Eric Williams was born in Paterson, New Jersey and Simon Williams's brother. Eric was the black sheep of his family. His mother Martha would tell him that he was 'born bad', while heaping affection on Simon. Eric's father was charged with disciplining him, but was abusive and uncaring. His father even preferred to watch TV lazily, while Eric was torturing the family cat. At the same time, their mother was loving and attentive to Simon, making Eric bitter and jealous. One day Eric was playing with chemicals in the garage, and caused a fire which burned down their house. Simon felt guilty for not stopping Eric, and resolved to be responsible for Eric from there on. As they grew older, Simon grew studious while Eric was an athlete. Eric also became more rebellious, and tried to get Simon to join in his petty thefts. Eric eventually became a gambler, joined the Maggia and moved to Las Vegas, while Simon took over the family business Williams Innovations. When Williams Innovations began to fail partly due to competition with Stark Industries, the desperate Simon turned to Eric's mob ties for help. Simon embezzled money from the company to invest with Eric, but Simon was caught and jailed. Simon was freed from jail by Baron Heinrich Zemo, induced by an offer of revenge on Iron Man and the Avengers to which Eric's brother was transformed into Wonder Man. Learning of his brother's death, Eric was inflamed with guilt and anger. Through his Maggia contacts, he contacted the Tinkerer to provide him with his scythe weapon, which was further enhanced by Ultron with coma-inducing abilities. Taking the "Grim Reaper" name, he became a professional criminal and defeated Hawkeye, Goliath and the Wasp, placing the three Avengers in comas, but was beaten by the Black Panther's surprise appearance.
