Gyarados is a serpentine Pokémon with a long body covered in slightly overlapping scales. It is mostly blue with a yellow underbelly, and it has a row of yellow spots down each side. Its mouth is very large and gaping, bearing four pointed teeth and yellow lips. It has one barbel and a small white fin on each side of its face. The barbels are white on a female and tan on a male. It has small, red eyes, a three-pointed, dark blue crest on its head, and four white, spiky dorsal fins. Gyarados's tail fin is similar in structure to the crest on its head, except with a thin, white fin spread between the points.
