Picking up from the ashes of SON OF BATMAN, BATMAN VS ROBIN pits father against son in one of the most dysfunctional family dynamics that could be imagined.
Damian Wayne (Stuart Allan) is a ten-year-old assassin, trained by the best in the business. His bloodlust is potentially inborn, what with having Talia al Ghul as a mother. United with his father, Bruce Wayne (Jason O'Mara) for the first time has been tumultuous at best, as Damian is eager to accompany his father in the battle against crime as Batman and Robin. Only this Robin has to be reined in to keep him from killing the bad guys.
As BATMAN VS ROBIN opens, Robin has gone off on his own in search of some missing children taken by The Dollmaker ("Weird Al" Yankovic). It is during this encounter that Robin meets Talon (Jeremy Sisto), who fights like Batman but isn't timid about crossing the line of taking lives. He offers Robin an opportunity to join him, which Robin begins to seriously consider.
