Kill or capture the red Gyarados at the Lake of Rage.
I Dont think so, sorry
It is not possible to get the Red Gyarados in Pokémon Yellow version. You can only get it in 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.
The Pokemon is : Unknown
the champion in gold and silver is lance. he has 3 dragonites, a charizard, a gyarados, and a aerodacty. against his aerodactyl and dragonites, you should use a strong ice Pokemon like lapris with ice beam. against his charizard and gyarados, use an ampharos with thunder punch.
If you are playing the original Gold game: You caught either a Missingno. (I'm pretty sure you didn't) or you caught the Red Gyarados. It's sad, but the Red Gyarados in Gold has a horrible glitch in it that has a chance of doing what you just described. If you are playing Heart Gold: I have no idea what happened. The Gyarados glitch does not occur in Heart Gold.
There is not a red Gyarados in Lake Verity. The in-game report of a sighting is simply a story mechanic to get the player there. This little story element is a reference to the Red Gyarados in the Lake of Rage on Pokemon Gold and Silver.
