For the sake of plot...mostly Raven's powers. Maybe some animalistic agility and pale green skin.

Some partial form changing would be super cool. Like, not whole animals just.. claws, horns, wings, scales for protection, etc.

People are racist for a reason.
Being poor depressed alcoholics is completely another matter.

>>#65, The drinking and depression stem from the poverty. And it's not that bad. People just like complaining and pretending shit's worse than it is.

Adoption? Who the fuck would want to adopt a mongtard?
"Yes, I'de like to adopt that one. The one thats 32 years old and drooling out of both sides of his mouth. That one there, with the vacant expression and shitty diaper on him"

Literally the only people I can think of are;

A)
A person who adopts him, just to murder him/lock him up and collect the welfare checks.

B)
A person who adopts him, just to have a mentally retarded sex toy to abuse however they wish.

It probably wouldn't be long-term adoption so much as it would be a good individual(s) caring for him until he became a legal adult, and then he could be placed in a home for professionals to care for.
