No Mercy (2005)

No Mercy (2005) was the eighth annual No Mercy professional wrestling pay-per-view event produced by World Wrestling Entertainment (WWE). The event, presented by Sony's PlayStation 2, took place on October 9, 2005 at the Toyota Center in Houston, Texas and featured wrestlers and other talent from WWE's SmackDown! brand. Nine professional wrestling matches were scheduled on the event's card.

Three of the four championships exclusive to the SmackDown! brand were contested for; one was lost while the other two were retained. The main event was a standard wrestling match, in which World Heavyweight Champion Batista defeated challenger Eddie Guerrero to retain his title. One of the featured preliminary matches was a Casket match between The Ortons (Randy and "Cowboy" Bob) and The Undertaker. The Ortons won the match after placing Undertaker inside the casket and closing it. Another primary preliminary match was a standard match between John "Bradshaw" Layfield (JBL) and Rey Mysterio, which JBL won.

The event received 219,000 pay-per-view buys, which was greater than the 193,000 buys the previous year's event received. The event was claimed to be "unmerciful" by Canadian Online Explorer's professional wrestling section, as they rated none of the matches higher than a five out of ten. When the event was released on DVD, it reached a peak position of fourth on Billboard's DVD sales chart for recreational sports. It remained on the chart for four consecutive weeks.
