When Disney decided to eliminate much of the Star Wars Expanded Universe, they set the stage to freely make the sequel trilogy and other films set before the original trilogy. Unfortunately, this left a lot of characters, especially Jedi on the scrap heap, honored only by Disney referring to those stories as Legends. These Jedi have been lost to history, only occasionally brought back to canon in ancillary tomes as references missed unless a fan looked closely.
There is a large number of Jedi that originated in the various comics, games, and novels. A lot of these were developed during the era of the prequels, but the history of the Jedi was fleshed out, going back millennia. Of course, some of these Jedi are more worthy than others to be brought back into canon.
10 Worst: Juhani from Knights of the Old Republic
The Knights of the Old Republic video game is one of the best Legacy era games. It even added an important element to Star Wars lore with the introduction of Revan, a Jedi that was redeemed from the dark side. Among the supporting characters was a briefly fallen, feline Jedi Knight named Juhani.
Juhani is encountered on Dantooine in a grove she had retreated to after believing she had killed her master. She is terribly two-dimensional with a trite origin as a former slave. About half of the dialogue Courtenay Taylor recorded for the character was cut, making Juhani very limited in her role in the game. It leaves her uninteresting filler that serves only to try and keep the player on the Light Side.
9 Best: Roran Corobb From the Original Animated Clone Wars
The Ithorian Jedi has been canonized, but only in a written guide to lightsabers. His real shining moment is in the Legends animated series Clone Wars, produced by Genndy Tartakovsky. Corobb's famous for trying to protect Chancellor Palpatine from General Grievous at the end of the series.
In the failed effort to get the Chancellor to safety, Corobb lets loose with a force-assisted bellow from his multiple throats. He put up a valiant effort against Grievous and his forces. Ultimately, he fell before the General's vicious attack, as depicted in the animated series and the novel Labyrinth of Evil.
8 Worst: Celeste Morne, the Central Character of the Vector Crossover
The Dark Horse comics spanned millennia across four titles, Knights of the Old Republic, Dark Times, Rebellion, and Legacy. In 2008, all of these titles crossed over in an event called Vector. Jedi Master Celeste Morne was the central character, tasked to find a talisman that contained the soul of a dead Sith Lord, Karness Muur.
The talisman turned people into vicious mindless creatures called Rakghouls. Thousands of years ago, Celeste put herself into hibernation to protect the Galaxy from the Sith Lord. Despite moments of suspense, her story was finite and served only as a distraction for most titles. She even spent over a century in space to keep the galaxy safe before assisting in the overthrow of Darth Krayt.
7 Best: Dass Jennir from Dark Times
Following Revenge of the Sith, Dark Horse released a new series titled Dark Times, set immediately following the fall of the Republic. The first story arc followed former Jedi Dass Jennir as he set out to help his friend Bomo Greenbark rescue his family from Imperial slavery. It ended tragically, with Jennir falling far from the path of the Jedi.
Jennir changed his appearance to hide his Jedi past. His adventures found him with Ember Chankeli who hired Jennir to rid her home planet of a gang that had seized control. Jennir and Chankeli fell in love and she joined him on the run. She was nearly killed, but the pair was rescued by his old friend Bomo and the crew of the smuggling ship Uhmele. His character was so compelling, trying to maintain optimism in an increasingly dark and cruel universe.
6 Worst: Jorus C'baoth from Outbound Flight & the Thrawn Trilogy
Jorus C'baoth first came to fans' attention in the Thrawn trilogy, but not as a Jedi. It was actually his clone that Grand Admiral Thrawn had made a deal with to destroy the nascent New Republic. The clone was quite insane and sought to corrupt Luke Skywalker and Leia Organa Solo and seize control of the Empire, but fell to Skywalker and his new ally Mara Jade.
The original Jorus C'baoth was an arrogant Jedi Master who supported the Outbound Flight project. The project was doomed by the sabotage of aliens led by the future Grand Admiral Thrawn. C'baoth fell to the Dark Side when he gave into anger against Thrawn and was killed when a bomb destroyed the Outbound Flight.
5 Best: Revan, The Mysterious Jedi from Knights of the Old Republic
The twist from the Knights of the Old Republic video game was a fantastic reveal worthy of Star Wars. The player finds out that they are the fallen Jedi and former Sith Lord. The formerly official history of Revan had him completely redeemed and forming a romantic bond with ally Bastilla Shan.
Throughout the game, the player learns Revan's history leading the Jedi against the Mandalorians. Characters in the game hide the truth from the player, but when it's revealed, it's a dramatic moment that sets the game above most other Star Wars stories, rhyming slightly with the original trilogy, but feeling wholly original. While backstory in the Rise of Skywalker makes Revan's existence as a Sith canon, the Legends history remains unofficial.
4 Worst: Cade Skywalker, Luke's Smuggler Descendant
With the comic Star Wars Legacy, fans saw a new protagonist in Cade Skywalker, Luke's descendant. He'd been orphaned by the virtual extermination of the Jedi. He was raised by smugglers and pirates, which is how he makes his way into the galaxy.
Cade too often comes across as unlikeable. His journey doesn't follow the familiar Hero's Journey that so many other protagonists in the various Legends series did. He resists his destiny with the Jedi so many times that every time he embraces it, it means less.
3 Best: Jaina Solo, Han & Leia's Daughter
In the world of Star Wars Legends, Han Solo and Leia had three children. Two were twins, Jacen and Jaina Solo. She became a powerful Jedi, partly from her heritage as a Skywalker, and mechanical aptitude as well. Sometimes impulsive, she evolved as a character until the time came for her to seize destiny.
Her twin brother Jacen fell to the dark side, taking the name Darth Caedus. Jaina had to face him and upon ending his life, she begged for his forgiveness. She went on to marry Jagged Fel who became the first Emperor of the Fel Empire, a more just version of Palpatine's Empire.
2 Worst: A'Sharad Hett, who became Darth Krayt
The primary villain in Star Wars Legacy was a new Sith Lord named Darth Krayt. His identity was a secret for several issues. Eventually, it was revealed that he was a former Jedi from the Clone Wars era named A'Sharad Hett.
Hett grew up on Tatooine, where his father had lived among the Sandpeople. When he became Darth Krayt, he spent some amount of time in stasis due to the Yuuzhan Vong implants growing into bony plates within and around his body. He was an uninspired villain emerging from an even less inspired Jedi.
1 Best: Mara Jade Skywalker, Luke's Wife
Mara Jade was unique in that she debuted in the Thrawn trilogy and she hated Luke Skywalker for ending the Empire she served. Formerly operating as one of the Emperor's Hands, she quickly found herself drawn to Skywalker. Eventually, they fell in love and married. She dedicated her life to the New Jedi Order.
Mara Jade was a contributing part of the resistance that defeated the Yuuzhan Vong invasion. She trained Jaina Solo. Tragically, she was killed by her nephew Jacen Solo, who had fallen to the reformed Sith. In death, she willed herself not to join with the Force, so her body could give valuable clues to her killer.
