500 years after sending cockroaches to Mars to help terraform the planet for human colonization, the first manned mission encounters these evolved, giant, humanoid cockroaches, known as Terraformars, who have developed immense strength and a hatred for humans. A second, elite team of human warriors is then dispatched to Mars to exterminate these formidable creatures and reclaim the planet for humanity.

The Setup:

Terraforming Project: In the 21st century, scientists send cockroaches and moss to Mars to make the planet habitable, with the cockroaches helping to spread the moss and die to provide a food source.

First Mission: A manned mission is sent to Mars a few centuries later, but the crew is quickly wiped out by the mutated cockroaches, transmitting a warning back to Earth.

====================================

The Conflict:

Humanity's Response: A new mission is launched with a squad of genetically modified humans.

The "Terraformars": The cockroaches have evolved into powerful, anthropomorphic beings with incredible strength, endurance, and agility, making them a terrifying and formidable enemy for the human crew.

Mission Objective: The human crew must fight and eliminate the evolved cockroaches to secure Mars for human colonization.

====================================

Terraformars (テラフォーマー, Terafōmā?) are evolved humanoid cockroaches who live on Mars. They possess physical traits and skills that greatly surpass those of normal humans while also possessing at least near-human intelligece. All Terraformars exhibit a natural hatred for humans; much like how humans instinctively hate cockroaches which has led to conflict between the Terraformars and humanity.

Appearance:

The Terraformars are human-sized Martian cockroaches with humanoid bodies. They bear a physical resemblance to Homo erectus.

====================================

Personality:

They are animalistic, adaptable, and bent on survival. They are descendants of cockroaches and seem to bear a sort of instinctive hatred for humanity. . There are many types, and their exact behavior can vary depending on the individual, but they usually keep an emotionless expression on their faces. They don't appear to have much of a society, but the Evolved Terraformars do display a degree of leadership, rallying their brothers into a capable fighting force. Under an Invoker's influence they have sense of community but to them there's is no difference in attachment to their parents than a roadside flower. They also appear to be somewhat intelligent. All Terraformars also have a great work ethic, and since they can't feel pain or exhaustion they're quite liable to literally work themselves to death. These things only serve to help a project an Evolved Terraformar wishes to accomplish.

They prioritize their targets when attacking humans. The first pick is anyone who's holding something (weapons). The second are those who are alone. The third is anyone who's injured and the fourth are female targets.

====================================

History:

Little more than 500 years ago, cockroaches together with some moss were sent on Mars, in order to start a Mars Terraforming Project. 500 years later, when the humans revisited Mars, they saw how much the cockroaches have evolved and now have a human like appearance. Due to their massive strength and numbers, they quickly eliminated all of the BUGS1 crew. Due to an endless downpour of space radiation and -80C temperatures, this harsh environment has finally forced the cockroaches, who have not changed their shape in 300 million years to evolve.

Using the BUGS1 spacecraft, a group of Terraformars managed to land on Earth and create a beachhead, unbeknownst to the governments of Earth who believed to have destroyed the craft in orbit. Later when another group of Terraformars arrived on Earth in the Pacific the Nippon-America Alliance attempted to wipe them out using nukes, however before the payload could be launched from a ship at sea, Terraformar infiltrators from the first wave of Terraformars hijacked a civilian plane, crashing it into the ship. Later the Terraformars went underground, after the survivors from the Annex returned, the Terraformars had been responsible for kidnappings all across Japan.

It seems that they have formed an alliance with China and the Newton Clan, in gathering human specimens for breeding and human testing purposes, and as of now, there are unexplained experiments yet to be revealed by them.

Leadership:

When first seen the Terraformars didn't seem to have a leader or a social structure. All of them had an identical appearance and behavior.

That changed after the appearance of the first 2 Evolved Terraformar at the end of the BUGS2 mission. The first evolved Terraformar, also known as "the invoker" in future chapters, was seen as the Terraformars leader the moment he was born, obeying him from when they first meet him and follow his orders to the letter. They have been seen to bend to their knees in his presence as a sign of obedience.

The second evolved Terraformar was made a general and commanded to kill the annex 1 crew, but he dies due to the hidden bomb on Adolf after he was killed.

With the guidance of the evolved Terraformar, the Terraformars developed a structure and a social order and eventually started evolving themselves.

The Evolved Terraformars are on the top of the social structure followed by the Bugs Surgery Terraformars then followed by normal Terraformars. Under the guidance of their leader, the Terraformars are seen learning, organizing, deconstructing and reconstructing pyramids, farming moths for food, silk harvesting, organizing big scale attacks and ambushes, taking apart satellites and using weapons to help in the creation of the Bugs Surgery Terraformars.

It should be noted that after the death of the second evolved Terraformar in Mars 20 years later, it took the unorganized Terraformars only a week to reorganize and continue upgrading their social structure. After his death, the Bugs Surgery Terraformars raised young normal Terraformars and taught them how to do the Bugs Surgery by observation and repeat alone, succeeding this way to create more that one Bugs Surgery Terraformars from a stolen corpse. They solved the problem of their leader dying by raising more than one. That alone shows how initiative and mentally evolved the Terraformars became over time.

Later, one of those young Terraformars can be seen fully grown leading a group of Terraformars as their leader.

He has his forehead painted with the same marks that the Evolved Terraformars have from birth, and he wears necklaces of various stones, instead of wearing the characteristic silk clothes that the Evolved and Bugs Surgery Terraformars wear.

====================================

Powers and Abilities

Having retained the abilities of the cockroaches they evolved from, they possess heightened agility, strength, toughness, and a sturdy carapace, making them incredibly difficult to kill. They have adapted to high temperature and fire, and also possess humanlike intelligence, learning how to use advanced weapons left by BUGS1 crew. Terraformar's are stated to be able to move up 320 km/h in a single leap and have strength comparable, albeit slightly lower, than a Leaf Cutter Ant (which can lift 50 times body weight).

When they are killed, they lay eggs containing all of their genetic information, effectively attempting to clone themselves. Just like cockroaches, they can survive without their heads or their necks broken and still fight well like that for a substantial time.

But their greatest strength is that they are united and undivided, driven by their hatred for mankind which makes them a truly deadly and powerful force to be reckoned with. Unlike the humans who are divided by discrimination and political desires for power and land, the Terraformars are unified for the common purpose of surpassing and destroying mankind as a whole.

Their power and abilities have been increased a hundredfold, due to them having access to the tools of mankind's weapons and technology, their knowledge on how to perform the surgery giving them the abilities of the insect and animal kingdom at their disposal, access to the mankind's Internet and learning multiple fighting styles from the opponents they fought and killed, long range communication, master infiltration and expert disguising, all which the Evolved Terraformar known as Invoker put to very good use against their hated enemy, Man.

Types

• Evolved Terraformar

Evolved Terraformars were born in BUGS2 from eggs. They were immune to Victoria's sting ability and she couldn't control them. They were also even more similar to humans in appearance, and were much more agile than a normal Terraformar. They also seemed more intelligent and even showed leadership ability, having given order to a Terraformar to not move while BUGS2 escaped pod was leaving.

Evolved terraformars fight using martial arts, and they are intelligent enough to perform Bugs surgery to other Terraformars using severed limbs or other body parts of slain humans who have undergone Bugs surgery. Moreover, one evolved Terraformar, dubbed as "the Invoker", was able to attach Shoukichi's hornet stinger arm after losing his in a plane explosion.

when an evolved Terraformar hatches from an egg, it is usually immune to the cause of its predecessor’s death, further evidence of their genetic memory and rapid evolution.

They have scar like patterns on their foreheads resembling dots and lines. They wear silk robes and the normal terraformars follow them blindly from the moment they see them.

There have been 4 different types of evolved Terraformars seen throughout the series.

Bugs Surgery (バグズ手術, Baguzu Shujutsu) is a special surgery done in order to allow people to spend extended amounts of time in the Martian environment. The survival rate of the surgery is mere 30% and because of the high death chance, most people who are undergoing it have nothing to lose or are in need of money. Through the surgery, an insect DNA array is being inserted into the cells of the human body and with this the cells inside mankind's weak flesh and blood will be able to transform into those of an insect. It will also have better physical endurance, speed and strength, along with some unique insect abilities. The official name is Bug Terraformars Immunotolerance Organ Transplant Surgery.

Taking injection

Bug Transformation

Undergoing transformation

Failing the balance

In order to activate their full insect special abilities, they need an injection with insect tissues. The Bugs Surgery blocks the human body from rejecting insect tissue which wouldn't normally be able to co-exist. It is also possible to go further beyond the balance by injecting even more to get closer to an insect body. However should the effect of the injection last for too long, the candidate would die due to the shock caused by the human immune system. And if there is severe damage to vital organs responsible for dismantling the injection inside the body like the liver or kidneys, will result in a more insect-like transformation and death.

Though called the Bugs Surgery, it is possible to use other animal tissue for the process. For example, one candidate was given cells from an electric eel.

The medication that activates the change can come in a variety of forms, from the normal injection, powder (snorted like cocaine), pills, or even a form of gum. Each version of the medicine is created with the intention of swiftly activating the physical changes to allow the user quick access to their powers. Unfortunately the medication only lasts for about an hour depending on circumstances. The medication is also very tiring for the user as once the drug has run its course it leaves their body completely drained of energy. A second dose of medication will energize the user for another hour but after that runs its course the person drops into a eight hour sleep no matter what.

Weapons:

Terra Formars weapons are typically special "Anti-Terraformar" equipment issued to high-ranking Annex I crew members, but the primary method of combat is through DNA surgery, which grants them powers of insects and animals. The weapons include swords, blades, a multi-sectioned staff, armor, a sonic ninja blade, and other unique items like a throwing shuriken and a compressed regenerative bud. The evolved Terraformars, being strong and fast, are also able to use advanced weaponry, such as firearms and specialized clubs, further complicating the fight for the human crew.

The main weapons in Terra Formars are genetically engineered, anti-Terraformer weapons developed by the M.A.R.S. Ranking and JAPAN Ranking crew, such as Akari Hizamaru's "Hizamaru" sonic blade and Joseph Gustav Newton's "George Smiles" anti-Terraformer coated longsword. In addition to these specialized human weapons, Terraformars themselves have abilities that function as weapons, such as the Archer Fish Terraformar's ability to shoot a high-pressure jet of water.

Human Weapons:

The weapons used by the human Annex I crew are often integrated with their biological M.O. (Modification Operation) abilities.

• Hizamaru (Sonic Ninja Blade): Used by Akari Hizamaru, this blade generates high-frequency sonic waves to fight Terraformers.

• George Smiles (Anti-Terraformer Coated Longsword): The primary weapon of the #1 ranked M.A.R.S. member, Joseph Gustav Newton.

• Kavkaz Svet (Nutritional Compressed Regenerative Bud): Used by Sylvester Asimov to provide a regenerative bud that can be applied to both anti-personnel and anti-Terraformer uses.

• Castor (Anti-Terraformer Odachi): A large, durable sword wielded by the female Japanese member, Samurai Sword.

• Archnebuster Mk.II: A three-sectioned staff used by Marcos E. Garcia.

• Michael's Hammer (Simple Explosive Accelerator Device): Used by Michelle K. Davis.

Terraformer Abilities as Weapons:

Terraformars also possess abilities that act as weapons.

• Archer Fish Terraformar: Can shoot a high-pressure jet of water from its hand with enough force to pierce human flesh.

• Bombadier Beetle Terraformar: Can combine chemicals from its palms to create and expel a massive, hot explosion.

• Jet (Yellow Prawn-Goby): A full-body sonar that allows for 360-degree detection of enemies.

M.O. Operation:

The Mosaic Organ Operation, commonly abbreviated as the M.O. Operation, is a surgery to forcefully re-engineer the human body to survive in the Martian Atmosphere. It has a survival rate of roughly 67%. Women appear to be more compatible with the surgery than men, though it's never specified why. If the surgery is a success, the individual has obtained a Mosaic Organ with the DNA of a compatible organism. Taking a type of drug will bring out the abilities gained through the Mosaic Organ to make the individual capable of facing against the Terraformar race on Mars. The drug's form varies from an injection, a drinkable liquid, a tablet, various smoking devices, a powder, a patch, or even as chewing gum. The crustacean drug has to be smoked as an injection would be difficult with bullet proof skin and because a crustacean's respiratory system holds onto substances (such as water) quite well.

Type Red Operation:

The Type Red Operation was a surgery done to all Chinese members that had the MO Operation to give them the ability to use whatever base organism they had while un-transformed.

Inherited Mosaic Organs:

If a baby from an individual post-surgery of either the Bugs Procedure or the M.O. Operation there is a chance the offspring will have been born with a Mosaic Organ. The offspring will have a 100% success rate in the MO Operation, and will carry over the DNA of the parent. Two examples of successfully inherited Mosaic Organs are Michelle K. Davis and Akari Hizamaru. An example of a child not inheriting the Mosaic Organ would be Adolf Reinhard's child, though it should be noted the child wasn't actually his.
