Memphis

-gets mistaken for a bat or a dragon 

-is usually covered almost head to toe in old baggy clothes so as not to be easily outed as demon

-permanently disgruntled. keeps to himself. lacks any drive to hurt others. barely interacts with others. introverted. is fairly quiet. always looks annoyed.

-his powers are pretty much the same that SPN demons have: doesnt need to sleep or eat. able to move living bodies. able to possess others. able to create portals to hell. able to be summoned. immortal. able to see souls.  

-left hell out of spite after learning he wasn't born a demon but was a mortal transformed into one. using his powers strengthens his connection with hell, so he only uses them as a last resort. the longer he goes without using them, the more 'free' he becomes.

-has adopted a vagabond life and spends almost all his time playing video games and getting stoned.
