- "Kovu... I was wrong. You belong here."
Kovu is the son of Zira and the adopted son of Scar. He is also the half-brother of Nuka and Vitani. He was originally intended to be named Nunka and be the son of Scar, but this was changed as this would make him Kiara's cousin. Instead, he became Scar's adopted son and heir.
Kovu is a brown-colored lion with a dark brown mane and tail-tip and a muscular build. His eyes are emerald green with yellow scleras. As an adult he has a scar over his left eye that he received from Zira.
The Lion King II: Simba's Pride
- "Oh, haven't you met my son, Kovu? He was hand-chosen by Scar to follow in his pawprints, and become King!"
- —Zira to Simba
Kovu first appears in the movie when Kiara tumbles into him from falling off a log. Kovu reacts aggressively at first but soon begins to tease Kiara for being "daddy's little girl". As the two wander to a body of water they are attacked by crocodiles. The cubs evade the crocodiles and begin to play, but are interrupted by Zira and Simba. The two confront each other before picking up their cubs and leaving.
Later, Zira yells at Kovu for being friendly towards a Pridelander. Kovu tells his mother that he thought Kiara could become friends with him. Zira berates him at first, but then realizes that gaining Kiara's trust would be a great way to infiltrate Simba's pride.
Zira trains and conditions Kovu until he is a young adult. When she deems him ready, Zira sends Kovu out on his mission to kill Simba. Nuka and Vitani help by starting a fire while Kiara is out on her first hunt. Kovu is able to save Kiara from the fire and gain the trust of the Pridelanders.
Later that night, when the lions fall asleep, Kovu appears in Simba's nightmare. In the nightmare, Mufasa is slipping down into the gorge. Simba tries to help him, but Scar appears on the ledge, mocking and cackling. After Mufasa falls, Scar morphs into Kovu. Kovu then grabs Simba's arms like Scar did to Mufasa, and lets go. While Simba is falling down into the stampede, he wakes up from his nightmare, panting.
The next morning, Kovu prepares to attack Simba while he is drinking from the water hole, but Kiara interrupts him to begin the hunting lesson. The pair soon stumble upon Timon and Pumbaa who are trying to chase some birds away from their favorite feeding site. The two lions roar, scattering the birds. They all chase the birds until angering a crash of rhinoceroses. In escaping from the rhinos, Kovu and Kiara accidentally kiss.
That night, Kovu and Kiara lie under stars and look at star formations. This leads them to offhandedly talking about Kovu's past. Kiara starts to nuzzle him when he expresses his fear of becoming like Scar, but Kovu leaves when he is unable to tell her his true intentions. Rafiki intervenes and takes them to a place called Upendi, which means "love" in Swahili.
As they venture back to Pride Rock, Kovu has Simba on his own. Now seeing a better life with Kiara in the Pride Lands, he refuses to attack him. Vitani waits for Kovu to attack, and reports back to an angry Zira when he doesn't.
The next morning, Kovu resolves to confess to Kiara his true reasons for coming to the Pride Lands and that he has abandoned the plot. However, before Kovu can do so, Simba takes Kovu out for a walk through the fire-ravaged lands. As they walk, they discuss the true nature of Scar, but they are ambushed by Zira and the Outsiders. Zira congratulates Kovu, but Kovu panics as he realizes he inadvertently completed the plot he abandoned. Kovu attempts to save Simba, but one of the Outsiders knocks him into a rock, rendering him unconscious.
Simba is attacked and falls into a gorge where a log dam is holding back the river. Simba climbs the log dam to safety and Kovu has a chance to attack him, but doesn't. Nuka, wanting to impress Zira, climbs the log dam and manages to grab Simba's ankle, but is killed when some logs dislodge and crush him. Zira blames Nuka's death on Kovu and slashes him across the face, giving Kovu a scar resembling Scar's. As Zira demands to her son to admit his responsibility for killing his brother, Kovu's stands up to his mother for the first time and runs back to the Pride Lands, where he is promptly exiled by Simba.
Kiara, distraught, runs away to find Kovu. The two meet in the grasslands and proclaim their love that transcends their pride's rivalry. Kovu wishes to run away with Kiara to start their own pride. Kiara refuses, saying that they must return to try and unite their divided prides. They both run back to the Pride Lands, crossing the log dam that has now been weakened, attempting to stop a fight between the two prides. Kovu and Kiara stop the fight, but Zira leaps at Simba. Kiara knocks her aside and the two tumble into a gorge where Zira refuses to take Kiara's paw and falls into the river and drowns.
The now united prides return to Pride Rock where Kovu and Kiara are married with him becoming her prince consort. With order restored, Simba, Nala, Kiara and Kovu roar out across the kingdom while the spirit of Mufasa praises his son for his wisdom.
- Kovu is the only Outsider with permanently extended claws.
- He was originally scripted as the son of Scar, but realizing the incestuous undertones this would have had with his romance with Kiara (as Kovu would have been her first cousin, once removed), it was scrapped and clarified that he had no relation to Scar, and was his adopted son.
