You could either:
A. Trade one over from Heart Gold or Soul Silver (Find it in the Lake of Rage) or
B. Find a shiny Magikarp and evolve it
Actually there is no red Gyrados. I mean there is, but a red Gyrados is a shiny Gyrados.

yes
It exists only in Johto. Its just a shiny Gyrados. Fish for Gyrados, in 10, 000 tries you are sure to get one. That's how rare it is.
The answer's on my website: www.manaphy-star.webs.com All 6 steps...
to get a red gyrados you have 1% of finding a red gyrados and you have to use a super rod to find a red gyrados.
red gyrados is just shiney gyrados use the shiney code and find gyrados
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
The Red Gyrados drops it. If you already fought the Red Gyrados, you should already find it.
Gyrados's shiny color is red to get a red gyrados is very hard it takes 8000 chances or so to see it keep finding gyrados until its red.
you get a lvl 100 magicarp at the resort area, not a red gyrados
The red Gyrados is found in the Sendoff lake at the Spring Path.
