I want a superman who, after being bullied for so long because he had to show restraint when he didn’t have full control of his strength, doesn’t want anything to do with being superhero. He has very little faith in humanity and doesn’t think that they’re worth risking his life over. He decided to focus on his job as a investigative journalist and author.
He meet Bruce Wayne through his travel and manages to talk the man into an interview. Bruce normally wouldn’t take offers like this, but he had ulterior motives. He personally invites Clark to charity fundraisers, and eventually starts to befriend the man.
Through investigation Clark figured out that Bruce is Batman. He never reports on it. Once in a while he does pass off information to him about criminal activity.
Later, when Bruce is outside of costume, Clark takes a bullet for him during and attempted kidnapping, and ends up showing off more than a few of his powers.
Bruce thinks he should be a superhero, Clark refuses. It isn’t until a crisis that affects the world that he actually steps up to help the other heroes.
