One of the highlights of The Force Awakens was the introduction of Finn (John Boyega), a stormtrooper who defects to join the Resistance. Along the way he has a sort of epic bromance with rebel fighter pilot Poe Dameron (Oscar Isaac), making sexuality just one subject of many in the subsequent myriad theories about Finn. As The Last Jedi releases, the Internet is abuzz with new Star Wars fan theories, which of course means more speculation about FN-2187, AKA Finn.
Finn's role in both The Force Awakens and Episode VIII showcases him as an important part of the Star Wars universe, and there is plenty to already know when watching the latest Star Wars films. The mystery around Finn opens up all sorts of possibilities for who he is, where he came from, and what he is meant to do.
Here are a number of theories about Finn from Star Wars that will have you laughing, crying, grinning, and grimacing - perhaps all at once. There are potential SPOILERS for The Last Jedi, if anyone happens to be correct in their hypothesizing.
VoidPursuer believes that Finn is the son of Mace Windu, who apparently died at the hands of Emperor Palpatine, but perhaps not:
"My SO was reading an article and was like, 'Hey, you might like this.' She told me that George Lucas has confirmed that Mace Windu survived and I nearly sh*t myself... In the article it says he has been laying low just like Obi Wan and Yoda did.
Now that brings me to Finn.
I wouldn't say that just because Mace Windu is the same race as Finn that he is obviously his dad but, them being the same race is a good foot in the door. (However I guess that's why I always hated the Lando Calrissian theory, but this has some better backing).
Why would a stormtrooper who was put through serious brainwashing and conditioning, break away from the First Order to do what he thought was right? Why was he the only one? ... I believe it's because the Force is strong in his family and he had a minor awakening just like Rey but a little less. Kylo Ren sensed him on Jakku. They have shown him wielding a lightsaber (albeit not entirely well) and he doesn't know who his family is. It would make sense that he and Rey ran into each other.
And finally just for fun. Think about the name Finn Windu. It sounds pretty great."
Rert0Gear makes a case that Finn will become a Jedi, in large part because the universe is dangerously low on space wizards:
"[The Force Awakens] has shown us parallels between [Finn], Kylo, and Rey in their characters and backstories. So why not finish it off and have [Finn] become a Jedi like his two counterparts? There is speculative evidence within The Force Awakens that he is Force sensitive. The destruction of the Hosnian system, him 'awakening' mid-battle, picking up weapons he has never used before rather quickly, and the heavy marketing of him with the saber... this series seems to have an actual plan, and isn't just being thrown together by Lucas because he got a green light to do another installment. So I'm going to assume that every shot best serves the story and is building towards where things are going.
I am also going to assume the writers/marketing team have common sense. Having a character run around for 1/3 of the film with the most iconic weapon in movie history, only to never have him become a Jedi or use it again, decreases the value of the weapon because it becomes common use and not solely associated with a special class. Never mind the fact that it is no longer canon, but I have seen people state there are examples of people using lightsabers who are not Jedi in the EU. The question then is how many common moviegoing fans would know that? Without using his fights with TR-8R(Nines) and Kylo to serve a greater purpose for his story later, they just seem out of place in the series. If the sole purpose was just to cover for Rey, they could have had Finn try to pick up the saber in the scene with Kylo, only to be brushed aside by a single stroke.
So let's say he does become a Jedi, how could this benefit the series? Well for one it helps with the fact that we are running extremely low on Jedi in the universe. Luke's failed academy pretty much sets us all the way back to square one post-Revenge of the Sith. I think they are looking to avoid anymore perceived copied story elements from the OT, having a second Jedi could avoid that. Assuming Rey is Luke's daughter, this allows for someone without the last name Skywalker to have Force powers in the series. Going forward it gives a little more credence to the idea that the Force has 'awoken' by having multiple beings in the galaxy have the Force. Kind of The Legend of Korra-style, but with Jedi instead of air benders.
It makes rebuilding the order a storyline that could be followed in an animated series. Should Luke die by the end of the series, we only have Rey to rebuild. Plus there are like 7 Knights of Ren, and somebody is gonna need to deal with those dudes while Rey fights Kylo and/or Snoke. There are options for Finn to be trained by Luke, [or] Rey when she finishes training, or he could go Kyle Katarn [and] slowly learn it by himself."
"Why not have Finn infiltrate the Order and start turning other troopers against the First Order?" asks Retr0Gear. "His tale could be a very compelling story and might be able to sway some of the weaker-minded troopers. Talking about how they were all stolen from their families and robbed of their humanity could work well onscreen and really put him at odds with Phasma and Hux."
The theory is perfectly plausible - perhaps too plausible.
Savagesugarcube's title for his theory says it all: "Finn's dead friend was a spy who intended to die in battle to make Finn question the First Order."
"When the stormtrooper that was obviously friends with Finn got shot, what did he do? He wiped his blood on Finn's helmet. Blood. This isn't very significant until you think about the fact that blaster bolts are laser projectiles. A small scale bolt like the one from the blaster from Poe's weapon should have cauterized the wound.
Now, you could make the argument that Chewbacca's bowcaster had made Ren bleed, until you take into account the scale of a bowcaster bolt. It is much larger and is made to tear material apart, different than a blaster. So, back on track, what if Finn's friend was actually an undercover rebel spy? He did not want to kill innocents or was maybe close to exposure, so he decided to traumatize Finn, someone he had grown close to. Maybe he even made Finn sympathize slightly with the rebellion, which would explain why he easily got involved with the rebellion.
He essentially passed the torch to someone who knew probably just as much if not more about the First Order on purpose. He had cut his hand before the battle and made sure it bled heavily. He was planning to make sure he got killed and show Finn the injustice of the First Order."
