Where is kyogore in pokemon heartgold?

Answer 1

it is in the hidden tower
After you've beaten red at mt silver you speak to mr Pokemon and he gives you a blue orb (red for soul silver) he then tells you where to go and you go there (it's on the route leading to the safari zone) when you get there kyogre will be there. Once yo have caught him you speak to him again (or prof oak I can't remember) and he tells you that if you catch a groudon (kyogre on soul silver) he'll tell you the rest of the hoenn myth. On heart gold you can't catch groudon (without cheats) so you have to trade one from soul silver (vice versa for soul silver) and once you do that and sshow it to prof oak or mr Pokemon he will give you a green orb and you can go back to the embedded tower (where you caught kyogre/groudon) and catch rayquaza
