On July 15, 2024, it was announced that NXT Halloween Havoc would return as a one-night livestreaming event. The fifth annual NXT Halloween Havoc, and 17th Halloween Havoc overall, was scheduled to take place on October 27, 2024, at Giant Center in Hershey, Pennsylvania, marking the first NXT Halloween Havoc to take place outside of the brand's home base, the WWE Performance Center in Orlando, Florida.[5][6]
The event comprised five matches that resulted from scripted storylines. Results were predetermined by WWE's writers on the NXT brand, while storylines were produced on WWE's weekly television program, NXT, and the supplementary online streaming show, Level Up.[7][8]
During NXT's CW premiere episode on October 1, a vignette aired with an unidentified wrestler approaching a road sign with the numbers "10" and "27". Several observers interpreted the vignette as indicating Australian wrestler Delta would debut at Halloween Havoc.[9][10] A follow-up vignette that aired on the October 22 episode revealed that Delta would perform in NXT, but under the name Zaria; she then appeared in person to close the show.[11]
At Heatwave, Ethan Page defeated Trick Williams to win the NXT Championship in a fatal four-way match which also involved Je'Von Evans, the latter of whom Page pinned.[12] Williams vowed to regain the championship from Page, which he did on NXT's CW premiere episode on October 1 with Raw's CM Punk as the special guest referee.[13] The following week, Williams celebrated his victory, only to be interrupted by Wes Lee, who stated that he would take the title from Williams. Later that night, Page blamed Punk for losing the title and demanded a rematch. At the end of the show, NXT General Manager Ava announced that Lee, Page, and Evans, the latter of whom Ava added to the match after being impressed by his performance against SmackDown's Randy Orton, would compete in a triple threat match the following week to determine the challenger for Williams at Halloween Havoc,[14] which was won by Page. After the match, Page spun the Spin the Wheel, Make the Deal wheel, landing on the Devil's Playground match, which was made official for Halloween Havoc.[15]
On the October 8 episode of NXT, Tony D'Angelo defeated Oba Femi to win the NXT North American Championship, ending Femi's reign at a record-setting 273 days.[14] The following week, D'Angelo celebrated his title win before Femi interrupted him. Femi announced that a rematch would take place at Halloween Havoc. Femi then spun the Spin the Wheel, Make the Deal wheel, confirming that the match stipulation would be a Tables, Ladders, and Scares match.[15] On October 22, NXT General Manager Ava announced that the match would only be decided by pinfall.[11]
On NXT's CW premiere episode on October 1, Roxanne Perez defeated Giulia to retain the NXT Women's Championship. In the closing moments, Perez attempted to use the championship belt to strike Giulia with it, only for a hooded individual to attack Giulia, costing her the match. After the match, the hooded individual was revealed to be the returning Cora Jade.[13] The following week, Jade stated why she attacked Giulia, feeling as if the fans forgot about her while she was recovering from her ACL injury and that she and Perez were working on mending their friendship. Giulia appeared, albeit with former rival Stephanie Vaquer by her side as a brawl ensued between the four women.[14] The following week, Vaquer defeated Wren Sinclair in her NXT debut match, only for Jade and Perez to ambush her before Giulia came to her defense. Vaquer and Giulia then challenged Jade and Perez to a tag team match at Hallowen Havoc, which was later confirmed.[15]
On the June 18 episode of NXT, Ridge Holland was accepted as an official member of Chase University despite initial pushback from Riley Osborne and Duke Hudson.[16] On the August 13 episode of NXT, Holland and Andre Chase defeated Nathan Frazer and Axiom to win the NXT Tag Team Championship[17] but lost the titles back to them at No Mercy. After the match, Holland viciously attacked Chase, defecting from Chase U and reverting to a heel in the process. Chase was subsequently strechered out of the arena and taken by ambulance to a hospital.[18] After his defection, Holland vowed to take down Chase U. On the September 10 episode of NXT, Holland defeated Hudson and took out Hudson with the barricade after the match.[19] On the October 15 episode of NXT, Chase returned to save Osborne from being taken out by Holland after their match.[15] The following week, Chase challenged Holland to an Ambulance match at Halloween Havoc, which was made official.[11]
Since September, Fatal Influence (Jacy Jayne, Fallon Henley, and Jazmyn Nyx) had been feuding with NXT Women's North American ChampionKelani Jordan, setting their sights on the title. On the October 22 episode of NXT, it was announced that Jordan would defend the championship at Halloween Havoc against one member of Fatal Influence; however, she would not know which member until the event. Later that night, Jordan prevented Nyx from interfering in Jayne and Henley's match against Giulia and Stephanie Vaquer, which they ultimately lost. After the match, Jayne spun the Spin the Wheel, Make the Deal wheel, landing on Spinner's Choice, allowing Fatal Influence to choose the stipulation for the match at Halloween Havoc, and they chose a Gauntlet match.[11]
