Reviving a thread for the old days, because I have a weird fascination with lineal championships.
Trusting some outside sources here, but currently the WWE, NXT, Universal and IC Lineal Championships are all unified with Brock Lesnar.
The Cruiserweight Lineal Championship currently belong to Pete Dunne. If you don’t use the 205 weight limit, it’s Johnny Gargano.
The U.S. and Tag Titles (the real ones, not the current “Smackdown” versions) would be a project and a half due to their lineage going back to the territory days.
