What Godzilla's Ancient Enemy Really Could Be.

Hey guys, this is my first post ever here and I've been catching up a lot on the awesome news and leaks on this site. Please allow me to give my take on the ancient enemy that Godzilla appears most likely to
be facing in the movie based on all the hints so far.

If we look at some excerpts taken from details of the recently outed Giant Godzilla Toy Package, it describes Godzilla as, 'Possibly the last of an ancient species of giant amphibous creatures that evolved at a time when the surface of the Earth was over ten times more radioactive than it is today. Rarely seen but spoken of in ancient Pacific Island myths, 'Gojira' was last spotted in 1954, when the U.S. Navy encountered and attempted to kill him with an atomic blast in the Pacific Ocean. Since then, the giant creature has been living in the deep ocean - until a threat to his survival from an ancient foe forces him to reappear.'

If you take note of the two sentences I highlighted above, first we now know that the amphibious species belonging to 'Godzilla' thrived on areas of high radioactivity in the Pacific region. As the conditions of Earth changed dramatically over the years with radioactive levels plunging, species that cannot adapt either die out or go into a state of hibernation. It appears that Godzilla went into a state of hibernation, and was encountered by the US Navy in 1954 during military exercises. Clearly frightened by the immensity of their discovery, (in their ignorance) decided to unleash their nuclear arsenal on the monster in the hopes of killing it, which they later guised up as nuclear tests being carried out. Of course, the radioactivity from the nuclear bombs were unable to kill Godzilla, but these explosive 'tests' were sufficient to drive Godzilla deeper into the ocean to evade these attacks, which had since disappeared from man's sight.

While the US navy was aware they were unsuccessful in killing Godzilla then, (as Ken Wantanabe a.k.a Daisuke Serizawa in the movie describes that 'they were trying to kill it'), the US also made the
move to seal off access to these Pacific Islands to ensure nobody else would ever encounter Godzilla which had disappeared into the ocean. How do we know this took place? If we look at real-life history,
fallout from the detonation of Castle Bravo in 1954 —intended to be a secret test—fell on residents of these islands and news spread quickly around the world. The islanders were not evacuated until a few
days later and suffered radiation sicknesses. They were since never allowed to return to the islands as the US classified the area to be unsafe.

Next we focus on the threat to Godzilla's survival, which is described as an ancient enemy that 'forces Godzilla to reappear'. This enemy would also have been thriving during ancient times on high levels of radioactivity to survive, just like Godzilla, and also disappeared when the conditions changed. It therefore appears that this ancient enemy living in the ocean was also awoken by accident by the radioactivity of the nuclear tests in 1954 which was not known by humans. For something to drive Godzilla out from the ocean and back onto the land surface for survival, this enemy would have been based in the ocean too and have the ability to snuff out something from Godzilla that threatens the very existence of Godzilla. And what is that ability? - The parasitic ability to absorb / leech the radioactive energy from Godzilla's body. This would make sense because if you look at the storyline, Godzilla first surfaced onto land on the other side of the Pacific, Tokyo ( to feed on the radioactive energy), causing the destruction of the nuclear plant which was covered up as an accident. 

How do we know the enemy is based in the ocean too? - Bioluminescence, which is used by organisms living in dark depths gives us a strong hint of that, if you look at the glowing body of the MUTO creatures. But that's not to say the eight-legged MUTO monster or Flying MUTO you see in the trailers comes directly from the ocean. They are merely products of M.U.TO's cross-experiments between existing animals and the cells of the ancient organism which have the ability to leech on Godzilla's radioactive energy. How do we know that? In Legendary's description of the movie, it states that Godzilla is pitted against malevolent creatures who, bolstered by humanity's scientific arrogance, threaten our very existence. In other words, the ancient enemy of Godzilla appears to be a micro-organism based in the ocean that thrives on radioactive energy, similar to how algae or krill if uninhibited in growth would decimate oxygen levels that kill fishes in ponds and in the sea. Therefore Godzilla is forced to come out of the ocean because the micro-organism that has been revived by the nuclear tests in the Pacific ocean is leeching on Godzilla. Humans, who are unable to destroy Godzilla (which is now on land) using nuclear bombs, decide to mutate the micro-organism's cells to turn them into land creatures thinking everything is under their control only to find it go heywire, creating a whole new set of monsters that threaten not only Godzilla but humans themselves too.

This leads me to conclude that the ancient enemy Godzilla is facing is similar to a new version of Destroyah but it would not go by that name and would be a new adversary altogether. If we look at Destroyah's origins, it originated as a colony of Precambrian crustaceans that had been awakened and mutated when the Oxygen Destroyer was detonated to kill the original Godzilla in 1954. After it's detonation, the energy released, revived, and mutated the Precambrian crustaceans that lay beneath Tokyo Bay. Destroyah grows quickly and adopts several appearances from his microscopic form, 3-mm form, insect-sized form, 2-meter form, 18-meter crab-like forms, a larger aggregate crab-like form, a bat-like flying form, and a bipedal 120-meter, demonic final form.

In comparsion to the new Godzilla film, nuclear bombs were in use this time round in an attempt to kill Godzilla in 1954. If you add on the presence of the 8-legged MUTO and the flying MUTO including other smaller-sized MUTOs that will be present in the movie, it further points to the plot of Godzilla facing a Destroyah-like enemy. Perhaps Gareth Edward's comments that audiences will be wowed by something else present in the movie to confront Godzilla refers to the final-form of this Destroyah-like ancient enemy?

What do you guys think? :)

Update: While we are still unclear of the exact storyline and everyone is coming up with their theories on the origins of the MUTOs etc, it seems more hints have been outed by Gareth Edwards in his interview with Verge.

I understand that while there were people who find my theory on the MUTOs and Godzilla plausible, there were others who dismissed it altogether, especially on the part where I said Godzilla may have been leeched on by a micro-organism in the ocean which was later on mutated by cross-experiments by scientists on land which went out of control.

In the interview, G Edwards talked about the design of the MUTO monsters, where he said they were designed in such a way that when people looked at them, they could see that it was ' evolved from the same organism'.
