Its trust in its partner is what awakens it. This Pokémon is capable of changing its type, a flexibility that is well displayed in battle.
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.
This is its form once it has awakened and evolved. Freed from its heavy mask, its speed is greatly increased.
Through the bond it formed with its Trainer, its will was strengthened, and it was able to destroy its control mask.
