Go to the safari zone and use a fishing rod. Once you catch a magricarp, max out it's
toughness condition. Then, boost it's attack using the carbos ( I think it is actually
something else). Then, raise it to level 70 by leaving it in the breeder. When you come
back, it will be red!!!

You catch a blue Magicarp... I think

u ****

if you head to eturna city after you beat elite four and go onto a bridge and fish alot
you will eventually find red gyrados its rare and probably the only one you'll eva see

I dont think there is a red gyarados

get action replay and put in the code for "shiny pokemon". Now you can get tons of red
gyrados!
