Where does Suicune first show up please help me!!!!!!!!!!!!!!!!!!!!!! ..

He shows up in Kanto,and it can be any wheres in the grass dude.

Use max repel and go to the grassy part area or water, try in vermillion city, I saw him there.

Just go around everywhere. If you actually look for him, it'll take forever. So just go around training youre Pokemon and he'll show up eventually. I found Entei while on my way to get Mewtwo.

Suicune is random and there is no specific place to find it.It is always in Kanto and not on the islands.

Well, first have you talked to Oak after beating the league and having your Pok�dex newed, so you can catch the new Pokemon, and if so, you can only catch Suicune if you started with Charmander.... Anyways the location is random, but I found him on Route 1.

Well he will only show up if your Starter is Charmander, also he is random and there is no specific location, I found mine on Route 1.

It can be any where in Kanto.

Here: If you've caught 60 Pokemon, and registered them in your normal Kanto dex, Oak will talk to you after beating the Elite Four. He will upgrade your dex to the National Dex, and that's when the chase begins. Suicune, Raikou, and Entei will start showing up randomly in the grass (Similarily to Gen 2) but, you can only find one and that depends on the Starter you chose.

Charmander=Suicune
Squirtle=Raikou
Bulbasaur=Entei

Once the requirements are met, (To save time) simply get 20 repels, and go to a grassy area next to or near a building (or cave) make sure to have a Pokemon under level 49 as the beasts are at level 50, and preferably one with sleep powder or mean look (at least for Suicune.) Spray repels, keep the level 49 or below Pokemon at the front of your party and walk around. If Suicune does not show up within 10-15 seconds, go into a cave, and exit. This will reset the dog and repeat the process until you find Suicune. I should note, that you could also use any grass in Kanto, save and reset, and that will cause the location of the dogs. Another note, while this works for all three dogs, Entei and Raikou, when encountered, can use ROAR and be deleted from the save file entirely. Even with Mean Look or a Pokemon with an ability like Arena Trap or Shadow Tag.

For catching Suicuine, as I mentioned, a Pokemon with Mean Look could be used to keep Suicune from running though only if your Pokemon is faster. Same applies to the sleep method, but if you use a Pokemon like Dugtrio with Arena Trap or Trade a trapinch over from Ruby, Sapphire, or Emerald, you could use that. Shadow Tag is found on the Wobuffet family and will keep Suicune from running...Though using Wobuffet is not suggested. Either way, dwindle Suicune's health down and use ultra balls to try and catch it. You should stock up on balls, or simply just use the Master Ball.
