It has black scales, black fur and nightmarish red eyes, giving it the look and style of a predatory black panther. Its dark, feral appearance suggests that it may mainly be a nocturnal predator. This wyvern has been sighted within the Great Forest at both night and daytime, the Jungle, and also the Old Swamp. When it's in Rage Mode, its eyes glow bright red and leave a trail of reddish lines when Nargacuga moves. Also, its tail erects large spikes which can be flung and linked up with its attacks for devastating hits. Their vertebrae and tail muscles are extremely flexible, making the tail of Nargacuga also prehensile. Its tail is also its most powerful weapon. The scales at the end of the tail can also be shaken to produce rattling sounds similar to that of a rattle snake.
Like Yian Kut-Ku, they are surprised by the shock of sound (Sonic Bombs, Barrel Bombs, etc.) which will make them enter rage mode as soon as they recover.
Nargacuga's face can be broken, as can its wings be cut. If Nargacuga's tail has been damaged enough, it can be cut off, but only during a state of Rage, this way of tail cutting is changed in Monster Hunter Portable 3rd, now the tail can be severed when not in rage mode. It is also immune to Pitfall Traps unless it is in Rage Mode or put to sleep.
Nargacuga has the ability to attack with almost every part of its body, mainly its bladed wings and its spiked tail. Its head can be used for biting, similar to Tigrex. Its bladed wings are used almost for the entire battle and deal high damage. Its tail tip, which can be cut with a white bar of sharpness or above, is extremely dangerous. When in Rage Mode its tail spikes will protrude until it gets out of it (Although they will protrude when it uses tail slams and it shoots tail spikes). Nargacuga also has extremely strong muscles that let it jump long distances and tall heights.
Nargacuga is a careful and cautious monster. It is very easy for it to sneak up to a hunter. Nargacuga lives in dark places that it has adapted to. It rests on high trees that are hard to reach, or maybe can't be reached, so hunters can't catch it by surprise for capturing it. Nargacuga will wake up when hunters are right in front of the tree due to its natural senses.

Flying wyverns that have evolved to live in thickly wooded areas. These sly beasts stalk their prey from the shadows with ferocious speed and dogged tecacity, and their massive tails are as dexterous as they are deadly.

If the tail spikes come into contact with a Large Barrel Bomb, the bomb will detonate.
When Nargacuga is very close to death in the Great Forest, it will rest in the trees in Area 5. It will wake up and come back to the ground once the hunter gets close to it. The same goes for Area 5 of the Flooded Forest and Area 9 of the Misty Peaks in Monster Hunter Portable 3rd, where a similarly large tree lives.
Pitfall traps work only when the Nargacuga is in Rage mode. They work for a greater length of time if it reverts to normal while trapped.
If a loud noise is made (Sonic Bombs, bombs) the Narga will flinch. However it will immediately go into Rage Mode.
If the hunter throws a Sonic Bomb while the Nargacuga is in its Prowler Stance in Rage Mode, it falls over and drops a shiny.
When flinching, it moves 2 steps backward and shakes its head. This is also done by Tigrex.
Upon entering Rage Mode, it will jump horizontally quickly and roar.
Nargacuga can fly off from any part of the area, unlike other wyverns, they must limp to a certain spot to flee.
