Thanks for the comments guys! I will try and think of an even better combination. Although I have to admit that this is probaly the closest match that would have a Vitani/ or a Kovu.

Although there are many theories about this, especially with Tama and Chumvi, their mother is Zira. Even though adopted children call adopted parents "mum" and "dad", they call her mother because she IS their mother. Not every lion can have different appearances, and just because they do look similar, it doesn't mean they are related.

There is no real proof of Vitani and Kovu's parents. This makes the fans come up wtb different combinations. This is a well thought out combination but with each combination there is some holes. Like if Tama and Chumvi are Vitani and Kovu's parents how come Zira raised both of them? And if Tama and Chumvi are the parents of Vitani and Kovu how come Vitani has a pink outlander nose and Kovu has a black outlander nose? If they are the parents then one of both Chumvi and Tama's parent would have outlander noses and Vitani's nose could be a mix of the two. There are other combinations that involve Chumvi and/or Tama but there's no proof. This is very well thought out, and I praise you for that.
