Powers and Abilities
When Brother Eye chooses so, Kevin is transformed into the O.M.A.C. His abilities in this form include enhanced strength and fighting abilities as well as the ability to tap into electromagnetic devices, such as computers. Kevin is mostly powerless when he is under the control of Brother Eye. When in his regular form, he can communicate with Brother Eye through most electronics devices, including televisions, cell phones and personal music players. As a section leader at Cadmus, it can also be assumed that he is relatively skilled in the field of biology and specifically genetics.
Following the destruction of Brother Eye, Kevin gained control over his O.M.A.C. form, but also found himself trapped in this body, unable to revert back to his human state.
