Arceus, known as the "Original One," is a Legendary Pokémon from Generation IV, celebrated for its role as the creator of the Pokémon universe. With a height of 3.2 meters and a weight of 320 kg, Arceus is often depicted as a majestic, horse-like figure adorned in a brilliant white hue. Its design features a halo-like ring around its body and four golden appendages resembling a wheel, symbolizing its divine nature and connection to creation.

According to Pokémon lore, Arceus emerged from an egg in a void and subsequently shaped the universe, bringing forth Legendary Pokémon such as Dialga, Palkia, and Giratina, each embodying fundamental aspects of reality—time, space, and antimatter. Arceus possesses the unique ability called Multitype, enabling it to change its type based on the Plate or Z-Crystal it holds, making it extraordinarily versatile in battles.

Arceus is often portrayed as a deity within the Pokémon mythos, representing balance and the cosmos. Its captivating design and profound lore have made it a central figure in many Pokémon games, manga, and movies, solidifying its status as one of the most iconic and revered Pokémon in the franchise.
