Injustice's Knight (Injustice x Male OC)

I'm gonna be going in the comics route rather then the movie or game. I'll also focus more of Batman and Superman sides then with characters like superboy and that stuff. I'll also change a few things so it makes sense in the story.

Ryan Grant use to work for the milita during his years in being in the military. His skills are on par with the Batman. His skills in combat and his marksmanship had earned him the spot as commander, he used his spot as commander to make his Arkham Knight suit. He eventually left the milita after a few years since he no longer wanted to kill and wanted to live a peaceful life. But on the day his brother's life was on the line and he was forced to go back to his old ways after black mask figured out who the Arkham Knight was and what he could do. He was forced with a task to kill the Batman but during his hunt to kill the Batman, he had been convinced by him that he could do good and it didn't have to end with violence. They attempted to save Ryan's brother but unfortunately for Ryan, black mask had killed his brother. After the defeat of black mask Ryan had attempted to kill black mask but was stopped by Batman. Batman offered him some help and every night they had worked together which led him to be apart of the bat family and Batman revealing his identity to him. He got to know the bat family and was a big help and even worked with the justice league when Batman asked him for help when the justice league needed a few extra hands. He even earned a spot in the justice league. But what will happen when the joker tricks Superman into killing his wife and unborn child? You will need to read and find out.

I DO NOT own any of the Dc characters or the Arkham Knight suit. I only own the character ryan and will use the Arkham Knight suit because in my personal opinion think that it's a really cool suit. the rights to the other characters in this story belongs to Dc. The images that I will use in this story belongs to the respective owners.
