Adi as a human.
There's a lot to him, but i never really went in depth.
For one, he can control his hair. He's a shape shifter, but mostly uses just his hair to freak people out. He has an unhealthy obsession with rabbits, and he can control the Dark, which are little creatures made of paranoid thoughts, which grow and consume people's sanity.
They tend to take on the form of rabbits by default, but often will take shape of the creator's worst fears.

too much to explain

just enjoy the venty detailed goodness
