Diamondback

"You quote the Bible like you actually believe in God." "And you speak to me as if you're not in the presence of death."

- Mariah Dillard and Diamondback

Willis Stryker is the half brother of Luke Cage who slowly became angered by their father's treatment of him and eventually became a criminal under the alias of Diamondback. Finding his brother in Harlem, Diamondback used Hammer Industries weapons to try and kill Cage while also controlling the criminal organisations of Harlem by working with Black Mariah. Diamondback attempted to frame Cage for multiple murders until choosing to kill him himself, only to be defeated and arrested, however Noah Burstein decided to use Diamondback as a test subject to recreate Cage's powers.

Early Life
Willis Stryker was born when his mother, Dana Stryker had an affair with James Lucas, a preacher who she was working as a secretary for. However Lucas refused to leave his wife and therefore rejected Stryker, having his own son named Carl Lucas two years later. Lucas' mother was thought to be unable to have children, leading to Lucas being called, The Miracle Baby, something that enraged Stryker as the truth about him also being the preacher's son was kept hidden from everybody, including Lucas whom Stryker became friends with.

When the young Carl Lucas was beaten up in front of a bowling alley by another teenager, Stryker helped train Lucas how to box by taking him to a gym in Savannah. Even though he told Lucas that he had nothing to prove to anyone, Lucas remained determined to prove himself as a skilled fighter, noting that he was part of the proud Lucas family which only annoyed Stryker more, although he kept quiet about his own relation to Lucas. Stryker basically taught Lucas how to fight, reminding him to keep focused on his breathing while he threw his punches.

A few years later, Stryker and Lucas stole a, just for a joyride and discussed music, with Stryker noting he liked and Lucas liked. They were pulled over by police and arrested. Lucas and Stryker's dad convinced the judge to let Lucas go so he could join the Marines. As for Stryker, he was put in juvenile detention where he was soon attacked and killed the inmate in self defence and sent to prison. Hating both Lucas and their father, Stryker vowed revenge but did not know that Lucas was sent to prison.
