First you have to have the starter Pokemon charmander( it can be a charizard ) and then get lucky by walking around in a patch of grass.
Use a Master ball on Suicune but there is an easier way get Suicune. Catch a Pokemon who has the ability of spell tag.
you cannot catch a suicune wild in platinum, hoewever you can migrate it from an other game like fire red.
depends on your starter. one of them makes suicune random in the wild (just like gsc) Josh
Zapdos, Articuno, Moltres, Mewtwo, Entei/Raikou/Suicune (depends on what starter you chose).
Blastoise, Gyarados, and Suicune.
You cnnot catch it in Pokemon fire red ,but you can catch it in Pokemon Diamond and Pearl.If you want it to be in your fire red,you will have to migrate it from your Diamond/pearl to your fire red.
to get it u need to have charizard.to get suicune use max repel and if a Pokemon appears its suicune!
start out with charmander
you have to have the action replay for it first. Then, go into the mystery zone, walk around there for a while and then suicune will pop up.how to get a suicune:you cant catch it in pearl you have to migrate it from fire red or leaf green whoever told you that is able to be caught in Pokemon pearl lied
four without cheats Articuno Zapdos Moltres Mewtwo plus one of the legendary dogs; entei, suicune or raikou
to get suicune on Pokemon diamond without action replay is to migrate from Pokemon fire red version or leaf green
