This here is a marilith. Back in the day, (read: First Edition AD&D) we just called them type V demons, but apparently, someone decided that was overly analytical, or something. Also, they decided to stop calling them demons, so now mariliths are a type of tanar'ri.

Anyway, this one is clearly slightly upset about something, and is expressing that irritation in a polite and civil manner. no, really, I'm actually being quite serious. If she was actually mad, she'd be tearing into someone with weapons in all six hands.

I think these are neat to draw, but I don't do it very often because it's quite a challenge finding something for all their hands to be doing.
