The Clone Wars Legacy is a canon multimedia project that revolved around unproduced/unfinished episodes of the television series Star Wars: The Clone Wars. Two arcs were released as story reels (one of which was later completed for Season Seven), and two arcs were adapted for print (the comic mini-series Star Wars: Darth Maul—Son of Dathomir and the novel Dark Disciple).
Although it had not yet been branded as The Clone Wars Legacy, the first story of the series was announced on January 7, 2014 as the comic mini-series Star Wars: Darth Maul—Son of Dathomir. The second story, the novel Dark Disciple, was announced at San Diego Comic-Con on July 25, 2014. StarWars.com officially revealed the brand name The Clone Wars Legacy on September 25, 2014, at which time the four-episode "Crystal Crisis on Utapau" arc was released online in the form of animated story reels.
On April 9, 2015, StarWars.com announced that another unfinished, four-episode story arc, "Bad Batch," would be screened in story-reel form at Celebration Anaheim. The arc's writer, Brent Friedman, previously released a good amount of information on the episodes via his Twitter account.
Darth Maul—Son of Dathomir is a comic miniseries adapting a four-part story arc that was produced for the series' seventh season. The episode scripts were adapted by Jeremy Barlow and published by Dark Horse Comics in 2014, the final year of the publisher's Star Wars license.
The comic was based on the following episodes written by Aïda Mashaka Croal and Matt Michnovetz:
"Crystal Crisis on Utapau" is a four-part story arc of unfinished episodes, released in story reel form on StarWars.com and later on the Blu-ray release of Star Wars: The Clone Wars – The Lost Missions.
The "Bad Batch" arc was originally intended to be the premiere for a seventh season. The episodes were first screened in story reel form at Celebration Anaheim and were released on StarWars.com shortly thereafter. On April 14, 2019, It was revealed at Celebration Chicago that a finalized version of the Bad Batch arc would be part of the Star Wars: The Clone Wars revival season. Starting on February 21 2020, these episodes were debuted weekly on Disney+.
Dark Disciple is a novel written by Christie Golden that stars Asajj Ventress and Quinlan Vos. The novel is based on an eight-part story arc that was scripted but not fully produced.
In March 2016, Lucasfilm Story Group's Pablo Hidalgo stated that there were 13 story arcs left after the release of the sixth season. First-draft scripts had been written for seasons 7 and 8 prior to the series' cancellation. Brent Friedman confirmed via Twitter that each arc was four episodes long. Hidalgo also confirmed that production season 5 had 25 episodes while production seasons 6 and 7 had 24 episodes each. According to Hidalgo himself, the unfinished episodes from which The Clone Wars Legacy consists were the last huge expansion of the Star Wars universe that came directly from George Lucas.
This four-episode arc was written by Matt Michnovetz, and had production codes 5.22–5.25. In this arc, Boba Fett and Cad Bane were going to team up for a "rescue mission" on Tatooine where Tusken Raiders had kidnapped a child. It would emphasize Boba's and Cad's relation to one another as Cad had known Jango. The story would be heavily influenced by the film The Searchers, which George Lucas likes. Aurra Sing, Seripas, C-21 Highsinger, Embo, Latts Razzi, and Bossk were also going to be in the story according to concept art. Cad Bane got new clothes, was accompanied by Todo 360, and had a new ship called the Justifier. Dewbacks and a Tusken Shaman would have appeared, as well as new elements such as the building Minions Wreck and Wares the droid Ruckle, and a Toong named Lancek Trevoras.
In a clip revealed during the Animated Origins and Unexpected Fates panel at Celebration Orlando in 2017, Cad Bane and other bounty hunters had ended an insurrection by Fett, also involving Seripas, a new character named Stim, and the unseen Sugi. To finish it, they engaged in a stand-off duel; in which Fett got his helmet dented. Daniel Logan, Boba Fett's voice actor, reported in the London Comic Con 2018 that he actually recorded lines as Fett for seven episodes, including the one of the Fett/Bane duel.
A four-episode arc with production codes 6.05–6.08 was to follow Ahsoka Tano after her decision to leave the Jedi Order. This arc was to show some of her first adventures in the underworld where she met a scoundrel named Nyx Okami, whom she developed a close relationship with. Ahsoka's character was challenged when she got involved with the underworld and the Pyke Syndicate, but had to resist her Jedi teachings for her own safety. On April 14, 2019, It was revealed at Celebration Chicago that Ahsoka's Walkabout will be adapted as part of the Star Wars: The Clone Wars revival season, although it was revealed that two new characters, Trace and Rafa Martez, would be taking Nyx's place in the story arc. Starting on March 20 2020, these episodes were released weekly on Disney+.
Tarfful speaks to the trees
A four-episode arc written by Matt Michnovetz with production codes 6.17–6.20 starred Yoda and the Bad Batch on Kashyyyk. At the "Untold Clone Wars" panel at Celebration Anaheim, Dave Filoni talked about the plot of the arc. He revealed the the characters would ride on giant ape lizards that were holy to the Wookiees. In one scene, Tarfful would ask the tree spirits for permission to go into battle against the enemy, which was a number of Trandoshans led by Babwa Venomor, and the Separatist Alliance. To get the enemy out of some of their cities, they would have to burn some of the trees. The clones had no problem with it, but it was upsetting to the Wookiees. A part of the arc would be about the clones and the Wookiees finding a common ground to fight the Separatists. Some of Yoda's troopers would have his head silhouette on their helmets, and Echo would now be part of the Bad Batch squad. A story-reel clip was shown at the panel, which showed the Bad Batch and other Wookiees—including Major Clausito—battling netcasters, creatures whose design was based off the kinrath from the Star Wars: Knights of the Old Republic game. Only parts of the four episodes of the arc were made into animatics before the series' cancellation. Dave Filoni revealed at Celebration Europe II that Yoda would be in the arc to give credit to the line "Good relations with the Wookiees I have" from Revenge of the Sith. Matt Michnovetz revealed that Chewbacca would have played a huge role, and that the arc would have contained some references to The Star Wars Holiday Special.
In the Star Wars: The Bad Batch episode "Tribe," as the Clone Force 99 return to Kashyyyk, Wrecker mentions that they had been on Kashyyyk before, which StarWars.com confirmed to be a reference to the events of the unproduced Kashyyyk arc of The Clone Wars, as Michnovetz wrote both episodes, counting with several similar elements such as the Netcasters, Mylayas and Trandoshans.
Brent Friedman wrote the script for a four-episode arc starring Rex and R2. This story showed the ground forces of the Clone Army getting into an argument with the pilots, and their astromechs, including R2-D2. This arc featured Rex and R2, where Rex flew a starfighter with R2 as his copilot. They would crash and be stranded together on one of the moons of Ryloth, where most of the episodes would take place. Rex and R2 reprogrammed a B2-series super battle droid that they would grow attached to, and at some point Rex was injured. Friedman commented that the arc started out light and fun but then went to "some very unexpected and dark places."
This story would have involved the Yuuzhan Vong in a very minimal way. A scout ship was trying to assess the strength of the Republic and what Jedi were. Pablo Hidalgo commented that it was a creepy story and would have been like a The X-Files episode with an alien-abduction event. To better align with George Lucas' description of the Force, the Vong did not have any Force immunity in this story. Pablo said the story never got into the origins of the Vong, but that they probably were from another galaxy.
Ahsoka being shocked by Darth Sidious' Force Lightning
This story would be about what lay beneath the Jedi Temple, similar to how churches were often built on the previous religious center. Different Force-user temples, and maybe even a Sith shrine, would be beneath. There would be giant skeleton Kaiju down there. Ahsoka discovers a threat in the underworld of Coruscant and makes her way back to the Jedi Order to warn them. She, Obi-Wan Kenobi and Anakin Skywalker set out to rescue Master Yoda from the Sith shrine. The arc would also have featured Darth Sidious trying to break into the Holocron Vault of the Jedi Temple, but Ahsoka would hinder his progress.
This story had productions codes 7.17–7.20 and would have starred Padmé Amidala working against Chancellor Palpatine's prolonged stay in office. In episode 7.19 Padmé and Anakin Skywalker returned to Mon Cala to meet with King Lee-Char once again. While there, they found out that the leader of the Quarren, Nossor Ri, had been murdered, and Tikkes had been appointed provisional leader in his place. Padmé hoped to gain support from the Quarren to remove Palpatine from office. The Quarren Senator Tundra Dowmeia explained to Padmé that their government was gridlocked and unable to function. They would meet with Tikkes, who expressed frustrations with Palpatine.
In the comic book miniseries Star Wars: Allegiance, it was confirmed Ri survived the Clone Wars in canon. Instead of dying during that conflict, Ri met his end by sacrificing himself in the name of Mon Cala during the First Order-Resistance War in 34 ABY.
Dave Filoni's sketch of Captain Rex, Ahsoka Tano, and Bo-Katan Kryze during the siege of Mandalore
This arc had production codes 7.21–7.24 and was to be the final arc of the series. It would have shown Ahsoka Tano teaming up with Obi-Wan Kenobi and Anakin Skywalker to respond to a call of Bo-Katan Kryze alerting the Jedi of Darth Maul's return with the remains of the Shadow Collective. However, during the battle, General Grievous causes a surprise attack and kidnaps Supreme Chancellor Palpatine, so that while Anakin and Obi-Wan go to rescue Palpatine, Ahsoka and Captain Rex remain in command of the clones, who paint their armor with Tano's facial markings. Part of this arc was adapted into the prologue of the novel Ahsoka by E. K. Johnston, and it was first mentioned in the Star Wars Rebels episode "The Lost Commanders." Starting on April 17, 2020, these episodes were released weekly, with the exception of "Victory and Death" which premiered on May 4, on Disney+.
Back in 2010, in the DVD commentary track of the second season, Dave Filoni and Danny Keller mused about the possibility to bring back the Zillo Beast in the seventh season. Dave Filoni also had "plans" to feature Barriss Offee following her deception in the fifth season finale "The Wrong Jedi," an episode whose original ending had Offee killing herself but was changed due to Filoni's plans.
Aurra Sing was meant to be featured in several unfinished episodes for the sixth season, including one in which she would have been killed and one in which Jaime King's husband Kyle Newman was going to have a role. Newman's role consisted of a member of the Toong species.
The Bounty Hunter Arc would have concluded with Cad Bane's death at the hands of Boba Fett in a duel. Since the release of the Star Wars: The Bad Batch episode "Reunion," Cad Bane's survival into the Imperial Era was confirmed, though dialogue from the subsequent Disney+ live-action series The Book of Boba Fett heavily hints at Bane's mentorship of Boba Fett and their duel to still have happened.
The story of "Return to the Jedi Temple" is not a part of Star Wars canon given that the 2014 novel Tarkin, written by James Luceno, establishes that Darth Vader was unaware about the Sith shrine under the Jedi Temple. In the unproduced story, Anakin Skywalker accompanied Obi-Wan Kenobi and Ahsoka Tano to rescue Yoda from the shrine.
The "Return to Mon Cala" story cannot be considered canonical as well, because Nossor Ri would have been murdered during the arc. The fourth issue of the Star Wars: Allegiance 2019 comic book series establishes that Ri survived until at least the Battle of Crait.
