The Lunar Wing (Japanese: みかづきのはね Crescent Moon Feather) is a key item in Pokémon Diamond, Pearl, and Platinum, and Pokémon Black 2 and White 2.
In the games
In Pokémon Diamond, Pearl, and Platinum, it is found on Fullmoon Island—after receiving the National Pokédex—where Cresselia is floating above. The Pokémon will immediately flee the island, leaving behind the Lunar Wing. Once brought to Eldritch in Canalave City, it will awaken a young boy from his horrible endless nightmare.
In Pokémon Black 2 and White 2, the Lunar Wing can be found in the Strange House near Lentimas Town. If the Lunar Wing is taken to Marvelous Bridge, the player will be able to battle Cresselia.
| A feather that glows like the moon. It is said to possess the power to dispel nightmares.
In the anime
In The Rise of Darkrai, the Lunar Wing was sold to Dawn by a salesman who said that "it will make bad dreams a thing of the past."
The very same Lunar Wing appeared in Sleepless in Pre-Battle! where it was used to find the place where Cresselia resides.
