How Would Doc Brown Saves the World tie into Telltale's game in cyclical time?
So, the new short, Doc Brown Saves the World, is out. It's fun, and it provides a funny story on why the gadgets from the second film were never invented. However, doing so has caused some issues that need some fourth dimensional thinking to sort things out.
We know that the Back to the Future universe is cyclical, as seen by Marty seeing himself leaving 1985 at the end of the first Back to the Future film.
In Doc Brown Saves the World, Doc travels to the future and finds out that Griff Tannen accidentally caused a nuclear holocaust in 2045 by uploading a virus to his popular social network, ThingMeme, that was only supposed to flash the word butthead on every device in the world, but ended up short circuiting every Mr. Fusion in the world.
In order to prevent this, Doc needs to prevent the events that caused it to happen. The hoverboard, hydrator, Nike MAG shoes, and hover car made everyone lazy and obese, so people produced a lot of garbage. 100 million Mr. Fusion units were manufactured to turn that trash into fuel, and those one hundred million tiny nuclear reactors are what caused the nuclear holocaust.
Doc prevented those inventions from occurring by 2015 (when the short took place), which prevented the nuclear holocaust. Of course, in cyclical time, it will prevent Doc and Marty from using the DeLorean to hover in the air, or from using the hoverboard. Which will cause huge problems for the events of the films, not to mention the final episode of Telltale's game.
My theory for all issues in the Back to the Future universe is simply that Doc makes sure himself that these events would occur in cyclical time (backed up by the fact that he's worried about Marty getting back to 1985 in the second film, as he's afraid that if he doesn't go back in cyclical time, a paradox would occur).
So the simplest answer seems to be that he simply used the knowledge he had of these devices and created them for himself so that he could put the events in motion in cyclical time personally, since he knows that they (not so much the hydrator and the Nike MAG shoes, but everything else) are needed for the events to play out the way that they must.
What's your theory?
