>>17929852I just realized how it works
X - original gimmick
X II - next guy given the gimmick by the office
X Jr. - smaller wrestler with the gimmick
Xito - mini wrestler with the gimmick
El Hijo del X - son with the same gimmick
So El Hijo Del X Jr. isn't X Jr. Jr., it's the son of the junior version of the X gimmick.
