Mini Knight is an orange insectivore dragon that assists the Lion Clan in tracking Drago Knights and other Dragon Empire members. It wields distinct abilities: flight, offensive twin electric horns, an extendable tongue, and specialized sensory power to detect Dragon Empire forces. The dragon spontaneously appears to the main protagonists during the series, integrating into their team.

Its primary function involves supporting heroes by leveraging its sensing ability to locate threats, providing early warnings or identifying hidden enemies. During missions, it uses its extendable tongue and electric horns in confrontations, occasionally employing its electric capabilities against allies—particularly protagonist Ken—for comedic effect. This establishes a recurring dynamic of lighthearted interruptions in tense situations.

Mini Knight communicates through repeated phrases or vocalizations. Beyond combat, it exhibits a dietary preference for consuming Dragon Knights, extending its role into biological interactions with enemy forces.
