Espinas is a Flying Wyvern introduced in Monster Hunter Frontier Season 2.0. It is known to inhabit the Great Forest and will be encountered at the beginning of HR31 as your urgent quest.

FrontierGen-Espinas Render 002


Espinas is physically similar to a Rathian, but alongside scales its body is covered in hot pink spikes full of poison and rough green armor plating. A long, pink, poison-filled horn protrudes from the front of its head, similar to Monoblos. Poisonous thorns also protrude from its body, wings, tail, feet, and head. Its body, tail, and feet are bigger and more muscular than those of other Flying Wyverns. It has four pink claws upon its feet. Red-orange veins will appear when it is in its enraged state, similar to Tigrex.


Espinas has the ability to shoot toxic fireballs that cause Poison and Paralysis upon impact. In addition, most of its physical attacks cause poison status as well. Espinas also has the ability to charge at great speed whilst ramming with its horn.


Espinas is an unusually passive Flying Wyvern. In the wild, it can almost always be found sleeping. Even when disturbed and woken up, it still responds disinterestedly to any attacks, casually walking back and forth whilst relying on its thick hide to protect itself.

However, if enough damage is dealt to Espinas, it will become enraged. When this occurs, it becomes much faster and more brutal, charging aggressors down, ramming them with its horn, and shooting toxic fireballs.


Espinas can usually be fought in the Great Forest, although there have been much rarer sightings at the Tower.

Other Non-Subspecies Forms

Hard Core (HC) Espinas

FrontierGen-HC Espinas Render 001

In terms of appearance, HC Espinas is largely similar to normal Espinas, though all its thorns, claws and horns are a brighter shade of yellow, and tinged with pink on the tips. Its legs are also more strongly developed, and peculiarly, its eyes are light blue.

HC Espinas is known for its increased speed over its normal brethren; its unique homing charge attack is especially powerful for this reason. In addition, it is more capable of combining its attacks - for example, shooting out five fireballs, then flying backwards whilst shooting the final toxic blast.
