Eric Williams, better known as the Grim Reaper, is a Marvel Comics supervillain. He is the elder brother of Simon Williams, Wonder Man.

Consumed by jealousy over Simon's successful life and fueled by resentment after Simon seemingly died (and was later resurrected), Eric blamed the Avengers for his misfortune. This resentment turned into a deep-seated hatred, leading him down a path of villainy.

The Grim Reaper's signature weapon is a scythe, initially a cybernetic attachment replacing his hand. This scythe can generate powerful concussive force and energy blasts, making him a formidable opponent in combat. He also has superhuman strength and durability.

Throughout his history, the Grim Reaper has repeatedly clashed with the Avengers, particularly his brother, Wonder Man. He has also formed alliances with other villains, seeking to destroy the heroes he believes wronged him and achieve his twisted vision of justice.
