Stamina: Superhuman

Range: Planetary

Standard Equipment: The Enchiridion when possessing Billy. Otherwise none.

Intelligence: Gifted. The Lich is a diabolically cunning being whose knowledge and experience seems to be shared among every Lich from alternate timelines, in which there are infinite. The Lich employs a selection of powerful magical spells and abilities into combat, most of which seem to be based around affecting the target's mind. The Lich has the ability to possess others and has the intellect to act just like the individual they're possessing, as seen in how similar his personality was to Billy's when he possessed his body.

Weaknesses: As a being of death, The Lich is deathly weak to life-based powers. This can be seen in the episode Escape from the Citadel in which a small dab of the Citadel's "healing water" completely incapacitated The Lich, causing him to devolve into a being of love (Sweet P). The Lich is a being whose primary function is to bring death and destruction, and when he is unable to kill anything, he becomes paralyzed
