Kevin Levin (ST10)

Appearance
Kevin appears to be a youthful, 15-year-old boy with shaggy, somewhat curly hair and black eyes. He has freckles scattered across his face. On his left wrist is the Antitrix, a device that grants him the ability to instantly change his appearance. However, it currently does not work.

Personality
Kevin is a seemingly sadistic 15-year-old boy whose troubled past led him to run away from home. In fear of being judged by others, Kevin is antagonistic towards most people. Beneath his hard-hearted exterior is a heart of gold, which he rarely shares with others.

Powers and Abilities
Kevin wielded the Antitrix, a device created to mimic the Omnitrix. With the ability to instantly transform the user into various alien forms, stronger than Ben's own aliens, the device proved to be worthy competition before it was disabled by Ben's own Omnitrix.

Kevin, as an Osmosian, can absorb DNA, energy, and matter at will. However, doing so in excess strains his mind.

Weaknesses
The Antitrix aliens were highly unstable when the device was active, and were hard to control and master, even for Kevin. Now that the device is disabled, Kevin must rely on his own abilities as an Osmosian.

As an Osmosian, use of his abilities can excessively tire him out or strain his mind, making him mentally unstable for a fair amount of time.

Biography
The events of Ben 10, Ben 10: Race Against Time, Ben 10: Destroy All Aliens, and some flashbacks seen in Ben 10: Omniverse are canon within this Kevin's timeline, with some alterations.

Between the Omniverse flashbacks and where Alien Force would take place, Kevin obtained the Antitrix and was tasked by Albedo to retrieve Ben's Omnitrix, but eventually, Kevin's Antitrix was disabled by a function in Ben's Omnitrix. Kevin moved to Bellwood soon afterward, and would come to occasionally help Ben with threats Ben alone can't handle.
