"Something I seriously feel that is missing from USUM that should be in (SPOILERS)"

Giovanni brought all the previous team leaders, from their respective universes, who WON.So where the heck is the "Mother Beast Lusamine" from the original Sun and Moon who would have had no trainer to stop her? I mean, while I'm okay with how USUM turned out, I still miss the EPIC final battle with her fused with Nihilego. (Maybe even USUM Lusamine could have unique dialogue about it) via /r/pokemon http://ift.tt/2AfUTmY
