Grayson has also taken on the identity of Batman on a few occasions. He has also been depicted as protecting the streets of New York, Chicago, and Gotham City over the years.

He is written by many authors as the first son of Batman. After the tragic murder, Batman (Bruce Wayne) takes Grayson in as his legal ward (retconned as an adopted son in some cases) and trains him to become his crime-fighting partner Robin.
