Force scream A Force scream was an involuntary Force exertion manifested by those whose alignment was with the dark side of the Force . It was a scream , of strong frustration , rage , or grief , emitted through the Force . Description . If a Dark Jedi or Sith Lord was being beaten and frustrated by his foe , he might let out an enraged scream ( amplified through the Force ) that triggered shock waves that rippled through the Force . This caused devastation to any that were unfortunate enough to be in proximity . Like many dark side Force powers , it allowed the user to use powerful negative emotions as a weapon , albeit involuntarily in this case . The Force scream had been called " a wave of hatred , amplified and fueled by the dark side , that is capable of smashing through mental and physical defenses with ease . " A number of references to Dark Jedi in Old Republic archives often mentioned the Dark Jedi violently losing control in the final moments of battle . Notable uses . After being told that the dark side was the only means to save himself in the ruins of the Sith temple on Korriban by the ancient Sith Lord Freedon Nadd , Exar Kun let out an enormous scream through the Force . Such was the power of his scream that Masters Vodo - Siosk Baas and Arca Jeth both heard and felt Kun ' s anguish many light year s away while on the planet Deneba . Freedon Nadd himself let out a powerful scream through the Force , after dying a second death at the hands of his pupil Exar Kun . Kun also released a scream through the Force at that moment , in triumph over Nadd and after giving himself over fully to the dark side . Nomi Sunrider and Master Vodo Baas heard both screams through the Force , and Nomi mistakenly thought that Exar ' s scream was that of Ulic Qel - Droma . Master Vodo knew better however , realizing the voice of his former student . He felt the disturbance in the Force , noting that if felt as if one great power had fallen and another had had risen in its place . Ulic Qel - Droma , having been subjected to Krath leader Satal Keto ' s torture droid , refused to reveal the truth behind his coming to Empress Teta . But when Satal injected him with Sith poison , a powerful toxin that amplified an individual ' s rage and opened them further to the dark side , Ulic let out a scream through the Force so strong that it obliterated the machinery he was harnessed to , as well as the torture droid . Later , after he dueled and killed Satal , he let out a Force scream that wrecked the Iron Citadel balcony and knocked both Nomi Sunrider and his brother Cay from their feet . Darth Malak , Darth Traya , and Darth Nihilus were known to use Force scream . Three centuries later , during the Battle of Ord Radama , Darth Malgus let out a Force scream after sensing the deaths of Darth Venemal and the crew of a " Harrower " - class dreadnaught . In the process , the scream not only made the " Lindworm " bridge shake and its crew ' s ears bleed , but also overload the fuel cells of nearby " Aurek " - class starfighters . Darth Baras also let out a scream after some failed attempts to get information of a captured Republic spy named Grik Sonosan , shaking the walls of his office in the Imperial Citadel . After defeating Asajj Ventress on Yavin 4 , Anakin Skywalker released his rage while standing on the precipice where Ventress seemingly fell to her death , and let out a powerful scream through the Force . He also screamed Count Dooku ' s name during the recapture of Tythe ; the magnitude and wrath of the scream caused the building ' s entire roof to collapse , incapacitating himself and his master , Obi - Wan Kenobi , as well as Dooku . By far his most infamous use of it was upon learning of the death of his wife , Padmé Amidala , after his transformation into Darth Vader . This caused him to involuntarily unleash a powerful Force scream of shame , rage , and grief , severely damaging the medical chamber and the droids within it . The scream did not stop there , however . It echoed throughout the whole facility , causing the sensors to go haywire and one medical worker to permanently lose his hearing . Many staff members believed this scream came from a ghost , carrying out the death cries of the Clone Wars . Darth Maul used Force scream while he was dueling Obi - Wan Kenobi and Asajj Ventress on the Turtle Tanker above Raydonia . Ventress and Kenobi were escaping , and Maul let out a feral roar of anger , as he tried to give chase . On Wayland , Joruus C ' baoth caused the ceiling of the Mount Tantiss storehouse throne room to collapse through the power of his scream while battling Luke Skywalker and Mara Jade . Darth Caedus used Force scream to warn his lover , Queen Mother Tenel Ka Djo , and their daughter about a nanovirus that was about to be released aboard their ship during his final clash with his twin sister . Jaina killed him before he could finish his message , but Djo heard him and escaped the nanovirus with Allana . Darth Sidious used a Force scream against members of the Jedi council during their attempt to arrest him . The scream threw the Jedi off balance and allowed him to swiftly executed three of the four masters , with only Mace Windu surviving to engage Sidious in a duel .
