In mid-2019, Lee started to rise through the rank, and he quickly became a fan-favorite on The Black and Gold Brand.Lee's ascension reached a new level during the 2019 Survivor Series season, and he was the last man standing for Team NXT. He was ultimately eliminated by current WWE Universal Champion Roman Reigns.Early in 2020, Lee defeated Roderick Strong to become the NXT North American Champion, a title which he successfully defended against Dominik Dijakovic and Johnny Gargano.
