Hello, I have news regarding the plot/storyline of Pokemon Sun & Moon.

First of all, The Aether Foundation are intact the true “villains” of the games, however they are more or less misguided.

Lusamine, Lillie and Gladden are infact siblings, however they went their seperate ways after Lusamine forcefully made Lillie be a test subject for her research on Ultra Beasts. Lusamine also indirectly had taken Type: Null from Gladion and passed it on to Wicke and Faba to do with as they please, this angered Gladion and when he went to take back Type: Null off of them he was shocked to learn that they had attempted to recreate the likes of a legendary pokemon, by splicing it with Popplio’s Final Evo, Rowlet’s Final Evo, Litten’s Final Evo as well as with Rockruff’s Final Evo.

Wicked and Faba are the true masterminds and villains of The Aether Foundation, and planned to use the Ultra Beasts to control Solgaleo/Lunala to then gain access to Marshadow.

There are 7 Ultra Beasts total, and yes they are capturable, but through unconventional means. You have the choice to choose which ultra beast you obtain, and you can only own two Ultra Beasts per copy of game, the one you choose, and Ultra Beast 7 which is obtained when Solgaleo and Lunala come together as one, it is a glass like scorpion chimera with the typing of Fairy/Dark. You obtain your chosen one during the climax of the main storyline.

Marshadow is the embodiment of complete void, not life, not death, not light, not darkness, completely void. Its typing is Psychic/Poison
