Cleopatra Corns leads the Cleopatra Corns Group (Cleopatra D.C.), a financial conglomerate wielding immense influence over the U.S. economy, rivaling the federal government's power. Inheriting leadership at a young age placed her at the organization's helm. Her personality blends a carefree, adventure-seeking spirit with a strong sense of duty; she frequently voices a desire to vacation in exotic locales rather than manage corporate duties, yet consistently intervenes when others face peril. This duality shapes her approach to both business and personal challenges, propelling her into diverse global escapades.

She demonstrates kindness, forgiveness, and notable bravery in high-stakes situations. These traits emerge during missions like extinguishing Saudi Arabian oil well fires, protecting a telepathic android girl named Sara from mercenaries, and recovering stolen artifacts such as the Crystal Pharaoh diamond. Her methods are unconventional and resourceful, exemplified by directly appealing to U.S. President George H.W. Bush for authorization to use an ICBM to smother an oil fire or prevent a nuclear missile launch. She maintains a cheerful, witty demeanor during crises, enthusiastically greeting New York City while racing through traffic. Her attire often features stylish, revealing outfits reflecting her bold and energetic persona.

Professionally and personally, Cleopatra relies on a close-knit team: her pragmatic assistant Suen provides stability and counters her impulsiveness, alongside key allies Nacky, Shorty, and Marianne, collectively termed her "four aces." Together, they confront corporate espionage, kidnappings, and technological threats orchestrated by rival conglomerates and arms dealers. Cleopatra's leadership involves hands-on engagement, including combat and using rocket packs. Her youth occasionally leads to naïve decisions, balanced by her team's experience. The narrative focuses on camaraderie and mentorship, particularly her protective role towards Sara, without exploring romantic relationships.

Across all official media, including the three-episode OVA series adapting the manga, Cleopatra's background remains consistent: depicted as a teenage heiress thrust into corporate leadership, with no detailed exploration of her upbringing or family history. Her adventures span international locales like Nice, France, and the Rocky Mountains, emphasizing high-speed action, technological thrills, and comedic espionage. Stories involve high-risk situations—plane crashes into skyscrapers or space shuttle sabotages—but avoid explicit character development, maintaining her as a static, energetic protagonist focused on immediate challenges rather than long-term growth. Her ethnicity is noted as Black in source material, though visual depictions in animation occasionally lack consistency.
