raikou cannot be caught on Pokemon ruby
You can't find raikou in ruby.
no!! of cours yo can not catch raikou in ruby raikou can only be cought in the johto region
YOU can only get raikou by migrating it from old Pokemon game boy advance games pokemmon ruby and sapphire
Entei, Suicune, and Raikou are not available in Pokemon Emerald, Ruby or Sapphire. They can be brought into the game by trading.
You'll see Raikou and Entai in Ecruteak Town, in the burned tower. After that, they just wander.
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.
It means you have not seen it, but if you have you should also see Entei n the map, if you see Entei but not Raikou it means that Raikou is currently on the same route as you.
By the way, they are the legendary cats, not dogs. The Pokemon Company revealed that Raikou is a tiger, Entei is a lion, and Suicune is a cheetah.
Me too, i came to that place but nothing was there, i have catched raikou already
suicune is a rubbish Pokemon, if ya want it its not in emerald, its in Pokemon silver gold ruby and sapphire, ( they got rid of entei raikou and suicune to make way for rayquaza )
to catch Pokemon you have to obtain raikou palls
