I don't know how to get him easily but he's wild in kanto after you beat the elite four
you cat a
You catch raikou in vermilion city in the smallest patch of grass
You cannot catch Raikou in Pokemon Diamond and Pearl. To get Raikou in Pokemon Diamond and Pearl, you must trade for one from Pokemon HeartGold and SoulSilver where it can be caught or transferring from Pokemon FireRed and LeafGreen.
There's no specific spot to catch raikou because raikou is a wondering Pokemon it can go from route to route in kanto and this makes it hard to catch but all more worthwhile to catch it.
no cause you are a stupid
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.
This is VERY debatable. Most say Mewtwo, Mew, Raikou, Entei, Suicune.
You cannot catch the legendary dogs in Diamond or Pearl, you must migrate from Pokemon LeafGreen, FireRed, Colosseum, or XD.
You can catch raikou in fire red if you picked the starter squirtle, then after you beat the Elite 4, it will randomly appear in grasses.
You will find Raikou in the wild once you have defeated the Elite Four. Note that the legendaries are as follows: Suicune: Charmander Raikou: Squirtle Entei: ulasasour
raikou cannot be caught on Pokemon ruby
Migrate from FireRed. It's easier to get Paras in THAT game.
