Alternate Earth, circa 1990s, but also including '80s roller skates, encounters of the sexy AND alien kind, and furries.
Alternate Earth, circa 1920s, gangsters, crime syndicates, murder, boxing, detectives...almost always raining. This genre is pretty much exclusively reserved for Connor
and his crew--which also features multiple Were-species, Vampires, Fae, Witches, and D/s action.
Cryptids, good and bad supernatural entities, and the agencies trained to deal with them.
Species who shift between full to half animal forms and human ones (part-time furries! LOL), including CatKynd, FoxKynd, Serpentians, and a number of varieties of Birbiankin and Gilled as well. The Shiftless
series is currently going here, though some of it takes place with steampunk technology and involves magic users as well.
Tiger's Catch - Novella
...Tentacles. Also featuring other less human-like species in Luridity. And tentacles.
Superheroes, superhumans, telepaths, elementals, and "mutants" not derived from biopunk engineering. Both training and persecution exist in this genre, depending on the planet, so check the tags first.
