Juan Kachmanian (April 6, 1930), better known as Pampero Firpo, is a retired Argentine professional wrestler of Armenian descent. Having been trained by Rudy Dusek, he made his debut in 1953 and wrestled variously as Ervan the Armenian, Ivan the Terrible, The Missing Link, The Great Pampero and the Wild Bull of the Pampas, as well as his most famous alter-ego of Firpo (named after the original, Luis Ángel Firpo). An early pioneer of Hardcore wrestling, Kachmanian usually wrestled as a heel, although he would go on to have a run as a face after being fireballed by The Sheik. Other notable feuds in his career would include Nick Bockwinkel, Alberto Madril and Apollo Jalisco.
