Nothing to Fear was the first episode of Batman: The Animated Series to feature Bruce Wayne’s past prior to becoming Batman. Throughout the episode Bruce struggles with guilt (brought on by Scarecrow’s fear toxin and a cruel comment from one of Thomas Wayne’s colleagues) over whether his father would be proud of the man he has become. Alfred Pennyworth tells Bruce that his fears are “rubbish,” and that he knew Thomas would undoubtedly be proud of Bruce because Alfred himself is so proud of him.
But it’s not until later in the episode that Bruce conquers his fears when faced with a toxin-induced hallucination of Thomas and utters the iconic quote:
No! You are not my father! I am not a disgrace!
I am vengeance, I am the night, I am Batman!
