Batman-like champion?

Just saying. I do not think this could go wrong. A dark, brooding man of justice. Seeking the murderer of his parents. (Possibly Aatrox..? Or one of those ruthless, bloodlusting champions.) He wouldn't even "kill". Just seriously injure until they, "leave the hospital" xD I don't know. I just really like the DC universe. It would be cool to have a little nod in that direction.
