Resurrection Man
Mitchell "Mitch" Shelley was a simple Southern lawyer until he was injected with nanotechnology called tektites that killed him. And then brought him back to life without his memories. Mitch wandered for months, trying to remember his past life. Along the way, he discovered that every time he's killed, the tektites in his body resurrect him, giving him a different super power each time. Eventually regaining his memories and feuding with fellow immortal Vandal Savage, the Resurrection Man now tries to leave a simple life and fight the occasional odd menace.
