IG - 101 / Legends IG - 101 was one of several of General Grievous ' s IG - 100 MagnaGuards . Trained in the seven forms of lightsaber combat by Grievous , IG - 101 was a formidable martial combatant , more than a match for most opponents , and even able to compete with Jedi . He participated in the Battle of Coruscant towards the end of the Clone Wars , accompanying Grievous aboard his flagship , the " Invisible Hand " . He and IG - 102 retrieved Anakin Skywalker and Obi - Wan Kenobi when they were captured by security forces aboard the " Hand " , bringing them before Grievous . When the Jedi escaped captivity and fought back , Grievous ordered IG - 101 and 102 to engage the jedi . Focusing on Kenobi , 101 ' s formidable combat skills allowed him to quickly gain ground on the Jedi , though his repetitive fighting form proved to be his undoing , and he was decapitated and dismembered by his opponent . Biography . IG - 101 , along with IG - 102 , served as the cyborg General ' s bodyguards onboard " Invisible Hand " during the Battle of Coruscant in 19 BBY . He and IG - 102 personally led the force that successfully captured Anakin Skywalker and Obi - Wan Kenobi during their botched rescue attempt of Supreme Chancellor Palpatine , as well as Skywalker ' s astromech droid , R2 - D2 . Bringing the Jedi before Grievous on the " Invisible Hand " s bridge , they took up positions behind the General while the cyborg gloated over the Jedi . However , all on the bridge were distracted by a pyrotechnics display unleashed by Skywalker ' s astromech , allowing Kenobi to retrieve his lightsaber from the sheath pocket inside Grievous ' cape , where it had been deposited as the newest addition to the cyborg ' s collection . Kenobi quickly cut his bonds and freed Skywalker , who wasted no time retrieving his own weapon . With the Jedi rearmed , Grievous ordered IG - 101 and 102 to engage , and " make them suffer " . The two droids initially teamed up on Kenobi , but IG - 102 broke off to take Skywalker , leaving 101 to deal with Kenobi . Despite the Jedi ' s best efforts , 101 managed to drive him back towards the front of the bridge . However , Kenobi was able to pin the MagnaGuard ' s electrostaff against a console and decapitate the droid . However , as MagnaGuard primary processors and had a secondary ' eye ' in their chest , 101 was able to continue fighting . Opting for a one - handed hold of his staff , IG - 101 began utilizing twirling movements to keep up a constant wave - front of attack , gaining even more ground on the Jedi . However , due to the repetitive nature of this move , Kenobi was able to find an opening . The Jedi exploited it ; when the MagnaGuard brought his weapon horizontal , Kenobi used a horizontal slash to get inside the droid ' s guard , simultaneously removing 101 ' s weapon arm and cleaving him in half at the chest . IG - 101 ' s still standing body literally fell to pieces with a metallic groan , even as he attempted to continue attacking Kenobi , grasping at him impotently . Abilities and traits . Abilities and skills . IG - 101 was trained in all seven forms of lightsaber combat by Grievous with coaching from Dooku , just like all other MagnaGuard ' s . Executing his moves almost faster than the human eye could follow , IG - 101 demonstrated a lack of hesitation and almost total commitment . However , again like all other MagnaGuard ' s , 101 could be confused by unpredictability due to his own repetitive combat style , which proved to be his downfall , when Kenobi got inside his guard and bisected him . Programming and traits . IG - 101 , like all MagnaGuards , was programmed to demonstrate loyalty to General Grievous and to learn from experience , his own leading him to develop a somewhat aggressive and pragmatic personality . While he never disobeyed orders , he did openly question them , such as when he inquired as to why he and IG - 102 weren ' t allowed to simply execute Kenobi and Skywalker on the spot when they were captured . Grievous appeared to respect the droid enough to provide him with an explanation rather than berate him for insubordination . His more aggressive traits came to light when he battled Kenobi , continuing to fight even after beheaded . He even attempted to keep it up after being disarmed and bisected , grasping in Kenobi ' s direction as his body fell to pieces . Behind the scenes . In the " Revenge of the Sith " novelization , IG - 101 is said to lose an arm and a leg rather than his head . He is also mentioned making improbable threats to Kenobi regarding his staff and Kenobi ' s bodily orifices .
