WALTER made his WWE debut and confronted Pete Dunne to close NXT UK's first TakeOver special.
After defeating Joe Coffey to retain the WWE United Kingdom Championship in the main event of NXT UK TakeOver: Blackpool, Dunne was in the ring celebrating as the show appeared to be going off the air. But WALTER appeared in an angle at the end of the show, coming out to his regular theme music (Antonin Dvorak's Symphony No. 9). On commentary, Nigel McGuinness hyped that WALTER was here.
WALTER entered the ring to have a staredown with Dunne. Coffey got up from selling on the floor, tried to come into the ring, and WALTER booted him back down. WALTER and Dunne both posed at each other, with them going face-to-face and WALTER saying something to Dunne before leaving the ring.
It was confirmed this past November that WALTER had signed with WWE and would be coming to NXT UK. The 31-year-old Austrian is a star for wXw in Germany and is the current World Champion in PROGRESS Wrestling and OTT. He also held the PWG World title before dropping it in October.
