Azrael

-An Oneiroi, feeds off emotions from dreams. Has the ability to give dreams but prefers nightmares. He likes the taste of fear over other emotions.
-Has a cherubic face but not the personality to match it. In fact, his personality is kind of the opposite?
-He doesn't understand human emotions besides fear, and doesn't make an effort to understand it because he views humans the same way one would view cattle.
-Doesn't usually show up in people's dreams, but his true form can only be seen when within a dream. Otherwise, the form most people see is a short man with curling horns, and curly brown hair. His true form is a gluttonous, white leech with a large mouth where his stomach should be. When eating, his colors change based on what he eats (usually turning black due to fear). His true form is definitely more nightmarish than his human form. He seems to prefer this nightmare form, and is unhappy that he can't use it in the physical realm.
-In a distant way, his kind are related to Succubi and Incubi. Though he feels superior to them, since Oneiroi are definitely more closely related to Gods than Succubi and Incubi are. Refers to them as gutter trash. In retaliation, a lot of them tend to try and steal his prey because they find it funny. Which it is, just not for him.
-Arrogant. He views most other beings as beneath him in a way, and ugly. He's pretty unbearable to be around due to his ego. Can be slightly useful due to his powers, but too much trouble to convince him to help.
-His views of ugly isn't based on any physical, superficial appearances. That is to say, he finds people with power extremely attractive. Only respects those he recognizes as stronger than him.

Do you have to be so ridiculously vain all the time?
