It was finally defeated by a complex plan orchestrated by government official Rando Yaguchi, but still could not be killed and remained a potential threat as It stood frozen in the ruins of Tokyo.

[6] Anno and Higuchi wanted the kaiju to mutate throughout the film, even as far as demonstrating the creature shed its skin by tearing itself out of its old body,[7] but Toho vetoed the idea.

In this form, a red glow can be visibly seen from its fins, indicating that its mutation consumes much energy and produced a lot of heat.

The shade of skin for this form is a much darker black color with red glowing highlights around and those exposed parts of the body such as his neck, back and legs.

[6] A deleted scene within the film showed the monster's ability could replicate through any matter separated from itself, in the scene where the JSDF investigate areas contaminated with radiation find a biomass, a mass of flesh, that was blown off from Shin Godzilla by the bunker-buster bombs, and this biomass had sprouted eyes and teeth.

Some theories by individuals hint that Goro Maki, the scientist who created Shin, and disappeared in the film, had merged with the creature resulting in the creation of the humanoid forms.

Shin Godzilla is awakened from Tokyo Bay where it roars and starts attacking Japan by passing the Tokyo Sky Tree, Shuto Expressway, Saitama's prefecture border at Yashio's Ukizuka district, destroys the Ukihana bridge with his thick legs, advancing towards Kasukabe.

The Prime Minister thought that the creature couldn't go on land but as soon as the PM tried to calm the public, Shin made landfall in Tokyo's Kamata district stumbling around on his hindlegs, dropping blood from his gills.

[19] Shin Godzilla resurfaced again in his fourth form where it made landfall at Kamakura city, and left a trail of destruction and radiation in his wake.

The JSDF then use all of their weapons, their Type 10 tanks, various choppers, and two Mitsubishi F-2 fighter jets, and not a single scratch was left on Shin's skin.

As Shin Godzilla continued to advance towards Tokyo, the JSDF planned the United States to intervene with a massively destructive airstrike plan, and the Prime Minister is informed from an American ambassador that the USAF already deployed three Northrop B-2 Spirit stealth bombers armed with Massive Ordnance Penetrator bombs going to Japan.

Shin fires his atomic breath toward the city, cutting several skyscrapers in half and destroying the Eurocopter EC225 Super Puma helicopter carrying the Prime Minister.

[19][20] The next day, Shin Godzilla wakes up from the hibernation by Operation Yashiori when in the first phase, it was hit by driverless N700 Series Shinkansen bullet trains armed with C4 explosives.

In the fifth phase, it regained consciousness and destroyed the first crane platoon with his atomic breath from his mouth, but more driverless-trains were sent to crash into Shin.

At the last shot of the film, it is shown that Shin Godzilla was evolving to his 5th form, however the next evolution was halted upon his body getting frozen, as the monster realized the power of humanity.

[20] Following the events of Second Impact in Neon Genesis Evangelion, Shin Godzilla appeared and knocked the GLAUX out of the air.

The vehicle is nearly crushed to death by Shin's foot, but it is saved just in time and picked up by Evangelion Unit-01 and its pilot, Shinji Ikari.

However, Shin Godzilla seems to be unaffected by their attacks, and swats them away with relative ease by shaking his body and swinging his tail at them.

For a brief moment, the creature seems defeated, only for Ghidorah to rise completely unharmed from the rubble and turns his attention to the frozen Shin Godzilla.

Firing its gravity beams at it, Shin's body begins to glow again, seemingly using Ghidorah's attack to regain his energy.

Having defeated the rival, Shin Godzilla walked slowly back into the ocean, leaving Osaka-III and the EVA Units peacefully.
