Diablo was a black, adult male stallion that lived during the 1930s and 1940s. He was the trusted steed of The Whip (Rodney Gaynor) and shared in many of his adventures. Diablo's strength, speed and fierce countenance proved just as intimidating to adversaries as that of his master. Prior to Rodney's heroics, Diablo was a polo horse.
