no one knows but you can battle him again if you beat the elite four again.
you get it from prof. Oak after you beat red on mt. silver.
Go to Kanto, beat the gyms, go to Mt Silver and beat Red.
At the top of Mt. Silver. He is extremely strong, bring your best team
every time you beat the Elite four, red will appear at the top of Mt. Silver again
Beat the elite four again then go back to the top of mt. Silver
somewhere....... to defeat him again, you have to beat the elite 4 and he will be back in mt. silver again.
Blue is the viridian gym leader and red is on top of mt silver once you beat all the kanto gyms
on the peak of mt silver
yes you can that guy is super wrong what an a**hole you can beat the Pokemon league again and then go back to mt.silver and red will be there!
beat the elite 4 again then go back to Mt Silver
He is still there.
I do believe Red goes to Sinnoh. After you beat Round 2 of the Elite Four, however, he'll re-appear at Mt. Silver and you can battle him again. However, with every battle you have with him, his Pokemon get one level higher.
