Like Son of Batman, the new Batman vs Robin adapts a popular comic book story arc, but it deviates far more from the original story. In this case, Scott Snyder’s Batman monthly comic story generally known as The Court of Owls has been used as a concept for the villains of the animated film, and for certain sequences here and there, but otherwise it’s mostly been rewritten from that concept into a brand new story. Damian didn’t feature in Snyder’s tale, and it was much more Gothic and mythical. Fans will have to accept that this isn’t an actual adaptation of the comic book story, and merely took inspiration from the comics while building a brand new unique story of its own. Damian is really the main character, and the focus is on whether he will remain loyal to Bruce/Batman or slide back to his old ways when tempted to join the Court of Owls’ assassin squad know as Talons.
