Justice League, Season Four

Amanda Waller:
But when you're making a Batman, genetics is only part of the story - the rest is tragedy.

Amanda Waller:
Stop me if you've heard it before - you're eight years old. Your parents have just taken you to a rousing adventure film - a grand time is had by all.

Amanda Waller:
But unknown to you, a mysterious figure hides in the shadows. My plan was simple - the killer would leap out at you and kill your family. The trauma would put you on the path to becoming Batman. One problem - my assassin wouldn't pull the trigger.

[Phantasm backs off and leaves unnoticed; cut to Phantasm with Waller]

Amanda Waller:
I argued with her, but deep down, I knew she was right. People say Batman's obsessive, that he'd do anything to achieve his goals - but he'd never resort to murder. So if I was to honor all he stood for, neither could I.
