Ratón ("Mouse" in English) was a
Spanish fighting bull that was nicknamed
el toro asesino (the killer bull),
el sangriento toro (the bloody bull) and
el terrible Ratón (the terrible Mouse) for killing three people in
bullfighting rings in Spain between 2006–11 and injuring thirty more. The bull became legendary in Spain due to the large number of gorings for which he was responsible. Bullfighting fans regarded him as a star and traveled from across the country to see the
morlaco (big bull) at his home at
Sueca near
Valencia.
Matador Jesús Esteve said of Ratón: "He is a killer. He is lazy, he doesn't want to participate. He does his own thing, waiting for somebody to make a mistake. And then when he gets you, he wallops you, and he doesn't let up."
