You catch Kyogre AND TRADE A GROUDON FOR ANY POKEMON BUT KYOGRE go to the Pokemon proffeser he will give you an orb where you can catch raqausa.
You have to transfer from HeartGold or SoulSilver.
in heartgold/soulsilver you go to the embedded tower after you get the jade orb
trading
it depends what level if it is LV 100 keep it and catch more pokemon, but if it's only lv 70 i would say start over and then get rayquasa later
first get a kyogre. then beat the elite four 1-2 times . then go to pacidifilog town. then go east and then north. there will be a tower. complete the maze and you will reach rayquasa.
There is no best Pokemon on Pokemon HeartGold.
The most powerfull Pokemon in Pokemon ruby i think is Groundon,SAphire Kyogre,Emerald RAyquasa??
there is no Pokemon Mansion in Heartgold.
They are not in Pokemon HeartGold
where is the pokemon transfer lab in heartgold
No, but you can trade Pokemon only in HeartGold to Black
Aura Beam is in Pokemon HeartGold.
