Bubu, alternatively known as Claw, functions as a primary antagonist throughout multiple iterations of the Jungle Emperor/Kimba the White Lion franchise, with distinct portrayals across adaptations. In the 1965 anime series, he emerges as a rival to Panja, Kimba's father. A duel costs Bubu his left eye, cementing lasting enmity. After Panja's death, he attempts to seize jungle control and eliminate the young Kimba upon his return. This version portrays him as a temperamental tyrant commanding henchmen, though flawed execution often foils his schemes. He develops an obsessive infatuation with Kimba's friend and love interest, Kitty, intensifying his vendetta. Despite his antagonism, Kimba voices willingness to accept him should he reform. The 1989 series, *The New Adventures of Kimba the White Lion*, reimagines Bubu as a more calculating and brutal foe. His backstory with Panja, including the eye injury, remains consistent, but his romantic interest in Lyre/Kitty is absent. He operates as a strategic mastermind alongside allies like the panther Toto and a vulture, displaying lethal ruthlessness toward cubs. This iteration introduces pivotal development: late in the series, Bubu allies with Kimba and other animals against a shared existential threat, culminating in a sacrificial act to save Kimba. The 2000 short film *Jungle Emperor Leo: Hon-o-ji* depicts Bubu framing another character for destroying birds' nests to sabotage Kimba's leadership. Exposed, he battles Kimba and loses his remaining right eye, resulting in complete blindness. This adaptation explicitly establishes him as Kimba's uncle, adding a familial layer to their conflict. Other media feature limited or absent appearances: Bubu is unseen in the 1997 film *Jungle Emperor Leo*, while the 2009 special *Jungle Emperor Leo: The Brave Can Change The Future* includes only a brief flashback of his duel against Panja. His manga role aligns with early anime portrayals, showcasing his rivalry with Panja and Kimba, partnership with Toto, and eventual blinding after losing his second eye to Kimba. Physically, Bubu typically appears as a dark-furred lion with a black mane, sharp teeth, and a visibly damaged or scarred left eye. Earlier color manga depictions show tan fur with a white underbelly. His consistent personality traits include ambition, domination-seeking, and deep-seated resentment toward Kimba's lineage, supplemented by descriptions of an underlying inferiority complex regarding Kimba's family.
