MIGRATE FROM POKEMON RUBY, SAPPHIRE, OR EMERALD AT PAL PARK AFTER GETTING THE NATIONAL POKÉDEX.Pokémon!
You must find AR codes for latios/latias are not wild in Diamond. I do not have an AR code for latios/latias. Sorry.
you don't. there is no way to get latios OR latias in d/p. You can migrated it from earlier games though...
Yesh. Latias is a girl. The guy version is Latios.
The only way to get a latios or latias in your Diamond or Pearl is to migrate, latios from Ruby or Emerald. latias from Sapphire or Emerald.
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.
need to migrate or trade
You cannot breed latios or latias even if they have genders they are legendary Pokemon so you cannot breed them ever.
Latias and Latios
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.
Capture either a latios or latias
The only way to obtain a Latias in Pokemon Diamond is to have it migrated. Latias is not a Pokemon that is encountered naturally in that particular game. The only game that does have Latias is Sapphire version (which can trade to other games, respectively). Thus, to have a Latias in your game, you must either use a cheat code or migrate it and re-capture it in the Pal Park.
Go and catch the other legendaries regirock,registeel,regice,rayquaza,latias or latios depending on version ruby latios sapphire latias emerald both
