WAC - 47 / Legends WAC - 47 was a masculine - programmed DUM - series pit droid during the Clone Wars . He served with Clone Commander Neyo and was later transferred to D - Squad . Biography . Stealth Mission . Around 20 BBY , WAC - 47 helped D - Squad infiltrate a Confederacy of Independent Systems dreadnought and steal an encryption module used by the Separatists . Immediately , this overenthusiastic , bumbling droid went off on a bad start . He arrived at the Jedi Temple late , much to the displeasure of Mace Windu . When Colonel Meebur Gascon arrived , WAC was instantly at odds with the Colonel , often mistakenly referring to him as Corporal and contradicting Gascon ' s strict ways . When the other droids of D - Squad went to get modifications from the Parwan doctor Gubacher , WAC was instructed to stay with their ship , as he was supposed to only be the pilot . WAC was not happy with this , and when they were approaching the Separatist fleet , he set a collision course with the dreadnought . He was trying to show Gascon that he was more than a pilot , but Gascon was very angry with WAC anyway as their ship was caught in a tractor beam . At one point , the squad was faced with one of their objectives to remove two B2 super battle droids guarding the comm vault . WAC volunteered to distract them by claiming to have been sent by General Grievous to test the vault ' s security and locked them in an elevator , allowing the squad to go on . They successfully reached their destination with only the loss of M5 - BZ . When they were about to extract their encryption module , the super tactical droid Aut - O burst into the room . R2 - D2 turned the gravity in the room off , and a skirmish between D - Squad and the Separatists broke out . Aut - O was eventually defeated and the squad was able to escape safely with the module . On their way out of the dreadnought , WAC and R2 - D2 paused at the destroyed body of M5 - BZ . While Gascon did not approve at first , they were allowed to bring the droid with them for repairs once they got home . Although originally enemies , WAC seemed to grow on Gascon as he commended all of them for their bravery in the mission . This was the first time WAC correctly called Gascon a Colonel , as well . Stranded . As the astromech got to work on BZ , WAC noticed blips on the ship sensors . He got up to inform Gascon that there were comets in their path , but added that he would at least have an excuse if his mission failed . Gascon hurried to the cockpit as the hyperspace window turned red . WAC dropped them out of hyperspace before they could collide , but the shuttle sustained damage in the middle of the swarm . The mechs managed to repair the damage , restoring power to the engines , but they were forced into a crash - landing on Abafar . Though Gascon insisted they stay at the ship , the mechs took off with the encryption module , hoping to find civilization . WAC chased after them , telling Gascon that perhaps the Republic would give himself a promotion by delivering the module , prompting Gascon to chase after the droids . As the group traveled across the featureless waste , Gascon once again began to lose his temper and claimed himself better due to his training and supposed mental flexibility while the droids " merely " acted on their programming . WAC , however , managed to point out the flaws in Gascon ' s reasoning , and a chance encounter with another shipwreck and the dead remnants of its crew teared the last shred of resolve from Gascon . In his desperation , he began to lose his mind , and as a result , when WAC impertinently announced himself the new leader of the group , he found himself overruled and abandoned by the others . WAC remained with Gascon as the Colonel bemoaned the hopelessness of his predicament . The pit droid told him that it was not in his programming to give up and asked Gascon why he feels this way . This restores Gascon ' s resolve , as he decides to think outside the box . At that moment , a stampede of native flightless birds rushed past them . The duo hitched a ride on the birds , Gascon reasoning that their instincts would lead them to safety . Sure enough , the birds brought them to the town of Pons Ora , where they found the rest of D - Squad . Before taking a much needed drink from an oasis , Gascon thanked WAC for helping him and field promotes him to the rank of Corporal . This pleases WAC , who goes on to boasting of his new rank to the astromechs . Return home . As they made their way through town , Gascon and WAC separated from the rest of the squad so the former could get some much needed refreshment . But upon entering a diner , they were rudely shooed out by the Sullustan cook , Borkus . Though Gascon vowed revenge , WAC pointed out that he was unlikely to get it . The pit droid then spotted a swarm of insects scurrying to the side of the diner , where the garbage was . Though Gascon was disgusted by the thought of eating leftovers , he saw no alternative . But before he could take a bite , the diner ' s dish washer , Gregor , came out to dump more waste . He apologized to Gascon and offered to give him food on the side . However , the Colonel stared at Gregor , identifying him as a clone that apparently had amnesia . Before they could press any further , Gregor was called back into the diner . Gascon and WAC rendezvoused with the astromechs , who reported the presence of Separatists on the planet . Though Gascon ' s deductive reasoning , they found a landing zone , albeit heavily guarded . Gascon said they had to stealthily make their way to the docked shuttle , and the droids pointed out that the Separatists may have been on the lookout for them after their mission to the dreadnaught . Therefore , the group decided to enlist Gregor ' s aid . They followed the clone to his apartment and got his attention with a hologram of Captain Rex . R2 was able to identify him as a clone commando from his ID tag , presumed missing in action in the Battle of Sarrish . With his memory partially restored , Gregor agreed to help them and they went to the diner to search for his equipment , where they were confronted by Borkus , who had been secretly hiding his gear . D - Squad was able to get the drop on the Sullustan , leaving him bound on the diner floor . As they prepared to leave , Borkus revealed that the Separatists were mining Rhydonium to assault a Republic cruiser in orbit . Gregor provided cover fire for D - Squad as they made their way to the shuttle . But the battle droids attempt to stop them . One stray shot hit a fuel canister , knocking down BZ and Gascon inside him . Gascon urged WAC to leave him , an order he quickly complied with . He quickly met up with Gregor , who went back for Gascon and BZ and stayed behind to cover D - Squad ' s escape . As WAC got the shuttle in the air , he asked Gascon where Gregor was . The Colonel stated that the clone commando was sacrificing himself to ensure they survived to tell of his tale . D - Squad then departed Abafar for the Republic . D - Squad then disembarked on the Republic cruiser in orbit of Abafar , where they discovered that the ship had been commandeered by Separatists . Upon encountering surviving Republic droids , D - Squad learns that the Separatists have loaded large quantities of rhydonium aboard the cruiser , intending to use it as a explosive weapon at a space station in the Carida system , the site of the Republic Strategy conference . But before they could act on this information , Gascon and the Republic chased a buzz droid to stop it from alerting the other battle droids . They chased the buzz droid into one of the gun batteries , only to find a whole swarm waiting for them . Surrounded , Artoo created a ring of fire around his compatriots to keep the buzz droids from getting at them . M5 - BZ then made a daring move to blow the buzz droids out the airlock . The Republic droids quickly magnetized their feet to avoid being sucked out , but Beezee wasn ' t so lucky and was sucked out into hyperspace along with the buzz droids . Vowing to not let Beezee ' s sacrifice be in vain , Gascon came up with a plan to thwart the Separatist plot . As he led the droids back to their shuttle , Artoo went for the bomb trigger , intending to reprogram it to trigger the rhydonium to detonate prematurely . Unfortunately , a super tactical droid was already prepping the detonator . Though Gascon wanted to go back for Artoo , WAC initiated takeoff . D - Squad managed to get to safety as Artoo managed to complete his task , destroying the cruiser before it could tear apart the station . Anakin Skywalker dispatched salvage teams into the wreckage in search of the heroic astromech , who managed to find Artoo and repair him .
