The trailer will release August 2nd. So at the begining it shows major changes
Story is not that changed, main changes(revealed in trailer):Gyms are back, first Gym Leader is Mallow Kiawe or Lana depending on Starter, Rowlet:Lana Litten:Mallow Popplio:Kiawe, I only have info on trailers, and I get them 3 weeks in advance so not every trailer at the mount but due to how samey the game seems from what I know, I wouldn't be suprised if a leader in the middle is the one that matches starter, and final or near end is super effective against your starter. It then shows Hau is still your rival, but his starter is Pichu, and he gets the starter strong against you later. It then teases that Hau has a "Secret" and shows a silhouette of Type: Null. It then shows Alolan Hoothoot. Alolan Hoothoot is Psychic/Flying. It has purple feathers and third yellow eye above its two red eyes. It wraps its wings in itself like a cloak. It gets Psychic Terrain highlighted as a new move in the trailer. It's Ability is Psychic Vision, if a Psychic Terrain is up, it's attacks never miss. They then show Alolan Wooper, Pure Electric. It's gills are now yellow and more zigzag like, and it is yellow with no tail. It's eyes are blue, no pupils. The trailer highlights Nuzzle as a new move. It's ability is Volt Absorb. They finish the Alolan Forms with Alolan Hoppip, Fire/Fairy. It's skin is purple with grey eyes, but the leafs are grey and burnt up, with smoke rising up. It is on the ground, and it's feet are much longer so it can stand. The trailer highlights Burn Up as a new move, and it's Ability is Solar Power. Continued below.
