He is voiced by Jullian Holloway in a Cockney accent.
He first appears in "Over The Top." In this episode, Death and Skips arm-wrestled for Rigby's soul (who had died earlier in the episode). After Death lost, he swears that he will have his revenge, brings Rigby back to life, and disappears.
He returns in "Skips Strikes" and competes against the Park Strikers, a bowling team consisting of Rigby, Skips, Mordecai, and Benson. He blackmailed Skips that if he competes, Death will tell his secret to everyone. At the game, he and his teammates cheated by using their magical powers to make strikes. After losing thanks to Skips, he gives Rigby a soul ball and then he and his teammates left.
He returns in "Dead at Eight", along with his wife and their child, Thomas. After his babysitter canceled, he shows up to take Muscle Man's soul, due to his stunt. He gives Mordecai and Rigby a proposition; if they successfully babysit Thomas and put him to bed before eight, he would spare Muscle Man's life, otherwise, he would put him in his wife's jewelry box. After he came home, he sees the place trashed, but his wife was pleased that Thomas was asleep (knocked out). He tells Mordecai and Rigby that they were the best babysitters ever and frees Muscle Man. In the end, he predicts that Muscle Man will die in a hot dog eating contest.
He appeared in "Exit 9B" to help Mordecai and Rigby.
In "Last Meal", he appears about his prediction of Muscle Man's death coming true; by a hot dog eating contest. When everyone tried to bail Muscle Man out of the competition, Death decides to take Muscle Man's soul anyway. So, Death decided to challenge Muscle Man for his soul. Later, when he notices Muscle Man and Starla making out in public, Death throws up, making him disqualified. He leaves angry and spares everyone.
He wears a black jacket and appears to be pretty strong in his right arm, but weak in the other; also, he has long brown hair and appears to be a skeleton.
