The World Heavyweight Championship (2007–2008)

Undertaker won his first Royal Rumble match after [[Shawn Michaels]] attempted Sweet Chin Music, and Undertaker ducked and lifted Michaels over the top rope for the victory. He became the first man to enter the Rumble at number 30 and win the match. He then began an angle with [[Batista]], whom he defeated at [[WrestleMania 23]] to win his first World Heavyweight Championship. On the next SmackDown!, Batista entered the ring and declared that he wanted a rematch in the form of a Last Man Standing match at [[Backlash]]. The rematch ended in a draw when neither man was able to answer the ten-count after Batista speared Undertaker off the entrance stage, causing the steel pillars to fall on top of the two men, resulting in the Undertaker retaining the Championship. On the May 11 SmackDown! taping, Undertaker had a Steel Cage match with Batista that was booked to result in a draw when both men's feet touched the floor at the same time. After the match, [[Mark Henry]] returned and assaulted the defenseless Undertaker. Immediately after the assault, [[Edge]] cashed in his Money in the Bank title shot, and Undertaker dropped the World Heavyweight Championship to Edge. As Undertaker laid in the ring, druids appeared and carried him to the backstage area. In reality, Calaway had suffered an arm injury that required surgery, but WWE did not want to break the Undertaker's character by having him forfeit the title. During Calaway's rehabilitation, Henry squashed local jobbers and bragged about his assault on Undertaker, until vignettes began playing promoting Undertaker's return. The Undertaker returned at [[Unforgiven]], successfully defeating Henry with a Last Ride from the corner and again on SmackDown! two weeks later with a chokeslam. Batista and Undertaker re-ignited their storyline feud at Cyber Sunday where the fans chose guest referee [[Steve Austin]], but Batista retained the world title after two Batista Bombs. They battled again inside Hell in a Cell at Survivor Series where Edge returned and interfered by giving Undertaker a con-chair-to and pulling an unconscious Batista on top of Undertaker for the pinfall to retain the World Heavyweight Championship. In response to this, Undertaker delivered a Tombstone piledriver to General Manager [[Vickie Guerrero]], on the next SmackDown!, in storyline, sending her to the hospital. Returning Assistant-GM [[Theodore Long]] declared a Triple Threat match for the title at [[Armageddon]]. Edge won the match by pinning Batista, who had been given a Tombstone piledriver which was followed by Undertaker being hit with a chair while he attempted the pinfall. At [[No Way Out]] 2008, Undertaker defeated Batista, [[Finlay]], [[The Great Khali]], [[Montel Vontavious Porter]], and [[Big Daddy V]] in a SmackDown/ECW Elimination Chamber, to become the number one contender for Edge's World Heavyweight Championship at [[WrestleMania XXIV]]. He defeated Edge at WrestleMania with his gogoplata submission hold, to win his second World Heavyweight title and elevate his undefeated streak at [[WrestleMania]] to 16-0. In a WrestleMania rematch, The Undertaker defeated Edge once again at Backlash to retain the World Heavyweight Championship. The Undertaker battled Edge for the title at Judgment Day, which he won but could not keep the title because of the count out victory. The two faced each other again for the championship at One Night Stand in a Tables, Ladders, and Chairs match, which Undertaker lost. As a result of the [[Kayfabe|storyline]] stipulation, Undertaker was banished from WWE.
