Adam Monroe

Adam Monroe was an evolved human with the ability of rapid cell regeneration. His powers were so advanced that he was unable to age or die, making him near-immortal. He originally discovered this while living over 400 years ago in feudal Japan (as Takezo Kensei). Adam, with time, saw the world to be corrupt and in need of a massive cleansing of humanity. To aid him in his plans, Adam brought the Company's founders together, but in the end was betrayed, forcing Adam to rely upon himself to save the world. After the failure of his plans to "cleanse" the world, Adam was killed by Arthur Petrelli, who stole Adam's ability, rendering him mortal as he aged 400 years in a few seconds.
