Well he was of course the heart of the Bat-books in the 90s as I said during the O'Neil editorial years. He was the POV character in Detective Comics during his run, plus the Robin book (and any of the Dixon comics of that era which was most of the Bat books for a time). TTGO is Dick but never referred to as such, he's just "Robin" but his costume is the Tim one. It's silly because these aren't really different people, and DC doesn't want them to be. They just want "Robin." Unfortunately for the brand, you have all of these characters with histories and each has their own little fiefdom of fanatics.
What's the point of Robin? Not the in-universe explanation for the character origins. What's the point of having Robin the character?
