Here's Ahadi, the selfish jerk. His father is Choyo, brother of Mohatu, and his mother is Thema. Why do I call him a selfish jerk? Well, for one thing, in my theory, he gives his own son a scar! I hate this guy personally, and I like Uru much better.
I like your version and your theory! I like to think that Mufasa gave Taka his scar. =P But your theory is cool too! A lot of people like to think that he gave his son his scar, and I think that's an interesting theory. =D
