The Pale Man of Pan's Labyrinth (c) Guillermo Del Toro

The Road of Trials
Campbell writes that "if anyone—in whatever society—undertakes for himself [sic] the perilous journey by descending, either intentionally or unintentionally, into the crooked lanes of his own spiritual labyrinth, he soon finds himself in a landscape of symbolical figures" (2004, 101). Del Toro chooses the amorphous space of the labyrinth as the setting for the hero's journey, where Ophelia must undergo a series of tests, tasks, or ordeals that are necessary to begin the transformation. Here Ophelia will engage in a multitude of tasks that are intricately linked to the unsavory elements of the abject, such as rickety insect-like fairies, an oversized slime-spewing toad, and a child devouring a skeletal pale man. In the following image, she is seen crawling through mud, with cockroach-like insects slithering all over her body. Her first mission is to retrieve the golden key from a large, grotesque toad whose ingestion of bugs causes him to grow so immensely that he strangles the life forces of the tree.

Pale Man is a grotesque child-eating creature that appears in the  film.

What makes the Pale Man such a frightening and disturbing element of the film are not necessarily bound to the actions and representations that come with the character while it is on the screen; rather the lasting effect that the Pale Man has on the viewer can be seen as quite profound. The audience is given such little time to fully take in what the Pale Man is that much of his demonic world is left to the viewer’s imagination. We see that the monster clearly escapes from being harmed in any way and must assume that it lived on even after the events of the film concluded, meaning that in some place it is still out there waiting for its next victim. Since so little is given about what the Pale Man is, the audience is left to their own thoughts on how it could ever have come to its lair and where that location really is. The fear that this creates is almost more so than that of the actions of the Pale Man in the film because it allows for the audience to give the monster characteristics that are unique on a personalized basis and can result in the monster being tailored by the individuals’ largest fears.

Pale Man belongs to Guillermo del Toro

I haven't seen the movie (I know I'm terrible T_T) but yeah Pale Man scares meeee XDD
Certain characteristics of the Pale Man may also have been partly inspired by German and Scandinavian folk tales, in which persons or monsters representing the dead (or being dead themselves) are usually portrayed as blind or at least very near-sighted, and often also as child-eaters.

You'll know it's me, I'm the Pale Man in Black

The Pale Man came from Guillermo del Toro’s own imagination. However, the character was heavily influenced by Goya’s painting ‘Saturn Devouring his Son’.

Yeah, I'm doomed to be the Pale Man in Black


During Ofelia's quest to make sure she hadn't turned into an ordinary human, her second task was to get to the Pale Man's lair and retrieve a dagger which was kept locked down there. The Faun warned her not to eat anything from the luxurious banquet served at the sleeping Pale Man's table, and also let her take his pet fairies with her to serve as a guide during this journey. Once there, Ofelia quickly found the dagger with some help from the fairies, but when she was about to leave, she just couldn't resist temptation and ate two grapes from the banquet, in spite of the fairies reminding her not to do so. This, as expected, woke the Pale Man up, who quickly placed his eyeballs on the gaps of his hands and set off to find and eat Ofelia, who watched in horror as he devoured two of the fairies that were accompanying her. As Ofelia rushed to escape, the exit closed seconds before she was able to reach it. She quickly drew another one with a piece of chalk that she was carrying and both her and the remaining fairy managed to escape just in the nick of time, leaving the Pale Man behind.When Oflelia visits Pale Man, he is sleeping in a chair at his dining table next to a warm crackling fireplace. Once there, Ofelia quickly found the dagger with some help from the fairies, but when she was about to leave, she just couldn't resist temptation and ate two juicy plump grapes from the Pale Man's banquet, in spite of the fairies reminding her not to do so. This, as expected, woke the Pale Man from his deep silent slumber, who quickly picked up his eyeballs off a platter on the table and placed them into the eye sockets in the palm of his claw-like hands, to see and immediately set off to find and eat Ofelia.
