I’m trying to run down the original source of a quote for a little writing project (non-fictional in nature, more on the order of an essay than a fanfic, hence the need for a source) I’m putting together. I may have found it, but my source reads like it’s quoting something else, so I’m trying to figure out if it’s a reference to another story.
In Nightwing #127, Dick’s narration quotes Batman as saying “Your mind is your greatest weapon. Don’t ever forget that.” This comes up several times, but with no associated flashback, and the first time it appears he doesn’t specifically say that it comes from Batman. So, it sounds like it’s something from an earlier story, presumably one involving Bruce training Dick as Robin. I figured Batman: Year Three was the most likely candidate since both it and Nightwing #127 are written by Marv Wolfman, but I just skimmed through and found some similar quotes, but neither the exact one nor anything quite so pithy that I could use as a substitute.
Anybody recognize this? I could just quote the Nightwing issue, but I’m trying to use the quote to make a point about Batman, so it would be odd to quote a different character’s series on the subject.
