So here's a really cool database of Egyptian "demons." The name is a bit misleading to Western ears. These demons are actually helpful spirits, for all their ferocious aspect. Most of them were there to help protect Egyptians from evil influences. For example, the "bad guy" in the picture above is the bound humanoid figure, not the monster with the other monster ridin' on his back. Still, this is a valuable resource for anyone who likes making up monsters. Check it out.
