After you beat the Elite Four, one of the legendary dogs from Pokemon Silver/Gold will be released into the wild. Which one you get is based off your starting Pokemon. Its just a random chance to see them in the wild. A good strategy is to choose a Pokemon around 35-39 like Gengar and run around areas using repels til you find one of them.(Gengar is a good choice because he is fast and can use Mean Look; all 3 of the dogs will run away from you)
If you choose:
Charmander, you will see Suicine in the wild
Squirtle, you will meet Raikou in the wild
Bulbasaur, you will meet Entei in the wild
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!!
well u must go catch entei suicune and raikou.
if you have Pokemon firered,leafgreen,emerald or ruby in you GBA slot with suciune in the game go to pal park go inside this grassy runny thingy and run around the field and you'l have your suicune migrated to Pokemon diamond
you should go to gamestop
go to the rainbow islands(islands 5,6 nd 7) and capture all the pokemons......!! I knoe the best pokemons for you to catch.....mewtow in cerulean cave...you have got to surf for that.....and suicune, entei or raiku depending on which your starter Pokemon is.......entai for bulbasaur..suicune for charmendar.....and raiku for squirtle!
You have to go to Silph Co in Pokemon LeafGreen. You have to go there to get the Silph scope, which you need to advance.
In fire red and leafgreen entei suicune and raikou are all catchable legendaries, the problem? you only get one and it depends on the starter Pokemon you chose, bulbasaur=entei, squirtle=raikou, charmander=suicune, so how do you get em all? 2 ways to do this: One get entei/raikou/suicune trade it to a different game erase it then catch the one you didn't yet repeat this step again until you have em all in your possession, Two the easier alternative, in Pokemon colosseum these legendaries are catchable as shadow Pokemon and if you purify them and beat the game and have a GCN to GBA cable you can go to phenac city go downstairs at the Pokemon center and trade all 3 to leafgreen or firered then migrate them to diamond or pearl.
there is no Pokemon that can go higher then lvl 100
you go to kanto or if you give me lugia i will give you suicune lv100
you can catch suicune if your starter is charmander and go to the place where you go to the virdian forest but don't go in the entrance there's an path of grass use a bike the use a max repel the if your bikes stops but you donts stops that's means when the max repel turned off its means you got suicune when you battleAt navel rock or take the one from Pokemon colosseum.
Well, if I were you, I would go into a room with Suicune in it. (but the Suicune could be low level). I did this and I got one. I hope this helps.
go to the Pokemon lab on cinnbar and go to the last room talk to the dude by the machine. he well transform them for you the Pokemon will be at Lv5.
