Hi all, I know all of you are awaiting the release of Ultra Sun/Ultra Moon- and possibly leaks/data mine, so here are some tidbits of the game!

There is another small Ultra Beast that is akin to Adhesive- both have an evolution, but possibly not how you expect. Codename is Fluidity. It is not obtainable post game.
On top of Fluidity, there are two more new Ultra Beast, with types not seen before
Giovanni is going to use Mega Mewtwo X if Moon, Y if Sun. You receive them after beating him.
Ghetsis has a new mega, but not who you might expect.
Poke Pelago is now upgraded to be more interactive with, suggest checking it out.
You will encounter Professor Rowan throughout the game, he will give you one of the Sinnoh Starters
There are 5 new Megas, and 3 new Z-Moves (not including those shown already- yes Mimikium is real)
Totem Pokemon can be used online, however they do not have the stat boosts
Alola forms do return, Alola Oddish is real, there are 4 more families that get Alola Forms, and 2 single stage.
Necrozma has a third new form.
Move Tutors will return, offering a plethora of options.
Ash Pikachu triggers an in game event depending on which one you have with you, each event only possible once.
