Official description . " When a band of bounty hunter s leads Anakin and Mace into a deadly trap on Vanqor , it ' s up to R2 - D2 to battle his way back to Coruscant and warn the Jedi . " Plot . The " Venator " - class Star Destroyer " Endurance " has crashed on the planet Vanqor after the sabotage caused by young Boba Fett in his quest to kill Jedi Master Mace Windu . Hoping that Admiral Kilian , Commander Ponds and others may still be alive , Windu and Anakin Skywalker transfer the survivors to a Republic medical ship before heading down to the planet to look for survivors . Skywalker points out upon coming across the ship that , while it is in a terrible shape , the bridge appears to be in one piece . The two Jedi set down behind the ship , at which point R2 - D2 beeps that he has a ' bad feeling about this place ' . Windu chastises Skywalker for encouraging individuality in his droid . Windu , Skywalker , R2 and R8 - B7 proceed to the ship , unaware of gundark s following them . Once inside , the Jedi come across clone trooper s killed not by the crash but by execution ; Windu theorizes that those who tried to assassinate him may have come down looking for his body and killed the survivors . The droids are sent to search for survivors while the Jedi head to the bridge . In the process of their search R2 and R8 are attacked by a pair of gundarks : R8 is ripped apart and R2 is knocked across the floor . On the bridge , Windu and Skywalker come across several dead clones , but note there is no sign of the Admiral or Ponds . Windu reports this to the medical ship in orbit , which proceeds to leave for the nearest Republic medical station . Noticing a Mandalorian helmet sitting on a piece of rubble , Skywalker advances . Windu , spotting the helmet , is reminded of Jango Fett , the template for the Clone army , whom Windu killed on Geonosis , and then remembers his son , Boba , who watched his father die at Windu ' s hands . Too late , Windu uses the Force to pull Skywalker away from the helmet , which explodes , severely damaging the bridge and causing debris to rain down on the gundarks that were advancing on R2 ; one is killed while the other flees . In the distance Aurra Sing , Bossk , Boba and Castas watch the explosion with satisfaction . Boba insists on finding Windu ' s body , but his companions initially refuse , stating they have enough to sell Count Dooku with their three hostages ; Admiral Kilian , Commander Ponds , and a navigation officer . In the end Aurra and Boba win out , leaving Bossk to guard the hostages as they head to the downed ship . R2 , now realizing the Jedi may be in danger , heads to the bridge and finds Windu unconscious and Skywalker wounded , both trapped under rubble . As the droid tries to move the debris , he causes the bridge to shudder , and Skywalker warns him against it . Instead he instructs his droid to head back to the Jedi starfighters and send a message to the Jedi Temple on Coruscant for help . R2 proceeds to leave the bridge , but spots the bounty hunter s approaching and instead decides to try and halt their advance . He first pushes debris down a tunnel the bounty hunters are coming through , then closes the doors on them . When they come up another tunnel , he pushes yet more debris and boxes at them , before detaching a grenade from a dead clone and dropping that down the tunnel . Deterred , Aurra declares that they will instead use " Slave I " to destroy the remains of the ship , thereby ensuring the Jedi ' s death . R2 then proceeds to the Jedi starfighters , but is accosted on the way by the remaining gundark . Using quick thinking , the droid attaches the gundark , via a cable , to one of the starfighters and activates the fighter ' s engines , crashing it some miles away and killing the gundark . Having witnessed the explosion , and realizing that it came from near the Jedi starfighters , the bounty hunters believe Windu has survived and jam all communications before heading to the location of the starfighters in " Slave I " . R2 activates the remaining starfighter and pilots it away from " Slave I " , now shooting at it , and into the atmosphere . Seeing this , Windu states that his astromech was meant to get help , not abandon them , but Anakin returns his faith in R2 . Avoiding the blaster fire from " Slave I " , the astromech droid gets into space , but its communication device is destroyed : the only solution now is to use the hyperdrive rings and get to Coruscant . Realizing the droid ' s plan , Boba fires at the hyperdrive rings but succeeds only in destroying one , allowing R2 to use the other to escape . Aurra states not to worry , as she can draw Windu to her using the hostages , before " Slave I " makes the jump to hyperspace . On Coruscant , R2 interrupted a meeting with Plo Koon ' s droid and replays Anakin ' s message to several other Jedi . Plo Koon and Ahsoka Tano make their way to Vanqor with rescue ships , and Corporal Comet , along with Commander Wolffe , helps the injured Jedi as the bridge of the " Endurance " collapsed . Mace , at the end , compliments R2 on his bravery .
