BRIEF Bio - Kain the Wanderer was raised by a very weird but peaceful and wise Cult in the American South West that practiced magical traditions and various different forbidden things, like homosexuality, "open marriage" etcetera. His name, Aaron Joseph Jameson comes from the names Aaron, Joseph and Jacob in the Bible, and he was devout in the Cult. One day he decided to leave the Order of Nod for Agnosticism, after various prophecies of the Order of Nod remained unfulfilled. His father and two brothers attempted to beat him and control him so he would remain in the Order, when he defended himself he beat them all to death in a rage, and accidentally caved in his sister, Mariah's skull, killing her, when she ran into the battle to help her brothers. He discovered the Mantle of Kain when he woke up after his battle, taking it as a sign that he should atone for his murders by becoming an arbiter of justice.

He took the name of Kain and wanders the world helping people and taking the mantle of vigilantism and heroism to atone for his sins. Since he has taken the Mantle of Kain, a mysterious Cloak of blood red garments, he has developed the powers of supernatural manipulation, including the power to control fire, to be supernaturally intelligent, and supernaturally strong and durable. He has unparalleled reflexes and perception, and as an investigator of crimes, his clairvoyance can uncover clues. Although his powers all come from the Mantle, taking the Mantle away would only make him weaker, not powerless, meaning he would still have his powers, just at a weaker state. He was already supernaturally strong from his devotion to Nod before leaving the Cult, even after he left. 

Key Differences - [how is the character different from the mainstream comics and cartoons/movies?] There isn't any. 
Notes - 
He is still Agnostic, but respects beliefs of others, even strange ones that he used to have.
