Kovu

Son of Zira and said to have been taken in by Scar. Kovu's real father is never mentioned in the film. Younger brother of Nuka and Vitani. Kovu has a very similar appearance to Scar and many believe him to be Scar's actual bona fide offspring. It could be that the truth that Scar is Kovu's father was shrouded in mystery until it was lost, or it could be that Scar was flattered by an unrelated young lion cub who looked so much like him. Kovu was chosen by Scar to be the successor to the fraudulently claimed throne at Pride Rock. After Simba returned to the pridelands and banished those loyal to Scar, Zira continued to train Kovu to be future king of Pride Rock. Kovu went along with the plan at first but then began to fall in love with Kiara and and decided he wanted nothing to do with his mother's evil plot. After finally gaining Simba's trust, Kovu and Kiara were formally joined to each other as lifetime mates by Rafiki.
