There have been a few moments in the Batman mythos that have been truly memorable, have truly changed the landscape for the fans. (If you ask Robert Greenberger, there are at least 100 of these, but that's a review for later this week.)
One such moment came in 1999, when a new animated series took Batman into the near-future; where Bruce Wayne (KEVIN CONROY) is a retired octogenarian, and Terry McGinnis (WILL FRIEDLE) as the latest heir to the mantle, in a New Gotham that has a whole new set of problems.
When we are introduced to the series, Bruce is wearing the jet-black, tricked-out costume. But his age is catching up with him, and his heart isn't holding up. When he finds himself grabbing a dropped gun to defend himself against a common thug, he's horrified at what he's doing, and seals up the Batcave for good.
