Well, you see him/her/it in many places, but to catch it, you have to beat Misty(Cerulean City gym leader) and go to Route 25 to the place you saw Misty and Suicine comes, as well as Eusine, who allows you to catch it.
find it and catch it simple
In Pokemon Soul Silver, Suicune is at level 40! ^_^
while in the wild you will eventually find it though it might run away i remember when i found my suicune
you find him in ciawood city then he gose to a place where i haven't found yet
in the cerulian cape after seeing him at virmillion and this place with windmills near fuschesta
you go to kanto or if you give me lugia i will give you suicune lv100
Suicune is a hard Pokemon to catch Suicune will move around diffrent places. You normally catch Sucune at level 40 use your map to try and find Suicune on your pokegear. It is hard but you will get there
outside mt. motar where three apricorns are
you usally see it without battleing it and after the fifth time it locks you into battle
you won't be able to catch it.
nop sorry
In Pokemon Soul silver or silver or gold, the legendaries you can get is Lugia, Suicune, Entai, Raikou, Mew and Mew 2
