Why did my Eevee lose its Hidden Ability when it evolved?

Question

I got a hidden ability shiny Eevee from the GTS, and I evolved it into a Vaporeon. But, it lost it's hidden ability! Can someone please tell me why?

Answer 1

The only way a Pokémon can normally change its Ability is upon evolution. The "slot" storage system means that if an unevolved Pokémon has the "first" Ability for its species, it will have the "first" Ability of its evolved species upon reaching this stage, even if this Ability differs in the evolved species. In other words, a Poochyena with Run Away would evolve into a Mightyena with Intimidate, while a Poochyena with Quick Feet would evolve into a mightyena with quick feet

If you have the hidden ability, it will have the hidden ability upon evolution. If it has the first ability, it gets the first, if it has the second, it gets the second. However, it doesn't keep eevees anticipation, but it gets vaporeons hidden ability, hydration
hope I helped:D

Like dr dude said in his answer a Pokémon with it's Hidden Ability should still have the Hidden Ability of the Pokémon it evolves into.

Are you 100% sure your Eevee had Anticipation as it's Ability and not Adaptability or Run Away?

Anticipation is Eevee's Hidden Ability while Adaptability and Run Away are it's Normal Abilities. A lot of players often get Anticipation and Adaptability mixed up as to which is Eevee's Hidden Ability.

If your Eevee had Anticapation as it's Ability when evolved into a Vaporeon through the use of a Water Stone it would have it's Hidden Ability Hydration, while if Eevee had Adaptability or Run Away when it evolved into a Vaporeon it would have Water Absorb as it's Ability.

I'm not sure if it's even possible to change a Pokemon's ability, but it would either require cheats, glitches, or complicated steps. It can only change abilities through evolution, as far as I know.
