Legiana is a slim, primarily beige-colored Flying Wyvern characterized by its leaf-like wingtips and striped skin patterns. Legiana's head is topped with a pair of antenna-like fins which are attached via a thin membrane to the back of its neck. It has bright yellow eyes and powerful legs ending in piercing talons. Its face, tail, feet, and wingtips are a dark navy blue, and its body is covered in striped patterns of the same colour. The ends of its wings are separated into four distinct flaps which overlap each other when folded, and it's tail has three retractable fins on the left, right, and dorsal. Legiana has star-like shapes on the back of its wings. Its back is also dark blue.
Legiana is able to emit a chilling wind from its body, which dulls its prey's ability to escape. It flies with extreme precision and agility, using its talons to grab its prey straight out of the air. Its legs are strong enough to throw even medium-sized monsters such as Paolumu considerable distances once they are in its grasp.
Legiana is known to live in the highest peaks of the Coral Highlands. It is an apex predator here, hunting prey of all shapes and sizes from the skies.
