Insomnia (Japanese: ふみん Insomnia) is an Ability introduced in Generation III.

Effect

In battle

Insomnia prevents the Pokémon from being afflicted by sleep and Yawn. Rest will fail when used by the Pokémon.

A Pokémon with this Ability will wake up if it is asleep in battle (such as if it gains the Ability outside of battle or by an effect like Skill Swap, or is put to sleep by a Pokémon with an Ability like Mold Breaker).

If a Pokémon with this Ability is drowsy due to Yawn, when it would fall asleep the Ability activates and keeps it awake.

The move Worry Seed can change the target Pokémon's Ability to Insomnia.

Generation III

If a sleeping Pokémon with Insomnia is sent into battle as one of the lead Pokémon or to replace a fainted Pokémon, or gains Insomnia due to Trace, it will not be cured of sleep until after a Pokémon takes its turn (uses a move, switches out, etc.). It will be cured of sleep if it is switched in to replace a switched out Pokémon (including if switched in via Baton Pass).

If a sleeping Pokémon has Insomnia as its original Ability but not its current Ability, it will remain asleep when switched out.

If the Pokémon with this Ability is asleep and is holding a Chesto or Lum Berry, Insomnia will cure the Pokémon of sleep before the Berry has a chance to be consumed.

Generation IV

There is no known way for a sleeping Pokémon with Insomnia to enter battle.

If a sleeping Pokémon has Insomnia as its original Ability but not its current Ability, if it is one of the active Pokémon at the end of the battle or switched out, it will be cured of sleep (with no message).

Generation V onward

When a sleeping Pokémon with Insomnia enters battle, it will be cured of sleep.

If a sleeping Pokémon has Insomnia as its original Ability but not its current Ability, it will remain asleep when switched out.

If the Pokémon with this Ability is asleep and is holding a Chesto or Lum Berry, the Berry will be eaten and cure the Pokémon of sleep before Insomnia has a chance to activate.

Outside of battle

If a sleeping Pokémon gains Insomnia by evolution or the Ability Capsule, it will not wake up until sent into battle. Pokémon with Insomnia will not be put to sleep by the Gentleman's Kirlia in the Battle Pike nor the Battle Arcade's game board.
