Nothing much. Alot of backstory, sich as the battle frontier, and filling up your pokedex etc etc etc
Nothing.thats it
With Pokemon.
Nothing...I think you might be able to obtain Kyogre but I don't recall anything else :)
You finish Pokemon heart gold after you beat red.
They are still in the Pokemon league
Yes.
You Have To beat Red First.
go to prefacer.oke then you get one stear pokemon
The only things that happen after you beat Red are that you are given the Kanto and Hoenn starters from Oak (in his lab) and Steven Stone (in Silph co.) Otherwise, congratulations! You just beat the hardest trainer in the game... and showed Ash Kechum who's boss.
Nothing. Red just disappears and doesn't come back. You can always make Red reappear by beating the Elite 4 again. Then just go back to the place where yu saw him
go to the place that you beat lance.after you beated him for the third time,hike up Mt.Silver and beat red to train your Pokemon to lv.100.
u r pretty much finished . you can beat the league again or just train
