My god there are a lot of Robins these days! I grew up with Dick Grayson/Robin. That was it, kids. You had the live action TV show and the cartoons and the comics but they were all Dick Grayson. Then along came Jason Todd, Tim Drake, Stephanie Brown, and Damian Wayne. That’s without even touching on the others such as Carrie Kelly from the Dark Knight. I had to go to the DC wiki just to make sure I had them all straight.
But you know what? I’m fine with all of that. I have no problem with heroes “passing the torch,” with someone new taking on the heroic identity of a familiar character. It is one way to tell new stories without having to change the existing character’s personality in odd ways (I’m looking at you Man of Steel movie.) To be honest, I haven’t read any comics with Stephanie Brown or Damian Wayne in them. Not because I think they’re not the real Robin but because I have drifted away from the mainstream comic world. Life goes on, things change. A new Robin does nothing at all to harm the great memories I have of the one I grew up with. The newer versions are thrilling and entertaining people as well. I see nothing wrong with any of that.
