What is every legendary in Pokemon HeartGold?

Answer 1

The legendaries that are able to be caught are Ho-Oh, Lugia, Suicune, Articuno, Zapdos, Moltres, Mewto, Kyogre, Rayquaza, Latios, Raikou, Entei, and if you have an Arceus from the recent movie event, you get to choose from Dialga, Palkia, or Giratina to keep. This is in Heart Gold. In Soul Silver, you don't catch Kyogre, but instead Groudon. You also do not catch Latios, but Latias instead in Soul Silver.

Answer 2

Pokemon Heart Gold is a Generation IV game. This means that you can obtain, through various methods, all Pokemon from Generation I, Kanto (Red, Blue, Yellow), Generation II Johto (Gold, Silver, Crystal), Generation III Hoenn (Ruby, Sapphire, Emerald), and Generation IV Sinnoh (Diamond, Pearl, Platinum). The first 493 Pokemon are available. From Bulbasaur to Arceus.
