However, there are moves that can significantly increase the chance of a one-hit KO under specific circumstances:
Moves that deal guaranteed critical hits:
* Fissure: This Ground-type move has a 30% chance of hitting a critical hit, which ignores the target's Defense stat.
* Sheer Cold: This Ice-type move has a 30% chance of hitting a critical hit, which ignores the target's Defense stat.
* Guillotine: This Normal-type move has a 30% chance of hitting a critical hit, which ignores the target's Defense stat.
* Horn Drill: This Bug-type move has a 30% chance of hitting a critical hit, which ignores the target's Defense stat.
Moves that deal massive damage:
* Explosion: This Normal-type move deals immense damage, but also eliminates the user.
* Self-Destruct: This Normal-type move deals immense damage, but also eliminates the user.
* Hyper Beam: This Normal-type move deals massive damage, but leaves the user unable to move for one turn.
* Draco Meteor: This Dragon-type move deals massive damage, but lowers the user's Special Attack stat by two stages.
Other factors that can increase the chance of a one-hit KO:
* Critical Hit Ratio: Certain Pokémon, abilities, and items can increase the chance of a critical hit.
* STAB: Same-Type Attack Bonus (STAB) grants a 1.5x damage multiplier when a move's type matches the Pokémon's type.
* Type Advantage: Pokémon take more damage from moves that are super effective against them.
Remember, even with moves that increase the chance of a one-hit KO, there's always a chance of the opponent surviving the attack. It's important to consider various factors like type effectiveness, stats, abilities, and held items before relying solely on one-hit KO moves.
