Demon boy with nothing but time
Asmodeus has abilities ranging from amateur, manipulating smoke, steam, mist, fog, to masterful, controlling a human's mind. He's unable to force humans to do anything, but he can influence their decisions. He can alter certain parts of the brain, causing madness for as long as he's controlling them.
A prized Demon in the underworld, Asmodeus has seen his fair share of blood and gore and it appears as if it's gotten to his mental state - or is it just a facade?
Before imprisonment Asmodeus did the dirty work for anyone who paid and is known for playing with his food.
