Galloway made his debut for What Culture Pro Wrestling on 24 August 2016, at the "WCPW Stacked", defeating Doug Williams. He defeated Joseph Conners and Joe Hendry in a three-way cage match on 30 November to become the new WCPW Champion. Galloway retained the championship in defences with the likes of Hendry, Will Ospreay, Bully Ray and Joe Coffey on both the weekly "Loaded" show iPPV events. Following the announcement that Galloway had signed with NXT, a 30-man Rumble was announced for the WCPW World Championship with Galloway defending and entering at Number 1. Galloway would go on to be the 28th man eliminated from the rumble, ultimately losing the match and title to Martin Kirby on 29 April 2017. On 30 April, Galloway made his final appearance in WCPW at the Pro Wrestling World Cup Mexican Qualifying, losing to Cody Rhodes.
