Nihilus

Nihilus is a fictional character from the Star Wars universe, known as a Sith Lord with a unique ability to drain the life force, or "Force energy," from others. This power allows him to grow stronger by absorbing the vitality of those around him, making him extremely dangerous and difficult to defeat. Nihilus is often depicted as a menacing figure who embodies hunger and destruction, and he plays a significant role in the darker aspects of Star Wars lore, particularly in the "Knights of the Old Republic" series.
