I'm sorry dude but I don't think you can
just migrate it from leaf green/fire red
There are 4 without the Action Replay. Those are Articuno, Zapdos, Moltres and Mewtwo. WITH the Action Replay there are 8. Those are Articuno, Zapdos, Moltres, Mewtwo, Mew, Deoxys, Lugia and Ho-Oh
By sky Pokemon im guessing you mean rayquaza,moltres,zapdos or articuno then yes you can only get articuno,zapdos and moltres not rayquaza unless you cheat with action replay.
If Moltres,Zapdos or articuno runs away you need to use action replay to get them back
No
You can get most of the Pokemon without an Action Replay, which I thought was pretty cool. Here is a List: Lugia Ho-Oh Mewtwo Moltres Zapdos Articuno Raikou Suicune Entei Latios Groudon Those are the ones I found on Soul Silver without an Action Replay
Well techinicly you can't without cheating any more you get the legendary birds without cheating zapdos:power plant articuno:seafoam islands moltres:one island mewto"cerullean cave/unknown cave deoxys you have to have a action replay celebi you need action replay jirachi action replay mew action replay
So far your team is fine you should have each be in the 70 range so allow mewtwo and articuno and zapdos level up.
There is no National Pokedex in Pokemon Ranger, so therefore, there's a limit to the Pokemon you can capture. None of those Pokemon can be obtained in Pokemon Ranger without use of an action replay. In fact, I don't think an action replay will give you any of those Pokemon, either. Only the 200+ Pokemon that Nintendo selected for the game can be caught in it. Sorry.
---- 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.
You can catch Pokemon anywhere where there is grass and you have a Pokemon that can battle against the Pokemon you wish to catch until the Pokemon you wish to catch is weak enough to be caught by whatever type of pokeball you've either found or bought from a mart.
Two ways- first you can only get 1 master ball in the game and that's when u beat Cyrus in his headquarters-in storyline and the second way is by using action replay or gameshark or if ur friend has it trade a weak Pokemon and make his Pokemon hold a master ball and trade-----I did this and i caught articuno,zapdos, and moltres easy.
You can get Articuno, Zapdos, Moltres, Mewtwo, and, depending on who your starter Pokemon was, Entei, Raikou, or Suicune. If you started with Bulbasaur you see Entei, if you started with Squirtle you see Raikou, and if you started with Charmander you see Suicune. If you know people who received the Mystic Ticket and Aurora Ticket through Mystery Gift events, and you both own a Wireless Adapter for your Game Boy Advances, you can also get Deoxys, Lugia, and Ho-oh.
