Duker Iq is an officer of the Zanscare Empire serving as a captain of its elite Motorad squadron and an antagonist in Mobile Suit Victory Gundam.
Duker Iq is first seen pursuing the League Millitaire forces, but is unable to stop them from escaping.
Duker Iq later reports to Queen Maria Pure Armonia about BESPA's clashes with the League Millitaire. He uses the opportunity to present his Adrastea-class design of cruiser to the queen, claiming it will quell all rebellion against Zanscare by inspiring fear.
During Operation Giant Roller, Duker discovered he had feelings for his subordinate Renda de Paloma. However, the two do not get to be together for long. During a cease fire between the Earth Federation and the Zanscare Empire, Duker Iq attacked the White Arc. However, his ship's bridge was destroyed by Odelo killing both him and Renda.
An apparition of him with Renda later appears and the two ride into the clouds until they reach a forest with a cabin and disappear.
