From Bulbapedia, the community-driven Pokémon encyclopedia.

Belly Drum (Japanese: はらだいこ Belly Drum) is a non-damaging Normal-type move introduced in Generation II.

Effect

Belly Drum deducts half of the user's maximum HP (rounded down) from its current HP and, in return, it maximizes the user's Attack stat by raising it to +6 stages, even if the user's temporary Attack bonus stages were below 0 prior to using Belly Drum.

Belly Drum fails if the user's current HP is less than half its maximum, or if the user's Attack is already at +6 (even if the user has Contrary).

If the user has Contrary, its Attack will be lowered to -6 stages (although the message will still say that the user maximized its Attack); even if the user's Attack is already at -6 stages, Belly Drum will deduct HP.

In Generation II handheld games only, if the Pokémon is under 50% HP when using the move, it will still have its Attack raised 2 stages due to a bug.

Belly Drum can be used as the first move of a Pokémon Contest combination, causing Rest to score double the normal appeal if used in the next turn.

If powered up by a Normalium Z into Z-Belly Drum, the user restores all of its HP before Belly Drum's HP deduction takes effect.

In other games

Pokémon Mystery Dungeon series

Belly Drum maximizes the user's Attack. In the Rescue Team, Explorers and Adventure Squad series, the move cuts the user's Belly to 1, and will have no effect with a Belly of 1 or less. From Super Mystery Dungeon, it instead reduces the user's Belly by 50. If it is used when the user's Belly is 50 or less, it fails.

Trivia

  • Belly Drum is the only move that is capable of raising a single stat by more than three levels without Simple, not counting Haze, Psych Up, Power Swap, Guard Swap, Heart Swap, and Spectral Thief.
    • While Shell Smash causes a net total of eight stat changes, Belly Drum can cause more stat changes if the user has experienced at least a -3 stat change to its Attack stat, reaching twelve stat changes if the user has a -6 Attack stat change.
  • Due to how both this move and Darmanitan's Zen Mode Ability work, Belly Drum can force a Standard Mode Darmanitan to change its form (unless it is at full HP and has an odd maximum HP).
