They are in both, so don't panic. :)
Breed a Pokemon from your game from one from a different country (like japan). The egg ill be about three times as likely to be shiny then just looking for one in the wild.
You cannot get the Legendary Dogs (or Beasts such as Raikou, Suicune and Entei) in Ruby without either trading for them or cheating for them because they are not available in the wild in Ruby in any way, shape or form. But you can catch it in Pokemon Ruby Destiny-Reign of Legends. But in the original Ruby or Sapphire you can't get it.
The Fighting Dojo Master is in Mount Mortar in the Johto Region. There are three entrances between Mahogany and Ecruteak, so take the middle entrance (and have rock climb and surf) to get to the dojo master.
There are no seven Pokémon in Pokémon Crystal however there are six Legendary Pokémon in Pokémon Crystal, the first three Legendary Beasts are Entei, Raikou and Raikou and the other two Pokémon are Lugia and Ho-Oh. Celebi can also be found in the game but only through the use of the GS Ball item.
You can trade a Pokemon with the move dive from Pokemon Emerald, Ruby or Sapphire to HeartGold and SoulSilver and it will work.You can't, it's unobtainable.Dive is unobtainable in Pokemon Heart Gold Version and Pokemon Soul Silver Version as either a TM or HM. quote it is obtainable and to get it u need to go to the house near the battle frontier there be three dudes and one can teach u dive
Trade them from HeartGold and SoulSilver.
You don't, the three 'crown' Legendary Beasts are obtained via a wi-fi event for SoulSilver/HeartGold.
Nothing happens after that. You just caught the three legendary roaming Pokemon in the Johto Region.
By Ruby I'm assuming you mean the Hoenn starters, then yes, you can get one of three of them in HeartGold/SoulSilver
nothing, you just have three legendary Pokemon
yes you can also catch them in soul silver.
i think the way to beat them is through the mystery gift because you could get the level 55 legendary beasts there.
You chase Entei and Raikou across Jhoto and you catch Suicune at the top of Cerulean City.
You can get a level 1 Palkia, Dialga or Giratina in HeartGold or SoulSilver versions if you have an Arceus in your party. Enter the lone building at the Ruins of Alphs and an event will start where you get taken to Sinjoh Ruins. Talk to Cynthia where she will give you a choice between one of the three legendary pokémon from Diamond, Pearl and Platinum versions.
If by enti you mean Entei the legendary dog then yes, all three dogs are there.
yes i believe so
First, go to the Burned Tower in the Southeast. Then you see Morty and this guy named Eusine (a guy looking for Sucuine). Then you see your Rival and you battle him. Then you climb down a ladder then you see three Legendary Beasts. Then they will scram and now, you can return to the gym now.
