Kaiju (Pacific Rim)

Kaiju is the designation given to a group of titanic-sized, silicon based organisms used by extradimensional beings called the Precursors to begin colonization of a planet.

Little is known about Kaiju anatomy, other than that they have skeletons like Earth's vertebrates, have two brains, and that their body fluids are ammonia-based, extremely acidic, have a vivid blue coloration and are highly toxic to Earth's environment. The appearance of a Kaiju varies wildly between individuals, and although it's clear that they are genetically engineered by the Precursors, it isn't known whether each Kaiju represents a unique individual or one of a variety of species, subspecies or phenotypical variants. At least one Kaiju (Otachi) is able to reproduce on its own. It isn't known if all of them share this ability.

The intellectual capacity of an individual Kaiju is hard to tell, but it is known that they possess a hive mind of sorts, are able to devise battle strategies and concentrate their attacks on urban areas. Their bodies serve as environment for a crustaceanoid parasitic creature known as the Kaiju Skinmite, which needs high quantities of ammonia to live.
