These three Pokémon can't be found in a specific location in the Johto map. They're always prancing around the wild grasses (not caves) in Johto. You'll have to search around to find them. Once you run across one, it'll be registered in your Pokédex. You can keep track of its location by selecting "AREA" on its Pokédex entry page.
To get a chance to meet them, go to the Burned Tower in Ecruteak City. Break the rock in the way and fall down the little hole. Walk up the stairs and they will awaken and scatter.
These Level 40 Pokémon will never attack you, as they always run away from your sight on the first turn. Fortunately, when you damage it it'll stay damaged to make catching it easier. If you knock them out however, they are gone for good.
A strategy to make them easier to find is to use Repel and place a Level 39 Pokémon on the top of your party.
They can be found on any grass route (not in the kanto)
Yes! Entei and Raikou are traveling in Johto Region and you can catch them there, but Suicune only be found in route 25 of Kanto Region. Hope this help!!!!!!
Suicune is in a set location, and the story will lead you along to find it. Entei and Raikou are roaming around all the time. You can see them on the map, but everytime you enter a new route, or go in your bag or pokemon, they will move. So it's tricky.
There's actually three: Raikou (electric), Entei (fire), Suicune (water). Raikou and Entei are roaming, so use your pokegear to know where they are. Suicune has fixed locations (in order): northern Cianwood city outside of Mt. Mortar (you'll need cut) Vermillion city Route 14 Route 25 (outside bill's house)
On route 5 there is a forest that you can enter but you need the shiny raikou suicune or entie event
Depending on what starter you chose you can get one of those Pokemon. After you beat the game you can capture one of these Pokemon but there very hard to find because they move from Route to Route.
Suicune is on Route 25.
Suicune is probably not on route 25 if you met him everywhere else because you haven't caught Entei and Raikou. If you caught them and Suicune still isn't there then look at the places Suicune was, then go back to route 25 WITH ENTIE AND RAIKU IN YOUR PARTY!
go by lavandar town
After you defeat the elite four, Raikou and Entei run around Johto. (Suicune can be captured in Kanto.) Your first encounter with Raikou is completely by luck and chance, but once you see raikou once, you can keep track of what area it is in. again, Raikou can be found in every route in Johto, but he changes location each time you enter a building, go to a different route, or enter a city.
in the kanto riegone at the top of the hill at bill's house
In Pokemon Soulsilver you can face Raikou at Level 40, Entei at Level 40, and Suicine at level 35. To catch Suicine youll have to chase him. Hell first be in Cianwood City, Then Route 39, then Vermilion City, then Route 14, then Route 25. Youll encounter him on Route 25 at Level 35.
to find suicune go to curelean city towards route 25. it'll be standing there waiting. Entei, Raikou. Roam around
