Memory Alteration — Tag Meaning
Goes beyond erasure into editing: memories implanted, rewritten, or selectively trimmed by magic, technology, or institutional malice. The trope carries inherent violation — someone decided what another person gets to remember — and fanfic uses it for everything from mind-wiped operatives reclaiming their pasts to the ethics of erasing someone's worst day for their own good.
What to Expect From "Memory Alteration" Fics
Gaslight-adjacent unease and recovery arcs; discovering the edit is usually the story's detonation point.

Memory Loss
The broader memory tag, covering everything from trauma-suppressed years to magically stolen moments to degenerative forgetting.

Amnesia
One of fiction's great engines, thriving in fanfic: a character loses their memory, and everything — identity, loyalty, love — must be rediscovered or re-earned. Writers use it to replay first meetings, test whether love survives forgetting, or let a hardened character meet the world fresh.

Mind Control
Subjects a character's will to someone else's — hypnosis, brainwashing, magical compulsion, parasitic influence — and reckons with the violation. Fanfic uses it for plot (the controlled teammate turned weapon) and for aftermath (recovery from having been driven like a vehicle); the Winter Soldier made the deprogramming arc one of fandom's central traditions.

Identity Reveal
Detonates the secret: the mask comes off, by choice, accident, or catastrophe, and the fic deals in the blast radius. Reveal fic is a whole subgenre in Miraculous Ladybug, Spider-Man, and Merlin fandoms, with taxonomies of reveal types — voluntary, forced, deathbed, witnessed-by-the-wrong-person — each carrying its own emotional physics.
