You must have chosen charmander as your starter Pokemon and beat the elite four and got the national dex and delivered the ruby and sapphire to celio. If you have accomplished all of this go to route 1 which is above pallet town and stay in the grass for a while eventually suicune will show its pretty face now use the masterball and you got it!
Suicune is not available on XD. He is on Colosseum, and FireRed and LeafGreen if your starter was Charmander.
trade or capture
Suicune is not a possible starter Pokemon in emerald you must get a suicune from Pokemon firered or leafgreen.
It can be found anywhere where grass is except on the sevii islands, the best spot to find it is route 1.
Suicune is not in the Sevii Islands.
Try Route 1.
your starter must be charmander then after you beat the elite four Suicune will be running randomly throughout the region
Not available on Sapphire. You have to trade from FireRed/LeafGreen
migrate from leafgreen firered starter has to be a charmander
Anywhere in Kanto after you beat the game using a Charizard. Suicune will only appear if Charmander was your starter pokemon.
you have to get charmander as a starter and then when you beat the elite four in firered you just have to look for him in a random place
Suicune randomly appears in the world map after you have beaten the Elite Four, and when you chose Charmander as your starter pokemon. -jean- :)
