Batman's sidekick Robin also appears, featuring a shaved head and contemporary costume design that were intended to move away from his traditional "Boy Wonder" image.

Senior concept artist Kan Muftic explained:

"Our vision of Robin is the one of a troubled young individual that is calm and introverted at times, but very dangerous and aggressive if provoked. The shaved head is inspired by cage fighters, because we thought that Robin might be doing that in his spare time to keep him on his toes. Still, we kept all the classic trademarks of Robin's appearance, such as the red and yellow colors of his outfit, the cape and the mask."
