Barrage inflicts damage, hitting the target 2-5 times per use. There is a 37.5% chance that it will hit 2 times, a 37.5% chance that it will hit 3 times, a 12.5% chance that it will hit 4 times, and a 12.5% chance that it will hit 5 times. Provided that the move does not miss, it will hit 3 times on average, giving it an average power of 45. Although only the first strike can be a critical hit, each successive one will deal the same amount of damage.
Barrage will end immediately if it breaks a substitute. Bide and Counter will only acknowledge the last strike of this move.
All strikes now do damage independently, enabling any of them to be critical hits.
If the user is holding a King's Rock, the final strike has a chance to cause the opponent to flinch.
Generations III and IV
Barrage may now continue attacking after breaking a substitute.
There is now a ~33.3% chance that it will hit 2 times, a ~33.3% chance it will hit 3 times, a ~16.7% chance it will hit 4 times, and a ~16.7% chance it will hit 5 times. Provided that the move does not miss, it will hit ~3.167 times on average, giving it an average power of 47.5.
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 of the previous one.
If the target has Weak Armor, each strike will activate it.
Along with Kinesis and Struggle, Barrage is one of three moves introduced in Generation I that has yet to be featured in the main anime series. It is also the only move to be featured in Pokémon Origins but not in the main anime.
