Jangal Rui

ルイ・ジャンギャル, Draco

The three-horned General sent to Earth with Prince Heinel and Katharine. Fiercely loyal to Heinel while also a wise strategist, he is the one who convinced Heinel, and himself, that the Gō Brothers are actually part Boazanian.

He later chose death over surrender to the Voltes team.
