Gyro Ball (Japanese: ジャイロボール Gyro Ball) is a damage-dealing Steel-type move introduced in Generation IV. It is:

Effect

Generations IV and V

Gyro Ball inflicts more damage the slower the user is compared to the target. Therefore, the larger the relative difference between the user's and target's Speed stat, the greater the damage. The base power is calculated by the following formula:

B a s e P o w e r = m i n ( 150 , 25 × C u r r e n t S p e e d t a r g e t C u r r e n t S p e e d u s e r + 1 ) {\displaystyle BasePower=min(150,{\dfrac {25\times CurrentSpeed_{target}}{CurrentSpeed_{user}}}+1)}

The Speed values used in the calculation take all modifiers into account (including stat stages, paralysis, held items such as the Iron Ball, and Abilities such as Slush Rush). Effects that only modify movement order without affecting Speed (such as Trick Room and Stall) have no effect on Gyro Ball.

If the user of Gyro Ball has a Speed stat that rounds down to 0, the stat will be treated as 1 in the power formula, to avoid having to divide by 0.

The maximum base power that can be reached with Gyro Ball is 150, if the target's Speed is at least 5.96 times the user's Speed.

Generation VI onwards

If the user of Gyro Ball has a Speed stat that rounds down to 0, the move's power is set to 1, entirely ignoring the above formula.

Pokémon with Bulletproof are immune to Gyro Ball.

In Gates to Infinity, the lower the user's Travel Speed is compared to the enemy's, the stronger the move. In Super Mystery Dungeon, the Speed stat is used for damage calculation instead.

Trivia

• In Pokémon Conquest, Gyro Ball will always do 1 damage if the user is faster than the target. This happens due to how the move's damage is calculated: the target's Speed stat is divided by the user's, and this quotient is rounded down to use as a damage multiplier. A faster user than the target will give a multiplier of 0, causing the move's damage to become 0, finally adjusted to a minimum of 1.
