Wrestle Mania 23 - Aftermath

Aftermath

John Cena and Shawn Michaels continued their feud, with Michaels betraying Cena the night after WrestleMania on Raw. During the second of two battle royals, Michaels eliminated himself and Cena, resulting in The Hardys winning the World Tag Team Championship. On the Raw before Backlash, Cena and Michaels wrestled an almost hour long non-title match, which Michaels won.

Batista also continued his feud with The Undertaker, facing off against him in a Last Man Standing match the following month at Backlash. The match ended in a draw after both men failed to answer the ten count, therefore resulting in Undertaker retaining the title. The two faced each other in a Steel cage match on the May 11, 2007 edition of SmackDown!, which ended in a draw after both men escaped the cage at the same time. The feud ended when The Undertaker dropped the World Heavyweight Championship due to a legitimate injury. Edge, who won Kennedy's Money in the Bank contract in a match on Raw the previous Monday, cashed it in and defeated The Undertaker after the Steel cage match to win the title.

Bobby Lashley's feud with Vince McMahon continued for a further three months after the event. Vince, livid after being embarrassed at WrestleMania, vowed to destroy Bobby Lashley and take his ECW Title. At Backlash, Vince, his son Shane and Umaga teamed up a Three on one handicap match against the champion, and after two Samoan Splashes by Umaga from the top rope, Vince pinned Lashley to win the title. The feud continued for a further two pay-per-views, with Lashley pinning Shane in a repeat match from Backlash at Judgment Day, but Vince ruled that as he didn't get pinned, Lashley didn't win the title. At One Night Stand, Lashley finally defeated Vince in a Street Fight to reclaim the championship.

The match between Chris Benoit and Montel Vontavious Porter expanded into a lengthy feud for the WWE United States Championship, resulting in Benoit retaining via pinfall at Backlash and Porter winning the title in a Two out of three falls match at Judgment Day, winning 2–0.

The feud between the ECW Originals and the New Breed continued, with the New Breed defeating the Originals in an Extreme Rules match on the next edition of ECW. Sabu was released from the company shortly after WrestleMania, and The Sandman was drafted to Raw a few months later in the 2007 WWE Draft. Kevin Thorn left the New Breed shortly after WrestleMania and Marcus Cor Von was also released shortly thereafter. By this point, Elijah Burke and Matt Striker had ceased associating with one another, with Striker eventually being relegated to a manager role for Big Daddy V. In addition, Rob Van Dam left the company when his contract expired shortly after One Night Stand. As a result of all of this, the feud eventually puttered out and was rarely mentioned again.

Unfortunately, Mr. Kennedy never got the chance to cash in his Money in the Bank contract. A few weeks later on Raw, Edge argues with Mr. Kennedy and challenged him to a match, convincing him to put the briefcase on the line. Later, when Mr. Kennedy was heading to the ring, Edge attacked Kennedy on the entrance ramp and pummeled him. Against the official's suggestion, Kennedy shook his head, agreeing to start the match. Just after the bell rang, Edge gives Mr. Kennedy a spear, gets the pin and becomes the new Mr. Money in the Bank. Just a few days later on SmackDown, after the Undertaker was brutally attacked by Mark Henry, Edge successfully cashes it in on a beaten Taker and becomes the World Heavyweight Champion once again.
