This mysterious Pokémon has an intimidating look, with its jet black body and menacing blood-red eyes. Its wide-open mouth reveals jagged teeth, while a red tongue hangs out below. Its hands have three extended claws on each, adding to the mysterious presence it emits. To color this Pokémon, I would go with a heavy contrast, with a strong indigo hue for the body, then a crimson red for the eyes, tongue, and claws. This will create a bold and vivid atmosphere that will make this image stand out. A lighter grey would be good for the edging, which will help draw all the colors together.
