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

Worlds Collide 2025 kicked off WWE's partnership with AAA properly as El Hijo del Vikingo bested Chad Gable for the AAA Mega Championship in a thrilling affair.

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.
