Do we know what happened to Ghetsis's arm? I remember there was some discussion of it among fans back during Gen V, but I can't remember what came of it. His model in USUM just reminded me, because he has his other arm hidden. (Figured I'd ask you since I know you're pretty up on Gen V lore )
I'm confused by Gladion's whereabouts in the post-game. There is unused text about him training in Kanto and Johto, but the used version just mentions training (Wicke is the one that hands out Type: Null).
Lillie apparently stays in Alola for the island challenge. Boring.
Giovanni doesn't disband Team RR. What gives? Especially given his multiverse dominion goal.
So Marshadow possesses a bunch of Pokemon at an attempt to kill Ash and the other three trainers. Okay...
This makes me uncomfortable because it's another case of a movie treading close to my view of Neo Celebi, except... not really because there is no backstory to justify this extreme attitude. Plus, it's small in scale.
