Almost nobody uses Magikarp in battle. It exists to evolve into Gyarados, which is a completely different story. Get it there and you won't regret it. Known as the Fish Pokemon. Been around since Gen 1.
Magikarp's spread isn't flashy. Speed leads, Attack trails, 1 stats clear the bar. Easy to catch and worth 1 Speed EV, on a slow 1.25M XP grind.
A feeble, pitiful imbecile of a Pokémon that is nonetheless very hardy. Unperturbed by turbid water, it can be found living in all sorts of places.
Magikarp Weakness
GoodElectric and Grass-type moves hit Magikarp for super-effective damage. It resists 4 types, giving it decent defensive coverage. Magikarp's physical bulk (base 55 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
Magikarp evolves into Gyarados. It's a two-stage chain with the method shown below. A small partner pool for breeding via two egg groups. Eggs are hatches fast. The evolved forms gain up to 340 total stats over Magikarp.
How to Evolve
The special wall spread is where Magikarp earns its spot. Eviolite for a bulk boost that only works before full evolution, Careful nature for the right lean, and the moveset handles sustain. Swiftswim does the rest without needing a move slot.

Run Swift Swim on Magikarp. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Magikarp also gets Rattled, but they don't compare.
Magikarp fills the balanced role. It's a physical attacker with base 10 Attack. Base 80 Speed is workable — faster than some, slower than many. And it's fragile — can't afford to take many hits.
