My nom. I meant Arrowverse, but AO3 wouldn't accept it when I tried using that. It gave the error where it said that it was a freeform tag, which is really weird since Arrowverse has been used as a fandom in other exchanges.

Shows involved: Arrow, Flash, Legends of Tomorrow, Supergirl, Constantine, The Ray, Vixen. Technically the 90s Flash TV show based on an Easter Egg where they show bits of other universes.

Black Lightning is currently not part of the Arrowverse but they haven't ruled the possibility out of adding it in.
