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.
A brute wyvern that can bring its mighty tail down on foes like a massive sword, decimating them in an explosion of flames created from the volatile components found in its scales. If its tail dulls from accumulated soot, a Glavenus will use its fangs to resharpen it.

Monster Hunter World: Iceborne
A brute wyvern that wields its heavy blue tail like a blade. It grows hotter and more keen with each strike until it glows red.
Glavenus can only spit lava after sharpening its tail with its jaws.
Glavenus's lava spit will leave behind a spot of burning material that deals continuous damage to hunters before exploding. This damage can be alleviated by wearing the Fireproof Mantle.
When it is enraged and its tail is red hot, Glavenus can slash either rightwards or leftwards after performing its tail slam attack. The direction in which it will attack can be predicted by watching the way its blade shifts after the first impact.
