At home in deep subterranean cave systems and anywhere in the darkness, they are the ‘bump in the night’. They are the creepy crawlies, ever patient and always using the shadows to their advantage. Obscuring their maneuvers and strategy, the Darkness civilization tends to be sneaky and deceptive – choosing the right moment to pop out and scare / attack /greet their enemies. Their great nemesis, of course, is Light, whom they view arrogant and controlling – ever ready to illuminate their secretive ways. Their co-existence with the Nature and Fire civilizations are tenuous and sometimes stormy, though Fire’s passions resonate more with Darkness, and they are amused by Nature’s tribal ways.
Their best ally is Water, whom they can join seamlessly with to fight side by side with. The Darkness Civilization has a certain spooky, creepy side with its undead, demons and especially ‘the masks.’ Many creatures of Darkness always wear masks, which keeps others guessing about who or what is beneath. The ‘unpredictable’ side of darkness (and what may come out of it) is intriguing. On a deeper level, dark things are neither all bad nor all good – and darkness offers many lessons useful not only to dueling but to life.
The Fire Civilization is shimmering deserts and rocky badlands, all surrounded by magma-belching volcanoes. In this blast-furnace land live creatures with explosive personalities and high-explosive weaponry. Fire creatures don’t do a lot of planning, and do less negotiating, making Fire the most warlike civilization.
Fire is driven by the need to act now and think later. Other civilizations see Fire as impulsive, angry, and out of control, but Fire knows that the key to winning is quickly acting on instinct.
The Water Civilization is located in the depths of any sufficiently large body of water, be it a pond, mighty river, lake or ocean. The most centered and naturally peaceful civilization, they often do not start battles, but once roused into a storm, their relentless counter attacks can decimate their foes.
They’re streamlined and highly technological – nearly as much so as the Light Civilization. They exploit microchip technology as well as hydraulics. Because speaking is difficult underwater, many inhabitants use mental telepathy to communicate. And the Water denizens can utilize supersonic/electromagnetic waves.
The Light civilization rises above the other civilizations, literally; they live in majestic, floating cities in the sky that operate with clock-like precision. For Light civilization creatures, intellectual power reigns supreme, and they have harnessed their superior intelligence to create elegant and advanced technologies to help them in all aspects of their lives. In fact, Light creatures' polished metal bodies are mechanical constructs designed to hold their souls, which are made of light. Due to their nature, they are able to use light in all its forms (waves, particles, beams, etc.), whether for defense or offense.
The Nature civilization is the largest kingdom in the Creature realm, and it threatens to grow larger every day. This expansion causes continuing conflict with the other Civilizations, because the nature of Nature is growth in every direction. The civilization’s motto is simple: Survive at all costs. Nature civilization creatures are often tribal, with a tendency toward spiritual and shamanistic practices.
Not surprisingly, the Nature civilization tends to be more primitive than the others, relying more on brute strength and weaponry found in their surroundings (thorns, vines, shells, poisonous stingers, etc.)
the farthest civilization in Kaijudoa is the Zero civilization, Many Visiters go to the Zero civilization and even also there main three races Zenith, Oracle and Outrage and all civilizations shared races with the Zero civilizations during that time before sharing races with Earth and also the Zero civilizations has Light, Water, Darkness, Fire and Nature as their allies and also their artifact is Waraxe of Zero's Twinsanity

stated by Isao in other hand He said the civilization is almost like India kind of realm that form in Ice and even that which makes Jelly questioned that Ice and Water can form in one piece of Snow Ball in their realm and also the artifact for the Glaicer civilization is Wall Shield of Frozenless
also as that Glaicer civilization gave Nature an little of Snow to play on and as that Ice creatures are likely friendly, kind and also loving to the Nature creatures as but even also Glaicer civilizations are more likely caring to the Nature civilization just by giving them Snow to play and make on and so Glaicer was the support civilization in all the Kaiju Realm
