6 stables WWE should introduce Six-Man Tag Team titles for

# 2 Undisputed Era (WWE NXT)

The Undisputed Era has been the most dominant faction in NXT history with all members holding titles during 2019/2020, but have since lost all their titles

Much like Imperium, the four-man Undisputed Era is strong enough to support a main champion in Adam Cole, while competing for a secondary Trios Championship in WWE.

In 2019/2020, every member in the Undisputed Era held a title at the same time. Adam Cole held the NXT Championship, Roderick Strong held the NXT North American title, while Bobby Fish and Kyle O'Reilly held the NXT Tag Team titles.

While Cole is still challenging to regain the NXT title again, Strong, O'Reilly and Fish aren't a part of any title pictures at the moment, having lost the NXT North American and Tag Team titles earlier in 2020.

The Undisputed Era would be another great team to introduce the first ever WWE or NXT Six-Man titles. Adam Cole participated in the Ring of Honor tournament to crown the first ever Six-Man Champions as a part of Bullet Club, but they lost in the first round.
