Adam Monroe was one of the founders of The Company. But power corrupted him. Through the help of Hiro, Adam discovered his abilities while living in feudal Japan as Takezo Kensei.
Adam possesses the ability of rapid cell regeneration. Like Claire, he's sometimes unable to regenerate if an object is inside of his body until that object is removed. The cells in his body are dying then healing, effectively making Monroe immortal.
