Silvally

Sivally is a Normal-type Pokemon and the evolved form of Type: Null. It's ability is RKS System if you give it a memory disc to hold to change its type. Although its name was Type: Null at first, the boy who evolved it into this form gave it the name by which it is now known. Freed of the restraining effects of its mask, Silvally's senses are heightened, and it reverts to its natural temperament.
