Ben Tennyson

**Benjamin Kirby "Ben" Tennyson** is the titular protagonist of the **Ben 10** franchise. He was an ordinary 10-year-old boy until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten 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, And He Is A One Of The deuteragonist (Along With Kelly, Tex the Robot, Lincoln, Bob From Ready Steady Build, George Beard & Harold Hutchins) & He Is Also A Legacy Character In Postman Pat The Movie 2 (2022) To How To Surviving The Evil Bob the Builder Killers.

## Appearance

Ben's physical appearance has changed throughout the series from a 10-year-old to a 16-year-old. However, he retains some recurring characteristics. He has unkempt brown hair, green eyes, pale skin, and he is quite skinny for his age, though he shows a lot of muscle definition due to being athletic.

### Regular Appearances

## Personality

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.

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, 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, when Ben fails to save someone, or if people get hurt because of it, he becomes angry and much more violent. 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 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.

In **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 various years of fighting aliens.

Ben can jump high in the air.

Ben has good reflexes, being able to easily dodge shots from Manny's blasters before disarming him while in human form, dodge 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 decent at playing some musical instruments, as he can shred on guitar and was able to keep up with a rock band on drums.

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. Despite this, Kevin is considered to be a better pilot than Ben.

Ben is very good at driving.

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 transforming into aliens, the Ultimatrix included what is referred as an "evolutionary function", that allowed Ben to evolve his alien forms, 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 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.

Ben has a Plumber suit, allowing him to survive in unsuitable environments. His suit was modified by Kevin to enable him to deliver electric shocks.

Ben temporarily wielded Ascalon, which also covered him in armor.

When in Sumo Slammers Smackdown, he had access to a sword.

## 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.

Ben is vulnerable to hypnosis.

Ben has an allergy to peanuts.

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

Ben is vulnerable to the cold virus.

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 worst subject is Physics, followed by Chemistry.

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

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. However, this was not an issue when he wielded the recalibrated original Omnitrix, as the device granted him full understanding of the aliens' powers.

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 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.

## Trivia

* Gwen's birthday is in December, which would put Ben's in December too, as they both share the same birthday. Their rivalry in the **Original Series** was caused by this.
	+ At some point, the crew considered Ben's birthday to be a reference to the premiere date of *And Then There Were 10*. However, they never nailed down a specific birthday to spare Ben some embarrassment, because after his birthday comes and goes, he will still be 16.
* Ben hates mushrooms, though this may have been a consequence of his ordeal with the Living Mushrooms.
* When Ben was 10, he used to sleep with his teddy bear, called Furry Freddy. However, Ben defended himself saying that Furry Freddy had his own bed, which happened to be right next to his.
* Ben passed the third grade by choosing C for all the answers on multiple-choice tests.
* Ben's left eye twitches whenever he tells a lie, but only Kevin appears to notice this.
* Ben does not have good table manners.
* According to both Azmuth and Sir George, Ben is the same as they were when they were young.
* Ben's history now has to be read at the Plumbers' Academy. It comprises approximately a "chapter and a half."
* Ben's favorite color is green, and his favorite food is chili fries.
* Ben's first crush was Patty Berkenfeld from 3rd grade.
* Ben has a scar on his body in the shape of New Jersey.
* Ben's favorite drink as a teenager is smoothies from Mr. Smoothy, despite hating them when he was 11 years old.
	+ He is still searching for his favorite smoothie flavor. Up until *So Long, and Thanks for All the Smoothies*, he never tried the same flavor twice.
* Ben has a habit of referring to other members of his aliens' species by the names he gives his aliens because he does not know the names of most of his aliens' species.
	+ As such, he is often surprised on hearing them, such as when he learned from Hokestar that Bloxx is a Segmentasapien, but never admits to this.
* Ben has received an honorary doctorate degree from Friedkin University.
* As of **Omniverse**, Ben's shoe size is 10.
* Ben will have a glorious future. Azmuth even said that Professor Paradox once told him of Ben's "grand destiny" and that Ben would be "the legendary being who..." before Paradox cut him short.
* Ben was the first freshman to start as goalie on his school's soccer team.
	+ Ben still plays soccer when he can.
	+ The reason Ben plays soccer as a goalie is because Dwayne McDuffie used to play competitive soccer as an All-State Goalie in school.
* In **Alien Force**, Ben was in his freshman year of high school.
	+ In **Ultimate Alien**, his teachers were not nice on grading him, but they were fine with his bad attendance record.
	+ Ben still goes to school in **Omniverse**, but not much. He can get an excused absence very easily, and his assistance to the Plumbers counts as work-study.
* Ben used to shout the names of his aliens because they were asserting their identity as they gained consciousness, as well as to strike fear into his opponents. He stopped doing so, and changed his outfit, in **Omniverse** because he got tired of it.
	+ It was Dwayne's idea to have Ben shout the names of his aliens, as he thought it would help younger fans know the aliens' names.
* Ben has a lot of pull with the Plumbers.
* It is unknown if Ben gets paid for his Plumber work.
* Ben has other friends than the ones seen on-screen, but his coming out of retirement in **Alien Force** pushed them away.
* Ben has not thought about his career plan at all.
* Ben misses the good old days when he used to hang out with Gwen and Kevin without being mobbed by fans, so much that he secretly hates being famous and wishes he had his secret identity back.
* Ben knows some things about the original Ultimatrix that Eunice doesn't, and vice versa.
* Ben considers both Rook and Kevin his best friend.
* Ben still owns several black T-shirts.
* Ben sometimes goes to Undertown just to hang out.
* Ben sometimes thinks about moving to an apartment or Plumber Headquarters due to the trouble he brings to his home.
* Ben owns a Tetramand flag in his bedroom.
* Before the events of the **Original Series**:
	+ Ben and Gwen once did not speak to each other for two months over an argument about a stick of gum.
	+ At one point, the arguing between Ben and Gwen had gotten so bad that their parents refused to take vacations together anymore.
* During the road trip in the **Original Series**:
	+ Disliking Max's cooking was one of the few things Ben and Gwen agreed on.
	+ Ben was secretly sorry for what happened to Kevin.
	+ Ben still had gym clothes from the first grade in his gym locker.
* Sumo Slammers is Ben's favorite game, book, and TV show, followed by Space Pirates.
	+ In the **Original Series**, Weird World was listed as one of Ben's favorite TV shows. This was changed in **Omniverse**, as Ben stated he did not watch Weird World very often as it was on at the same time as Sumo Slammers.
* Ben's fight with his hero (Kangaroo Commando) in *Super Alien Hero Buddy Adventures* is one of his favorite memories.
* When he was younger, Ben's high energy often got him into trouble. As he got older, he learned to focus that energy into sports.
* The loss of Feedback, who was Ben's favorite alien at the time, was supposed to be the reason Ben took off the original Omnitrix and retired from being a hero, but it was ultimately Cartoon Network executives who vetoed the idea, which many crew members were thankful for.
	+ Prior to **Omniverse**, the five-year gap between the **Original Series** and **Alien Force** was discussed and various possibilities were kicked around, everything from "Wow, what if there's something huge and cool that happened there" to "Maybe absolutely nothing interesting happened there".
	+ Although the **Alien Force** crew did not specify how long Ben had the Omnitrix off, the **Alien Force** master brief states that he removed it shortly after defeating Vilgax in ***Secret of the Omnitrix***.
* Many voice actors auditioned to voice Ben in **Alien Force**. Yuri Lowenthal was called back multiple times before landing the role.
* Ben's **Original Series** design was made by Dave Johnson, while his Ultra Ben persona was designed by Thomas Perkins.
* Initial concepts for 15 and 16-year-old Ben's **Alien Force** and **Ultimate Alien** design were made by Glen Murakami. His head and hair were reworked by Glenn Wong, who also gave him his green jacket, while colors were added by Chris Hooten.
	+ Ben's green trunks in *What Are Little Girls Made Of?* and *In Charm's Way* were designed by T.J. Collins.
	+ 10-year-old Ben in **Ultimate Alien** was designed by Glenn.
* In the Gweniverse, Ben is not an Anodite and does not know magic. In fact, he does not have any powers in general. He is essentially a tagalong that gets in Gwen's way.
* Ben (as seen in **Alien Force**) was one of the characters featured in the 2009 Official BBC Children In Need Medley.
* Duncan Rouleau claims that the four alternate Bens featured in *Alien X-Tinction* are the same as the Ben Prime from the previous four series. However, there are subtle differences between the Bens compared to their Classic counterparts, such as **Ultimate Alien** Ben wearing his Ultimatrix backwards. While this is likely an error, it is never stated whether or not Maximillian or **Alien Force** Ben's device can travel through time. Furthermore, Cartoon Network considers **Alien Force** Ben and **Ultimate Alien** Ben to be two distinct Bens from different dimensions. As such it is open to interpretation as to whether or not they are Ben Prime. **This wiki however, considers them separate characters who are based on the Bens from the series they represent.**
* Ben Tennyson Is A Newest Member Of The Mannysweep Team In Postman Pat The Movie 2 (2022).

## Characterization and design

* Cartoon Network Studios felt that Ben 10's depiction was too "familiar," reviewing, "Although Ben Tennyson looks different from Dexter From Dexter's Laboratory, Johnny Bravo, Samurai Jack And Mac From Foster's Home For Imaginary Friends, Ben Tennyson is very much the same type of individual: a Boy With His Omnitrix To Transform Into 10 Aliens.
