This character is not unlike Batman, The Dark Knight, from the DC comics. A brooding person who has been shaped from many of the bad experiences he had to deal within life. Hes had several personas in his lifetime. He was a mercenary. He was a rich man whose wealth was derived from his past as a mercenary. He was cab driver. And, he was Moon Knight, a seeker of vengeance and justice for the Egyptian god Khonshu. Each segment served a purpose and dealt with different people in different socio-economic strata. Each incarnation had their own identity to differentiate themselves amongst himself.
He crafted many of the tools that he needed as a superhero. Like Batman, he made things like throwing stars in the shape of the crescent moon and had the Mooncopter. He was equipped with a truncheon that can convert to numchuks. He wore a cape that gave him the ability to glide. All thanks to his wealth. Like Batman, he did not have any extraordinary powers but was very athletic. Later he would recieve special powers from Khonshu.
