The Wishing Star (Japanese: ねがいぼしWishing Star) is a Key Item introduced in Generation VIII. It is a source of Dynamax energy, which can be fit into a Dynamax Band in order to allow a Trainer to Dynamax their Pokémon. According to Professor Magnolia, the Wishing Stars are parts of Eternatus, which is said to have some sort of connection to the Dynamax phenomenon.
During the post-game, Sonia is revealed to hold the Wishing Stars confiscated from Chairman Rose after his arrest at her laboratory. They're later stolen by Sordward and Shielbert with the help of Sonia's treacherous assistant in order to advance their plans.
Two Wishing Stars appeared in the Sword & Shield arc. One year before the events of the chapter, Shirudomiria and Sōdo had seen two Wishing Stars falling into the Slumbering Weald, and entered the forest to find them. With the help of Sōdo's Farfetch'd, they eventually found them, and, as thanks for the help, Shirudomiria had given one of them to Sōdo. They were later fit into Dynamax Bands for the two Trainers.
