Scar Ate Mufasa
We’ll be the first to admit that this next theory is somewhat less compelling than others on this list. In fact, this brand of Disney theory takes real-life information about wild animals and real locations and then draws conclusions based on that. It’s far from scientific, but hey. This theory scarily says that Scar probably ate Mufasa’s body after murdering him. This is based on the skull that the villainous lion is seen playing with, and some real-life lion factoids.
