Force scream

Force Scream was an involuntary reflex of a Dark Jedi as a result of frustration from battling an opponent. If a Dark Jedi 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, devastating both the Dark Jedi and those who were unfortunate enough to be in close proximity. 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.

Anakin Skywalker once screamed Count Dooku's name during the Battle of Tythe; the force and wrath of the scream caused an entire building's roof to collapse. When Emperor Palpatine told Darth Vader he had killed Padmé Amidala, Vader involuntarily did a Force Scream, though the loss of so much of his strength just crushed the walls of the medical facilaty and a few medical droids.
