One-hit knockout move
One-hit knockout moves, commonly abbreviated as one-hit KO moves or OHKO moves, are moves that, when used, cause the target's HP to drop to zero regardless of their stats. They are all highly inaccurate: given that their effect is to immediately make the target faint, to have them much more accurate would further encourage their use to quickly and easily finish battles.
All one-hit knockout moves have a base of 5 PP. In Generation I OHKO moves have a constant accuracy of 30%; however, the accuracy varies in subsequent generations, being at least 30% and increasing by 1% for every level the target is lower than the user. Therefore, a level difference of 70 will deliver an accuracy of 100%. It is not affected by changes in accuracy or evasion stats, and is calculated as follows:
Accuracy = ((User's level - Target's level) + 30)%
Pokémon with the Ability Sturdy are unaffected by them, unless the user has the Ability Mold Breaker or a variant of it. A Pokémon with Wonder Guard is also immune. At full HP, Pokémon holding a Focus Sash will instead be reduced to 1 HP by a OHKO move.
Any OHKO move will cause a Pokémon to instantly faint through 'calamitous damage'*, regardless of level, but they are prone to missing.
List of moves

- These moves are often combined with Lock-On or Mind Reader to ensure it hits. Articuno can learn Mind Reader and Sheer Cold, in Generation II Poliwrath can know Fissure and Mind Reader, and Smeargle can have any combination of the two types of move via Sketch.
- Lapras can learn the most one-hit KO moves of any Pokémon (excluding Smeargle), being able to learn Sheer Cold, Fissure, and Horn Drill.
- In Generation II, all one-hit KO moves were ineffective against one type of Pokémon. Guillotine and Horn Drill could not affect Ghost-type Pokémon unless Foresight was also used and Fissure could not affect Flying-type Pokémon. Sheer Cold (introduced in Generation III) broke this pattern, as no type is immune to Ice-type attacks.
