Godzilla : plague (discord Godzilla redesign contest)

I want to keep this theme of disease as a force of nature. An 'organic sinewy tumor' out of a petri dish look on all phases of the tumor-zilla, basically its second phase manages to bite a chunk out of classic godzilla and rearranges itself in their image, a distorted fleshy one

Started off as a government attempt to come up with a pathogen that can infect and kill kaijus, as trying to kill them with brute force has failed many times before. but it goes awry, soon incidents crop up nationwide following the second phase of tumor-zilla as its small size allows it to hide around the tunnels and sewers of the cities. Yellow toxic gasses starts enveloping metro stations, sending crowds of commuters barelling out of the tunnels, many will later die of the sickness.
in the end following its defeat, mankind once more is left to ponder their mistake of thinking they can control and manipulate even the most microscopic of nature's forces.
