Leona guards a shrine preserving ancestral white lion hides, including that of Kimba's father Caesar. Her familial ties shift across adaptations: she is Kimba's cousin in the original manga, his elder sister in the 1966 anime, and his aunt in the 1989 series *The New Adventures of Kimba The White Lion*. She exhibits species-atypical features like bat-like ears and whiskers, with appearance varying—white fur and blue eyes in 1989, tan fur and purple-blue eyes in 1966. In the manga, a pygmy village reveres Leona as a goddess. She relinquishes leadership to Kimba upon his arrival, though tensions flare with Kimba's mate Lyra over his choice to return to the jungle. The 1966 series highlights her stubbornness and pride in safeguarding the ancestral hides. She features in two episodes: "The Mystery of the Deserted Village" and "The Day the Sun Went Out," where she is initially presumed killed by the panther group "The Black Four" after being trapped in the shrine but survives. The English dub alters this, showing her captured by panthers with Kimba hesitating to rescue her due to past criticisms. In the 1989 series, Leona serves as Kimba's aunt and high priestess of an abbey, revered by humans and animals who hand-feed her. She pressures Kimba to stay for safety but ultimately accepts his departure. Poachers capture her in episode 16 ("Freedom"), and she dies in the two-part episode "Sacrifice," killed by hunter Ham Egg during Kimba's rescue attempt. These episodes were undubbed in English releases. No additional canonical appearances exist in films, OVAs, or other spin-offs.
