Hellblade Glavenus is a Deviant of Glavenus. Hellblade Glavenus's true identity is a Glavenus individual that has taken in extreme amounts of rich soot into its body, which has made its fire both stronger and explosive.
Glavenus is a top predator that will relentlessly chase down its prey. Glavenus have primarily been seen feeding on Larinoth, Apceros, and other Herbivores. Despite being a top predator, Glavenus has to compete with other large predatory monsters. Monsters like Rathian, Malfestio, Agnaktor, and Zinogre are potential threats for Glavenus. Though it has many predators to compete with, Glavenus are quite deadly themselves.
Hellblade Glavenus have many of the same adaptions as Glavenus, however, there is a few differences between them. From it constantly sharpening its tail, Hellblade Glavenus's appearance has changed. This sharpening has led to its scales, shell, and even eyes being discolored. This has also led to its scales and shell being highly explosive if carelessly handled. Hellblade Glavenus's fire sac is also different from a normal Glavenus's fire sac. It not only produces fire, but also a strange explosive powder. Portions of this powder are even found in its mouth, along side with its fire. When it sharpens its tail, Hellblade Glavenus will not only add fire to its blade-like tail, as it sharpens it, but will also add this explosive powder. This gives its tail fiery heat and powerful explosive blast all in one strike. With destructive power like this, Hellblade Glavenus can both blow enemies sky high and incinerate them with explosive flames.
Hellblade Glavenus are much more aggressive than normal Glavenus, even being said to be able to turn whole mountains to ash. This has even led to them being considered to be on par with powerful monsters like Rajang and Deviljho.
