Dominik Mysterio made history on September 12, 2025, by adding the prestigious AAA Mega Championship to his accolades, becoming a double champion while retaining the WWE Intercontinental Title. The milestone occurred at the Worlds Collide event in Las Vegas, where Dominik defeated El Hijo del Vikingo in a thrilling main event. This victory marks Dominik’s first world championship and cements his status as one of the most dominant rising stars bridging WWE and Lucha Libre AAA Worldwide (AAA)[1][3].
Dominik Mysterio’s Historic Double Championship Win
At Worlds Collide, Dominik engaged in a brutal and high-flying contest against El Hijo del Vikingo, AAA’s reigning top champion. The match was a showcase of their athleticism and resilience, featuring a flurry of near-falls and signature maneuvers like Vikingo’s 450 splash and Dominik’s Three Amigos suplexes. The encounter spilled outside the ring and displayed the dramatic back-and-forth momentum expected in a marquee title fight.
A turning point came when Dominik’s faction, Judgment Day, intervened. Finn Balor, JD McDonagh, and El Grande Americano each played pivotal roles: McDonagh disrupted Vikingo with a headbutt, Balor handed Dominik his iconic lucha mask, and Americano orchestrated a clever distraction involving a metal plate hidden inside the mask. This distraction allowed Dominik to execute a decisive frog splash after a 619, securing the victory and the AAA Mega Championship[1].
The Significance of Holding WWE and AAA Titles Simultaneously
Dominik Mysterio now stands alone as the first wrestler to simultaneously hold major singles titles in both the WWE and AAA promotions. While dominant in the WWE’s United States-focused landscape as Intercontinental Champion since WrestleMania 41, earning him credit as one of WWE’s premier rising stars, capturing the AAA Mega Championship represents his rise on the global stage of Lucha Libre wrestling[3].
Sources close to WWE revealed backstage excitement over this milestone. “Dominik’s unique position as a double champion reflects WWE’s evolving partnership with AAA. It’s a rare honor and a huge opportunity to showcase his versatile wrestling style to a broader audience,” shared a WWE insider[1].
Judgment Day’s control over multiple championships—including world tag team titles held by Balor and McDonagh, as well as women’s titles—demonstrates the faction’s ascendancy in 2025. Dominik’s win continues this dominance and signals a storyline push for the group across both wrestling worlds[2].
Aftermath: A Tense Father-Son Moment
Post-match, WWE Hall of Famer Rey Mysterio entered the ring to congratulate his son by placing the AAA Mega Championship around Dominik’s waist, symbolically passing the torch to the newer generation. However, the emotional moment quickly turned sour as Dominik berated Rey, dismissing him from the ring in a tense confrontation that highlights ongoing storyline friction between father and son.
This interaction adds a layer of complexity to Dominik’s character, showcasing his growing arrogance and desire to carve out his own legacy distinct from his legendary father. Wrestling observers anticipate that this dynamic will fuel future angles both backstage and on-screen[2].
What’s Next for Dominik Mysterio?
Balancing dual title reigns will pose challenges as Dominik is now obligated to represent both WWE and AAA commitments. Given his recent bravado—in which he declared himself the greatest WWE Intercontinental Champion ever—fans can expect Dominik to amplify his confidence and presence as a top-tier star.
As of now, speculation from wrestling pundits suggests a cross-promotional storyline could emerge, with Dominik perhaps championing AAA’s style within WWE programming and vice versa. This creative avenue opens doors for fresh rivalries and dream matchups, benefiting both promotions.
