After Anakin falls to the dark side of the Force and becomes Darth Vader, he takes R2-D2 with him when he goes to assassinate the Separatist council, but he tells him to stay with the ship.
Summary. Anakin's fall to the dark side had a heartbreaking effect on R2-D2, who felt abandoned and ignored by his former master. Star Wars droids like R2-D2 rarely receive emotional depth, making R2's words about Anakin's betrayal even more tragic.
To answer the original question, I'm pretty sure that R2 never knew that Anakin became Vader. He wasn't there when Anakin was named Vader, he didn't know what happened on Mustafar. All he knew is that Anakin told R2 to stay with the ship, and that was the last time R2 saw Anakin.
Vader ultimately redeems himself by saving his son, Luke Skywalker, and killing Palpatine, sacrificing his own life in the process. He is also the secret husband of Padmé Amidala, the biological father of Princess Leia, and the grandfather of Kylo Ren (Ben Solo).
secondly, in Legends, R2 was given programming that actually restricted him. from sharing any information with Luke or Leia. about their parents or relation to one another. this was all part of the plan. to conceal this information from the twins.
Two Royal Guards that Didn't Recognize Darth Vader(Canon) - Star Wars Comics Explained
Does R2 still remember Anakin?
Star Wars Theory: R2-D2 Didn't Know Anakin Skywalker Became Darth Vader. R2-D2 served Queen Amidala and later Anakin Skywalker, accompanied by C-3PO. Unlike the golden protocol droid, R2-D2 never had a full memory wipe, so he was well aware of all events that happened around him.
in the Dark Horse comic series star Wars Tales, which is now part of legends, it's revealed that Darth Vader did recognize C. 3PO on Cloud City. when 3PO was shot by Stormtroopers, his parts were brought before Vader. because the Imperials thought he could hold valuable.
Their battle was interrupted when Leia used the last of her strength to reach her son in the Force. While Kylo was distracted, Rey ran him through with his own lightsaber, leaving him mortally wounded.
The dark side of the Force is a pathway to many abilities some consider to be unnatural, and Sheev Palpatine is the most infamous follower of its doctrines. Scheming, powerful, and evil to the core, Darth Sidious restored the Sith and destroyed the Jedi Order.
Age, his suit and his de-limbing lower his strength, but obviously his pain, anger and hate connect him to the dark side and make him more powerful. It's hard to quantify his power at the end without those dark side variables.
However, one theory argues that Obi-Wan did recognize R2-D2, but he chose to pretend not to in order to avoid telling Luke the full truth. This would explain certain signs of familiarity between the Jedi and the droid and fit Obi-Wan's pattern of subtly lying to Luke.
You saw how Luke's attitude completely changed when he realised that was actually Yoda and so did Yoda's behaviour. As for the r2 thing, is incredibly likely he just suspected R2 had had his memory wiped several times since they last saw each other.
Do R2D2 and C3PO know that Darth Vader is Anakin? Threepio had his memory wiped at the end of Revenge of the Sith. He doesn't even know Anakin was Anakin. In universe answer: Vader didn't share scenes with R2 or 3PO.
3PO ended up in a cave (only his upper body was still intact), and he became a local legend known as "The Storyteller". Two young kids called Otalp and Remoh escaped their oppressors and visited 3PO, who told them the story of Luke Skywalker. Then the oppressive alien species showed up, and shot 3PO to death.
R2-D2 was part of the repair crew for the Naboo Royal Starship. He technically is owned by Naboo's elected royalty until Padme took him along for her senator duties. By the Clone Wars, Padme gave him to Anakin as she felt a droid like R2 was far more useful to aid Anakin.
After 30 years, this is followed by the sequel trilogy, which is similarly short, covering only around a year from Star Wars: The Force Awakens to Star Wars: The Rise of Skywalker, during which time R2 would be about 66 to 67 years old.
Shmi informs Qui-Gon that Anakin has no father, leading Qui-Gon to suggest that Anakin is a product of midi-chlorians (Force-imparting microorganisms). As the film progresses, Anakin leaves Tatooine to begin his Jedi training.
Rey and Kylo's fight comes late in the third act, after Kylo had murdered Han Solo and been shot by a vengeful Chewbacca. That combination meant Kylo was physically weakened and emotionally compromised when he dueled Rey, meaning he was far from full strength.
One aspect of the Star Wars sequel trilogy that many fans couldn't get behind was the fact that Luke Skywalker, the man chosen by destiny to becomes the greatest Jedi who ever lived, tried to kill his nephew and padawan Ben Solo aka Kylo Ren just because he sensed Dark Side energy within him.
Force projecting himself so far across the galaxy required every ounce of his energy and willpower. While he successfully achieved this feat, the energy and mental stress required to make it happen drained everything from him and is what ultimately killed him.
However, while Yoda acts as though he had never met R2-D2 before, the Star Wars prequel trilogy, released decades later, revealed that Yoda was already well acquainted with the famous astromech droid.
Darth Vader only learned he had a daughter in Return of the Jedi - but there's no evidence he realized she was Leia before his death and redemption. Darth Vader may have never known Princess Leia was his daughter in Star Wars and never cultivated a relationship with her, even when he was a Force ghost.
Darth Vader can not use force lighting, because of his severed arms. Robotic hands can't summon the force lighting. However Darth Vader can still use other forms of the force, such as force choke.
