There is no exact location since Raikou moves around the Kanto map consistently. It will never appear however on the Islands including Cinnibar. Also it will never appear in Caves or in the water.
In the wild.
Raikou is only found in firered and leafgreen if you chose squirtle as your starter Pokemon. Or you can get the purified raikou from Pokemon colosseum.
Since it is a wandering pokemon, there is no definite place to find it. By the way, I believe it is Where IS Raikou in Fire Red.
Raikou is a legendary dog Pokemon. It is not in any specific location in Pokemon Fire Red. Instead, you can find it roaming Sinnoh.
it roams but u can only find entei in fire red.
no. you just find them all seperatly.
You can find a (as in only one of) the legendary dogs roaming your game after you have completed the national dex. You will get whichever dog is supereffective to your starter. Raikou-----> Squirtle Entei------> Bulbasaur Suicune---->Charmander
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
You will only find Raikou if you chose Squirtle as your starter pokemon. After you receive the National Pokedex from Oak, Raikou will begin to roam Kanto. the other way is to have a friend trade you one.
You can't find raikou in ruby.
Raikou? I think you mean Raichu. To get a Raichu, just use a thunderstone on a Pikachu and it should evolve into Raichu. To get the thunderstone, go to the Celedon Department store or find one at the power plant.
You find Articuno at Seafoam Islands,Moltres on top of Mt.Ember,Zapdos at the Power Plant Mewtwo in Cerulean Cave,Entei Sucuine or Raikou in the wild
