Kevin Levin (Classic)

Kevin Ethan Levin, AKA Kevin 11 AKA Kevin E. Levin, is a half Human /half Osmosian with the ability to absorb any type of energy or matter and release it 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.

Ben 10
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. Eventually, Ben breaks off their partnership when Kevin rigs two trains (one carrying money and one carrying people) to collide, not caring that hundreds of innocent people would be killed. Ben became Heatblast to stop Kevin, but to even the odds, Kevin grabs onto Heatblast and absorbs his powers, changing him into an incomplete version of Heatblast. When Ben foils Kevin's plans and escapes, Kevin leaves to use his new powers to get revenge on the bullies that picked on him. But Kevin's new powers disappear and changes back to his regular form. When Ben shows up as Fourarms to stop Kevin, Kevin absorbs Fourarms' power and changes into an incomplete version of Fourarms. 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 Los Angeles, 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: Fourarms' head, body, left eyes, legs and feet, Grey Matter's right eye, Upgrade's upper back, Heatblast's left arm, Diamondhead's right arm, Wildmutt's arms below them, XLR8's tail, Stinkfly's wings, Ripjaws' antenna, gills, and teeth and Ghostfreak's black lines running along his chest. Because of this, Kevin fights Ben and as he was about to kill him, Lt. Steel from the Special Alien Capture Team shoots him into the water and is presumed dead, but at the end of the episode, he is revealed to be alive because the water bubbled which meant he was breathing because he had Ripjaws's ability to breathe underwater.

After his mutation, Kevin gloats that he has all of Ben's powers plus his own, making him Kevin 11"(the name' Kevin is credited under in the ending sequence of the show). He has Stinkfly's ability to fly and his slime spitting. Diamondhead's diamond ability with his right arm. Fourarm's strength. Wildmutt's sniffing ability. XLR8's speed. Heatblast's ability to shoot fire out of his left arm. Ripjaw's bitting and unhingeable jaw(possibly also his ability to breath under water because he has Ripjaw's gills), and Upgrade's laser vision. Although Kevin does not have all of the powers of the Omnitrix aliens he copied. He does not have Grey Matter's intelligence, Upgrade's ability to take control machines, and Ghostfreak's ability to turn invisible and his ability to walk through walls. Despite Kevin's claim, Ben notes that Kevin's powers are only one-tenth as strong, as seen when Diamondhead was able easily catch and crush with his bare hands, the Petrosapien projectiles Kevin fired at him (This assestment is proven correct in Ultimate alien as Aggregor stated that when Osmosian's absorb the life force of other beings they only gain 1/10th of that being's powers) and Kevin never exhibits his original power in this form.

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 pinned him to the wall with Stinkfly goo before moving in with a Diamondhead spear, gloating that no matter what Ben transformed into, he knew every one. Little did he know that Ben had discoverd there were more aliens in the Omnitrix and had unlocked Cannonbolt, who 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, who 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 advanced edition of the episode, after beating Kevin, Technorg left the ship to return to his homeworld 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 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 in Ben's school. In the dream, Kevin was human but then changed into his mutated form (which appeared uglier than it used to be probably a exaggeration of Ben's fear of Kevin) and fought Ben. When Ben takes control of the dream, he is able to defeat the dream version of Kevin in one fell swoop.

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 reconcilied with his family. He has also become an alien weapon dealer, giving him several contacts with criminals (such as Argit, Vulkanus and Sunder the Retriver) as well as a considerable knowledge in alien tech. He has also come back to his human form and gained the ability to absorb solid matter.

In his first Alien Force appareance, 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 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 sacrified himself in order to save him from a defective weapon's explosion. This, plus Kevin's interest for Gwen and his desire to become a plumber like his father was, led him to agree in teaming up with Ben and Gwen against the HighBreed 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.

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 but it may have only been an exaggeration on his part, since it is slightly hinted that Kevin's mother remarried, due to him saying, "My father... my real father." It's is also possible that after the death of his father, his mother couldn't cope and Kevin then somehow ended up in foster care, and that it was these parents that left him.

At the end of the same episode, Kevin, along with Gwen and Ben become 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. 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). It was clearly implied his mother remarried after his real father's death, which could explain why he was kicked out of his house when he was 11.

In the season 3 premiere, Vengeance of Vilgax, Kevin changes clothes and Kevin is subjected to a feedback pulse from the Omnitrix after Ben tampers with it. Because of this, he is unable to revert back to his normal human form, instead becoming a mixture of different elements.

Throughout the series he is shown to hate what he was 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 discovers that his father Devin Levin, an Osmosian Plumber, was murdered by an alien criminal named Ragnarok, and becomes bent on vengeance, so much that he eventually left Ragnarok to his death when he had the chance to save him. This episode confirms that he has reconciled with his mother at last, and that he has few moments of his father.

In the series finale The Final Battle, where Vilgax attempts to separate Ben from his friends, Kevin is kidnapped by Albedo in an attempt to split them up. He is also asked by Ben to back him up when taking on Vilgax, which he does. After Ben's Omnitrix is destroyed, he reverts back to human form, revealing that it was the Omnitrix's power that kept him that way. Because of this, Kevin and Gwen share their first on-screen kiss.

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. Also when he absorbs the solid objects, his voice sounds distorted. Near the climax he switch to his season 3 cloths revealing that they're a uniform for the Garage built on top of a plumber's base a cover.

Ben 10: Ultimate Alien
Kevin returns in Ben 10: Ultimate Alien, going back to his original Alien Force appearance, clothes and powers. According to Dwayne McDuffie, part of the series might feature more about his past. Kevin still has the ability to change his hands into different weapons even after he returned to normal in Alien Force. In Too Hot To Handle, Kevin is able to repair objects in the current subject he absorbed at the moment by turning it into a liquid and then hardening it. 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. Also, Kevin has secrets which will be revealed in the new TBA episode of Ben 10: Ultimate Alien, which will be on October 10th, 2010.

Gwen Tennyson
When they first met, he was a renagade 11 year old, who would later have a vengeance aimed at Ben. He also almost smashed her and burned her in the episode, Framed

In Ben 10: Alien Force, there is instant chemistry. When Kevin gets mutated after he and Ben try to hack the Omnitrix, he cuts things off between them during his bouts of self-consciousness. In The Final Battle: Part 2, Gwen and Kevin share there first kiss on-screen. In Ben 10: Ultimate Alien, having returned to his normal form after the destruction of the Omnitrix and they resumed their relationship. Kevin is still Gwen's boyfriend and he has been her boyfriend for the longest. In the episode Hero Time, it is seen that Gwen does not approve of Kevin falling for other girls instead of her. For example, at the end of the episode, Gwen says threateningly to Jennifer Nocturne that she'll peel her like a grape after seeing Kevin appear quite happy of Jennifer thanking him for saving her life.

Powers and Abilities
Kevin's abilities have somewhat changed through out the course of the series. Generally, his power revolves around absorption, either of energy or matter. In Ben 10, Kevin can absorb energy and manipulate machinery to a minor extent though the energy he uses is finite, so is required to steal more. By absorbing energy from the Omnitrix, Kevin can temporarily take on attributes of any alien form Ben has currently taken on.

In Framed, it is revealed that Kevin is able to assume any of Ben's alien hero forms at will, due to having absorbed enough sufficient energy from the Omnitrix. Despite this advantage over Ben, he is still defeated. The rage causes his absorption power to spiral out of control, mutating him into a hulking behemoth fusion compromised of the ten starter Omnitrix aliens with no way to revert back to human form. 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.





In Ben 10: Alien Force (5 years after the original series), Kevin returns in human form with his absorption powers intact. However now, he is able to absorb the properties of material into his own being(e.g iron, copper, rock, nickel) transmuting himself a living form of whatever material he has absorbed and use it to increase his physical strength. 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. This ability has once been used productively when Kevin was forced to synthesize a coating of a living gem known as Taedinite, thus incapacitating him, Vulkanus mentioned that it's the rarest gem in the galaxy with the amount he chipped off from Kevin he was able to buy a permit to "renovate" the earth and Paradox mentioned that with the amount Vulkanus chipped off Kevin.

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 but instead got a blast of feedback, imprints various materials onto him, such as concrete, metal, wood, and what appears to be Diamondhead crystals or quite possibly Taedenite crystals from "Kevin's Big Score". In addition, Kevin gains enhanced strength and endurance and limited shape shifting abilities, seen when he shifts his hands into a variety of different tools, such as a mace and large clippers. He is also knowledgeable about alien technology(e.g. In Primus, he states that Techadons are mass produced war robots). 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 has shown to be able to still shapeshift his arms into weapons after his mutation is reversed. Dwayne McDuffie revealed the reason for this is due to now having knowledge of how. In Too Hot To Handle", Kevin's abilties have shown to develop more, allowing him to manipulate whatever substance he has absorbed, as shown when he repaired the rock ceiling of a mine, refused the seal of P'andor's suit, and when he morphed it around him and fused the arms together as makeshift handcuffs.

In addition to his powers, Kevin, as of Alien Force, has gained a considerable knowledge about alien tech thanks to his time in alien black market, making him the team expert in this area.

Absorbing
Kevin can absorb metal, wood, ground, crystals an much more, in darkstar rising when he transformed back into his original self he was powerless.

Trivia

 * Although it looks like Kevin has black hair, it is really raven-colored.
 * In the Alien Force season 2 finale War of the Worlds: Part 1, it is revealed that Kevin's middle name is Ethan, making his full name Kevin E. Levin, officially connecting the pun to his old nickname "Kevin 11". Ben finds this extremely hilarious, saying that he has lost "all remaining pretense of cool".
 * He is part osmosian. Even though his parents supposedly abandoned him (this may be a lie Kevin invented to impress Ben, because he doesn't answer to anybody) Kevin still has a mother as shown at the end of Darkstar Rising, when he tells Ben and Gwen that he will tell his mother about his new plumber's badge, and at the beginning of Vendetta, where Kevin's mom made her first appearance on the show.
 * Kevin has been unable to transform back to his human form twice now. Both times were from tampering with the Omnitrix.
 * Like Ben, Kevin is a big fan of Sumo Slammer, as he is thrilled when Ben tells him there is going to be a Sumo Slammer Movie (in the episode Vengeance of Vilgax: Part 1), though later he calls it boring and acts as if he had never seen it(however its possible that he isn't familiar with or is a fan of the TV Show, and is a fan of the video game). He also may have grown out of it (but is still fond of the idea of a Sumo Slammer Movie). It is notable that the first time Ben and Kevin worked together in Kevin 11, they attempted to break into a warehouse to steal the new, unreleased, Sumo Slammer video game together.
 * In Con of Rath, during a battle with Vulkanus he reveals he has dreams where he is confronted by his old enemies(or everyone he ever knew) and try to hurt him. He mistakenly assumes that everybody has dreams like that, only to discover he was mistaken when Gwen says, "I don't have dreams like that."
 * Strangely, Kevin's hometown is Bellwood also, same as Ben's even though in the episode Kevin 11 he lives in New York City.
 * Kevin was stuck in his mutation in Alien Force because of the Omnitrix. After the Omnitrix has self-destructed, he was turned back to normal.
 * Kevin's powers are similar to the Marvel villain, the Absorbing Man. However, unlike him, Kevin only becomes a solid form of what he absorbs, coating him with a protective layer of said material. The Absorbing Man was actually able to become what he touched and manipulate his new form anyway he wished. Additionally, during the time Kevin had mutated, he was similar to the DC hero, Metamorpho. Both had the ability to reshape their bodies as they wished, being comprised of different elements that can be manipulated. However, Kevin was only solids, while Metamorpho was liquids and gases in addition to solids. Kevin could not also change his body to different elements while Metamorpho could. Interestingly, Kevin shared Metamorpho's insecurities and self-hatred of their mutated appearance.
 * In Ghost Town, Kevin says that he is a fan of Whack-a-Mole.
 * In the original series when Kevin was a mutant combo of Ben's 10 starters, he did not appear to have the powers of Grey Matter (size and intelligence), Upgrade (melding with technology), and Ghostfreak (Invisibility and Intangibility), although their body parts can seen on him possible being almost useless at 1/10 of their powers.
 * It appears that Kevin doesn't go to school like Ben and Gwen(however this may be due to him being older than Ben and Gwen).
 * Technically, Kevin was first Osmosian villain (as well as the first Osmosian to appear) in the Ben 10 series (though he is only half-Osmonsian), with second being Aggregor (who happens to be full Osmosian).
 * According to Aggregor, Kevin is considered a "hatchling" to Osmosian.
 * When Kevin forms things out of his hands he remsembles another creation by "Man of Action," Generator Rex.
 * Kevin doesn't like Michael Morningstar for certain reasons involving his love life with Gwen.
 * Kevin and Gwen's relationship is populer among many fans and is most usually refered to as "Gwevin."
 * When Kevin returns to his human form in Trade-Off and The Final Battle: Part 2, he is seen with black briefs.
 * Kevin still has the power to absorb any type of energy or matter and release it at will, but doesn't want to because of it's previous side-effects.
 * According to an Ultimate Alien comic which was found in a K-Zone magazine, Kevin mentions that he hates wearing green jackets, but he is shown wearing a dark green jacket in Everybody Talks About The Weather.
 * In the episode Darkstar Rising, Kevin said that he had never met his dad, but in Vendetta, he is shown in a picture with him.
