Come to think of it, I'm a bit surprised that nobody, so far as I know, has ever done a story that introduced the audience to Batman through the eyes of Dick Grayson (or another Robin) being brought into his life, discovering his identity, and so forth, the way most versions of the X-Men have used a new student as the viewpoint character for the audience (Jean in the comics, Kitty in the failed TV pilot, Jubilee in the '90s series, Nightcrawler in Evolution, Rogue and Wolverine in the movies). I mean, Robin was created to be an identification character for kids, so you'd think one of the many, many Batman animated series might have started out from his POV.
(Naturally Titans doesn't count, because that focuses on the adult Dick Grayson after he walked out on Batman.)
