On November 23, 2008 at Survivor Series, Edge returned to WWE after an introduction by SmackDown General Manager and his on-screen wife Vickie Guerrero, replacing Jeff Hardy in the Triple Threat match for the WWE Championship involving champion Triple H and Vladimir Kozlov. He pinned Triple H to become the WWE Champion for the third time in his career. The following month, Edge lost the title to Hardy at Armageddon in a Triple Threat match, which also featured Triple H. At the Royal Rumble, however, Edge regained the title in a no disqualification match, following Matt Hardy's interference. At the February event No Way Out, Edge lost the WWE title in an Elimination Chamber after being pinned by Jeff Hardy, being the first to be eliminated, with the title eventually being won by Triple H. Later that night, Edge inserted himself into the World Championship Elimination Chamber match after attacking Kofi Kingston and barricading himself inside one of the Chamber's pods, proceeding to win his eighth World Championship, last eliminating Rey Mysterio and taking the title over to SmackDown. At WrestleMania XXV in April, Edge lost the championship to John Cena in a Triple Threat match, which also included The Big Show. Three weeks later he regained the championship at Backlash, when he defeated Cena in a Last Man Standing match, after interference by The Big Show. After a successful defense against Jeff Hardy at Judgment Day, he lost the title to Hardy at Extreme Rules in a ladder match, and afterwards said some disparaging things to his on-screen wife, Vickie Guerrero. While Hardy was celebrating, CM Punk cashed in his Money in the Bank and defeated Hardy to win the World Heavyweight Championship. The following night, Guerrero resigned as the Raw General Manager due to being humiliated, and Edge came out to apologize. Instead, however, he claimed he married Guerrero because she had authoritative powers as the General Manager, and sought a divorce. On the June 15 episode of Raw, Edge received his rematch for the World Heavyweight Championship in a triple threat match against both Hardy and Punk, but was pinned by Punk.
