'Robin Hood,' 'The Lion King,' And 'Zootopia' Share Same Universe. Fan theory of "The Lion King" p7.

Although many associate Disney with cuddly, talking animals, the studio has only made three movies featuring all-animal casts. These three movies - Robin Hood, The Lion King, and Zoo-topia - actually all take place within the same universe. In this theory, this explains, why there are no humans in zoo-topia. We have created a timeline which shows a period of time from the dark ages of zoo-topia to modern day zoo-topia. It all starts when humans begin experimenting on animals sometime in the mid 2020s. They create intellegent animals. Some of these animals escape because they are intellegent. Now there is a disease which kills of humans and the escaped animals reside in africa. Years before the events of the lion king. So this is simbas great great Eych grandfather. They fight a war with humanity who threaten them. They wipe out there creators and banish them to the farlands(Europe,central asia) and they begin there society. Now here's my proof. Mayor lionheart bares a resemblance to simba that means that they are related. Both of them are great leaders wanting whats best for there people. Lionheart did this.Just not in a very good way. Also if you watch carefully, in the background of robin hood, (there all in the same universe), you can see some of the mountians, that were used in the background of the lion king, and robin hood is full of proof that they are all in the same universe. Anyway after lion king, they begin to adapt and change beginning to stand up like humans, and use some of our technology to better themselves. The reason why there are no birds or reptiles is because they were all weeded out by nature. A couple thousand years later, you have zoo-topia a unsuspecting city, where anyone can be anything, and is the desendents of the people, who commited mass genoicide on humanity. I imagine by this point humans (if there not already extinct) have bettered there technology and really want zoo-topia. Why thought? Because during a great human war possible world war 3 the rest of the world was ruined and africa is all thats left. So i imagine sometime in the near future of zootopia humans will reapear. So basically, Leodore Lionheart, the mayor of Zootopia's fictional city, is actually a descendant of Simba. Scar's demise was the beginning of peace between predator and prey, and Lionheart is attempting to carry on his ancestor's mission. The theory goes on to claim that Zootopia's pivotal fox, Nick Wilde, is descended from Robin Hood and Maid Marian.
