Secret Identity — Tag Meaning
Splits a character between public face and hidden truth — masked heroes, undercover royalty, spies in suburbia — and builds the story on maintenance of the wall. The genre's compound interest comes from relationships conducted across it: loving someone who only knows half of you, and the mounting cost of every lie that protects them.
What to Expect From "Secret Identity" Fics

Identity Porn
Fandom's term — not inherently explicit, despite the name — for plots that luxuriate in identity confusion: a character romancing both halves of someone's double life without knowing they're one person, or two masked figures each oblivious to the other's civilian face. The dramatic irony is the product; Superman built the template and fandom industrialized it.

Alternate Universe - Superheroes/Superpowers
Grants powers and capes to casts that never had them, building hero/villain economies from scratch. Writers love the genre's double-identity machinery — dating a civilian while moonlighting in spandex, nemeses who don't recognize each other unmasked — and power assignment becomes character commentary, like daemon-choosing with lasers.

Secret Relationship
The couple is real; the world doesn't know. Whether hiding from teammates, press, families, or hostile institutions, the secrecy shapes everything — stolen moments, cover stories, the strain of public distance. Authors mine both the thrill of the hidden and the cost of it.
