Arceus

Known as the Alpha Pokémon, this legendary deity first appeared in Arceus and the Jewel of Life. Driven by ancient resentment toward the people of Michina Town due to a past betrayal, the deity once threatened to annihilate the land. However, Ash and his companions traveled back in time to alter this tragic destiny, ultimately averting the catastrophe. Often referred to as "The Original One," its immense power is even reflected in the binding energy of the Red Chain.
