Magikarp is a Water-type Pokémon introduced in Generation I.
It evolves into Gyarados starting at level 20.
Magikarp is a fishlike Pokémon with large, heavy reddish-orange scales. It has large, vacant eyes and pink lips. Its pectoral and tail fins are white. On its back is a stiff, three-peaked yellow fin, resembling a crown; there is an identical fin on its underside. It also has long barbels. The barbels are white on a female and pale-yellow on a male. A long-lived Magikarp is able to utilize its immense splashing power to leap high enough to scale mountains. It also has a strong enough immune system to survive in the most polluted of waters. However, it is usually overlooked by Trainers because of its perceived weakness: even in the heat of battle, it will do nothing but flop around. It is believed that the ancestors of Magikarp were actually much stronger than modern Magikarp, and this 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. It is normally seen using its former signature move, Splash, to leap out of the water, which makes it an easy target for predators such as Pidgeotto and Pidgeot.
