Nockturnus

Nockturnus is a new Elder Dragon introduced in Monster Hunter Frontier Ultimate. It is regarded as the final online boss, yet Shanthien owns the final quest.

Description
"Known as Supreme Dragons, Nockturnus instill fear into their prey before hacking away at them with their large wingclaws. They are quadrupedal wyverns, capable of reaching high speeds before breathing fire and using the poisonous venom in their fangs to paralyse opponents."

Nockturnus are Psuedowyverns, like Nargacuga and Tigrex, and use their high speed and stamina to their advantage whilst chasing down prey. They bear great resmblance to Nargacuga, and are often mistook for them. They only differences are their larger posture and more Goa Magara-looking head with a pair of small crests on the top. They also have small wings on their legs, allowing them to glide easily to dive at prey from the skies.
