Dominik Mysterio, currently reigning as WWE Intercontinental Champion and AAA Mega Champion, is set to appear in a special segment at the AAA Alianzas event in Mexico City on September 27, 2025, marking his growing presence in both WWE and Mexico’s premier wrestling promotion, Lucha Libre AAA Worldwide (AAA).

Known in WWE as the “Dirty” Double-Champ for holding two prestigious titles simultaneously, Dominik’s unique position as a cross-promotional champion underscores his rising star power and deepening ties to his Mexican wrestling heritage[1][4].

Dominik Mysterio’s Historic Double Championship Reign

Dominik Mysterio, real name Dominik Óscar Gutiérrez and the son of WWE legend Rey Mysterio, has cemented his place as one of WWE’s top stars. His current Intercontinental Championship reign began at WrestleMania 41 after defeating Finn Balor, Penta, and Bron Breakker in a high-profile match, marking a major milestone in his career[1].

Shortly after, Dominik became the AAA Mega Champion by defeating El Hijo del Vikingo at the Worlds Collide: Las Vegas event. This win made him the first wrestler to simultaneously hold the WWE Intercontinental and AAA Mega Championships, a historic achievement showcasing his versatility and appeal on an international scale[1][4].

The Demands of Being “Dirty” Double-Champ

Sources close to WWE reveal that maintaining two championship titles has been an intense challenge for Dominik, who frequently travels between the United States and Mexico to fulfill his commitments. His schedule involves regular appearances on WWE Raw, occasional spots on SmackDown, and participation in televised premium live events alongside his AAA responsibilities[1].

A WWE insider told Fightful that “Dominik is embracing the pressure of being the face of both promotions, often juggling back-to-back appearances with little downtime.” This heavy workload is a testament to his dedication and resilience as a young performer navigating a demanding dual role.

Upcoming AAA Alianzas Segment

The upcoming AAA Alianzas event on September 27 in Mexico City is anticipated to be a major highlight for Dominik. The special segment he is scheduled to participate in will likely spotlight his dual championship status and further strengthen the bond between WWE and AAA, two of the world’s largest wrestling organizations.

According to WWE.com sources and veteran wrestling analyst reports, this promotional crossover event reflects WWE’s strategy to boost international collaboration and embrace the Mexican wrestling fanbase, where Dominik’s family legacy and current success resonate deeply[1][4].

Recent WWE Milestones and Reactions

Dominik’s Intercontinental Championship was most recently on display at SummerSlam 2025, where he successfully defended the title against AJ Styles in a match praised for its storytelling and homage to wrestling legends[2][3]. His victory featured a memorable callback to classic WWE moments, enhancing his reputation as a savvy and respectful performer.

Liv Morgan, a fellow WWE wrestler and rumored close associate, publicly hailed Dominik as “the greatest WWE Intercontinental Champion in history” via social media shortly after his SummerSlam win, highlighting the peer recognition he is gaining within WWE circles[3].

Backstage Buzz and Future Prospects

Backstage sources reveal that Dominik’s involvement with AAA Alianzas is not just a one-off appearance but could pave the way for more frequent cross-promotional appearances, potentially leading to storyline opportunities that span the WWE-AAA partnership.

A WWE producer noted on a recent wrestling podcast, “Dominik is more than a champion; he’s a bridge between wrestling cultures. The Mexico City segment will likely be a springboard for exciting angles that benefit both brands.”

Fans and analysts are keenly watching how Dominik’s character evolves within WWE’s Judgment Day stable and across AAA’s storylines. Balancing his duties while maintaining championship credibility in both promotions will be key to his continued rise.

Dominik Mysterio’s Legacy and Impact

As a third-generation wrestler, Dominik leverages the rich heritage of the Mysterio family, aligning with the legacy of his father Rey Mysterio—the only other Mysterio to capture the WWE Intercontinental Championship—and his great-uncle Rey Misterio Sr.[1]. Holding two major titles simultaneously at just 28 years old puts Dominik in rare company and signals a promising future in professional wrestling.

His success in both WWE and AAA is also emblematic of the increasingly global nature of professional wrestling, where talent frequently crosses traditional promotion boundaries to engage broader audiences.

What to Expect at AAA Alianzas

The special segment at AAA Alianzas will likely feature Dominik addressing the crowd as a dual champion, possibly including a face-to-face confrontation or alliance formation with top AAA stars. Fans can expect a mix of high drama, emotional connection to Dominik’s Mexican roots, and potentially explosive storyline developments.

Wrestling experts speculate that this event could reveal new dimensions of Dominik’s character, blending his WWE heel persona as a “Dirty” champion with the passionate reverence Mexican fans have for the Mysterio family name.

With two heavyweight championships across the wrestling landscape, Dominik Mysterio’s special appearance at AAA Alianzas promises to be a pivotal moment for his career and an exciting spectacle for fans on both sides of the border. As the wrestling world watches closely, Dominik stands poised to solidify his place as a groundbreaking star of the modern wrestling era.
