Introduction:
In the wake of the Osaka Incident, the possibility of monsters existing hidden in a state of suspended animation across the globe became a reality. It was only a matter of time before news of such beings could no longer be kept secret from the public. Forces of such catastrophic power do not bend to the whim of governmental propaganda, and they do not conform to the will of man. The existence of Leviathan and Behemoth brought into question whether other beings of ancient mythologies were derived from actual entities lurking in the shadows. The trinity of Hebrew primordial beasts remained incomplete without he who governs over the heavens above. The beast heralded as ruler of the skies, Ziz, had yet to make its presence known. Monarch would rather this remain as such, lest the skies be literally torn asunder…

Recorded History:
Search efforts for the resting places of Behemoth and Leviathan became a serious priority for Monarch after the Osaka Incident. Traditional means of locating the beasts proved ineffective due to their immunity to both sound and radio wave detection. The USS Nautilus was again brought forth in an attempt to lure out Leviathan from its murky resting place. However, despite search efforts scouring deep sea basins across the globe, no evidence of the creature was unearthed. It was as if it simply disappeared into the abyss. Dr. Serizawa wished to continue the search, but Monarch had more lucrative projects to fund. The search was quickly abandoned. However, seismic analysis of Mesopotamia did offer some insight into where Behemoth may be residing. Readings indicate the juggernaut may be resting somewhere in the Zagros Mountains. However, these findings are still being held under scrutiny and may be found to be statistically insignificant compared to background values. Further analysis is required…

In the December of 1956, Monarch received their first major lead on the potential whereabouts of a new species of MUTO after the Osaka Incident. News came from the small mining village of Kitamatsu, located in the Nagasaki Prefecture of Kyūshū. The lowest levels of the town’s mining shafts had begun to flood. Reports came in soon after two miners, Goro and Yoshizou, descended into the mines to begin their shifts. Both men had been at odds with each other earlier that day, and neither individual returned after the completion of their shift. Concerns were raised about the whereabouts of the two men, so the head of security for the mines—Shigeru Kawamura—led a team to investigate. There he discovered the rising water levels, finding Yoshizou’s gruesomely eviscerated body bobbing in the shallows. Kawamura and his team dragged Yoshizou’s corpse back to town for post mortem.

The doctor’s report was grim. Yoshizou had deep lacerations across his bloated body, with large portions of the corpse having been consumed and badly mangled. The deep cuts resembled wounds from a blade, prompting some to suspect Goro’s involvement in Yoshizou’s death. After all, Goro and Yoshizou had a history of distaste for each other. However, this theory did not account for the partially-digested body, which sparked even more concern. Kawamura insisted the other miners let authorities handle the situation before it escalated.

Authorities did investigate the mines further to attempt and locate the missing Goro and solve the mystery of the crime. Three policemen entered the mine through the only opening, ensuring they would cross paths with Goro if he attempted to escape. None of the men return from the excursion. Fearing the worst, Kawamura headed a search and rescue party into the mines himself accompanied by further law enforcement. They descend into the depths of the mine, venturing into the rising waterway. However, when they finally discover the whereabouts of Goro, the situation only worsened. Like Yoshizou before him, Goro was discovered lifeless in the rising waters at the base of the mine. His body, however, was in an even worse condition, having been consumed to a point where he was barely distinguishable. The sight was sickening; the scent, repulsive. Further investigation revealed the bodies of two of the policemen; their corpses still being consumed by the creatures that killed them. A new species of MUTO, the creatures appeared as if enormous dragonfly nymphs. Drawn to the commotion, the creatures soon turned their attention to the fleeing men with lightning reflexes. In a fit of panic, the men made a dash for the bank as the policeman fired off several volleys into the murky waters. As the men fled, Kawamura’s quick thinking prompted the release of the mine carts from their holdings. Gravity sent the carts careening into the giant insects, crushing them on impact. The bodies of the fallen men could not be retrieved; an immediate evacuation of the mine was in order.

The situation only continued to deteriorate as the creatures ventured beyond the mines and into the city above. Goro’s sister, Kiyo, had her house raided by one of the creatures the night after the attack. Police involvement repelled the creature, which killed two more policemen before retreating back into the hillside and presumably returning into the mines. Fear arose that this new superspecies may be nesting in the mines and that failure to eradicate them may result in an infestation. The size and ferocity of such creatures would cause the town to become inhospitable if such an event were to occur. As such, Kawamura urged that another excursion into the mines was necessary. Kawamura again descended into the mines accompanied by armed forces. The bodies of the creatures crushed by the mine carts appeared to also have been gnawed at, indicative of cannibalism amidst the species. Goro’s body was retrieved, as were the remains of two of the policemen. However, the 3rd policeman remained unaccounted for. The men ventured deeper into the mines in search of the 3rd policeman’s body, as well as any signs of the MUTOs and where their nest may be. As they descended ever-deeper, they found an expanse that remained unflooded. There, they discovered the gruesome remains of the final policeman, who even in death remain affixed to the phone line he dearly hoped would save his life. Alongside the corpse of the man were further MUTOs, which were stirred by the sudden light and commotion. The creatures immediately lunged at the men, but they were unable to reach them before the mines began to stir geologically. The earth below trembled and soon the mines began to collapse. The creatures were crushed by the debris caused by the destruction of the mines. However, during the ensuing panic, Kawamura became separated from his escorts. The policemen urged Kawamura that they would bring help to dig him out.

While attempting to find a weak point in the debris, Kawamura stumbled upon a massive opening in the mine walls. Water poured from the opening into the mine shafts, indicating the source of the flooding was occurring on the other side. Against his better judgement, he investigated the hole, descending deeper into an uncharted portion of the underworld. At the end of the tunnel, Kawamura discovered an enormous underground chasm. Within the enormous pocket, a swamp had manifested, teeming with these new MUTOs. On the far wall of the pocket appeared to be a vast egg case, likely the spawning point for such a hoard. However, despite death appearing imminent, Kawamura soon discovered he was not alone with the giant bugs. Another entity stirred within the great chasm. Gargantuan even by comparison to the dragonflies, this new MUTO was distinctly pterodactyloid in nature. However, it’s body appeared to be encased in fire. It’s wingtips still blistered with the heat of an active volcano. With its hooked beak, the creature laid waste to the MUTO nest, snapping up the giant insects like a bird pecking at worms in the dirt. Ever single individual was consumed, and the eggnest was torn asunder by massive rending claws on the forelimbs. The entire event was so traumatizing, Kawamura was left scarred with severe PTSD and memory loss once he was rescued from the mines. While his memory eventually returned to recount his nightmare to Monarch, Kawamura was never the same.

Dr. Kyoichiro Kashiwagi of Monarch was brought on to investigate the remains of the insectoid creatures killed in the mine shafts. He described the creatures as being a close relative to the Meganeura brongniarti of the Pennsylvanian subperiod of the Carboniferous. While no evidence of a nymph stage exists for M. brongniarti, the specimens recovered were undoubtedly significantly larger. The creature was given its own species designation, Meganeuron giganteus. A thorough investigation of the mines after the retrieval of Kawamura was conducted to ensure the claimed eradication of their nest had been full-proof. Sure enough, no further nymphs were found within the mines, and the water level quickly receded as well. However, no evidence of the giant pterosaur feared by Kawamura was uncovered. Despite this, prominent scorch marks found within the giant chasm indicate that the underground network found may be connected to the nearby volcano, Mt. Aso. Further investigation of the mines is ongoing…

Biology:
Complete specimens of M. giganteus were able to be retrieved from the mines, allowing for a thorough analysis of their anatomy. The specimens collected were approximately 15 ft. (4.57 meters) in length and weighed about 4,000 lbs. Morphologically, the M. giganteus nymphs are surprisingly comparable to their odonata relatives. This is the first instance of a superspecies sharing nearly identical anatomical characteristics with a non-superspecies order of organism. M. giganteus possesses an exoskeleton composed of silicon carbide, similarly to the plated zooids present on the dermal surface of S. atranubelum. The strength of the Moissanite complex allows for incredible resistance to external damage, explaining why even police gunfire was unable to stop the creatures when they attacked Kitamatsu directly. This may also be the reason these giant insectoid superspecies are able to attain such a size, as the chitinous exoskeletons of their smaller kin would require a thickness unsuitable for life to support their weight at a comparable size. Like in arthropods, the exoskeleton is segmented, allowing for flexibility at key joints that would otherwise be impossible given the rigidity of the external plating. The external surface is very coarse, covered in varying sizes of dermal spines. The largest spines occur on the tibia, the dorsal surface of the abdomen, and above the eyes, where they form a prominent ridge. Internal apodemes extensions are comparatively large, likely serving a function similar to the lattice within pneumatized bone, providing structural framework while maintaining a largely hollow internal cavity.

Haemolymph floods the entirety of the hemocoel, bathing all internal tissue. This open circulatory system is common among arthropods and a chief reason why scientists believe they are incapable of reaching gigantism comparable to chordates. How M. giganteus has been able to overcome this obstacle requires further research, but a few theories have been proposed. The species possesses a complex system of external book gills across the lateral surface on either side of their segmented abdomens, protected dorsally by large, plate-like spines. The various appendages of this organ move rhythmically to pump haemolymph in and out of the membranous lamellae where gas exchange occurs. A thin membrane coats the capillaries of the lamellae to allow for osmoregulation between the water and the body fluids. This osmoregulation allows M. giganteus to be euryhaline, actively osmoconforming their internal osmolarity to the surrounding environment. This membrane also traps moisture, allowing M. giganteus to leave the water for several hours at a time while continuously being able to breath. This system provides enough oxygen to the organism to maintain an active lifestyle. It is uncertain how this system is modified for the adult stage of the organism, as no adult specimens have been found. However, shed exoskeletons found amongst the remains of the destroyed nest indicate the species does go through an extensive molting process. Some of the husks left behind are quite large, appearing to be from 12th instar individuals. This has raised concern about adult M. giganteus individuals still being present within the underground cave systems…

M. giganteus possesses three sets of paired appendages on the thorax. However, while the 2nd and 3rd pairs are analogous to odonata limbs with two distinct claws at their tops for grasping, the 1st pair of limbs have been highly modified into chelipeds. The tarsus and metatarsus segments have been developed into chelae that interlock to obtain a vice-like grip on prey. The closing mechanism for these 2 ft. (0.61 meters) long pincers is hydraulically pressurized using internal fluids and stored water in the abdomen, allowing for incredible snapping speeds. The gashes found on the bodies of the men who lost their lives in the mines matched the serrations found on the interior edge of the claws. Analysis of the cave opening where the M. giganteus nest was located have found large gash marks on the walls that fit perfectly with the pincers of the species. Further evidence indicates that M. giganteus may use their claws to burrow through solid bedrock, explaining how they were able to enter the mines. Water samples taken from their bog were found to chemically match the waters of Hanjaku Lake, indicating the swarm may have originated in said body of water and carved their way into the mines. Monarch believes to have found the location of their burrowing tunnel, but whatever occurred to destroy their nest also caved in the entrance…

The mouthparts of M. giganteus are clearly designed for the rending of flesh. The labrum possesses two claw-like protrusions which allow for superior grasping and tearing of prey with rapid forward-and-back movements of the appendage. Similarly, the mandibles both have serrated claw-like extensions that properly pulverize flesh with rapid chewing motions. Wounds sustained by the men slain in the mines match the lacerating capabilities of M. giganteus jaws. Beneath the jaws themselves, the nymphs possess a jointed labium with two large graspers at its tip. This appendage folds back underneath the thorax like an arm at rest. The pseudo-limb is also powered hydraulically, able to fully extend from rest in 23 milliseconds. This incredible extension speed prevents almost any reaction from a prey item once it has blundered into striking range, which is approximately 3 ft. (1.22 meters) when fully extended. The claws at the tip of the labium pierce prey and seize it for retraction. The secure grip allows prey to be drawn back towards the jaws, where it is consumed immediately, often while still alive. The pincers aid in the manipulation of prey, as well as the tearing apart of more sturdy body parts for smoother consumption. Glands present on the underside of the thorax store coal tar, which can be expelled orally. It is uncertain what purpose this ability serves, although it does indicate that naturally-occurring hydrocarbons are consumed as part of the diet. This substance may be used to coat prey to be stored for later, like the silk of a spider. It’s toxic qualities may also be used to subdue prey, although this is unlikely. However, bodies found with this tar attached to them always had it plastered on their face, particularly in the mouth and throat. Further analysis is required.

M. giganteus possesses two large compound eyes on either side of its head. Due to the size of the mouthparts, these do not overlap like they do in non-superspecies odonates. However, a trio of smaller simple eyes present on the dorsal surface of the head between the two compound eyes allows for an exceptionally range of vision. The eyes possess 30 types of opsins, allowing for an incredible range of color vision, including the infrared and ultraviolet spectrums. Two small antennae are present above the mouthparts. Their exact purpose is as-of yet unknown, but they may detect minute pressure changes in the water as a means of detecting nearby prey.

Despite their similarity to odonate arthropods, M. giganteus does not appear to be closely related genetically. In fact, M. giganteus possesses a genome composed of RNA instead of DNA, similarly to S. atranubleum. What’s more, M. giganteus tissue is high in concentrations of batrachotoxin like the Shi no Mure. Why M. giganteus convergently evolved odonate-comparable biology is uncertain, but it may have been a form of mimicry. How this serves the species is unknown, but this discovery has forced Monarch to rethink their concept of Dr. Randa’s superspecies ecosystem hypothesis. The relationship between S. atranubelum and M. giganteus is equally perplexing. Dr. Kashiwagi has theorized that at the dawn of life on Earth, two lineages may have branched off from each other. One transfered over to DNA as their means of genetic information storage—our own lineage—while the other retained RNA for the same function, and this lineage may well be equally as diverse as our own. This theory provides the haunting reality that there may be an enormous number of superspecies akin to M. giganteus still as-of yet unknown to science lurking in the most remote of locations across the globe. Monarch is currently investigating why the M. giganteus swarm arose and where they came from originally…

Within the underground pocket where the M. giganteus swam remains were found, a large network of interconnected cave systems has been found. Traveling deeper into these systems has proven Kawamura’s claims haunting valid. The largest of these tunnel ways leads to the caldera of Mt. Aso. Laying dormant within the liquid magma is another enormous MUTO species. Dr. Kashiwagi has named this new species Rodanus conflatum, although Dr. Serizawa has nicknamed the creature Ziz (זיז) as a completion of the Hebrew trinity of primordial beasts.

It is almost impossible to study Ziz as a specimen, despite the fact that it lies motionless within the caldera. The creature, like with Leviathan and Behemoth, appears to be able to negate all sound and electromagnetic wave frequencies, rendering it untraceable. In addition, its placement within the magma itself makes it incredibly difficult to approach for sample collection. However, specialized high-temperature equipment has allowed for small numbers of samples to be collected from the external surface of Ziz. To monitor the creature, a Monarch containment facility was constructed around Mt. Aso. This facility includes a restraining system, which seals the opening of the volcano to prevent Ziz from escaping should it ever be roused from its slumber. This location is now known as Outpost 56.

Analysis of the samples collected from Ziz indicate that they are in fact not tissue samples, but clumps of volcanic glass. It is postulated that the creature wears a thick coating of hardened volcanic rock upon its hide as an added means of defense. This protective layer is thick enough to present a mosaic throughout, with deeper regions of the rock being more solid than those closer to the surface. Due to the lack of proper tissue samples, it is impossible to determine the true nature of Ziz’s biochemistry. However, based on the similarities it possesses with Leviathan and Behemoth, it is likely they are largely comparable at the base anatomical level.

Ziz possesses wings, which are currently wrapped around the creature in its suspended state of pyrostasis. These wings are formed by a layer of tissue, known as the brachiopatagium, stretched between an elongated 4th digit on the forelimbs and the tail. This structure is comparable to the wings of the pterosauria flying reptiles of the Mesozoic. However, unlike the wings of pterosaurs, the metacarpals of Ziz are not significantly elongated, resulting in a hand positioned relatively close to the axis of rotation of the wrist. This would allow for more manipulation of the hand for a variety of different uses besides simply terrestrial locomotion. The propatagium of the wing is also significantly reduced, with the seeming absence of a pteroid bone. The wings themselves appear to serve a purpose in thermoregulation. The large surface area of the wing’s membrane is likely filled with a high concentration of blood vessels. These may serve to transfer internal body heat from the center of mass to the extremities for dissipation. This would cause the wing membranes, especially the trailing edge, to be exceptionally hot compared to the rest of the organism. It has been suggested that, outside the confines of the molten lake Ziz currently rests within, this heat alone would be enough to liquefy the plastered volcanic glass upon the mebrane’s surface. This would cause the tips of the wings to constantly be in flames. This attribute, if proven valid, would be a devastating asset in combat.

The feet of Ziz are digitigrade, more like those of modern accipiters than those of pterosaurs. The 1st digit is located posteriorly and rotated inwards towards the center of the body. This digit may be flexible enough to rotate completely backwards to improve grip on a target, providing a functionally anisodactyl toe configuration. The other three digits are anterior and possess larger claws than the 1st digit, with the largest being on digit 3. The musculature of the hindlimbs likely offer these digits incredible grip strength, making Ziz’s talons exceptionally deadly. Two large spurs protrude from the back of the tarsometatarsus, with the 1st spur being half the size of the 2nd. The purpose of these spurs is unknown.

Ziz possesses an impressive skull. The jaws are covered in beak tissue, likely composed of a similar material to the beak of Behemoth. The tip of the upper beak is curved downwards, with the edges possessing prominent serrations. These serrations likely serve the same function as teeth, as Ziz is prominently toothless. The most striking feature of the organism are impressive cranial crests jutting from the back of the skull. Two large skull protrusions extend backwards from a ridge above the eyes. These curve inwards slightly as they taper to a point. The purpose of these structures is entirely unknown. It has been suggested that they may be hollow, perhaps even support a system of air-filled tubes that could serve in communication. They may also be for display purposes. Ziz’s eyes are comparatively large, with the structure of the skull, allowing for a strong overlap of vision. This likely provides Ziz with incredible binocular vision, an essential component to any predator that hunts from above. Ziz’s biology is clearly indicative of an organism built for flight. However, it still remains unknown how such an organism could produce enough lift to make it off the ground. The discovery that Leviathan and Behemoth are capable of producing strong electromagnetic fields around them has added additional evidence to this being the key to flying MUTO’s ability to resist gravity. However, while Ziz remains dormant within Mt. Aso, it will be impossible to conduct a thorough analysis of the organism’s biology. Research on Ziz continues to this day, although Monarch insists that direct interference with the specimen be kept to a minimum, lest it be awakened from pyrostasis…

Behavior:
The individuals observed of M. giganteus were incredibly aggressive. While social organisms, pack hunting strategies were not utilized. The species appears to be solitary-but-social, with individuals sharing living spaces but not directly caring for one another. Hunting is a solitary matter, and once prey has been seized, squabbles often break out over the resources. The species is also not above cannibalism, with deceased members being seen as nothing more than another meal. M. giganteus are likely a r-selected species, with egg clumps laid by a single adult capable of producing several hundred nymphs. While the nymphs present in the mines appeared to remain close to their spawning location, they did not display any defensive behavior for the nest itself. It is entirely possible that adult M. giganteus, however, are more protective of their brood and possess an entirely different behavioral spectrum.

Nothing is known of Ziz’s behavioral patterns, as the creature remains dormant within the caldera of Mt. Aso. Kawamura’s reports indicate the creature may prey upon M. giganteus, although such reports cannot be confirmed. If this claim proved true, it would provide additional evidence to Dr. Randa’s theory of a superspecies ecosystem.

This membrane also traps moisture, allowing M. giganteus to leave the water for several hours at a time while continuously being able to breath. This system provides enough oxygen to the organism to maintain an active lifestyle. It is uncertain how this system is modified for the adult stage of the organism, as no adult specimens have been found. However, shed exoskeletons found amongst the remains of the destroyed nest indicate the species does go through an extensive molting process. Some of the husks left behind are quite large, appearing to be from 12th instar individuals. This has raised concern about adult M. giganteus individuals still being present within the underground cave systems…

M. giganteus possesses three sets of paired appendages on the thorax. However, while the 2nd and 3rd pairs are analogous to odonata limbs with two distinct claws at their tops for grasping, the 1st pair of limbs have been highly modified into chelipeds. The tarsus and metatarsus segments have been developed into chelae that interlock to obtain a vice-like grip on prey. The closing mechanism for these 2 ft. (0.61 meters) long pincers is hydraulically pressurized using internal fluids and stored water in the abdomen, allowing for incredible snapping speeds. The gashes found on the bodies of the men who lost their lives in the mines matched the serrations found on the interior edge of the claws. Analysis of the cave opening where the M. giganteus nest was located have found large gash marks on the walls that fit perfectly with the pincers of the species. Further evidence indicates that M. giganteus may use their claws to burrow through solid bedrock, explaining how they were able to enter the mines. Water samples taken from their bog were found to chemically match the waters of Hanjaku Lake, indicating the swarm may have originated in said body of water and carved their way into the mines. Monarch believes to have found the location of their burrowing tunnel, but whatever occurred to destroy their nest also caved in the entrance…

The mouthparts of M. giganteus are clearly designed for the rending of flesh. The labrum possesses two claw-like protrusions which allow for superior grasping and tearing of prey with rapid forward-and-back movements of the appendage. Similarly, the mandibles both have serrated claw-like extensions that properly pulverize flesh with rapid chewing motions. Wounds sustained by the men slain in the mines match the lacerating capabilities of M. giganteus jaws. Beneath the jaws themselves, the nymphs possess a jointed labium with two large graspers at its tip. This appendage folds back underneath the thorax like an arm at rest. The pseudo-limb is also powered hydraulically, able to fully extend from rest in 23 milliseconds. This incredible extension speed prevents almost any reaction from a prey item once it has blundered into striking range, which is approximately 3 ft. (1.22 meters) when fully extended. The claws at the tip of the labium pierce prey and seize it for retraction. The secure grip allows prey to be drawn back towards the jaws, where it is consumed immediately, often while still alive. The pincers aid in the manipulation of prey, as well as the tearing apart of more sturdy body parts for smoother consumption. Glands present on the underside of the thorax store coal tar, which can be expelled orally. It is uncertain what purpose this ability serves, although it does indicate that naturally-occurring hydrocarbons are consumed as part of the diet. This substance may be used to coat prey to be stored for later, like the silk of a spider. It’s toxic qualities may also be used to subdue prey, although this is unlikely. However, bodies found with this tar attached to them always had it plastered on their face, particularly in the mouth and throat. Further analysis is required.

M. giganteus possesses two large compound eyes on either side of its head. Due to the size of the mouthparts, these do not overlap like they do in non-superspecies odonates. However, a trio of smaller simple eyes present on the dorsal surface of the head between the two compound eyes allows for an exceptionally range of vision. The eyes possess 30 types of opsins, allowing for an incredible range of color vision, including the infrared and ultraviolet spectrums. Two small antennae are present above the mouthparts. Their exact purpose is as-of yet unknown, but they may detect minute pressure changes in the water as a means of detecting nearby prey.

Despite their similarity to odonate arthropods, M. giganteus does not appear to be closely related genetically. In fact, M. giganteus possesses a genome composed of RNA instead of DNA, similarly to S. atranubleum. What’s more, M. giganteus tissue is high in concentrations of batrachotoxin like the Shi no Mure. Why M. giganteus convergently evolved odonate-comparable biology is uncertain, but it may have been a form of mimicry. How this serves the species is unknown, but this discovery has forced Monarch to rethink their concept of Dr. Randa’s superspecies ecosystem hypothesis. The relationship between S. atranubelum and M. giganteus is equally perplexing. Dr. Kashiwagi has theorized that at the dawn of life on Earth, two lineages may have branched off from each other. One transfered over to DNA as their means of genetic information storage—our own lineage—while the other retained RNA for the same function, and this lineage may well be equally as diverse as our own. This theory provides the haunting reality that there may be an enormous number of superspecies akin to M. giganteus still as-of yet unknown to science lurking in the most remote of locations across the globe. Monarch is currently investigating why the M. giganteus swarm arose and where they came from originally…

Within the underground pocket where the M. giganteus swam remains were found, a large network of interconnected cave systems has been found. Traveling deeper into these systems has proven Kawamura’s claims haunting valid. The largest of these tunnel ways leads to the caldera of Mt. Aso. Laying dormant within the liquid magma is another enormous MUTO species. Dr. Kashiwagi has named this new species Rodanus conflatum, although Dr. Serizawa has nicknamed the creature Ziz (זיז) as a completion of the Hebrew trinity of primordial beasts.

It is almost impossible to study Ziz as a specimen, despite the fact that it lies motionless within the caldera. The creature, like with Leviathan and Behemoth, appears to be able to negate all sound and electromagnetic wave frequencies, rendering it untraceable. In addition, its placement within the magma itself makes it incredibly difficult to approach for sample collection. However, specialized high-temperature equipment has allowed for small numbers of samples to be collected from the external surface of Ziz. To monitor the creature, a Monarch containment facility was constructed around Mt. Aso. This facility includes a restraining system, which seals the opening of the volcano to prevent Ziz from escaping should it ever be roused from its slumber. This location is now known as Outpost 56.

Analysis of the samples collected from Ziz indicate that they are in fact not tissue samples, but clumps of volcanic glass. It is postulated that the creature wears a thick coating of hardened volcanic rock upon its hide as an added means of defense. This protective layer is thick enough to present a mosaic throughout, with deeper regions of the rock being more solid than those closer to the surface. Due to the lack of proper tissue samples, it is impossible to determine the true nature of Ziz’s biochemistry. However, based on the similarities it possesses with Leviathan and Behemoth, it is likely they are largely comparable at the base anatomical level.

Ziz possesses wings, which are currently wrapped around the creature in its suspended state of pyrostasis. These wings are formed by a layer of tissue, known as the brachiopatagium, stretched between an elongated 4th digit on the forelimbs and the tail. This structure is comparable to the wings of the pterosauria flying reptiles of the Mesozoic. However, unlike the wings of pterosaurs, the metacarpals of Ziz are not significantly elongated, resulting in a hand positioned relatively close to the axis of rotation of the wrist. This would allow for more manipulation of the hand for a variety of different uses besides simply terrestrial locomotion. The propatagium of the wing is also significantly reduced, with the seeming absence of a pteroid bone. The wings themselves appear to serve a purpose in thermoregulation. The large surface area of the wing’s membrane is likely filled with a high concentration of blood vessels. These may serve to transfer internal body heat from the center of mass to the extremities for dissipation. This would cause the wing membranes, especially the trailing edge, to be exceptionally hot compared to the rest of the organism. It has been suggested that, outside the confines of the molten lake Ziz currently rests within, this heat alone would be enough to liquefy the plastered volcanic glass upon the mebrane’s surface. This would cause the tips of the wings to constantly be in flames. This attribute, if proven valid, would be a devastating asset in combat.

The feet of Ziz are digitigrade, more like those of modern accipiters than those of pterosaurs. The 1st digit is located posteriorly and rotated inwards towards the center of the body. This digit may be flexible enough to rotate completely backwards to improve grip on a target, providing a functionally anisodactyl toe configuration. The other three digits are anterior and possess larger claws than the 1st digit, with the largest being on digit 3. The musculature of the hindlimbs likely offer these digits incredible grip strength, making Ziz’s talons exceptionally deadly. Two large spurs protrude from the back of the tarsometatarsus, with the 1st spur being half the size of the 2nd. The purpose of these spurs is unknown.

Ziz possesses an impressive skull. The jaws are covered in beak tissue, likely composed of a similar material to the beak of Behemoth. The tip of the upper beak is curved downwards, with the edges possessing prominent serrations. These serrations likely serve the same function as teeth, as Ziz is prominently toothless. The most striking feature of the organism are impressive cranial crests jutting from the back of the skull. Two large skull protrusions extend backwards from a ridge above the eyes. These curve inwards slightly as they taper to a point. The purpose of these structures is entirely unknown. It has been suggested that they may be hollow, perhaps even support a system of air-filled tubes that could serve in communication. They may also be for display purposes. Ziz’s eyes are comparatively large, with the structure of the skull, allowing for a strong overlap of vision. This likely provides Ziz with incredible binocular vision, an essential component to any predator that hunts from above. Ziz’s biology is clearly indicative of an organism built for flight. However, it still remains unknown how such an organism could produce enough lift to make it off the ground. The discovery that Leviathan and Behemoth are capable of producing strong electromagnetic fields around them has added additional evidence to this being the key to flying MUTO’s ability to resist gravity. However, while Ziz remains dormant within Mt. Aso, it will be impossible to conduct a thorough analysis of the organism’s biology. Research on Ziz continues to this day, although Monarch insists that direct interference with the specimen be kept to a minimum, lest it be awakened from pyrostasis…

Behavior:
The individuals observed of M. giganteus were incredibly aggressive. While social organisms, pack hunting strategies were not utilized. The species appears to be solitary-but-social, with individuals sharing living spaces but not directly caring for one another. Hunting is a solitary matter, and once prey has been seized, squabbles often break out over the resources. The species is also not above cannibalism, with deceased members being seen as nothing more than another meal. M. giganteus are likely a r-selected species, with egg clumps laid by a single adult capable of producing several hundred nymphs. While the nymphs present in the mines appeared to remain close to their spawning location, they did not display any defensive behavior for the nest itself. It is entirely possible that adult M. giganteus, however, are more protective of their brood and possess an entirely different behavioral spectrum.

Nothing is known of Ziz’s behavioral patterns, as the creature remains dormant within the caldera of Mt. Aso. Kawamura’s reports indicate the creature may prey upon M. giganteus, although such reports cannot be confirmed. If this claim proved true, it would provide additional evidence to Dr. Randa’s theory of a superspecies ecosystem.
