Kevin Levin is a prominent character in the Ben 10 franchise. When Kevin first appeared in the original series, he quickly became one of Ben's most notable enemies. However, he reformed in Alien Force, and became one of the main heroes. In the reboot, Kevin is one of the main antagonists in Season 3.
