We all know the movie is focusing on the epic (and I mean EPIC!) battle between two of the most prominent kaiju in all cinematic history, but the whole story is yet to be told. We’ve only seen the tip of this colossal iceberg and there’s plenty left to speculation. So as we wait (finally!) for it’s long-awaited release in March let’s run down a few of our theories.

MECHAGODZILLA!
Let’s get the most obvious out of the way. Given just a brief glimpse at the beginning of the trailer we see what could be none other than Mechagodzilla.

Watching this scene over and over again it really does leave little else to be argued. It has the shape of Godzilla but appears mechanic and we’re given the briefest glimpse of an orange-glowing energy pulse in the thing’s neck.
Unless Godzilla levels up his atomic flame from blue to reddish-orange, similar to what happened during the Heisei era, we might be seeing none other than Godzilla’s mechanical nemesis.
Reasons for this theory.
By the trailer we’re told that Godzilla is out there hurting people. Now that’s a big turn of events given how Godzilla has been the earth’s defender and a hero to humanity. Although, the somber ending of Godzilla: King of the Monsters does reflect that Godzilla is on our side ‘for now‘ leaving room for a frightening possibility of Godzilla becoming our destroyer.
What could turn him against us? Now that’s the question.

Perhaps it’s our meddling with the Titans – genetic engineering or bio-experimenting – that pisses Godzilla off. After all he is their king and would only be protecting his subjects from us if that were the case. And you know it’s entirely within reason that people like Alan Jonah (Charles Dance) would be using Titans as his own personal weapons.
That could be enough to send Godzilla into a shit storm of fury. I don’t think that’s entirely the case though. If we are indeed getting Mechagodzilla in this movie then it’s possible Godzilla is not, in fact, to blame for these sudden attacks at all.

You see, back in 1974, when Mechagodzilla was first introduced he appeared as Godzilla at first, albeit a counterfeit. Just like the Terminator has a fleshy exterior to hide the monstrous T-800 underneath, Mechagodzilla wore a Godzilla skin suit to conceal his true identity while leaving a trail of destruction in his wake and the blame being pinned on Godzilla.
So what if what we’re seeing is not the real Godzilla but an imposter? Someone whose sole purpose is to create chaos and drive humanity to the brink of despair? In desperation, humanity would turn to the King of Skull Island to battle the King of the Monsters and hopefully end the sudden reign of terror.

While Kong and Godzilla are busy beating the shit out of each other the world would be left defenseless against whatever the true threat operating behind the scenes is.
I can see this as being a likely case. We know Alan Jonah is still very much active out there. We also know that he had some sort of plans for that (SPOILERS!) discarded Ghidorah head in that post credit scene. Hmmmm. (We’ll visit this plotline a little later on. )
Could Jonah be orchestrating events so earth’s two mightiest Titans fight to the death while leaving the planet open to advance his master plan? This does strongly echo the original intentions of Mechagodzilla.

Given that Legendary has been faithfully adapting classic motifs from Toho’s Godzilla mythos it makes sense to see Mechagodzilla finally given their extraordinary treatment. Mechagodzilla is renowned as one of Godzilla’s chief villains and became an instant fan favorite upon his introduction back in 1974. Also he is one of the few Godzilla kaiju to make an appearance in all three of Toho’s Godzilla eras, just like Mothra and King Ghidorah.
Kevin’s Head
Kevin’s head is still a mystery. Why did Jonah want to purchase it so badly? This could be another connection to the Mechagodzilla theory. In the 2002 film Godzilla Against Mechagodzilla, a film rebooting the original concept, Mechagodzilla is made from the bones of the original Gojira. Let that sink in a little.

So in that film there are two different Godzillas: the original Gojira – who died by oxygen destroyer – and another who was the current Toho Godzilla.
Humanity builds Mechagodzilla around the bones of Gojira to fight Godzilla. That’s just all kinds of Hell yeah!

In that film Mechagodzilla was biomechanical and at one point the DNA of Gojia’s bones activates, takes over, and goes insane.
Could it be the decapitated Ghidorah head (lovingly known as Kevin) serves as a kaiju DNA structure for Mechagodzilla? Or…is there someone else we could be seeing?
Mecha-King Ghidorah
Anyone familiar with 1991’s Godzilla vs King Ghidorah will know exactly what I’m talking about. In that colossal movie Godzilla promptly takes down Ghidorah but the battle is far from over. From the discarded body humanity builds the Mecha-King Ghidorah!

This mechanical beast is mankind’s only hope against the devastation of Godzilla.
Given that, at the end of GKOTM, there’s still that remaining piece of Monster Zero, and the fact that they purposely show it to us, it’s a good bet someone has some wicked plans for it.

It’s entirely possible that Jonah’s team builds Mecha-Ghidorah out of that head.
So would fans rather see Godzilla battle Mechagodzilla or Mecha Ghidorah? Fuck I’d hate to choose between the two. I’d be thrilled to see him and Kong fight both! Bring it on!!!

And Legendary could make that shit look great!
So either Mecha is a possibility at this point.
Could this severed head be the missing piece to the puzzle? The unseen force working in the shadows by a skilled puppet master to bring an end to the known planet?
Destoroyah!

What if Legendary is planning something even bigger? Something less obvious? Something that embodies destruction itself? I mean would it be that far of a stretch for Legendary to bring in the Devil of Godzilla’s mythos to challenge the two Kings?
Think about it. Once again we point to Ghidorah’s rotting head (I swear there’s more to that thing). Let’s recall how Ghidorah lost that head: it was during the ocean battle with Godzilla, and Godzilla bit the head clean off. Then immediately afterwards the oxygen destroyer struck the both of them and left its carnage upon the waters.
In Gojira, this was the very weapon the slew our beloved monster. Then, during the Heisei era, the oxygen destroyer was brought back to fans’ memories, for out of the debris and mutations left behind from the OD a new and terrible force came into being: Godzilla’s most terrifying enemy, Destoroyah!
So…why would Legendary bring in the oxygen destroyer? And that thing not only hit Godzilla but also Ghidorah and the severed head. The same head seen at the end of the credits, letting us know it’s still of importance.
What if the cells of the head are crawling with radiation that could lead to Destoroyah’s emergence into the Monsterverse?

Destoroyah could be a new monstrosity grown from Ghidorah’s own cells, have prescient memory, and, along with that, an inherent hatred for Godzilla. Yes, I’m suggesting Keven could become Destoroyah.
During the movie Godzilla vs Destoroyah, Destoroyah was unique for the fact that it went through various evolutionary stages until reaching its final form.
What if whatever Jonah’s monster eventually evolves into this thing? That would be one helluva final form and final battle. It would be something beyond Kong or Godzilla’s ability to face alone. I can see them having to join together to defeat the power of Destoroyah.

After all, they’ve already hinted at Godzilla vs Destoroyah by introducing burning Godzilla at the end of GKOTM. Could it have been a hint of more things to come?

So those are my theories, at least for now. As more is revealed I’ll be sure to make a follow-up post. Maybe none of these are right. Maybe Gigan will be the big reveal! Or, better yet, Gamera shows up and beats them both into submission. I’d be down for that!
There’s still room for the Super X to make an appearance as well as other beloved kaiju. We’ll have to wait until March to know what all is in store for us.
It’s an exciting time to be a fan and I hope you share your thoughts and theories with us in the comments below. Thank you and long live the King!
