Two brothers of the SCP foundation. SCP 073: Cain, pacifist and kills all plant life with a 30-60 mile radius. Cain can't die, and any injury he receives, reflects back onto the attacker. SCP 076-2: Abel, a bloodthirsty brute who goes on a rampage when he leaves his coffin. He wants to kill Cain. He does calm down after a while.
