Hello i would like to know Red's pokemon nature ... i heard you can use gameshark to catch them but if someone is already there can you please do it for me thanks!
Red's pokemon's nature are random. They don't have a set nature. This also goes with every other trainer.
I'm sorry to say that but they are not random in Blue's case... I've tested it on many games and well they always stay the same. So they surely are the same with Red.
