From Bulbapedia, the community-driven Pokémon encyclopedia.
Sturdy (Japanese: がんじょう Sturdy) is an Ability introduced in Generation III. Thirty-five Pokémon can have this Ability.
Generations III and IV
Sturdy negates one-hit knockout moves.
In addition to Sturdy's previous effect, Sturdy now works like a Focus Sash, causing the Pokémon to have 1 HP remaining if an attack's hit would have brought it from full health to 0 HP (including confusion damage). Sturdy will activate as long as a Pokémon has full HP, and can therefore be used multiple times if brought back to full health, or if the Pokémon has a maximum of 1 HP.
If a Pokémon with Sturdy is holding a Focus Sash, Sturdy will activate first. If a Pokémon with Sturdy uses a move that causes the user to faint, such as Explosion or Final Gambit, it will still faint. It does not protect the Pokémon with Sturdy from knocking itself out with recoil damage. Destiny Bond and Perish Song can still cause a Pokémon with Sturdy to faint.
When a multi-strike move hits a Pokémon with Sturdy, Sturdy's effect activates only for hits while the user has full HP, so hits after the first one can potentially KO the Sturdy Pokémon.
Outside of battle
Sturdy has no effect outside of battle.
