It depends on your starter.
for
Raikou: Squirtle
Entei: Bulbasaur
Suicune: Charmander
They come in the wild after you finish the league.
But beware: After one move they run away so keep your masterball ready.
In Pokémon LeafGreen, the wild Suicune will be found at Level 50.
Suicune is not available on XD. He is on Colosseum, and FireRed and LeafGreen if your starter was Charmander.
to get suicune in Pokemon fire red you beat the elite 4 and you have charmander as your starting Pokemon. Then go to a grass area with max repel....USE IT!!
with a pokeball. Suicune only apears if you choose charmander as your starter.
Suicune is not a possible starter Pokemon in emerald you must get a suicune from Pokemon firered or leafgreen.
What ever your heart desires.
watching lueroi's walkthrough on youtube
You can only get Suicune if you chose charmander. If you did, then it appears randomly. A trick is to have a level 40 pokemon (Wobbuffet or a pokemon with mean look) and have a repel, and run in a certain route. If it runs out before facing suicune, then leave the area and repeat. Eventually you will get it.
Not available on Sapphire. You have to trade from FireRed/LeafGreen
migrate from leafgreen firered starter has to be a charmander
to get suicune u have beat the elite 4 and get the national dex after that suicune will anywhere on the whole kanto region. start with charmander and suicune will be in the wild. HAVE FUN!!:)
In FireRed and LeafGreen, no. It randomly appears after you beat the game no matter where you are.
