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.
In The Phantom Menace, set 32 years before A New Hope, R2-D2 is portrayed as belonging to the Naboo defense forces, one of three astromech droids deployed for repair duty onboard Queen Padmé Amidala's (Natalie Portman) starship as it attempts to get past the Trade Federation blockade.
As such, R2D2 appears to be the state property of Naboo. Queen Amidala as the head of state exercised her control over R2D2. The Droid continued his service to Amidala while she was a Senator. C3PO was built by Anakin Skywalker.
After C-3PO and R2-D2 landed on Tatooine, Jawas picked up the two droids, fitting them with restraining bolts. The Jawas sold the robots to Owen and Beru Lars and their nephew Luke Skywalker, a seemingly minor event that would change the fate of trillions in the galaxy.
The first was Queen Amidala, who passed it to Anakin, who after being left for dead on Mustafar lost R2 who was recovered by General Kenobi who handed R2 over to Bail Organa, who sent him with his adoptive daughter Princess Leia, who ejected him to Tatooine, where he was recovered by some Jawas and sold to Owen Lars, ...
LOS ANGELES — An R2-D2 unit that was used in several “Star Wars” films has sold at auction for nearly $3 million.
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.
Akial was a Jawa male who was a member of the Jedi Order during the years of the Galactic Republic. He trained at the Almas Academy, a Jedi academy that was located on the planet Almas, where he specialized as a Jedi Consular.
Yoda recognized R2-D2 during The Empire Strikes Back.
These devolved humanoids use yellow/orange gemstones to protect their eyes from the harsh suns on Tatooine, which explains their glowing eyes.
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 was later able to restore his companion during the Battle of Geonosis. After the battle, R2-D2 and C-3PO were the sole witnesses to the marriage of Anakin Skywalker and Padmé Amidala in Lake Country. After this Padmé gave ownership of R2 to Anakin while she kept 3PO.
During this week's edition of The Star Wars Show web series, Lucasfilm revealed the first look and details of the droid C2-B5. He (or, rather, it) is essentially a black-painted R2-D2 because, as we learn in the video shown below, both are part of the astromech droid family.
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.
To keep audiences thinking that R2-D2 was moving all by himself, Kenny Baker's legs were hidden using pipes that led to the droid's feet. This allowed him to control the astromech's movement when he was hidden inside.
In an interview with Wired, director J.J. Abrams refers to BB-8 as a “he,” while Neal Scanlan, the head of the creature shop at Lucasfilm, seems a bit more confused in his talk with EW: I'm still not sure, dare I say, whether BB-8 is male or female. BB-8 was female in our eyes.
Perhaps, Darth Vader just figures that this is another protocol droid and not C-3PO. Obviously, C-3PO does not recognize Vader because his memory was wiped at the end of Revenge of the Sith.
His memory was wiped at the end of Revenge of the Sith. A blabbermouth like him can't be trusted with sensitive information.
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.
Arguably, some of the rarest types of Jedi were the so-called Iron Knights. These are members of the Shards species - crystals with a brain of their own.
During the reign of the Galactic Empire, the human male Haja Estree resided on the planet Daiyu, working as a con artist. In his scam, he posed as one of the Jedi, Force-sensitive peace-keepers who were hunted by the Empire after their Jedi Order was destroyed in 19 BBY.
The first Dark Jedi was believed to be Xendor, who was the first member of the Jedi Order to fall. Other forerunners included Ajunta Pall and others who, after the Hundred-Year Darkness, were exiled from Galactic Republic space and became the ancient progenitors of the Sith Lords.
Of course, the Father almost immediately wiped Anakin's memory, because he couldn't very well achieve balance knowing what he knew of his future. That's very interesting, though. It means that the Father knew that Anakin will become Vader, will destroy the Jedi, will literally annihilate whole worlds….
In honor of Jyn Erso and her crew's sacrifice at Scarif, Luke Skywalker ordered for the specific "Rogue One" designation that they used to be retired. This led to Luke flying instead as Rogue Leader. He used the callsign in the defense of Hoth's Echo Base when it was besieged by the Empire.
C-3PO returns in Star Wars: Episode I – The Phantom Menace, the first chapter of the Star Wars prequel trilogy, where it was revealed that nine-year-old slave Anakin Skywalker (Jake Lloyd) built him out of spare parts.
