From Bulbapedia, the community-driven Pokémon encyclopedia.
This is a list of Pokémon that includes all Pokémon that can legitimately have their Hidden Abilities.
When breeding, if a female Pokémon with a Hidden Ability breeds with a male Pokémon in a compatible Egg Group, the offspring will have a 60% chance of also having the Hidden Ability; the Ability cannot be passed on if Ditto is a parent in this generation.
While Metapod, Flygon, Starly, and other similar Pokémon do not have a Hidden Ability that differs from the regular Ability, at least one of their evolutionary relatives do have one; therefore, they are included on this list. If only one gender is possible while the species itself can be either gender (as is the case of promotions), gender will be specified; the incapability of passing a Hidden Ability through breeding will be noted with an asterisk. Levels will also be specified if the Pokémon is obtainable at a level that is not level 10 if not obtained from a Hidden Grotto.
