One-hit knockout move
One-hit knockout moves, commonly abbreviated as 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 Wonder Guard are unaffected by them, unless the user has the Ability Mold Breaker or a variant of it. A Pokémon with Sturdy 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
- Due to the presence of these moves, Articuno has been used in many battles, as it can also learn Mind Reader to make Sheer Cold sure to hit.
- Lapras can learn most of the one-hit knockout moves (Sheer Cold, Fissure, and Horn Drill), and is in fact second only to Smeargle, who can learn all four via Sketch.
- Before Generation III introduced Sheer Cold, all of these moves could not affect specific Pokémon. Guillotine and Horn Drill could not affect Ghost-type Pokémon, and Fissure could not affect Flying-type Pokémon.
