First you have to find it which you can find it pretty much anywhere the best route is Route 1. Use a masterball on it to easily capture.
Suicune is not in the Sevii Islands.
You can't. You have to migrate from LeafGreen or FireRed.
you can only get it by getting bulbasour as your starter.beat the elite 4. then find it in the wild
Suicune is not a possible starter Pokemon in emerald you must get a suicune from Pokemon firered or leafgreen.
Entei, Raikou, and Suicune are NOT obtainable in Pokemon Platinum.You will either need to catch them in Firered/Leafgreen and migrate them or trade with someone else that has them.
Suicune is not in emerald so trade one from firered, leafgreen or Pokemon colosseum to get one.
This is VERY debatable. Most say Mewtwo, Mew, Raikou, Entei, Suicune.
Suicune is on Firered. She can be caught with a Charmander there. Leafgreen too. Trade her to Emerald.
if you have firered or leafgreenyou will be able to catch entei ,raikou, suicune only if you beat the elite four then when you catch the three lengendaries then migrate then into Pokemon diamond
trade or capture
there isn't a wild suicune to catch in white or black
To catch a suicune in firered, you must need : to have chosen charmander as a starter, beaten the elite four, and have national dex. Bulbasaur : Entei Squrtle : Raikou Charmander : Suicune
