Night Wing, also known as Drago Wing, operates as the field commander for the Dragozaur forces under Diamond Ryugu's leadership. His creature form manifests as a prehistoric bat, granting him aerial mobility during missions. A key subordinate, he regularly confronts the Dino Knights in combat, frequently engaging Dino Ptera in aerial battles.

He possesses the ability to drain an opponent's life force, functioning like a vampire to weaken enemies through direct energy absorption. This capability was notably employed against Dino Ptera in one encounter, though not consistently used afterward. Despite his command role, he suffers frequent defeats and humiliation, with his failures escalating to comedic levels as the conflict progresses. His operational responsibilities include direct leadership over Dragozaur grunts.

Unwavering loyalty to Diamond Ryugu defines his character arc. This allegiance persists even when he faces punishment for questioning decisions or mission failures, enduring disciplinary actions like Diamond Ryugu's breath weapon. Early narrative hints suggested potential treachery against Diamond Ryugu, but this remained unexplored; subsequent portrayals consistently reinforced steadfast loyalty. Night Wing participates in combat and strategic operations throughout the main series and OVAs, with one OVA episode centering on him.

His character undergoes no significant development or redemption across official media. He meets his demise in the series finale, crushed alongside other Dragozaurs under a collapsing structure during the climactic battle.
