In Heart Gold and Soul Silver, go to the Lake of Rage, and talk to it. I recommend saving the game if you knock it out. Lower its HP to the red zone, and throw a Net Ball.
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)
to battle with the red gyarados you need surf and when you get to it talk to it..and gyarados is level 30 and very had to catch ,but, it will be your only oppertunity to catch one
He appears after you catch/kill the red gyarados
Catch the red one in the 'lake of rage' that's a shiny one. or use cheats.
A Magikarp can evolve into a red Gyarados. The Magikarp needs to be a shiny Magikarp in order for it to evolve into a red Gyarados. This is due to the red Gyarados simply being a shiny Gyarados.
You can catch red Gyarados anywhere because red Gyarados are only shiny but are extremely rare.
same chance to catch a shiny gyarados to catch eny shiny in platinum.
they dont have a red gyrados
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.
after you beat or catch the red gyarados he will drop a red scale
You have to catch or defeat the red GYARADOS
train it
In Pokemon Crystal version, you catch it at the Lake of Rage.
You have to go to the Lake of Rage. In the middle of the lake, there is a red gyarados. This is your only chance to catch the Red gyarados, so save before battling it to have multiple chances to catch it.
you are only able to catch red gyarados in Silver/Gold versions in Lake of Rage or something like that, my point is you can't catch it in Leaf Green/Fire Red
you aren't supposed to defeat the red gyarados, you're supposed to catch it
A red gyarados is just a shiny gyarados, it will still take time to accomplish.
