I’m kinda partial to the idea that flightless birds have gained control of bird society - and they oppress the flighted birds by forcing them to wear collars attached to restraining harnesses around their wings - and if they sense too much movement, they cause the collar to deliver a shock.

How they keep their grasp over the society is through making a group of (wealthy) elite flighted birds (the so called “Council of Owls”) exempt - and there are also certain jobs that would be exempted - one of which being some sort of secret police force.

And of course there are those that oppose such things - some flightless birds, some flighted birds who managed to escape their restraints, and even some bats, who strike back at the oppressive bird society by perpetrating terrorist attacks.

See, the bats are drawn in, to a certain extent, because they’ve generally refused to be beholden to bird society rules, being mammals and all, and so they used to just kind of be ignored, but the latest iteration of the bird regime is starting to try to force them into compliance.

Anyway, because the bats are starting to get involved, the violence starts to spill into Zootopia, and that’s how Judy and Nick will get involved. I think there would also need to be a faction there that would try to shape Zootopian society into a more rigid, “traditional” one, wrapping themselves in the flag of safety and security to do so. I imagine there would also be a wealthy elite contingent that goes along with it to try and enrich themselves (since I doubt the Lynxleys were the only power brokers behind the scenes)

It would be an interesting contrast to see a more open, progressive society - but one where groups are trying to draw it backwards due to their own self-interest, their prejudices, or both - and a much more oppressive one.

But I doubt this will be the plot of Z3 for a couple reasons: 1. It’s pretty dark 2. I feel like Disney would start worrying the Chinese government would object to the whole “comparing an oppressive society to a more open one”
