No Mercy was a professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE), which took place on October 7, 2007 at the Allstate Arena in Rosemont, Illinois. It was the 10th annual No Mercy event and starred wrestlers from the Raw, SmackDown! and ECW brands. Nine professional wrestling matches were scheduled on the event's card, which featured a supercard, a scheduling of more than one main event. The first main event featured wrestlers from the Raw brand in a Last Man Standing match—a match where the first person unable to respond to a ten count by the referee lost—between WWE Champion Triple H and Randy Orton. Orton won the match and became the WWE Champion. The other main event featured wrestlers from the SmackDown! brand, in which defending World Heavyweight Champion Batista defeated challenger the Great Khali in a match in which a large wooden structure known as a Punjabi Prison surrounded the ring. Two featured bouts were scheduled on the undercard. In a standard wrestling match between wrestlers from the Raw brand, WWE Champion Triple H defeated Umaga to retain his title. The other was a standard match between wrestlers from the SmackDown! brand in which Finlay and Rey Mysterio fought to a no contest.
