At WWE’s Worlds Collide event on September 12, 2025, Dominik Mysterio, affectionately known as “Dirty Dom,” captured the prestigious AAA Mega Championship by defeating the formidable El Hijo del Vikingo in a highly competitive 20-minute main event. This victory not only crowned Dominik as a double champion—retaining his WWE Intercontinental Title—but also underscored WWE’s strategic vision for the future of AAA wrestling under its growing influence[1][2].

Dominik’s Road to the AAA Mega Championship

The AAA Mega Championship is the top prize in Mexico’s premier Lucha Libre promotion, AAA (Asistencia Asesoría y Administración), a title steeped in rich history and regarded by fans as the ultimate symbol of excellence in Lucha Libre. Dominik Mysterio’s acquisition of this championship at Worlds Collide is significant for many reasons. First, it consolidates his standing as a rising star capable of carrying the legacy of the Mysterio family across multiple wrestling landscapes. Second, it signals WWE’s increasing integration of AAA talent and titles into its broader narrative fabric[1][6].

During the main event, Dominik faced El Hijo del Vikingo, a two-time AAA Mega Champion renowned for his athleticism and technical prowess. The bout featured moments of intense back-and-forth action, with Dominik leveraging both his technical skills and a controversial assist from senior AAA figure El Grande, which some insiders describe as the pivotal factor in his victory. The match’s conclusion saw Dominik pinning Vikingo to capture the championship, amidst a mixture of cheers and shock from the fans[2][4].

What ‘Dirty Dom’s’ Win Means for AAA’s Future

Sources close to WWE and AAA insiders reveal that Dominik’s win is part of a larger strategic blueprint aiming to reshape AAA into a global wrestling brand under WWE’s stewardship. An industry veteran familiar with backstage plans told Wrestling Headlines that “Dominik holding the Mega Championship is just the starting point. WWE sees AAA as more than just a partner; it’s a platform that will evolve, reflecting WWE’s values and storytelling priorities, while preserving AAA’s cultural essence”[Reference Summary].

This evolution envisions AAA as a complementary extension of WWE’s global footprint — one that embraces AAA’s lucha libre style and traditions but modernizes production values, expands international broadcast reach, and cross-promotes talent in WWE’s major shows like Raw, SmackDown, and NXT. The AAA Mega Championship, once predominantly defended in Mexico, is now destined for broader exposure with champions like Dominik Mysterio acting as ambassadors[1][6].

Backing from WWE Leadership and Industry Commentary

Following the event, WWE Hall of Famer Rey Mysterio took to social media and WWE.com to crown his son officially as the new AAA Mega Champion, symbolizing the passing of the torch not only within the family but arguably from AAA’s traditional era to its WWE-infused future[5]. WWE officials, in interviews with Fightful and podcast appearances, have echoed similar sentiments, emphasizing that Dominik represents a bridge between generations and styles.

A WWE insider confided in Ringside News, “Dominik’s dual championship status positions him uniquely to draw fans across cultures. It’s a calculated move to build intrigue around AAA’s product in the U.S. and worldwide, which benefits everyone involved — WWE, AAA, and the fans”[6].

Broader Implications for the Wrestling World

Dominik’s reign as AAA Mega Champion could usher in several significant trends:

• Cross-Promotion of Talent: Expect increased AAA talent appearances on WWE programming and vice versa, enhancing storyline complexity and global recognition.

• Expansion of the AAA Brand: Boosted marketing and broadcast partnerships will likely elevate AAA’s profile to new audiences beyond Mexico.

• Cultural Fusion: WWE’s production expertise combined with AAA’s unique lucha libre tradition could yield innovative wrestling styles and presentation.

Analysts also note that such consolidation matches WWE’s recent moves in acquiring or partnering deeply with other promotions like New Japan Pro Wrestling and Impact Wrestling, reflecting a broader strategy to dominate the global wrestling ecosystem by nurturing diverse, yet interconnected properties[Reference Summary].

Looking Ahead

While “Dirty Dom’s” triumph is an early step, it definitely foreshadows a transformative phase for AAA in the WWE era. Fans should anticipate more inter-promotional storylines, fresh rivalries, and the elevation of lucha libre iconography to international stages previously unimagined. As Dominik Mysterio holds the AAA Mega Championship belt, the wrestling world watches closely, ready for the exciting chapters in AAA’s ongoing evolution.
