View source for 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.

When used, they will always fail if the level of the target is higher than the level of the user, except in [[Generation I]], where they would fail if the user's {{stat|Speed}} stat was lower than the target's.

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 {{a|Wonder Guard}} are unaffected by them, unless the user has the Ability {{a|Mold Breaker}} or a variant of it. A Pokémon with {{a|Sturdy}} is also immune. At full HP, Pokémon holding a [[Focus Sash]] will instead be reduced to 1 HP by a OHKO move.

==Trivia==
* Due to the presence of these moves, {{p|Articuno}} has been used in many battles, as it can also learn {{m|Mind Reader}} to make {{m|Sheer Cold}} sure to hit.
** The same was true of a {{p|Poliwrath}} traded forward from [[Generation I]] that had learned {{m|Fissure}}, and could learn Mind Reader in [[Generation II]].
*** Also, {{p|Smeargle}} is used in the same way, due to its ability to learn any move via {{m|Sketch}}.
* {{p|Lapras}} can learn most of the one-hit knockout moves ({{m|Sheer Cold}}, {{m|Fissure}}, and {{m|Horn Drill}}), and is in fact second only to Smeargle, who can learn all four via {{m|Sketch}}.
* Before Generation III introduced Sheer Cold, all of these moves could not affect specific Pokémon. {{m|Guillotine}} and {{m|Horn Drill}} could not affect {{type|Ghost}} Pokémon, and {{m|Fissure}} could not affect {{type|Flying}} Pokémon.
