I’ve noticed this trend in a lot of DC projects, or at least the animated ones. In the 90s when Batman: The Animated Series was airing, they skipped over Jason Todd and had Tim Drake as the second Robin, instead of the third. I read somewhere at the time DC wanted to promote the current Robin at the time, Tim Drake. Also in a special feature on the BTAS DVD set, Paul Dini and Bruce Timm talk about Jason and how that version of Tim was a mixture of both Jason and Tim, and the reason they couldn’t have him was because his death quoting “…which was a very strong story and one that we couldn’t do in our series.”
In the current DC Animated movies universe, or the New52 movies, both Jason and Tim seem to never exist. I know they want to promote Damian, but I can’t help but wonder, are we losing those connection that have been established for years by just erasing them?
Dick Grayson’s status will remain unmatched as he’s been around almost as long as Batman has, but I’d really like to see the other Robins acknowledged currently.
