My Very Own Superhero

This is a superhero I had imagined and ended up making. The story goes like so :

An ordinary man living an ordinary home, with an ordinary family, and... well... you get the point. He was  a blacksmith by  profession, which is why he looks so well built. One day, a demon disguised as a holy man, had come to collect the man's soul. The demon said to the man,"If you eat this flower, which I have plucked  from the highest tree in the hills, you will receive riches beyond your wildest dreams!" The man stared in amazement, at first, but later he decided that he should take the offer, so he ate the flower. The demon had then snatched his soul. The man pleaded for his soul back, and said he would give all his money to the demon for his soul back.The demon refused, but thought of another idea. He said,"I will return your soul, on the condition that you will become my apprentice and get me more souls." The blacksmith accepted his offer and gained the powers of a demon. So now this blacksmith collects the souls of those who have committed serious crimes against humanity, in order to get his soul back.
