The player must then talk to Xatu at the Great Canyon, who will explain what the player must do next. After defeating Entei at Fiery Field, Entei will turn the Clear Wing into the Red Wing (Japanese: しんくのはねCrimson Feather), and send the player to Lightning Field.
After defeating Raikou there, Raikou will turn the Red Wing into the Sunset Wing (Japanese: ゆうひのはねSunset Feather) and send the player to Northwind Field.
After defeating Suicune here, Suicune will turn the Sunset Wing into the Rainbow Wing (Japanese: なないろのはねPrismatic Feather) and send the player off to Mt. Faraway. Here, due to the power of the Rainbow Wing, the player can encounter, battle and recruitHo-Oh.
A Rainbow Wing played a major role in I Choose You!. Set in a timeline different from the main series, it was found by Ash when he first saw Ho-Oh. During the movie, Ash learned that Ho-Oh had given him the Rainbow Wing as a recognition of having chosen him to be the "Rainbow Hero", and decided to travel to Mount Tensei to meet and battle Ho-Oh.
Eventually, Cross, wanting to meet Ho-Oh himself, stole the Rainbow Wing from Ash and tried to use it to summon Ho-Oh. However, it instead became corrupted by his selfish desires, causing Marshadow to send a group of wild Pokémon on a rampage. When Ash was killed by the rampaging Pokémon, the Rainbow Wing crumbled away. However, once Ash was revived, the Rainbow Wing was also reformed, allowing Ash to use it to summon and battle Ho-Oh.
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.
