Road to WrestleManiaEdit
- Chris Benoit won the Royal Rumble and he swerved Smackdown General Manager Paul Heyman by defecting to the RAW brand to challenge HHH for the World Heavyweight championship. However, Shawn Michaels signed his name to the contract so it entitled him to participate in the match, or something. In reality, the title match between HBK and HHH ended in a draw at the Rumble so that's what entitled him to participate in the match.
- Riding a wave of increased popularity, Eddie Guerrero defeated Chavo at the Royal Rumble, then upset WWE Champion Brock Lesnar at No Way Out with outside interference from Goldberg. Kurt Angle won the opportunity to challenge Eddie through a mini-Rumble or tournament.
- Undertaker was eliminated from WWE at Survivor Series during a Buried Alive match when Kane interfered and dumped dirt on Taker in the plot. Months of harbingers preceded Undertaker's return, but Paul Bearer surprised most everyone when he joined Undertaker.
- As co-Raw General Manager, Mick Foley had been confronted by Randy Orton & Evolution numerous times. He contemplated returning to the ring, even consulting Shawn Michaels for advice, but it was a 3:1 attack and Rock's return that convinced him to accept a 3:2 handicap match against Orton, Flair, and Batista.
- Chris Jericho & Christian were best of friends, but a ill-fated bet to bag Trish Stratus or Lita caused friction between them. Eventually, they split (like a week or two before the match) and Trish Stratus double-crossed Jericho and aligned with Christian during the match.
- Continuing his WrestleMania tradition, Rey Mysterio wore attire resembling The Flash for the Cruiserweight Open. As a result, he went 0-2 in his first two WrestleMania appearances. After he abandoned the superhero tradition, he won his matches at WrestleMania 21 and WrestleMania 22. He would bring the tradition back at WrestleMania XXV.
- During Undertaker's entrance, the druids were carrying sticks of lit fire. One of the druid's stick was dripping fire on the electronic screen floor as he walked out, but men with fire extinguishers took care of it immediately. Kay was extra sensitive to the situation in attendance, scanning MSG for the nearest fire exit, because the Rhode Island fire was only 13 months earlier.
- More to be added
- Chris Benoit defeated Shawn Michaels and HHH in individual matches as well as another Triple Threat match the following month at Backlash before dropping the championship to Randy Orton at SummerSlam.
- Eddie Guerrero lost the WWE Championship in July to a recently repackaged JBL in a Texas Bullrope match where it seemed as though Eddie Guerrero had won the match, but it was determined that JBL's back hit the turnbuckle before Eddie's hand, so began his 10-month reign as champion.
- Undertaker "murdered" Paul Bearer at the first Great American Bash in a handicap match with Dudley Boyz where Paul Bearer was being encased in a concrete vault the longer the match lasted. In the end, Undertaker himself pulled the lever to release the rest of the concrete on his manager so he could focus on the match. WWE reported that Paul Bearer was NOT murdered, but simply suffered severe lung damage (or something). True to that story, an unmurdered Paul Bearer returned to WWE in 2010.
- After Randy Orton pinned Mick Foley, it sparked Foley's competitive spirits and Randy Orton defended his title against Cactus Jack the following month in a No Holds Barred match, which Orton won.
- True to the chants filling MSG, Goldberg and Brock Lesnar left WWE after WrestleMania XX. Neither man has appeared in WWE since that night.
- Chavo Guerrero lost his WWE Cruserweight championship to his father Chavo Classic in a triple threat match, but Chavo Classic lost the title to Jacqueline, and then Jacqueline lost the title back to Chavo. Rey Mysterio won the title from Chavo eventually.
