This Pikachu looks ready for battle! Its yellow body is decorated with black stripes and it wears a red patch on its back. Its small mouth and long ears show its determination, and its brown eyes hint at its friendly nature. The two small red circles on its cheeks provide a unique look, but also serve as electricity storage for Pikachu to use against its opponents. I think this Pikachu would look best in a vibrant color palette of yellows, oranges, and reds. Give its fur texture and depth by adding shades of black, brown, and gray. For the stripes, use a bright yellow to create a dazzling contrast against the darker colors. Lastly, the cheeks should be accented with a splash of pink or orange to bring these elements together.
