I think it's time for a plot speculation thread.

For starters, this time we have a game that doesn't have an absolutely obvious main antagonist. Are Skull just a bunch of mid bosses who stop being relevant in the middle? Are Aether evil or just doing necessary evil to battle bigger thread? Do UBs have a grudge against Alola or it's just a wrong interpretation of their actions?
Are Lillie and Gladio siblings? What if Mohn who manages Poke Pelago is Lusamine's brother?
How much of Evangelion rip-off it's going to be?
