This September, Dominik Mysterio will get another chance to challenge for the AAA Mega Championship.
El Hijo del Vikingo will defend his Mega Championship against Dominik at WWE & Lucha Libre AAA’s next Worlds Collide special in Las Vegas. The one-on-one match was set up with Dominik issuing a challenge to Vikingo, saying the only reason Vikingo retained at Triplemania is because of AJ Styles’ interference.

AAA’s Triplemania event in Mexico City last weekend was headlined by Vikingo, Dominik, Dragon Lee, and El Grande Americano facing off in a four-way match for the Mega belt. Dominik appeared to have the title won after using a loaded mask as a weapon, but Styles pulled the referee out of the ring as Dominik was pinning Lee. He then took out Dominik with a Styles Clash, leading to Vikingo hitting a 630 and pinning Dominik for the win.
Vikingo is a two-time AAA Mega Champion, with his current reign beginning at the end of May when he won the title from Alberto El Patron.
The Worlds Collide event is being held in Las Vegas on Friday, September 12. It has a start time of 10 p.m. Eastern, meaning the show will begin right after that night’s SmackDown episode in Virginia ends.
After announcing its acquisition of AAA earlier this year, WWE presented a Worlds Collide event with the promotion in Los Angeles in June. That show aired live on YouTube, as did Triplemania this past weekend.
