The Devilface is a medium to large sized wyvern that is recognized by its distinct head, which closely resembles that of a devil. It has a broad snout, a protruding jaw, and large, sharp teeth that it uses to tear through flesh. The Devilface is found mainly in the northern parts of the Vache Kingdom, where it roams freely and hunts opportunistically. It is known to be an aggressive predator and will stop at nothing to take down its prey. The Devilface's favorite prey includes large mammals, such as deer, elk, and other reptiles. It is also known to hunt smaller animals, such as rabbits and squirrels, if they are more readily available. The Devilface is an opportunistic hunter, and it will often scavenge for food if it cannot find any prey to hunt. It is a solitary creature and prefers to hunt alone.

The Devilface is a fierce predator and uses a variety of hunting tactics to take down its prey. It will often use its sharp talons to swoop down and grab its prey, lifting it off the ground and taking it to a safe location to eat. It also uses its powerful wings to create a gust of wind that can knock its prey off balance, making it easier to attack. One of the Devilface's greatest strengths is its speed and agility. It is an incredibly fast and maneuverable flier, making it difficult for its prey to escape. Additionally, its sharp talons and powerful jaw allow it to tear through flesh with ease, making it a formidable opponent.

However, the Devilface has several weaknesses as well. It is not particularly durable and can be injured easily if it is not careful. Additionally, its aggressive nature can sometimes lead it to take unnecessary risks, putting itself in danger. Despite these weaknesses, the Devilface is a fearsome predator and is not to be underestimated.
