Dominik Mysterio, currently reigning as WWE Intercontinental Champion, solidified his dominance across wrestling promotions by capturing the prestigious AAA Mega Championship in the main event of Worlds Collide on September 12, 2025. This win crowns him as a double champion, raising his profile dramatically within the global wrestling landscape.
Dominik Mysterio’s Ascendancy: From WWE to AAA Stardom
Since winning the WWE Intercontinental Championship at WrestleMania 41 in April 2025, Dominik Mysterio has continued to build momentum as one of WWE’s top rising stars. After a hard-fought fatal four-way match victory that marked his first singles championship on WWE’s main roster, he successfully defended the IC title multiple times against established competitors like AJ Styles and Bron Breakker, reinforcing his credibility and skill inside the squared circle[2][4].
Not content with reigning in WWE alone, Dominik made a bold move by debuting in Lucha Libre AAA Worldwide (AAA), WWE’s sister promotion in Mexico. There, he immediately positioned himself as a major threat by targeting the then-AAA Mega Champion El Hijo del Vikingo, setting the stage for a high-stakes clash at Worlds Collide[2][5].
The Historic Title Win at Worlds Collide
At the Worlds Collide event held on September 12, 2025, Dominik challenged El Hijo del Vikingo in a rematch for the AAA Mega Championship. Displaying tactical aggression and his ever-growing in-ring savvy, Dominik was able to outlast the Latin American star and claim the AAA Mega title, ending Vikingo’s reign and making history as the first talent to simultaneously hold WWE’s Intercontinental Championship and AAA’s top championship[5][3].
This victory is widely regarded as a significant milestone for Dominik, symbolizing his evolution from a legacy competitor into a bona fide global wrestling star. His dual-title status opens a wealth of storyline possibilities across brands, transcending geographical boundaries in professional wrestling.
Backstage Buzz and Future Prospects
According to a WWE insider, “Dominik’s double championship situation is a game-changer not just for him, but for WWE and AAA. There’s a clear intent to showcase him as a bridge between both promotions, elevating the profile of Worlds Collide as a premium integrated event. His reign over these titles will be central to cross-promotion storytelling moving forward.”
The insider also revealed that there may be plans for high-profile matchups involving Dominik’s legendary lineage, as his father Rey Mysterio is reportedly close to returning to television. Speculation is rife that a father-versus-son program, possibly a double-title bout, could headline an upcoming marquee event, potentially taking place in their hometown to maximize fan engagement[1].
The Judgment Day’s “Dirty” Dominik: Character and Impact
Dominik’s evolution into the “Dirty” Dominik persona has been instrumental in his rise. Turning his back on his father and aligning with The Judgment Day faction injected edge and complexity into his character, distinguishing him from his previous image as an underdog. This persona has generated intense crowd reactions and solidified him as a formidable heel within WWE storytelling[1][2].
His success outside WWE, especially in AAA, compounds his character’s depth, making him one of the most compelling figures in today’s wrestling scene. This trajectory reflects WWE’s strategic investment in younger talents who can excel across multiple markets and platforms.
Possible Rivals and Storylines Ahead
Dominik’s dual-title reign positions him as a magnet for challengers from both WWE and AAA rosters:
In WWE: Rey Mysterio’s anticipated return could ignite a deeply personal rivalry with Dominik, with the Intercontinental Championship symbolizing more than just gold but familial pride. Other contenders like AJ Styles and Bron Breakker remain in the mix for potential clash-ups[1][4].
In AAA: El Hijo del Vikingo is expected to pursue a rematch to reclaim the prestigious Mega Championship, igniting a fierce rivalry that showcases the generational clash of styles and personas within AAA[5][3].
Additionally, the cross-promotional dynamic opens doors for other top-tier matches involving AAA’s tag team and Latin American titles showcased at Worlds Collide events, enhancing the prestige and exposure for wrestlers from both promotions.
Conclusion: A New Era for Dominik Mysterio and WWE-AAA Collaboration
Dominik Mysterio’s capturing of the AAA Mega Championship while holding WWE’s Intercontinental title marks a defining moment in his career and the wrestling industry’s collaborative efforts. His dual-champion status not only enhances his personal brand but also strengthens the partnership between WWE and AAA, highlighting what integrated global wrestling entertainment can achieve.
As Dominik continues to carry both championships, fans can expect high-profile matches, compelling storylines, and important legacy moments in the coming months — potentially reshaping the future landscape of professional wrestling.
