I think Mheetu deserves a good story. So here's what I was thinking:
Mheetu, only a young cub, stood up to Scar when he ruled the Pride Lands. Scar went after Mheetu but, luckily, Sarafina found a way to get Mheetu safe. Mheetu was forced to leave the Pride Lands to escape Scar. He was not able to survive on his own until he ran into another cub named Kala.
