In a thrilling main event at the WWE x AAA Worlds Collide event on Friday, Dominik Mysterio emerged victorious to become the new AAA Mega Champion, adding another title to his growing collection. The 28-year-old WWE Intercontinental Champion defeated El Hijo del Vikingo in a highly contested battle, with assistance from Judgment Day teammates and controversial outside interference playing a decisive role in his win[1][2][3].

The match, which was the highlight of the event held in Las Vegas, showcased an intense back-and-forth encounter between Dominik and Vikingo. After near falls and high-impact maneuvers from both competitors, the climax saw El Grande Americano, aligned with Dominik’s faction Judgment Day, unexpectedly intervene. As Vikingo attempted to unmask Americano, the masked luchador discreetly passed a hidden metal plate to Dominik. Seizing the opportunity, Dominik loaded the plate inside his mask and struck Vikingo with a devastating headbutt followed by a frog splash to secure the pinfall victory and claim the AAA Mega Championship[2][4].

Following the victory, WWE Hall of Famer Rey Mysterio entered the ring to ceremoniously place the championship belt around Dominik’s waist. However, the moment was far from heartwarming. Dominik brusquely ordered his father to put the belt on him and dismissively signaled Rey to leave the ring, reinforcing his “Dirty Dom” heel persona and signaling a testy father-son dynamic that continues to heat up within WWE storylines[3][4].

Dominik’s acquisition of the AAA Mega Championship significantly bolsters the dominance of Judgment Day across multiple brands and titles. The faction already holds the WWE Intercontinental Championship (Dominik’s possession), WWE World Tag Team Championships (Finn Balor & JD McDonagh), alongside the WWE Women’s Tag Team and Women’s World Championships earlier this year, making 2025 a banner year for the group’s championship reigns[1].

This new dual-champion status will likely require Dominik to balance his in-ring commitments across WWE’s American programming and AAA events in Mexico, a challenge he appears poised to meet given his rising profile and confidence in the ring. Already outspoken about being among the greatest Intercontinental Champions in recent WWE history, Mysterio is expected to carry the AAA Mega Championship with similarly brash confidence and swagger[1].
