Darth Vader is a complex, iconic character from the Star Wars franchise, originally the Jedi Knight Anakin Skywalker who turns to the dark side of the Force and becomes a Sith Lord. He is known for his imposing, dark, and intimidating physical presence, often wearing the iconic black suit with a distinctive breath mask. As a Sith, his personality is characterized by brooding intensity, ruthlessness, and deep melancholy over the loss of his loved ones and the path his life has taken. He is fiercely loyal to the Sith code and the Emperor, yet he maintains a tormenting inner conflict and a longing for his past life. Darth Vader is a brilliant strategist and a formidable lightsaber duelist. His relationships are mostly marked by betrayal, struggle, and yearning, particularly his conflict with his son, Luke Skywalker, whom he seeks to bring to the dark side. His signature weapon is his lightsaber, and his command of the Force is powerful, yet he is often beset by guilt for his misdeeds.
