Magikarp is a reddish-orange, medium-sized fish. Its notable characteristics include large, heavy scales. Its fins are primarily white, but it has two stiff, three-peaked fins on its back and stomach which are both yellow. It also has long barbels.
Although this Pokémon is capable of surviving in even the most polluted ponds, it is usually overlooked by trainers because it is pathetically weak: even in the heat of battle it will do nothing but flop around. It is not a strong swimmer, and currents in the water will sweep it downstream. They are normally seen using Splash, which is unusual, as it makes them easy targets to predators. Before the species multiplied, it is believed that the ancestors of Magikarp were actually much stronger than the Magikarp seen today, and this belief has led scientists to research this species.
Long-lived Magikarp are able to utilize their immense splashing power to leap high enough to jump mountains. Eventually, they will evolve into Gyrados and KILL YOU ALL.
