Near Bill's house in Kanto. Past the Nugget bridge, Past all the trainers to the right. Keep heading to the right. Past Bills house and up the stair case. I think you need to beat Misty though. :L
Anywhere around kanto usually its found on route 1.
No, it only wanders around Kanto mainland.
You can't obtain suicune in Pokemon Diamond. You have to migrate it from your Pokemon Firered or Leafgreen. To find suicune in either Firered or Leafgreen you must have the National Dex, and you should have chosen charmander as your starter. Suicune will appear anywhere (except for caves) in Kanto - similar to catching Latias/Latios in Pokemon Ruby and Sapphire.
you can find suicune all over kanto but not at the sevii islands and you can catch him with a ultra ball only if his life is at red and he has a status problem. you can trust me i'v been playing for over eight years.
to catch suicune you need to teach a snorlax rock smash and repetidly (dont care if i misspelled any words)attack suicune ....pack alot of dusk balls
suicune is located in the kanto region by the cerulean gym by billys house after you see billy you will see suicune by the gate.
you go to kanto or if you give me lugia i will give you suicune lv100
Suicune is not in the Sevii Islands.
You can catch him at the top right corner piece of land in Kanto, See related link below for the Kanto map. It has a dead end in the top right corner, that's where suicune is, but you have to find him everywhere else in Kanto and Johto region.
Anywhere in Kanto after you beat the game using a Charizard. Suicune will only appear if Charmander was your starter pokemon.
After you beat all of the kanto gyms, go to cerulean city and go to where you saw misty with her "date". Suicune will be waiting there.
once you get to the kanto region, suicune is waiting for you near bill's old house, north of cerulean city
You can catch Suicune at Kanto Route 25. If you run away or Suicune faints you can have a rematch at the Burned Tower.
after u follow suicune all over johto, beat the pokemon league. then follow it around kanto. you will also run into eusine several times. after he realizes that suicune likes hills and water go to cerulean cape in kanto after u beat the cerulean gym. suicune will be waiting for u.
to get suicune u have beat the elite 4 and get the national dex after that suicune will anywhere on the whole kanto region. start with charmander and suicune will be in the wild. HAVE FUN!!:)
I believe its next to Bills house.
Kanto, the fourth time you meet it.
