El Hijo del Vikingo retained the AAA Mega Championship at Worlds Collide in a spectacular main event bought against WWE's Chad Gable.

It was a profile-raising performance from both men, but there’s some concern Vikingo may have suffered an injury during the closing stretch just as WWE is making him the face of AAA.

In April, WWE announced its acquisition of AAA in partnership with Mexico-based sports and entertainment holding company, Fillip. The companies will continue to work together in the months and years to come, including at the upcoming Triplemanía Regia on June 15, where TNA, WWE and AAA wrestlers will appear in the same show for the first time ever.
