Next, it showed off a Pokemon from Pokemon Sun called Passimian which is Fighting-type with the ability Receiver which takes the partner's ability when a partner faints.

Next is one in Pokemon Moon called Oranguru which is Normal/Psychic with Inner Focus and Telepathy. It has a new move called Instruct which allows the targeted Pokemon to use its last move instantly

Dartrix is extremely sensitive to other presences in the area and can detect opponents behind it and throw feathers to strike them without even seeing them. This Pokemon conceals sharp-bladed feathers inside its wings, showing astounding precision as it sends them flying in attack. And it goes beyond propelling its blade quills in simple straight lines - it can even bend these feathers to change their trajectories! Revealing a certain snobbiness in its personality, Dartrix cares a great deal about its appearance, grooming its feathers in every spare moment. In truth, it's also a bit of a birdbrain, with a tendency to bungle things up. Once it makes a mistake, it sometimes gets into a desperate struggle to gloss over the situation and ends up making a bigger mess than ever. At times, this Pokemon feels so bothered by its dirty or ruffled feathers that it can't focus on battle. When it loses its focus, it sometimes even retires from the battle on the spot! It's up to each Trainer to help Dartrix overcome this troublesome stage. If this Pokemon is with a Trainer who helps it through, its strength will grow hugely!

The bell-like object attached at the base of Torracat's neck is a flame sac, an organ that can produce flames. Torracat's emotions cause a rise in the organ's temperature, and when the organ spits flames, it rings with the high, clear sound of a bell. Torracat attacks using the flames emitted from this bell. Torracat's mane serves as an excellent sensory organ, and it can sense what's going on around it - even in the dark! It can also detect the presence of hidden enemies. Torracat has a great love for battle and will attack so relentlessly that its opponents lose the will to fight. And yet it sometimes behaves like spoiled child in front of Trainers or Pokemon with whom it has built a relationship of trust. The cat punch that this Pokemon can dish out with its strong forelegs is extremely powerful. It can bend iron bars and knock out large men with a single blow!

Brionne learns its dances by imitating the other members of its colony. It sometimes even learns dances from humans. This Pokemon is a hard worker and pours itself into its efforts until it has memorized each dance. As it dances, Brionne creates balloon after balloon. In battle, it first sends its opponent into disarray with its dancing, and then slaps its balloons into its target, causing the balloons to explode and deal damage. Brionne can dance in perfect time with others, even if they have only just met. On moonlit nights, you can sometimes see throngs of Brionne dancing as one, in perfect fluidity. Brionne always acts cheery and positive. Even when it's feeling sad, this Pokemon doesn't allow its sorrow to show. It's said that Brionne will only reveal a sad expression to a Pokemon or Trainer to whom it has opened its heart completely.

Ash-Greninja is obtained through a special demo to be released October 18th 2016. It can then be transferred to the main games at launch. Ash Greninja has the ability Battle Bond which causes it to change form when it knocks out an opponent.

Shinobi_Hime-Sama:
I got it on October 18th, as soon as it was out in the Nintendo eShop. I think I've done most of what you can do in the Sun and Moon demo, I did the Ten Carat hill Trial Quest, the Pokemon Catching contest, and the Mahalo Trail thing. I talked to the girl in the marina about her boat trip and the Beauty girl by the roadside, umm and that masala thing with Hau. Not sure what else there is to do in it.

-Pokemon Catching contest at Ten Carat Hill - catch at least 3 pokemon to get a Nugget.
-Fighting Pokemon Trainers at Ten Carat Hill - reward for beating them all is a Star Piece.
-Smashing rocks at Mahalo Trail, accessed via a woman at the end of one of the roads (this can be done over and over and the guy at the end will say something different up to about 5 times after which he starts repeating himself) - the first time you beat this you will get some Stardust.

-1 Day After Start - Speak to the man next to the Pokemon Center. He will give you 10 Pretty Wings.
-5 Days After Start - Speak to the girl in the southwest of Hau'oli City. She will introduced you to a character that helped her when she injured her ankle.
-12 Days After Start - Speak to a man in the City Hall. It is his Pikachu's birthday. Celebrate Pikachu's birthday with them, and he will give you a Balm Mushroom.
-18 Days After Start - Speak to the Police Officer in the Marina of Hau'oli City. He will request your help in apprehending some people.
-24 Days After Start - A girl in the port in the Marina of Hau'oli City is leaving Alola and needs support. Be with her as she leaves, and she will give you a Comet Shard.

-Lillie - On Fridays, you will find Lillie looking out at the sea near the Pokemon Center. She will speak to the Pokemon in her bag saying that she wishes she could share the view with it. She notices you and then walks off.
-Mother - On Tuesdays, you will find the player's mother exiting out of a shop.
-Alolan Dugtrio - In Ten Carat Hill, some days you will find a girl on the beach. Speak to her and she will enhance your PokeFinder and tell you about a Pokemon she's looking at. Zoom in and it's Alolan Dugtrio.
-Dexio & Sina - Sometimes, you will find Professor Sycamore's assistants Dexio & Sina in the Pokemon Center. They will explain about how they are on a vacation.
-Hau - On Sundays when the game is in night (game boots up at night randomly), you will find Hau in the Malasada Restaurant.

In the game, they are trying to create a league and the champions of the league take on the Battle Tree where trainers like Cynthia, Blue and Red are. They can be battled against and teamed with.
