The youngest of a family of acrobats known as the "Flying Graysons", Richard witnesses a mob boss named Tony Zucco kill his parents in order to extort money from the circus that employs them. Following the tragic murder, Batman (Bruce Wayne) takes Richard (Dick) as his ward and adopted son and trains him to become his crime-fighting partner Robin. He is written by many authors as Batman's first son. [1] In addition to being Batman's crime-fighting partner, Dick establishes himself as the leader of the Teen Titans, a team of teenage superheroes. As a young man, he retires as Robin and adopts his own superhero identity to assert his independence, becoming Nightwing. As Nightwing, he goes on to lead the Teen Titans and later the Outsiders, and becomes the protector of Blüdhaven, a financially troubled city near Gotham City, the place with which the character is most closely associated. He has also been depicted protecting the streets of New York, Chicago, and Gotham City over the years.
