You randomly run into him. Once you do he'll be on your pokedex and you can track him. It's trick though as every time you enter a town or fly any where he moves. i recommend you got to goldenrod and just keep walking into the city and out to the grass till you run into him.
Raikou is everywhere. After you find it in the Burned Tower, it'll roam Johto.
It is everywere once released from a burned down tower you visit
Suicune, Raikou, and Entei
Wrong game dude. You're thinking of crystal, gold and silver.
Raikou doesn't have a nest, it runs randomly around Johto.
yes.
It is running around in the wild.
Raikou is a wandering Pokemon and will roam about the jhoto reigon.It literally can be found anywhere in the grass on any route.
You can get lugia, ho oh, entei, suicune and raikou
the three legendary dogs are random appearances there is no more likely area
No, it is not true that Blaine will give you a Raikou in Pokémon Crystal. The only Raikou available in Pokémon Crystal is the one that roams around once you scare it away in the basement of the Burned Tower.
You can't find raikou in ruby.
