Shrek has long been a cult cartoon, and even years after the release of the last part, fans do not stop sharing new theories. One of the most shocking is that Prince Charming and Fiona may be brother and sister. This version may seem incredible, but looking at it from different angles, it becomes clear that it has some basis.
Why might Charming not be the Fairy's biological son?
The first question that arose among fans of the cartoon: why is Prince Charming a prince if his mother, the Fairy, is not related to the royal family? Why then is Charming so sure that he has the right to the throne? Strange, isn't it?
In addition, unlike the Fairy, Charming does not have magical abilities and wings. Moreover, the hero's physique is by no means miniature, he is quite tall and strong, which distinguishes him from his mother.

How Charming Became the Fairy's "Son": The Hidden Truth
Some fans believe that the Fairy was unable to have children, and being very cunning, she devised her own plan. First, she turned King Harold into a toad and made him promise that if he became human again, he would give her his first child.
Of course, they weren't going to tell Fiona about such details. And besides, she hardly knew anything, because even Arthur, the real heir to the throne, was forgotten. There were clearly intrigues going on in the royal palace, so who knows what was really going on there? The kidnapping of a child is not a new plot.
The main trump card of the theory: the similarity between Charming and Lillian
One of the most convincing arguments in support of the theory is the external similarity between Charming and Queen Lillian. Many fans of Shrek have noticed that Charming and Lillian really do look very similar to each other, which raises questions about a possible relationship.

If we compare Charming to Fiona, there are also certain similarities, such as the parting of his hair, the shape of his nose, and the wrinkles on his forehead. This suggests that they may be brother and sister, and that their family ties were hidden behind intrigue and magic.
