When it comes to raw power, Emperor Palpatine, also known as Darth Sidious, edges out Darth Vader. As the Sith Master, Palpatine possesses an unparalleled command of the dark side, excelling in manipulation, political strategy, and raw Force abilities, including Force lightning and Sith alchemy. Darth Vader, though immensely powerful and skilled, is limited by his physical injuries sustained during his duel with Obi-Wan Kenobi, which significantly diminished his potential as the Chosen One. However, Vader’s resilience, combat prowess, and connection to the Force make him a formidable enforcer. Ultimately, Palpatine’s mastery and cunning place him at the top.
