The main feud heading into No Mercy was between King Booker , Bobby Lashley , Batista , and Finlay with the four battling over the World Heavyweight Championship . At SummerSlam , the pay - per - view two months before No Mercy , Batista defeated King Booker by disqualification after Queen Sharmell interfered , resulting in Booker retaining the World Heavyweight Championship . The next week on " SmackDown ! " , Batista along with Bobby Lashley defeated King Booker ' s Court ( Booker , Finlay , and William Regal ) in a 3 - on - 2 Handicap match . Booker ' s Court controlled most of the match , isolating Batista and Lashley from each other . Towards the end of the match , Lashley tagged in Batista , who ended up pinning Booker for the win after a Spinebuster . Two weeks later on the September 8 edition of " SmackDown ! " , Batista faced Booker for the World Heavyweight Championship , which Booker won after Finlay interfered and hit Batista with a shillelagh . After the match , Finlay continued to attack Batista with the shillelagh and a steel chair . The next week on " SmackDown ! " , Finlay began degrading Batista , saying he is probably hiding in a hole licking his wounds . As Finlay was about to continue , Lashley came out and said that only someone like him would jump Batista from behind . SmackDown ! General Manager Theodore Long then announced that , Finlay would face off against Lashley later that night to determine the number one contender to the World Heavyweight Championship at No Mercy . Lashley defeated Finlay and became number one contender after Finlay was disqualified for hitting him with a shillelagh . On the September 22 edition of " SmackDown ! " , Lashley teamed up with Batista to take on Finlay and Regal . Midway through the match , Batista and Finlay brawled outside the ring and into the crowd , leaving Regal on his own against Lashley . Lashley gained the pinfall after hitting Regal with a Spear . Later that night it was announced that Batista would face off against Finlay at No Mercy . Two weeks later on the October 6 edition of " SmackDown ! " , Booker faced off against Finlay and Batista faced off against Lashley , with both matches ending in a no - contest . This lead Theodore Long to make the one - on - one World title match at No Mercy , a Fatal Four - Way match . The other main match on the card was Mr . Kennedy versus The Undertaker . On the September 8 edition of " SmackDown ! " , Kennedy called out General Manager Theodore Long , and informed him that if John Cena comes to SmackDown ! , he wants a spot on Raw ; as Kennedy proclaimed that SmackDown ! didn ' t interest him anymore because he had already defeated every top performer on the roster . This led to Long booking a match between an opponent Kennedy had never faced , that opponent turned out to be The Undertaker . The match was scheduled to take place at No Mercy . On the September 29 edition of " SmackDown ! " , Kennedy presented a tribute to the Undertaker and tried to get out of the match . However , the Undertaker made his presence known to Kennedy , as he informed him , " I show no mercy , and you will rest in peace " . Kennedy attempted to strike the Undertaker with his microphone , but the microphone suddenly blew up in Kennedy ' s hand . The most personal feud was between Rey Mysterio and Chavo Guerrero . This feud started when Guerrero cost Mysterio the World championship at The Great American Bash , claiming that he was " a leech living off the blood of the Guerrero name . " Guerrero and Mysterio feuded for weeks , including a match at SummerSlam , where Vickie Guerrero accidentally cost Mysterio the match by knocking him off the top rope . The next week on " SmackDown ! " , Vickie attacked Mysterio and became Guerrero ' s new " business manager , " turning Vickie heel .
