In ruby and sapphire
Latias and Latios canot be caught. BUT you can migrate from Pokemon Emrald,Ruby, or Sapphire by getting the national dex, catching them in a Pokemon GBA game inserting your gba game turning on he system, and going to the main screen of your DS game, selecting migrate from(GBA game) and select latias and/or latios (as long as they don't know HM moves) and go to pal park and put on a catching show. Then, latias/latios will appear in pal park!!!!!!!!!!!!!!!!!!!!!!!
you cant catch latias or latios in diamond/pearl. you can migrate latias and latios from emerald, ruby, sapphire. in case you dont know, you get latias/latios at the end of the game and the mother tells you what color(red-latias/blue-latios) the guy on tv says. the hard part is to find it. it randomly appears any where on hoenn.
Yes you can. later in the game Latias (or latios depending on which game you have) is attainable. Like mesprit in Pokemon diamond and pearl and like mesprit, latias and latios tend to flee.
If you're asking if you can get an egg for Latios or Latias without breeding them, then the answer is no; you cannot get an Egg for either of them without hacking the game.
you have to migrate from a previous game
with a game shark
pewter city museum the only way to react with him is get the egnima stone from mystery gift depending on which game you have (hg latios will appearide) (ss latias will appear outside).that is where steven is.
Latios is roaming the region like Entei and Raikou so where you first meet it changes per game. If you are a girl in your game you will catch Latias. if you are a boy you will catch Latios. To get the other one that you didnt catch you would need the Egnima Stone, which is in a wi-fi giveaway. If you have it you go into the fossil mueseum and give them the Stone. When you go outside Latias/Latios will fly up to you and battle you. Hope this helped!
you don't need one if you have ruby you get latias if you have sapphire you get latios emerald you you choose when your mother is watching tv after you beat the game she jumps up and asks you what colour the Pokemon was say blue for latios red for latias trade for the other one
One way is to trade with another emerald or you could trade your latias (or latios) to another emerald then restart the game and choose the opsite then catch it and trade back.
It is possible, but you can't catch them both on 1 Pokemon game. If you have Pokemon Emerald, Ruby and or Sapphire. Then you can get them both. For example: Someone trade Latios and you have Latias, trade an another Pokemon for Latios and you have them both.
latios is leghendary and does not evolve in any game unless its a hack
