbers saying "5 1/2" were on a black square in front of his overalls.

In *Omniverse* flashbacks, Ben's usual clothes consisted of a black-striped, white shirt with short sleeves, military green cargo pants with side pockets with a black belt hidden under his shirt, and black and white sneakers with black stripes. Ben wore the prototype Omnitrix on his left wrist.

In *Omniverse*, Ben wears a black shirt that has a green stripe in the middle with a white 10 and green stripes on the sides of his shirt. He wears brown cargo pants with pockets at the knees with a brown belt hidden under the shirt 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 for some time. He wears the Omnitrix on his left wrist.

In *Omniverse*, while riding the Tenn-Speed, he wears a white helmet with the number 10 on it, a green visor, a short-sleeved black T-shirt, long white pants and a belt with the number 10 on it.

## Personality

Initially cocky, childish, and selfish, Ben's immaturity and attention-seeking behavior often led him to joke around, regardless of the situation. His allies often criticized his attitude, unaware of the fact that he used humor to mask his fears. Despite some childish attitude, he was heroic, caring and generally good-natured, always willing to save others at any time.

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's kind-hearted, willing to sacrifice even his own life for others. 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. 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, when Ben fails to save someone, or if someone gets hurt because of his failures, he becomes angry and much more violent. Perhaps the most notable of these instances is when Kevin willingly mutated himself to succeed where Ben had failed and stop Aggregor, Ben was set on killing Kevin, even fighting Gwen when she refused to help him. He also threatened to hunt down and destroy the Forever Knights once making Driscoll promise to cease the hunting of aliens.

Though often stated to be silly or unintelligent because of his immaturity, Ben is cunning and resourceful when needed, quickly adapting when the Omnitrix doesn't provide him with the alien he wanted.

Later on, Ben starts thinking of himself as more of a superhero than a Plumber, often remarking that he's not a cop, but a superhero. Although he once again became cocky, he retained his selfless and heroic nature.

## Powers and Abilities

Ben is a crafty, intelligent fighter, having trained in hand-to-hand combat by black belt Gwen and Max. He 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 various years of fighting aliens.

Ben is quite agile and acrobatic, being able to easily dodge shots from Manny's blasters before disarming him while in human form.

Ben actually uses freestyle fighting, being able to hold his own against Pierce. Max has hinted that Ben was a highly-skilled fighter, even as a human.

It is evident that Ben is smart in some respects, possessing an above-average intelligence. Gwen even stated that he really is not working up to his potential at school. He also has fairly moderate grades, maintaining a B+ average in his toughest subjects Physics and Chemistry.

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 a cross dominant, skillfully wielding tools and weapons in either hand, in human or alien form.

Ben has a knack for turning his weaknesses into strengths.

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 has remarkable pilot skills that function like a combination of playing video games and tap lessons Sandra made him take, but he would never admit it.

Ben is a decent musician, as he can play the guitar.

### Equipment

Ben is the wielder of the Omnitrix, which gave 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 gains additional forms by either unlocking them or by scanning the DNA of aliens he meets.

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 Jury Rigg.

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 transforming into aliens, the Ultimatrix included what is referred as an "evolutionary function", that allowed Ben to evolve his alien forms in order to get upgraded versions of them, referred to as Ultimate Forms.

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 prototype 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 prototype Omnitrix to bring back to life any species stored on Primus.

The Omnitrix also has a failsafe to help prevent Ben from dying. If Ben is in mortal danger and the Omnitrix is in recharge mode, it will automatically go into active mode.

## Weaknesses

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.

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. While later series will have this weakness downplayed due to differences in Omnitrix features and models, Ben still takes some time to fully master a alien form's potential.

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.

Despite his experience in using the Omnitrices and Ultimatrix, Ben still does not know every function of them. Due to his inquisitive nature and impatience, he has accidentally unlocked new functions such as the Master Control and the randomizer, which can at times do more harm than good.

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.

The 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.

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

Ben appears to have a short attention span at times, and more often than not it can get him into trouble.

Ben has an allergy to peanuts.

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

Ben's worst fear is that of peacocks.

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's left eye twitches whenever he tells a lie, but only Kevin appears to notice this.

Despite his piloting skills, Kevin is considered to be a better pilot than Ben.

Ben's worst subject is Physics, followed by Chemistry.

Ben is vulnerable to being erased from existence by a Chronosapien Time Bomb.

Ben can be banished back to his original timelines by a Chronosapien, as demonstrated with some of his alternate counterparts.

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