Rui Jangal, a high-ranking general of the Boazanian Empire, commands authority with his crimson skin, three jagged horns, and a scar slicing across his right eye. His imposing stature—broad-shouldered, solidly built—is accentuated by a military uniform patterned in sharp purple-and-yellow motifs, draped with a sweeping blue cape. A master strategist, he orchestrates relentless assaults against the Voltes team, deploying mechanized beast fighters and psychological gambits, such as engineering a lethal disease to test the Goh brothers’ immunity and confirm their Boazanian lineage.

Unwavering loyalty to Prince Heinel drives his every action, even as he privately questions certain decisions. He executes commands without dissent, enduring arrest and torture after battlefield defeats without faltering in devotion. Alongside Katherine Rii, he forges a pragmatic alliance to thwart assassination attempts by Emperor Zu Zambajil, prioritizing Heinel’s survival above all.

Cornered by the Voltes team aboard Heinel’s vessel, he embraces the Boazanian code of honor, impaling himself on his sword to avoid capture. With his final breath, he discloses Professor Kentaro Goh’s captivity on Boazania and proclaims undying allegiance to Heinel—a death that reverberates deeply through both the prince and Katherine.

In *Voltes V: Legacy*, the live-action iteration reimagines him as Draco, his appearance humanized, stripped of crimson hues and formidable physique. This version amplifies his ruthlessness, showcasing a readiness to target children in tactical strikes, yet preserves his strategic acumen and steadfast loyalty to Boazanian command.

His arc across narratives weaves loyalty, honor, and the grim paradoxes of war into the fabric of his tragedy—a noble bound by duty to an oppressive regime. His choices mirror the empire’s caste hierarchy, upholding the supremacy of horned elites while enforcing subjugation upon the hornless, cementing his role as both enforcer and casualty of Boazania’s brutal ideology.
