Three female superheros in black and purple costumes standing next to each other

Fantasyish, Deltarune themed. Make a "shadow crystal" holder aka a secret boss. Something that could be based off the 90s if Hawkins Indiana, a town in the 90s had a 90s themed dark world. The character is a humanoid, but aren't human. Probably a cyborgnetic vampire like creature or something of the likes. The character has a purple and dark blue, and a dark black and gray asthetic. Hood is usually up and he rocks a mask of sorts, the mask being kinda V shaped or like visors. A mask with eye sockets and the sharp edges of the mask poke out. He has void black sockets on the mask but glowing white eyes with purple diamond shaped eyes. Top of head has a 3 crowned like asthetic. Basically a vigilante of the night. Think something like Bat Man but if Bat Man had magic abilities. Oh and purple spectral wings. Also no skin or anything as they are not a human but a darkner. So make something that a player could fight in Deltarune. Object reference could be based off of torn and tossed comics and superhero figurines.
