You must defeat the eighth Gym Leader in order for Articuno to appear. First, you go to the Seafoam islands. Delve deep into it and you can find Articuno.
Articuno is in Seafoam Island.
I have Articuno I found that dusk balls are the best I caught it with it!
You can get Articuno in Pokémon Red, Blue, Yellow, Platinum, HeartGold and SoulSilver, in Red, Blue, Yellow, HeartGold and SoulSilver, you can find Articuno residing in the Seafoam Islands. In Pokémon Platinum, Articuno starts roaming around the Sinnoh region once you've spoken to Professor Oak in his place in Eterna City after you have received the National Dex and beaten Cynthia.
Go to Blanies gym and when you go in before you go up the later go on the left and see the ice path? go through that maze and there will be Articuno!
Yes, all 3 of them (Articuno, Zapdos and Moltres) will be in Pokémon HeartGold and Pokémon SoulSilver.
The legendaries on Soulsilver are as follows: Entei, Raikou, Suicune, Lugia, Ho-oh, Groudon, Latios, Rayquaza, Mewtwo, Moltres, Articuno, Zapdos. These are the legendaries found on Pokémon Soulsilver version. ~CareyPrice31FTW
Lugia,Ho-oh, Raikou, Entei, Suicune, Latios, Mewtwo, Zapdos, Moltres, Articuno, Groudon.
It's your opinion, but in HeartGold you can catch Ho-oh, Suicune, Raiku, and Entei, and in SoulSilver you can catch Lugia, Zapdos, Moltres, and Articuno. There are also more Pokemon available in HeartGold than SoulSilver. Edit: The person who last answered this question is wrong, you can catch all of the above Pokemon in both games, not in either or. I know this because I have soul silver and I have suicune, raiku, Entei, Ho-oh, Lugia, Zapdos, Moltres, and Articuno; so obviously you must be able to catch them in both.
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.
In Diamond and Pearl you can't catch Articuno.
catch Zapdos or Articuno
you don't catch articuno in crystal but you can get one from red, blue or yellow.
