Nyra can be compared to Zira from The Lion King 2: Simba's Pride, as they have similar personalities and  both of their sons betrayed them. 

The picture is of Zira and her son Kovu... Zira certainly isn't as pretty as Nyra but Kovu is cute when he is young and handsome when he is older! Sorry for any spoilers if you haven't watched The Lion King 2 yet!
