Kevin Levin, or simply, Kevin, is a teenager that Ben meets after
having an argument with his Grandpa Max. Unlike other normal beings, he
has the unique ability to absorb any type of energy. He can then use
the energy obtained at his own will. When Kevin attempts to absorb the
Omnitrix's aliens, he becomes an incomplete, but very effective,
version of that alien. At the end, he is defeated after the Omnitrix
unexpectedly released a feedback pulse, though he seems to have
acquired Heatblast's powers permanently, maybe others as well.
