A six-foot-tall dwarf raised by dwarfs in the mines of Copperhead who joined the Ankh-Morpork City Watch after his adoptive parents decided the city needed him more than they did. Carrot is almost certainly the rightful king of Ankh-Morpork, though he has never claimed the throne. He is genuinely good — not naive, not simple, but good in a way that makes people around him want to be better. He carries a plain iron sword that is nonetheless extraordinarily effective, has memorised the entire city laws, and is enormous, charming, and almost impossible to corrupt, which makes him either the best or most dangerous person in the Watch depending on your point of view.

A werewolf and one of the most capable officers in the Ankh-Morpork City Watch, who joined as a diversity hire but stayed because she is exceptionally good at the work. She can track by scent across the entire city. Her relationship with Carrot is complicated by her nature — she changes with the full moon and struggles with the duality of being both wolf and human, predator and police officer. She comes from an aristocratic Uberwald family and has complex feelings about what she is.

Sergeant Fred Colon has been in the Ankh-Morpork City Watch for most of his adult life, surviving by the simple expedient of never going anywhere dangerous. He is comfortable, unhurried, and holds views about policing that predate most of the city's reforms. Together with Corporal Nobby Nobbs, he forms the Watch's least effective (and somehow most durable) partnership. Colon is not malicious, just limited — a decent man whose decency has never really been tested by anything more serious than paperwork.

Corporal Nobby Nobbs carries a signed certificate from the Patrician confirming that he is, probably, human. This is a more unusual document than it sounds. He is small, grimy, light-fingered, and has a face that has been described as one that not even a mother could love (his mother agreed). Despite appearances, Nobby has survived his career in the Watch longer than almost anyone, which says something about either his luck or the city's general standards. He is partnered with Sergeant Colon.

A troll member of the Ankh-Morpork City Watch, now a Sergeant. Trolls are silicon-based life forms who think more clearly in cold temperatures — Detritus wears a refrigeration helmet that has made him considerably more intelligent than his colleagues initially assumed. He carries a converted siege crossbow called the Piecemaker, which fires an entire bundle of bolts simultaneously and should not be used near anything you want to remain standing. He has a wife, Beryl, and takes his duties extremely seriously.

A dwarf forensic alchemist in the Ankh-Morpork City Watch, and one of the first Discworld dwarfs to publicly present as female — a revolutionary act in a culture that does not officially acknowledge female dwarfs. Cheery wears a small amount of makeup and occasionally a skirt (over her chainmail). This causes considerable consternation among traditionally-minded dwarfs. She is an excellent scientist and a careful thinker, and her work on forensic evidence has transformed how the Watch investigates crime.
