Does anyone remember when the first version of Jason Todd as Red Hood appeared, and in what issue or story event?
I was thinking maybe the first 52 event, but it may have been before, or after.
This Red Hood was from another Earth, I do not remember which one. He shows up at least a few times in other comics after that, but that version of the Red Hood was clearly dropped and a new version of the character, with a different origin replaced him.
I have that comic in my collection, but it might take a day, or several, to find the right book, since I have more than 5000 + comics to search though.
Mostly though, it is a matter of finding the right two boxes, and then finding the right set of books within… unless he appears in one of the comic book title issue, and not in one of the mini or maxi series books.
I checked Wikipedia, but the first appearance was clearly edited out, like someone wanted there to be no trace left of that first version of the Red Hood. There is no mention of that Red Hood in the DC Universe Encyclopedia either.
