Dick Grayson was born into a family of circus acrobats called the Flying Graysons. He was trained by his parents to perform amazing feats of agility and skill. When he was eight years old, a mobster named Tony Zucco sabotaged their trapeze act, causing his parents to fall to their deaths. Bruce Wayne, who witnessed the tragedy, took Dick under his wing and adopted him as his son. He was originally a circus acrobat whose parents were killed by a mobster. He became Batman’s first sidekick, Robin, and fought crime with him in Gotham City. He later grew up and became his own hero, Nightwing, operating in Blüdhaven.
