Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
As soon as a kid named Skywalker started running around, Vader knew he had a son, but he did not realize he had a daughter until he found her in Luke's mind. So until Luke realized Leia was his sister, Vader could not have known. Once Luke did know, it was only a matter of time until Vader discovered his other child.
During the iconic opening moments of Star Wars: A New Hope, Darth Vader has a tense confrontation with Princess Leia, an adversary who, unbeknownst to him, is actually his daughter. Despite participating in Leia's interrogation, the Sith Lord doesn't uncover his familial connection with the rebellious royal.
Alderaan's princess knew she had been adopted by Bail and Breha Organa after the Clone Wars, but she had no idea who her parents were. That was until Luke Skywalker told her the truth - that he was the son of Darth Vader, and that she was his sister.
In Star Wars Legends Leia was visited by the force ghost of her father Anakin Skywalker, the man who used to be Darth Vader. It wasn't a pleasant meeting as Leia was unable to forgive him for the things he'd done no matter how hard he begged, and it was the only time she saw him.
Did Vader Sense Leia Was His Daughter in A New Hope? (Legends)
Did Vader know Leia was his daughter?
Darth Vader didn't learn he had a daughter until Return of the Jedi, when he stood before Emperor Palpatine. The Emperor's power probed Luke's mind, attempting to goad him to fall to the dark side, and he discovered Leia's existence. "Sister," the Emperor taunted.
Leia was not using the Force or was currently Force-sensitive during her confrontation with Vader. She began training as a Jedi years later. All these reasons prove my point: Vader didn't know Leia was his daughter, and felt no presence of the Force in her, as she was not currently strong with the Force.
Anakin Skywalker was 22 years old in Revenge of the Sith, a crucial moment when he falls to the dark side and becomes Darth Vader. Darth Vader was 44 years old when he confronted Luke on Bespin in The Empire Strikes Back, attempting to seduce his son to the dark side.
No, Anakin was never made aware that he had children until he is initially confronted with Luke, and then suspects between ANH and ESB that Luke is his son. Obi-Wan comments that "the Emporer knew, as I did, that if Anakin were to have any offspring they would be a threat to him.
He eventually became so desperate to find a way to prevent Padmé from dying that his fear was ultimately the main reason that led to his fall to the dark side. Vader screaming for the loss of Padmé. Even as a Sith Lord, Anakin still loved Padmé very much, but felt great guilt for his actions against her.
During the Imperial Era, a human female nurse served the Galactic Empire on board the Death Star under the supervision of a doctor. They both served the Sith Lord Darth Vader as his personal medical caretakers. The nurse became obsessed and psychotically in love with the Dark Lord of the Sith.
The added risk Darth Vader takes in allowing children to live in a situation where he could have killed them proves that he regrets killing Younglings and will avoid harming any more children for the rest of his days, though intense intimidation is a dark strategy to avoid repeating his Youngling massacre.
Darth Vader acts like he doesn't even know C-3PO or R2D2. They were with him since he was a child. He did everything he could to forget his past. Also, his plating had been replaced many times, and protocol droids all look very similar.
Even though Luke tried his best to protect him, Anakin accepted his fate and expressed his love for his son and daughter, Leia, whom he learned about before dying. While it seemed like Anakin had lived a long life, his choices eventually led to his demise at 45.
In this comic issue, Darth Vader is informed by Boba Fett that the Rebel pilot who destroyed the Death Star is named Luke Skywalker, who Vader immediately recognizes as his son. The scene is repeated in issue 6 of 2015's Darth Vader comics, with Vader vowing, “He will be mine. It will all be mine.”
No. Neither Luke nor Leia found out they were siblings until the third film, Return of the Jedi. Indeed, it wasn't decided that they were siblings until the making of that film (because Lucas no longer wanted to make further sequels about a search for Luke's sister, and decided to wrap everything up with Jedi).
Luke and Leia never sensed that they were twins until Return of the Jedi despite both being sensitive to the Force. Anakin Skywalker's twin children are the original Star Wars trilogy's driving force, having been separated after Padme's death.
Leia and Han had three children, and they named their youngest son Anakin after Anakin Skywalker, Leia's biological father. Since Luke was the twin to spend more time with Obi-Wan in the old canon, it made sense that he, not Leia, was the one to honor Obi-Wan when naming his child.
He terrorized the galaxy at his masters side for over twenty years. Luke however did forgive his father, Anakin Skywalker. He knew he was manipulated by Sidious. That his father was a good person.
It was the fact that Luke was his son that caused turmoil within Vader. It was his love for his son that caused his loyalty to Palpatine and the Dark Side to falter. If Vader didn't know who Luke was he would have been just another force sensitive person to be trained to serve Palpatine like an Inquisitor or be killed.
