>An interesting part was finding old speculation and theories about the show. A lot were weak or shitposting. Some were not canon but actually kind of cool idea that could work...
from the images that you have posted, ironically the headcanon about Fancy Pants is perhaps the most serious one at trying to explain his existence (and he gave advice to Twilight in the Summer Sun Setback). He still holds an important position over the seasons and certainly Fleur de Lis didn´t have any noticeable copy so her design has remained unique to this day.

The other implication that was aiming quite close(considering the amount of info gathered around those years) is the Discord´s one. The show might not have dealt with this but if he changed Discord with Eris, then he could have foreseen the Nightmare Knights comic (or the pillars arc) with Daybreaker and Nightmare Moon´s origins.
