Alternate Universe - Police
Puts characters in uniform or detective shields: precinct partners, beat cops, internal affairs friction, the works. Partner dynamics carry the genre — two people trusting each other with their lives daily tends to accelerate everything else — and writers calibrate tone anywhere from Brooklyn Nine-Nine comedy to grim crime drama.

Alternate Universe - Noir
Lights the story in venetian-blind shadows: a world-weary private investigator, a client who's trouble, rain on the office window, and a city rotten from the top down. The genre is as much voice as setting — first-person cynicism, doomed romanticism — and writers relish casting canon's femme fatale energy wherever it fits best.

Alternate Universe - Spies & Secret Agents
Issues the cast codenames and cover identities: rival operatives assigned to seduce each other, handler/agent codependency, double agents lying to everyone including themselves. The genre inherits Bond's glamour and le Carré's paranoia in whatever ratio the author prefers, and trust — who has it, who's faking it — is always the real mission.
