This section is for the Non-Player Characters that that appear in The Sims series, ordered by the game that said NPC first appears.
The Grim Reaper
- Debut: The Sims: Livin' Large
Appears in: The Sims: Livin' Large, The Sims 2, The Sims 3, The Sims 4, The Sims Medieval
- Chess with Death: In most games, a living Sim can challenge him to a contest for the chance of saving whoever he's currently reaping.
- In the first game, he goes with Rock–Paper–Scissors, though only if he's in a good mood. Beating him means he lets the dying Sim live, while losing might lead to either him finishing the reaping, or he may raise the Sim as a zombie.
- In the second game, he plays a "Which hand is it in?" game, the 'it' being the dying Sim's soul. Notably, this is not a 50/50 game as it may seem, as the pleaing Sim's chance is based on their relationship with the person they're trying to save.
- The third game is the most literal, as he actually does play Chess in this iteration. His skill at chess is above average, but nowhere near unbeatable, so an experienced Chess player has a good chance of saving the recently departed.
- Curb-Stomp Battle / Did You Just Punch Out Cthulhu?: In The Sims 4, evil chickens (yes, chickens) from the Cottage Living expansion will straight up fight him to either save their owner or ward him off their property. They will always win the fight regardless...
- Did You Just Romance Cthulhu?: Grim is the proverbial Cthulhu in this case, as Olive Specter of Strangetown has a memory of Woohooing with him, with the implication that this is what lead to the birth of Nervous Subject.
- Don't Fear the Reaper: He is a fair bit nicer in The Sims 2 than the other entries, particularly if someone with high aspiration dies of old age, where he'll arrive wearing a lei, alongside a pair of hula dancers, and offer the Sim a drink before calmly guiding them to the afterlife.
- Everybody Hates Hades: In The Sims 4, if asked about his relationship status, he'll reply that "The forces of evil have no time for romance", painting him as a Card-Carrying Villain.
- Sadistic Choice: The end of Vincent's story in Life Stories has the Reaper offer one of these. He is willing to resurrect Naomi, who was just crushed by a falling satellite, but only if Vincent gives up his earthly belongings. The player gets to decide which choice Vincent makes.
The Therapist
- Debut: The Sims 2 (only appearance)
- No Name Given: Simply referred to as "Therapist" by the game.
Mrs. Crumplebottom
- Debut: The Sims 2: Nightlife (only appearance)
- Ambiguously Brown: She has tanned skin, which stands out since most other members of the Crumplebottom family are fair skinned.
- Ambiguously Related: How exactly she is related to the other Crumplebottoms is not known.
- Handbag of Hurt: Her reaction to public displays of affection.
- Hate Sink: Clearly not meant to be very likeable. She purely exists to be a local nuisance and she doesn't have a tragic backstory like her predecessor.
- Iconic Item: Her purse.
- Suspiciously Similar Substitute: Wears practically the same outfit Agnes did in Hot Date, and just like her, responds to public displays of affection by beating on the couples with her purse.
The Mother Plant
- Debut: The Sims 4: StrangerVille (only appearance)
This alien plant resides in an underground laboratory and is the main cause of StrangerVille's "strangeness" because she creates bizarre fruit and other objects that cause infections and possess local Sims. It's unknown how she even got there in the first place, so it's up to the player's imagination.
The story of this pack involves investigating the "strangeness" and either defeating her to stop the infections, or befriending The Mother, which is easier said than done since your "relationship" with her starts in the high negatives.
- Bizarre Alien Biology: She looks like a giant multicoloured tentacle with three smaller ones next to her. She also has a tongue that acts like a lasso so she can grab and swallow Sims whole in an instant.
- Bullying a Dragon: A single Sim can antagonize the Mother by taunting her or by attempting to fight her alone... you do the math on what happens next.
- Laser-Guided Karma: Once you manage to defeat The Mother, you can use her to control the infection around StrangerVille, or even disable it completely.
- Swallowed Whole:
- Expect this to happen to your sim if you antagonize her too much.
- Your played sim will also suffer this if you fail to defeat her in battle.
- To Serve Man: She can eat Sims by grabbing them with her tongue and swallowing them whole.
- Vile Villain, Saccharine Show: The first real villainous creature in the Sims series, with the goal of the pack being to find a vaccine to cure the infections caused by her and finally defeat her using the vaccine, failure to do the latter results in your sim being eaten by her and your friends possessed.
