Green Nargacuga are emerald green in color, unlike their Nargacuga and Lucent Nargacuga. These monsters are known to be very active during the day hours as opposed to their nocturnal relatives who wait for nightfall to hunt.
Green Nargacuga are at the top of the food chain and easily capable of killing Aptonoth, Bullfango, Bulldrome, Gargwa, Moofah, and Slagtoth. They will also occasionally prey on Wroggi, Jaggi, and their larger counterparts. Yet these predators compete with equally deadly competitors such as Zinogre, Rathalos, Rathian, Plesioth, Royal Ludroth, Deviljho, Gobul, Lagiacrus, along with Brachydios.
The most noticeable thing about Green Nargacuga is its mottled green fur. This allows it to camouflage in its environment easily. Green Nargacuga is well adapted to heavily forested areas. It can move easily through dense vines and branches thanks to its razor sharp wings. Compared to Nargacuga, Green Nargacuga are known to get bigger though are still quite agile. In fact, Green Nargacuga are known to be a lot more agile than Nargacuga. Even its spiky tail is different compared to its cousin. This monster's spikes have a special property to them that allows for them to knock out prey easily.
Green Nargacuga are highly aggressive and bloodthirsty, and it will achieve whatever ends to get its prey. However, it is well known for sleeping and recovering in tree branches to avoid becoming vulnerable to ground-based predators. This new found aggression is due to them hunting mostly at day.
