There is no Missingno. anymore.
Its impossible to catch any hoenn Pokemon in firered if you want hoenn Pokemon like groudon and kyogre trade them from ruby, sapphire or emerald to receive them in firered.
navel rock, if you want to catch it you need a cheat code device
You cnnot catch it in Pokemon fire red ,but you can catch it in Pokemon Diamond and Pearl.If you want it to be in your fire red,you will have to migrate it from your Diamond/pearl to your fire red.
You can't, if you want it you'll have to transfer one from Ruby or a friend who has one.
You can't get totodile if you want one trade croconaw from colosseum then breed it.
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.
You can only catch lugia if you migrated it from firered or leafgreen. If you want lugia get one from heartgold or soulsilver version.
No two Pokemon make mewtwo ,you must catch it in firered or leafgreen and if you want you can migerate it to diamond or pearl.
Clone Evees in the day-care center, until you have as many as you want.
After you catch mewtwo you go and beat the Pokemon league again to go and catch the legendary dogs!!!!!!!!!!
You need the bad egg cheat then the egg will hatch and will crash your game. Pokemon put in by mistake. It was supposed to be a starter in a newer game, but they let it go. Trust me you don't want a Missingo, they suck anyway.
That is impossable. If you want lugia you need the wonder pass in Pokemon Emerald Version, which you get at wonder spots. No need to thank me[:-)
