How do you catch Kyogre in heartgold without a masterball?

Answer 1

To catch kyogre without masterball buy 20 ultraballs and 1 healball and go to the embeded tower if u have blue orb you can go if you don't you cannot go because you need blue orb to catch kyogre then if ur fighting kyogre use healball first before the ultraballs if the healball fails to catch use the ultraballs but you need to attack kyogre before you can catch it i use hydrocannon on kyogre and his hp is red and i use my ultraball and i capture it

Hope This Helps
