Kevin Levin (Classic)

Kevin Ethan Levin, AKA Kevin 11 AKA Kevin E. Levin, is a Human/Osmosian hybrid with the ability to absorb, hold, redirect, and discharge virtually any type of energy or matter through his body at will. He first appeared in the original series and quickly became one of Ben's most notable nemeses. However, he reformed in Ben 10: Alien Force, and then became one of the main hero characters. But in The Forge of Creation he is forced to absorb the Ultimatrix's power in order to stop Aggregor and becomes insane yet again. With the help of Cooper and Darkstar, Ben and Gwen manage to reverse his mutation(with Ult Echo Echo), thus bringing him back to sanity in Absolute Power Part 2.

Appearance
In the original series, Kevin had a thin, scrawny body with long black hair, pale skin, and dark brown eyes with black rings underneath them (a sign that an Osmosian had recently absorbed raw energy). He wore a torn black t-shirt, black studded arm bands, brown cargo shorts, grey knee-length boots, and a steel padlock necklace which was a spoil from his first crime: stealing a bike and using it to run away to New York. After he goes through his first mutation, the transformation completely destroyed his clothes, except for his cargo shorts.

In Alien Force, Kevin's mutation wore off and he returned to his human form. He has now grown into a tall and muscular young man. In this series, his eyes are now flat black without the dark rings around them (as he stopped absorbing energy after regaining his human form). His hair is the same length as it was in the original series but is no longer highlighted. During the first two seasons of both Alien Force, he wears a tight black t-shirt over a grey long sleeve shirt, blue jeans, and black combat boots. His hair, though still long, is slightly shorter than when he was younger and is styled into a choppy mullet. During season three, Kevin wears his blue, oil-stained mechanic's jacket over a white muscle shirt, grease-smeared jeans, and his black combat boots. After he goes through his second mutation at the start of season three, the transformation completely destroyed his clothes, except his briefs. As a result, Kevin had to wear an I.D. mask in public to appear human.

In Ultimate Alien, Kevin is shown wearing his outfit from the first two seasons of Alien Force.

Personality
When Kevin was eleven years old, he was a criminally insane sociopath, willing to hurt/kill anyone for his own personal gain and/or pleasure. This behavior and mentality stems not only from having been seen and treated as a freak by his peers and family, but also because of the side-effect Osmosians have with absorbing raw energy. His sociopathy and selfishness is made apparent when he was once willing to derail a train in the subway and kill countless passengers, only to cash in on the spoils afterward. As the series progressed, more of Kevin's personality was revealed. It would seem that Kevin had an extremely negative outlook on life because of the countless hardships and struggles he had to endure, feeling insecure about himself as well as having incredibly low self-esteem. He had a deep rooted hatred for other people and society in general; Ben once rebuked him about involving innocent people in his dangerous plans, to which he bluntly replied that "Nobody's innocent! They just haven't had the chance to make fun of me yet!" further emphasizing the negative impact society had on him. In a technical light, Kevin was just as much a victim as any other.

This all changed when he met Kwarrel, a fellow prisoner in the Null Void when Kevin was a prisoner there. Kwarrel was possibly the first and only person other than Gwen to have been genuinely sympathetic and caring towards Kevin, becoming somewhat of a father figure to him which greatly improved his personality.

In Alien Force, 5 years after the original series, a sixteen year old Kevin is seen. Despite being a con artist and an arms broker, he was noticeably more stable than his younger days; owing to his time with Kwarrel, somewhat mature but still had a bit of a jock attitude. As time went on and Kevin was accepted by Ben and Gwen, who were his most hated enemies in the past and now best friend and girlfriend respectively, his personality and psyche improved greatly to the point that he became a trustworthy and reliable ally and teammate. Although Kevin sometimes had relapses of delinquency, Ben and Gwen would look past this as they were now willing to trust him. In the third season of Alien Force, Kevin would once again be mutated by the Omnitrix; involuntarily absorbing feedback from it like the first time and became a living colossus composed of the various solid matter he had absorbed, including steel, Taedenite, concrete, and stone. During this time, Kevin was visibly disgusted with himself because of his mutation and fluctuated between bouts of uncontrollable aggression and severe depression that almost jeopardized his relationship with his friends, especially Gwen. After the final battle with Vilgax and the destruction of the original Omnitrix, Kevin was restored back to normal and resumed life as a normal looking human. His relationship with his friends further contributed to his mental stability as he once told Ben in "Perplexahedron" that he was grateful to them for changing his life. Verdona once stated that Kevin's current personality is similar to a younger Max Tennyson's. This, coupled with their rivaling knowledge of alien paraphernalia, makes this claim not that far-fetched.

However, things took a sudden turn for the worse when Kevin was mutated once again. Only this time he was driven completely insane, becoming a rageful and gluttonous monster that matched his grotesque form. Kevin became vengeful against everyone who had ever done him wrong, even if by the slightest fault. He was willing to hurt and kill anyone regardless of the consequences and could not be reached even by his friends, with whom he also vented his rage on. Kevin was unstable even more so than he ever was as a kid by being extremely violent, both physically and verbally. This is evident when he expressed his frustration against Ben the most for being a famous superhero and him being a monstrous freak. Having no control over his actions, Kevin became overwhelmed by an insatiable hunger for energy that unwillingly drove him to kill anyone who he came across to get their energies, regardless if they had powers or not. Even Gwen, who still believed in him, was willing to risk her own life to save him from going down further. At first, Kevin fought for what little self-control he retained by not hurting Gwen because of what they had before his turning, but his resolve soon waned when he "tasted" her energy and hungered for her as well. Through the combined efforts of Ben, Gwen, Cooper and Darkstar, they were able to revert Kevin back to normal.

Ben 10
Kevin Levin was born to Devin Levin and Mrs. Levin. Devin; an Osmosian and a Plumber, was the partner of Max Tennyson. After Devin died in the line of duty at the hands of Ragnarok, Kevin and his mother were left orphaned. Some time after Devin's death, Harvey Hackett came into their lives. Harvey fell in love with Mrs. Levin and married her, thus becoming Kevin's step-father; Kevin was only 4 years old at the time. Kevin wasn't fond of Harvey at the very least, especially since he saw him as a replacement of his deceased father as well as an obstacle for his mother's love. Harvey strove to be a good father figure to Kevin, whom he accepted and raised as his own, but it was undeniable that he was fearful of Kevin because of his dangerous powers, which only worsened their relationship. When he was just eleven years old, Kevin somehow became charged with energy and demolished their old home. This, coupled with the mental instability from absorbing the energy and his initial dislike of Harvey, instilled in him the delusion that Harvey convinced his mother to kick him out in the street (Harvey later revealed that he drove Kevin out of the house because he destroyed their home). Stealing a bike and wearing the padlock around his neck, he ran away and made his way to New York where he made his home under the city's abandoned subways.

Kevin is first encountered by Ben in an arcade, where, after befriending him, he was assaulted by bullies and saved by Ben as XLR8. The two attempt to steal video games from a warehouse and get caught by the police, forcing Ben to reveal his powers to him in order to escape. The two subsequently form a partnership to use their respective powers for personal gain; however, when Kevin rigs two trains (one carrying money and one carrying people) to collide, uncaring that the crash would most likely result in the deaths of several hundred people, Ben suffers a crisis of conscience and breaks off their partnership. Ben became Heatblast to stop

Kevin, but to even the odds, Kevin grabs onto Heatblast and absorbs his life force, DNA, and powers, changing him into an incomplete version of Heatblast (Fireblast). When Ben foils Kevin's plans and escapes, Kevin leaves to use his absorbed powers to get revenge on the bullies that tormented on. But Kevin's absorbed powers disappear and he reverts back to his regular form.

When Ben shows up as Four Arms to stop Kevin, Kevin absorbs Four Arms' life force, DNA, and powers and changes into an incomplete version of Four Arms (Six Arms). As Ben and Kevin fight, Ben gains the victory and offers Kevin a new home and a chance to be a good guy. Kevin accepts, but Ben realizes he lied and Kevin tries to take the Omnitrix off of Ben, but feedback from it changes Kevin back to normal and appears to be depleting his powers. He escapes and at the end of the episode reveals he still has Heatblast's powers.

Kevin serves as the main antagonist of the second season. His ability to project heat at the end of Kevin 11 is a result of the Omnitrix's feedback pulse: the amount of energy it emitted allowed him to fully absorb its powers, giving him access to every alien form Ben had at the time. However, because Kevin's ability to regulate this power is poorer than that of the Omnitrix itself, the energy suppresses his human form and forces him to remain as an alien most of the time.

As revealed in Framed, Kevin blamed Ben for this, so he used the powers of the Omnitrix to start a crime spree in San Francisco, both for his own benefit and to damage Ben's (or rather, his alien forms') reputation. Eventually, Kevin's ability to regulate the power fails altogether, causing him to permanently mutate into

what Vilgax would describe as a "misshapen, chaotic amalgam of creatures from the Omnitrix." This form has: Four Arms' head, body, left eyes, legs and feet, Grey Matter's right eye, Ripjaws lure, teeth, and gills on his torso, Upgrade's ''upper back, Stinkfly's wings, Diamondhead's right arm, Heatblast's left arm, Wildmutt's lower arms and gills/nose on his face, Ghostfreak's eye track running along his chest and lower back, and XLR8's tail. Because of this, Kevin fights Ben and as he was about to kill him, Lt. Steel from the Special Alien Capture Team (SACT) shoots him into the water and he is presumed dead, but at the end of the episode he is revealed to be alive.

After his mutation, Kevin gloats that he has all of Ben's original 10 alien powers plus his own, making him "Kevin 11" (the name Kevin is credited under in the ending sequence of the show). The known powers he could use include Stinkfly's flight (though he seems to forget he can fly) and slime spit, Diamondhead's crystal shards, shape-shifting arm, and invulnerability, Four Arms' strength, Wildmutt's agility, senses (as he has Wildmutt's gills/nose on his face), and quills, XLR8's speed and reflexes (though he forgets to use his speed to an advantage), Heatblast's fire blasts, Ripjaws' glowing lure, steel-bending jaws and ability to breath underwater (as he has Ripjaw's gills on his torso), and possibly Grey Matter's intelligence, Ghostfreak's invisibility and intangibility, and Upgrade's plasma beam (though he did not use their powers during the series). Kevin also retained his absorption powers while in this form (as seen in Back With a Vengeance, when he held and absorbed the blast from Gwen's plasma gun). Despite this, Ben observes that Kevin's powers weren't as strong as their pure forms (though, in terms of physical strength and durability, he was apparantly stronger than Ben as Four Arms), as seen when Diamondhead was able to easily catch and crush one of Kevin's crystals with his bare hands while the others shattered upon hitting him. This assessment is proven correct in Ultimate Alien as Aggregor stated that when Osmosians absorb the life force of other beings they can only gain the original creature's powers at 1/10 of their original strength without mechanical aid and can only use them temporarily unless they were to drain all of that life form's DNA and energy, including their life force, leaving behind nothing but a shrunken husk.

During his third appearance in Grudge Match, Kevin attacked Ben to get revenge, blaming his condition on him. As the two battled, they were abducted and forced to fight in Slix Vigma's gladiator games. During their battles, Ben helped Kevin to realize the advantages of his mutated form: because Kevin 11 was an amalgam of aliens, he could mix and match their powers to make up for their reduced potency. Although forced to work together, Kevin's only goal was killing Ben. After Ben and Kevin succeeded in escaping, Kevin attacked Ben and trapped him against the wall with Stinkfly's toxic saliva before moving in with Diamondhead's spear hand, gloating that no matter what alien Ben transformed into, he knew every one of them. Little did he know that Ben had discovered that there were more aliens in the Omnitrix and had unlocked Cannonbolt, whom he transformed into just as Kevin was about to skewer him before getting into an escape pod. Kevin nearly barged into the pod when he was stopped by Technorg, whom Ben had spared and he declared a life debt to. After Technorg helped Ben escape, he turned his attention to Kevin (who had called him a lap dog just as he was about to kill Ben). The two were transported to a different galaxy at the end of the episode while locked in combat. According to the advanced edition of the episode, Technorg beat up Kevin and left the ship to return to his home world while Kevin took the ship as his own.

Kevin returned in the episode Back With a Vengeance, where he teamed up with Vilgax to defeat Ben, and eventually managed to remove the Omnitrix with Vilgax's help. However, he betrayed Vilgax later in an attempt to leave both Ben and Vilgax in the Null Void and use the Omnitrix to take over the world, only for Ben to escape and leave him and Vilgax trapped instead. Kevin spent the rest of the series in the Null Void.

A dream version of Kevin appears in Perfect Day, as a hall monitor of a dream version of Ben's school. In the dream, Kevin was human but then changed into his mutated form (which, with it's Ripjaw's mouth and teeth more prnounced than usual, appeared uglier than it used to be, probably emphasizing of Ben's fear of Kevin) and fought Ben. When Ben took control of the dream, he was then able to defeat the dream version of Kevin in one fell swoop.



Kevin makes his final appearance in in the future non-canon episode Ken 10, who take place during the Ben 10,000 time line. During the Ben 10,000 time line, Kevin was trapped in the Null Void for 32 years. Kevin managed to break out of the Null Void several times. During one of his breakouts, he had his son Devlin with a girl on a Saturn colony.



During his time in the Null Void, Kevin absorbed the powers of the 11,000 aliens and monsters trapped with him. This allowed him to turn into a new monstrous hybrid form even powerful than the original one(strong enough to allow him to shrug off multiple direct blows from Way Big), transforming him into Kevin 11,000. This mutant form (like his Ultimate Alien mutation, Ultimate Kevin) does not have the same set-back as his first mutant form did (his powers being only 10% of their original strength) due to him having absorbed all of the DNA and energy of the aliens and monsters he absorbed, including their life force (similar to Aggregor), leaving behind nothing but a shrunken husk. Having completely mastered his powers, Kevin can now switch between his human and mutant form at will and even access some of his alien powers in human form to a limited extent, including XLR8's super speed and Four Arm's enhanced strength.

The episode begins with Ben's son Ken celebrating his tenth birthday, and to commemorate the occasion Ben gives him an Omnitrix of his very own. However, he equips it with a limiter, unwilling to trust his son with the power of the Omnitrix or to defeat villains on his own. Ken soon befriends a boy named Devlin, and the same night Kevin 11 attacks (actually Devlin, who has the ability to shift between his human form and his father's first mutant form at will). Unable to locate the Null Void, which Ben has moved after the events of Ben 10,000, he retreats.

Ken, also unaware of the move, endeavors to find it on his own, only to unwittingly lead Devlin, who is Kevin's son and can transform into his father's mutant form, right to it. Devlin releases his father from the Null Void, but is soon heartbroken to learn that Kevin's only interest is fighting Ben, not seeing his son. Kevin is ultimately defeated by the combined forces of Ben, Ken, and Devlin, to which Devlin, who was kicked out of his family, now hates his father and is later adopted into the Tennyson family after he saves Ben and his son Ken from Kevin's sneak attack. Just before that, Kevin 11,000 was shown to be at the mercy of Ben, as Way Big, who has lost his temper when Kevin injured Ken and Devlin, and proceeds to viscous beat him. However, Kevin (now in his human form) manages to shrug off the attack with little more than a crick in his neck. However, Devlin sneaks up behind him and traps his father in a Null Void Capsule, which he then gives to Grandpa Max, who, before departing, says "I've got a special place for you this time!", indicating that Kevin will be imprisoned in a special high-security prison instead of the Null Void this time. However, considering how many times he's escaped the Null Void, it is very likely that he will manage to escape from his prison.

Ben 10: Alien Force
Kevin comes back in Ben 10: Alien Force, where he was eventually released from the Null Void (he stated in Darkstar Rising that he did his time for his crimes) returned to his human form, and grows into a tall and muscular young man who has rejoined society and reconciled with his family. He has also become an alien weapons dealer, giving him several contacts with criminals (such as Argit, Vulkanus and Sunder the Retriever) as well as a considerable knowledge in alien tech. He has also regained his ability to absorb solid matter.

In his first Alien Force appearance, Kevin attempted to organize a deal between the Forever Knights and the DNAliens in order to sell them level 5 weapons. However, the deal was interrupted by Magister Labrid, Ben and Gwen. Trying to get revenge, Kevin fought Ben, but was easily defeated while the other villains escaped without paying him. Labrid then forced Kevin to help them in finding back the weapon, offering him to avoid problems with the Plumbers then. Though Kevin mainly accepted in order to get his pay, Magister Labrid later sacrificed himself in order to save him from a defective weapon's explosion. This, plus Kevin's interest for Gwen, his promise to Magister Labrid, and his desire to start a better life and become a Plumber like his father, led him to agree to teaming up with Ben and Gwen against the High Breed invasion.

Though he initially still felt a little rancorous toward Ben, Kevin slowly reconciled with him, and he proved to be a valuable ally as well as a good friend. Despite his reformation, Kevin still tends to engage in unethical activities: he is not above stealing gold and jewelry from the Forever Knights and Plumbers equipment from Manny Armstrong and Helen Wheels when presented with the opportunity ("Ben 10 Returns"; "Plumbers' Helpers"); attempts to sell the Rust Bucket to Vulkanus for alien technology, albeit technology he intended to give to Ben (Kevin's Big Score); and conspires with Argit to sell weapons to both sides of a warring race (Simple).



In Darkstar Rising, he reveals that his father was also a Plumber. He never met his father, but his mother told Kevin stories about what his father did. This is a big gap in the original series because in Ben 10, he said that his parents both left him because of his strange electrical powers; this was explained later on in the series as an exaggeration on Kevin's part: Kevin's mother remarried, and in retalliation Kevin destroyed their home which lead to his step-father driving him out of the house. At the end of the same episode, Kevin, along with Gwen and Ben became official Plumbers, after which Kevin leaves to tell his mother about his membership, this suggests that he has now reconciled and rejoined with his family. Also in Darkstar Rising, when explaining that he wanted to be a Plumber for the sake of being just like his father, it "mostly" served as the reason that he joined the Tennysons in the first place (his promise to Magister Labrid and Gwen could be the other reasons).

In the season 3 premiere, Vengeance of Vilgax, Kevin changed clothes and was subjected to a feedback pulse from the Omnitrix after Ben tampered with it. Because of this, he was unable to revert back to his normal human form, instead becoming a living colossus composed of different elements, including steel, taedenite, concrete, and what appears to be wood or quite possibly the stone he absorbed from the cliffs in Inside Man.

Throughout the series he was shown to hate what he had become, to the extent of breaking things off with Gwen, wearing an I.D. Mask in public to appear human, and considering himself a monster. He also discovered that his father Devin Levin, an Osmosian Plumber, was murdered by an alien criminal named Ragnarok, and became bent on vengeance, so much so that he eventually left Ragnarok to his death when he had the chance to save him.



In the series finale The Final Battle, where Vilgax attempted to separate Ben from his friends, Kevin was kidnapped by Albedo in an attempt to split them up. He was also asked by Ben to back him up when taking on Vilgax, which he did. After Ben's Omnitrix was destroyed, he reverted back to human form, revealing that it was the Omnitrix's power that kept him that way.

Ben 10: Alien Swarm
In Ben 10: Alien Swarm, the live-action movie, Kevin is seen driving around with his car. The car is a green 2009 Dodge Challenger. Also he is seen in his human form, with his Season 1-2 clothes and regular absorbing powers. Whenever he absorbs solid objects, his voice sounds distorted. Near the climax he switches to his season 3 clothes revealing that they're a uniform for the garage built on top of a Plumber's base as cover.

Ben 10: Ultimate Alien
Kevin returns in Ben 10: Ultimate Alien, going back to his original Alien Force appearance, clothes and powers. According toUltimate Alien focuses more on Kevin's past, including how he managed to return to his human form, break out of Incarcecon, and escape the Null Void after the original series. Kevin still has the ability to change his hands into different weapons even after he returned to normal in Alien Force.

Kevin and Ben no longer share their famous rivalry and instead have become true friends. Kevin acts as an older brother towards Ben. They care genuinely for each other. Kevin is much more open about his feelings, showing gratitude and tries to express it to both Ben and Gwen. Gwen and Kevin continues their romantic relationship. He also seemed to have a better connection towards his friends' paternal grandfather, Max Tennyson.

In Too Hot To Handle, Kevin is able to repair objects in the current matter he has absorbed by releasing a liquid version of that substance and then hardening it again. He can also manipulate whatever matter he is touching by absorbing it and then morphing it into any shape or form he wants. He uses both abilities when he fixed the broken seal of P'andor's suit, morphed it around his body to trap him, and fused the arms together as makeshift handcuffs.

In Fused, he admits he was selfish when he first met Ben. He also risked his life to save Ben from being taken over by Ra'ad. He also learns that there is another Osmosian named Aggregor. While never explained, Kevin shows sympathy to him because they are of the same race and because Kevin, like Aggregor, was once an insane and violent sociopath due to him having improperly used his powers when he was a child.

In Ultimate Aggregor, he shows his knack for detective work, and later warned by Professor Paradox to remember who his friends are and that things will get worse before they get better. Kevin explains to Aggregor that the reason that he was a villain in the original series is that when Osmosians absorb raw energy, they become insane.

In Map of Infinity, Kevin continues to focus on stopping Aggregor (but not more than Ben), Kevin is easily defeated by Aggregor since his powers have increased, Kevin also seemed to know about the Map of Infinity saying it did not exist, the group go in search of the first part of the Map, Kevin wears a Plumbers' Suit, unlike any other Plumbers' Suits, that Kevin had a little white glove and a circle over the glove (which gives access to Ultimatrix of Ben), possibly this glove is for Kevin to use his powers, he proves to be very strong when a giant hammer crushes the group on a wall,he survived and managed to save the group and remove the hammer from the wall.

In Deep, we see Kevin using a Plumbers' Suit with built-in electrical weapons. His helmet is destroyed, but Gwen uses her powers to make Kevin absorb the matter of his jet, saving him from being crushed by the pressure. However, Kevin still can not breathe, until a Little Fish acts as a "helmet" for him to breathe, in the core Kevin takes the Little Fish from his head (he did not need it since there was air in the core), Kevin also finds and tries to fight Aggregor it to retrieve the second part of Map of Infinity, unfortunately he is easily defeated by the electric powers of Aggregor, Aggregor says that next time Kevin should try absorbing something nonconductive, and runs away with the second part of Map of Infinity, leaving Kevin angry. Kevin leaves the Little Fish (who liked Kevin) in Piscciss and is comforted by Gwen at the end, as he seemed to miss the fish.

In Perplexahedron, When Ben and Kevin get separated from Gwen, Ben says that Gwen can take care of herself and Kevin replies, "That's why I like her." Kevin then talks about his feelings to Ben and how he owes it to them (Ben and Gwen) for putting him on the right path. After finding Gwen (by accident), Kevin tries to say that he likes her, a lot. Then Ben tells her what Kevin's trying to say, and Gwen says, "I know that already." and they kiss, the second kiss in the Gwen/Kevin relationship.

In The Forge of Creation, as a last resort to stop Aggregor from succeeding in his plans, Kevin absorbs the powers and abilities from the Ultimatrix's unlocked aliens, becoming strong and powerful enough to defeat Aggregor. Unfortunately, this also causes him to mutate and become insane once again as Ultimate Kevin. His old desire for power also returns as he absorbs Aggregor's abilities as well. However, Kevin's good heart appears to not be taken over completely, as he accepted 10-year-old Ben's harsh criticism before sparing Aggregor's life, though he declares he will not be so merciful tomorrow. This new form has two-thirds of Jetray's face, right leg, and right half of his crest, one-third of Ultimate Humongosaur's face, Rath's left arm (Swampfire's arm structure), left wrist claw, and left foot (in Jetray's skin color), Lodestar's left shoulder spike and right claw (Diamondhead's arm structure) which can turn into Goop's arm, two of Brainstorm's left legs in place of a lower left arm, Spidermonkey's lower right arm under Diamondhead's right arm, a blue hooded cape modeled after Big Chill's cloak (in The Enemy Of My Enemy, Kevin can wrap the cape around him to form a cloak) that can unfold into a pair of wings and antenna, Humungousaur's tail, chest plates, and head shape, two of Chromastone's purple crystals on his right shoulder in place of Lodestar's right shoulder spike, as well as his pants and hair from his human form (similar to his first mutation). The known powers he has include super strength, able to fly, use Jet Ray's neuroshock blasts, Brainstorm's lighting generation and manipulation, Swampfire's fire blasts and plant manipulation, and Diamondhead's crystal shards and shape-shifting arm, Goop's liquefaction and stretching, NRG's heat rays, Big Chill's intangibility and ice breath, Water Hazard's water blasts, Terraspin's wind blasts, Lodestar's magnetic control, Ultimate Spidermonkey's web spit, and Armodrillo's ground pounding, though it is highly possible that there are many others he has not shown yet.

In Nor Iron Bars a Cage, it is revealed that back during his time in Incarcecon, a prisoner named Kwarrel approached him and offered to help him control his anger and find purpose. Seeing the con as a father figure, Kevin learned how to return to his human form and how his powers could

allow him to absorb matter instead. Kwarrel then showed Kevin a tunnel he had been digging out of the prison to freedom. However, they were ambushed by Morgg who would one day become the warden. Kwarrel held off the guard for Kevin to escape, only to lose his life in the process. Out to avenge his death, even though it went against all that Kwarrel had taught

him, Kevin purposely returned to the prison to kill Morgg. He very nearly succeeded if not for Ben and Gwen's interference. Believing that their friend is truly gone, Ben, much to Gwen's horror, suggests that Kevin must be put down.

In The Enemy of My Enemy, Kevin went after Argit for all the times he

double crossed him. He first attacked him and sent him towards Ben and Gwen. He later attacked the Rust Bucket 3 in order to get Argit, but was forced to retreat due to his car being thrown off the plane. He then attacked the Plumber's Academy and easily took care of theplumbers. He then attacked and thought he killed Argit (due to Argit closing down his vital systems). During his attempt to kill Argit, he nearly kill Gwen, thinking she betrayed him. However, he restrains himself at the last second and spares her life, saying: "The only reason your alive is because of what you used to mean to me." before departing, making is clear that a part of Kevin still cares about her and Gwen remaining adamant that they can still bring Kevin back to sanity without killing him.

In Absolute Power, in hopes of trying to persuade Kevin to rejoin Ben and the gang, Gwen inquires the aid of Darkstar. However, Ben is very furious with the idea. This is Ben and Gwen's last hope of trying to bring Kevin back. Gwen tries to talk to Kevin, who tells her he's been avoiding her because he can't control himself, implying that he doesn't want to hurt her; but he gains the desire to absorb Gwen's powers after taking a "taste".

After Ben defeated Kevin with Ultimate Echo Echo, Cooper finished the machine that would siphon all of the energies that Kevin had absorbed and subsequently cure him with it. Darkstar then betrays the team by using the piece of the Dominus Librium to transfer all said energies into himself, which backfires when Ben;

anticipating such a move, activates a switch to return all of the energies back to where they belonged, Kevin then knocks him out with a punch. Kevin, now back to his human form and of sane mind once again, thanks Cooper. He is then given a passionate kiss on the lips by Gwen (much to the disappointment of Cooper) and gets into a argument with Ben about their previous fight, to which he is relieved that everything turned out alright, after which Gwen asks for their help in explaining to her parents about the damage done to their home, to which Kevin and Ben ditch by voting to go to Mr. Smoothies instead, with Kevin buying.

Energy Absorption
Kevin is descended from a species of parasitic aliens known as Osmosians that dwell on the distant planet Osmos. These aliens have the unique ability to absorb the energy and matter of anything though their body at will and utilize it in various ways.

In Ben 10, Kevin's powers were believed to be an unexplained mutation. During Alien Force, Kevin claimed that his powers were of alien origin. The later theory is proven correct in "Vendetta", were it is revealed that his powers were inherited from his deceased father, Devin Levin, who was a member of a parasitic alien race known as Osmosians. As such, Kevin, like other Osmosians, has the ability to absorb the energy and matter of anything through his body at will and utilize it in various ways. This includes, but is not limited to, electricity (and possibly any energy within the electromagnetic spectrum), the DNA, life force, metabolic energy, and powers of other life forms, fire, water, plasma, and the mass and physical properties of solid matter. Since everything contains either energy or matter, there is no limit to what he can absorb (Kevin clearly stated this in his Alien Force debut ("The good news is since I can absorb anything, I have more than enough power to take you out!").

As seen in Ben 10, Kevin can absorb electricity and use it activate and overload machinery to a minor extent, discharge it as energy blasts, or use it to temporarily boost his strength and his healing capabilities. He can even store energy for periods of time. However, the energy will dissipate over time or though excessive use, so he is required to recharge from a reliable power source.

As revealed "Ultimate Aggregor" and demonstrated in "The Forge of Creation", if an Osmosian were to absorb raw energy (such as the energy of Omnitrix, Ultimatrix, or the Andromeda Aliens after their bodies were converted into energy) and cannot control it, it will cause them to become mentally unstable, which explains Kevin's violent, sociopathic behavior in the original series. As seen in "Escape From Aggregor" and "Absolute Power", Osmosian's are parasitic by nature and feed off the life force and metabolic energy (and subsequently the DNA and powers) of other life forms as their primary form of sustenance. As their primary source of sustenance, absorbing the life force, metabolic energy, and DNA of other life forms keeps their hunger for raw energy (and the subsequent mental instability) latent. However, if they were to absorb raw energy (such as the energy of the Omnitrix or Ultimatrix) and cannot control it, their normal method of feeding turns into an addiction, causing the Osmosian to become mentally unstable and insatiable, forcing them to seek out the largest possible source of energy they can find to feed off of. Storing energy they have absorbed for long periods of time without discharging it properly can also cause an Osmosian to become mentally unstable, as shown in Kevin's debut.

DNA/Life Force/Power Absorption
By absorbing the DNA, metabolic energy, and life force of other life forms, Kevin can temporarily take on another life forms attributes and powers. However, he can only acquire the original creature's powers at 1/10 of their original strength without mechanical aid (this is the biological limit for Osmosians) and can only use them temporarily unless he were to completely drain that life form of all of their DNA and energy, including their life force, leaving behind nothing but a shrunken husk. If he were to absorb the energy from the Omnitrix or Ultimatrix, the raw energy will cause his absorption powers to spiral out of control and subsequently mutate him into a chimerical fusion compromised of most, if not all of the aliens in Ben's current lineup.

In "Framed", it is revealed that Kevin is able to assume any of Ben's starter alien forms at will for as long as he wants without first changing back to human, due to having absorbed sufficient energy from the Omnitrix. Ultimately, due to his young age and lack of experience, his ability to regulate the power failed completely and his absorption powers spiraled out of control, causing him to mutate him into a hulking chimerical behemoth fusion compromised of the ten original Omnitrix starter aliens with no way to revert back to human form. This form includes Kevin's hair, ears (Four Arms' skin), and cargo shorts form his human form, Four Arms' frame, arm count, head, left eyes, torso, legs, and feet, Stinkfly's wings, Upgrade's upper back, Heatblast's left arm, Diamondhead's right arm, Wildmutt's lower arms and gills/nose on his face, Grey Matter's right eye, Ripjaws' teeth, angler (Four Arms' skin), and gills on his torso, Ghostfreak's eye track running along his lower back and torso, and XLR8's tail. The powers he had, or at least showed, from his original mutation made up the major components of his body. The known powers he had include his own ability to absorb matter and energy, Four Arms' super strength, Stinkfly's flight (though he seems to forget he can fly) and slime spit, Heatblast's fire blasts, Diamondhead's crystal projections, shapeshifting arm, and invulnerability, Wildmutt's super agility, senses (as he has Wildmutt's gills/nose on his face), and quills, Ripjaws' glowing lure, underwater breathing (as he has Ripjaws' gills on his torso), and XLR8's super speed and reflexes (though he forgets to use his speed to his advantage) and possibly Grey Matter's super intelligence, Ghostfreak's invisibility and intangibility, and Upgrade's plasma beam (though he did not use their powers during the series as he favors brute force over strategic tactics). He remains in this form for the remainder of Ben 10. According to the enhanced version of "Framed", Kevin's human DNA restores itself over time, allowing him to return to his human form. (Dwayne McDuffie confirmed that during the flashbacks in "Nor Iron Bars a Cage", Kevin had managed to change back to his human form prior to being imprisoned in Incarcecon (which explains why he was wearing jeans instead of cargo shorts) but subsequently reverted back to his mutant form due to his lack of control. Under the guidance of a prison inmate named Kwarrel, Kevin was able to permanently reverse the mutation and learned how to control his anger and powers.)

During "The Forge of Creation", in order to fight the nearly unstoppable Aggregor, Kevin was forced absorbed the energy of Ben's Ultimatrix aliens and later the powers Aggregor stole in ''"Ultimate Aggregor". ''This form

includes his hair and jeans form his human form (similar to his first mutation), Four Arms' frame, arm count, and torso, Jetray's right foot, right half of his face, right half of his crest, mouth, back, and right eye, the left half of Ultimate Humungousaur's face and left eye, a blue hooded cape modeled after Big Chill's cloak that can unfold into a pair of wings and antenna, Humungousaur's head shape, chest plates and tail, Rath's left arm (Swampfire's skin), left claw, and left foot (Jetray's skin), Lodestar's left shoulder spike and right claw (Diamondhead's skin) which can turn into Goop's arm, two of Chromastone's purple crystals on his right shoulder in place of Lodestar's right shoulder spike, Goop's right arm (can transform

into Lodestar's right claw) Spidermonkey's lower right arm, two of Brainstorm's legs in place of a lower left arm, Water Hazard's water ports on his hands, and Ultimate Spidermonkey's split lower jaw (Humungousaur's jaw shape with Jetray's skin). The powers he had include Aggregor's/his own ability to absorb matter and energy, Four Arms'/Manny Armstrong's/Humungousaur's/Ultimate Humungousaur's super strength, Jetray's neuroshock blasts, Big Chill's ice breath, flight, and intangibility, Rath's wrist claw and aggression, Swampfire's fire blasts, seed bombs, and plant manipulation, Lodestar's magnetism manipulation, Diamondhead's crystal projections, shapeshifting arm, and invulnerability, Chromastone's ultraviolet blasts, Goop's liquefaction and stretching, Brainstorm's electric blasts, telekinesis, and force fields, Ultimate Spidermonkey's web spit, Echo Echo's sonic scream, Water Hazard/Bivalvan's water blasts and invulnerability, Armordrillo/Andreas's jackhammer arm, Terraspin/Galapagus's wind blasts, NRG/P'andor's heat rays, AmpFibian/Ra'ad's levitation, Heatblast/Alan Albright's pyrokinesis, XLR8/Helen Wheels' super speed and reflexes, Pierce's spike generation, Benvicktor/Dr. Vicktor's lightning generation and redirection, and Charmcaster's Stone Creatures/Gwen Tennyson's manna blasts. He can also use the Map of Infinity to travel to any desired location as he absorbed it when he absorbed Aggregor's energy and powers at the end of "The Forge of Creation". (confirmed by Dwayne McDuffie). At the end of "Absolute Power: Part 2" though the combined efforts of Ben, Gwen, Cooper, and Darkstar, Kevin was cured of his mutation using a fragment of the Dominus Librium, thus regaining his sanity and humanity and returning the powers he absorbed to their rightful owners.

Matter Absorption
In Ben 10: Alien Force (five years after the original series), Kevin returns in human form with his absorption powers intact. However, he is now also able to absorb the properties of materials into his own being (e.g iron, copper, rock, nickel), transmuting himself into a living form of whatever material he has absorbed and subsequently use it to proportionately increase his physical strength and durability. It is revealed in the episode All That Glitters that the transmutation actually serves as a second skin/coating that eventually peels away as he takes damage. However, while fighting a Techadon, the war robot blasted a hole straight through Kevin in rock/concrete form, but he demonstrated minor regenerative abilities by absorbing metal to cover the hole. In the episode Plumbers' Helpers, Kevin can absorb multiple materials at once, as demonstrated by absorbing both nickel, copper and zinc (from loose change in his pocket). He requires a decent amount of material to completely encase himself (objects the size of marbles are only able to produce a coating large enough to cover one of his wrists while a Taedenite crystal twice the size of his hand is sufficient to coat his entire body). This ability has once been used productively when Kevin was forced to synthesize a coating of a living gem known as Taedenite, thus incapacitating him; Vulkanus mentioned that it's the rarest gem in the galaxy, and with the amount he chipped off from Kevin he was able to buy a permit to "renovate" the Earth, and Paradox mentioned in Vilgax Attacks that with the amount Vulkanus chipped off of Kevin he has the largest stash in the galaxy.

In the Alien Force season 3 premiere, Kevin loses the ability to revert to his human form after a feedback blast, caused when Ben tampers with the Omnitrix and Kevin tries to remove it to help Ben, turning him into a living colossus composed of the various solid matter he had absorbed, including steel, Taedenite, concrete, and stone. In addition, Kevin's previous super strength and durability is further enhanced and he gains limited regenerative and shape-shifting abilities, seen when he shifts his limbs into a variety of different tools, such as a mace, a hammer, a sword, and large clippers. In The Final Battle: Part 2, he was turned back to normal and got his old powers back after the Omnitrix self-destructed. In Ben 10: Ultimate Alien, Kevin still retains his regenerative and shape shifting abilities after his mutation is reversed due to him now having knowledge of being able to doing so.

In Too Hot To Handle, Kevin's abilities have shown to develop more, allowing him to repair objects of the current material he has absorbed either by turning it into a liquid or releasing a liquid version of whatever material he has absorbed. While absorbing matter, he can momentarily merge with the actual matter and manipulate the substance he has absorbed. Both abilities were used when he repaired the rock ceiling of a mine, fused the seal of P'andor's suit, morphed it around P'andor, and fused the arms together as makeshift handcuffs.

Other Skills
Even without his powers, Kevin is shown to be far stronger than a baseline human. While not to the same extent as aliens like Fourarms and Diamondhead, Kevin has repetitively shown to be able to lift and throw the combined weight of several people and and resist impacts and physical trauma that would severely injure an ordinary person with moderate discomfort.

Kevin also has some noticeable skill in martial arts which he gained during his years as a runaway, a prisoner in Incarcecon, an alien tech dealer, and a member of the Plumbers. Even when he was only eleven, Kevin proved on several occasions to be a highly formidable fighter, having held his own against and defeated opponents such as the Megacruiser robots, Technorg, and even Vilgax in a one-on-one fight, something that Ben has never accomplished.

Despite lacking a proper formal education, Kevin possesses a vast scientific and technological knowledge of alien paraphernalia; he even once

mentioned that he learned Astrophysics on the streets. Not only does he have a great knowledge in technology, he also has great deductive skills, having been able to determine specifically what happened in a battle between Aggregor and the Plumbers several hours after the battle, greatly impressing his friends and even gaining a compliment from an experienced Max.

In episode Deep, when Kevin, Ben, and Gwen travel to planet Piscciss, an event occurs when a large sea creature attacks their ship and steals Gwen. Ben and Kevin both argue that they both cannot use their powers while being in their plumber suits. So Kevin made some alterations to the suits, equipping them with propelling units and neural shock pulses that allow them to attack with electric shocks with every blow they make.

Kevin is a very good driver, being able to race and chase in his car and the

Rust Bucket 3. He is a skilled driver both on land or air. Racing is one of the things he's fond of as in Paradox, it is said that he often drag race at night on the out skirts of Los Soledad for fun. This is also shown as he collects speeding tickets and is fond of holding his own personal record much to Gwen's dismay. Sometimes Ben is bothered by Kevin's very fast driving, hoping he could drive on his own. Kevin is great at mechanics. He is shown to repair his car for the numerous damage it took during the course of the series. He also modified his car, setting alien tech for beneficial gears. A running gag in the series is how Kevin's car gets damaged or destroyed in one way or another during battle (Kevin even said during a fight with Sunder "What is it with everybody wrecking my car?!" after Sunder damaged the hood of his car with his axe). On top of that he built the DX Mark 10, a car that he (reluctantly) gave to Ben as his sixteenth birthday present.

Gwen Tennyson
When they first met, Kevin was a renegade eleven-year old, who knew Gwen as Ben's smart-mouthed cousin. In Kevin 11, Gwen says she does not like Kevin, and that he is just trouble, and Gwen and Kevin do not show any interest for each other. He later had an vengeance against Ben and almost burnt Gwen in the episode Framed. In Back With a Vengeance, Kevin holds Gwen hostage so that Ben would give up the Omnitrix. Gwen tries shooting Kevin, but he grabs the blast, making it slant backwards and hit Gwen, causing her to scream. Ultimately he gets trapped in the Null Void.

During the series it is evidently displayed that Gwen feels sorry for Kevin having to live the hard life such as in Perfect Day and other encounters they have. There was not much or barely any interaction between the two though.

In Ben 10: Alien Force, there was instant chemistry. Gwen's previous pity and admiration of Kevin turned to infatuation then love. In the first two seasons we see the two falling for each other. The problems they have or issues did get in the way because both of them cared about each other. In What Are Little Girls Made Of?, Kevin did not want Gwen to go to Anodyne to learn how to fully master all of her Anodite and magical powers and abilities, leaving him and Ben behind.

The two also work well on the battlefield. Whenever Gwen was knocked down in a fight Kevin would automatically be by her side helping her up and so otherwise. Both of them would also put their life at risk in order to protect the other. Arguments between Kevin and Gwen are quite unique. Shouts were rare but instead talking sternly but quietly in each others face makes up for it. In Darkstar Rising, Gwen tries to comfort Kevin for his father's absence and his stripped privilege. The two almost kiss until a Highbreed barged in. Their relationship grows in the second season. They danced together in Save the Last Dance. When Kevin gets mutated after he and Ben try to hack the Omnitrix, he tries to break off things between himself and Gwen during his bouts of self-consciousness. Kevin was quite depressed, he also gave Gwen a "keep me in your memory" locket telling her to remember his old self before the accident in Fool's Gold. His appearance didn't bother Gwen but it proves just how much he cares about it. As seen in the episode In Charm's Way, Kevin still strives hard, though he vents his frustration in the wrong way (on Gwen) thus falling for Charmcaster which made conflict. In the end, Ben informs Kevin that Gwen has been working day and night, and going through every spell book to find a cure for him, leaving him to regret getting mad at her. However, he tries to make it up to her by saving her from Darkstar in Trade-Off leaving him from human form into his mutation. Gwen though still cares for him just as much such as in Time Heals and Vendetta where she would go to desperate measures to make things up. In The Final Battle: Part 2, after Kevin returns back to normal, they share an on-screen kiss.

In Ben 10: Ultimate Alien, for the first few episodes, they both do not show much interaction, and have a lot of arguments such as in "Video Games" and the early episodes. However, things got settled and changed in the episode Too Hot To Handle after Gwen gets hit by P'andor's blast, he quickly held her, helping her get up, and told her not to ever do that to him like that again. Later on the episode, he made Gwen leave the power plant because he's worried about her. In Fused, after Gwen casts the spell, she nearly fainted and landed on Kevin's lap. There was some obvious eye contact too. In the episode Hero Time, it is shown that Gwen does not approve on Kevin falling for other girls instead of her. For example, Gwen threateningly told Nocturne that she would "peel her like a grape" after seeing Kevin quite happy of Jennifer thanking him for saving her life. In the episode Ultimate Aggregor Kevin kissed Gwen on the cheek after she took him to one side to talk to him, when Kevin reveals the insanity of Osmosians when they absorb energy, Gwen discovers that absorbing too much energy was the reason for Kevin's beserk and criminal behavior when he was an eleven-year-old child.

In episode eleven Map of Infinity Gwen is defeated by Aggregor and Kevin help she, soon Kevin is defeated too, when the two up, the two embrace, Ben, Gwen and Kevin are in search of the Map of Infinity, where Gwen collapses under a gate that Ben and Kevin are holding the two despairing, just Aggregor takes the first fragment of the map, and Kevin saves Gwen. In episode fifteen "Perplexhahedron", Kevin says he wants to take care of her in front of Swampfire and admits he likes her. And after Swampfire freed Gwen from the ice, she and Kevin kiss. Then Swampfire says in disgust "Why don't you two get a room?!" In "The Forge of Creation", and "Nor Iron Bars A Cage", it is shown that Gwen still has not given up on Kevin, despite his current situation.

In episode eighteen, The Enemy of My Enemy, Gwen is determined to reach Kevin's human heart. She stops him from killing Ben, and yells at him for brutally injuring Argit, telling him that is enough, horrified that he would do such a thing. Kevin attacks her and is about to kill her as well with fire, but stops himself at the last second. He tells Gwen that the only reason she is alive is because of what she used to mean to him. He than phases through the ceiling into space, leaving Gwen with tears in her eyes,showing that he still cares for her.

In the two-part first season finale Absolute Power: Part 1 and Absolute Power: Part 2, Gwen is more determined than ever to restore Kevin to his normal self, attempting to talk him out of his rage and insanity several times to no avail. She even risks her a fraction of her Anodite and magical abilities when Kevin tries to prevent himself from his hunger of absorbing energy. But his need for energy overwhelmed him in the end. Kevin is restored to his normal self with the help of Cooper, who is given a kiss on the cheek from Gwen as thanks, only for Kevin to sarcastically reply in return "since your kissing people..." while pointing at his face. They share a romantic kiss as a result, celebrating in the return of the normal Kevin Levin.

Jennifer Nocturne
Jennifer Nocturne was a 19 year old teenage actress. Kevin admired not just liking her skills but also herself. He introduced himself just before she took Ben to the party, but she paid little attention saying, "Oh of course you are." Later when Nocturne was kidnapped and saved by Kevin and Gwen, Nocturne asked Kevin to be her boyfriend, Gwen threatened to peel her like a grape.

Trivia

 * Kevin has shown a willingness to kill, most likely attributed to his own harsh life.
 * Kevin has mutated three times in all three series. First from the original Ben 10, then again in Ben 10: Alien Force and most recently in Ben 10: Ultimate Alien. In all three mutations that Kevin has endured, he has only become insane during his first and third mutation. This is because during the first and third mutations he had absorbed energy, which causes Osmosians to go insane.
 * Dwayne McDuffie confirmed that Kevin, like all Osmosians, is stronger than an ordinary human and is even more resilient to damage even without absorbing matter or energy.
 * Dwayne McDuffie confirmed that Kevin had every power that Ben unlocked in his Ultimatrix during his third mutation and that "he just never got around to using the hundreds of powers he absorbed".
 * Despite having proficiently good skills in unarmed combat, Kevin has been shown to lack creativity and is rather ignorant with his array of powers during his first and third mutations, relying only on the abilities that had the most strength. Kevin shares this behavior with Ben and it wasn't until he realized the possibilities of his powers that he was able to become more creative in using them to a much greater and dangerous degree.
 * Kevin's car is faster than Ben's as shown in the episode The Transmogrification of Eunice.
 * Kevin loves watching soap operas.
 * Kevin did not become insane in Alien Force because he didn't actually absorb the energy feedback of the Omnitrix; rather the Omnitrix rewrote his Osmosian DNA when he and Ben tampered with it to unlock the master control.
 * Kevin and Gwen have kissed three times on screen. Twice in Ben 10: Ultimate Alien and once in Alien Force.
 * Kevin's full name is Kevin Ethan Levin, as shown in War of the Worlds: Part 1.
 * Kevin's original hometown is Bellwood, but he ran away to New York after destroying his family home.
 * Kevin is the first villain in the series to be of Osmosian descent (though he is technically half-Osmosian). The second is Aggregor, who is a full Osmosian.
 * Kevin's very first crime was stealing a bike and used it to run away to New York. The padlock to it he wore on his neck as a souvenir.
 * Kevin is shown to still have family; his mother and step-father.
 * The black rings Kevin had around his eyes in the original series appear to be a sign that an Osmosian has recently absorbed energy, as he no longer had them after he started absorbing solid matter. This is further evident in Ultimate Alien, as Aggregor (an Osmosian warlord who regularly absorbed raw energy) had similar ones around his eyes as well. They may be bags, which may be caused by too much energy, sort of like by not getting enough sleep in reality.
