Vitani

Vitani is the (former) secondary antagonist of The Lion King II: Simba's Pride. She is the daughter of Zira, the older sister of Kovu, and the younger sister of Nuka. She is the current leader of the Lion Guard.

Background
Sometime in between the events of The Lion King and The Lion King II: Simba's Pride, Vitani, along with her mother, brothers, and the rest of the Outsiders, was banished from the Pride Lands, for supporting Scar.

Personality
Vitani is something of a tomboy, likely from growing up in such an inhospitable environment. As a result, Vitani is portrayed as loyal to her mother's cause, tough, and prickly, who has a tendency toward making sardonic taunts or sly remarks. Vitani is aware of her own intelligence and loyalty (that is, in comparison to the rest of her family). Vitani is shown to openly support Zira's plan to make Kovu the next king, aware that Nuka is bull-headed, bitter, and unstable. Vitani does seem to show genuine care for Kovu's safety, becoming irritated toward Nuka for leaving him on his own, and again when she excitedly says "Kovu, what a guy!" in Zira's number. As an adolescent, she sees the error of her ways, and becomes the next outsider, after Kovu, to rejoin Simba's pride.

Physical appearance
Vitani bears a strong resemblance to her mother, but she is differentiated by a tuft of hair on her head, freckles, blue eyes, dark eye rims, dark pink nose, and a less prominent jaw. As an adolescent, her ears are striped with black. However, this feature was not present as a cub and appeared intermittently after it was introduced. Vitani's front claws are, like the rest of the Outsiders, constantly unsheathed. Later she get the Mark of the Guard on her shoulder after Kion appointed her as the new leader of the Lion Guard.

The Lion King II: Simba's Pride
Vitani is seen first as a young cub, arguing with her brother Nuka over Kovu. She points out that Nuka's failure to babysit Kovu will get him in trouble, and scoffs at his claim that he could be a better leader than Kovu. When Zira returns with the wandering Kovu, Vitani greets him and challenges him to a fight. She later approves of Zira's plot to kill Simba by taking advantage of Kovu's relationship to Kiara.

As an adolescent, Vitani and Nuka are tasked with setting a wildfire in the Pride Lands while Kiara is hunting. The two gather fire from the elephant graveyard and quickly set a large blaze. This interrupts Kiara's first hunt and forces the princess to flee, which allows Kovu to rescue Kiara and eventually enter Simba's pride. She is later seen spying on Kovu and becoming dismayed when she witnesses her brother sparing Simba's life when he could have taken him from behind. Vitani quickly informs her mother. Zira is angered and plots an ambush of Simba, in which Vitani takes part. In the course of the fight Vitani notices Kovu's attempts to defend Simba so she kicks him into a boulder and knocks him out to end his interference. When Nuka is crushed by logs which fell from the dam, she rushes forward to see her brother and witnesses his death. Along with Zira, she is shown to mourn Nuka's death, but her feelings on Kovu's betrayal are not shown.

Vitani is shown to take part in a battle against the Pridelanders, planned by Zira as an attempt to take the throne by force. She momentarily taunts and then fights Nala but is defeated with Nala using the flip move she used on Simba in the first film, while Zira deals with Simba. Kiara and Kovu intervene, and Kiara argues that the two prides should stop fighting and come together, as there is no difference between them.

Vitani is the first to understand the truth of Kiara's words. She surprises both Zira and Kovu by being the first to rejoin Simba's pride and makes an attempt to convince her mother that it's time to stop fighting. But Zira is angered and sees Vitani as a traitor. Zira threatens to kill her own daughter as well as Simba's pride, which shocks and disgusts the other outsiders enough to join Simba as well. She later joins Pride Rock following the death of her mother and lives the remainder of her life with the rest of the lions.
