The Last Jedi fan theories are exploding all over the Internet. Snoke's identity is still a mystery, as is Rey's parentage, and just what the hell is Luke's problem? Then there's Kylo Ren. Kylo is the grumpiest Solo, the son of Han and Leia, the nephew of Luke Skywalker, and Darth Vader's biggest fan. There are some pretty crazy Kylo Ren fan theories out there (like he and Luke are the same person), but there are some that are worth considering.
The biggest question is what will come of Kylo. Will he find redemption? Or is he destined to be a monster? Perhaps the answers to those questions lie in his past. Kylo Ren's backstory is a bit hazy, but these Star Wars fan theories claim to have the answer to that and pretty much any question about Ben Solo.
Whatever Kylo's deal is, there's a whole lot of room for speculation. The following theories have the potential to spoil The Last Jedi and beyond, depending on how accurate they are.
Kylo Is An Unparalleled Pilot
Redditor CorsairVI makes a very well-reasoned argument for Kylo Run being the best pilot in the galaxy:
"His grandfather, Anakin Skywalker, was considered one of the greatest pilots around. He was the only human podracer due to being Force-sensitive, blew up a Trade Federation battleship at a young age and displayed his talent for flying through a war zone to save Chancellor Palpatine only to 'safely' crash-land a half-destroyed dreadnought onto Coruscant. As Kylo is a Vader fanatic, there’s a chance that, in order to be greater than Vader, he would continuously hone his flying skills.
His uncle, Luke Skywalker, also became somewhat of a prestigious pilot after he helped destroy the first Death Star. He avoided cannon fire, TIE Fighters and even his own father to, without guidance equipment but by way of the Force, launch the photon torpedoes at exactly the right time into the vent that caused the chain reaction to blow it up. Sure, he got shot down during the Battle of Hoth, but he displayed aptitude on a speeder bike during the Battle of Endor. Luke probably told him the story about the first Death Star which may or may not have given him the drive to try and do something just as prestigious as his mentor.
Then you have his father, the legendary smuggler and celebrated pilot Han Solo, Corellian captain of the Millennium Falcon. Corellians are known for being reckless and daring alongside being considered fantastic pilots, and there’s a saying that 'Corellians have rocket fuel for blood.' No doubt Han would have trained Kylo back when he was still Ben Solo to assist in flying the Falcon at a young age.
Kylo Ren is a half-Corellian, Force-sensitive human with great pilots in his lineage, was most likely taught by Han Solo to fly, possesses a drive to be better than his grandfather and his mentor AND there seems to be a hint of both respect and mocking when he interrogates Poe Dameron and says 'I had no idea we had the best pilot in the Resistance on board' as though he’s really saying 'You’re a good pilot, but not as good as me.'"
Rey And Kylo Are Going To Join Forces In One Way Or Another
Tumblr user mother-of-porgs makes an exceedingly compelling argument that the scene we saw in The Last Jedi trailer of Kylo Ren apparently holding out his hand to Rey is legit. Many have speculated that this is a bit of misdirection, but mother-of-porgs takes a deep dive into movie themes as well as technical elements of filmmaking, like lighting and color, to ultimately conclude that Kylo really is offering his hand to Rey in a show of good faith, and their relationship will become one of "compassion."
They don't go so far as to guess the nature of their relationship, whether it be romantic or otherwise, but they're confident that they will join forces and that Kylo will find some sort of redemption.
Kylo's Lightsaber Recycles Vader's Kyber Crystal
Redditor coool12121212 believes that Kylo was so obsessed with Vader that he searched through the wreckage on Endor to find his broken lightsaber:
"Okay, so we know that Kyber crystals are extremely durable, right? And that Kylo Ren's saber has a cracked Kyber.
So, what if when the DS2 exploded, with all that Kyber powering the laser, destroyed Vader's saber (which he dropped) and caused his Kyber within it to crack because of the sheer force of the Kyber-fueled explosion. Resulting in the crystal falling down to Endor with some of the debris of the DS2. Staying there forgotten...
Until Kylo Ren went there and found it, his grandfather's Kyber crystal. So he of course takes it and uses it to power his own lightsaber. Which can also explain why he's using a cracked one in the first place, since I'm sure he could have found a perfectly normal one with the First Order/Snoke."
Kylo Is Being Manipulated By Snoke, Who's Posing As His Dead Grandfather
Redditor DrAlcoholocaust has an interesting theory about Vader's helmet and ghosts in the Star Wars universe:
"The last time we saw Vader’s helmet was on Endor with Luke during the final sequence of Return of the Jedi, but it is now in the hands of Kylo Ren. I would like to explain how I think he came to possess it, why he turned to the dark side, and how it will play an important role in episodes VIII and IX.
In The Force Awakens Kylo speaks out loud to his grandfather’s helmet. But why? Exposition for the audience? He is crazy? I don’t think so. Kylo believes he is talking to Vader, much in the way Luke talked to Obi Wan throughout the original films. And something is talking back.
But we know from ROTJ that Vader’s force ghost is Anakin and free from the dark side, so why would he be tempting Kylo to 'finish what [he] started'? First let’s figure out how Kylo obtained it.
Luke likely brought the helmet to the Jedi temple where Kylo would later be trained. In the same way that Anakin’s saber called out to Rey, Vader’s helmet reached out to Kylo. It is at this point that Kylo is fooled into thinking he is communicating with his grandfather, but the voice he hears is actually Supreme Leader Snoke’s. It gradually seduces him, teaches him about the dark side, and makes him destroy the temple.
Han Solo said Snoke was manipulating Kylo for his power, but we never see him actually doing any manipulating. It is quite the opposite. He seems to let Kylo operate in any way he wants and barely scolds him for his mess ups. All a part of the plan. I believe it is through Force telepathy that Snoke is controlling Kylo by pretending to be Vader and feeding him lies about the past, the Force, and his destiny in an effort to turn him into a weapon just like Palpatine did with Anakin."
