Rayquaza has no specific hold item(like ho-oh's sacred ash or Chancey's lucky punch). however, i would recommend dragon claw, leftovers, and amulet coin.
Unfortunately not, but it is possible to clone items
no you can't let Pokemon hold key items
You need to have a Pokemon hold the item then trade the Pokemon.
NO. Pokemon can hold pokeballs, items, mail, tm's, berrys but not key items.
In your list of items press a on the item you want them to hold then in the list of options it should say Give and then shows a list of the Pokemon in your team then press A on the Pokemon you want to give it to.
Pokemon cannot hold items in Pokemon Blue, Red or Yellow. It was introduced only in the Gen II games.
There is no limit
your Pokemon can only hold 1 item at a time also it can only hold items that you give it on Pokemon pearl, diamond, or platinum so if you give your chatot an oran berry than that's what itll have on battle rev.
Train it, give it items, have it hold soothe bell.
the two items are pokemon and respect
if you want a Pokemon to clone and hold an item, you will just delete your profile.;)
Train your pokemon, Give it items, Have it hold the item Soothe bell.
