Drago holds the Dragon position among the twelve Eto Rangers, having earned fifth place in the zodiac race that assigned their roles. He stands as the team's tallest and most composed member, consistently demonstrating wisdom and reliability that makes him a frequent choice for mission backup support. His abilities encompass weather manipulation, riding a white cloud for transport, and wielding the "Adult Drop" crystal orb to trigger his transformation.

Activating the orb unleashes his draconic might, transforming him into a giant European dragon. This form grants him the power to breathe fire, generate hurricanes with his wings, and retain his magical abilities, significantly boosting his combat effectiveness. His dual mastery of physical combat and potent magic cements his role as the team's "Genius Bruiser."

Drago shares a close friendship with Lydia, the photojournalist; this bond endures even after Lydia's soul merges with Kirinda, the mechanical pegasus used by the Rangers for interdimensional travel. His personality is defined by stoicism and pragmatism, often positioning him as the "Only Sane Man" who provides level-headed crisis solutions—such as prioritizing Princess Aura's defense over immediate team reunification, trusting Bakumaru would grasp the tactical necessity. His calm demeanor contrasts with the impulsiveness of teammates like Bakumaru or Pakaracchi.

Visually, his design incorporates a distinctive turban and scarf, drawing visual cues from Piccolo in the Dragon Ball franchise. During the series' climax, Drago is among the first Eto Rangers killed by Nyanma's forces. His expertise extends into medicine and engineering, reinforcing his value as a versatile, multidisciplinary team member.
