Mark I Power Guard Mark I Power Guards were the first model of soldiers augmented with the Power Guard Enhancement System , a supersoldier program developed by the Galactic Republic . When the Sith Lord Sadic acquired control of the Power Guard project in 3643 BBY , he manufactured Power Guards using refugees and wiped their minds , transforming them into mindless weapons for him to control . Mark I Power Guards were the weakest model of Power Guard but were equipped with advanced weapons and armor like later models . Several Mark I Power Guards were left to defend the Power Guard Cybernetics Lab after Sadic moved the program elsewhere , though they were no match for a young Jedi Knight who arrived not long afterward . After Sadic ' s defeat , the entire project was scuttled . History . The Power Guard Enhancement System was developed by the Galactic Republic as part of the Republic superweapon initiative during the Cold War between the Republic and the Sith Empire . The Power Guard system was applied to willing recruits on the moon Nar Shaddaa , but in 3643 BBY , the Sith Lord Sadic seized control of the project and set about using it for his own ends . Instead of using willing volunteers , his forces began abducting refugees and forcing them to undergo the Power Guard process — but their minds were also wiped and programmed , giving Sadic droid - like supersoldiers . When a young Jedi Knight began disrupting Sadic ' s operations , Sadic relocated the Power Guard program to another location , leaving only a handful of Mark I Power Guards along with his subordinate Commander Graul at the original Power Guard Cybernetics Lab . The Jedi Knight and a companion soon located the facility and stormed the building . When the Jedi breached the main chamber , the Knight briefly spoke with Sadic via holocomm , and then Sadic activated the remaining Mark I Power Guards stored in the lab to support Graul . However , the Knight and a companion killed Graul and the Power Guards . The Power Guard program came to an end not long afterward , with the Republic destroying all of the program ' s files . Characteristics . A Mark I Power Guard was a supersoldier augmented with the Power Guard Enhancement System — an array of cybernetic enhancements and adrenal stimulants . Each Mark I Power Guard was a Human or humanoid individual who underwent the Power Guard modifications , and thus every individual Power Guard was unique in height , weight , and gender . The Power Guard system was originally intended to produce supersoldiers who retained their personalities and individualism , but when Sadic seized control of the project , he added mind - wiping and mental programming to the process , creating drone soldiers who followed his commands . Equipment . Each Power Guard was equipped with advanced armor based on the standard Republic trooper version and also carried an advanced blaster rifle and vibrostaff for combat . Behind the scenes . Mark I Power Guards first appeared in the Jedi Knight - class mission " Red Light , Black Heart " in " " , a video game released by BioWare in 2011 . The Power Guard project can either be salvaged for dark - side alignment points or destroyed for light - side alignment points , but as the Jedi Knight is a Republic character and thus assumed to make only the choices that reward light - side alignment points , this article assumes that the project was destroyed .
