Martin is an inborn mutant orphan who was adopted by two human couple after being found abandoned in the rails. He was named Martin and was cared and protected by his parents. A lot of people were terrified by Martins appearance and he never got proper education as most schools thinks he doesn't fit in with any other children and his adoptive parents were forced to home school him instead. Growing up, Martin finds it hard to adapt as he has very few friends who are either criminals or social outcasts. He joined his first gang when he was 15, he was used by the gang as their frontman as he was very naturally skilled with firearms. In one of their gang operations, they were caught by Brutus and Freddie Mcpyre from the S.H.S.A. He didn't go down without a fight, outsmarting the two officers and almost killing Freddie before being overpowered by other Superhuman agents. He was brought to a rehabilitation camp designed for criminal masterminds. Martin caused lots of trouble in the camp, beating two prisoners almost to death. Because of his outstanding skills with firearms, S.H.S.A. recruited him and told him the advantages of being a member. Martin refuses as he found it too pretentious of them to recruit him after all he's done. Instead, he joined with the group which fits him most. The Shadow Freaks, a bunch of outcast who works for those who can pay.

One of the most well-known researcher for his time, Jason made quite a lot of innovative inventions that made life easier for most people. His most controversial discovery is his experiments on wolves in an attempt to cross-breed them with humans in order to create a super-soldier with superhuman scents and speed. This caused many people to be outraged as they knew that his formula would be used with live humans. The formula is so close now that Jason is certain the test subject would be fine but that doesn't please the public, and he received threats from big corporations that if the experiment were to continue, his company would be shutdown and his reputation would be destroyed. Desperate but confident, Jason injected the formula into himself but as usual first tries, the formula went wrong. Instead, the wolf DNA overlapped his human DNA giving him the skin pigment and abilities of a wolf while maintaining his human intelligence and body. Now with a permanent hideous appearance, Jason was forced to shutdown his company and create a totally new identity. Jason framed his own death and now roams around the city anonymously as the Grayman. His potentials were not wasted as he now uses his skills with the Shadow Freaks where he feels home.
