Archduke Zag
Archduke Zag is Cadet's evil cousin who took over Swinus 9. When news of Cadet's return reached the planet, Archduke Zag went into hiding and resurfaced to capture Princess Incense. When Cadet and Duck Dodgers followed him to a lava river, Archduke Zag and Cadet fought with laser sabers. When Cadet won, Zag used lava-powered bracelets to conjure a lava monster to attack Cadet. Duck Dodgers and Princess Incense converted the lava monster's energy source and Archduke Zag was defeated. Zag was voiced by Clancy Brown.
