A major title change took place at WWE x AAA Worlds Collide in Las Vegas on Friday night as Dominik Mysterio walked away with championship gold.

In the evening’s main event, Mysterio captured the AAA Mega Championship by defeating El Hijo del Vikingo. The victory did not come without controversy, as he had help from El Grande Americano along with his Judgment Day allies Finn Balor and JD McDonagh.
