Worlds Collide (September 2025)

Worlds Collide, also known as Worlds Collide: Las Vegas, Worlds Collide II or Worlds Collide Dos, was a 2025 professional wrestling livestreaming event and supercard co-produced by the American promotion WWE and its Mexican sister promotion Lucha Libre AAA Worldwide (AAA). It was the fifth Worlds Collide under the WWE banner and the second between both promotions. It took place on September 12, 2025, at the Cox Pavilion at the Thomas & Mack Center in the Las Vegas suburb of Paradise, Nevada. The event featured wrestlers from WWE's Raw, SmackDown, and NXT brand divisions, and from AAA, which WWE acquired in April 2025.

The event marked the first time WWE has held two Worlds Collide events in the same year, following the June 2025 event in Inglewood, California. It aired for free via WWE's YouTube channel with both English and Spanish language commentary at 10pm EDT immediately after WWE's Friday Night SmackDown.

Six matches were contested at the event. In the main event, Dominik Mysterio defeated El Hijo del Vikingo to win the AAA Mega Championship, becoming the first wrestler to hold championships in WWE and AAA simultaneously. In other prominent matches, El Hijo de Dr. Wagner Jr. defeated Dragon Lee, Ethan Page, and JD McDonagh in a fatal four-way match to retain the AAA Latin American Championship, and Pagano and Psycho Clown defeated Grayson Waller and Kofi Kingston to retain the AAA World Tag Team Championship.
