'''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.
'''One-hit knockout moves''' (Japanese: '''{{tt|一撃必殺|いちげきひっさつ}}わざ''' ''one-hit knockout move''), commonly abbreviated as '''one-hit KO moves''' or '''OHKO moves''', are [[move]]s whose effect is to immediately drop the target's {{stat|HP}} to zero. When such a move successfully hits, the game will display the message "It's a one-hit KO!" (or simply "One-hit KO!" in Generation I).


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 OHKO moves have a base {{PP}} of 5. In [[Generation I]], their [[accuracy]] was a constant 30%, but they would automatically fail if the user's {{stat|Speed}} stat was lower than the target's. In later [[generation]]s, they instead automatically fail if the target is of a higher [[level]] than the user, and their accuracy starts at 30% and increases by 1% for each level the user is above the target. For example, if the user is 70 or more levels higher than the target, the move will have an accuracy of 100%.

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:

One-hit knockout moves (Japanese: 一撃必殺わざ one-hit knockout move), commonly abbreviated as one-hit KO moves or OHKO moves, are moves whose effect is to immediately drop the target's HP to zero. When such a move successfully hits, the game will display the message "It's a one-hit KO!" (or simply "One-hit KO!" in Generation I).

All OHKO moves have a base PP of 5. In Generation I, their accuracy was a constant 30%, but they would automatically fail if the user's Speed stat was lower than the target's. In later generations, they instead automatically fail if the target is of a higher level than the user, and their accuracy starts at 30% and increases by 1% for each level the user is above the target. For example, if the user is 70 or more levels higher than the target, the move will have an accuracy of 100%.

The accuracy of OHKO moves are fixed to the above formula, and will not be affected by Accuracy or Evasion stat stages. For example, holding a Wide Lens will not make OHKO moves any more likely to hit, and using Double Team will not make them any less likely to hit. However, any effects that cause a move to completely ignore the accuracy check (such as the Ability No Guard, or X Accuracy in Generation II or earlier) will allow OHKO moves to always hit.

A Pokémon with the Ability Sturdy will be unaffected by OHKO moves, unless that Ability is negated (such as through Mold Breaker or Gastro Acid). A Pokémon with Wonder Guard is also immune unless it is weak to the type of the OHKO move; this is the only functional difference when these moves are super effective. At full HP, a Pokémon holding a Focus Sash will instead be reduced to 1 HP by any OHKO move.

In the Pokémon Mystery Dungeon series of games, OHKO moves can hit regardless of level, although they are very prone to missing as always. When one hits, the game states that the target fainted through "calamitous damage" (changed to the standard "It's a one-hit KO!" in Gates to Infinity). However, they actually do 9999 damage, which can be seen when the attacks are reflected by IQ skills such as Counter Hitter if the Pokémon is revived by a Reviver Seed.
