In terms of getting through the first few gym Bulbasaur is the best until you can pan your team out, but the other starters can quickly be covered as you pass through the routes (such as Mankey to help with Brock in Pewter, and Oddish/Bellsprout to help with Misty in Cerulean)
you can not catch bulbasaur you have to pick him as your starter Pokemon
You can't it is a starter that you must pick at the beginning of the game.
Answer:no, but technically Suicune is "released" to roam freely around the region if you pick the fire type Pokemon as your starter.
Kanto starters are not available in Sapphire you'll need to trade them from Firered or Leafgreen.
Just walk into the long grass north of Pallet town, and oak will allow you to pick one.
Sucuine does not exist on Pokemon Pearl. I believe it is in FireRed/LeafGreen if you pick Charmander for a starter, roaming the wild after you beat the Elite Four.
Entei doesn't have a specific location, but they are roaming around Kanto after you beat the E4, get the National Dex, and give the Ruby and the Sapphire to Celio. The legendary dog that runs around Kanto is based on the starter that you pick. When you pick Charmander as your starter, Suicune roams around Kanto. When you pick Squirtle as your starter, Raikou roams around Kanto. When you pick Bulbasaur as your starter, Entei roams around Kanto.
If you want to know what starter Pokemon in emerald you should pick, Treeko because if you pick Torchic it will be harder when you battle the elite4 because Blazikan is so good.If you pick Mudkip you will have a hard time when you battlle your rival. So I would want to pick Treeko.
You should use it on either entei, raikou or scuicune if you pick squirtle ull have raikou if you pick bulbasaur ull have entei and if you pick charmander youll have scuicune
In leaf green you should start with bulbasaur because the first 2 gyms are weak against grass Pokemon
all you do is get the national dex, talk to professor oak and he will let you pick one of the three johto starter pokemon. get every Pokemon in the national pokedex and show prof. oak. then you can pick between it, cindaquill, and todadile.
No you cannot find Hoothoot in FireRed but you can trade from Pokemon Emerald.
