Glavenus is a large Brute Wyvern with dark red scales covering its body. Two rows of blue, bony plates run along its back, going from the eyes to the tail. Its underside is more of a cream color. The main feature of Glavenus's physiology is its huge, sword-like tail. The tail has originally the same color as its back plates, although it will turn a rusty color or a fiery red during the battle. Its hind legs are powerful and muscular, while its front legs are much smaller and mostly useless. The face and jaws are covered in sturdy plating, particularly resembling a Carnotaurus' head, though the arms and proportions are modeled after Tyrannosaurus.
Glavenus is able to sharpen its blade-like tail in its mouth to give itself the ability to create fiery explosions with its tail. These explosions not only give Glavenus much greater range with some of its attacks, but also make them more powerful. Glavenus is also able to breathe fire projectiles from its mouth.
Glavenus are relentless and aggressive predators. Glavenus oftens drags its tail across the ground and roars at the foe, revealing the heat and fire glowing in it's throat. This shows the enemy that it uses fire as a weapon in an attempt to scare them off. Not only are they considered one of the strongest Brute Wyverns, they are even believed to be the smartest ones around.
Glavenus has been seen inhabiting deep forested areas like the Jurassic Frontier and Jungle, arid deserts like the Dunes and Desert, and volcanic areas like the Volcano and the Volcanic Hollow. They can also be found wandering the Tower 3.
Glavenus's Japanese name (Dinovaldo) is a reference to Dinosaur (恐竜), Nova (ノバ), and Halberd (ハルベルド).
