Nuclear Fission's Curse: The Kaiju Within

Prompt: Write a transformation story of a normal human reader being effected by the nuclear fission leaks, causing him/her to painfully (and agonizingly) turn into a kaiju version of himself/herself (while retaining his/her humanoid appearance), complete with mutation stages (causing extreme pain, making the reader shriek when mutating/rapidly evolving into a new stage of mutation, with the voice becoming more beastly and less human, sounding different in each form), massive growth, feralization (becoming more instinctive and primal in nature), and mind/mental change (making him/her lose the ability to understand human language and no longer could speak, as well as losing his/her self to a more beastly mind), with the reader rapidly mutating into another form in each 1-3 hours. The reader would terrorize and destroy any buildings in the city (or cities) in his/her former homeland, as well as causing fatalities to normal humans, making him/her a new threat to civilization. In the reader's first stage of mutation, the reader grows to being 50 feet tall (making his/her clothes rip off from his/her mutating body), the body thickens to support his/her changing size, develop a short tail, develop a fin on his/her back, the teeth in his/her mouth would start to sharpen (while still retaining a human face), the reader's privates and (if a female) breasts would disappear completely due to his/her mutation, and the reader would start to lose his/her mind and the ability to speak, becoming a hyperaggressive monster in a process. In the reader's second stage of mutation, the reader grows to be 140 feet long (on his/her belly due to being unable to be bipedal), the reader's body growing fatter and stronger in this form, the reader (in this stage) loses his/her ability to walk on his/her legs (causing him/her to only able to crawl/slither on the ground), the arms shrink into useless stubs, the eyes become dead-looking soulless eyes without visible irises (making them resemble fish eyes), the scales start to grow all over his/her body, the tail continues to lengthen, and the reader completely lost all human memories, personality, and language, being now a beast. In the reader's third stage of mutation, the reader grows to being 260 feet tall (having regain his/her ability to go bipedal), the reader regaining his/her ability to walk on his/her legs, the arms growing back as small appendages (but now with paw-like hands with clawed fingers and an opposable thumb on each hand), the reader becoming less fat but still growing stronger, the tail lengths even more and finally becomes a thick and scaly tail resembling that of a lizard or a crocodile to help balance his/her now-monstrous body, the reader experiencing hair loss all over his/her body except on his/her head, and the reader now makes kaiju-esque roars, growls, snarls, and shrieks. In the reader's fourth stage of mutation, the reader grows to being 429 feet tall, the reader's eyebrows become thicker to partially obscure his/her eyes (making them less unsettling-looking but still terrifying), the arms growing larger with more functional clawed hands, the reader's face becoming more gnarly-looking with his/her teeth becoming more disorganized and growing tusk-like canine teeth on the lower jaw as well as fangs being grown from the upper jaw (while still retaining a humanoid jaw-structure), the reader completely losses all hair on his/her body except a few strands of hair on his/her head, the scales thicken to protect his/her colossal body, and the bony plates (resembling those of a stegosaur dinosaur from the Mesozoic) growing on his/her back. Here is the kaiju reader's personality; in stark contrast of his/her formerly human self, the kaiju reader is outright detached from everything emotionally, so much that he/she ignores military's attempt to injure him/her as he/she slowly yet methodically shambles his/she way through human populates. The reason of this could be either due to him/her being either a mindless force of destruction or worse, in a constant state of pain, agony and suffering from his/her mutation and disfigurement, fitting the description that the kaiju reader "is equally a victim of the nuclear disease". The kaiju reader's zombie-like demeanor eventually cracks as soon as American B-2 Stealth Bombers dropped Massive Ordnance Penetrator (MOP) that injures his/her back and blasted off one of his/her developing dorsal plates, enraging him/her that he/she unleashed his wrath upon his/her attackers and surroundings alike. The kaiju reader also has a degree of intelligence during combat situation; in addition of developing ESP ability to protect his/her dormant form, the kaiju reader developed his/her tail beam attack as the alternative to equally destructive yet energy-taxing dorsal beams and even reserved some energy to surprise attack the squadron of workers who attempt to inject it with a coagulant. Here are the kaiju reader's abilities; Physical Adaptation (having the capacity to develop new features and powers through controlled self-mutation in order to adapt to any situation in short amount of time, something which made possible thanks to his/her genetic information which 8 times of normal humans' own), Extrasensory Perception (he/she possesses a "phased-array radar" which allows him/her to detect threats without even needing to see them, the kaiju reader utilizes this to sense his/her enemies' presence either when hibernating or in combat, this explains how he/she can destroy drones that went too close in observing him/her when hibernating and direct his/her dorsal plate beams' direction straight to oncoming foes behind him/her so he/she won't waste too much energy just to attack them. The same ability also allows him/her to fire small bolts of atomic energy to shot down drones sent to study him/her within range), Atomic Breath (just like the fictional character Godzilla, the kaiju reader possesses the ability to fire atomic breath from his/her mouth with the glow of his/her dorsal fin acts as the sign of him/her about to use it. It also showcased both how he/she develops such ability and subsequently refined it; the breath at first projects in form of a powerful cloud of radioactive black ashes that can quickly spread through the city before being heated up into a thin purple beam that could slice through buildings, igniting the already spread ashes into deadly inferno), Dorsal Plate Beams (Upon sensing multiple American bomber aircraft began to approach him/her, the kaiju reader redirects his/her charged atomic energy beam onto his/her dorsal plates, and project it in form of a salvo of atomic beams to dispatch them. He/she would also use it in conjunction with his/her extrasensory perception ability to shoot down drones that approach his/her comatose body and multiple drones that attack him/her. While devastating, this ability greatly consumes much of his/her energy reserves that he/she had developed atomic tail beam as better alternative after using it twice), Atomic Tail Beam (To get around the fact that his/her dorsal beam attack spent much of his/her energy reserves, the kaiju reader redirects some portion of atomic energy to his/her tail and projects it in form of atomic laser that fires from the mouth on the tip of his/her tail. This, when used alongside atomic breath, enable him/her to cut and slice through multiple adversaries from every direction at once. The kaiju reader uses it to conserve his/her energy better to take down drones that approach him/her), and Superhuman Physical Attributes (The kaiju reader's intelligence is not as pronounced as his/her formerly normal human form, yet evident through his/her prowess in developing new abilities and other features via aforementioned physical adaptation each specifically to overcome certain situations. The creature developed durable hide in order to shrug off the military's assaults since he/she apparently foresaw greater resistance since his/her first rampage; he/she only developed his offensive abilities once the military finally managed to injure him/her. The fact that he/she developed ESP ability to take out drones and other threats which got too close to his/her dormant form following the destructive demonstration of his/her newfound atomic breath and dorsal beams indicates the kaiju reader being fully aware with the fact that spending too much energy from using them for the first time would render him/her vulnerable. The same goes to his/her tail beam ability which has better angle and less energy consuming than the more devastating yet less practical dorsal beams as well as the ability to quickly replenish his/her energy reserve just enough to quickly recover when the military attempts to force-feed him/her with blood coagulant to freeze up the kaiju reader's body, showcasing his/her capacity to learn from experience despite still outsmarted by normal humans). There should be quotes from the characters (including but not limited to the reader) in this story so we know what they're saying and what they're thinking. Also, it is a POV reader story, so it should not be in an author's point of view (my, I, mine, etc), and it should be from the point of view of the reader (you, your, etc).
