Mysterio faced fellow WWE alumnus Kurt Angle on March 20, 2016 for the upstart URFight promotion. Mysterio successfully defeated Angle in a two-falls match with assistance from rapper Riff Raff. In January 2017, Mysterio noted in an interview that he may consider opening up his own wrestling school. During the interview, he said: "I just thought I would never have the time. Now being able to make that time – to not have the busy schedule I had with WWE – gives me plenty of time to be a family man. I'm hoping that this time I'm spending with my son will open up that idea again and create a Rey Mysterio Wrestling school". On April 30, 2017, at the WCPW Pro Wrestling World Cup – Mexican Qualifying Round, Mysterio won the Mexico Leg with Penta El Zero M defeating Alberto El Patron in the semi-finals, and defeating longtime rival Juventud Guerrera in the finals. In Round 16, Mysterio lost to the English qualifier Will Ospreay.
