Sato

Sato and her siblings were the first beings in existence, and are considered the gods of the pokémon world. Sato takes the form of a ninetales and has three siblings; two more ninetales and one arcanine.

She and her siblings are responsible for creating Arceus, which began the creation of the universe. They monitor Earth's activities from a distance and are never supposed to intervene with mortals' lives, or else they risk disappearing.

Decades before the events of Stun, Sato's three siblings felt the consequences of meddling with the affairs of mortals after they disappeared and formed Tenebrae, almost causing the end of the world.

Sato sacrificed herself to become a part of Stun during the battle against Tenebrae.
