Kuroshen

Physiology
Small sized fanged wyverns that ravage the lands they cross daily and utilise physical strength, fast speeds, sharp back spikes and the  dragon element. Similarly to Savage Deviljho, they become clad in dragon elemental mist when enraged along with the addition of their spikes growing in size, big enough for the fanged wyvern to toss them at hunters, similarly to Kamu Orugaron.

Behavior
Usually doesn't attack those that avoid it but are absolutely ruthless to foes that provoke it alongside when hunting prey. Despite their small size, their physical prowess is phenomenally tough combined with their swift movements against opponents alongside their usage of the mystical dragon element and their overgrown spikes that can be large enough to completely impale small monsters and deep into a large sized foes stomach.

Abilities
Have supreme agility when compared to other fanged wyverns and a thirst for destruction and mayhem to match.

Quill-Twister: Same attack as the Spinning Leap but unleashes quills everywhere. Hit by one inflicts Undrea. Back Slam: It will leap upwards extremely high and then slam its spiked back onto the ground (similar to Hyujikiki). It'll be stuck there for a few seconds before getting back up.

Homing Dragonball: Same as the Dragonball attack but the design of the projectiles looks much dimmer and is larger and it homes in on hunters until either blocked or dodged.

Quill Storm Crashing Dragonball: Does the Maw-Stand Dragonball animation but it then additionally unleashes the Quill Rain with the quills being clad in dragon element while also slamming  downwards to unleash waves of dragon element from the impact.

Habitat Range
Usually lives in colder regions such as Tundra's, Deserts (at night),  Swamps and Snowy Mountains, though they will occasionally travel  to Volcano's or moderate temperature regions such as the Deserted Island when on the search for dragon elemental prey items.

Ecological Niche
Similarly to Rajang consuming Kirin's to gain their electrical abilities. Kuroshen/Jianshiro need to consume dragon elemental creatures to gain them. Most of the time, this falls onto Stygian Zinogres being preyed upon but sometimes weakened Deviljho's get hunted down as-well alongside juveniles ones. They will hunt down full grown adults if hunting with other members of its kind. If in desperation, they will simply track down dracophage bugs for a small boost. Due to them being marsupials, they can pouch not just their young but dracophage bugs which helps them increase their dragon elemental prowess and enable it to dish out even more ruthless attacks on foes.

Biological Adaptations
Quills contain scraps of the deceased monsters they  sleep in which chemically reacts with the properties in the quills: thus its quills having undrea properties to it which it can combine with its teeth and claws to dish out powerful physical attacks alongside make its prey bleed to death without them realising.
