The Pokémon will not lose HP due to recoil damage from its moves. It still takes recoil from Struggle.

If the Pokémon has full HP and takes damage from a move that would knock it out in one hit, it will endure the hit with 1 HP. The Pokémon is also immune to one-hit KO moves.

When the Pokémon takes damage from a physical move, its Defense stat is lowered by 1 stage, but its Speed stat is boosted by 2 stages.
