And as a bonus, she’s the daughter of “a useless, powerless failure.”
Remember when all of the TLJ supporters were so happy that Rey was a nobody? Remember how brilliant they all thought it was?
That was before Rey was retconned again to be the daughter of Palpatine; a pretty big someone.
Well, now get ready for another glorious retcon.

Star Wars Confirms Rey’s Father Is A Failed Palpatine Clone
The Star Wars: The Rise of Skywalker novelization reveals Rey’s father was actually a failed Emperor Palpatine clone the Sith Eternal built.
During the scene in the Rise of Skywalker novelization when Rey is feigning taking part in the Sith Ritual on Exegol to trick Palpatine (right before she passes the lightsaber to Ben), she has visions of her grandfather’s past. This passage in the book reveals after Return of the Jedi, Palpatine “thrust his consciousness” into a clone body. However, “the transfer was imperfect” and members of the Sith Eternal worked tirelessly to engineer a new vessel for Palpatine’s essence. One of these attempts is described as “a useless, powerless failure” who was “a not-quite-identical clone.” While this body wasn’t fit to house Palpatine’s power, it was still able to live and eventually became Rey’s father.
