Rey Mysterio applied to trademark the “Prince Mysterio” name on Friday, March 15. The trademark was filed for merchandise use. This is the likely ring name for Rey’s son Dominic, who returned to WWE TV for a backstage segment with his dad on last night’s SmackDown. Dominic, who has been training for a pro wrestling career, revealed that he will be ringside at WrestleMania 35 for the match between Rey and WWE United States Champion Samoa Joe.
Back in November Rey filed to trademark the “Principe Mysterio” name, which translated to Prince Mysterio.
