Can you give me the link to the August 6 leak? I tried finding it online and cant find it.
It says all of the following:
Lillie and Gladion switch roles in the story.
Hau replaces Ilima as the first trial captain, specializing in Psychic-types.
Mimikyu's true form is Ghost/Dark. It may be activated by Disguise. It's ability causes all Pokemon who haven't attacked yet to instantly flinch.
Salazzle has a new male only "Gangster Form". It is Poison/Dark type and you receive it by leveling up a male Salandit while it knows the move Thief.
Alolan Quilfish is Poison/Steel type. It's ability makes it immune to all status conditions but makes it always move last.
Alolan Snubbull/Granbull are Ground and Ground/Fighting respectively. Snubbull has Intimidate. Granbull has a new ability that gives contact moves a chance to force the target to switch out.
Alolan Slugma/Magcargo are Ice types. Their ability reflects all Water-type moves back as powered up Ice-type moves however all Fire-type moves are guaranteed to burn it.
Z-Abilities are buffed up versions of normal abilities. Only Pokemon with signature Z-Moves (Pikachu, Cap Pikachu, A. Raichu, Eevee, Snorlax, Mew, Decidueye, Incineroar, Primarina, the Tapus, and Marshadow) can use them. Using a Z-Ability counts as a Z-Move. They halve all the Pokemon's stats at full HP, with stats getting higher the more damage they take.
