If y’all don’t understand why he hates muto prime so much it’s cause in the comic “Godzilla Dominion” The muto prime killed a godzilla species named “Dagon” by stabbing to sperms into him and injected eggs in Dagon weakening him and slowly killing him as the baby muto’s hatch and eat Dagon from the inside out. (Bonus Dagon is the Godzilla today’s father)
That's where you are wrong there. Muto Prime wasn't in "Godzilla: Dominion". That comic took place after "Godzilla: King of the Monsters". Muto Prime was actually in a different comic named "Godzilla: Aftershock" in which it's events took place after 2014
Fact that Godzilla in Godzilla versus King Kong when they were fighting in Tokyo for Godzilla, it wasn’t even a fight. It was like him playing with a toy playing with a kaiju toy. Kong literally shoved a piece of Godzilla’s inside of his mouth, and he was not happy about that
