Battle of Hypori / Legends The Battle of Hypori of the Clone Wars took place on the planet Hypori four standard months after the First Battle of Geonosis . Notable as the first public appearance of General Grievous , Supreme Commander of the Separatist Droid Army , the battle was initially intended as a Republic raid on the Separatist foundries on Hypori , based on intelligence gathered by Jedi Master Daakman Barrek , who led the attack . However , the Separatist forces were waiting for the Republic assault , and it quickly turned into slaughter , with the Republic forces shot down . As Grievous ' ground forces advanced on the wreckage where the Jedi survivors were holed up , Grievous personally defeated Daakman Barrek as he called for help before calling off his forces . Grievous entered the wreckage himself and engaged the Jedi , killing Sha ' a Gi and Tarr Seirr and besting Aayla Secura , K ' Kruhk and Shaak Ti . As the General prepared to finish the last Jedi standing , Ki - Adi - Mundi , a squad of Advanced Recon Commandos sent by Obi - Wan Kenobi on Muunilinst burst in on the duel . Their superior firepower forced the lone cyborg to retreat , and all the Jedi survivors were extracted , save K ' Kruhk , who was thought dead . Grievous was ultimately unconcerned by their escape , feeling that it was little more than prolonging the inevitable . The battle . The Battle of Hypori was the result of intelligence gathered by Jedi Master Daakman Barrek and his Padawan , Sha ' a Gi , which indicated the presence of a large droid factory on Hypori . A Jedi task force , consisting of Barrek and his Padawan , along with Ki - Adi - Mundi , Aayla Secura , Shaak Ti , K ' Kruhk , and Tarr Seirr , was dispatched to the planet to destroy the factory , reinforced by an army of clone troopers . They were to be led by Barrek , due to his superior knowledge of industrial matters . As the Republic ships emerged from hyperspace , orbital mines caused the majority of the transports to crash behind the Separatists ' lines . The task force was quickly surrounded by the massive droid army that was stationed on the planet , and all the clone troopers present were quickly slaughtered . The seven remaining Jedi retreated to an area of the planet where a large number of the " Acclamator " - class assault ships had crash landed . As they were retreating , Master Barrek attempted to send out a distress call to any nearby Jedi . As Barrek was doing this , he was suddenly attacked by the Supreme Commander of the Separatist Droid Army , General Grievous . Barrek was able to make contact with General Obi - Wan Kenobi and Commander Anakin Skywalker on Muunilinst and requested an " immediate evac " from Hypori , telling Kenobi that they were being hunted before being slain by Grievous . Jedi versus Grievous . The six remaining Jedi were left surrounded by the hordes of B2 super battle droids produced by the factory . Announced to by Grievous that they would receive a " warrior ' s death , " the Jedi waited as Grievous approached . As Grievous drew near , his footsteps became consistently louder until Sha ' a Gi was overwhelmed with fear and charged into the open . Grievous quickly crushed him with his metallic body before leaping back out of sight . As the Jedi retreated into the wreckage , Grievous suddenly attacked , dropping from the wreckage above and brandishing two lightsabers . After a few moments of fencing , Grievous began to focus his efforts on Mundi . The Jedi Master promptly leaped onto a ledge above and launched a powerful Force push at Grievous . The cyborg quickly dodged , leaping onto one of the larger pieces of wreckage and using it as a springboard to launch himself back at the Jedi . Landing in a crouch , Grievous was promptly engaged by K ' Kruhk . Despite the Whiphid ' s tenacity , Grievous defeated him with a quick slash across the belly and a rapid overhand blow . Leaving K ' Kruhk for dead , Grievous turned to the other Jedi . Defending himself against a telekinetic assault by Shaak Ti , Grievous grabbed Tarr Seirr with his clawed foot and crushed the young Cerean ' s head against the ground . As Aayla Secura charged , Grievous grabbed her with his other foot and performed a backflip , throwing her into the ceiling along with Seirr ' s corpse . Left with only Ki - Adi - Mundi and Shaak Ti to battle , Grievous fended them off by spinning his hands , rotating his dual - lightsabers in a buzzsaw - like fashion . As the two were temporarily taken aback by this , Grievous used the distraction to kick Mundi into a nearby pillar before unleashing a frenzy of blows against Shaak Ti . As Mundi rushed to her aid , Grievous disarmed her and sent a massive finishing blow her way . While Shaak Ti was able to protect herself from the slash with the Force , the kinetic energy it imparted was enough to throw her off her feet and hurl her into a wall of wreckage . As Grievous turned on Ki - Adi - Mundi , the Jedi attempted to retrieve his dropped lightsaber , but Grievous pounced on it , seizing it with one of his clawed feet . In response , Ki - Adi telekinetically summoned one of the blades hanging on Grievous ' belt . Grievous , not being a Force - sensitive , and having all of his limbs occupied , was unable to prevent this . As Mundi lifted the weapon into a guard , the two , Jedi and cyborg , eyed each other . Grievous broke the stare and leaped at Mundi . ARC rescue team . While the Jedi had been engaging Grievous , a group of 10 Advanced Recon Commando lieutenants led by Captain Fordo had been rushing to Hypori via gunship . As the ship approached the battlefield and wreckage — flying so low that the ship clipped the heads off several battle droids — it dropped a series of command detonation explosives , which the droids ignored as they fired at the gunship . Blowing a hole in the side of the wreckage and swooping in , the gunship dropped off Fordo and his team before hovering up to a large hole in the wreckage to fend off the droid reinforcements . Fordo and his team charged into the wreckage , coming upon the final bout between Grievous and Ki - Adi - Mundi . Just as he was about to finish the disarmed Mundi , Grievous noticed the ARCs , who promptly began firing . As Mundi reclaimed his discarded lightsaber , Grievous quickly retreated into the wreckage . Dodging fire , Grievous ran up the wall of the wreckage before leaping down at the ARCs . Landing in their midst , Grievous viciously cut down four of the ARCs before Fordo called in for backup . Backup took the form of the gunship , which began firing on Grievous . Again retreating into the wreckage , Grievous dodged the blasterfire and missiles with a number of dazzling leaps and flips , cutting his way through the half - burned durasteel . With Grievous thus occupied , the surviving ARCs and Jedi retreated , despite Mundi ' s objections . The ARC troopers , covering their withdrawal , activated the command detonation explosives that their gunship had dropped earlier , destroying many of the droids surrounding the crashed ship to clear an escape path . Aftermath . Other than Ki - Adi - Mundi , the surviving Jedi included Shaak Ti and Aayla Secura . K ' Kruhk was thought dead but had in fact gone into a deep healing trance , during which his heart - beat and breathing had decreased to barely noticeable levels . While they retreated , Grievous quietly claimed his trophies from the slain and defeated Jedi , notably the lightsaber of the fallen K ' Kruhk . As he watched their gunship vanish into the distance , Grievous mused that they were only prolonging the inevitable . Grievous ' actions that day led Master Plo Koon of the Jedi High Council to dub him as the Butcher of Hypori . After the battle , Aayla Secura was assigned to the 327th Star Corps . Jedi Knight Etain Tur - Mukan later thought that it was unfair that clones had been sent to rescue Jedi on Hypori , as Jedi were never sent to rescue clones . Behind the scenes . Originally , the last chapter was going to involve Anakin and Obi - Wan having to fight a regenerated Durge . This was changed when George Lucas requested that they introduce General Grievous .
