Not only is Darth Vader the best and scariest villain in Star Wars, but he's in a completely different league. There is no one at your level of intimidation, no one with your presence and power, and no one who really challenges you because of that nickname. You can't talk about the Sisters of the Night without mentioning their best-known assassin, the failed Jedi Asajj Ventress. Her sharp features, cold eyes and an even colder presence make Ventress a force to be reckoned with for anyone who dares to cross their path.
Armed with two blood-red lightsabers and divided between the roots of the Little Night Sister and her new fellow bounty hunters, the Ventress calculator truly becomes a kind of fear all its own. Inspired by Sherlock Holmes and legendary military strategists such as Alexander the Great, Grand Admiral Thrawn is the first character on this list to originate from books related to the subject. He also has the distinction of being the first major villain of the post-Return of the Jedi era. The “Thrawn” trilogy of the 1990s remains the most famous book of all, as it rejuvenated the franchise and introduced this tactical genius.
While there is some debate among fans about whether Kylo Ren should continue to be considered a true villain after The Rise of Skywalker, his appearance in The Force Awakens is our favorite, and there he is firmly involved in the field of the bad guys. From the intimidating crossed lightsaber to his chaotic nature, which makes the audience feel that even he doesn't quite know what he's going to do next, Ren's vivid characterization and volatile personality (not to mention Adam Driver's performance) helped make The Force Awakens a worthy successor to the original trilogy. The story of Boba Fett is almost as long as Star Wars itself, which premiered in 1978, and has since been a fan favorite, living many other lives on the page beyond the movies. He worked for the Empire, joined other bounty hunters and even became the leader of the Mandalorian people.
With his return to the Disney canon, he has a whole new future full of adventures that fans are looking forward to, such as The Book of Boba Fett. That mentality clashes with that of the Jedi in one of the most dramatic confrontations of The Clone War, in which Maul reveals that he knows that the Empire is coming and that the Jedi arrive too late to stop him. This unreliable man is the greatest assassin in Star Wars and he is also possibly the scariest character in Star Wars. As an ISB agent, he differs from most of the villains in Star Wars by not being, first and foremost, a warrior with the Force.
Presented as the acrobatic and terrifying antagonist in the first and second seasons of the Clone Wars miniseries, she confronts Anakin Skywalker several times during the galactic conflict. But we especially recommend that you check out his first on-screen appearance in Genndy Tartakovsky's Clone Wars microseries. Boba Fett began his career in Star Wars as a mysterious cartoon character in The Star Wars Holiday Special and as a faceless villain in The Empire Strikes Back and The Return of the Jedi, before making the leap to classic Legends books and comics. General Grievous, who stands above his mechanical henchmen, with a skull-like mask on his face and a presence similar to that of a gigantic arthropod, has sown fear in the hearts of his enemies since he sided with the separatists during the Clone War.
Despite his silent film debut, Bossk proves to be a wild card and a threat time and time again, especially when he teamed up with Boba Fett and his union during the Clone War. Calculating and sinister, calm in their power and total in their control over the boys of the Brothers of the Night, the coven of warriors and witches led by Mother Talzin offers a dreadful vision to anyone foolish enough to betray them. Star Wars is a story about good triumphing over evil, heroes overcome all the challenges that come their way and defeat villains. While many non-humanoid Star Wars characters still have what we would consider humanity, Jabba completely lacks empathy or morality.
Thrawn, the epitome of working smarter, not harder, is a wise thinker who can guess what a culture's war strategy will look like based solely on its art. While Grievous' personality isn't really what attracts here (he has a brief backstory and a tendency for the dramatic), you can see part of his story in the excellent episode of The Clone Wars, “Lair of Grievous”. From the first part of A New Hope to the end of Rogue One and beyond, Vader's intimidating face is synonymous with Star Wars. .
