Gyro Ball is a Steel-type move with variable power and 100% accuracy. The power of Gyro Ball is dependent on the speed difference between the user and the target; it becomes stronger the slower the user is compared to the target. This move is particularly useful for slow Pokémon, as it can deal significant damage to faster opponents. Gyro Ball does not have a fixed power, making it unique compared to most moves, and it can be especially effective when used strategically in battles involving Pokémon with varying speed stats.
