Kopa, Simba's fictional son, first appeared in a series of books called The Lion King: Six New Adventures. He looks very much like Simba did as a cub, but has a brown tuft of hair, and the end of his tail is brown. As the books explain, Kopa is a fairly adventurous young cub.
From the release of The Lion King and the release of Six New Adventures, it was generally accepted that the cub at the end of The Lion King was Kopa. But when Simba's Pride was released, fans questioned whether the ceremony and the cub were supposed to be the same at the end of The Lion King and beginning of Simba's Pride.
Even though the cub at the end of The Lion King was obviously male, it is generally accepted that Simba only had one cub: Kiara. However, Kopa has become a marvelled character for Fan Fictions. Some go to the extreme cases such as Kopa ran away or was kidnapped, and no one was allowed to talk about it from Simba's Pride on.
I'm gonna write a page on MLK about this topic, but for now we can just talk about what you guys think of Simba's Cubs.
