- Mobile Suit Gundam: Kycilia Zabi was the last member of her family standing for a reason. Fully aware of her elder brother Gihren's moral depravity and mismanagement of the conflict with the Earth Federation, Kycilia uses the One Year War as a cover for a coup d'etat against him, gathering resources and allies, while undermining Gihren's loyalists. Upon discovering through Colonel Killing's betrayal that Gihren had infiltrated her faction and was preparing to frame her for treason, Kycilia moved swiftly, leaking Char's identity to Gihren's fake conspirators and transforming a sham plot into an actual revolt against his rule. Aware that Zeon could no longer win the war, and that the Federation would never make peace while her brother lived, Kycilia journeyed to A Baoa Qu and, on finding out that Gihren had murdered their father, executed him for patricide and assumed command of what was left of Zeon. Killed when Char Aznable unpredictably betrayed her, Kycilia was nevertheless the only Zabi, or indeed, Zeon Admiral, with both a realistic appreciation of their circumstances, and the ruthlessness and will to act accordingly.
- Mobile Suit Zeta Gundam: Paptimus Scirocco, "The Man from Jupiter", is an elusive mercenary and Titans Lieutenant who graduates to taking over the organization. A brilliant tactician both in and out of a mobile suit, Scirocco excels at reading potential in his subordinates and outmaneuvers the Anti-Earth Union Group (AEUG) to capture the strategic stronghold of the lunar city Von Braun. Leaving the day-to-day operations of the district in the hands of his antagonistic superior, Scirocco divulges the man's schemes to the AEUG and arranges for his death to gain more dominance within the Titans for himself. Forming an alliance with Haman Khan of Neo-Zeon, Scirocco bolsters the strength of the Titans with the Axis military and personally assassinates the Titans leader, Jamitov Hymem, assuming command over the syndicate and blaming Jamitov's death on Haman, rallying his forces to fight against her. Giving a former AEUG pilot he corrupted to his side an eloquent lecture on his ambitions for humanity, Scirocco engages the AEUG personally and reveals he has kept his alliance with Haman to revitalize the strength of his fleet. Even with his armada destroyed by the blast of a colony laser, Scirocco continues to fight series protagonist Kamille Bidan and, in his dying moments, destroys Kamille's consciousness, unrelentingly unwilling to accept his vanquishment. Emotionally manipulative yet charming, charismatic and stylish, Scirocco proves himself to be every bit as brilliantly Machiavellian as he is mysterious.

Invading the Earth before the Federation could recover from the war, Haman occupied huge swathes of the planet, and used the Dublin Colony Drop to terrorize Federation officials into surrendering to her, all while employing sheer force of personality to mask her myriad personal issues and hold the backstabbing house of cards that was Axis-Zeon together. Betrayed at the zenith of her power by Glemmy Toto, and faced with internal rebellion by his supporters, Haman quickly moved to quell the descent, meeting Glemmy in open battle. Confronted by series' protagonist Judau Ashta, Haman was persuaded that humanity did not, in fact, need her jackboot on its throat to stop them from killing each other. Coming to grips with what she had become, Haman killed herself in the name of giving the world a better future.
