You either trade from soul silver or heart gold, use a action replay to make encounters shiny, catch a shiny magikarp legit(which might take a while)
you can catch a regular but i dont think red unless its a shiny
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
As far as I know, the red Gyarodos is never found. It was just a story to place the game in play. Without that, I'm sure your rival/best friend wouldn't want to search for a rare Pokemon in the local lake. They probably wouldn't even think about trying to find an amazing Pokemon in the lake. It would be exciting to capture a Red Gyarodos anyway. :)
there are two things you have to do disabandon team rocket and battle the red gyarodos
you get it at mr pokemons house after u give him the red scale from shiny gyarodos and going to mt silver and battling red which u do after getting all kanto and johto badges
yes you can but u must have magikarp which you have to unlock from a mission get it to lvl 21 then evolve it at luminous cave
After catching or defeating the red gyarodos lance will talk to you go to the house above the pokemon gym in mahogany town
Simply level it up to 20.
The noun 'catch' is a word to group any type of fish, for example:a catch of red fisha catch of trouta catch of catfish
Gyrados's shiny color is red so if you ever find a shiny gyrados or magikarp catch it. Also at the lake of rage you can catch one that is already red.
you need to catch a gold magikarp(shiny) by fishing or breeding then level it to 20. Or you can catch a red gyarados(shiny) by random. The chance to have it red are i in about 8000
you go to mahogany town and go to the lake of rage, after you catch and/defeat the red gyarodos, you meet lance who then askes for you cooperation to solve the problem with the mysterious signal comming from the store in mohagony town. you then have to do a series of events to shut down the signal. after that, team rocket takes over the radio tower in goldenrod city. when you beat that, you can to blackthorn city and fight claire, the last gym leader.
