New WWE Champion "Rowdy" Roddy Piper arrived on RAW with the screaming fans. The out-of-body experience. And of course, the beloved WWE Championship. Piper claimed that as champion, he will give it his all in every match and take on all challengers. That's when Randy Orton came out. The Viper stated that he has a guaranteed rematch clause and plans to use it at Backlash. Piper accepted. At Backlash, the first-ever Scottish-born WWE Champion would defend the belt against his former mentor. The next week, the two had a contract signing. Jerry "The King" Lawler moderated the signing. Orton said that for years, he trained Piper and said that his ego had always been so big, but this was the last stand. The Hot Rod claimed that The Legend Killer got what he deserved at WrestleMania, and that he'll cut his own legs just to end Orton's career at Backlash. The show ended with a brawl. A few weeks later, Piper was attacked by Undertaker and The Viper in a two-on-one assault. At Backlash, Orton and Piper would engage in a war unlike any other.
