Item from pokemon-johto by
A single brilliant feather from Ho-Oh, the key to the Tin Tower's upper floors, and the sign that the rainbow phoenix is watching its watcher.
The Rainbow Wing is Ho-Oh's personal sign. A trainer who holds one has been chosen by Ho-Oh as worthy of the Tin Tower's upper floors. Ash received one, unknowing, when Ho-Oh flew over him on Route 1 on the first day of his journey. He has been carrying it pressed in the pages of his Pokédex case ever since. In the Johto saga, Morty recognizes it on sight, and a dawn at the Tin Tower's top floor — with the Rainbow Wing on the altar — is the saga's final quiet grace note.
A single long feather the length of a human forearm, plumage shifting between deep red, gold, forest-green, and violet as light moves across it. The quill is ivory and very slightly warm to the touch. Leaves an afterimage of rainbow light when held up to sun.
