Known as the "Artillery Beetle," The Revolvidont (Ruh-vawl-vi-dawnt)is one of the first large monsters to be classified as both brute wyvern and neopetron. Due to its living in the harsh environment of the volcano, it has evolved a unique ability: two cannon-like attachments placed alongside its horn. It fires energy gained from ingesting exploding rocks commonly found in the area. The capacity of blasts it can hold is relevant to how old it is. A fully-grown Revolvidont can have a capacity of twelve(six on each side), while a younger one can carry only six(three on each side).
