Thanatos
From the Soulcalibur Wiki
A giant scythe wielded by Death. Thanatos is the personification of death in Greek mythology. This soul-harvesting weapon could indeed be described as death incarnate. It was originally designed to be used by the angel of death, who had no reason to fear injury, and thus is not constructed to provide any defense.
In-game, it restores health with every successful strike. Offense: 100% Defense: 140%
