In the Jedi Prince series of young-reader novels (1992–1993) by Paul and Hollace Davids, set about a year after Return of the Jedi, a three-eyed mutant named Triclops is revealed to be Palpatine's illegitimate son; he had a son named Ken, the titular "Jedi Prince".
In The Rise of Skywalker's novelization, we learn that Rey's father was a failed clone of Emperor Palpatine. He was initially created to be a vessel to house Palpatine and his Sith power. However, Rey's father proved incapable of doing so.
We know for a fact that Sheev Palpatine, Darth Sidious himself, had one son. Whether biological or the result of cloning, this son seemed to be a complete unknown to viewers and the galaxy until The Rise of Skywalker.
In the context of the story, Snoke is a "genetic strandcast" created by Emperor Palpatine to serve as his proxy in power. Snoke, whom Abrams called "a powerful figure on the dark side of the Force", was introduced as the leader of the First Order and master to the sequel trilogy's primary villain, Kylo Ren.
The novelization of The Rise of Skywalker reveals that Rey's father was a nonidentical clone of Palpatine.
Regardless of how favorable either of these decisions have been received, the canon has firmly established Rey as a Palpatine, but with her own chosen decision to carry on the Skywalker name instead.
The Emperor's son sired a child of his own, Rey, his daughter who inherited Sidious' power in the Force, unlike himself.
One could theorize that he bore a child through some sort of space artificial insemination, or something closer to what we've seen in canon Star Wars material. In the canon comic Darth Vader No. 25, it is revealed that Palpatine somehow used the Force to manipulate midichlorions to impregnate Shmi Skywalker.
If not, the only logical explanation is that Jar-Jar is a member of the Sith. There are many theories surrounding the enigma that is Jar-Jar Binks. The most agreed upon theory, started by Reddit user Lumparoo in 2016, is that Jar-Jar is a powerful Force-user conspiring with Darth Sidious.
Snoke Was a Strand-Cast Created by Palpatine
Emperor Palpatine created Snoke to be his proxy through which he could regain his power. Although Snoke was bio-engineered in a lab on Exegol, he was a strand-cast, not a clone.
The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren: leader of the Knights of Ren, champion of the First Order, and apprentice to Supreme Leader Snoke.
Kylo Ren Dies
While Rey is ultimately the “Skywalker” who rises in the culmination of the Sequel Trilogy, The Rise of Skywalker also gives us the return of Ben Solo, who is brought back to life through Leia's final message of love, Rey's mercy, and Han's memory.
She does not have a baby bump, her hand never goes to her stomach to indicate she's carrying a child, and there wasn't exactly any time for her to have conceived a child with anyone in the course of the film, including Kylo Ren/Ben Solo.
As powerful as Darth Sidious may have been, it's easy to forget he actually seemed afraid of Master Yoda. As seen in Revenge of the Sith, Palpatine initially thought he could deal with the aged Jedi Master - and then, when Yoda proved able to counter the Sith Lord's Force lightning, he fled.
As Kylo Ren himself says in The Rise of Skywalker, he and Rey are bonded not just by their familial legacies (Ren as the grandson of Darth Vader and Rey as the granddaughter of Emperor Palpatine) but by their unique connection in the Force.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi. As the name implies, these Force-sensitives chose to practice the Dark Side, and rejected the Light Side of the Force.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
After the Sith were decimated by the Jedi Knights of a thousand years ago, Bane enacted the Sith rule of two: there would be only two active Sith at one time -- a Dark Lord to embody the power, and an apprentice to crave it.
Rey was born on Hyperkarn in 15 ABY during the rise of the New Republic. Her father, Dathan, was a bioengineered Strand-Cast cloned from the genetic template of Darth Sidious, the Sith Lord who ruled the Galactic Empire as Emperor Palpatine.
Fandom. Question: Did Maul know Sidious was Palpatine? In legends he did. In the darth plagueis novel I'm pretty sure there's a part where maul was reflecting on his master's political machinations and how he is publicly known as palpatine.
Later, Star Wars: The Rise of Skywalker revealed that her grandfather was actually Emperor Palpatine (Ian McDiarmid). It was also revealed that Palpatine was alive, and went up against Rey at the end of the film.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.
Even though Finn is once again Force-sensitive, and tries to tell Rey about it throughout the film, the film ends without the story addressing his abilities. While fans were left wondering about Finn's Force status, subsequent Lego films have confirmed it, and Finn is already on the road to becoming a Jedi.
By the end of The Rise of Skywalker, Rey had become the last known Jedi of the Skywalker Saga. With all that being said, Rey was not left as the last remaining Force-sensitive character.
