They say that nothing is original in entertainment anymore. That even applies to a franchise as fantastical asStar Wars. Despite the vast galaxy at its disposal, this sci-fi series has reused its share of ideas. These mostly come from the Expanded Universe: a collection of comics, novels, games, and TV shows focusing on corners of theStar Warsgalaxy not seen in the films. Sadly, this was not to last.

ThoughtheClone WarsTV showhad already plucked ideas from these other sources with several liberties, theDisneyacquisition cemented the Expanded Universe as a bunch of alternate tales dubbed “Legends.” The “official” canon now comprised the films,The Clone Wars, and any works that Disney put out themselves. However, the EU boasted too many good ideas to go to waste, and the new additions can’t help but take note. Some might call it laziness. Others, however, are happy to see these great (and not so great) concepts brought back to the fold.

10Darth Maul’s Robot Legs

This acrobatic assassin was just too cool to die inThe Phantom Menace. Not only has he shown up in countless video games, but several comic book writers reinserted him into the original trilogy’s era. The most notable isOld Wounds, where Maul returns with clawed, robotic legs andseeks revenge on an older Obi-Wan Kenobi for slicing him in half.

WhenThe Clone Warsresurrected the Sith Lord years later, the creators lifted his design straight from the comics. They didn’t stop there, though.Star Wars Rebelslater paid homage toOld Woundsby pitting Maul against Old Ben Kenobi. What goes around comes around.

Force Healing in Star Wars: The Rise of Skywalker

9Force Healing

One of the many Force abilities that Rey seemingly discovers on her own is the power to heal wounds. None of the movies established this prior toEpisode IX. Sure,Baby Yodacan do it inThe Mandalorian, but he’s not connected to the films.

The games are a different story. Titles likeKnights of the Old Republicinclude Force Healing as an unlockable ability for those pursuing a Light Side path. They had to give more altruistic players something to compete with the flashy Dark Side powers. Maybe that’s why Rey is so overpowered: she’s secretly a video game character.

Starkiller in Star Wars: The Force Unleashed and the Grand Inquisitor in Star Wars Rebels

8Darth Vader’s Hitmen

Among the more popularStar Warsgames isThe Force Unleashed. In this hack-and-slash title, Darth Vader trains a secret apprentice–“codenamed Starkiller”–to hunt down the remaining Jedi across the galaxy. Unfortunately, this guy was just too powerful to bring into the new canon. After all, he can demolish entire Star Destroyers and even best the Emperor in a duel.

Thrawn in Star Wars: Heir to the Empire and Rebels

Enter the Inquisitors. Prominent antagonists in bothStar Wars RebelsandJedi Fallen Order, these assassins fulfill the same function as Starkiller: pursue Jedi on Vader’s behalf. They’re simply not as strong and undergo extensive brainwashing beforehand. Can’t have them getting any funny ideas about rebelling.

7Grand Admiral Thrawn

Set after the original trilogy, theHeir to the Empirenovel needed someone who could fill the power vacuum left by Vader and the Emperor. It found that in Grand Admiral Thrawn. This methodical commander was a master strategist and part-time art collector, devoting himself to understanding the culture and mindset of his enemies. This enabled him to more effectively crush them, and it makes himone of the more refreshing villains in the Expanded Universe.

Although the sequel trilogy negated these tales, the animation folks knew a great villain when they saw one. That’s why they brought Thrawn back inStar Wars Rebels, making him the Big Bad of Seasons 3 and 4. Plus, original author Timothy Zahn has returned to crafted new novels featuring the character. Looks like the red-eyed stepchild of the Blue Man Group has seen a resurgence.

The Emperor in Star Wars: The Rise of Skywalker and Dark Empire

6The Emperor’s Cloning Scheme

When Emperor Palpatine returns from death inThe Rise of Skywalker, the writers never give a concrete explanation. The villain himself simply chalks it up to Dark Side ability, but one of the Resistance soldiers suggests cloning.

This wouldn’t be the first time the Emperor has tried it. TheDark Empirecomics see the Sith Lord transferring his consciousness to several clone bodies. He apparently cooked these up as a contingency plan to achieve immortality. Somehow, that’s less silly than what the movie churned out.

The Nightsisters in the comics and Star Wars: The Clone Wars

5Nightsisters

Originating in theCourtship of Princess Leianovel (not counting the sorceress in the second Ewoks movie), the Nightsisters are a band of female Force-users dwelling on a foreboding forest planet. Although their witchlike aesthetic and tribal culture have remained relatively consistent, their path to the new canon is a little hazy.

TheClone WarsTV show first resurrected the Nightsisters as full-on villains in the Nintendo DS tie-in game,Jedi Alliance. This was during the first season’s airing. In Season 3, however, the creators seemingly ignores the game and reboots the witches as a largely neutral coven that’s eventually wiped out. This image seems to have stuck since playersencounter their remnants duringJedi Fallen Order. Isn’t that nice? The writers brought back the Nightsisters just to kill them.

4The Look Of The Clone Wars

BeforeThe Clone Wars, there was simplyClone Wars. In 2003,Lucasfilmcommissionedanimation darling Genndy Tartakovskyto create a TV serial about this fictional conflict. Using his stylish visual storytelling and penchant for slick action, these three-to-five-minute segments showcased various Jedi Knights leading the Republic’s clones against the Separatists' droids.

FollowingRevenge of the Sith, George Lucas created the computer-animatedClone Warsthat most fans know today. Although ithad a heavier focus on dialogue, he suggested the creators use the previous show in crafting the new one’s look. That’s why it has a similarly stylized, blocky aesthetic. In essence,The Clone Warsowes much of its identity to Tartakovsky.

Such nonconformists exist all over the franchise. Quinlan Vos of the comics andKnights of the Old Republic’s Jolee Bindo are a couple of examples. Many fans have also labeled the films' Qui-Gon Jinn as one due to his disregard for the Jedi Council. The most recent Grey Jedi isAhsoka Tano, the former apprentice to Anakin Skywalker who left the Order. Whether she maintains that moral balance remains to be seen in her upcoming show.

2Replacing Clones With Stormtroopers

One plot thread in the currentBad Batchshow deals with this changing of the guard. To cut costs, the Empire stops using clones for their military after the Clone Wars. Instead, they rely on recruits. This retroactively explains why none of the original trilogy’s Stormtroopers have Kiwi accents.

PastStar Warsproducts have offered a different explanation for this shift. 2005’sBattlefront IIhas the cloners on Kamino breed a new army to fight the Empire. After putting down this revolt, the Emperor would understandably opt for an in-house military, albeit one that can’t shoot straight.

1Han And Leia’s Kids Turning To The Dark Side

Way to go the predictable route! It turns out that Kylo Ren, the sequel trilogy’s main villain, is actually the son of Han Solo and Princess Leia. Originally trained by Luke, young Ben turned toward a darker path and headed a new Empire. That alone is cause for déjà vu, and it doesn’t help that its outfit is a dead ringer for Darth Revan’s.

The comics and novelsgive Han and Leia three children: Jacen, Jaina, and Anakin. All of them accomplish several heroic deeds over the years, but Jacen eventually succumbs to the Dark Side. This leads to conflict not only with Mom and Dad (as seen in the films, but also his brother and sister. It takes sibling rivalry to a whole new level. Needless to say, that’s a bit more interesting than “Reylo.”
