Justice League: 10 Insane Fan Theories You Need To See

2. Green Lantern Won't Appear... Because He's Parallax

It's still not known whether Green Lantern will make an appearance in Justice League, but with a Green Lantern Corps movie on the horizon, it won't be long until the green-clad character shows his face.

However, one fan thinks that he definitely won't be in the film, and has an explanation as to why.

This theory states that twenty years ago, Green Lantern - following the destruction of his home town, Coast City - turned evil, destroying the Green Lantern Corps and becoming a supervillain under the name of Parallax. This would mirror Emerald Twilight, the comic-book storyline, in which these events actually happened.

As a result, Green Lantern/Parallax will not be in Justice League, but would show up in the sequel as a villain. This would allow the Green Lantern Corps movie to be a prequel that follows the Emerald Twilight storyline.

The Reddit user who laid out this theory stated that Warner Bros would need to get people interested in Green Lantern again, after his disastrous 2011 outing. They'd need to make a completely different Green Lantern movie and make the character completely different too, in order to distance this version from the Ryan Reynolds version.

And what better way to do that than to make him evil?

There's already a nod to the destruction of the Corps in the latest Justice League trailer, with Steppenwolf mentioning (via voiceover) that there are "no Lanterns."

So, if there is indeed a Green Lantern-shaped hole in that movie, we could be seeing a very different Hal Jordan when his solo DCEU outing lands within the next few years.
