When a Pokémon with this Ability is hit by a damage-dealing move (except Struggle and Shadow moves), Color Change will change the Pokémon's own type to the type of the move that it was hit by. Color Change does not activate if the Pokémon's substitute is hit.
Even if the Pokémon with Color Change has two types, it will only have a single type after the effect is applied. If a Pokémon with this Ability is hit by Weather Ball during shadowy aura, it will become Normal-type.
Color Change will activate after the last hit of a multi-strike move. Future Sight and Doom Desire activate Color Change when they hit (they do not activate Color Change when used).
Status conditions are inflicted before Color Change activates. As a result, even if Color Change would make the Pokémon become a type that is immune to the status condition, the Pokémon can still be afflicted with the status condition; for example, a Pokémon with Color Change that is hit by Poison Sting has a chance to be poisoned before it becomes Poison-type.
Color Change will not activate when the Pokémon is hit by a typeless Revelation Dancen.
Compound Eyes raises accuracy by 30% of a move's original accuracy in battles. This means that Thunder, for example, has 91% accuracy as opposed to the usual 70% (70 x 1.3 = 91%). A move with a theoretical accuracy of 77% or higher will have its accuracy set to 100% (77% x 1.3 = 100.1%).
Damp prevents all Pokémon from using Self-Destruct, Explosion, and Mind Blown; if a Pokémon attempts to use one of these moves, it will fail and the user will not faint or take damage. Additionally, Damp prevents the Ability Aftermath from doing damage when the Pokémon with Aftermath faints.
Damp affects non-adjacent Pokémon in Triple Battles.
Early Bird causes quick awakening from sleep. In the turn the Pokémon is put to sleep, the number of turns it will remain asleep is preset. If it is 6 turns, it will be halved to 3. If 3, it will be rounded to 1. If only 1 turn is preset, it is rounded to 0, causing the Pokémon to instantly wake up at the end of the same turn. This also applies to the self-induced sleep from Rest, reducing its length from 3 to 1 turn.
When a Pokémon with this Ability is hit by a move that makes contact, there is a 30% chance that the attacking Pokémon will become burned. If a Pokémon with this Ability is hit by a multi-strike move that makes contact (such as Fury Swipes), each hit has an independent chance to activate this Ability.
