There are Pokémon from Johto in Leaf Green, however you can only find them on the Sevii Islands. (That is after you beat the Elite Four)
If you are talking about catching them, you cant unfortunately. I tried. but you get them as a starter Pokemon in the johto region.
sneasel can be found in leafgreen at icefall cave on four island, gligar can be found in the johto area of the safari zone in Pokemon emerald.
Piplup does not exist in Pokemon LeafGreen or FireRed.
Charizard is the late evolved form of Charmander which is a starter pokemon at the start of Pokemon Firered you can only get this pokemon through the beginning or by trading one from another Firered or even Leafgreen.
In the Johto region you have to get it as a starter Pokemon

It is a starter pokemon. You can not find it in the wild. You can also trade for it.
Yes you can by using action replay to catch your rivals starter Pokemon with the code for catching trainers Pokemon
well, you can see a trainer with it in the battle tower/battle foniter
If you have the starter Squirtle, you will find Rakio in the wild after beating the Pokemon League.
Actually, I think it's on the high side. In Pokemon Red, Blue, Yellow and Green, (JP) Johto Pokemon weren't yet invented. But in Pokemon FireRed and Leafgreen, you could find Johto Pokemon in the wild as well as trade Hoenn Pokemon from Ruby, Sapphire, Emerald, Colosseum, and XD later in the game. Since HeartGold and Soulsilver are remakes, much like FirRed and Leafgreen, their will probably be Johto and Kanto Pokemon like Gold, Silver and Crystal, along with Hoenn Pokemon later. Then again, FireRed and Leafgreen had Johto Pokemon only on the Sevii Islands. HeartGold and SoulSilver probably won't have the Sevii Islands, but will have Kanto. Since you could find Johto Pokemon in Kanto in Generation II games, you should be able to find Hoenn Pokemon in Kanto. Just another guess. Hope I helped. Thanks! Yes.There are a bunch of hoen Pokemon in HG ans SS. Including starter Pokemon (treecko, torchic, and mudkip) which are given to you by Steven Stone after you beat Red on Mt. Silver.
You can't get Totodile in Pokemon Leaf Green Version. Totodile is a Johto Pokemon, while Leaf Green is a Kanto version. The starter water Pokemon in Leaf Green and Fire Red is Squirtle. I don't think you can even get Totodile in a trade.
You cannot find Charmander in the wild in Pokemon LeafGreen. You will have to choose it as your starter Pokemon at the beginning of the game. If you chose another Pokemon, you will have to trade with someone to get it.You can get charmander only at the beginning of the game.
The first starter you get a phenac city after beating the game you can find the others at the shadow Pokemon lab and snagem's hideout.
there is no cecilio,,, celio only,,, you can find him in the johto region,,,
Raikou is only found in firered and leafgreen if you chose squirtle as your starter Pokemon. Or you can get the purified raikou from Pokemon colosseum.
