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 mandibles are covered in sturdy plating, particularly resembling a Carnotaurus ' head. Glavenus's most striking feature is its blade-like tail. The blade-like tail is used in many ways by Glavenus such as keeping the body balanced but its primary use is for attacking. This tail can cut prey in two with a single slash, crack the ground easily, and even block some attacks. Though its tail is already a powerful weapon, it can become more dangerous once heated up. By grinding its tail on the ground or nearby hard surfaces violently, it can ignite the tail, heating it up to high temperatures. While its tail is heated all of its tail-based attacks become more deadly, also allowing it to cut through objects much more easily. Glavenus are relentless and aggressive predators. Glavenus oftens drags its tail across the ground and roars at the foe. 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. Their territory is commonly marked by large gashes on the ground, produced when they scrape their tails along solid objects. Instinct: To defend its territory
