G0 - T0 infrastructure planning system The G0 - T0 infrastructure planning system was a second - degree planning droid produced by the Aratech Repulsor Company and designed and programmed to serve as a central organizational hub for planetary rebuilding efforts . History . The Aratech Repulsor Company began research and development of the G0 - T0 droid following the devastation of the Great Sith War and during the years leading up to the Mandalorian Wars , when the Galactic Republic needed assistance in rebuilding the galaxy ' s infrastructure . As a part of the company ' s investment in the Republic ' s restoration efforts under the Coruscant Financial Exchange Establishment Act in 3985 BBY , the first prototype G0 - T0 models helped with the reconstruction efforts after the Great Sith War . It was not until 3955 BBY that Supreme Chancellor Cressa put the droids to greatest use by assigning them to rebuilding the galaxy after the Jedi Civil War . Each G0 - T0 droid was given a unique identifier corresponding with the planet it assisted . It could plug directly into planetary computer networks and thus oversee construction efforts across the entire planet , using its specialized software to maximize efficiency and minimize mistakes . The G0 - T0 had a high level of artificial intelligence , with enough authority to manage planetary administration and request supplies and command organic workers . It could also consider options that would benefit the entire Republic within the confines of law and regulation , thus expanding its scope yet further . Unfortunately , the massive amounts of data flowing through a G0 - T0 often corrupted the droid ' s memory , causing it to rapidly develop both a personality and independent motivations . This presented something of a worry for the designers at Aratech . Such a massive intelligence was obviously of great use to the Republic , but if not checked , it could become unstable and threaten security . Thus , Aratech limited its machine interface capabilities by placing the G0 - T0 ' s circuitry into the body of a spherical repulsorlift droid . Despite this , fears over the G0 - T0 ' s capabilities became founded when the unit assigned to the Telos IV Restoration Project happened upon a paradox in his duties . The droid felt it was unable to effectively help the Republic within its programmed parameters , and so broke free of his restrictions in order to follow his primary directive . G0 - T0 set about eliminating threats to galactic stability , and to this end , began posting bounties on Jedi and Sith with the help of HK - 50 assassin droids produced from a droid factory G0 - T0 had set up on Telos . G0 - T0 ' s secret agenda became masked behind a public face ; that of the crime lord " Goto " , an alter ego projected as a hologram by the droid while he continued work on Telos . Ultimately , G0 - T0 was destroyed on Malachor V , but his actions seemed to have set a precedent for G0 - T0 units around the galaxy . Within five years , other G0 - T0 droids had also broken free of their programming , such as G0 - T0 - Telerath , who temporarily seized control over one of the galaxy ' s most prominent financial institutions , causing an economic emergency when it demanded control of the Coruscant Financial Exchange , or those stationed in the Gordian Reach , who set themselves up as dictators , cutting off all connections to the HoloNet and blockading in - system hyperlane s . They then announced their takeover of the sixteen worlds now part of the independent territory known as 400100500260026 . It took the might of the Republic Navy to put down this insurrection , in a highly - publicized campaign . The repercussions of such actions had a devastating impact , not only on the Aratech company , but also the citizens of the galaxy . From then on , the image of these spherical , black droids conjured thoughts of fear and dread , and was partially responsible for the reputation of the IT - O Interrogator , whose design echoed that of the G0 - T0 droid for maximum psychological effect . Behind the scenes . In " " , G0 - T0 states that he changed his droid shell into something more intimidating . This idea conflicts with the information above , as it implies that the Republic Infrastructure Droid has always had the IT - O droid shell ( despite the significant size difference between the two models ) . Furthermore , within the game , particularly aboard Goto ' s yacht , there are several " guard droids " that share the IT - O and G0 - T0 frame .
