You just need one of them.
look around for Suicune/Entei/Raiku
You have to trade or migrate. You can't catch them in diamond.
You can catch Mewtwo, Suicune, Entei, Raiku, Ho-Oh, and Lugia.
if you have firered or leafgreenyou will be able to catch entei ,raikou, suicune only if you beat the elite four then when you catch the three lengendaries then migrate then into Pokemon diamond
unfortunately you can't catch all 3 however depending on the starter you chose lets say its bulbasaur then you will find entei, if you chose squirtle you get raikou, and charmander gets you suicune. i don't know about gold and silver but in crystal you catch suicune in a standard battle at the tin tower ant raiku and entei will be in the wild but will always run from you
H0-OH , Lugia , suicune , entei , raiku . . . i think
you have to fight your way to the bottom of the tower. there, you will find suicune, raiku, and entei. then, when they see you, they will run away and you have to catch them(either catch or defeat, really).
You can't.
yes
Go get a celibi need suicune raiku entei and go to eterna forestthis will only work for diamond
Entei does not stay in one place, when you go to the burned tower you will see all 3 Legendary dog pokemon, when you go down to where they all scatter. Then you look on your pokegear map and you will see Entei and Raiku on there. then you try to catch them. Suicune, you can only catch him when you beat the Elite 4
go to the rainbow islands(islands 5,6 nd 7) and capture all the pokemons......!! I knoe the best pokemons for you to catch.....mewtow in cerulean cave...you have got to surf for that.....and suicune, entei or raiku depending on which your starter Pokemon is.......entai for bulbasaur..suicune for charmendar.....and raiku for squirtle!
