Rag Doll is a generational legacy name used by several super-villains. The original was Peter Merkel, a triple-jointed contortionist who committed crimes while dressed as a children's toy. He has been a member of the Injustice Society and the Secret Society of Super-Villains. The second Rag Doll was Colby Zag, who used the title to act as a serial killer. Peter Merkel, Jr. later became the third Rag Doll as a member of the Secret Six. Despite not being triple-jointed like his father, he achieved incredible flexibility through a series of complicated surgeries. Rag Doll was created by Gardner Fox, first appearing in Flash Comics #36. (1942)
