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 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.
Malfestio superficially resembles an owl. Its body is covered in blue plumage with a grayish belly, a yellow collar, and a white face with a small beak and red eyes. On its head are long tufts that point back and are tipped with yellow. There are hints of yellow on its legs that end in scaly feet that have two talons and one small vestigial toe. Its wings have bright blue membranes. Along its wings are long blade-like claws. Its flattened tail ends in a three-pointed shape.
From its feathers Malfestio can produce yellow scales that disorient prey and put them in a confused state. It can produce an ultrasound beam that can easily put prey to sleep. The claws along its wings are usually hidden but are revealed once the Bird Wyvern becomes enraged. In rage mode it will begin to use these claws as weapons.
Kirin are most famous for their horns, as they are incredibly sharp, yet surprisingly fragile. A strong Silver Horn is said to be one of the most powerful and valuable of Kirin horns. The Kirin's horn is present in both males and females. Kirin also have incredibly tough hides, and they are beyond the sharpness of most weapons to damage. This is because Kirin's fur is by nature incredibly strong, and it is very tightly packed, effectively forming a suit of very flexible armor around the creature. The white/blue coloration of its hide is something of a mystery, though it appears to be also covered in scales.
Kirin appear to be relatively peaceful and passive creatures, yet they are quite capable of launching a powerful barrage of lightning attacks on their foes. Using their extreme agility, Kirin can literally run circles around their opponent, getting in close to gore an enemy with their horn, only to quickly dart away and prepare another assault.
It resembles a giant, tailed gorilla with pink fur, a hippo-like head, and long front claws. The spike on its head is actually hair that the Congalala has smoothed into shape to signify that they are the pack leader. Congalalas are surprisingly intelligent beasts.
Just like their adult form, the Agnaktor, they have the remarkable ability to tunnel through solid volcanic rock. Uroktor are distinguished by their reddish-purple skin, which protects them from both the sweltering heat and volcanic predators.
Young Pokara are carefree and open to predatory attack. They wander around playfully and despite having fluffy baby seal like fur are already fully capable of swimming seemingly effortlessly. This carefree and playful behavior even leads them to playing with and following hunters even after they just got done killing members of their own species. They are known to mimic the behavior they see hunters doing such as waving or aggressive looking behavior. In some cases they even attempt to talk to hunters through this just ends in a bunch of odd sounds.
A large, wombat-like Fanged Beast. Its ears are long and highly sensitive, and its face features a beak-like mouth along with small red eyes. A Lagombi's belly is made of a low-friction material and is shaped so that it can slide upon the ice like a sled. It is covered in a thick fur coat to keep it warm in its sub-zero homeland.
Aquatic female monsters. Ludroth form "harems" around large males, gathering in territories designated as breeding grounds. They're known to be extremely aggressive towards outsiders, so caution is advised when treading in their territory.
