An incubus is the male version of the female succubus. An incubus is a male demon that preys on women through sex. Their power is their sexual attraction. A succubus. drains seamen from a male in order to steal his power and create more demons, (or so I've read), I don't know what an incubus is supposed to do to a woman...? Something involving sex at any rate. Either way, this is a friendly creature, but not a good one.
I imagine that his phallic colouring should suggest his nature adequately!

Skinny bugger, isn't he?
