Yall do realize that Mecha G is Kevin, the left head of Ghidorah right? Thats the computer that runs it. Let's just ignore that tho for a sec.
Its hard to say Godzilla and Kong had been fighting literally night. The beam Godzilla shot at Mecha G was not anything close to what he had done to the hollow earth. So he wasn't 100%
Mecha G would brutalize Ghidorah in the Melee area seeing as how fast and he is almost as heavy. But his durability is suspect due to Kongs age. But its a supercharged axe? It should cut Ghidorah to right?
Kinda tough fight but I think Ghidoras durability, flight and gravity beams should wear Mecha G down.
If Mecha G and Kong switched I think Godzilla would have beat him honestly. So yeah, Ghidorah 6-7/10
Oh, I understand Ghidora's mind was the base for Mechagodzilla.
I don't think Kong can survive the beating Godzilla took against him. It was sheer luck he didn't have to, essentially being allowed to wail on him until he went down.
Yet Godzilla was knocked OUT by Ghidorah, while he essentially took the beating from Mecha like a champ. Even while tired.
I think Ghidorah has more power, far more durability from his healing factor, can fly, and has three independently targeting heads. Mechagodzilla should simply be overwhelmed.
I'm a Ghidorah fanboy through and through, but I'm not too sure about him winning here.
Mecha stomped both Godzilla and Kong at the same time right after brutally stomping Godzilla solo. Then he almost killed them both, but got interrupted right before a killing blow to Kong by the humans whiskey shenanigans leading into him being tag teamed. Mechas beam also completely overpowered Godzilla's, and there hasn't been any indication that Godzilla's beam was weakened or somehow finite. That argument seems like a people trying to make up an angle IMO.
Weakened or not, him flat out stomping both of them at the same time was impressive. On top of being physically stronger than Godzilla and tons faster? Ghidorah might actually be in for a pretty bad day. I'm not even sure Ghidorah's lightning beams could put Mecha down (maybe? since he's a robot? idk). If he gets in grappling distance, I don't see what's stopping Mecha from just tearing off the heads or eviscerating him pretty quick with that drill tail.
As of now, my ranking for the monsters in these moves are:
Mecha Godzilla > King Ghidorah > Godzilla > Kong (Mothra, Rodan, and the Mutos are all probably somewhere around Kongs level) > Skullcrawlers
Also, IDK about Godzilla being all that worn. He took the ax to the leg and chest (this was the big one that got him down for close to a minute) if I remember correctly, but got up after both no worse for wear. If anything, he seemed faster and more vicious after than big axe hit as he stomped Kong in their last fight. Other than that? Some punches from Kong that didn't even phase Godzilla.
Kong was in pretty rough shape, obviously. Godzilla? Not all that weakened.
