Title: Batman: The Animated Series
Content:  Dick Grayson's history in the show mirrors that in the comics: The episode "Robin's Reckoning" reveals that Grayson and his parents were acrobats in Haly's Circus. Following the tragic deaths of Grayson's mother and father at the hands of mobster Tony Zucco, Bruce Wayne adopts Dick and eventually takes him on as a protégé. The series also redefined the original Robin/Dick Grayson. While much of Dick's past remains the same, his Robin costume is modernized with short sleeves and long tights, exactly like Tim Drake's original Robin outfit but with a non-italicized "R" symbol. In addition, Dick is given a more serious and mature personality to match the tone of the series (although he does have comedic moments occasionally). The episode "Batgirl Returns" establishes that Dick and Barbara Gordon attend the same college and that they are friends, but neither one knows the secret identity of the other. Their relationship is one of the plot elements of the film Batman & Mr. Freeze: SubZero.

Title: Dick Grayson
Content:  In this alternate reality, Nightwing ends an ongoing feud between super-powered beings by activating a device that depowers ninety percent of the super-powered population. This builds to a future where super-powers are outlawed and any super-powered being must take inhibitor medications or be contained and studied should the medications not work on them.

He becomes the leader of a government task force known as The Crusaders and hunts down super-powered individuals. In his off time, he raises his and Starfire's son, Jake, who soon develops his mother's powers and puts Dick at odds with the system he helped create. After allying with the Titans to help Jake escape, Dick tries to leave with his son, but Jake convinces him to aid the Titans and Superman in restoring the world's super-powers. Dick spent his remaining days watching his son grow into a responsible adult and teaching super-powered children how to control their abilities.
