What is the name of the grim character that appears when a Sim dies?

The grim character that appears when a Sim dies is the Grim Reaper.

The Grim Reaper is a recurring non-player character in The Sims series who arrives at the scene of a Sim’s death. He interacts with the corpse and removes the deceased Sim from the household and game world, making him one of the series’ most recognizable supernatural figures.

The character became especially notable in The Sims: Livin’ Large, the first expansion pack, released in 2000. In that game, living Sims could plead with the Grim Reaper to spare their friend or family member. The outcome could involve a game of rock-paper-scissors: winning might revive the Sim, while losing could result in permanent death or transformation into a zombie.

“Death Angel,” “Dark Shadow,” and “Soul Collector” fit the general idea of death-themed characters, but they are not the canonical name used by The Sims. In later games, including The Sims 4, the Grim Reaper remains an active character and is even connected to expanded death, ghost, funeral, and afterlife gameplay.
