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 that are both yellow. It also has long barbels.
A female has white barbels and a male has tan ones.
Long-lived Magikarp are able to utilize their immense splashing power to leap high enough to jump mountains. Magikarp also have a strong enough immune system to survive in the most polluted of waters.
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.
Magikarp is found in many bodies of water, such as lakes, rivers, and ponds. However, due to its weak swimming ability it usually lives downstream of the water's flow. Magikarp are extremely plentiful, living in almost any region.
This Pokémon was unavailable prior to Generation I.
