Flat stats across the board. Bashful sounds balanced, but in practice every Pokemon benefits from boosting at least one stat. Use a Mint to change to Adamant, Jolly, Modest, or Timid. Chansey Supply sells Nature Mints for 20,000 Poke Dollars. Swap off Bashful before you start climbing ranked.

Bashful is a neutral nature with no stat change. For special attackers, use Modest or Timid instead.

Bashful 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 Bashful Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Bashful nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse a Bashful Mint to change stat effects to Bashful. The original nature name stays but stats change. (Gen 8+)
What does the Bashful nature do in Pokemon?
Bashful leaves all stats untouched. No 10% boost, no 10% cut. It's one of five natures that have zero competitive impact.
Is Bashful nature good?
Honestly? Never, for competitive play. Some people argue a neutral nature works when a Pokemon uses all stats equally, but that scenario basically doesn't exist. Pick a stat to boost.
How do I get a Bashful nature Pokemon?
Wild Pokemon have a random nature, so you might get Bashful naturally. Synchronize and Everstone breeding also work. But the real question is why you'd want to keep it.
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.
