Several days ago, the Warner Bros. Studio Tour Hollywood official Facebook page posted video in which tour guide John Kourounis provided a live tour of the DC Universe: The Exhibit. When he got to the Batman V Superman: Dawn of Justice exhibit, he revealed that Jason Todd is indeed the dead Robin.
“This was one of the big things from Batman v Superman, right across this way. The Jason Todd/Robin suit,” Kourounis said. “Spray painted on the front, ‘Ha-Ha. The joke’s on you Batman.’ Those of you that know the storyline, know what happened to this Robin.”
In the 1988-89 “A Death in the Family” (Batman #426-429) story arc, The Joker kidnapped the second Robin, Jason Todd. He then tortured Jason, savagely beating him with a crowbar, and even made his estranged mother, Sheila Haywood, watch. Joker leaves them both to die in a warehouse rigged to explode. KaBOOM!
Jason Todd stayed dead longer than most comic book characters, and in 2005, DC Comics finally resurrected him, becoming the Red Hood.
