(I was unsure whether this belonged here or on the board for the first movie, since it is about that movie but concerns characters from Simba's Pride.)
Basically, I have been wondering why Zira and her similarly-thinking lionesses never appear in the first movie; they look quite different from the normal lionesses, so they would have been rather easy to pick out of the background scenes if they ever showed up in them. Perhaps a better question is why they did not interfere in the fight at the end of the movie on Scar's behalf if they were loyal to him? Zira blames Simba for Scar's death, so logically she must have been around to see at least part of the fight in order to make that assumption. And yet, from what we see, she was not there. Obviously, the real reason is that she didn't exist as an idea when the first movie was written, but can you come up with an in-universe reason for why she and the other Outsiders would be absent?
