Vitani in The Lion King II: Simba's Pride
Vitani is the daughter of Zira. Her father is never mentioned, but it was possibly Scar. Furthermore, she apparently has the most loving connection to Kovu given her concern about his safety as a cub.
Vitani has a somewhat minor role in the film. Near the beginning, she and Nuka have a brief conversation about Kovu, and a little later she participates in Zira's song "My Lullaby."
As an adult, Vitani is sent with Nuka to light a fire in the savannah so Kovu can save Simba's daughter Kiara. This is part of Zira's plot for Kovu to inflitrate Simba's pride.
During the battle between the Outlanders and Pridelanders, when Kiara reminds Simba that "we are one," Vitani is the first of the Outlanders to realize that the fighting is pointless and cross over to Simba's side.
Trivia
Vitani was originally Shetani, but since the word means "Devil" in Kiswahili her name was changed to "Vitani" which has no meaning.
Although this may or may not be a missed edit, but when the adult Vitani appears on the ledge above Nala, Nala seems to not say "Vitani", but "Vitalani".
