Go to professor oak, Talk to him, he will give you the "super itemfinder" use it when using the map
give 'em 2 ur migrating Pokemon from saphirre, leafgreen, firered, etc.
you can't.:( but you can trade it from firered or leafgreen but to do that you have to get the national dex by catching 60 pokemon and getting all the items the aide has for you.if you own firered or leafgreen just go to google andtype in how to get MEWTWO. hope this helps:)
Bloodlax says: im fairly sure that i was a told that you can swap items from saphire, ruby, emerald, firered and leafgreen
Yes
Those items aren't in LeafGreen.
You can't :/
some items are used during pokemon trading.
you click use then click a Pokemon then remove an attack to be replaced with the TM u want. they are found in the TM case in the key items pocket.
Get the official guide of eBay or something and it tells you all the locations of items.
I think you need a Pokemon with a specialy natural ability that will dig up items if you walk over them.
Train your pokemon, Give it items, Have it hold the item Soothe bell.
You get money by selling items or beating other trainers in a Pokemon battle
