yes
of course you can
Rayquaza can be caught in Ruby, Sapphire and Emerald in the Sky Pillar. However, in Pokemon Emerald it can be caught before defeating the Elite Four. It can also be caught in Pokemon HeartGold/SoulSilver after obtaining the Jade Orb by showing Professor Oak both a Groudon and Kyogre from both HeartGold and SoulSilver (one of the two must be traded).
actually, you can just call them on the pokegear and just see what they say if they wanna meet somewhere that means they wanna battle
you need to go to ecruteak city and go right and before you go into the cave someone woll bump into you and give it to you. you should be able to use it right off the backWhen you try to enter Mt. Mortar, a man will give you it when you try to enter it the first time.
In SoulSilver, you have to defeat the Kimono girls, and then follow them to the Whirl Islands before battling the Elite Four. In HeartGold, you must first get the silver feather from an old man in Pewter City. Then you can finally go to the Whirl Islands to battle Lugia.
It is on Cianwood City Island. You have to surf there from Olivine City. (NOTE: the gym in Olivine is actually the 6th Gym battle so go to Cianwood Gym first) Before you go to Cianwood City make sure you visit the Olivine lighthouse top floor to talk to the Olivine Gym Leader about a sick Pokemon first.
heartgold and soulsilver
If you're playing Diamond, Pearl, or Platinum, head north from Solaceon Town to the Psyduck blocking the road. If you are Playing HeartGold or SoulSilver, head to the top of the Lighthouse in Olivine City and give it to Jasmine.
preordering is buying something before it's released and they mail it to you on or after the releasedate...To preorder Pokemon heartgold and/or soulsilver go to http://www.play-asia.com/
Yes you can catch it before the elite four, you can get larvitar after the zafari zone opens in heart gold soul silver which opens after you deliver the secret potion to jasmine of Olivine city. Larvitar can be found in the mountain region of the zafari zone but is rare.
In this order: Johto: New Bark Town, Cherrygrove, Violet, Azalea, Goldenrod, Ecruteak, and then in the order you decide, Olivine, Cianwood, Mahogany, Blackthorn. Kanto: Depending what routes you take: Vermillion, Saffron, Cerulean, Lavender, Fuschia, Celadon, Pewter, Viridian.
of course you can
The answer is put Rilou into the poke'walker before you enter and then when you get in put Rilou back into your game.
heartgold and soulsilver before and after elite four and other ds ones after elite four
You can either get it at the place that is right before the safari zone or before moomoo farm. (but i have heartgold so it may be different i dont know...)
You have to first travel west through Cianwood and Olivine and get badges 6 and 7 before you can head east to Blackthorne
well it comes after America, but before Europe or the same time as Europe, so not in spring.
