During the Worlds Collide special event broadcasts through WWE Network, the NXT UK IMPERIUM Group (WALTER, Marcel Bartel, Fabian Aichner, and Alexander Wolfe) achieved a victory in tag team combat against The Undisputed Era (Adam Cole, Bobby Fish, Kyle O’Reilly, and Roderick Strong).
The confrontation was the main event of the day that faced the fighters of NXT and NXT UK. The meeting was normal in the first moments, but he was interrupted when Alexander Wolfe received an attack from Bobby Fish and Roderick Strong, which left him unconscious. The referee marked X with his arms and Wolfe was taken backstage to be treated.
The match continued with a disadvantage on the part of IMPERIUM, but both teams continued to dominate the match evenly. In the last moments of the contest, WALTER applied his golden bomb against Bobby Fish to obtain the victory of his team via pinfall.
Undisputed Era attacked IMPERIUM in TakeOver: Blackpool II
On January 12 in NXT UK TakeOver: Blackpool II, WALTER successfully defended the WWE UK Championship after defeating Joe Coffey in the main event. After the match, IMPERIUM appeared in full to celebrate the victory of WALTER. When the team assembled for the celebration, the members of The Undisputed Era made an appearance to attack the NXT UK group. A couple of weeks later, IMPERIUM would appear by surprise on the weekly show of the US development territory, attacking Undisputed. It was after Roderick Strong lost the American title to Keith Lee.
