silvally
A Pokémon from Pokémon Sun and Moon. It evolves from Type: Null and is associated with Gladion, who supposedly gave it its name.
Silvally possesses multiple forms, one of each type, accessed via the use of different Memories through its ability, RKS System. It is possible to distinguish which form of Silvally it is by observing its usually white feathers (characteristic of its Normal form) as they change color to match each type.
