First Appearance Kevin 11


In, Ben 10: Omniverse, Kevin wears the same shirt but the sleeves and collar are cut in bumpy ways, his gray shirt is slightly torn and he wears gray straps with pockets. His hair is longer and straighter and there is a small tear below his left knee. He also wears a padlock necklace similar he wore when he was eleven but marked with the number '11'. Later in the series, Kevin grows a small beard and his grey shirt gains stripes.


Ben 10: Omniverse


  • According to Derrick, the creators of the original series intend for Kevin to be a mutant not an alien hybrid.
  • In Omniverse, Kevin will live in the same area as Gwen's college rather than Bellwood.
