Duke Zaki

The chief inspector of Emperor Zambajil, and one of few who knew about Zamabajil's betrayal to Lagour and the Boazanian throne. He is well known to deliver bad news to the emperor from his scouting, thus many executions ordered by the Emperor was a result of his reports. Zambajil sent him to Earth to report on Heinel's progress, but discreetly wanted him to ensure Heinel's death at the hands of Voltes V. He plotted with Zuhl to have Heinel pilot a beast fighter, while at the same time leaked information to Big Falcon about the beast fighter's weak points. His plan backfired when Katharine overheard the plot.

Heinel ordered Zuhl to reinforce the weak points, and in mid battle the beast fighter destroyed Zaki's nearby ship with him inside. (Source: Wikipedia)
