Christian Montcouquiol was the brother of Alain Montcouquiol, a bullfighter known as "Nimeño I". From 1975 to 1982, Christian appeared in arenas in Spain, France, and Latin America under the direction of Spanish promoter Manolo Chopera. In 1982, Christian separated from Chopera and turned to his brother Alain for management.
On May 14, 1989 in Nîmes, Nimeño II and Portuguese torero Victor Mendes were scheduled to fight six bulls. Mendes was injured early in the match, and Nimeño II won renown for defeating all six bulls single-handedly.
On September 10, 1989 in Arles, Nimeño II was hurled into the air by a bull named Pañolero. He landed on his head, fracturing his cervical vertebrae and suffering paraplegia. After months of rehabilitation, Nimeño regained the use of his legs and right arm, but his left arm remained paralyzed. On November 25, 1991, Nimeño II committed suicide by hanging himself in his garage.
The bullfighting arenas of Eauze and Caveirac are named for Nimeño II. There are commemorative plaques to Nimeño II in the arenas of Arles, Mont-de-Marsan, and Béziers in France, and Aguascalientes in Mexico. At the arena in Nîmes, a statue of Nimeño II (above) was erected, and the annual "Trophy Nimeño II" is awarded there to the leading novillero without picadors. The street in front of the Béziers arena is named "Plaza Nimeño II".
