The relationships of Darth Vader.
- Main article: Emperor Palpatine
The Emperor was the man who turned the former Anakin Skywalker into a Sith Lord. He owned Darth Vader like a slave, but together the two were the most feared beings in the galaxy. For many years before his fall to the dark side, Anakin had considered Palpatine to be a good friend and even another mentor, not realizing Palpatine was swaying him to his side, turning him against his fellow Jedi. Palpatine preyed on Anakin's doubts, fears, his ego, and his desperation to save his beloved Padme from dying in childbirth, hinting of a secret to save others from death. When Anakin finally fell and swore himself to the Sith, he had realized that he'd been tricked, but could never go back to the Jedi.
Palpatine never really considered Vader his apprentice but merely his pawn and enforcer, and a broken one after Vader's injuries. Both Sith Lords hated each other, but were forced to tolerate the other to secure their grip on the galaxy with the Empire as their tool.

The Grand Inquisitor
- Main article: The Grand Inquisitor
The Grand Inquisitor served as Vader's primary agent and Dark side adept, obeying his every command without question. At the bidding of his master, Vader ordered the Inquisitor to hunt down and vanquish the new found Ghost crew when Kanan Jarrus, their de facto leader, is discovered a Jedi.
When he is defeated by Kanan over Mustafar, the Inquisitor warns the Jedi he has no idea what he has unleashed, and that there are things worse than death, before he allows himself to fall to his own. His taking his own life and final words imply the Grand Inquisitor feared whatever punishment Vader would have for him; he was obviously more afraid of his master's wrath than death itself.
The Fifth Brother
- Main article: Fifth Brother
The Fifth Brother served as one of Vader's Dark side adepts, obeying his every command without question. At the bidding of his master, Vader ordered the Brother to partner with the Seventh Sister and continue the Grand Inquisitor's work to hunt down and vanquish the Ghost crew and Phoenix Squadron they have allied themselves with since Kanan Jarrus is a Jedi and when Ahsoka Tano, Vader's old Padawan, is discovered among them as the Phoenix de facto leader.
The Seventh Sister
- Main article: Seventh Sister
The Seventh Sister served as one of Vader's Dark side adepts, obeying his every command without question. At the bidding of her master, Vader ordered the Sister to partner with the Fifth Brother and continue the Grand Inquisitor's work to hunt down and vanquish the Ghost crew and the Phoenix Squadron they have allied themselves with since Kanan Jarrus is a Jedi and when Ahsoka Tano, Vader's old Padawan, is discovered among them as the Phoenix de facto leader.
- Main article: Kallus
Like The Inquisitor, Kallus and Vader work together to destroy the rebellion. Kallus is always in Vader's office, awaiting orders. Like The Inquisitor, Kallus does every order to try to capture or destroy the rebels, but unlike the Inquisitor and most imperials, he didn't seem to be afraid of Vader. Kallus has shown to be very obedient to Vader's orders and displayed no reservations on the sheer cruelty of the Dark Lord's plans to draw out and defeat the rebels, such as murdering Minister Tua, framing her death on the rebels and having Tarkintown burned and it's citizens imprisoned.
The Eighth Brother
- Main article: Eighth Brother
The Eighth Brother served as one of Vader's Dark side adepts, obeying his every command without question. At the bidding of his master, Vader ordered the Brother to hunt down Emperor Palpatine's former Sith apprentice, Maul.
- Main article: Obi-Wan Kenobi
Obi-Wan first met the nearly-10-years-old Anakin Skywalker on Tatooine before the Battle of Naboo. Skeptical of his Master Qui-Gon Jinn's insistence that the boy was the Chosen One at first, Obi-Wan was shocked at Anakin's extremely-high Midi-Chlorian count and would later take him on as his Padawan learner at Qui-Gon's dying request. Their relationship as Master and Padawan was rocky, but the two soon grew to see each other as brothers after Anakin became a Jedi Knight at the explosive start of the Clone Wars. They fought side-by-side throughout it, and Obi-Wan became something of a second mentor for Anakin's Padawan, Ahsoka Tano. When Anakin was turned to the dark side by Emperor Palpatine, becoming Darth Vader and killing hundreds of Jedi and younglings, Obi-Wan was heartbroken at what Anakin had caused, but reluctantly accepted Yoda's mission for him to kill his fallen pupil while Yoda confronted Palpatine. After a perilous duel on Mustafar between former Master and Apprentice, Obi-Wan defeated and dismembered Anakin, who then screamed eternal hatred for Kenobi before he was engulfed by flames. Despite Vader's obvious pain, Obi-Wan refused to kill the defenceless Sith Lord and remorsefully left Vader to die. He later delivered Anakin's son Luke to his uncle and aunt on Tatooine, where he remained in exile.
Since then, Vader has sworn to hunt Kenobi down and make him pay for his injuries.
- Main article: Ahsoka Tano
- “Then you will die!”
- ―Vader breaks the bond he and his student once shared.
When Ahsoka and Anakin first met, their relationship was rocky, due to Ahsoka's "snippy" attitude and Anakin having not wanted a Padawan to begin with. They eventually developed a close bond with each other, similar to a child and parent or even a big brother and little sister. When Ahsoka chose to leave the Order, Anakin was very sad, conflicted and felt personally responsible. Ahsoka was grateful to Anakin for having believed in her and stood by her through it all, but felt she simply could not stay, that she had to work through this matter without the Jedi Order and without him, stating she knew how he understood the choice of leaving the Order.
Later on in the war, Ahsoka saw Anakin again just before he left to save Chancellor Palpatine.
That would be the last time Ahsoka would see her former teacher as the man he was.
During Vader's attack on the Rebel Fleet, both Ahsoka and Vader became aware of each others' existence and Ahsoka was left suspicious of who Vader was. Later, when Vader informed the Emperor of Ahsoka's survival, the former ordered him to personally hunt her down and use her to find any surviving Jedi.
While meditating in the Lothal Jedi Temple, Ahsoka had an illusion of Anakin's disappointment in her leaving and then transformed into Vader. Ahsoka then lashed out, only to find nothing there. Despite finding out the truth, Ahsoka still refused to believe Anakin was Vader.
Upon their long-awaited reunion on Malachor, Vader offered her mercy in exchange for the location of any remaining Jedi, which Ahsoka refused, and voiced her doubts of who she thought was behind that mask, to which Vader coldly responded that he had destroyed Anakin Skywalker, spurring a duel between them. When Vader finally revealed his true identity to Ahsoka, even when she offered him compassion, he cruelly declared his intent to kill her, and any trace of the bond he and his former student once shared died completely. It is unknown who ultimately came out on top in their battle, as Vader survived while Ahsoka's fate was left ambiguous.
- Main article: Rex
During the Clone Wars, Rex and Anakin led the 501st and fought together side by side against the Separatists. Rex was very respectful to his general and listened to what Skywalker ordered. However, it is unknown if Rex was aware that his General had turned into a Sith Lord, as Rex was with Ahsoka on Mandalore when the 501st marched on the Jedi Temple during Order 66.
- Main article: R2-D2
Before Anakin Skywalker became Darth Vader, R2 was Anakin's astromech and a good friend. Anakin and R2 first met when Anakin was 10 years old on Tatooine. During the Clone Wars, R2 went missing and Anakin went to great lengths to get him back.
R2 was deeply upset when Anakin turned to the Dark Side and never revealed the friendship they once shared.
- Main article: C-3PO
Anakin built C-3PO when he was a little kid. During the Clone Wars Anakin became annoyed of C-3PO's constant complaining.
After Order 66 was executed, and Anakin becoming Darth Vader, C-3PO's mind was wiped so his information wouldn't get into the Empire's hands, meaning that C-3PO's memories of Anakin were erased as well.
- Main article: Hondo Ohnaka
Hondo held Anakin, along with Obi-Wan and Dooku hostage. But after they freed themselves, they left Hondo's base with no intention for revenge. Which Hondo respected. Three years later after the Separatist invaded Onderon Anakin knew Hondo had the right weaponry to stop them.
- Main article: Kanan Jarrus
When Kanan was about to fight with Vader, he and Ezra sensed a cold feeling when Vader arrived or is nearby. Kanan was shocked to find out that Vader is not a Inquisitor but he is a Sith Lord, Kanan was injured in the duel. He later described to Ahsoka the feelings of anger and hate he felt from Vader's presence. It is currently unknown if Kanan knew Darth Vader when he was still Anakin Skywalker during the Clone Wars.
- Main article: Ezra Bridger
- “Your master has deceived you, into believing you can become a Jedi.”
- ―Darth Vader talking about Ezra's potential.
Darth Vader contacted The Grand Inquisitor about a new threat rising against the Emperor; The children of the force. It is possible that Ezra was one of those threats that Vader was talking about. During a mission to rescue Maketh Tua, Ezra started to feel Vader's presence on Lothal; Resulting in him becoming extremely cold. Later when the Rebels were trying to leave a aboard an Imperial Shuttle, Ezra again felt Vader's presence through the Force; who was right behind them. Ezra and Kanan then engaged Vader with their lightsabers but it quickly became apparent that neither of them were match for the Sith Lord. During the battle Vader had Ezra pinned, about to cut his throat with his own lightsaber, until Kanan distracted Vader saving Ezra's life. Ezra narrowly escaped with the others. Later, during Vader's attack on the Rebel fleet, Ezra once again felt Vader's presence, and started to feel the cold. Ezra once again narrowly escaped Vader's grasp.
Ezra admired Anakin Skywalker's abilities with a lightsaber, and even watched his training recordings for his own training.
When they met again on Malachor, Vader was curious as to how Ezra (a mere Jedi Padawan) could have unlocked the secrets of the Sith Temple, but ultimately decided it was irrelevant, as he intended to claim the temple in the name of his master. When Ezra claimed he was not afraid of the Sith Lord, Vader simply retorted "then [Ezra would] die braver than most" and easily destroyed the padawan's lightsaber, and mocked him by saying perhaps he was wrong that Ezra would indeed die without fear, and would have killed him had not Ahsoka arrived. When Ahsoka declared there were no more Jedi because Vader and his inquisitors had hunted them down, Vader threatened to interrogate Ezra for the information he desired.
- Main article: Sabine Wren
Vader and Sabine first met after the mission to save Maketh Tua went south. After they realized that they were outmatched they tried to flee on board a Imperial shuttle. When Vader was following Kanan and Ezra, she tried to buy time by firing at him, but he deflected it back at her with ease; this confrontation was the limit of their interaction.
