Godzilla Vs. Biollante (Alternate Take) - Subtitled

Prompt: Write an alternate take to Godzilla vs. Biollante, a film about kaiju (superfauna) monsters. In this plot, this is a completely different take to the story; it is July 25 1989, and Zilla (a dinosaur-like marine iguana kaiju from the "Godzilla" 1998 film) fights against swarms of Skeetera (giant mutated mosquito kaijus) in Florida and steps on some, but Zilla unintentionally causes the mutagen leaks into Shelter 54 (after stepping on the Skeetera queen), causing the flood of mutagen to spill into the shelter (due to the shelter's inadequate safety) and drowned the people (who had screamed in horror and pain) and the lab-grown plants in it, making the 15 people in Shelter 54 presumably dead. That is, until the military 5 days later discovered Shelter 54 in ruins and devastation, where the military had discovered that all 15 people from Shelter 54 had grotesquely merged together and fused with mutated plants, assimilated into a single massive organism (save Erika). 5 days later, on July 30th 1989, just after the mutant plant entity (formerly Erika and other human victims of Shelter 54), now known as Subject 19, is relocated to a secret laboratory in Japan, Dr. Shiragami has a conversation with Erika (in this mutated state) through special infrared machines that functions based on eye movement and muscle movement, revealing that Erika and all other former humans (who still had vaguely human faces in this stage albeit mutated) in this chimeric mass are in terrible pain, and Dr. Shiragami confirms that he'll help Erika and the other mutated former-humans. The plan seemed to work on October 22nd 1989, after Dr. Shiragami inserted Godzilla's G-Cells (for their regeneration ability G1) into Subject 19 as an attempt to revert the entity's mutation (unfortunately this fails and Subject 19 mutates even further, with Erika's eye and mouth being the last human thing in the mutant plant entity's body), which has taken a form similar to a rose and had grown beyond expectations. But on November 15th 1989, due to the mutation having become unstable, he cannot help Subject 19 (formerly Erika and other human victims) and says to Erika that she must continue to stay, thus engaging Subject 19 as it repeatedly says through the communication device "Kill me!" over and over (which is the last human audio from Subject 19), before it lashes its jawed vines/tentacles/tendrils at Dr. Shiragami before he escapes for his life. In the days that followed, Erika had fully merged with the rest of Subject 19 and is no longer able to be communicated by non-mutant humans, so Dr. Shiragami withdrew himself from social contact from everyone and dismissed his assistants for a holiday break. His request to euthanize Subject 19 has been rejected by his superiors, so, on the night of November 29th of 1989, Dr. Shiragami tampers with the containment controls to electrocute Subject 19 (as an attempt to kill Subjects 19 to end its pain and suffering), before he locks down the lab so no one gets into the lab (for everyone's safety) and he brings an industrial flamethrower from the inventory check as an attempt to destroy the lab and, in turn, finishing off Subject 19 (formerly Erika and other human victims), but he is then tracked by the security who then shoots him and kills him, unaware that Subject 19 (after growing exponentially) has released green smog (contamination), killing 112 non-mutant humans in the facility, before Subject 19 breaks out of the facility and escapes into the underground chasm it has formed, destroying the facility in the process. After escaping, Subject 19's roots have grown in a middle of Yokohama of Japan, with the city's citizens startled by the sight of Subject 19's new form (which continues saying "Help. Me" silently and completely inaudible to humans), as it wails as if in pain. The Japanese government orders Subject 19 to be destroyed, to stop its roots from expanding further into the city. Scientists who previously worked on Subject 19, cooperated to create a plan of attack against Subject 19 (by launching missiles at Subject 19's Erika's eye in the middle of one of its flowers). After the flowers collapse (the petals all fall off), aerial photography reveals that not only Subject 19 is still alive, but further mutating, developing into its next form called "Shin Godzilla" (or "Shin Gojira" in Japan), which resembles Shin Godzilla from the titular 2016 film (but with green skin and vines/tentacles/tendrils, including ones on its back and the one that extends and retracts from its tooth-jawed mouth), becoming mobile and able to walk on its own. The UNGCC then debuts the MBT-92 Maser Cannon (the newest arsenal in fighting superfauna threats) and targets it on Subject 19. While that's happening, the actual Godzilla (the ones from the 2014 film "Godzilla") appears and approaches Subject 19, but in a rare instant, Godzilla's immediate reaction is curiosity instead of aggression. Subject 19 then ensnares Godzilla and inserts the vine/tentacle/tendril from its mouth and into Godzilla's mouth. With Godzilla trapped, Subject 19 begins to extract G-Cells from him to further mutate itself, and it starts shooting out atomic breath (like Godzilla does, albeit from its back vines/tentacles/tendrils rather than from its mouth). Godzilla retaliates against Subject 19 and shoots his atomic breath and he smacks his clawed arms against its body before he decapitates Subject 19's Godzilla-like head, but Subject 19 is alive even without its head and it lashes its vines/tentacles/tendrils at Godzilla, before Godzilla finishes it off with two powerful atomic breaths. The military units then organize in the Aokigahara Forest to reroute Godzilla back to the sea. However, the military's radar shows that a large mass (much bigger than Godzilla himself) moving towards his location, and Godzilla is attacked by Subject 19 (no longer having an atomic breath ability), who survived the attacks from Godzilla, having grown a new, more monstrous head, and is now in its final form (identical to Biollante's final form from the original "Godzilla vs. Biollante" movie), now definitely a female, before Godzilla fights Subject 19 (who's now officially named "Biollante"), before she carries him with her sharp teeth and tusk-filled jaws and throws him right onto a mountain near a village. Godzilla then recovers quickly and shoots out his atomic breath at one of Biollante's vines/tentacles/tendrils and then at her abdomen, before Biollante shoots her corrosive sap (missive, green fireball) from her jaw at Godzilla, but not long before Godzilla shoots out golden rays of beams that causes a massive nuclear-like explosion. The toxic gas released by Biollante seems to have a paralyzing effect on Godzilla, causing him to loose consciousness for 4 days before he returns to the sea. He is then inactive after this film's event for 3 months (but he is still alive). In the end of that film's event, thousands of non-mutant humans died or are seriously injured, and Yokohama has transformed forever. Unlike in the original 1989 film, Biollante survives the final battle and now takes controls over parts of the Aokigahara Forest. Although generally peaceful now (as well as now longer being in constant pain and suffering from her mutated body), her presence has attracted several other superfauna (including El Gusano and Skeetera) that sometimes become aggressive when she's threatened. The consciousnesses of the 15 human victims of Shelter 54 are all still present forever in the form of Biollante. Due to the incident that has led to the accidental creation of Biollante, the use of G-Cells has been banned or made illegal in all experimental research. Additionally, most (if not all) C level shelters have been upgraded appropriately for automatic decontamination protocols and to keep people inside the shelters safe from any possible mutagen leaks/floods, preventing the same mistake that occurred with Subject 19/Biollante from ever happening again. There should also be quotes/subtitles from the (non-mutant) human characters in this movie so we know what the characters are saying.
