Its Adaptable Design Makes It Suitable For A Multitude Of Scenarios

Gyarados is a piscine, draconic Pokmon with a long serpentine 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 pair of barbel and a small white fin on each side of its face. The barbels are white on a female and blue 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.

The process of Evolution causes a change in its brain structure that is believed to cause its violent nature. Gyarados's fangs can crush stones and its scales are harder than steel. Gyarados is feared for its fierce temper and wanton destructive tendencies since ancient times. In some regions, Gyarados is called the "deity of destruction" because of this. It appears in times of conflict and destroys the surrounding area. Its rampages have been known to last a month at a time. These rampages can occur even during a harsh storm. A Gyarados's rage won't stop completely until everything is destroyed. Some believed any human settlement is fated to be destroyed should a Gyarados appear. Gyarados lives in both fresh and salty waters. Both Gyarados and its Mega form have demonstrated in Pokmon Chronicles and Pokmon the Series that it can leap huge distances both from the water and from the ground, usually several times its own body length. However, Gyarados is rarely seen in the wild. The move Hyper Beam is often associated with Gyarados due to it being being powerful enough to instantly destroy everything it hits.
