How to catch Magikarp
Magikarp overall is a very difficult Pokemon to catch similar to the likes of Abra. Some common techniques for catching this Pokemon is paralyzing it with Thunder wave and using multi-hit moves like Doubleslap, Rock Blast (Geodude ), and Fury Swipes (Mankey ). Dragon Rage (Charmeleon ) can put Magikarp into the red.

However, make sure to also avoid using super-effective moves as Magikarp has very low health and will be most likely one-hit-killed, even if you use a regular attack.
