DC Comics was left uncertain about readers' decision to have Jason Todd killed, wondering if readers preferred Batman as a lone vigilante, disliked Todd specifically, or just wanted to see if DC would actually kill off the character. In addition, the 1989 "Batman" film did not feature Robin, giving DC a reason to keep him out of the comic book series for marketing purposes. Regardless, Batman editor Denny O'Neil introduced a new Robin. The third Robin, Timothy Drake, first appeared in a flashback in "Batman" #436 (1989).
