rayquaza on top of sky pilair, regirock in the desert, groundon in the cave of origin
Sadly, no. The creators of the game forgot to add in the Pokedex, so trading is impossible without GameShark. :(
go to your home and you will find them waiting for you at your door
you can find the legendary Pokemon regirock
Tornadus, Landorous, Reshiram, Virizion, Terrakion, Cobalion, Kyurem, and Victini.
The starters in ruby (like sapphire) are: Torchic Mudkip & Treecko In ruby, instead of getting the legendary Kyogre, in the story line you'll find Groudon.
if you want to cheat to get all legendary Pokemon on ruby you have to play on the computer
No, EX Pokmon do not count as basic Pokmon in the Pokmon Trading Card Game.
the Sapphire and ruby plates in leaf green are two plates that you have to give to celio to be able to find one of the three legendary dogs.
You can find 6 legendaries: Groudon, Latios, Regice, Regirock, Registeel and Rayquaza
No.
Well you can't find them all in 1 place ,but all I know that is its up to the 4th gen
there are several islands that can be found after the game is finished. You can get there through the ports if you get the specific ticket.
