Background in
St. Louis,
Missouri.
Backlash is a recurring
professional wrestling event that was established by
WWE in
1999. It was held annually from 1999 to
2009, but was then discontinued until it was reinstated in
2016 and has been held every year since, except in 2019. The original concept of the event was based around the backlash from WWE's flagship event,
WrestleMania. The events between 2016 and
2020 did not carry this theme; however, the
2021 show returned the event to its original concept. On March 14, 2025, WWE announced that the 20th Backlash, promoted as "Backlash St. Louis", would take place on Saturday, May 10, 2025, at the
Enterprise Center in
St. Louis,
Missouri, and feature wrestlers from the
Raw and
SmackDown brand divisions. In addition to airing on traditional
pay-per-view (PPV) worldwide and via
livestreaming on
Peacock in the United States, the event was available to livestream on
Netflix in most international markets and the
WWE Network in any remaining countries that had not yet transferred to Netflix due to pre-existing contracts. This marked the first Backlash to livestream on Netflix following the WWE Network's merger under the service in January 2025 in those areas. Tickets went on sale on March 21 via
Ticketmaster. while storylines were produced on WWE's weekly television shows,
Monday Night Raw and
Friday Night SmackDown. In the main event of Night 2 of
WrestleMania 41,
John Cena won the
Undisputed WWE Championship to become a record 17-time WWE world champion. On the following
Raw, Cena gloated about his win only for his long-time rival
Randy Orton to attack Cena with an RKO. On
SmackDown that Friday, as Cena was about to cut another promo, he was interrupted by Orton, who tried to reason with the now villainous Cena, who had turned
heel at
Elimination Chamber: Toronto back in March. After an exchange of words, Orton challenged Cena to a match for his championship that night; however, Cena declined, stating that the match should happen in Orton's hometown of St. Louis at Backlash. The match was subsequently made official, and was billed as "One Last Time". Prior to Night 1 of WrestleMania 41,
Bayley, who was supposed to team up with
Lyra Valkyria for a
WWE Women's Tag Team Championship match on Night 2 of the event, was found attacked backstage by an unknown assailant, requiring Valkyria to find a new partner. On Night 2,
Becky Lynch made a surprise return as Valkyria's mystery partner and they won the Women's Tag Team Championship. On the
Raw the night after WrestleMania 41,
Gunther came out and argued with commentators
Michael Cole and
Pat McAfee as Gunther felt disrespected by them following his loss at WrestleMania. Gunther then attacked Cole which led to McAfee attacking Gunther in Cole's defense, however, Gunther managed to overpower McAfee and choked him out. The following week, McAfee wanted to fight Gunther and asked SmackDown's General Manager
Nick Aldis, who was subbing for Pearce that night, to lift Gunther's suspension. Aldis declined and instead proposed a match between them at Backlash, which McAfee accepted. and a day later at Night 2,
Drew McIntyre defeated
Damian Priest in a
Sin City Street Fight. At Night 2 of WrestleMania 41,
Judgment Day's
Dominik Mysterio won the
Intercontinental Championship in a
fatal four-way match also involving
Penta and Mysterio's stablemate
Finn Bálor, the latter of whom he pinned. ==Event==
