a question about sturdy and focus sash

Question

Say that a pokemon had sturdy an recover or any HP restoring move. What if you already got damaged and then he restored HP to full then got hit with a move that would KO the pokemon. Will that pokemon stay alive or faint since it was already damaged? Is it the same for focus sash too?

Answer 1

>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. Sturdy will activate as long as a Pokémon has full HP, and can therefore be used multiple times if brought back to full health. If a Pokémon with Sturdy is holding a Focus Sash, Sturdy will activate first. Final Gambit will KO a Pokémon with Sturdy even if its HP is full. -Bulbepedia

Sturdy will activate, as long as the Pokemon has full HP.
