Lightsabers are fictional weapons that appear in Star Wars Universe. Lightsabers are classified as energy weapons, consisting of a luminescent plasma blade emitted from a metal hilt. It is prominently used by the Jedi and Sith Orders, representing the light and dark sides of the Force, respectively. While the Jedi typically use blue and green lightsabers, the Sith exclusively wield red-bladed sabers, with the color determined by the kyber crystal influenced by the wielder and the Force.
