This is the mutation 17-year-old Kevin underwent in Weapon XI: Part 2.


17-year-old Mutant Kevin's face resembles Shocksquatch's, but had red eyes, Kevin's hair, Whampire's mouth, a crest belonging to both Shocksquatch and Ball Weevil, and Feedback's antennae.

His upper right arm belongs to Bloxx, his upper left arm belongs to Gravattack, his lower right arm belongs to Astrodactyl, and his lower left arm resembles The Worst's but with claws resembling Wildmutt's.

His torso mostly resembles Shocksquatch's, with pieces of both Bloxx and Gravattack near the shoulders. He has a set of wings on his back, with a left wing belonging to Pesky Dust and a right wing belonging to Astrodactyl. He wears pants resembling Kevin's Rooter uniform, and has Crashhopper's legs.


During Weapon XI: Part 2, Kevin touched the Omnitrix symbol on Gutrot to turn into this most recent mutation. Kevin then battled Swampfire before Ben exploited a weakness in this mutation by kicking Kevin's legs and knocking him down. However, Ben was caught by Helen and they brought Ben to Servantis, who built a device that was going to be used to destroy Ben and the Omnitrix at the same time.

Before he could put Ben inside, Kevin dropped Ben and then grabs and headbutts Servantis, destroying his loyalty neuro-matrix and locks out Servantis from the Amalgam Kids' minds forever. Kevin uses Feedback's abilities to give back the memories to the Amalgam Kids and reveals to Ben that he did that to get in close with Servantis before returning to normal.

Powers and Abilities

Kevin is shown to be having better control over this mutation than others, as he intentionally betrayed Servantis, freed the Amalgam Kids from his mind control, and reverted back to his conventional form.

Mutant Kevin has access to Gravattack's gravikinesis, Ball Weevil's plasma balls, Astrodactyl's energy whips, and Shocksquatch's electrokinesis during his fight with Swampfire.

When he betrayed Servantis, he utilized Feedback's elastic antennae and energy absorption/redirection powers in severing his control over Alan, Helen, and Manny.

He also possesses Crashhopper's enhanced jumping and Bloxx's enhanced strength.


Because he had Crashhopper's legs, hitting Mutant Kevin's legs correctly will make him move backwards. 


Ben 10: Omniverse

Season 6


  • This is the only mutation to use aliens unlocked in a previous series, as Shocksquatch was introduced during Ultimate Alien and Wildmutt first appeared in the original series.
    • Ultimate Kevin does not count, as any previous aliens got locked then reunlocked.
  • Mutant Kevin's gravitational aura, plasma balls, energy whips, and electric blasts are all colored red, whereas these abilities are usually colored green when used by the aliens this form is made from.
