In many ways, no. Fire has a national pokedex, alternate areas, and the chance of finding the legendary dogs!
You cannot catch the legendary dogs in Diamond or Pearl, you must migrate from Pokemon LeafGreen, FireRed, Colosseum, or XD.
moltres
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!
yes but it depends on who and what you are fighting
No
you dont find the legendary dogs in fire red. instead you get the legendary birds. they are zapados moltres and articuno
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
migrate from firered and leafgreen
no you cant and how would that even work.
gatch them with a master ball but trade the master balls
You need to migrate each from either firered or leafgreen or you can trade with heartgold and soulsilver after they got them.
it depends on which starter u chose. squirtle: raikou. bulbasaur: entei. charmander: suicune.
You can only catch one of the dogs which depends on what starter you chose to get the rest get one from firered to get the second and the third from Pokemon colosseum.
You can only get 1 which is decided by what starter you chose. To get the other 2 either have another firered or leafgreen give you the other 2 or take the purified ones from Pokemon colosseum.
No
The only way to get the Legendary Beasts in Pokemon Pearl is to find them in FireRed, LeafGreen, HeartGold or SoulSilver, catch them and then migrate them over to Diamond via Pal Park.
