No stat changes at all. Docile is one of five neutral natures, and competitive players avoid all of them. A nature that boosts Attack, Sp. Attack, or Speed will always outperform a flat stat line. Breed or use Synchronize to lock in a competitive nature instead of Docile.

Docile is a neutral nature with no stat change. For physical walls, use Bold or Impish instead.

Docile is a neutral nature — no stat is increased or decreased.
Competitive Role
No competitive advantage. A stat-boosting nature is almost always preferred.
How to Get
SynchronizeLead with a Docile Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Docile nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse a Docile Mint to change stat effects to Docile. The original nature name stays but stats change. (Gen 8+)
What does the Docile nature do in Pokemon?
Nothing, basically. Docile doesn't change any stat. There's no boost and no penalty. Your Pokemon keeps its base stat spread exactly as-is.
Is Docile nature good?
There's no competitive reason to keep Docile. A 10% stat boost from any other nature is free power you're leaving on the table. Nature Mints (Gen 8+) let you change it without breeding.
How do I get a Docile nature Pokemon?
Catch a Pokemon and check. There's a 4% chance of any specific nature, including Docile. Synchronize ability matches the lead Pokemon's nature to wild encounters (Gen 3+). Everstone passes a parent's nature during breeding.
When should you use a neutral nature?
Almost never. The only edge case is a Pokemon that uses physical moves, special moves, and needs every defensive stat and Speed. That Pokemon doesn't really exist in competitive. Even mixed attackers prefer Naive, Hasty, or another nature that at least boosts Speed.
