Editing Retcon (section)

===In [[Star Wars]]===
*'''Everything''' - well, not ''everything,'' just all material that was not found in the first six movies and Star Wars: The Clone Wars, but only the CGI animated television show and movie (not the preceding 2D animated television show or the Dark Horse comics series).  Although it should be noted that both series came to an unceremonious and sudden end after being acquired by the House of Mouse... not that it keeps them from resurrecting the now-designated "Legends" for newer products. Even then, that hasn't stopped them from picking and choosing what they want to build their own hacked-together continuity.

Notables Rendered Unto Non-Existence:
*Kyle Katarn (and by extension also Jan Ors, his love interest, as well both his disciples Jaden Korr and Rosh Penin). Notable for being a ''double'' retcon, since his opening act, ''Dark Forces'', wasn't canon at release.
*Mara Jade (and by extension the concept of "Hands of the Emperor" plus all of Luke's descendants, starting with their son Ben Skywalker).
*Revan
*Meetra Surik (aka the Jedi Exile)
*Durge as an ancient, near-unkillable alien bounty hunter.
*The KOTOR and SWTOR plotlines and everyone involved.
**Most notably Darth Vitiate, HK-47, Bastille Shan and Mission Vao.
*Darth Talon
*Galen Marek / Starkiller (though it can be argued if The Force Unleashed was entirely canon to begin with, LucasArts explicitly noted gameplay mechanics are not canon even before the Legends continuity was separated, and the TFU story was later given through a comic book)
*A'sharad Hett/Darth Kryat
*Kyp Durron
*Corran Horn
*Wraith Squadron
*Abeloth and everything about The Ones relating to her.
*All of Han's and Leia's descendants (although Kylo Ren <s>rips him off</s> is based on their first son, Jacen Solo).
*The Yuuzhan Vong
*The Sith as a Race. 
*Korriban - it's now "Moraband." It's More Bad.
*[[FAIL|Most of Boba Fett's badassery after he escaped the Sarlacc's stomach]].
*Canderous Ordo
*Nomi Sunrider
*Dash Rendar (Dubiously. His ship sorta gets a cameo in the remaster of ''A New Hope'')
*Ysalamiri (Dubiously.  Thrawn has statues of them in ''Rebels'')
*Exar Kun 
*Leia and Han's continuing Marriage.
*Pretty much everything even remotely awesome about non-movie Sith barring that one illusion of Darth Bane in TCW.
**Some ancient Sith Lords who make up 99% of the aforementioned awesomeness.
*Luke Skywalker's awesomeness.
**Actually, Luke Skywalker not being a loser who almost murdered his 15 year old nephew who desperately needed help for literally no reason but the Dark Side tempting him. Legends Luke forgave his nephew for becoming Darth Caedus even after he murdered Luke's wife (said nephew went through so much shit it is arguably more justified than even Anakin's fall). Guy had a genuinely understanding compassion.
*Gilad Pellaeon
*About 75% of Thrawn's awesomeness, the 25% left made him the only interesting non-Force-using Rebels character.
*Most of the history and lore around the Noghri race (though Thrawn's Noghri bodyguard Rukh appeared, he was killed off in Rebels).
*The eventual peace between the New Republic and the Empire.
*George Lucas's dignity. (South Park called it. True weird facts about history: that keeps being true.)
