MegaKaiju
Fire Kaiju

10
This is no longer a beast β it is a continent-sized god of fire, a cataclysmic force of nature towering into the stratosphere. At 50 kilometers tall, the Fire Kaiju is visible from other countries, and its mere existence bends the sky, stirs storms, and shifts tectonic plates.
Its IQ of 100 makes it as intelligent as a human, capable of tactical thinking, strategic attacks, and even understanding human communication β though it does not care.
This is a living extinction event.
