Rodney Gaynor, born Rodrigo Gaynor, was a polo player and wealthy playboy from the eastern United States who was half-Mexican with a mother born in Guadalajara. Growing bored with his lifestyle, he turned to traveling across the country in which he visited Seguro, a small town in New Mexico. There, he was appalled by the living conditions of the poor farmers and the callousness of the landlords, and looked for a way to fight this injustice.
Rodney met Marissa Dillon, Seguro's local investigative reporter who also had Rodney's sense of justice, and through her he learned, from the local priest, about the legend of Don Fernando Suarez, who fought the corrupted Mexican land barons of the 1840's under the identity of "El Castigo" - The Whip. Inspired by El Castigo's adventures, Rodney decided to become the new Whip as he fought for the rights of the common man and, in time, began defending more of the American Southwest. In the course of his adventures, Rodney met and allied with the Vigilante, another Western hero, and later became a member of the All-Star Squadron.
Rodney continued his Whip persona until he eventually retired back to the American east coast and fathered a son. His identity eventually became public knowledge, though by that time few if any of his enemies survived, and the general public had little interest in his relatively minor fame. His last years were quiet ones.
His granddaughter, Shelly Gaynor, eventually took up the Whip identity with a radically different costume.
