This is Crossiveri (pronounced "cross avery"), or Cross, a new original character of mine. He's, obviously enough, a demon - half mood demon, half gluttony demon.
He's a cute, spazzy little guy - his most notable ability is the ability to sort of "read" moods. Whenever he makes physical contact with someone, the black spots on his body will suddenly flare a bright color depending on that person's mood (vivid purple is contentment, pure white is sadness/regret, etc) and fade about a minute after the contact ends. His eyes, normally white, also change color depending on said mood. Due to only being half mood demon, he is unable to truly sense others' emotions and feel them for himself, so he has to rely on the sometimes vague readings of his spots (which leads to misunderstandings like reddish-pink meaning sexual lust/passion as well as hunger or a want for a specific item).
The other half, gluttony demon, gives him a unique diet - his ancestors lived off the fatty portions of animals and have adapted to actually benefit from excesses of fat and traditionally "unhealthy" things. In a nutshell, he only eats junk food, and is always carrying around snack food of some kind.
Okay, NOW I'm going to bed. I'll edit it later and cut out all that white space.
