Kevin Levin (Classic)

Kevin Ethan Levin is a human-alien hybrid with the ability to absorb any type of energy and release it at will, though he seems only able to release electricity, or he may simply favour this due to its offensive potential. The energy can be used to activate or overload various machines and can also be used to make energy blasts. Dwayne McDuffie, one of the Alien Force writers, has confirmed that Kevin is in fact half human and half alien, an Osmosian (play on osmosis) to be precise. It is unknown which one of his parents was an alien.

Ben 10
Kevin was abandoned (he ran away from home before the start of the series due to his falling out with his parents) before the start of the series due to his powers, and has been alienated ever since; this has led to him developing anti-social behavior disorders that border on sociopathy. However, he is reformed over the course of Ben 10 Alien Force, and rejoins society and apparently reconciles with his family. When absorbing energy from the Omnitrix's aliens, he becomes an incomplete, but effective, version of that alien. In his first appearance in "Kevin 11", he is first encountered by Ben Tennyson in an arcade, where 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) to collide, not caring that hundreds of innocent people would be killed. He then absorbed the abilities of Heatblast and Fourarms, using the former form's powers to get revenge on those who had wronged him. He absorbed the latter form's powers during his second battle with Ben to even the odds. After trying to take the Omnitrix from Ben, the Omnitrix emitted a feedback pulse to prevent Kevin from taking it, seemingly neutralizing his power. Kevin, however, exhibits the ability to create flame at the end of the episode.

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 and legs, Grey Matter's right eye, Upgrade's upper back, Stinkfly's wings, Diamondhead's right arm, Heatblast's left arm, Wildmutt's arms below them, Ghostfreak's lines, XLR8's tail and feet, and Ripjaws' antenna, gills, and teeth.

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. Diamond Head'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 (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, (although this assessment may not be accurate) and Kevin never exhibits his original powers in this form (the same is true for Ghostfreak, Upgrade (

During his third appearance in "Grudge Match", Kevin attacks Ben to get revenge, blaming his condition on Ben. As the two battle, they are abducted and forced to fight in Slix Vigma's gladiator games. During their battles, Ben helps Kevin to realize the advantages of his mutated form. Because Kevin 11 is an amalgam of aliens, he can mix and match their powers to make up for their reduced potency. Although forced to work together, Kevin's only goal was killing Ben. He is transported to a different galaxy at the end of the episode while locked in combat with Technorg, who beat him then escaped. He then took the ship as his own.

Kevin returns in the episode "Back With a Vengeance", where he teams up with Vilgax to defeat Ben, and eventually manages to remove the Omnitrix. However, he betrays 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.

Ben 10: Alien Force
In the BEN 10 series his name is Kevin 11. But in the new series his name is Kevin E. Levin. vealed in the episode "The Gauntlet", Kevin, as mentioned by JT, is now reputed as "the toughest kid in town", indicating that he has taken up residence in Bellwood although this has never been explicitly stated, nor is it mentioned how he could've escaped the Null Void. It is worth noting that when Ben first defeated Kevin, he offered Kevin to join their group; a similar thing happened at the begining of Alien Force, when Ben defeated Kevin as Swampfire and he was once again offered to join them, this time he took it.

In "Darkstar Returns", 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 he had somehow ended up it 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) Dwayne Mcduffie confirmed that Kevin was actualy kicked out from his home after a violent incident with his parents.

In the season 3 premeire "Vengence of Vilgax", Kevin is subjected to feedback 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. In busy box the box is stronger than kevin which means it is unknown if this made his body become a mixture of the elements he has absorbed or if this fused the materials around him to his body, though it's most likely the former.In 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. It was revealed in "If All Else Fails," that Kevin's father was named Devin. He is also become very muscular. Whenever he's shirtless, it reveals huge arms, big pecs, and slight abs.

Kevin's Abilities
Kevin's abilities have somewhat changed through out the course of the series. Generally, his power revolves around absorption. 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, minus Ghostfreak. He remains in this form for the remainder of Ben 10. According to the enhanced version of "Framed" Kevin's human DNA restores through time. So, after 5 years he will become a human again.



In Ben 10: Alien Force (5 years after the Ben 10 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 such as metal or rock, transmuting himself a living form of whatever material he has absorbed and use it to increase his physical strength. Kevin learned to control his new absorbing powes in the Null Void (Confirmed by Dwayne McDuffie). 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. 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). Dwayne McDuffie stated that Kevin can, in fact, still absorb energy, but is "afraid to", a plausible reason, considering his previous mutation. He requires a decent amount of material to completely encase himself. This abiltiy has once been used productively when Kevin was forced to synthise a coating of precious material, with the coating thickening after multiple absorbtions to the point where Kevin couldn't move. 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, imprints various materials onto him, such as concrete, metal, wood, and what appears to be Diamondhead crystals or quite possibly Taedenite crytals from "Kevin's Big Score". In addition, Kevin gains limited shapeshifting abilites, seen when he shifts his hands into a variety of different tools, such as a mace and large clippers. It is unknown if this is a permanent condition, simply temporary, or a life cycle of the Osmosians simply accelerated by the Omnitrix.

Trivia

 * In the Ben 10: 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 Eleven". Ben finds this extremely hilarious, saying that he has lost "all remaining pretense of cool".
 * He is part alien. 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.
 * Kevin has been unable to transform back to his human form twice now. Both times were from tampering with the Omnitrix.
 * It is shown in "Darkstar Rising" Kevin dislikes smoothies.
 * 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 [[Force Vengeance of Vilgax: Part 1).
 * After his mutation in season 3 of Alien Force it is shown Kevin uses an I.D. mask to look normal.
 * In "Trade-Off", Kevin is shown to have worn black briefs.
 * 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."
 * Despite his heroic actions in Alien Force, Kevin has been shown to occasionally engage questionable actives, from minor crimes like speeding, to helping his old partner Argit sell weapons to both sides of an alien war (for a cut of the profits), that Ben was trying to end in the episode "Simple". This makes him sort of an anti-hero.
