Raikou is a yellow tiger-like creature with black stripes that resemble lightning bolts and a white under-side. Raikou has a skinny, light-blue tail with an electric spark-shaped formation at the end. Raikou appears to have a grayish-purple cape that is supposedly made of thunderclouds. Most of Raikou's face is white with a light-blue "X" on its face and a grey crest on its forehead. Raikou has red eyes and long fangs in its upper jaws that make its appearance similar to the sabre-tooth cat.
