A cross-border wrestling merger creates the first dual-promotion champions
In short: In September 2025, the worlds of American and Mexican professional wrestling collided in Las Vegas. This wasn't just a crossover; it was a structural merger that allowed a single athlete to hold top titles from two different continents simultaneously, marking a new era for global sports entertainment.
On 12 September 2025, the Cox Pavilion in Paradise, Nevada, hosted Worlds Collide. WWE and its Mexican partner, Lucha Libre AAA Worldwide (AAA), joined forces for this significant joint production. This partnership was solidified by a formal acquisition of AAA by WWE in April 2025, with the deal officially finalizing on August 1, 2025. The event was strategically scheduled during Mexican Independence Day weekend, a period of high cultural significance for Mexican combat sports.
The main event featured a historic milestone: Dominik Mysterio defeated El Hijo del Vikingo to capture the AAA Mega Championship. This victory made Mysterio the first wrestler in history to hold championships in both WWE and AAA at the same time. Other key results included El Hijo de Dr. Wagner Jr. retaining the AAA Latin American Championship in a fatal four-way match against Dragon Lee, Ethan Page, and JD McDonagh, and the team of Pagano and Psycho Clown retaining the AAA World Tag Team Championship against Grayson Waller and Kofi Kingston.
The event was part of a larger media strategy, livestreaming for free on WWE's YouTube channel with simultaneous English and Spanish commentary. It also functioned as a centerpiece for TKO Group Holdings' broader sports portfolio, which included a high-profile boxing match between Canelo Álvarez and Terence Crawford in Las Vegas and a 'Noche UFC' MMA event in San Antonio. While the matches were scripted and predetermined by writers, the storylines were developed over months of television programming across WWE's Raw, SmackDown, and NXT brands.
This specific iteration was the second Worlds Collide event held between the two promotions, following a previous event in Inglewood, California, in June 2025. It represented a significant expansion of the Worlds Collide brand, which originally launched in 2019 as an interbrand tournament for various WWE divisions.
