A Silver Wing in the anime
The Silver Wing appeared in several episodes in the Whirl Islands. In The Mystery is History, Luka rescues Silver from Cassidy and Butch and then explains that she's trying to discover information about a Silver Wing she got from her great-grandfather that she kept inside a locket. When Silver's parent appeared from the ocean, her Silver Wing began to glow a violent red. When it finally began to trust them and calmed down, the glowing stopped. When everyone goes swimming with Silver and its parent, she realizes the Silver Wing is a feather from Lugia, and is relieved to have finally unlocked its secret.
On Silver Rock Isle, there is a tale that a crew caught in a storm was rescued by a wild Lugia and from that day forward, the citizens on the island have glorified the Silver Wing, putting it on various trinkets, jewelry, souvenirs, etc.
Another Silver Wing appeared in Showdown At Linoone as one of the items Tokin picked up.
In Pokémon Generations
The Rainbow Wing made a brief appearance at the end of The Reawakening, where it was seen falling to the ground behind Eusine at the Burned Tower after his brief encounter with Suicune.

The Silver and Rainbow Wings in Pokémon Adventures
Green stole a Rainbow Wing and a Silver Wing from the Masked Man when she and Silver escaped from him. She later hid them on Yellow's straw hat. In the Gold, Silver & Crystal chapter, the artifacts were used to free Gold from the gap of time inside the Ilex Forest shrine where the Masked Man had trapped him in.
The Masked Man also used a Rainbow Wing and a Silver Wing directly collected from their respective Legendary Pokémon in order to create a GS Ball. Only a capture net created from these two feathers could contain Celebi and allow its holder to travel through time without suffering its negative side effects.
