they are in different spots in every game, and not all of them are in a game, but they are usually hard to find like:ho-oh (bell tower), Lugia (whirl islands), mewtwo (seafoam islands- in FireRed and LeafGreen), and many more, but there is only one Pokemon that can be received only in Nintendo events. That Pokemon is...
CELEBI
Ho-oh
Riakou
Entei
Suicune
Articune
Zapdos
Moltres
Kyogre
Mew-two
Raquaza is when you get both Groudon (SoulSilver) an Kyogre (Heartgold) to Emmended Tower.
(Dialgia,
Palkia, and
Giratina is only with the special event Arceus)
Latios is only when you bring the Eginema Stone to Saffron City, then the fossil museum
Latias
Some conditions apply for these Pokemon I think. And I have heard people talking about an event happening for Celebi.
you get ho oh in heart gold and in soul silver you get lugia. You can still get Lugia in heart gold too, somewhere in the whirl islands, mewtwo, in the cerulean cave, zapdos, in the power plant, moltres, in Mt. Mortar, articuno, in the seafoam islands, kyogre, in a cave near thr safari zone, and dakrai, celebi, and jarachi but i have no idea how to get them! sorry! :)
