Zack Snyder’s fiercely-anticipated Justice League Snyder Cut has indicated that Robin’s mysterious death at the hands of Batman’s arch nemesis Joker will be further addressed. The death of Robin, aka The Boy Wonder was first highlighted in Batman v Superman: Dawn of Justice where his suit was put in a display case by Bruce Wayne in the Batcave.
Now, the director has teased that there might be some more backstory attached to Robin’s death. On the social media platform Vero, Snyder confirmed that Dick Grayson died prior to the events of Dawn of Justice and that it is his suit that hangs in the Batcave. This was in stark contrast to Suicide Squad director David Ayer’s comment who gave the impression that Jason Todd was dead. A fan asked Snyder, “Did you have plans to dive deeper into the background of Dick's (Grayson) death in your future movies? Maybe JL?"
Snyder also revealed that he had plans to show Grayson’s death in Justice League. However, it’s not clear whether he was referring to Justice League that was released by Warner Bros. or his canceled Justice League Part 2.
Robin has been conspicuous by his absence in the DCEU series of movies. Robin aka Dick Grayson was created by writer Bill Finger and artist Bob Kane. He first appeared in Detective Comics #38 in April 1940. Robin outgrew his person in July 1984 and eventually became Nightwing in Tales of the Teen Titans #44.
