Gyarados #130 / 3281 Max CP

Once Gyarados goes on a rampage, its ferociously violent blood doesn't calm until it has burned everything down. There are records of this Pokémon's rampages lasting a whole month.

When Magikarp evolves into Gyarados, its brain cells undergo a structural transformation. It is said that this transformation is to blame for this Pokémon's wildly violent nature.
