Question: are kovu and scar related?
Answer: Kovu is claimed to be the youngest son of Zira, who is a close follower of Scar; his two older siblings are Nuka and Vitani. He was apparently born at some point during Scar's reign, as Scar hand-picked him to be his successor. ... However, Scar merely adopted him, and Kovu is of no relation to Scar.
