the three legendary cats, after you beat the elite four, one of them (depending on which starter you chose) will randomly appear in the grass. By the way, they are the legendary cats, not dogs. The Pokemon Company revealed that Raikou is a tiger, Entei is a lion, and Suicune is a cheetah.
you can't catch it because you already beaten the legendary
Nothing, because Mewtwo can't breed. None of the legendary Pokemon in the game are able to breed.
stupids you have to have a master ball and you cant fly to a tip is never use your strongest attack because that will just kill the pokemon the weaker your oponnent is the easier to catch it because it dosent have the stengh to get ot of the pokeball
It dosent evolve into anything because its already evoled
Arcanine is not a legendary Pokemon because legendary Pokemon can't be breeded and arcanine can.
He is rare but not a legendary because legendary means that there is only one of its kind.
---- Yes, there are pokemon catchable without action replay such as articuno, zapdos, moltres (leafgreen version), entei and suicune and raikou (leafgreen & firered version) and much more. ---- However, there are event pokemon, but probably do not use action replay. These pokemon might range from shaymin to arceus, but sometimes you can cheat for them, which is not guaranteed.
Because like every other legendary you only get 1 chance to get it so even if you run away you just gave up that chance to get it so that's why you must always save before trying to get a legendary pokemon.
No its not a legendary because in my Fire Red I see them EVERYWHERE!!!!! no its not a legendary Pokemon so its common
you cant because leafgreen is an older game then Pokemon pearl plus its a gameboy advance game.
You can't get it in Leafgreen, because it's a Generation IV Pokemon.
You can't evolve Yanma in Leafgreen. This is because Leafgreen was made before Yanmega was made. So basically in Leafgreen, Yanma is a Pokemon that can't evolve.
