Starweird

Starweirds were a species of incorporeal humanoids found only in space. Tall and gaunt, they possessed long, sharp talons, wild white hair, and glowing eyes. The creatures appeared to spacers repairing their starships in space, or aboard vessels traveling through hyperspace. A starweird would choose a target, and, after being spotted, emit a telepathic scream that caused fear in most individuals. The starweird would then attack its victim. Starweirds were capable of using the Force, and held a strong hatred for Force-users, leading some Jedi to believe that they were apparitions created by the dark side of the Force.

Biology and appearance
Starweirds were incorporeal, humanoid, Force-using creatures found only in the vacuum of space. They were very tall and extremely gaunt&mdash;to the point of almost being skeletal&mdash;and wore ephemeral rags that hung from their arms. Starweirds had long, wild white hair that floated around their heads even in gravity. The creatures had pale skin, and their faces were desiccated. However, specific accounts of what a starweird's face looked like varied, with many witnesses stating that the creature's face somewhat resembled their own. Starweirds had large, toothy mouths and eyes that glowed in a way described as eerie. Their arms were bony and ended in hands with large, sharp talons. Starweirds did not walk; rather, they hovered. The creatures did not speak and had no known language. The species was capable of seeing up to twenty meters in complete darkness. Starweirds could use the Force powers Drain Energy, Force Grip, Force lightning, and Force Sight. They had no ecological role, and after dying, a starweird left no traces of itself behind.

Behavior
Starweirds would typically appear to spacers repairing their damaged starship in deep space, or manifest aboard a ship traveling in hyperspace. Upon being spotted, starweirds released a loud, piercing telepathic shriek. Due to the call's telepathic nature, it could be heard even in the vacuum of space. This scream often caused listeners to cower in fear or attempt to flee, although some did try to fight back despite the terror they felt. After issuing this shriek, starweirds would set upon their foe, shredding them with their sharp claws. A starweird would choose one target and focus on that individual.

The creatures were noted for having a particular hatred for Force-sensitives. Upon encountering a Force-user, they would mindlessly concentrate on killing that individual.

History
Starweirds were found solely in deep space. They were considered a mysterious species, and some Jedi hypothesized that they were physical manifestations of the dark side of the Force. However, little evidence supported that theory.

Behind the scenes
Starweirds were created for the sourcebook Ultimate Adversaries, and later given an entry in The Complete Star Wars Encyclopedia.
