Dick Grayson was Robin, the sidekick and ward of Batman. He was orphaned when Boss Zucco killed his parents, John and Mary Grayson, who were circus acrobats. Starting out as the Boy Wonder, he used the moniker until well into adulthood, serving in the Justice Society of America and All-Star Squadron alongside Batman's daughter, Huntress. In his civilian life, he became a senior partner for Cranston, Grayson and Wayne.
