Devlin Levin

Devlin Levin is Kevin Levin's son and Kenny's best friend. When they first met, Devlin tricked Kenny into leading him to a Null Void Projector which he used to free his father.

Appearance
Devlin bears a striking resemblance to Kevin when he was his age. He is tall for his age, has long black hair pulled back in a straight ponytail and the sides of his head are shaved, he also has dark blue eyes and pale skin. He wears a dark gray short sleeved hoodie, a black long sleeved shirt, black pants, black and white shoes and a bandage around his right leg.

Powers and Abilities
Devlin can change from human form to Devlin 11 (a copy of Kevin's original mutation) at will and he gains all of the powers Kevin had in this form. However, he did not inherit Kevin's ability to absorb matter and energy (confirmed in pop-ups).

Trivia

 * According to Derrick J. Wyatt, Devlin was grounded with Zed during the events of The End of an Era.
 * Apart from having the same mutation as Kevin did at his age, Devlin shared many aspects with Kevin:
 * Devlin met Kenny in the same way Ben met Kevin, after Kenny went off after getting upset with Ben much like how Ben went off after getting upset with Max.
 * Unlike Kevin, Devlin liked his friendship with Kenny.
 * Furthermore, Devlin didn't have the sociopathic tendencies his father had at his age and, in the end, was approached with the same offer to join the team that Ben offered Kevin.
