Kuroshen

Kuroshens are powerful elder dragon level Fanged Wyverns that appear starting from High Rank and onwards.

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. It can also consume adamant seeds and might seeds that it has stored in its pouch to buff its attack and defense. It gains extra speed and dragon elemental infliction when it consumes dracophage bugs. If the pouch isn't broken and Kuroshen is in a tired state, then Kuroshen can consume honey that is stored in its pouch to instantly get out of its state of tiredness.

Attacks
Swift Roar: It will scrape its feet and then lunge out a large bellowing roar: turning its head from left to right.

Uprear Roar: It will stand upright briefly and then lunge out a massive bellowing roar: swiping its head from left to right and then crashing its paws down.

Maw Slam: It will rear up slightly and then smash either its left or right maw at whichever hunter is in front of it.

Backwards Maw Slam: It will stand upright briefly before flexibly turning its upper body and then smashing either its let or right maw at whichever hunter is behind it.

Headbutt: It will take a step backwards and then headbutt hunters either in front of it or will turn itself to perform a headbutt to the side of it.

Hipcheck: It will rear its side to the direction of the hunter and then hipcheck: hitting hunters. Slide Hipcheck: Same as the hipcheck but uses an animation that's more akin to Leviathans hipchecks than Barioth's.

Rolling: It will leap and then drop itself to the ground and then start rolling its body to either the left or the right of itself as an attempt to hit hunters that are distant and on the side of it.

Quill Leftover Rolling: Same as the rolling attack but leaves the dragon element-clad Quill's behind which then explode over time. Maw Swipe: It will lunge either its left or right arm and then swipe its claw in front of it.

Quill Shootout: It will jump its back legs upwards and then spin itself around swiftly for a split second: unleashing several quill's in various directions (similar animation to Tobi-Kadachi's spin move). Hit by the quill's inflicts Undrea.

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.

Maw-Stand Sway: It will rear its left arm upwards and then slam it to the ground which uplifts its body in a hand-stand fashion, after a few seconds it will swing its tail in 360 degree before going back to its standard hand (maw)-stand position and then slamming its body to the ground which inflicts Quake.

Soiled Shootout: brown gas will start to unveil from its mouth and then it lunges to unleash a steaming breath of foul gas. Inflicts Soiled.

Dragon Immovable Charge: Similar to the regular Immovable Charge attack but now clad in dragon element meaning the attack inflicts Dragonblight now.

Maw-Stand Dragonball: It will do the uplifting hand-stand fashion animation again but then shoot out a dragon elemental explosion which uplifts it in the air: it targets a hunter while in the air and then crashes down: unleashing waves of dragon element from the impact.

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 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. The soiled odour it can produce comes from the extensive periods of time it spends sleeping inside the carcasses of monsters which reacts with the quills to produce a special chemical (undrea properties) alongside contain the soiled odour on their backs. They often raid Vespoid Queen nests for honey and store this honey in their pouches to either be consumed for later or be consumed by its young.

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.

High Rank

 * In this quest in Area 2, the Gammoth is already dead and when approaching Area 2, a cutscene is triggered which reveals the deceased Gammoth and reveals Kuroshen ripping out of the corpse as its alerted by the hunter/s. The next shot has the hunter/s running back and then flashing to back thus completing the quest but with no reward. Kuroshen now up to this point can invade certain missions without the quest tab mentioning it. (Unlocks a legitimate High Rank Gammoth Quest).

G-Rank

 * In this quest in Area 8, one of the Duramboros are already dead, approaching the corpse would have the hunter witness Kuroshen ripping out of the corpse from slumber and thus spotting and attacking him/her. The other one spawns in Area 6 the moment the other one is triggered.
