Now that legends is a new series, I just think it would be really neat if they revisited Alola and we got more lore and backstory about the ultra beasts + Z move phenomona + Ultra Necrozma

>Pokemon Legends Necrozma
>Ultra Beasts make a return
>More UBs discovered
>New Z crystals
>Ultra Necrozma fucks shit up
>Lusamine ancestor if we go past or descendant if we go future
>Another Tapu introduced (like genie in arceus)
>Alolan forms take shape of more mons living in the region once again (especially if set in the future)
>Ancient Trials if past, Advanced league if future
>Wormhole exploration instead of just linear pathing

So much more they could do with it!
