The battle resort Pokemon center talk to the people in there
No,He is a Generation 4 ( IV) Pokemon
You don'tAn IV checker is a fan-made appliance, and can be found online.^silly nub, you need to give him a link!http://www.metalkid.info/Pokemon/OnlineProgram/Calculators/IV.aspxhere you go, that's the best one around at present ;)
Darkrai is a Pokemon from Generation IV, and Pokemon ruby is a game from Generation III , so you can only get darkrai in Pokemon Platinum, Diamond or Pearl
Burmy is a Generation IV pokemon, and is therefore unavailable in the earlier games.
As of Pokemon Omega Ruby and Pokemon Alpha Sapphire, you can take Staraptor to the Move Tutor in Battle Resort and teach it Sky Attack. For Generation IV, you can teach Staraptor Sky Attack from the Move Tutor in Pokemon HeartGold and SoulSilver.
You can catch Seviper in Ruby, Sapphire, Emerald, HeartGold (IV), SoulSilver (IV), Black and White.
Manaphies are unobtainable in Ruby as it is a Generation IV Pokemon.
there's Pokemon Sapphire Version, Pokemon Diamond and Pokemon Pearl
You can't get a Regigigas in Sapphire, Ruby or Emerald. Regigigas is a Generation IV Pokemon, and Sapphire, Ruby and Emerald are Generation III games.
There is no TM68 in Ruby/Sapphire/Emerald, so this is in the wrong Category. For Generation IV (ie Pokemon Diamon and Pearl), TM68 is Giga Impact
Rumors of a possible confirmation of a remake to the games Ruby and Sapphire had been leaked around the web for awhile now so it's quite possible but don't get any hopes up as the current project for Gamefreak is Generation IV or Pokemon X and Y versions.
No, you must poketransfer from generation IV (it can be found in HG/SS but look it up to how to find it but the other rayquazas must come from sapphire/ruby/emerald so you gotta migrate that to Generation IV)
