All of my Godzilla 2014 theories in one

Alright, so, like most of us here, I have several theories about plot details of the upcoming movie, and I've decided to post all of my guesses based on the clues we have so far in one thread. I'm not going to bother with explaining the reasoning behind my theories, since this is going to be long enough as it is, but if anyone wants to know why I made certain guesses, I'd be happy to elaborate in a reply. Obviously this will only paint an incomplete and probably very inaccurate picture of the events of the film, but this is as much as I was able to reasonably guess with the information I know.

Our story starts circa 65 million B.C. when a giant meteor impacts in what is now the Yucatan Peninsula. Little did the paleontologists who would later study it know, this meteor contained massive amounts of some radioactive element which was spread all over the Earth by the impact, raising the radiation levels on the Earth's surface to over 10 times the natural level. This, of course, along with the climate change caused by the impact, wiped out most life on the planet, and the surviving species were forced to adapt to the radiation, darkness, and cold.

Some species did this by, rather than becoming resistant to or avoiding the radiation, feeding on it. They slowly became like living nuclear reactors, absorbing the radioactive elements in the air to fuel the reactions inside their bodies, which grew to incredible sizes in order to contain the energies they produced. In order to support their weight, their bones, muscles and skin were replaced with much stronger materials, which made them extremely durable as an added bonus. These monsters did not need to eat or breathe because they produced all the energy they needed themselves, although they did kill and eat each other in order to absorb their nuclear power and still had methods of respiration (e.g. lungs and gills) so that they could take in the radioactive elements into their bodies.

Perhaps the mightiest of the monsters were the Godzillasaurs, which evolved from semi-aquatic, freshwater-dwelling dinosaurs that, like crocodiles, escaped the K/T extinction due to their amphibious lifestyle. These powerful beasts had nearly impregnable hide even by monster standards (as well as, possibly, regenerative powers) and could release the energy of their nuclear reactor stomachs as a breath weapon of incredible heat. The only other monsters that could threaten them were the species of the mysterious "ancient foe" mentioned in one of the toy descriptions - which I will refer to as the GKM (Godzilla Killing Monster) from now on – which, unlike the other monsters, did not have to kill and eat its prey to absorb their radiation, and could instead drain it directly from them with some kind of stinger or proboscis, which would result in the victim's death. These often hunted Godzillasaurs due to their massive power.

Eventually, the monsters depleted nearly all of the radiation left over by the meteor, causing most of them to die off. However, some of them survived by going into hibernation deep under the sea or in massive cave systems, where they slept undisturbed for eons.

In 1954, Godzilla, who is possibly the only Godzillasaurus to have survived by going into hibernation, is awakened by the Castle Bravo H-bomb test, and the US military, of course, decides that they might as well use one of the nukes they're testing to kill him. It doesn't work. Being understandably a bit freaked out now, the military panics and makes several more attempts to nuke him, culminating with an H-bomb being dropped directly onto his head and still having no effect... well, no negative effect, anyway. The massive amount of radiation he absorbs from all those nuclear blasts causes his atomic breath to become incredibly powerful, and possibly boosts any regenerative abilities he may have. After rampaging through the Marshall Islands (causing them to become contaminated despite the radiation from the nuclear blasts being absorbed), Godzilla returns to the sea to hibernate once more.

Not long after this, another nuclear test awakens one of the "Mutos" sleeping in an elaborate cave system under the Nevada desert. This monster is successfully killed by another atomic bomb, and the M.U.T.O. Research Facility is established to study the Mutos as well as monitor them to make sure they stay underground. Over the next few years, several of the nuclear "tests" in this area were really Mutos that escaped the facility being put down.

In 1999, Godzilla is again awakened from his slumber when he is attacked in his sleep by the GKM, which is attracted by his massive levels of nuclear power. It manages to drain some of his energy before he escapes and seeks out a source to replenish the small fraction of his power he lost (he gets kind of greedy after gaining so much power from the nuclear tests) This brings us to the beginning of the actual film (it took long enough!), as Godzilla attacks the Janjira nuclear power plant, where Joe and Sandra Brody (Bryan Cranston and Juliette Binoche) work. Sandra is killed by a radiation leak, and Joe witnesses Godzilla himself, but no one believes him due to the US government covering it up. These events cause him to hold a grudge against both Godzilla and the government.

By 2014, Dr. Serizawa (Ken Wantanabe) either runs the M.U.T.O. Research Facility or is an important scientist there. At this time, something, possibly the testing of some anti-monster superweapon invented by Serizawa, causes the Mutos to break out of the facility en masse and proceed to ravage Las Vegas. The military attempts to kill them off without nuclear weapons, but they are fighting a losing battle, as although they are not completely immune to conventional weaponry, they still take a while to bring down that way and are quickly breeding out of control. The presence of a few flying individuals complicates things further. Pretty soon, things start to look hopeless for the Southwestern US.

Meanwhile, the GKM and Godzilla have been playing cat and mouse for the last 15 years. At around the same time the Mutos attack, Godzilla surfaces at San Francisco and proceeds to progress inland, destroying the city in the process. Being already well acquainted with the indestructible beast, the US military decides to send in paratroopers, one of them being Ford Brody (Aaron Taylor-Johnson), to use flares to lead Godzilla to the Mutos so he can curbstomb their puny grey a*ses. In what would be a big twist for the unsuspecting audience (which I just ruined for you if I'm right), the GKM emerges at the same place Godzilla did at around the end of the second act and takes off in hot pursuit of Godzilla.

JESUS, that was long! Well, that's as far as my theories go. Like I said, they are quite incomplete, as they mostly only cover the backstory and the beginning of the movie, and don't take into account the roles that Hawaii or Elizabeth Olsen's character play at all. What do you think of them?
