Alternate Universe - Space — Tag Meaning
Launches the cast off-planet into starships, space stations, colony worlds, or scrappy smuggling vessels. Some authors write rigorous science fiction, others want the romance of the void — long watches on a quiet bridge, the ship as a home, the crew as family — and earthbound canons get the biggest transformation from the jump.
What to Expect From "Alternate Universe - Space" Fics
Interstellar adventure or slow-burning shipboard intimacy, depending on whether the author loves plot or the vacuum-sealed bottle episode.

Alternate Universe - Science Fiction

Alternate Universe - Aliens
Introduces extraterrestrials into the premise — characters reimagined as aliens, first-contact scenarios, or abduction setups played for horror, comedy, or romance.

Alternate Universe - Future
Jumps the setting forward in time — sometimes a full sci-fi future, sometimes just the cast decades older in a changed world. It differs from 'Future Fic' in that it imagines an alternate future rather than a plausible continuation of canon: think the same characters reborn into a world that has moved on without their story ever happening.
