Nightmare (Japanese: あくむ Nightmare) is a non-damaging Ghost-type move introduced in Generation II. It is TM50 in Generation II.
Effect
 | This move effect may be in need of research. Reason: Does the Shed Skin bug occur in Pokémon Colosseum and XD? How does the Shed Skin bug work in link battles? You can discuss this on the talk page. |

Generation II
If the target is asleep, Nightmare afflicts the target with a status that causes it to take damage equal to one quarter of its maximum HP each turn. Nightmare inflicts damage after the afflicted Pokémon or its Trainer takes an action, unless its opponent faints (in which case Nightmare does not damage it that turn). If the Pokémon wakes up, the effect of Nightmare ends and does not reoccur if put back to sleep.
Nightmare bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of Dig or Fly.
In Generation II only, due to an oversight, if an opponent cures their Pokémon of sleep with a Full Heal or Full Restore, it will not be cured of Nightmare even after waking up; this does not occur if the player cures their own Pokémon of sleep.
Generation III
A Pokémon afflicted by Nightmare takes damage at the end of each turn (even if the opponent fainted).
In Pokémon Ruby and Sapphire only, due to an oversight, if a Pokémon cures itself of sleep with Shed Skin, it will not be cured of Nightmare even after waking up.
Nightmare can be used as the second move of a Pokémon Contest combination, with the user gaining 1 bonus appeal point if Hypnosis was used in the previous turn.
Generation IV to VII
Nightmare now has 100% accuracy.
Nightmare can be used as part of a Contest Spectacular combination, with the user gaining an extra three appeal points if a sleep-inducing status move (except Psycho Shift and Rest) was used in the prior turn.
If powered up by a Ghostium Z into Z-Nightmare, the user's Special Attack stat rises by one stage.
Generation VIII onwards
Nightmare cannot be selected in a battle.
