Yawn (move)

Yawn makes the target drowsy. At the end of the next turn, the drowsy Pokémon will fall asleep, unless it is already afflicted by a non-volatile status condition. If a drowsy Pokémon switches out, it loses its drowsiness. Drowsiness cannot be passed by Baton Pass.

Yawn bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly.

Yawn will fail if the target is already afflicted by a major status condition or behind a substitute.

Yawn will fail if the target has the Ability Insomnia or Vital Spirit or if it has Leaf Guard during harsh sunlight; a drowsy Pokémon that has Insomnia, Vital Spirit, or (during harsh sunlight) Leaf Guard will not fall asleep. Yawn will fail if used on a Pokémon without Soundproof during an uproar. It will also fail when used on a target under the effect of Safeguard, but a Pokémon that is already drowsy can still fall asleep while under the effect of Safeguard.

If a Pokémon falls asleep from Yawn while it is in the semi-invulnerable turn of a move such as Dig or Fly, it will remain in that state until it attempts to use the move again (whether it wakes up or not).

Yawn can be used as part of a Pokémon Contest combination, causing Rest and Slack Off to have their base appeal points doubled.

Yawn no longer fails during an uproar, but drowsiness cannot cause a Pokémon to fall asleep during an uproar.

Yawn will fail if the target has the Ability Comatose or is a Meteor Form Minior; a drowsy Pokémon that has Comatose or that is Meteor Form Minior will not fall asleep. Yawn will fail if used on a target that is affected by Sweet Veil, Electric Terrain, or Flower Veil; Sweet Veil, Electric Terrain, and Misty Terrain each also prevent affected Pokémon already drowsy due to Yawn from falling asleep.

Yawn can also be used as part of a Contest Spectacular combination, causing certain moves (Dream Eater, Hex, Nightmare, and Wake-Up Slap) to give an extra three appeal points if used in the next turn.

If powered up by a Normalium Z into Z-Yawn, the user's Speed stat is raised by one stage.

In Red Rescue Team and Blue Rescue Team, and Explorers of Time, Darkness and Sky, Yawn is a move with 17PP that ignores accuracy and evasion checks. It targets enemy in front, inflicting Yawning status condition on them, causing them to fall asleep 3 turns later (if the target is in middle of a two-turn move such as Dig, it will be automatically brought of it when it falls asleep). This move fails if the target is immune to Sleep. This move is affected by Taunt, Magic Coat, and the Muzzled status condition.

In Pokémon GO, Yawn is a Fast Attack that has been available since December 8, 2017.
