Who is Nala's Father? Dark Fan Theory of "The Lion King" Part 2

Nala's father was born sometime during the reign of Simba's grandparents and born sometime around the same age as the future King, Mufasa. As a cub, Nala's father fell from a tree, but was saved by the Lion Guard of his day. Some years after this incident, he mated with a lioness named Sarafina and had a daughter with her named Nala. At some point, before or shortly after Nala's birth, her father either died or left Pride Rock, thus leaving Sarafina as Nala's only parent. Despite his disappearance, he would become the father-in-law of Prince Simba (whom Mufasa betrothed to Sarafina) and would become the grandfather of Nala's cubs, Kion and Kiara
