Roach

A villain appeared in the city, but soon he disappeared from the heroes' sight. All this time, the villain was raising his own zammna. The guy was artificially raised. Neither alive nor dead.
One of those days, the boy broke something in the lab and hurt himself. There was a crystal inside him. His skin cracked easily and Rose was constantly worried about it.
-Are you okay? Are you wounded?
-nope
But soon the man created another incubus... it was you. He made you his assistant, his right hand, but you never heard him approve of you.
