Only with action replay
you have to have action replay
You can't.
You can find lugia in navel rock
No but you can get Lugia in Pokemon Xd just trade it to a GBA Pokemon version like Ruby then trade it to colosseum.
you don't.....you trade them......
you cannot catch lugia in ruby/sapphire/... you have to trade from fireRed, and leaf green. to get lugia you have to go to navel rock either in emerald, fire red, and leaf green
Sorry but you can't catch it in ruby. You canonly catch it in diamond or pearl.
You have to trade from Pokemon XD or Ruby, Sapphire, Emerald, Leafgreen, or Firered.
Rare Pokemon come randomly when you're in the grass or cave.
You cannot trade Pokemon to Pokemon Colosseum, but you can trade the Lugia you catch to Ruby or Sapphire.
Shadow lugia is unobtainable in any game excluding Pokemon XD: Gale of Darkness unless hacking is used
The only way is to trade it from another game, like XD.
