With the origin of Batman which is a story that we all know as Batman fans and DC comics fans. Bruce Wayne's parents Thomas an Martha Wayne were shot down by Joe Chill in Crime Alley and that traumatic experience made Bruce grow up and train to be the Dark, bruting, and smart Batman we know and love today. But with the multiverse in the DC universe it created other earths that had different versions of Earth Prime's (our earth) heroes like Superman, Batman, Wonder Woman, etc. On Earth-3 there was a team called the Crime Syndicate, which was the evil version of the Justice League which had the following members:
-Ultraman
-Owlman
-Super-Woman
-Power Ring
-Johnny Quick
-Sea King
-Deathstorm
-White Martian
-Grid
-etc
But the one I'm focusing on is Owlman, the evil Earth-3 version of Batman. Which the story is about.
