Malfestio are owl-like Bird Wyverns that were recently discovered by the Wycademy.

Habitat Range

Malfestio have been seen inhabiting the Jurassic Frontier, Deserted IslandPrimal Forest and Ruined Ridge.

Ecological Niche

Malfestio are mid-sized predators that feed on Herbivores, such as young Larinoth and Kelbi. Malfestio also occasionally feed on carrion of dead animals. Though Malfestio are top predators in their own right, they have to compete with other predators like Nargacuga, Tetsucabra, and Glavenus.

Biological Adaptions

Due to the way Malfestio's eyes are positioned, it will rotate and maneuver its head to allow it to see better. Despite looking as though it has normal wings, Malfestio has long sharp claws that are usually hidden while Malfestio isn't using them on its wings. From how they overlap over each other, most wouldn't notice them easily. Malfestio will reveal them once enraged before beginning to use them as both weapons and tools. The claws allow it to fly better yet quieter. Its wing membrane are very unusual compared to other species. If touched, scales will puff out. These scales gather sound and emit a strange echo pattern. Inside its feathers are strange yellow scales that are released when it erects its feathers. The scales put prey in a confused state once inhaled, making prey see images in places where they really aren't. The scales on its body is how it is able to quietly fly in the night sky. Malfestio has a special narcotic liquid in its sleep sac. It fires this liquid at enemies by using ultrasonic vibrations produced by the scales on its webbing to atomize the liquid and spray it at prey.


Malfestio prefer to venture out at night without being disturbed by other threats. Malfestio are known to attack prey under the cover of night. They'll use their talons and wing claws to attack prey. Generally, Malfestio sleep in trees to avoid ground-based threats.
