Unlike other Kaiju, Plagueis prefers to remain hidden and only defend itself when discovered. It unleashes and many parasitic creatures that resemble different insects and arachnids. It dwells deep on the ocean floor. The cockroach-like creatures it realeases, are the size of microbes and they cannot be filtered easily thus transferring them into the human body through drinking or washing water. They control the minds of their hosts. The spider-like creatures it releases, spread disease e.g. influenza.
