When Disney acquired Lucasfilm in 2012, the House of Mouse did away with any published material that George Lucas personally didn't have a hand in crafting, specifically Episodes I-VI, The Clone Wars series from Cartoon Network, and the Son of Dathomir comic arc published by Dark Horse which was based on an unproduced Clone Wars script. Other than that, 40 years of expanded universe material was regulated to "Legends" status and no longer considered apart of the main canon set in a galaxy far, far away. Needless to say, some dedicated fans were a little miffed at the effective erasure of their favorite storylines and games, and to this day still regard the older stories as their own personal headcanons whether they conflict with any of the officially published Star Wars content or not.
Going beyond previously published material are even more popular fan theories that fall in line with breadcrumbs that have been laid out through the films and TV shows that just make sense even if they were never followed through (looking at you Darth Jar Jar).
This is a collection of Star Wars headcanons. Vote up the headcanons you think should be real!
Palpatine Planted Visions In Anakin's DreamsPhoto: Star Wars Episode III: Revenge of The Sith / 20th Century Fox
From Redditor u/olka0207:
Anakin's vision of Padme dying was imposed on him by Palpatine (her begging "Anakin, please - help me") in order to make it easier to make him turn to the dark side by manipulating his worst fear and his love for Padme.Canon worthy?
Palpatine Waited To Return Until Luke Was Confirmed DeadPhoto: Star Wars Episode IX: The Rise of Skywalker / Walt Disney Studios Motion Pictures
From Redditor u/RexBanner1886:
Palpatine had Snoke lead the First Order, and remained so secret for so long, because he was terrified of Luke. He only revealed himself when he had a year to be be assured that Luke was dead. This is so obvious and elegant a plot point that I assume/hope it's part of the official continuity already. Exegol was somehow shrouded from the light side of the Force - so much so that Yoda and the ghosts believe Palpatine is gone. Otherwise they're too sanguine and criminally negligent when they don't tell Luke that Palpatine is alive.Canon worthy?
Leia Learned From Alderaan When Helping Build The New RepublicPhoto: Star Wars Episode VIII: The Last Jedi / Walt Disney Studios Motion Pictures
From OriginalTrilogy user Ed Slushie:
Because of the destruction of Alderaan, Leia was incredibly paranoid about putting too many resources on any one planet. That’s why the Republic capital rotated between planets, that’s why the Resistance base was off-world before there was any imminent threat, and that’s why the Resistance’s allies were “scattered in the Outer Rim” in The Last Jedi.Canon worthy?
Palpatine Killed Padme In The EndPhoto: Star Wars Episode III: Revenge of The Sith / 20th Century Fox
From Redditor u/Purple-Yin:
My head-canon is that [Sheev Palpatine] was involved.
Look at it from Sheev's point of view – you've spent years grooming this one guy to be your apprentice, then the idiot goes and gets themselves beaten so badly that even with the panacea of Bacta they're going to look like a KFC chicken the rest of their lives, and that's only if they survive, which is far from a given.
Is Sheev the kind of man that relies on chance? Is he even the kind of man to rely on just one contingency plan?
No, he'd have multiple back-up plans in place to save the life of his heir-apparent.
My head-canon is that he relied on the bond between Padme and Anakin and used it to transfer her life energy from her to him, which is why we didnt see her die around the same time that he fell, but the exact time he was healed.
