#3. Never beaten Roman Reigns: The Undertaker
The Undertaker and Roman Reigns have only crossed paths once in a singles match in WWE, and this came in the main event of WrestleMania 33 in 2019 in a No Holds Barred match.
The WWE Universe believed this would be The Deadman's final match after he was defeated by Reigns, but he made several returns before officially retiring in 2020.
The Undertaker and Roman Reigns originally crossed paths in 2013 when The Shield were able to defeat Daniel Bryan and The Brothers of Destruction on an episode of RAW.
The two men have since shared the ring twice. The duo teamed up with Braun Strowman on an episode of SmackDown to defeat Baron Corbin, Elias and Kevin Owens.
The Undertaker and Reigns later decided to team up one more time as part of WWE's Extreme Rules pay-per-view. On this occasion, the two men were victorious when they overcame the team of Drew McIntyre and Shane McMahon.
The Deadman made the decision to retire from WWE after more than three decades at Survivor Series in 2020 and is still yet to defeat Reigns in singles or tag team match.
