On Smogon's Movedex: Generation IX

Population Bomb (Japanese: ネズミざん Proliferation) is a damage-dealing Normal-type multistrike move introduced in Generation IX. It is the signature move of Tandemaus and Maushold.

Effect

Population Bomb inflicts damage, hitting the target up to ten times per use. Each of Population Bomb's strikes has a separate accuracy check. If any strike fails, the move ends.

If the user is holding Loaded Dice, only one accuracy check is performed, and it will hit between four and ten times (with an even chance of each number of hits). If the user has Skill Link, the move will have only one accuracy check and hit the maximum ten times.

If used by a Pokémon with Sharpness, its power is increased by 50%.

If the target has an Ability that activates upon contact, each strike counts individually, enabling the Ability to activate multiple times. If the target is holding a Rocky Helmet, the user is damaged for each strike. If a Focus Sash activates before the last strike is dealt, the following strike will cause the defending Pokémon to faint. A Focus Band can still activate repeatedly to prevent fainting, but each chance is independent. Sturdy will activate with each hit if the defending Pokémon has a maximum HP of 1.

Calculations

Assuming no modifications to accuracy or evasion, this move's average effective power is ~117.24, and the chances of it hitting a certain amount of times are as follows:

Trivia

• Along with Triple Kick and Triple Axel, Population Bomb is one of only three multistrike moves whose chances to miss for successive hits are independent of the first hit.
• The Japanese name for the move can be read as both ねずみ算 nezumizan (to multiply like mice; literally "mouse mathematics", a common arithmetic problem) and ねずみ斬 nezumizan (mouse cut), explaining why the move is strengthened by Sharpness.
