Angel Fish (Earth-Twelve)

Atlantean Physiology: Angel Fish is a atavist, an evolutionary throwback with traits that were present in humanity's ancestors but are gone now. She can live and breathe underwater and has a fish tail instead of legs. This power was previously seen in the subspecies of humanity known as Merpeople.

Notes

Unlike the other members of FAN, Angel Fish is not a parody of an X-Men villain. Instead, she seems to have been introduced as a possible love interest for Awkwardman.
This version of Angel Fish, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths event and later restored following the rebirth of the infinite Multiverse during the Dark Crisis of 2022-2023. Even though other versions of the character may have appeared, this information does not apply to those versions.
