Miles was born eighteen years ago to two wealthy business people (his father is now the CEO and founder of a major technology company, while his mother is CEO of a military weapons company. However, both businesses were relatively small at the time of his birth).
It was quickly realized that he was a brilliant child, a genius in fact. He was so smart he finished secondary school at age fifteen, and at age eighteen, he is already a polymath and a polygot.
Miles had an easy childhood, having two extremely wealthy people for parents, but he always pushed himself to his limits in everything he took part in and never let money change how he viewed others.
His mutant power emerged when he was thirteen, when he turned his body into concrete, after he touched a wall in his house. His parents were incredibly surprised, but they didn't really mind, provided that he never told anyone randomly, and that he never used his powers to hurt others.
Miles agreed with his parents' wishes, and immediately starting experimenting his powers, analysing out his strengths and weaknesses.
He spent his entire thirteenth year practicing his powers. At age fourten, he tried using his powers as a hero, coming out some nights and fighting crime. Most of the criminals were regular humans, which he quickly defeated. After a while, at age fifteem, he donned a costume and eventually became known to all the criminals. However, once, age sixteen, he met up with an agent of Weapon X, and got in a fight with him.
The agent, Nathanial Moses, defended himself, but ended up getting a scar across his left cheek, before he escaped. Soon after this, Miles was contacted by the
50 State Iniatative, who asked him to join their group. Miles accepted the offer, and eventually worked his way up their ranks, until he became part of their main group.
