A golden Margikarp is a shiny margikarp, and as with other shiny Pokemon, there is only a 1/1892 chance of getting a Shiny(golden) magikarp. Breeding a Shiny Gyarados or a Shiny margikarp with another shiny Pokemon THAT CAN BREED WITH GYARADOS/MARGIKARP may have a higher chance of breeding a shiny magikarp. You can also trade the shiny gyarados from Pokemon Gold, Silver, and Crystal version.
technically, yes. There is an 8462 to one chance of finding a shiny pokemon. If you found a shiny gyarados, it WOULD be red. You could also evolve a shiny magicarp(which, by the way, is gold). No, there is no guarantee on this, and there is no guaranteed chance of finding a red gyarados.
Yes, but like on gold/silver/crystal versions you have to find them randonmly. there are no gift shiny Pokemon like the red gyarados
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.
Your thinking of Pokemon Silver/Gold/Crystal, which has a Shiny Gyarados, which is part of the Plot, which you will have to fight at one point. Same for Soul Silver and Heart Gold, which also features a Red Gyarados.In Diamond/Pearl/Platinum, the only way you will encounter a Red Gyarados is in the wild. The chances are 1/8192 in finding a Shiny Pokemon. If you breed a Shiny Gyarados or Magikarp, and it has an egg, the egg has a 1/69 chance of being shiny.
its not a sure-fire thing. its totally random. the statistic for getting a shiny Pokemon is 1 in 8912 or basically 0.0122%. don't hold your breath for one. however, their is a shiny gyarados in the lake of rage outside of Mahogany town. that gyarados will always be shiny. its the only Pokemon in any game that is like that.
Red gyarados is actually a shiny pokemon so you would have to catch a shiny magicarp and evolve it in a shiny gyarados (meaning a Red gyarados)
Yes, the "Red Gyarados" is actually just a shiny Gyarados.
go to the lake of rage with surf and you see a red gyarados talk with him and you can cath a shiny gyarados
A red gyarados is a shiny gyarados (however, the Pokemon Company did not call them shiny untill the Unova Region). You can find it wherever you can find a normal gyarados, but your chances to find it are very slim.
there is no red gyarados. its just a shiny Pokemon and its red. not a huge thing
