Nuka

Nuka is the oldest (and slightly neurotic) child of Zira, and half brother to Kovu and brother to Vitani. He has a straggly black mane and appears small and weedy, and is often tormented by termites. His voice was provided by Andy Dick. Nuka means "smell" or "stink" in Swahili.

The film hints but doesn't explicitly state, that Nuka is Scar's son by how resentful he is of Kovu's position as Scar's heir, despite not being related. It was Scar's wish that Kovu be the next king, although Nuka believes that as the eldest, he should be king. Conflictingly however, after his death, Zira asks Scar to 'watch over her Nuka - if he was the son of Scar, it is likely she would have said our Nuka(though when Kovu rescues Kiara Nala says "your" and not "our"). He constantly tries to please his mother and carries out what Zira commands along with his sister Vitani. He eventually dies after being crushed to death by some logs while pursuing Simba up a log dam in an attempt to get Zira's attention. Zira pushes away some logs and is kind to Nuka for the first time in the movie before he dies. Zira blames Kovu for Nuka's death and slashes Kovu across the face, leaving him with a facial wound identical to Scar's. Before his death, Nuka serves primarily as a comic relief character. An example is when he and Vitani were supposed to light a fire in Kiara's hunting area; he accidentally surrounds himself with fire. In a similar manner to Scar and Mufasa, Nuka is jealous of his younger brother and his position as heir.
