You can catch every Pokemon, you can do the arceus and groudon events, you can Get
a kanto starter from professor oak, a hoenn starter from steven at the silph building, you can catch mewtwo
you can trade from red to emerald to diamond the to soulsilver
If you mean how to consider yourself as beaten the kanto region in pokemon soulsilver, then you should find zapdos,moltres, and articuno. You should also beat Red (Ash Ketchum). Once you do that, you can catch Mewtwo.
Red Gyarados should be catchable in heartgold/soulsilver like in the original gold/silver series. Itt should be caught in the lake most northern of the johto region. hope this helps you. =)
Well first I should clear up that the Red Orb is for SoulSilver, and the Blue Orb is for HeartGold, but you must defeat Red in order to get it.
Yes, Pokémon HeartGold and SoulSilver has Mt. Silver and Red.
You can't. You have to get Pokemon SoulSilver if you would like the red orb or trade with a friend. The red orb is only obtainable in Pokemon SoulSilver.
find the red orb and go to cianwood city and then go to embedded tower and he/she should be there!
you have to defeat the elite 4 again, then go 2 Mt. Silver where u first saw Red. he should be there.
You can find Red in Mt. Silver.
You will find Red at Mt. Silver.
He vanishes.
yep
