Yes.
Transfer it from Ruby, Sapphire, Emerald.
or
Trade it from SoulSilver.
You must find AR codes for latios/latias are not wild in Diamond. I do not have an AR code for latios/latias. Sorry.
no
You can't possibly catch latios in Pokemon diamond although you may get it there by using your ruby version if you have one to import it to your diamond. another way is to buy an action replay and cheat
Cant get one on pearl or diamond.
you don't. there is no way to get latios OR latias in d/p. You can migrated it from earlier games though...
dude or dudet u cant get a latios or latios in Pokemon diamond/pearl. so stop asking by the way u can only get em in ruby emerald sapphire gosh buttox rox :p licky
need to migrate or trade
No, Latios cannot be caught in Pokemon Diamond, Pearl, or Platinum. You will need to migrate it from the Generation III games to the Pal Park or trade for it with a nearby friend.
Use action replay code. That's how i did it
Of course and also in diamond.
the only Pokemon i have come across that has luster purge is Latios. you can get latios in ruby sapphire and emerald you can't get latios in diamond or pearl Added by partone: so can latias
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.
