Question: are kovu and simba cousins?
Answer: This of course would make Zira Scar's partner and Nuka and Vitani Kovu's siblings. However, this naturally caused much commotion amongst the creators of Lion King 2 because this would make Simba and Kovu cousins. ... That is what happened after Zira and Scar raised Nuka, Vitani, and thier adopted son Kovu.
