Shortly later , C - 3PO and Ackbar are approached by an Multi - Troop Transport carrying several B1 battle droid s , who have been reprogrammed as garbage collectors . C - 3PO asks whether the droids have seen R2 - D2 but they deny . While sitting nearby on a fallen statue of the Emperor , the two travelers reminisce the old days . While Ackbar talks about how he first bought the Delta - 7B Aethersprite - class light interceptor " Daisy Mae " from a dealer , Threepio convinces him to let him continue the story about his and R2 - D2 ' s involvement in the Clone Wars . C - 3PO begins with the story of how R2 - D2 thwarted General Grievous and Count Dooku ' s plans to obtain the Galactic Republic ' s battle plans on Coruscant . Darth Sidious passes the secret plans to Grievous , who is shortly later ambushed by Obi - Wan Kenobi , and several Clone trooper s . Grievous ' ship is destroyed but he manages to commandeer Senator Bail Organa ' s ship . C - 3PO , who was preparing food in the ship ' s galley , finds himself an unwilling passenger .

While 3PO flies the ship , Grievous engages Skywalker in a lightsaber duel . The ship narrowly avoids a skyscraper , causing Anakin to fall off the ship . Anakin lands on Kenobi ' s airspeeder while Grievous takes the opportunity to flee to Geonosis with the stolen plans and C - 3PO . Grievous submits the plans to Count Dooku and the Separatist Council including Poggle the Lesser . R2 - D2 then sneaks into the Separatist Council chambers and overpowers a black astromech droid . He then passes himself off as the black astromech droid and discreetly makes contact with Threepio . Meanwhile , Dooku and Grievous gloat that the battle plans will lead them to victory over the Republic . Back at the Jedi Council , Master Mace Windu reprimands Skywalker for his recklessness in jumping out of windows while Yoda advises him to think first . R2 - D2 then manages to broadcast a recording of Dooku and Grievous with the secret battle plans . With the Republic ' s safety at stake , the Jedi Council and Anakin travel to Geonosis , ( and in a comedic fashion , everyone in the room jump out through the window , including Yoda ) . At the Separatist Council chambers , Dooku screens a recording of the stolen battle plans . However , R2 has substituted the real disc for another one showing a video of Ewok s dancing and singing to the Yub Nub song . The Jedi then enter the Separatist Council chambers and fight Dooku and Grievous . 3PO , who is serving cocktail weenies , is caught up in the fighting and knocked to the ground . R2 tries to flee with the plans but is corned by Grievous and several B2 super battle droid s . However , the astromech droid activates his booster rockets and flees into the droid foundries . In the process , R2 gets stuck in the gears , causing the factory to overheat and triggering a chain reaction that destroys the Separatist factories and headquarters . R2 - D2 and C - 3PO escape and bring the plans back into the hands of the Republic . Republic LAAT gunships and ARC - 170 starfighters also arrive on Geonosis . 3PO praises R2 for his actions before hitting him on the dome , telling him to " " Never " do that again ! " Fall of the Republic . Going back to the present , 3PO recalls that he was cross with R2 for putting them into danger and wishes to swot him on the head . However , he still misses his friend despite his annoying traits . They then find Ackbar ' s stolen ship " Daisy Mae " under a pile of paper . 3PO deduces that the mysterious kidnapper has ditched the stolen ship before boarding a shuttle in Coruscant ' s spaceport . While Ackbar tends to his stolen ship , 3PO asks a gatekeeper droid if he has seen R2 . Though the droid is unwilling to help , a sympathetic Ithorian male expresses interest in hearing more about R2 ' s exploits during the Clone Wars . C - 3PO goes back to Count Dooku and General Grievous ' plot to kidnap Supreme Chancellor Palpatine during the last days of the Clone Wars . 3PO witnesses Grievous ' fake kidnapping of the Chancellor in his office and their escape in a " Scimitar " ship . Meanwhile , Anakin is walking with his secret wife Senator Padmé Amidala , who is pregnant , and R2 who congratulates them with a fanfare . Skywalker confides his unhappiness with Kenobi and the Jedi for not seeing his " awesomeness " before going on to discuss the name of Padmé ' s unborn child . Padmé settles on Leia for a girl and Kitster , Embo , Wicket , Jubnuk and IG - 88 before settling on Luke . At that point , the three witness a kidnapped Palpatine blowing the horn from Grievous ' ship . Anakin and Obi - Wan pursue Grievous in their Eta - 2 starfighters and avoid several Buzz - droid s . On the Separatist flagship " Invisible Hand " , Dooku discusses Palpatine ' s " brilliant plant " to lure the Jedi into a trap while simultaneously revealing the full strength of the Sith Order . Dooku thinks that he and his master Darth Sidious will be able to defeat the Jedi together . However , Palpatine betrays Dooku and exhorts Anakin to defeat the Separatist leader . During the fighting , Dooku and Grievous are sucked out the window of the Wizard ' s Tower into space . ( Grievous is able to survive in the vacuum of space due to his cybernetics , swearing that they haven ' t seen the last of him ; Dooku , however , presumably perishes , saying , " You " have " seen the last of me ! " ) The " Invisible Hand " crash lands on Coruscant ' s surface where Anakin and Obi - Wan argue who should go after Grievous until Yoda , emerging from the wreckage , makes the decision to send his former master . Frustrated and unhappy with his seemingly restricted lifestyle as well as though he were being treated like a child , Anakin walks angrily away from the wreckage , but is stopped by Palpatine , who sows discord between Anakin and Yoda by telling him that Yoda does not see his full potential , but he can . When Palpatine ' s head swivels between himself and the identity of Darth Sidious , Anakin comes to the conclusion that Palpatine is a Sith Lord . Mace Windu decides to investigate . Meanwhile , on Utapau , Obi - Wan finds Grievous hiding behind a pillar suggested by Tion Medon , and the two engage in a lightsaber duel that results in Obi - Wan slicing off three of the general ' s hands . Back on Coruscant , Master Windu confronts Palpatine alone and discovers that he is indeed Darth Sidious . Windu manages to gain the upper hand in the fight until Anakin arrives . Palpatine convinces Anakin that the Jedi is attacking him as he holds him off with force lightning . Anakin , after three seconds of impasse , disarms Windu with a force push , and Palpatine kills the Jedi Master by scorching him with the lightning and sending him out the window . With Anakin now rechristened into his new Sith apprentice Darth Vader , Palpatine puts Order 66 into action . On Utapau , Grievous falls to his death when his TSMEU - 6 personal wheel bike tumbles over the cliff in reverse . Obi - Wan announces their victory , but elation is cut as he witnesses Commander Cody and the Clones departing on LAAT gunships and ARC - 170 starfighters . Narrating the story , 3PO mentions the Jedi Purge and the rise of the Galactic Empire in passing . Obi - Wan confronts Vader on Mustafar , and after a heated exchange of words , the two lock their lightsabers in combat while Yoda squares off with Sidious in the Senate Building . Yoda apparently escapes while a Force push gone awry sends Anakin falling into the lava . With his transformation into Darth Vader complete , Anakin fully embraces the dark side of the Force while his children Luke and Leia are born . As he finishes his story , 3PO catches a glimpse of R2 and the mysterious kidnapper on a holocam video leaving on a shuttle . After urging the gatekeeper droid to zoom in on the picture , 3PO learns that they are heading to Mos Eisley on the planet Tatooine and books a shuttle there . Meanwhile , Admiral Ackbar has to deal with " Daisy Mae " being towed away by a tow truck , but not until after 3PO thanks him for the ride .
