All those tanks, planes, ships, and missiles reminds of the old classic Godzilla movies where they try to hit everything they got at him. BUT that makes him a bad guy and I rather like to think of him as a good guy fighting other giant monsters for sake of mankind.
G is a antihero, he will fight the bad monster but that doesn't mean that he is all about helping. I mean just him walking around is a destructive act due to his size.
Godzilla, Mothra and King Ghidorah Giant Monster All-out Attack, I think frames it nicely as it has Godzilla on a rampage and Mothra, Ghidorah and Baragon try and stop him
The plot has the three monsters Mothra, Ghidorah (normally a bad guy) and Baragon as Guardian monsters meant to protect Japan. The thing is in the plot Godzilla is also a Guardian monster. These Guardians are sorta powered by spiritual power. But as the plot progress its pointed out that Godzilla is in this interpretation the spiritual will of the victims of Japan in the second world war well the other three are more the nature and Ideals of modern and ancient Japan.
I think you might like that version Equation as G is the manifestation of anger against historical events of The Imperial Japanese or rather the Guilt of that heritage clashing with Modern Nationalism (Ghidorah), historical Heritage (Baragon) and the want of the ideals of the modern (Mothra) with the needs of a modern nation to move ahead (JSDF).
As a guilty conscience of not just the Japanese but basically all humanity Godzilla occasionally is going to show up and show you what you have done.
