its running around wild after you talk to it in burned tower.
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.
You'll see Raikou and Entai in Ecruteak Town, in the burned tower. After that, they just wander.
If Raikou faints, go to the Burned Tower . Then you see him. Same as the other legendary dogs however Raikou will only regenerate if you defeat the Elite 4 and Lance, once you have caught Raikou, it will no longer regenerate.
Raikou wanders around the maps (including the Sevi Islands) after you beat the Elite Four when your starter was Squirtle.
After you defeat the elite four, Raikou and Entei run around Johto. (Suicune can be captured in Kanto.) Your first encounter with Raikou is completely by luck and chance, but once you see raikou once, you can keep track of what area it is in. again, Raikou can be found in every route in Johto, but he changes location each time you enter a building, go to a different route, or enter a city.
There is no real way to get Raikou to come to you. You have to keep trying to get to Raikou. It is lucky if you encounter Raikou.
raikou
Raikou has no specific place in Kanto - he is found randomly throughout the land. However, you need to have started your Pokemon journey with a Squirtle if you want any chance of encountering it. Remember, you must defeat the Pokemon League first, before you can see Raikou.
after meeting entei,raikou,and suicune in the burned tower in etrueck city, entei and raikou will be running all around jonto at lv. 40 . you can check your pokegear to see where they are.
Then he or she is the luckiest person to play that game. I'll try and see if it's a glitch.
