Kreostas

Kreostas is a large Brute Wyvern which has been found inhabiting arid regions.

Physiology
Kreostas is a large Brute Wyvern which has a large rounded head which flattens out more towards the front. This head and part of its neck is covered in thick, bony armor-plating and instead of teeth, it possesses sharp bony plates that function as teeth. However, behind these bony plates, Kreostas possesses large tusks which are separated from the bony plates by gums. The rest of its body is covered in rigid scales instead of the bony plating that covers its head. Its arms are somewhat long and it possess four claws, the second digit being longer than the other three, giving it a kind of paddle-like shape.

Kreostas' head is colored and patterned like the head of a Gila monster, being a light orange and black in color. This coloring slowly transitions into both a lighter and darker shade of sandy brown on its body while still having the same patterning as the head. Its eyes are a salmon pink in color.

Behavior
Kreostas are known to be quite territorial Brute Wyverns, becoming aggressive towards things that threaten its territory, but it seems to ignore monsters it doesn't perceive as a threat to its territory, as long as these don't threaten the Brute Wyvern afterwards. Kreostas have been found to commonly prey on Nibelsnarf, suggesting the idea that the Leviathan is its favorite prey.

Position in Food Chain
Kreostas occupy a position at the top of the food chain, being the apex of the Glassy Sands. They're easily capable of preying upon small monsters thanks to their size and strength, especially their deadly bite force. Larger monsters can also fall prey to the Brute Wyvern as they can be taken down rather well too, as shown with Kreostas commonly preying on Nibelsnarf. Kreostas do have to compete with several equally strong monsters and have to worry about predation from powerful monsters.

Behavior towards Other Monsters
Kreostas is territorial, but not inherently aggressive and will as a result ignore small monsters unless they threaten the Brute Wyvern. Larger monsters will also be ignored if they're on the weaker side, but are more likely to get attacked if they threaten or provoke the Kreostas. Kreostas will immediately be aggressive to monsters which are of similar strength and will run away from powerful monsters and Elder Dragons if it has taken enough damage from them.

Tracks
Kreostas can leave behind a variety of tracks for hunters to utilize in tracking it down. These tracks include "Large Clawed Prints", which can be found on the ground, "Large Irregular Claw Marks", which can be found on the ground or on walls, "Thick Bony Plate Fragments", which can be found on the ground, and "Rigid Scale Fragments", which can be found on the ground.

Hunt Cutscene

 * Location: Glassy Sands
 * Synopsis: As the hunter enters Area 4 of the Glassy Sands they don't initially notice anything out of the ordinary so they start to make their way towards the next area. However, they then suddenly notice what they at first think is a sandstorm coming right towards them. The hunter gets caught in it and they try to cover themselves from it, hoping it passes by quickly. They then notice however that it seems to be clear towards their sides, making them reconsider it being a sandstorm. So, the hunter quickly leaps out of the supposed sandstorm and realizes it's in fact some kind of tunnel of sand shot at them. It then suddenly stops and the hunter looks towards it came from which is when they notice something large moving towards them, it blanketed by the shadow from a passing by cloud. As the figure moves towards the hunter, the camera zooms out to more of a bird's eye view, showing both the hunter and the creature. The cloud passes by and the light from the sun falls on the monster, revealing its full appearance and the hunter realizes it has to be the Kreostas they've been tasked with hunting. The Kreostas growls and then roars at the hunter, marking the start of the hunt.

Ecology Cutscene

 * Location: Dunes
 * Synopsis: The cutscene begins by showing a bunch of Rhenoplos challenging one another as they're growling at another and pawing the ground. The two Rhenoplos then charge at one another and ram each other, colliding with their crests while pushing against each other. Suddenly, sand a small distance to their side starts kicking up as something is moving through it and it quickly makes its way towards the two Rhenoplos. As the two take a step back and are about to ram into one another again, a Nibelsnarf bursts out of the ground from the sand and chomps up the two Scelidians. The camera then shows a small patch of sand somewhere else as a foot from a monster steps on it, before moving again. As the Nibelsnarf is finishing up its meal, it seems to be alerted by something nearing it. Suddenly, a Kreostas charges at high speeds towards the Nibelsnarf and manages to bite the side of its head. The Nibelsnarf struggles against the Brute Wyvern which is starting to drag it around. The Nibelsnarf manages to escape the grasp from the Kreostas' jaws momentarily, now having a chunk missing out of the side of its head, but the Brute Wyvern then manages to get itself under the Leviathan and uses its brute strength to flip it on its back. The camera zooms back some more as the Leviathan tries to get back onto its feet, but the Kreostas puts one of its feet down on it and bites the soft underside, killing the Nibelsnarf as it slowly stops struggling. The screen slowly starts to turn to black as the Kreostas begins eating from the Leviathan, ending the cutscene.

Abilities
Kreostas are large Brute Wyverns which means they possess a large degree of physical strength which they showcase with their brutish moves. The armor-plating on their head protects them well from attacks and their rigid scales can seemingly just as easily withstand attacks from threats. Its special jaws are connected to powerful jaw muscles which are capable of both quickly opening and closing these jaws, basically functioning as giant scissors. By opening these jaws quickly, Kreostas is capable of sucking in large amounts of sand which it can then spew back out towards threats. It's also capable of using its jaws to rip rocks out which it can then toss towards foes or crush with its jaws, similarly to Tetsucabra.

Rage and Tired States

 * Rage State: When Kreostas becomes enraged, it'll have raspy breath and the grooves in between the armor plating will give off a slight orange glow.
 * Tired State: When Kreostas becomes tired, it'll start drooling and it'll fall over after doing some of its attacks alongside sometimes failing to do its elemental attacks.

Frenzy, Apex, Hyper and Tempered
Kreostas can be affected by the Frenzy Virus and thus be turned Frenzied, but they've even been known to be capable of overcoming the Frenzy Virus and attaining the Apex State. Kreostas have also been found in the Hyper and Tempered States.

Frenzied Kreostas have the usual changes of a Frenzied monster, but are also capable of causing Frenzy Virus pools with their sand breath.

Tempered Kreostas are considered Threat Lv2 Tempered Monsters and have the usual changes of a Tempered monster.

Hyper Kreostas have the usual changes of a Hyper monster.

Apex Kreostas have the usual changes of an Apex monster.

Mounts
Kreostas has a mount animation like that of Barroth or Brachydios and can be mounted in three places: its head, body and tail.

Whenever Kreostas is mounted on its head, the hunter will either be located on top of the Kreostas' head or hanging from either side of its head. The Kreostas will try to get hunters off by violently shaking its head around, by running around and jumping around, by slamming the side of its head into walls and by slamming its head into the ground.

Whenever Kreostas is mounted on its body, the hunter will either be located on the back of the Kreostas or hanging from either side of its body. The Kreostas will try to get hunters off by shaking its body, by running and jumping around and by slamming the side of its body into walls.

Whenever Kreostas is mounted on its tail, the hunter will either be located on top of the tail, in front of behind the fin-like structure, or be hanging from either side of the tail. The Kreostas will try to get hunters off by violently shaking its tail around, by running and jumping around and by slamming its tail into walls or the ground.

Taxonomy

 * Order: Saurischia
 * Suborder: Theropoda
 * Family: Ceratosauridae
 * Subfamily: Placodermosauria
 * Genus: Kreostas
 * Species: K. armatodermus

Kreostas is a large Brute Wyvern which is found inhabiting several arid regions and is considered the apex of the Glassy Sands. Its closest relatives, besides its Subspecies found in forest regions, Timber Kreostas, are thought to be the likes of Barroth and Brachydios.

Habitat Range
Kreostas are found inhabiting a wide range of arid regions which include the Dunes, Desert, Sandy Plains, Wildspire Waste, Gorge, White Lake, Glassy Sands, Barren Basin, Salt Plains and Cracked Canyon.

Ecological Niche
Kreostas are large, powerful Brute Wyverns which have a position very high in the food chain if not at the top thanks to their size and strength. Kreostas can easily prey on the likes of Apceros, Cephalos, Genprey, Rhenoplos, Kestodon, Psittacodon and Topox. Larger monsters like Kulu-Ya-Ku, Anggiralos, Great Eagle, Sodanoga, Cephadrome, Daimyo Hermitaur and Desert Seltas can also fall prey to this Brute Wyvern due to its strength. Even some monsters as large and strong as Barroth, Rathian, Copper Blangonga, Plum Daimyo Hermitaur, Ragilodillos, Jorokhios, Cynodama and Nibelsnarf, which is in fact thought to be the favorite prey item of the Brute Wyvern as they've quite commonly been seen taking down the Leviathan.

Despite the Kreostas' strength though, it still has to compete with several equally strong monsters which include the likes of Akura Vashimu, Diablos, Seregios, Tigrex, Fulgur Anjanath, Glavenus, Pirhaktor, Eumurikos, Saguatto, Brumagoth, Tahnastyx, Fangosai and Yudenkyuros.

Kreostas also has to worry about predation from stronger monsters like Elder Dragon-Level monsters, including the likes of Ryatroxos, Xhi Khamaria and Poacher Nerscylla, powerful Deviants, like Blastcommander Teostra, Bloodblade Seregios and Bloodbath Diablos, and the occasional Elder Dragon.

Biological Adaptations
Kreostas are large Brute Wyverns which stand in a way akin to that of Brachydios or Barroth, suggesting a relation between them. It's also quite bulky which grants it a large amount of physical strength, being capable of ripping large rocks out of the ground with its jaws which it can then crush or throw towards foes. It's capable of crushing these rocks with its jaws thanks to its powerful jaw muscles alongside unique teeth-like plates, acting almost as scissors. These powerful jaw muscles allow it to open its jaws surprisingly quick, sucking in surrounding sand before shooting it back out towards threats. Its entire body is covered in thick scales which protect it from attacks while its head is covered in thick, bony armor-plating, making it even more protected from attacks while also being great for slamming into threats.

Behavior
Kreostas are territorial Brute Wyverns, but surprisingly not that aggressive as they've been known to let monsters they don't consider threats to their territory wander around them. However, as soon as they consider them a threat, they'll be quick to attack with ferocity.
