It's really hard to say. Godzilla has his atomic breath and great strength, but King Ghidorah has three heads and can fly. In a straight - up fight, if Godzilla can get in close and use his physical strength, he might have an advantage. But if King Ghidorah can keep his distance and use his aerial attacks and energy beams from all three heads, he could be the victor.
One idea could be a story where Godzilla and King Ghidorah have to team up against an even greater threat from outer space. This would force their natural enmity aside as they realize the common danger.
It's hard to say. Godzilla has his powerful atomic - breath which gives him a huge advantage. But King Kong is very agile and intelligent. So, it could go either way depending on the circumstances of their fight.
