You have to beat the elite four and catch Mewtwo. If you started with Charmander, you will be able to catch suicune. If you start with bulbasaur, you will catch the fire type Entei. If you start with Squirtle, you will catch the eletric type Raikou. All have the same idea. Suicune/Raikou/Entei will be running around so you will have to meet up with them and track them down in your pokedex. If you use bike or Fly, they will be scared away. Use your Master Ball on them. Good Luck!
You can't find them in there.
In Pokémon LeafGreen, the wild Suicune will be found at Level 50.
Suicune is not a possible starter Pokemon in emerald you must get a suicune from Pokemon firered or leafgreen.
You can find them anywhere around the routes of kanto so look in the grass.
with a pokeball. Suicune only apears if you choose charmander as your starter.
Suicune will appear after becoming pokemon champion and delivering the Ruby and Sapphire to Celio in One Island.
Not available on Sapphire. You have to trade from FireRed/LeafGreen
Suicune will appear after becoming pokemon champion and delivering the Ruby and Sapphire to Celio in One Island.
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.
By Twilighticecream You get suicune if you start with bulbasaur at the begining of the game You can find entii, suicune, or raiku anywhere in kanto, buildings, grass, caves, anywhere. Not just the cerulean cave. You find mewtoo at the end of cerulean cave.
to catch suicune,mewtwo,raikou and entei
your starter Pokemon should have charmander because that's the only way. search around the kanto region and you should find it. NOTE: once you've seen suicune once, it'll be in your pokedex so it should be easier to find.
