To be honest, I think it's about the line of the lion kings. Mufasa being first

, then Scar

, then Simba.
I think it's about the blood line of the kings, and Disney shows us different types of kings. First there is the big, wise, and gentle giant king, Mufasa. Then there is the wicked, scrawny, and shrewd king, Scar. Then last but not least, Simba, who was supposed to be the greatest lion of them all. I think he was more rigid and less easy-going in the sequel though. Then in the end, he finally forgives everything about the past and lets it go.
I think Kopa would have been the next Lion King in the blood line, but because Kiara was in the sequel, she was the Lion Queen.
So I am going to choose "Other". Because it isn't about any lion in particular, it was about the blood line. Though, this is my opinion and I could be wrong. But yes, that's what I think.
