You can't without hacking, unless you have HeartGold and SoulSilver. Why, one word, HM Moves, Rayquaza can't migrate, you need to get Rayquaza on the Nintendo DS. (This requires HeartGold and SoulSilver. You need both, you'll see why...)
You cant. You have to migrate it :)
yes
you cant. you have to trade it from another game.
You can't really catch Rayquaza through normal gameplay. However, you can migrate Rayquaza from Pokemon Ruby, Sapphire, or Emerald version to Pokemon Platinum version.In the tower near the place you find Spirtomb passed Hearthome City and below the town with the Daycare.
no
You can catch a Rayquaza by migrating it from Pokemon Ruby, Sapphire, or Emerald to the Pal Park with 100% catch rate. But the only other ways are to trade for it or use a cheating device such as an Action Replay.
You can't find rayquaza in pokemon platinum.
No you cannot. Rayquaza is only obtainable in Pokemon Ruby/Sapphire/Emerald and you must migrate it to Platinum.Or if you have Pokemon Heartgold/SoulSilver you can catch Rayquaza using a green orb if you have both Groudon and Kyogre in the game.
You can't catch Rayquaza in Black or White. You must transfer it from Diamond, Pearl, or Platinum.
Spear Pillar is at the top of Mt. Coronet (Sky Pillar, where you catch Rayquaza in Pokemon Ruby, Sapphire, and Emerald, does not appear in Platinum).
no way
You can catch Rayquaza in the map called "Blackthorn City".
