High Quality Content by WIKIPEDIA articles! Nathan Petrelli, portrayed by Adrian Pasdar, is a fictional character on the NBC science fiction drama series Heroes. He is a New York lawyer-turned-senator with the power of self-propelled flight. Ambitious and pragmatic, Nathan has a decidedly anti-hero streak, which exacerbates his complex relationship with his brother, Peter Petrelli. Nathan was the main villain at the beginning of Volume 4: Fugitives, but, after being exposed as an evolved human by Danko, redeemed himself. After being killed in battle by Sylar, a copy of Nathan`s mind was created to control Sylar`s body so he still lived in some form, but he eventually lost control to Sylar and was then dead for good.
