|Series||Ben 10: Ultimate Alien|
|Voiced by||Greg Cipes|
Kevin Ethan Levin is a former nemesis of Ben Tennyson and one of the main three characters of Ben 10: Alien Force. He can absorb the properties of any surface and use them to fight with, which later states him as a hybrid-osmothian. Previously, he was one of Ben's most hated rivals as he tried to absorb the power of Ben's Omnitrix. He succeeded, only to result in his human form permanently mutated into a freakish combination of all 10 of Ben's aliens. He returned in Ben 10: Alien Force after being left in the Null Void for the rest of Ben 10. His DNA had later stabalized and he returned to his human self. He is now Ben and Gwen Tennyson's ally as they fight the DNAliens and enemies new and old.
Backfiring PlanEditTired of guerilla tactics, Kevin decided it was time he took the war directly to Fuse's lair. With the help of the Hero, he was able to collect some samples of the local Fusion Spawns, and absorbed their Fusion Matter, hoping to match Fuse's strength.
Unfortunately, Kevin's plan backfired, and Fuse gained control over him through the absorbed Fusion Matter. Under Fuse's control, Kevin tricked the Hero into attaching a device to Foster's Home in order to transfer Imaginary Energy to Fuse's lair in the Darklands for study. Fortunately, Dexterwas able to uncover the plot, and was able to slow down the transfer, and free Kevin from Fuse's control. Dexter was unable to completely stop the transfer however, because doing so would prove fatal towards the Imaginary Friends. However, it seems to have weakened after Billy got into the lair of Fusion Kevin in Green Maw. Fuse continues to use Kevin by using car keys stolen from him to produce an army of Fusion counterparts that resemble 11 year old Kevin's giant alien form in Fuse's Lair.
