Remember that this is the first (and only) time Vader saw C3PO after RoTS. Threepio was getting pushed into an escape pod by R2D2 by the time Vader entered their ship in ANH. Though he was chased throughout the original series, this was the only time Vader actually saw Threepio, again.
Yes, he did. In the comic Thank the Maker, Darth Vader comes into possession briefly of 3PO's disassembled head while on Cloud City. Why didn't anyone like Obi Wan, the Lars family, or Darth Vader recognize C-3PO or R2-D2?
The base assumption of why Obi-Wan doesn't remember R2-D2 -- in light of the prequels -- is that Obi-Wan is feigning ignorance in A New Hope to downplay the importance of the droid's arrival.
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
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.
How Darth Vader Met and Remembered C-3PO on Cloud City
Why did Obi-Wan not remember R2D2?
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.
C-3PO, his robot companion, could speak 6-million languages including excellent English with a hint of a British accent and all R2-D2 could muster were beeps and whistles. Clearly the technology was there to let him speak, but whoever designed him intentionally decided to stick with the beeps and whistles.
However, R2-D2's memory is not wiped; as a result, R2-D2 is the only surviving character at the end of the saga who knows the entire story of the Skywalker family. Both R2-D2 and C-3PO end up in the possession of Captain Raymus Antilles (Rohan Nichol) onboard the Tantive IV.
She senses Anakin when she reaches out to the pilot — and Vader realizes that Ahsoka, his former Padawan, lives on. In Season 2, Episode 18, “Shroud of Darkness,” Ahsoka's guilt manifests as a vision of Anakin, who's angry with her for leaving him all those years ago.
Vader mocked Luke for his lack of training in lightsaber combat, and he easily pulled the lightsaber out of Luke's grasp through the Force. However, before Vader could strike the unarmed Luke down, he suddenly recognized Luke's lightsaber as his own former weapon.
C-3PO met Anakin outside the Lars homestead; though they both had changed -- Threepio now had a gray outer casing, and Anakin had grown up -- they recognized each other.
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.
Thanks to healing techniques she learned from ancient Jedi texts, Rey mended Anakin's Kyber crystal and repaired the hilt, restoring it to working condition. The Kyber crystal and (and subsequently, the blade) remained blue, however.
Obi-Wan Kenobi's third lightsaber was his new weapon that he created during the Clone Wars upon his promotion to Jedi Master and wielded until his death after his rematch with Darth Vader on the Death Star.
He gave it to Luke Skywalker, who lost it when Darth Vader struck off his son's hand in Cloud City. The lightsaber then became part of Maz Kanata's collection of Jedi curios, where it called to the scavenger Rey.
In my opinion, I think it's hard to compare Anakin's relationship with Padmé to his relationship with Ahsoka because the nature of the relationships are different: Anakin romantically loved Padmé, meanwhile he loved Ahsoka unconditionally like a sister/daughter.
They grew acquainted with each other, considering each other as friends and met through their affiliation with Anakin Skywalker. At some point, Ahsoka suspected that Anakin and Padmé were in a secret relationship but chose not to say anything because it was none of her business.
If that is the case, Darth Vader bled the kyber crystals of the lightsabers he had only recently returned to Ahsoka, turning them to the dark side. Even more disturbingly, when Vader fought Ahsoka years later he used that same dual phase lightsaber against her - a ddark symmetry the Sith Lord would no doubt appreciate.
A smart, spunky droid who would serve a multitude of masters over his lifetime, R2-D2 was never given a full memory wipe nor did he ever receive new programming, with these factors resulting in an adventurous and independent attitude.
R2-D2, sometimes spelled Artoo-Detoo and often referred to as Artoo, was an R2-series astromech droid manufactured by Industrial Automaton prior to 32 BBY, who would participate in major galactic events for nearly two centuries alongside the Skywalker family.
