Dominik Mysterio has added another major accolade to his career by winning the AAA Mega Championship in a dramatic main event at the WWE x AAA Worlds Collide event held in Las Vegas on September 12, 2025. Already the WWE Intercontinental Champion, Mysterio defeated El Hijo del Vikingo to become a double champion, showcasing his rising star power across North American wrestling promotions[1][2][3].
The highly anticipated AAA Mega Championship match was marked by intense back-and-forth action and interference that played a pivotal role in the outcome. During the bout, Finnish superstar Finn Balor, JD McDonagh, and the mysterious El Grande Americano got involved on Mysterio’s behalf, ultimately tipping the scales. At a crucial moment, as Vikingo attempted to unmask El Grande Americano, Americano stealthily handed a metal plate hidden inside a mask to Mysterio. Seizing the opportunity, Mysterio struck Vikingo with a frog splash onto the metal plate and secured the pinfall victory to claim the prestigious AAA Mega Title[1][4].
The match featured multiple high-impact moves including Vikingo’s signature 450 Splash and meteora attacks, as well as Mysterio’s classic 619 and Michinoku Driver. Despite Vikingo’s relentless offense and the crowd rallying behind him, the interference from Judgment Day faction members and El Grande Americano’s distraction proved decisive. After the match, WWE Hall of Famer Rey Mysterio made a proud but reluctant appearance to crown his son with the AAA Mega Championship belt, a moment loaded with generational significance given Rey’s legendary status and previous world titles[1][2].
This victory is historically significant as no member of the Mysterio family had previously held the AAA Mega Championship since the title’s inception in 2007—one year after Rey’s first WWE World Championship reign at WrestleMania 22. Dominik’s win marks a milestone moment that bridges WWE and Mexican wrestling’s rich traditions, revitalizing interest in this cross-promotion rivalry[5].
