Kevin Levin (Classic)

Kevin Ethan LevinWar of the Worlds: Part 1 is an Osmosian and a member of Ben's team. When Kevin first appeared in the Original Series, he quickly became one of Ben's most notable enemies. However, he reformed in Alien Force and became one of the main heroes of the franchise, until his departure with Gwen in The More Things Change: Part 1.
==Appearance==
===Regular Appearances===
In the Original Series, Kevin was a thin and scrawny boy with shoulder-length black hair, pale skin, and dark brown eyes with black-discolored marks around them. He wore a torn black T-shirt, black studded armbands, brown cargo shorts, black boots, and a padlock necklace which is a spoil from his first crime: stealing a bike and using it to run away to New York.
In Alien Force, Kevin had grown into a tall and muscular young man. His eyes lacked the black marks. His normal attire in Season 1, as well as Ultimate Alien, was a tight black T-shirt over a grey long sleeve shirt, blue pants, and black combat shoes. His hair, although still long, was styled into a choppy mullet.
In Season 2 of Alien Force, he wore a short-sleeved light blue oil-stained mechanic's jacket over a white muscular shirt, blue pants, and his black combat shoes. After being mutated, he occasionally used this appearance as a disguise via an ID Mask.
In Omniverse, Kevin wore the same black shirt, but the sleeves and collar were roughly cut, his grey shirt has stripes, the sleeves on his long-sleeved grey shirt were slightly torn and he wore blue holsters. His hair was longer and straighter, and his pants had a small tear below the left knee. He also wore a padlock necklace similar to the one he wore when he was 11 but marked with an "11". He also sported black marks around his eyes again.
In Weapon XI: Part 2, Kevin gets the same cross-shaped scar to his chin that his future self has.
12-year-old Kevin in Omniverse looks exactly the same as how he does in the Original Series, except for his cargo pants being grey instead of brown and his padlock necklace being marked with an "11".
===Occasional Appearances===
As shown in a fake photo in Vendetta, as a 3-year-old, he wore a white T-shirt.
In Everybody Talks About the Weather and The Perfect Girlfriend, he wore a green jacket.

In Save the Last Dance, he wore a black tuxedo with a black bow tie.
In Birds of a Feather, when on the Moon, he wore an orange spacesuit with four arms.
In the beginning of Alien Swarm, he wore a dark grey jacket over his regular attire. While investigating Ship-It, he wore a beanie with this outfit. Later in the movie, when revealing the Mark 10 to Ben, Gwen and Elena, he wore a short-sleeved bluish black mechanic's jacket with a white name tag that had "Kev" on it.
In Trade-Off! and The Final Battle: Part 2, he wore black speedo-like swim trunks when he turned back to human. 
In the flashback in ...Nor Iron Bars a Cage, 11-year-old Kevin looked the same as he did in the Original Series, but with blue jorts instead of brown pants.
In Ultimate Alien, he wore a standard Plumber suit during a few of his off-world excursions.
In Escape From Aggregor, he wore a pale blue winter coat and blue pants.
In Absolute Power: Part 2, he wore blue pants after he turned back to human. 
In Basic Training, while at the barracks in the Plumbers' Academy, he wore an olive tank top and black shorts.
In The Perfect Girlfriend, while stalking Elena disguised as Julie, he wore the green jacket he wore in Everybody Talks About the Weather and blue-tinted glasses.

==Personality==
Due to a complicated childhood and having supernatural abilities at a young age, Kevin exhibited psychopathic tendencies and was willing to hurt or kill anyone for his personal gain. This stemmed from being treated like a freak by his peers and family and was only exacerbated by the negative mental side effects he experienced whenever he absorbed too much energy. This caused Kevin to live with many insecurities about himself; he would embrace his "freak" title while also being paranoid of other people using it against him. His paranoia would progress to the point of considering everyone to be his enemy because, as he put it, "Nobody's innocent! They just haven't had the chance to make fun of me yet!"Framed Kevin thus lived on the streets, committing various crimes and cruel acts of violence; one telling instance of which was attempting to ram a money train into another train carrying passengers, and simply parroting the phrase "no pain, no gain" at the thought of all the innocent lives that would be lost.
Kevin's outlook began to change when he met Kwarrel, a fellow prisoner in the Null Void Incarcecon. Becoming a mentor to him, Kwarrel helped improve Kevin's anger issues and ultimately sacrificed his life to protect him. Kwarrel would forever remain in Kevin's memory, and helped to positively influence his personality....Nor Iron Bars a Cage Kevin would later want to become a hero of sorts (which was later manipulated by the Rooters' leader Servantis to further his own goal).Weapon XI: Part 2
By Alien Force (and onward), Kevin had changed significantly. Despite having become a con artist and an arms broker, he was much more stable, having developed a mature yet snarky and lax personality, "as cool as they come". No longer so angry, he dropped his big rivalry with Ben (what was previously so important to him) and worked with him and Gwen to honor the dying words of Magister Labrid. Though Kevin was initially untrusting of them, he befriended Ben and fell in love with Gwen during the time they spent together, growing to become a core member of their team. He also developed a respect for Max, whose younger personality Kevin's is said to resemble.Verdona
While changed for the better, Kevin still often shows a lawless delinquent side. He cannot resist a good scheme to make money (often with Argit).Kevin's Big ScoreToo Hot to Handle He once insincerely agreed to marry Princess Looma purely to get his hands on a Tetramand Engine Block.Many Happy Returns Despite this side of Kevin, Ben and (especially) Gwen still greatly trust him, and offer him second chances with each break in loyalty. Kevin once told Ben that he is grateful to them for having offered him compassion and changing his life.
Kevin healthily channels his delinquency through a love of cars and automotive engineering. He is extremely protective of his car, always working to improve it,Charm School and becomes very upset whenever it gets damaged, which happens on a fairly regular basis when Ben is around.
Kevin is shown to be very good with animals, even without trying. At one point, a Blowfish became strongly attached to him.Deep After he saved Zed from being crushed, she chose to join Kevin, despite being well-trained and previously very loyal to Khyber.Showdown: Part 2
Kevin's morals have also improved since he joined Ben's team. Though he may do unethical things, his conscience is clear. He now shows disgust at those who take advantage of others and the innocent, such as when he yelled at Argit for abusing Andreas' trust, sucker-punched Argit moments later for not showing any remorse for Andreas having sacrificed their life, brawled Zed's previous owner Khyber while calling him a jerk for his harmful and cold treatment of her, and reprimanded Ra'ad for being selfish and abandoning others to save himself, just like he would do when he was younger. He even stopped himself from a great prospect of money after noticing the containment suit he was tasked with breaking open was highly sealed for a reason.
Despite having adopted a more positive outlook on life, Kevin still suffers from his old insecurities, which resurface the most when he is mutated. The third time he mutated, he was visibly disgusted with himself and fluctuated between bouts of uncontrollable aggression and depression that jeopardized his relationships, especially with Gwen. As Ultimate Kevin, his actions nearly completely shattered his relationships with Ben and Gwen. He also returned to calling himself the familiar "freak" and "monster", voicing jealous frustration against Ben for being a famous superhero while he remained mutated.
While he cares for the innocent, Kevin is still willing to kill, either from necessity or his loyalties, and has expressed he would kill any villains that went after his family or the Tennysons. For example, he was willing to let Ragnarok die to avenge his father and advised Ben to kill Victor Valadis in order to destroy the Microchip Queen inside him.
Kevin is also prone to making blunders, such as foolishly revealing where Sugilite had gone to Vilgax,The Secret of Chromastone describing Charmcaster as "hot" in front of Gwen and admitting to kissing her, almost getting Baz-l killed when he revealed to the Vreedle Brothers that they would not be getting paid,Don't Fear the Repo and accidentally inspiring Prisoner 775 to try to kill Colonel Rozum.Prisoner Number 775 is Missing

Originally, Kevin's powers were believed to be of alien heritage, but later explained to be of a unique genetic component.
===Energy Absorption===
Kevin can absorb the energy of anything. This includes mana, as he demonstrated in his Ultimate Kevin form on Gwen.Absolute Power: Part 1
Kevin can absorb the energy stored in other individuals. This was shown when he, in his Ultimate Kevin form, absorbed Ra'ad, Bivalvan, Galapagus, P'andor and Andreas, all of whom had been turned into energy,Ultimate Aggregor from Ultimate Aggregor.
Kevin can also absorb energy by accident, as was the case when he collided heads with Servantis and absorbed the memories stored within the Loyalty Neuro-Matrix as energy. Kevin was able to carry the energy around on his hand and use it on Argit and Alan to restore their memories of their involvement with the Rooters.
Kevin can discharge his stored energy by projecting it out of his hands.
Kevin can infuse machines with his stored energy to activate them, as he demonstrated on an arcade machine, a forklift and a train conductor switch, or overload them, as he demonstrated on a keypad.
Using his energy absorption powers, Kevin can absorb DNA, either directly, remotely,Absolute Power: Part 2 or through devices such as the Omnitrix. By absorbing DNA, he also gains the individuals' powers and undergoes mutation to accommodate the absorbed abilities. His powers read DNA and clone it.
Kevin can also absorb DNA by accident, as shown when exposure to feedback from the original Omnitrix granted him the ability to transform into the aliens unlocked in the active playlist at the time, at the cost of only being able to stay human for a short time.
Kevin can use his body as a conduit for DNA, transferring it from a source to a target, as shown when Servantis used him to infuse the Rooters and Amalgam Kids with alien DNA, with the help of his technology.
By absorbing their energy, Kevin can also drain an individual of their life force, as demonstrated by Aggregor.Escape From Aggregor

Kevin can absorb the matter of anything, with some exceptions (such as the Techadon Factory)Greetings From Techadon from any part of his body. He can even absorb multiple materials at once.Plumbers' Helpers Depending on the amount of the absorbed material he has available, and how he distributes it, he can either coat his body, or part of it, in the material as armor, or completely convert his body, or part of it, into a living version of the material. Initially, he was supposed to create an outer shell with a small amount of material - he could use a quarter to coat a forearm arm with metal, but not his whole body. Then, once he began to form weapons and tools with the material, it became more of a transformation into the substance. His strength and durability in proportion to the material absorbed, though he can still feel pain.
Kevin can absorb the materialistic properties of living beings such as To'kustars, Petrosapiens, Crystalsapiens, Rock Monsters, and Evolved Vaxasaurians.

Kevin is capable of regenerating and regrowing any damaged or destroyed body parts, allowing him to grow back lost limbs.
Kevin has the power to increase his own body size and mass.The Ultimate Enemy: Part 2
Kevin can extend and enlargeThe Beginning of the End his arms.
Kevin can manipulate matter to fill in cracks or holes by releasing a liquid version of whatever material he has absorbed, as shown when he repaired the rock ceiling of a mine. He can also partially merge with the actual matter and manipulate the substance's form, as shown when he fused the seal of P'andor's suit, morphed it around P'andor, and fused the arms together as makeshift handcuffs.
Kevin has the ability to spontaneously create more of a given material by absorbing it. This allows him to create an endless supply, as shown when he was forced to mine Hedorium.From Hedorium to Eternity By generating matter, Kevin can also create objects, as shown when he created a helmet to protect Sir George from Dagon's mind control.The Ultimate Enemy: Part 1
Kevin can transfer the matter he has absorbed to another individual, as shown when he transferred his metal coating to Gwen to release her from Dagon's mind control. 
Kevin can also encase others in matter without shedding his own coating, as he demonstrated when he coated a truck driver in asphalt. He can also cover others partially instead of completely. He once used the metal he absorbed to fashion a helmet for Gwen to prevent the Lucubra from controlling her.The Creature From Beyond
====Rubber Form====
Kevin's body becomes highly elastic when absorbing rubber. He is able to bounce wall from wall, making his movements highly unpredictable, especially in a close quarter fight.X = Ben + 2
When his rubber coating is burned, a strong stench capable of incapacitating Incurseans is produced.
====Varsidium Form====
When struck, Kevin can amplify sonic vibrations. This was shown when Gwen hit him with mana to amplify Echo Echo's sonic screams, incapacitating the DNAliens in the process.Undercover
====Carbon Rod Form====
Kevin is provided with immunity to radiation. Furthermore, he is able to regulate the radiation produced by beings such as P'andor, by absorbing excess neutrons.

Kevin is resistant to cold temperatures, such as those on Mikd'lty.Map of Infinity
====Iron Form====
Kevin is immune to the Lucubra's mind control.
====Concrete Form====
Kevin is resistant to strong winds.
===Mutations===
Kevin has undergone several mutations as a result of absorbing or being exposed to feedback from the original Omnitrix, Ultimatrix or new Omnitrix, or absorbing alien DNA, namely:
*Pyronite Kevin
*Tetramand Kevin
*Kevin's Framed Mutation
*Kevin 11
*Kevin's Omniverse Flashback Mutation
*Kevin's Elemental Form
*Ultimate Kevin
*Kevin's Omniverse Mutation 
===Other Skills and Abilities===
Even without using his matter absorption powers, Kevin is stronger than an average human. For example, he was able to slow down a Pallorfang by holding its mouth open by its teeth.
Kevin is durable enough to resist impacts and blunt force trauma that would severely injure an ordinary person with moderate discomfort. For example, he can survive being thrown through a metal wall from afar.
Kevin can jump high in the air.
Kevin is highly acrobatic, as shown when he executed a forward handspring to grab a piece of debris.
Kevin has enhanced reflexes, allowing him to evade attacks quickly.
Kevin is a fairly proficient fighter. He doesn't employ a specific martial art in combat, but rather a loose street fighting style, focusing heavily on offense. He occasionally uses objects from his surroundings to aid him in battle, either in close or ranged combat.The Flame Keepers' Circle
Kevin has shown himself to be quite proficient in using weaponry, such as a Chilling GunThe Eggman Cometh and a Plumber blaster.
Kevin is proficient at driving, being able to drift and pivot in a vehicle as unorthodox as a three-wheeled buggy, even on sloped and unstable terrain.The Frogs of War: Part 2 He is also skilled at drag racing.Paradox
Kevin has impressive piloting skills, as shown when he pulled off a maneuver to escape a black hole in a Tachyon 930. He is considered to be a better pilot than Ben.
Kevin is excellent at mechanics and engineering. He makes frequent repairs and enhancements to his car and the Rustbucket 3, outfitting them with various pieces of alien technology. For example, with Rook's help, he was able to make his new car impervious to everything except magic. On top of that, he built the Mark 10, a car that he reluctantly gave to Ben as his 16th birthday present. He also made alterations to Ben, Gwen and his own Plumber suits to give them a combative edge while underwater by installing a propulsion unit and neuroshock pulsers, and was able to modify and completely rework a Plumber blaster in a very short amount of time.
Kevin possesses a vast scientific and technological knowledge of alien paraphernalia, being able to identify different pieces of technology at first glance, as he demonstrated on the components of the Proto-TRUK.
Kevin has great analytical and deductive skills, having been able to determine and find out specifically what happened in a battle between Aggregor and the Plumbers several hours after the battle, greatly impressing Ben and Gwen, and even gaining a compliment from Max that he could either be an expert police officer or a wanted criminal.
Kevin is very smart, but his formal education has been erratic, if not entirely lacking.It's Not Easy Being Gwen He knows a lot about some subjects, and absolutely nothing about others. Kevin's strongest intelligence is his street smarts: he is very wise and knowledgeable in the ways of the world, both on Earth and in other parts of the galaxy. He is also familiar with galactic court procedure on Coda Coda; and can at least read one alien language.
===Equipment===
Kevin owns a Plumber Snake, which Ben used to travel to the Null Void while tethering himself to Earth. However, it was damaged when Ben traveled too far away from the portal.Voided
Kevin owned a green and black muscle car, which was damaged in Upgrade's battle with Otto. He has since used parts from it to build a new car.
Lu lent the team his shuttle to allow them to return from the Moon to Earth,Birds of a Feather which Kevin stored in his garage. It is unknown if the shuttle was ever returned to Lu.
Kevin owns a Retrieval Beacon Generator.Singlehanded
During the team's mission to deliver the Prince of Lewoda to Jarett, they were given a Tachyon 930 by Zaw-Veenull. It is unknown if the ship was returned.
Kevin has a Plumber suit, allowing him to survive in unsuitable environments. He modified it by installing a propulsion unit and neuroshock pulsers.
Kevin owns a Chilling Gun.
Kevin was given a Taydenite car by Gar Red Wind. He chips little pieces of it for when he needs some money.
While working for the Rooters, Kevin wielded a blaster.
Kevin owned a Plumber Badge, which formerly belonged to Magister Labrid.Ben 10 Returns: Part 2 His badge has since been reassigned to Molly Gunther.
Kevin formerly kept a Universal Translator in the trunk of his original car, which the team gave to the Dragon to help them understand him and vice versa.Be-Knighted
Kevin formerly wielded a DNA Repair Gun, which he used to revert the DNAliens back to human. Simian later sold it to the Incurseans.
Kevin built a machine capable of hacking the original OmnitrixVengeance of Vilgax: Part 1 and Ultimatrix. It was destroyed after an explosion in his garage.
While stuck in his third mutation, Kevin used an ID Mask to look like his human form.The Final Battle: Part 2 He lost the ID Mask when Ben disguised it as the Ultimatrix symbol and placed it onto Vulkanus' back so that the Techadon Robots would attack him instead of Ben.
Gwen once lent Kevin a protection charm. It can protect the user only if they correctly recite the incantation on it, as Gwen stated that she would never see Kevin again if he mispronounced the incantation. It was last seen when Kevin dropped it on the ground, so it is unknown if Gwen ever got it back. 
Kevin temporarily wielded a Plumber blaster during the war between the Esoterica and Forever Knights, which he later modified.

Any energy, DNA or powers Kevin absorbs will dissipate over time or through excessive use, so he is required to recharge. However, for unknown reasons, when Kevin absorbed energy from Servantis' Loyalty Neuro-Matrix, he was able to store it for a long time.
Whenever Kevin absorbs the DNA of other lifeforms, he only gains 1/10th of their abilities.
Absorbing energy, DNA or powers causes Kevin to become insane. An exception to this is when he absorbed DNA from the new Omnitrix, as he was able to retain his sanity in his mutated form (albeit faking insanity to Ben) due to having absorbed energy from Servantis' Loyalty Neuro-Matrix. Being drained of the energy, DNA or powers he has absorbed will restore his sanity, at the cost of making him exhausted. 
Depending on his self-control, emotional and mental state and how much energy/DNA/power was absorbed, Kevin may not be able to permanently revert from his amalgamated mutations. Initially, he could not permanently revert from his Kevin 11 mutation, but eventually did so with Kwarrel's help, and was later able to use what he had learned to revert from his Omniverse flashback and present-day mutations. However, he could not revert from his Ultimate Kevin mutation as, compared to the other three mutations, he had absorbed more DNA samples and, as a result, had become more insane.
Initially, Kevin could not absorb enough matter from small objects to completely coat himself, and needed a sample approximate to him in size.Darkstar Rising However, he no longer has this problem as of Omniverse, and can coat his entire body with just small shard of material.
Kevin is unable to use his matter absorption powers while wearing a spacesuit or Plumber suit, giving him a major disadvantage in combat.
In his metal form, Kevin is vulnerable to electricity.
In his metal form, Kevin can be magnetized. However, he can use this to his advantage, as shown when Lodestar launched him at the Mech Dragon on one occasion and Zombozo on another.The More Things Change: Part 1
In his wood form, Kevin is vulnerable to fire.
Kevin can be forced to absorb matter by coming into contact with an Absorption Band.
Most of Kevin's powers can be neutralized by Energy CuffsBen 10 Returns: Part 1 or a power dampening headband.Viktor: The Spoils
Kevin can be immobilized by ice, as shown when he was frozen by the DNAlien Freeze Guns.
Kevin can be rendered unconscious by sedative quills, such as those generated from Argit's species.
Kevin is vulnerable to snake venom.
Kevin is afraid of alligators.

====Ben Tennyson====
See Article: Relationship with Ben Tennyson
====Rook Blonko====
Rook and Kevin share an interest in automobiles. They have visited auto shows together and worked on Kevin's new car.
After Kevin witnessed the Proto-TRUK in action and examined it, he told Ben that Rook is the coolest guy Ben has met who isn't Kevin himself.
Kevin and Rook also tend to engage in playful banter.
Although they get along for the most part, Kevin has expressed annoyance at Rook's politeness and adherence to Plumber protocol.
===Love Interests===
====Gwen Tennyson====
See Article: Relationship with Gwen Tennyson
====Charmcaster====
In In Charm's Way, Charmcaster used a spell that transformed her into a blonde teenage girl named Caroline as part of her plan to charm and hypnotize Kevin. She and Kevin journeyed to the beach where she revealed a partially false life story while removing the ID Mask that concealed Kevin's mutant form, clearly growing jealous of Gwen when Kevin mentioned "You think you can do magic? She's made of magic". She then kissed him, putting him under her hypnotic influence through a spell, and then ordered him to bring Gwen to the planetarium before midnight where she could drain Gwen's magical and Anodite powers. To fortify or deepen her hypnotic control over Kevin, she also granted him a magic amulet. Kevin was broken free from Charmcaster's influence spell after the amulet was broken by Ben.
Kevin thinks Charmcaster is hot and was attracted to her while in disguise. However, she never liked him and was just taunting him.
After this incident, Kevin and Charmcaster were mostly enemies, with Kevin disliking Charmcaster until he learned just how similar they are. He initially attempted to brush this empathy off, but when Gwen trapped Charmcaster in her own bag and kept her under the goal of becoming friends with her, Kevin seemed relieved, knowing firsthand how Gwen can help change a person.
===Neutral===
====Jennifer Nocturne====
Jennifer Nocturne is a 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 Jennifer was kidnapped and saved by Kevin and Gwen, Nocturne asked Kevin out. When Gwen heard this, she became jealous of her and said angrily "I will peel you like a grape!".Hero Time

====Punch Time Explosion XL====

==Online Games==
=== The Alien Device ===
Kevin is the first and penultimate villain in The Alien Device that Ben sends back to the Null Void with the Null Void Projector.
==Etymology==
Kevin's last name is derived from "Eleven" while also having the spelling altered so that his first and last name are eye rhymes as well as phonetic rhymes. This lines up with his age in the Original Series and is similar to Ben's first and last names which, when shortened, also contains a number that rhymes with his first name.
==Trivia==
*Kevin is the first villain from the Original Series to return in Alien Force.
*Kevin had a few girlfriends prior to Alien Force.
*Kevin watched Captain Planet and The X-Files when he was younger.The Widening Gyre
*A running gag in the series is Kevin becoming distraught every time his car or the Rustbucket 3 get damaged or destroyed.
*Kevin's mother used to read The Princess Bride to Kevin when he was younger.
*When Kevin was in the Null Void, he had an alien pet that he called a dog. The pet once got sick and Kevin had to take him to a vet named P'strph, who made Kevin put a cone around his neck.All That Glitters
*In Alien Force and Ultimate Alien, Kevin lived in an apartment in Bellwood. He sometimes slept at his mother's house, which he bought for her, and his main garage was there. In Omniverse, Kevin initially lived in a garage in the same area as Friedkin University, later revealed to be Paik's Body Shop. Sometime prior to Charm School, he moved into the Friedkin University basement and currently lives there.
*Kevin and Gwen are famous on Earth, just not nearly as famous as Ben. Dwayne McDuffie compared their level of fame to that of American television personality Gayle King. 
**However, Kevin is still very famous in space.
* The Alien Force crew knew how Kevin escaped the Null Void, but the story was never revealed in an episode.
**However, a hint was given in Plumbers' Helpers after Ben as Swampfire escaped the Null Void.
*When asked if Kevin would get a haircut in Ultimate Alien, Dwayne stated that he was hiding something by keeping his hair long. Correlating with this, he also stated that Osmosians do not generally groom or cut their hair. However, as Osmosians have been retconned in Omniverse to be a subspecies of humans, it may now be a moot point.
*Kevin got the small, grey padlock that he wears for a necklace from his first crime, which was stealing a bike to run away from Bellwood.
*Kevin was the first non-family member that Ben shared his secret with.
*Kevin's real father was abusive to him.
**Derrick J. Wyatt speculated that Kevin remembered his actual father after defeating the Rooters.
*Kevin was created by Joe Casey, inspired by the The Seven Million Dollar Man episode of The Six Million Dollar Man. Originally, he was to have an Omnitrix of his own. While this concept ultimately did not come to pass, it was eventually brought back in the reboot.
**Joe Casey prefers his original idea to the change to Kevin's powers made in Alien Force.
*Kevin's Original Series design was made by Dave Johnson.
*Kevin's Alien Force and Ultimate Alien design was initially created by Glen Murakami. His face was tweaked and his body was slimmed down by Glenn Wong, with colors added by Chris Hooten. 
**Kevin's grey trunks in What Are Little Girls Made Of? and his winter coat in Escape From Aggregor were designed by T.J. Collins. The former was the first character design he ever got approved.
*Kevin's Omniverse design was created by Derrick.
*Kevin wears wholesters in Omniverse because his voice actor, Greg Cipes, wears them too.
*The idea of Kevin adopting Zed was requested by Greg Cipes due to his love of animals. Early on, there were some thoughts of an Earth dog for Kevin, which Derrick started designing, before the crew decided to give him Zed.
*It was Derrick's idea to give Kevin his scar in Omniverse.
*An alternate counterpart of Kevin does not exist in Rex's home universe. This was proven true during Ben's visit there, as he hypothesized that Kevin may not exist on Rex's Earth.Ben 10/Generator Rex: Heroes United
**Little to nothing is known of Dimension 23's Kevin, other than the fact that he works as a busboy in Mr. Gyro.
** Kevin's counterpart in Nega Ben's timeline is pretty jockish, has bleach blonde hair, and is well-tanned. He is also dating Gwen. 
**Kevin's counterpart in Benzarro's reality is missing.
**It is unknown if a counterpart of Kevin exists in Mad Ben's dimension.
**Kevin's counterpart in the Gweniverse has not met Gwen 10 yet.
*In Derrick's opinion, there is no universe where Kevin wields the Omnitrix.
