Grayson Waller

On March 14, 2021, it was reported that Waller had signed with WWE. On the June 11 episode of *205 Live*, he made his WWE debut, defeating Sunil Singh. On the September 28 episode of *NXT*, Waller unsuccessfully challenged Roderick Strong for the NXT Cruiserweight Championship. On the November 9 episode of *NXT*, he lost to Solo Sikoa in a triple threat match which also included LA Knight.

On the November 23 episode of *NXT*, Waller berated the fans, thus turning heel. At NXT WarGames, he teamed up with Bron Breakker, Carmelo Hayes, and Tony D'Angelo as Team 2.0, where they defeated Team Black & Gold (Johnny Gargano, LA Knight, Pete Dunne, and Tommaso Ciampa) in a WarGames match. On the following episode of *NXT*, Waller brutally attacked Johnny Gargano during his farewell promo where he thanked his fans and friends, thus cementing his heel turn. On the December 21 episode of *NXT*, he attacked Dexter Lumis after the latter's match, and announced that he would dismantle the old *NXT* one by one. He then confronted AJ Styles in whom he had criticized on social networks a few days before. At NXT New Years Evil, Styles once again confronted Waller, resulting into a brawl between the pair. The following week on the January 11 episode of *NXT 2.0*, Waller lost to Styles. After the match, he was attacked by the returning LA Knight. On the February 2 episode of *NXT 2.0*, Waller, alongside his new "insurance policy" Sanga, interfered in Knight's match against Joe Gacy, causing Knight to lose the match. On March 8, during the NXT Roadblock special, he defeated Knight in a Last Man Standing match, albeit needing help from Sanga to beat the ten-count and get back to his feet.

At NXT Stand and Deliver on April 2, Waller faced Cameron Grimes, Carmelo Hayes, Santos Escobar and Solo Sikoa for the NXT North American Championship, a match which Grimes would win. Waller and Sanga would enter the tag team gauntlet match for the vacant NXT Tag Team Championships, where they were eliminated by the Creed Brothers. Waller then turned on Sanga and defeated him a week later on the April 19 episode of *NXT*. Waller then briefly feuded with the debuting Nathan Frazer, whom he lost to at NXT Spring Breakin'. Waller would then pursue the NXT North American Championship by tricking Carmelo Hayes into signing a contract. At NXT The Great American Bash, Waller lost to Hayes due to interference from Trick Williams and Wes Lee. Despite this, Waller blamed his loss on Wes Lee and defeated him on the July 26 episode of *NXT* due to interference from Williams. At NXT Deadline on December 10, Waller won the inaugural Iron Survivor Challenge to become the number one contender for Bron Breakker's NXT Championship. The match was later scheduled for NXT New Year's Evil on January 10, 2023, where the match ended when the middle rope snapped, causing Waller to fall out of the ring and be counted out, allowing Breakker to retain the title. A steel cage match between the two for the title was then subsequently scheduled for NXT Vengeance Day on February 4, which Waller would go on to lose.

As part of the 2023 WWE Draft, Waller was drafted to the *SmackDown* brand. He made his *SmackDown* debut on May 19, interviewing AJ Styles on his talk show, *The Grayson Waller Effect*. At Money in the Bank, Waller interrupted the returning John Cena, where he confronted and attacked Cena before getting hit with an *Attitude Adjustment*. On the July 7 episode of *SmackDown* in Madison Square Garden, Waller interviewed Edge on *The Grayson Waller Effect*. Waller then made his main roster in-ring debut later that night in a losing effort against Edge. On the November 10 episode of *SmackDown*, Waller and his new tag team partner Austin Theory provoked the newest member of the *SmackDown* roster Kevin Owens, leading to Owens attacking both Waller and Theory. On the December 15 episode of *SmackDown*, both Waller and Theory lost in the first rounds of the United States Championship number one contender tournament to *NXT*'s Carmelo Hayes and Owens respectively. Waller returned to NXT at NXT New Year's Evil on January 2, 2024 and was put into a match against Trick Williams for Williams' Iron Survivor Challenge title match opportunity by Hayes. Waller lost the match after interference from Owens.
