Multistrike move
Multistrike moves are moves that strike an opponent more than one time in the same turn. Most multistrike moves will hit the opponent 25 times in a turn, but some work differently. Multistrike moves generally have low base power and imperfect accuracy to compensate for the fact that they hit multiple times. Bide and Counter only take the final hit of a multistrike move into consideration.
Effect
Generation I
If an opponent is knocked out by a multistrike move, the game does not state how many times the attack hit. Although only the first strike can be a critical hit, each successive one will deal the same amount of damage. Multistrike moves end instantly upon breaking a substitute. Bide and Counter deal damage based on the last strike alone.
Generation II
If the target faints, the number of strikes is shown afterward. Each strike has an independent chance of being a critical hit, as well as activating a King's Rock. If a multistrike move activates a target's Focus Band, no subsequent hits can knock it out.
Generation III
The number of hits is now shown before the target faints. A multistrike move may now continue attacking after breaking a substitute. Color Change will activate after the first hit of a multistrike move, possibly changing the type effectiveness of the remaining strikes.
Each strike from a contact multistrike move has an independent chance of activating a contact Ability. If Effect Spore causes the attacker to fall asleep, the move will end immediately.
Generation IV
If a multistrike move activates a target's Focus Sash, no subsequent hits can knock it out. Pokémon with Skill Link will always hit five times when using a 25 hit multistrike move. Each strike has an independent chance of activating a Razor Fang.
Generation V
The number of strikes is now shown after the target faints. If a Focus Sash, Focus Band, or Sturdy 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. Color Change now activates after the last hit of a multistrike move, so type effectiveness will not change during the attack. Each individual strike from a physical multistrike move will activate Weak Armor. Each individual strike from a Darktype multistrike move will activate Justified. Each individual strike from a contact multistrike move will activate a Rocky Helmet. Sap Sipper only activates once. Each strike has an independent chance of activating Stench, but this does not stack with the Razor Fang or King's Rock.
Generation VI
Spiky Shield and King's Shield only activate once. Parental Bond turns most singlestrike damaging moves into multistrike moves that hit twice per turn.
List of multistrike moves
25 strikes per turn
Most multistrike moves will hit an opponent two, three, four, or five times in one turn. These moves are more likely to hit two or three times, but will always hit five times when used by a Pokémon with Skill Link.


 Average power calculates the average total power from the move's power per hit and the average number of hits, ignoring the possibility of missing. Taking accuracy into account is as simple as multiplying average power by accuracy (modifiers to accuracy and evasion, including taking aim and No Guard, are not considered).
2 strikes per turn
Several multistrike moves hit an opponent exactly twice in one turn. For the most part, these moves are found on fewer Pokémon, several of them being signature moves, and generally have higher power than other multistrike moves, as they only hit twice. Moves affected by Parental Bond become this type of multistrike move.

3 strikes per turn
Triple Kick works differently than other multistrike moves. It can hit an opponent up to three times per turn, but its base power of 10 will increase by 10 with each subsequent hit, so its first, second, and third hits have powers of 10, 20, and 30, respectively. Also unlike other multistrike moves, each hit has its own accuracy check, and if one hit misses, the entire move ends.

 For Triple Kick, effective power is average power with all three accuracy checks taken into account (modifiers to accuracy and evasion, including taking aim and No Guard, are not considered).
Trivia
 Double Slap is the only multistrike move with "double" in its name that can hit 25 times.
 Triple Kick is the only multistrike move that powers up on each consecutive hit, and the only one in which subsequent hits can miss.
 From Generation IV onward, all multistrike moves are physical moves.
 Beat Up is the only move that can hit the target more than five times per turn.
