Well, when I beat the game I used a lv.61 Meganium, lv. 31 red Gyrados, lv.31 Dragonair, lv. 42 Entei, and the rest were no help. But the Dragon and the Dark Elite 4 were the hardest. Make sure (if you have one,) your Meganium knows razorleaf, bodyslam, and I forget. but Entei knows pretty weak moves, but definitally comes in handy when you come to the Dark Elite 4.
The Elite Four Champion in Pokémon SoulSilver Version is Champion Lance.
well... for me i used my strongest Pokemon in the battles against the Elite 4... but it all depends on the kind of Pokemon that you have caught and their levels as well
you should have an ice type Pokemon, a fighting type Pokemon and an electric type Pokemon
Red goes to Mt. Silver in the Crystal Version. You can fight him after you beat the Elite Four.
The oldest Pokemon games to feature Johto are Gold, Silver, and Crystal. FireRed and LeafGreen partially feature Johto after you beat the Elite Four. The newest games to feature Johto are HeartGold and SoulSilver.
the elite 4 is in kanto
Lugia because it is physic and super affective against poison and fighting but don't use it against dark because they will kill it easily
You have to beat the Elite Four first, then you can use the game sync to trade between them, your welcome :)
They are at indigo plateau
eat poo
after you beat the elite four, you can go to to the Kanto region. (at least i think its Kanto its the one with Brock and misty) at the first city, pewter town, there is a man next to the Pokemon center after you beat Brock he will give you the silver wing (gold version) or the rainbow wing (silver version).
get one pokemon to level 100
