Mandi, also known as Dan'l Baboon, is a wise and aged baboon who serves as a trusted mentor and father figure to Kimba in the anime Kimba the White Lion. He is one of the older residents of the jungle and carries the experience of many years as a leader of the baboon troop. His background includes a past victory over a rival named Sandi in a fight for leadership, a conflict that resurfaces when Sandi returns seeking revenge. This history shapes Mandi's role as a guardian of the jungle's order.

Personality-wise, Mandi is patient, level-headed, and deeply protective of Kimba and the other animals. He often offers counsel based on his long life, though he can be stubborn or grumpy at times. His primary motivation is to ensure the safety and harmony of the jungle community, and he supports Kimba's vision of peace between animals and humans. As Kimba grows into his role as a leader, Mandi gradually steps back, acknowledging that his own strength is waning and that the younger generation must take charge.

In the story, Mandi functions as a key supporting character. He provides guidance during critical moments, helps Kimba navigate challenges, and occasionally engages in combat when necessary. His relationship with Kimba is one of mutual respect and affection; he treats Kimba almost like a grandson. He also has a close bond with Kitty, Kimba's sister, whom he also protects.

Over the course of the series, Mandi shows development through his acceptance of aging and his willingness to pass on responsibility. He learns that true leadership sometimes means knowing when to let go. His notable abilities include his vast knowledge of the jungle, his strategic thinking, and his physical strength, which, while diminished, is still formidable when the situation demands it. He is also a skilled fighter, as demonstrated in his confrontation with Sandi. Mandi's wisdom and loyalty make him an indispensable ally in Kimba's journey.
