There's always the WWE Championship and then the other belt. The other belt floats around on the B-Show (and the B-Show is whichever show doesn't have the WWE Championship), and then the WWE Championship devours the other belt, ending its lineage forever. Then the WWE Championship reigns by itself for a short while until another other belt shows up, destined to eventually be devoured like all the others. Rest in peace WCW Championship, World Heavyweight Championship, Universal Championship, and eventually this new World Heavyweight Championship.
