Dick Grayson was an 8-year-old acrobat and the youngest of a family act called the "Flying Graysons". A gangster named Boss Zucco, loosely based on actor Edward G. Robinson's Little Caesar character, had been extorting money from the circus and killed Grayson's parents, John and Mary, by sabotaging their trapeze equipment as a warning against defiance. Batman investigated the crime and, as he alters ego billionaire Bruce Wayne, had Dick put under his custody as a legal ward. Together they investigated Zucco and collected the evidence needed to bring him to justice. From his debut appearance in 1940 through 1969, Robin was known as the Boy Wonder. Batman creates a costume for Dick, consisting of a red tunic, yellow cape, green gloves, green boots, green spandex briefs, and a utility belt.
