Powers and abilities[edit | edit source]
In the Prime Timeline, Kevin is an Osmosian capable of absorbing energy, matter, and DNA. His powers were believed to be either an unexplained mutation or alien heritage, but this later explained to be of a unique genetic component.
Kevin has the ability to absorb the energy and matter of anything (excluding certain materials) through his body at will and utilize it in various ways. If he is not absorbing excessive amounts of matter or biology directly into his body, he becomes wrapped in a coating that leaves his clothes intact. However, if he is wearing a Plumber Suit, the suit will not remain intact.
Kevin as undergone multiple mutations, most of which involved using his powers on the Omnitrix. Each Omnitrix-related mutation results in Kevin temporarily gaining the natural abilities of each species present.
In an alternate timeline, Kevin is an ordinary human equipped with a replica of the Omnitrix called the Antitrix that he generally uses to fight Ben out of pride and jealousy. Similar to the Prime Timeline Kevin's mutations, the Antitrix aliens are "cross-contaminated" hybrids.
Weaknesses[edit | edit source]
While Kevin can absorb all sorts of compatible matter, he cannot take too much of it. Such as with the Omnitrix, where he became mentally unstable and lost all accounts of control from all the DNA given to him. However, Kevin has recently overcome this weakness by mastering his powers.
12-year-old Mutant Kevin can be incapacitated by quills fired by Argit's Species.
Ultimate Kevin was sensitive to high-pitched noises, such as those produced by an Evolved Sonorosian.
Personality[edit | edit source]
When Kevin first appeared, he quickly became one of Ben Tennyson's most notable enemies, through he reformed by age 16.

Notes[edit | edit source]
- In the original continuity, Kevin's padlock was a spoil from the first crime he committed as a child, which was stealing a bike and using it to run away from Bellwood to New York.
- In the reboot cotinuity, the padlock contained a tracker that was placed there by the Forever Knight before Kevin destroyed it in the episode "Franken-Fight".
- The idea of Kevin having his own Omnitrix in the reboot was a repurposing of an unused concept intended for the original series.
- The creators of the original series intended for Kevin to be a mutant.
- Kevin was the first non-Tennyson family member that Ben shared his secret (i.e. the Omnitrix) with.
- Kevin got this X-shaped scar due to being whipped by Swampfire. His counterpart in Ben 10,000's timeline also has a scar of the same shape.
- As the Antitrix aliens have been confirmed to be "cross-contaminated" hybrids, Monster Kevin is technically comprised of 23 different species, including human, Tetramand, Pyronite, Kinecerlan, Subsapien, Arburian Pelarota, Galvanic Mechamorph, Galvan, Cascan, Florauna, Lepidopterran, and Bashmouth's Species.
- Due to some of Monster Kevin's body parts having a more purplish coloration, Bootleg's arm more closely resembles Upgrade's.
- Monster Kevin is inspired by both Kevin 11 and 12-year-old Mutant Kevin from the original continuity.
- The reboot version of Kevin shares many similarities with Albedo from the original continuity.
