Espinas is a Flying Wyvern introduced in Monster Hunter Frontier Season 2.0. Espinas is physically similar to a Rathian, but alongside scales its body is covered in hot pink spikes full of venom and rough green armor plating. A long, pink, venom-filled horn protrudes from the front of its head, in a similar fashion to Monoblos. Venomous 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.
