If you're talking about Raikou, Entei, and Suicune,I used an ultra ball on Raikou and a dusk ball on Entei and Suicune.If you're talking about Articuno, Moltres, and Zapdos, I lowered down their hp and then used a dusk ball.
You can't.
Between Mahogany Town and Lake of Rage.
You don't, the three 'crown' Legendary Beasts are obtained via a wi-fi event for SoulSilver/HeartGold.
There is no such thing as mew three
in the burned tower go down the ladder and get to the three legendary dogs then they should roam around until you catch themHOPE THIS HELPS :-D
You could try to catch all of the legendaries this includes the three birds, ho-oh, kyogre, and the three Pokemon that run around also, red happens to be wating on top of the mountain, so good lcuk to you
Nothing happens after that. You just caught the three legendary roaming Pokemon in the Johto Region.
You catch it in turn back cave. To get to him go through go through random doors and you will find three pillars in different rooms then the next room is giratina's room. If it takes you more then 30 rooms to get to all three pillars and giratina's room then you start over again.
By Ruby I'm assuming you mean the Hoenn starters, then yes, you can get one of three of them in HeartGold/SoulSilver
Only on Pokemon yellow.
for the Pokemon you can catch
Trade them from HeartGold and SoulSilver.
