Arceus

Arceus is known as “The Original One”, as it is said that it created Sinnoh and Ransei, and possibly the entire Pokémon universe, along with the lake guardians and creation trio.
Arceus is a white equine resembling a qilin or centaur with a dark gray, vertically-striated underside.The striated pattern has a similar recurrences on the underside of its mane, tail and face. Its four pointed feet are tipped with gold hooves. The long mane juts away from its face in gray, with green eyes and red pupils, as well as a green circular pattern below its eyes. Arceus also has a streak of gold coloration its head, and ears that point upward. Its neck is fairly long, with two pairs of extrusions on the sides. Arceus also has a golden cross-like wheel attached to its body by its round abdomen. The wheel also has four green jewels attached to it.
My coats design is mainly white, with exception for the collar, being dark gray just like the underside of Arceus. The reason why it's black is because the collar is “folded”, meaning you actually see the inside of the coat folded outwards, and since the underside of Arceus is mainly dark gray, and the fact that the part you'll see of the collar is actually the inside, the “under part” of the coat. There is a golden stripe around the waist with four spike-like stripes coming out form it vertically, representing the cross-like wheel attached to its body. The four green buttons of the coat being the four green jewels that are attached to Arceus wheel. Along the bottom of the coat there are kind of diamond-shaped, yellow stripes filled in with black, the yellow part and shape looking like the wheel around Arceus and the black filling it in to give of more detail. By the bottom of the sleeves there are a spiked, pointed triangular shape, representing the hooves of Arceus.
