if you own a Pokemon lets say magikarp the red areas on the map on the pokedex are where you can find it.
You catch Magikarp on route 12.
first put your magikarp on the top of the team then find a Pokemon then switch out your magikarp with a strong Pokemon then kill the Pokemon.
You can't, but you could get a magikarp by a guy on marvelous Bridge. You have to pay if you want the magikarp.
The more you have good pokeradar chains, the better you'll find one in wild while fishing. Or evolve a shiny Magikarp.

You have to find a shiny magikarp or a shiny gyarados. If you catch the magikarp, just evolve it. But catching a shiny Pokemon is EXTREMELY rare. Sorry to burst your bubble
magikarp
At level 20.
you can't, unless you find a job-request with magikarp as a client. It's recruitable in blue rescue team at the same place as feebas .
maybe a magikarp
Catch a shiny magikarp and evolve it.
you cant find a shiny magikarp that is the only Pokemon that cant be shiney i own every Pokemon that is shiny no normal legends and starters all them BUT NOT MAGIKARP
To get a red Gyarados in Pokemon LeafGreen you first need to catch a shiny Magikarp. This shiny Magikarp will be able to evolve into a red Gyarados. This is due to the red Gyarados simply being the shiny color of Gyarados.
