Early Bird (ability)

Early Bird (Japanese: はやおき Early Rising) is an Ability introduced in Generation III. Two Pokémon can have this Ability.

In battle
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.

Outside of battle
Early Bird has no effect outside of battle.
