It is the end of a long career, deemed venerable by those who admire Spanish fighting bulls.
In the early hours of Sunday morning, the half-tonne 11-year-old killer bull known as Ratón, or Mouse, will feel a bullring's sand under his hooves and sniff the scent of commingled human adrenaline and fear for the last time.
Those who pay their €2.50 (£2.20) in Canals, eastern Spain, will witness the final chapter of a life spent chasing, and occasionally goring, people. Fans are expected to arrive from around the country.
Many will be secretly hoping Ratón, who has killed two and reportedly gored five others in his career, will draw blood at his valedictory outing in the small town near Valencia. A fiesta poster promises "a show with the presence of the famous Ratón" starting at 12.30am. It does not mention that Ratón killed a spectator in nearby Xátiva last month and another man in 2008.
Canals mayor, Ricardo Cardona, claims to have been unaware of Ratón's bloody past when hiring him. He has asked the bull's owner, Gregorio de Jesús, to prevent members of the public coming face to face with the beast.
Four professional recortadores, or bull-taunters, will instead dodge in front of him in the bullring, encouraging him to chase them over obstacles for up to half an hour.
"It is when someone jumps in spontaneously that things inevitably happen," De Jesús said this month.
Police and security staff will try to prevent enthusiastic amateurs jumping into the ring with Spain's most infamous bull.
The future of Ratón, who is past retirement age, remains uncertain. De Jesús wants to clone the bull but is waiting to hear if he will receive local government funds to pay for it.
Bullfighting fans will shout "Ole" for the last time in Barcelona's Monumental bullring on Sunday before a ban on the sport takes effect across the northeastern Spanish region of Catalonia. The regional legislature banned the centuries-old tradition -- which pits a sword-wielding matador in a skin-tight shiny suit and red cape against an enraged bull -- last year after Catalans signed a petition against it. The bullfighting industry is still convinced it has a chance to overturn the ban and bring back the "toros" next season to Catalonia, the only mainland region in Spain that has blocked the sport -- or the art as its fans see it. "I think the politicians will think twice about the ban and bullfighting will live on. And thank God because Catalonia has plenty of serious bullfighting fans and in a democratic country they should be able to go to a bullfight," said Moises Fraile, 64, owner of El Pilar, the breeder supplying bulls for Sunday's spectacle. Some 20,000 spectators are expected to fill a sold-out Monumental -- the only bullring still operating in Catalonia -- for Sunday's blockbuster corrida starring celebrated Madrid "torero" Jose Tomas. Tomas retired in 2002, but came back in 2007 at a bullfight in Monumental, his favorite ring. Since then he has made sporadic appearances and is the only bullfighter who can still sell out Monumental.
