Edge and The Undertaker's rivalry in the late 2000s is one of the most underrated rivalries in WWE history. The feud between both men kicked off in 2007 when the Rated-R Superstar cashed in the Money in the Bank briefcase on The Undertaker for his first World Heavyweight Championship. Unfortunately, Edge got injured in July which put their feud on standby.

Nevertheless, the Rated-R Superstar returned emphatically at Survivor Series getting himself involved in Undertaker and Batista's Hell in a Cell match. Ultimately, Edge and Undertaker have competed in a plethora of high stake matches including a TLC and Hell in a Cell. Both men played an integral part in SmackDown's success with a feud that encapsulated their greatness, facing each other in marquee matches that had varying levels of quality.

7 SmackDown (May 11, 2007)

The Undertaker retained the World Heavyweight Championship in a violent steel cage match with Batista on the May 11, 2007 edition of SmackDown. Both men climbed over the cage with their feet touching the floor simultaneously. The match ending in a draw favored the champion. However, Undertaker was viciously attacked by Mark Henry moments after the cage was raised.

The Ultimate Opportunist had captured the Money in the Bank briefcase from Mr. Kennedy on the previous edition of Raw and wasted no time in seizing the opportunity. Edge delivered a Spear to The Phenom and captured his maiden World Heavyweight Championship, which acted as the catalyst for their exceptional feud.

6 Judgment Day 2008

SmackDown General Manager Vickie Guerrero stripped The Undertaker of his World Heavyweight Championship in May 2008 for his repeated usage of the Hell's Gate submission hold. At the upcoming Judgment Day event, Undertaker and Edge clashed for the vacant title.

It wasn't the best encounter between the pair but it was another strong match. The Rated-R Superstar executed his patented Spear on Undertaker with the Phenom barely kicking out. The two fought outside with the Deadman getting the better of Edge by winning the match by count-out. Furthermore, Vickie abused her power once more by stating that the title could only change hands by way of pinfall or submission with the title still vacant.

5 Backlash 2008

Edge invoked his rematch clause at Backlash 2008 after dropping the World Heavyweight Championship to The Undertaker at WrestleMania XXIV in a magnificent main event. Edge continued to assert his dominance in this match by controlling the early portions of the championship bout.

Curt Hawkins and Zack Ryder even tried to interfere on Edge's behalf to no avail, as Undertaker swatted them aside with ease. He then applied the debilitating Hell's Gate submission hold on Edge in a highly competitive match. The Phenom wanted to inflict pain and refused to break the hold with the Rated-R Superstar bleeding from the mouth and eventually being carried out on a stretcher.

4 Armageddon 2007

Edge made his long-awaited return to the ring at Survivor Series 2007 in the latest chapter of Batista and Undertaker's exceptional rivalry over the World Heavyweight Championship. The Ultimate Opportunist took out The Phenom in his Hell in a Cell match which allowed the Animal to retain the title.

The Rated-R Superstar got himself involved in a high-profile World Heavyweight Title match at Armageddon against Batista and Undertaker in a triple threat match. All three men had an exceptional outing that proved why they were the blue brand's greatest stars.  Curt Hawkins and Zack Ryder interfered to help Edge succeed in his quest to regain the World Title. Undertaker executed a Tombstone Piledriver on Batista but Edge clocked him with two chair shots in the back and face before pinning Batista for his fourth World Championship.

3 One Night Stand 2008

The stakes were as high as ever by the time One Night Stand 2008 rolled around. Vickie Guerrero had an ultimatum for The Undertaker - if he failed to capture the vacant World Heavyweight Championship in Edge's specialty; a TLC match, he would be banished from WWE.

Unfortunately, La Familia's repeated interference stopped this match from being a great one. Edge and Undertaker still delivered on a high level with Edge putting The Deadman through a table with a splash by jumping off the announce table. The Deadman responded with a devastating Last Ride on Edge through two tables. Alas, the Master Manipulator recovered by pushing Undertaker through four tables which were stacked on top of each other. He climbed up the ladder and regained the World Heavyweight Championship with Undertaker banished from WWE.

2 SummerSlam 2008

Hell hath no fury like a woman scorned, with Vickie Guerrero enraged at Edge for cheating on her with their wedding planner Alicia Fox. Vickie got her revenge by reinstating Undertaker, and she put Edge in a Hell in a Cell match with the Demon of Death Valley at SummerSlam in 2008.

This was the final one-on-one match between the two and they had another remarkable contest. The crowd was heavily invested in this match and wanted to see Edge get his comeuppance for putting Undertaker through hell. Thankfully, there was no interference and Edge proved his credentials as a certified main eventer. Undertaker won the match after dropping Edge with a jaw-dropping Tombstone Piledriver. However, Undertaker was not done there as he grabbed a ladder and put Edge on it, then Chokeslammed him through the ring canvas.

1 WrestleMania XXIV

The Undertaker won the SmackDown Elimination Chamber match at No Way Out 2008 to earn the right to challenge Edge for the World Heavyweight Championship. The Master Manipulator headlined WrestleMania for the first time in his career, going toe-to-toe with The Undertaker at WrestleMania XXIV.

Undertaker was appearing in his first WrestleMania main event of the last 11 years, and more than made up for his disappointing clash with Psycho Sid at WrestleMania 13. The Rated-R Superstar shook out the nerves on his way to the ring as he realized how big the task at hand was. Edge came extremely close but left himself wide open by delivering a Spear with Undertaker playing possum and locking Edge into the Hell's Gate. The Phenom captured his sixth World Championship with Edge succumbing to the submission hold in a match that captivated the audiences.
