After dealing damage, Bubble has a 10% chance of lowering the targetted pokemon's Speed by 1 step on the Stat growth scale.
Also, like all damaging moves that strike both opposing pokemon in a Double Battle, each individual pokemon takes 1/2 the damage they would if Bubble was used during a normal battle. This makes the attack's power effectively 10 during a Double Battle.
Bubble is affected by Brightpowder when the opposing pokémon is equipped with it.
