The Jalpa of 1982 was named after a bull breed; Diablo, after the Duke of Veragua's ferocious bull famous for fighting an epic battle against "El Chicorro" in Madrid in 1869; Murciélago, the legendary bull who survived 28 sword strokes and whose life was spared by "El Lagartijo" for his performance in 1879; Gallardo, named after one of the five ancestral castes of the Spanish fighting bull breed; and Reventón, the bull that defeated young Mexican "torero" Félix Guzmán in 1943. The Estoque concept of 2008 was named after the estoc, the sword traditionally used by "matadors" during bullfights, while the replacement for the Murcielago, the Aventador (unveiled in 2011) was named after a bull that was bred by the sons of Don Celestino Cuadri Vides. This bull was killed in a particularly gruesome fight, where after the bull was killed, its left ear was cut off and given to the Matador as a token of good luck.
