It was the third and final Worlds Collide and while the event was held primarily for wrestlers from the promotion's NXT and NXT UK brand divisions, Worlds Collide also featured some wrestlers from WWE's main roster brands, Raw and SmackDown.

In other prominent matches, NXT Women's Champion Mandy Rose defeated NXT UK Women's Champion Meiko Satomura and Blair Davenport in a triple threat match to unify both women's championships, and Pretty Deadly (Elton Prince and Kit Wilson) defeated NXT Tag Team Champions The Creed Brothers (Brutus Creed and Julius Creed), NXT UK Tag Team Champions Brooks Jensen and Josh Briggs, and Gallus (Mark Coffey and Wolfgang) in a fatal four-way tag team elimination match to unify both tag team championships.

[8] On the August 23 episode of NXT, both Bate and Breakker signed a contract for a championship unification match to take place at Worlds Collide.

Later that night, Gallus interrupted NXT UK Tag Team Champions Josh Briggs and Brooks Jensen, and a brawl broke out, leading to a title match the following week,[8] where Gallus won via countout after Lash Legend attacked Fallon Henley, leading to Pretty Deadly (Kit Wilson and Elton Prince) brawling with Briggs and Jensen outside the ring, but Briggs and Jensen retained.

[9] On the August 30 episode, during a six-person mixed tag team match pitting Henley, Jensen, and Briggs against Pretty Deadly and Legend, Gallus interfered in favor of Legend and Pretty Deadly and helped them to win.

On the same episode, after Joe, Mark, and Wolfgang defeated Damon Kemp and The Creed Brothers, a brawl started between both teams, and Pretty Deadly, Briggs, and Jensen joined the fight.

Ricochet from SmackDown then appeared to challenge Hayes for the title at World Collide, which was made official.

Afterwards, they were attacked by JD McDonagh, who wanted another shot at the NXT Championship[11] after losing to Breakker at Heatwave.

[13] The Creed Brothers would continue their feud with Kemp over the next few weeks and on the October 4 episode, an ambulance match between Julius and Kemp was scheduled for Halloween Havoc, with the added stipulation that Brutus must leave NXT should Julius lose.

[14] For costing them the NXT Women's Tag Team Championship, Toxic Attraction (Gigi Dolin and Jacy Jayne) faced Doudrop and Nikki A.S.H.

Following the match, Mark, Joe Coffey, and Wolfgang attacked security guards and a referee before they were arrested as NXT ended.
