You're not meant to know where he goes, he's really strange isn't he?
You just beat the Elite Four and obviously the Champion (Lance) again, go back to the same spot he was last time you fought him and beat him again. You can repeat this infinite times and each time he gets stronger until all his Pokemon are level 100 then that's it, it's the same battle every time you go back to fight him again - Same silence from him, same Pokemon used, same disappearance when you beat him.
(I really hate people like him who leave so many things unexplained, like where he goes, why he doesn't see his mum and why he never speaks [that could be because in earlier game he is main character -player- and like all players in Pokemon Trainer games he never speaks, and is muted, or because he is telepathic, or he has lost his voice, or because his lips have frozen over from training so long on a frozen mountain.)
Red once defeated walks away. You must defete elite 4 and if you do it at a certan type of day then he will be there once you beat lance again. If not don't worry he is at mt. Again. After you have killed red and elite 4 three (or five times if your unluckly ) professer Oak will have a letter for you. If he doesnt try prof elm. If you have a problem ask me. I have finished the game atleast 3 times over
Red is actually the name from Manga. US fans of the show watch the Anime and we know Red as Ash. The game allows you to choose who you know best. As for where Red goes. Through loads of game shark codes and such. As remains in the game script after and when you have beaten lance 4 times, Red will spawn at the same location using the same AI pokemon. They replicate those of the ones you aquire when playing the original pokemon Yellow. Consequently, beating Red does not make you pokemon Champion, it just allows you to roll the credits. The pokemon champion remains Red. The later games are in the future to the story line of Johto/Kanto, CGS, HHSS, and RBY which is noted to be 3 years before the current Johto set games. Also note, HHSS CGS, the base name for your sprite if not custom name is Ethan. For RBY, the base name is Ash and your rival is actually Silver.
After you beat him you can go to Mr. Pokemon and get Blue orb (if you have heart gold) or red orb (If you have Soul Silver). Then you can catch Groudon (Soul Silver) or Kyogure ( Heart Gold.) You take the Orb to the cave on Route 47 (I think, Some where in the 40's if not) and go to this tower. There you can catch Groudon/Kyogre. If you trade the pokemon you didn't get from someone else or you migrate it from Ruby/ Sapphire, You take both to the same place and you can fight Rayquazza.
Just a reminder: Groudon=Soul Silver Kyogre= Heart Gold Rayquazza= Either, just need Groudon AND Kyogre
If you don't feel like doing this and you have Kyogre, Rayquazza, and Groudon, you can just migrate them to Heart gold/Soul Silver. But you have to have Sapphire and Ruby. I would rather just get them from Soul Silver, more fun.
I don't know but I beat him by chance I think because I was in mount silver thinking I was looking for ho-oh and the I found him I beat him with a Lv.100 pikachu, Lv.63 Typhlosion and a whole heap of pokemon I was training in mount silver I can't remember which ones. But I am training for the second round of the elite 4 now
I beat red with just my mewtwo at lvl 75 knowing recover psychic flamethrower and water pulse and I didnt have to use anyone else no cheats cause I'm too poor to spend 20$ on a action replay or whatever I'm just that amazing with this game and now he is lvl. 100 and he now knows aura sphere instead of recover... F!!!! HP mwahahahaha
I don't know where red goes, I think what the other people said is true. But to get the Blue orb on Soul silver ,... You can't. You need kyrogre on soul silver by trading with somebody with kyrogre in heartgold. Once you show proffesor oak your groudon first, then you trade for kyrogre and then show him kyrogre. He will give you the jade orb to get raqayzaa..(or however you spell it, sorry) then you catch raqayzaa..
Red is really ash ketchum his from pallet tow he lives in the exact same house as ash does on pokemon silver and gold and he has all the pokemon that ash had on the first serious of pokemon just that there all high leveled and all at there top evolutions evolutions some
