You cannot get Mario's younger "Bro" in Pokemon Gold. You can obtain Lugia at Whirl Islands in Pokemon Gold and HeartGold. Whirl Islands is located on the water route between Cianwood City and Olivine City. You need to first get the SilverWing or Tidal Bell to access Lugia.
If you are talking about luigi, you can only find him in Mario games. i don't know where lugia is though. you cant catch him in Pokemon pearl trade from heart gold or soul silver or use action replay
Luigi Isn’t Pokémon!
Luigi is not a Pokemon and cannot be caught. If you want to catch Lugia, you will have to get the special event which is no longer available. Therefore, you will have to trade it from another game if you want to get it on FireRedNo, there is no such Pokemon as "Luigi" in the Pokemon games. Luigi from the Mario series isn't in the game, either.
It's LugiA, not LuigI.
