Gyarados is a large dragon Pokémon, resembling dragons seen in Chinese mythology. Its serpentine body is mostly blue, but its underbelly and the spots along its body are yellow. It has a three-pointed, dark blue crest on its head and four white fins down its back. Its mouth is very large and gaping, bearing four canine teeth, but bears some resemblance to that of its pre-evolution Magikarp. Like Magikarp, it has one barbel on both sides of its face. Its pectoral and dorsal fins also resemble Magikarp's. Gyarados is rarely shown with its mouth closed. When Gyarados is forced to undergo evolution, it retains Magikarp's red coloring, leading to the phenomena of the Red Gyarados. Its height is 21'04" and weight is 518.1 lbs.
A female has white barbels, while a male has blue. A Shiny male Gyarados will have red barbels.
Like most dragon-like Pokémon, Gyarados' strength is mostly Template:Stat, causing it to rely more on physical attacks than special. It is one of the few Template:Type Pokémon able to wield both Fire and Electric attacks. Its fangs can crush stones and its scales are harder than steel. Despite the strength of its fangs, it cannot learn the move Crunch and can only learn one of the elemental fang moves.
This Pokémon bears little resemblance to its docile pre-evolution. Gyarados is infamously known for its fierce temper and wanton destructive tendencies. Once it has worked itself into a frenzy, it will not calm until everything around it is destroyed; this tendency is attributed to the dramatic structural changes its brain undergoes during evolution. It seems attracted to violence. During times of human conflict, Gyarados are said to appear, burning entire cities down to the ground. In addition, Gyarados are also notoriously difficult to tame even after they are captured by the Trainer, usually requiring an exceptional amount of work in taming it until it can become loyal and obedient to its Trainer.
Gyarados usually live in large bodies of water, such as lakes and ponds or even seas and oceans. The Lake of Rage is the best known nesting area for Gyarados, and most famously, the red Gyarados, however, they are still quite rare even in the Lake of Rage, as they are seldom found in the wild.
