Alternate Universe - Dark — Tag Meaning
Signals a universe deliberately crueler than canon — heroes corrupted, hope rationed, institutions rotten. It functions as both premise and warning label: authors apply it so readers know the moral floor has been lowered, and it frequently travels with archive warnings and 'Dark [Character Name]' tags that deserve attention before reading.

Alternate Universe - Villain
Flips a hero to the dark side and explores the world that choice creates — sometimes a single divergence that curdled into villainy, sometimes a from-birth reimagining.

Alternate Universe - Dystopia
Builds an oppressive regime around the characters — surveillance states, caste systems, rigged games, forbidden emotions — and watches them comply, break, or rebel. Fanfic dystopias often borrow the furniture of 1984, The Handmaid's Tale, or The Hunger Games while keeping the focus tight on how the system grinds against one relationship.

Angst
One of the foundational tags of fanfiction, covering stories centered on emotional pain — grief, longing, guilt, heartbreak, despair.

Alternate Universe - Mob
Reorganizes the cast into organized crime: dons and capos, enforcers and accountants, loyalty oaths and territory wars. The canonical tag covers mafia AUs broadly, and the genre splits between glamorous danger-romance — falling for the boss — and grimmer studies of violence, debt, and the impossibility of getting out.
