Though an original character with nothing more than the birth name "Robin", Blake displays many similarities with a couple of incarnations of the character Robin, particularly **** Grayson. Like Grayson, Blake lost his parents as a child, ended up in an orphanage, became a police officer before retiring later to become a vigilante crimefighter, and eventually became an ally of Batman to stop a common enemy. He also has similarities with Tim Drake, as he deduced Batman's secret identity while still a child and has shown considerable faith in Batman's abilities despite his choices and actions. In addition, like Jason Todd, Blake expressed extreme rage over the loss of his parents.
