“Legion” is the brainchild of Noah Hawley, who utilizes a darker stance in telling the story of this psychological drama involving a mutant with immense power but afflicted with a possible mental problem. This style of storytelling appears to be paying off as it was reported that the show currently enjoys a 93.33 rating according to ComicBook.com User Composite.

"Legion" spoilers have been circulating and it is definitely something a lot of Marvel fans want to check out. While the show poses a lot of questions regarding the story of each of its episodes, the one that stands out the most among fans relates to the identity of the devil with yellow eyes.

According to some speculations and "Legion" spoilers, the said devil is a monstrosity that exists in the recesses of David Haller’s (played by Dan Stevens) mind, and lurks along the lines of his most traumatic moments and feeds on them. This nature of the devil tickles the curiosity of fans while, at the same time, striking fear into their hearts in the process.

"Legion" spoilers point to the speculation that the answer, perhaps, can be provided in the subsequent episodes of the show as fans and viewers see the unfolding of events in the series’ story.

Another speculation and part of "Legion" spoilers permeating among fans is that the creature is an original creation made solely for the “Legion” television series. It is observable that the creature does not exist in any of the original source material of the tv series (i.e. Marvel comics). This is also true among some of the show’s supporting cast. Nevertheless, while the devil appears to be an original creation, it seems that it has been based on at least three characters which exist in the original Marvel universe.

Wherever the creature is based on, it appears that it is already one of the most effective characters in the series. It being talked about by fans and viewers of the show is a testament to this.
