I wrote a one-shot involving this villainous OC, and decided that he would be really cool to draw, despite the fact that he was just a glossed-over plot device.

Meet Nytemare.

He controls the mystic ooze-y stuff you see behind and around him. It's covered with smoky fog stuff, and for some reason, it's glittery. Upon contact with living things, it makes them see their worst fears. Kinda like fear toxin, I guess, but MAGIC. And it's ooze.
