Franca Dochley, also transliterated as Franka Dockley, is the daughter of the legendary Pirate King Bruce Dochley. Witnessing her father's murder by Madame Marciano three years before the main events profoundly shaped her life. After Bruce's death, Mister became her guardian, though Franca suspected his primary interest was accessing her knowledge of her father's hidden treasure rather than genuine concern for her welfare.

She possesses distinctive pink hair, blue eyes, and often wears a ribbon. Her attire typically includes an aqua dress, sometimes layered with a yellow shirt for warmth. Born on April 9, she carries a pendant entrusted to her by Bruce; this pendant serves as the key to locating his buried treasure of ten billion space dollars on the planet Graceland.

Despite her youth, Franca demonstrates significant practical skills. She is a proficient cook and capably runs the Pirate bar during Mister's absences, known for swiftly and effectively breaking up patron altercations through non-violent means, earning the classification of Badass Pacifist. Her competence extends to actively participating in high-stakes confrontations with the Criminal Guild alongside the Coyote crew, showing resilience and adaptability under pressure.

Her development includes moments of emotional vulnerability concerning her family. A video in Episode 11 highlights her strong resemblance to and affectionate bond with her late mother, Mrs. Dochley. Throughout the journey to secure Bruce's treasure, her initial cynicism about exploitation gradually evolves, reflecting a nuanced shift in her relationships with Mister and the crew, while her core motivation to honor her father's legacy remains central.
