You can't, only on Pokemon XD. Brief advice:
1. YOU MUST, if you have XD, CATCH LUGIA WITH A MASTER SNAG BALL!
2. Grand Master* Greevil's Shadow PKMN
Shadow RHYDON
Shadow MOLTRES
Shadow EXEGGUTOR
Shadow TAUROS
Shadow ZAPDOS
You cannot migrate or transfer Shadow Lugia over to Pokémon Ruby, Sapphire, Pokémon FireRed, LeafGreen or Emerald. You will have to purify the Shadow Lugia using the Purification Chamber and then you will be able to send it to Ruby, Sapphire, FireRed, LeafGreen or Emerald.
i dont think you can if you mean shiny then u need a action replay there not much but there worth it.
well there is no shadow lugia but u can change it into a shiny lugia if u get action replay. sometimes when you see Pokemon they are shiny which just means different colors then originally.
No, you can't. The only Shadow Lugia is in Pokémon XD Gale of Darkness. You can't trade the Shadow Lugia to your GBA games, but once purified, you can.well you can but you have to use a shadow orb make it hold and then you have a shdow lugia
