In the Anime, Pokémon and People often fall asleep, though not always with an effect. The following lists only times when they fall asleep through an attack.


 * In Pokémon! I Choose You!, a Gengar uses Hypnosis put the opponent's Nidorino to sleep, forcing the Nidorino's trainer to switch.


 * In Challenge of the Samurai, Ash's Butterfree used Sleep Powder to calm a swarm of Beedrill. He later tried to use Sleep Powder on Misty's Staryu in The Water Flowers of Cerulean City, but Staryu avoided its effects by diving underwater.


 * In Hypno's Naptime, the abuse of Hypno's Hypnosis had been causing the Pokémon of HopHopHop Town to fall asleep without warning. It put the town's children, as well as Misty under a trance, in which they would run away to a pond and start acting like Pokémon.


 * In The Ninja Poké-Showdown, Koga's Venomoth used Sleep Powder on Ash's Pidgeotto during their gym battle, forcing Ash to switch.


 * A Jigglypuff that followed Ash and his friends almost always used Sing whenever it appeared. When it discovered that its "audience" slept through it song, the balloon Pokémon doodled on the sleeping Pokémon, and people, before leaving in a huff. However, its songs have still helped out Ash and the people he has met from time to time. In its debut episode, its song helped the cranky people of Neon Town finally fall asleep, after which, they woke up much more agreeable and friendly. In the following episode, Jigglypuff's song was able to put back to sleep the angry ancient Pokémon that slept there.

In The Rise of Darkrai, Darkrai used its Dark Void in order to warn the people of Alamos Town about the coming attack of Dialga and Palkia. Unfortunately, the Bad Dreams that it caused led Baron Alberto to see Darkrai as a threat. In League Unleashed!, Nando's Kricketune used Sing to put Ash's Heracross to sleep. However, Heracross was able to counter it with Sleep Talk.
 * In Friend and Foe Alike, Ritchie's Butterfree, Happy, used Sleep Powder on Ash's Squirtle during their league battle. Squirtle, already tired from a previous attack by Jessie, James, and Meowth, was declared unable to battle.


 * In The Semi-Final Frontier!, Tobias's Darkrai used a combination of Dark Void and Dream Eater against Ash's Heracross, quickly knocking it out. Darkrai also put Sceptile to sleep, but it managed to wake up just in time to take it out with Leaf Blade.
