| Pokedex Entries: |
| Red | In the distant past, it was somewhat stronger than the horribly weak descendants that exist today. |
| Blue |
| Yellow | Famous for being very unreliable. It can be found swimming in seas, lakes, rivers, and shallow puddles. |
| Gold | An underpowered, pathetic POKéMON. It may jump high on rare occasions, but never more than seven feet. |
| Silver | For no reason, it jumps and splashes about, making it easy for predators like PIDGEOTTO to catch if mid-jump. |
| Crystal | This weak and pathetic POKéMON gets easily pushed along rivers when there are strong currents. |
| Ruby | MAGIKARP is a pathetic excuse for a POKéMON that is only capable of flopping and splashing. This behavior prompted scientists to undertake research into it. |
| Sapphire | MAGIKARP is virtually useless in battle as it can only splash around. As a result, it is considered to be weak. However, it is actually a very hardy POKéMON that can survive in any body of water no matter how polluted it is. |
| Emerald | Its swimming muscles are weak, so it is easily washed away by currents. In places where water pools, you can see many MAGIKARP desposited there by the flow. |
| FireRed | It is virtually worthless in terms of both power and speed. It is the most weak and pathetic POKéMON in the world. |
| LeafGreen | In the distant past, it was somewhat stronger than the horribly weak descendants that exist today. |
| Diamond | It is said to be the world's weakest Pokemon. No one knows why it has managed to survive. |
| Pearl | It is unable to swim against even slow-moving currents. It always splashes about for some reason. |
| Stadium 1 | Whoever its opponent, and however horrible the attack it receives, all it does is SPLASH around. |
| Stadium 2 | An underpowered, pathetic POKéMON. It may jump high on rare occasions, but never more than seven feet. |
| TCG | Magikarp: Recent research has revealed the presence of dragon DNA in this species of Pokémon. |
