Jesse has the ability to use sound as a weapon. His voice can knock people unconscious and cause physical damage. He is a villain from Level 5 and early in Season 3, he participates in a bank heist with Knox (The Fear Manipulatior), The German (The Magnetic Man) and Flint (The Fire Manipulator). His body is initially shared with the present-time version of Peter Petrelli, who was placed in Jesse's body by the Peter Petrelli from 4 years in the future. It is unknown how the future version of Peter is able to do this, but he removes present-day Peter from Jesse's body in the middle of Episode 3, One of Us, One of Them, returning it to Jesse's control. He is later killed by Sylar.
