Nakarkos is an elusive Elder Dragon that has been reported for many years now. Like Kirin and Yama Tsukami, Nakarkos was put into the Elder Dragon class because it doesn't exactly fit into any other known classes.
Nakarkos have been reported in many different regions by eyewitnesses such as the Jurassic Frontier though Nakarkos are known to make huge bone-covered lairs in caves. These lairs are known as Wyvern's End. Nakarkos are also known to be found in the sea.
Nakarkos easily assert themselves as top predators, no matter what the environment is. These Elder Dragons have been identified feeding on the armored prey, such as Uragaan and Diablos, and even top predators like Glavenus, Brachydios, Agnaktor, Rathalos, Nargacuga, and Lagiacrus. Even monster species capable of flight aren't safe from this monster. The most shocking creatures these Elder Dragons have been found to take down are Shen Gaoren and Ceadeus pups. Other prey includes Hermitaur, Daimyo Hermitaur, and Volvidon. The only real likely things that could potentially threaten a Nakarkos are other Elder Dragons like older Ceadeus, their only known predator.
Nakarkos is able to produce an eerie, blue mucus from its body. This mucus is sticky, allowing it to capture prey and even shoot prey items out of the air. Though this mucus is used for capturing prey, Nakarkos has another use for the mucus. This mucus is used to help prevent bones from corroding, sticking bones together, and to prevent the bones from collapsing. With this mucus, it can make a protective bone armor to protect its whole body from attacks and even use some bones as weapons. Like a cuttlefish, it has sticky tentacles used to drag prey back to its lair. These tentacles are usually covered in bones for protection, ending with a huge skull. But this isn't just limited to skulls. Nakarkos has been seen using various monster parts to attack foes or to kill prey with. Some of these parts are hard to identify due to Nakarkos altering their shapes in order for it to use them. Some parts that it has been seen using is a fused together Glavenus jaw and tail, a Lagiacrus's shell shockers, a Brachydios's pounders, and a Uragaan's chin. These various parts give the appearance that it has "two heads" but Nakarkos's true head is hidden away underground most of the time. When it feels its life is truly in danger, it will eventually reveal its true face. Its true face is cephalopod-like, resembling a cuttlefish. By revealing its face, it can use its bone-crunching beak and use the Dragon Element. Like many other Elder Dragons, Nakarkos has the Dragon Element in a certain portion of its body though it can barely control the element. So to make it easier for itself to use the Dragon Element, it will fire the element from its tentacles and build it up in its mouth before firing a massive beam. This attack is actually very risky for Nakarkos due to the beam sometimes greatly damaging it in battle. To move quickly, Nakarkos has jet propulsion like squids. It uses this to return to its nest at a quicker rate, so it can avoid getting eaten itself.
Nakarkos are gluttons that can eat a whole ecosystem if left unchecked. Due to Nakarkos having huge appetites, they can easily wipe out all life in surrounding areas. Nakarkos have even been reported shooting down airships for food. Though Nakarkos can destroy an ecosystem, it doesn't actually want to do that. It prefers to leave its nest in search of prey so, it still have plenty of food at the environment it is living within. This affects those ecosystems greatly on a destructive level, making it harder for species to thrive in said areas, leaving very few creatures to survive. If the Hunter's Guild finds a Nakarkos' lair, they will immediately send hunters to repel it before it can bring further damage to that ecosystem. However, it is said that Nakarkos will eventually return to said area in order to feed themselves further.
