So John Cena vs Austin Theory was confirmed to be the opener for Night One.
Rey Mysterio vs. Dominik Mysterio
After enduring months of disrespect, Rey Mysterio will finally step in the squared circle in a highly-personal showdown against his own son, Dominik, at The Showcase of the Immortals.
When Dominik first emerged on the WWE scene, he was everything that would make a father proud. Together he and Rey proved to be an amazing tandem and soon became the first father-son combination to capture the SmackDown Tag Team Championship. Despite their success, however, Dominik soon began to feel stifled under Rey's guidance and it wasn't long before the up-and-coming Superstar did the unspeakable by turning on his dad.
After ripping himself away from his father and aligning with "Mami" Rhea Ripley and The Judgment Day, Dominik did not hesitate to unleash a constant mix of beatdowns and humiliation on his legendary father. He accused him of being a "deadbeat dad," crashed family holiday dinners with Ripley on his arm, cost Rey numerous matchups and even interrupted Rey's response after being announced as the newest member of the WWE Hall of Fame Class of 2023.
Despite Dominik's actions, the legendary Superstar never failed to do what was right, vehemently refusing to fight back or lay his hands on his son. But he could be pushed no further and, with a heavy heart, he reluctantly agreed to the contest to teach his son a lesson.
