This giant, skeletal Pokemon is a formidable sight with its red eyes, stubby tail, and three thick stripes on its head. Its lower body is an intense orange, while the rest of its body is a large, round shape. Its arms and legs are like thick reeds protruding from its base. To bring out its intimidating presence, I would suggest using bold colors, such as an intense red for its eyes and a deep orange for its body. Darker, more muted tones could be used for the background to give it an eerie feel that would match its spooky aesthetic. Although the stripes on its head may be difficult, you could try using a lighter color along the ridges of the stripes to create a gradient effect. This will make the Pokemon stand out while still keeping the aesthetic.
