The Gold Magikarp is a shiny Magikarp. It evolves into a red Gyarados.
There is a 1 in 8912 chance that the Pokemon you encounter is shiny. This can be reduced to 1 in 2048 chance by using the Masuda method. This is basically when you breed a Magikarp with a foreign Ditto. The egg has a 1 in 2048 chance of being shiny.
It's a level 100 Magikarp.
