Kong killed Mecha G. He delivered the final blow and chopped off the head. Kong had helped, but he was the one that physically did the act. It was the least he could do after Adam decided to make Kong fuckin useless against Godzilla in a movie called Godzilla vs Kong. Like how do you introduce an anti-Godzilla axe and have it not seriously damage Godzilla when it hits him in the head? Why make Kong need help every fight when you build him up to be this alpha Titan that is going to finish a war between their ancestors. The next director better show Kong to be a beast like he always was and I don’t want to see a human anywhere near those fights. Kong handles his own fights and always has.
