Summary:
-Brave marks the beginning of the magic age when animals and objects become sentient, also, the witch in the movie travels through doors.
-Ratatouille gets to the time when animals now sentient since centuries ago start experimenting human characteristics.
-UP is the time when humans know that animals "know" things, the device that the dog carries around is the first one to understand animals language. Also, the company called BNL appears for the first time.
-Nemo just gives us an example of a non so sentient animal (Dory) in a world of intelligent ones.
-The Incredibles has that droid giant thing that seems to be very intelligent, also the hero-killing airplane. The machines are supposedly becoming hostile.
-Toy Story shows the resentment from innanimate objects, but also show that they need the human life to live (as toys need a nearby human to be alive). BNL appears again as a giant corporation.
-Animals and objects make a planet of the apes revolution and try to destroy humans, humans use machines to win the war (that's the reason why no other animal is seen after TS2).
-In Wall-E humans are long gone from the planet as the BnL corporation (supposedly a machine corporation) go them out fot stopping the pollution of the planet caused for unbalance, machines now serve their purpose as human slaves, yet they control the planet while there are no humans around (as seen in CARS and PLANES (?)).
-Oil runs out and with no humans the machines die, that's why the world is barren in Wall-E.
-Wall-E saves the humans as he's still emotionally attached to them thanks to his history fascinations.
-The tree at the end of Wall-E is the tree from A Bug's Life, supposedly centuries have passed.
-In A Bug's Life the animals are already 100 in full human mode.
-Animals, machines and humans live in harmony for many years and so...
-Monsters are born by the mix of the three races (!)
-Monsters Inc happens in the far distant future of earth.
-As humans are now extinct, but humans are the source of their energy they create doors for TIME TRAVELLING
-That's "evidenced" by a truck in Monsters Inc being the same as in A Bug's Life but in the latter is destroyed.
-The thing is, Boo is spposedly the "Brave" witch that somehow learned the secrets of "door travel" and taht is supposedly evidenced by a carving of Sully in a piece of wood in her workshop, she also has a pizza planet truck, and the way she dissapears is because she uses the doors for time travel.
Tadaa..!
