Evilcoric

Evilcoric is a xenogender with three subsets. The main subset is a gender which embraces the 'evilness' of one's gender, for example almost in a reclaiming way of how non-binary people have been labelled as satanic in the past. The second is a gender that feels/is related to the pure androgynousness of a feral werewolf, also known as evil/werewolfcoric; and the third is a gender which feels/is related to hot-yet-coolness of vampires that is present in all genders, also known as evil/vampirecoric.

Flags
The flags don't have any specific meanings. The evilcoric flag was made to look Halloween-esque and the other two were made to look somewhat like the main flag and also like the subsets they're related to.

History
This term and the flags were both coined by Reddit user u/BowNonB.
