Darth Nihilus had the power to consume entire planets and was basically the ethereal embodiment of the Dark Side. Also, he had a kickass mask that makes Darth Vader’s helmet look like a bonnet. It’s not hard to see why this Sith Lord was one of the most powerful ever in existence. Born a normal human, he was exposed to a catastrophic superweapon that left him with an insatiable need to feed on the Force. This condition eventually consumed his physical body, eroding it until nothing but a spirit remained, which he later bound to armor and a mask so as to have a visible presence. Realizing his potential, Darth Traya trained Nihilus in the ways of the Dark Side, which culminated in his nearly single-handedly exterminating the entire Jedi Order to fuel his power.
Nihilus is what you get when you combine Marvel’s Galactus with that crazy ghost from Spirited Away. So vast were his abilities that he could drain a planet of life and render it forever uninhabitable. Eventually, he lost all domain over his hunger, involuntarily devouring everything in his path and earning him the ominous title of Lord of Hunger. Of course, power doesn’t solely come from the ability to destroy, which is why his utter lack of control keeps Darth Nihilus from reaching the top spot. But rest assured, there are few Sith more deadly.
Lets get this guy in a movie
