A scene in Batman v Superman: Dawn of Justice includes Bruce Wayne walking past the Robin outfit, which has been completely defaced by the Joker's message. We also catch a glimpse of Robin's weapon and you might have noticed its not the usual quarterstaff we are used to seeing in the comics.
The Tech Manual courtesy of Digital Spy shows that Robin's weapon had multiple blades and acted more like an ax than a staff. With the darker tone of the film, it only makes sense that Robin would arm himself in a more intense manner.
Speaking of Robin, we have no idea which one he is, but most people are betting on Jason Todd over Dick Grayson. Who do you think it'll be?
