Needs a better villain than the hyenas
The movies had Scar and Zira. The Aladdin series had a whole rogues gallery of villains. I know, it's a kid's show. Well, so was Aladdin.
If we're talking canon with the movies, this should be around the time Zira is grooming Kovu to become her weapon to destroy Simba. Why not include the outsiders that were banished?
