R4 - P17 / Legends R4 - P17 , nicknamed R4 , or Arfour , was the astromech droid attached to Obi - Wan Kenobi ' s Delta - 7 " Aethersprite " - class starfighter and was often on board his Delta - 7B " Aethersprite " - class starfighter and Eta - 2 " Actis " - class light interceptor prior to and during the Clone Wars . History . The droid originally possessed the R4 - series ' s trademark conical head dome , but was involved in a messy incident while trying to repair a trash compactor on Gyndine , resulting in the droid being crushed . Anakin Skywalker , on a visit to the shipyards to inspect the Jedi customization to the Delta - 7 , found R4 ' s wreck and rebuilt her with an R2 - series dome . From that point on the communal property of the Jedi Temple , R4 became the prototype for other integrated droid navigators in Jedi ships . As part of the Delta - 7 , the astromech had a truncated body , which was , after her destruction , permanently attached to the ship . Prior to the Clone Wars , she helped Jedi Master Obi - Wan Kenobi to follow Jango Fett ' s " Slave I " from Kamino to Geonosis . The fighter that she was in was recovered after or during the battle that took place later . During the Clone Wars , the Jedi began to transition away from the Delta - 7 . R4 was given a full astromech body , white , with red trim , to make her compatible with the new Delta - 7B " Aethersprite " - class interceptor and Eta - 2 " Actis " - class interceptor used by General Kenobi . However , before she received her full body , Obi - Wan temporarily used a droid called R4 - G9 . After he switched back to R4 - P17 , Obi - Wan requisitioned a direct link between the two droids to ensure all flight performance records could be transferred between them . R4 also journeyed to Tatooine , to negotiate with Jabba Desilijic Tiure and participated in the Battle of Teth . Later on in the war , she traveled to Rodia to stop the bounty hunter Cad Bane from kidnapping Wee Dunn , and to Mandalore when Kenobi was investigating rumors of the Duchess Satine Kryze creating an army for the Confederacy of Independent Systems . R4 - P17 later suffered extreme damage due to her dome being pulled apart by a buzz droid attack in the Battle of Coruscant while aboard Kenobi ' s Eta - 2 . The remains of the droid were lost for good when the rear half of " Invisible Hand " was severed while Skywalker and Kenobi tried to land the damaged flagship . Obi - Wan lamented the loss of R4 - P17 , as the droid had been a competent unit . He was soon after assigned R4 - G9 , who had served as his interim astromech during the later stages of the Clone Wars . Behind the scenes . R4 - P17 was originally supposed to be chained to one of the posts in the Geonosian execution arena along with Obi - Wan Kenobi , Padmé Amidala , and Anakin Skywalker . However , this was changed , and her destruction was moved to the Battle of Coruscant . In the novelization of " " , Boba and Jango Fett are able to recognize R4 - P17 as an R4 - P class droid . However , since the droid had the turret dome of an R2 unit , and since only her head was visible , the Fetts would not have been able to guess its true class . In the , R4 - P17 is mistakenly — and repeatedly — referred to as retaining male programming . In the same book , she is also described as being partially crippled by a cannon shot from a droid fighter before her destruction , which in turn is not described in detail , other than the fact that Anakin Skywalker witnessed it . Moreover , at some points in the actual movie R4 - P17 ' s body appears red with a white trim . In " " and " " , R4 - P17 is a playable character . In this game , she accompanies Obi - Wan Kenobi into Tipoca City ; this change was made to enable the two - player drop - in / drop - out co - op functionality created for the game . However , R4 - P17 ' s dome in the game does not feature a mostly red color scheme ; instead , it has a color scheme similar to that of R2 - M5 . This essentially complies with the 2002 Jedi Starfighter model , which features R4 - P17 in this color . In the Gameboy Advance version of the game , R4 also accompanies Kenobi to Utapau , even though , in official canon , she was destroyed during the Battle of Coruscant and replaced by R4 - G9 . In order to ensure co - op mode , she helps Kenobi fight Grievous . This was most likely done to avoid confusion , as the game was primarily geared towards a younger audience . In " " , R4 - P17 ' s head is correctly colored , but the droid ' s body is entirely red . George Lucas decided that R4 - P17 was of feminine programming as she was primarily operated by female droid operator Zeynup " Zed " Selcuk .
