In the main event, Bron Breakker defeated Ilja Dragunov and JD McDonagh in a triple threat match to retain the NXT Championship.

In other prominent matches, Mandy Rose defeated Alba Fyre to retain the NXT Women's Championship, and in the opening bout, Wes Lee defeated Carmelo Hayes, Oro Mensah, Von Wagner, and Nathan Frazer in a five-way ladder match to win the vacant NXT North American Championship.

[2] The event was scheduled to take place on Saturday, October 22, 2022, at NXT's home base, the WWE Performance Center in Orlando, Florida.

On the September 20 episode of NXT, McDonagh defeated Bate to earn another title match against Breakker.

Following the match, McDonagh was confronted by both Breakker and a returning Ilja Dragunov, who vacated the United Kingdom Championship due to injury.

[11] The following week, during another confrontation between the three, Breakker suggested a triple threat match for the NXT Championship, which was made official for Halloween Havoc.

[12] After defeating Carmelo Hayes to win the NXT North American Championship on the September 13 episode of NXT, Solo Sikoa, who replaced Wes Lee due to an attack by Hayes and Trick Williams,[13] was informed by Shawn Michaels that he was stripped of the title because he was not sanctioned to compete in the match.

After Sikoa was called up to the main roster on the SmackDown after debuting at Clash at the Castle two weeks prior, it was announced that Hayes and four other challengers would compete in a ladder match for the vacant championship.

[13] After Fyre played mind games with Rose over the next few weeks,[11][12] including kidnapping her in the parking lot,[14] the match was made official for Halloween Havoc.

[10] On the September 13 episode of NXT, The Creed Brothers failed to reclaim the titles from Pretty Deadly in a Steel Cage match after Kemp handcuffed Julius to the cage, leaving Brutus to fight Pretty Deadly alone.

[23] No matches took place on the pre-show, however, Halloween Havoc hosts Shotzi and Quincy Elliott appeared alongside Apollo Crews and Grayson Waller.

[24] The actual event began with the ladder match for the vacant NXT North American Championship, featuring Carmelo Hayes, Nathan Frazer, Wes Lee, Oro Mensah, and Von Wagner as the five participants.

In the closing moments, Lee performed a meteora on Hayes onto the ladder bridge and unhooked the belt to win the title for the first time.

[24] Following this, Toxic Attraction (Gigi Dolin, Jacy Jayne, and NXT Women's Champion Mandy Rose) pulled up to a haunted house.

As they explored the house, Alba Fyre dragged Jayne behind a curtain before slamming Dolin onto a table.

[24] Following this, footage was shown of Alba Fyre driving NXT Women's Champion Mandy Rose to the Performance Center.

The two then made their way to the elevated platform, where Perez performed a legsweep on Jade, causing both to fall through tables.

[24] Afterwards, footage was shown of a man burning a mask in a fire (possibly teasing the potential return of T-Bar to NXT under a new ring name).

[24] Next, The Schism (Joe Gacy, Jagger Reid, and Rip Fowler) cut a promo about masks and the other person following them.

Julius picked pumpkins to chuck at him and performed a dropkick on Kemp with the match officially starting moments later.

In the end, Julius powerbombed Kemp onto the stretcher before placing him in the ambulance and closing the doors to win the match.

Afterwards, Diamond Mine members Ivy Nile and Brutus Creed celebrated the moment with Julius.

[24] While the ambulance was leaving the Performance Center, Alba Fyre and NXT Women's Champion Mandy Rose continued their brawl, and their match officially began when they were in the ring.

In the climax, Fyre performed a Swanton Bomb, but Gigi Dolin and Jacy Jayne pulled the referee away.

[31] The Schism (Joe Gacy, Jagger Reid, and Rip Fowler) unmasked their newest member, which was revealed to be The Rock's daughter, Ava Raine.
