We’ll start with comic books’ most nefarious villain. Should an alien visit us tomorrow, it would be very hard to explain that a playing card-themed maniac is an archetypical antagonist to a bat-themed superhero. And yet, ever since appearing in Batman’s very first solo comic book, the Joker has proved again and again why he is known as "the Clown Prince of Crime".

Just like Batman, the Joker doesn’t have any superpowers besides his cunning and wicked sense of humor. Although definitively insane, he is remarkably smart, which is shown by his expertise as a chemist. He is responsible for creating his signature "Joker venom", a chemical compound capable of forcing anyone to smile.

The Green Goblin is to Spiderman what The Joker is to Batman. Another bad guy with a flare for theatricality (though almost all comic-book villains do), this flying menace soars through the air on his "Goblin Glider", his patented flying device.

Contrary to his superhero antagonist, this villain’s backstory is simple and selfish: wealthy industrialist Norman Osborn became this alter-ego to rule organized crime in New York City. Nowadays, Willem Dafoe’s portrayal of the Green Goblin in the 2001 "Spiderman" movie is perhaps this character’s most remembered iteration.

There are many reasons why "Die Hard" is considered the very best action movie in history, from its groundbreaking setting to its amazing dialogue and fast-paced action. However, one of the most influential factors behind this movie’s legacy is Hans Gruber, the sophisticated and soft-spoken nemesis of John McClane.

Wonderfully portrayed by Allan Rickman, Gruber arrives at the fictional Nakatomi Plaza under false pretenses, with the sole purpose of stealing millions in bearer bonds. Rickman's superb performance almost made us feel bad when his plans got foiled by a certain adventurous NYPD detective. An action movie that made us feel bad about its bad guy! Can you imagine that?

Should we add a spoiler warning for one of the most iconic reveals in the history of cinema? We won’t disclose it in the very (extremely) slim chance that you haven’t seen "The Empire Strikes Back". However, we are absolutely sure that you are familiar with science fiction's most memorable villain, even if you haven’t seen a single scene in any "Star Wars" movie.

Truly, Darth Vader needs no introduction: From his menacing mask, cold demeanor, and lightsaber skills, this Sith knight is truly a force to be reckoned with. What’s perhaps most iconic about Vader is his deep and powerful voice, provided by Hollywood legend James Earl Jones.

Granted, the 2003 musical "Wicked" made us realize that Elphaba, also known as "The Wicked Witch of the West", was a truly nuanced character. However, by the time she received her dishonorable title in "The Wizard of Oz", Elphaba had become a dastardly green-skinned witch, hellbent on foiling the plans of Dorothy and her friends.

Margaret Hamilton’s performance in the 1939 version of "The Wizard of Oz" was so iconic that it cemented the look that most media witches would have over time: You can thank Hamilton for the pointy black hats, green make-up, and terrifying cackles you hear every Halloween.

Just like with our Darth Vader entry, we have to ask: Is anyone not aware of the groundbreaking twist in Alfred Hitchcock’s most famous movie? We’ll once again have to tread lightly, but that doesn’t mean we can properly remember Norman Bates, the bone-chilling villain from "Psycho".

Portrayed by Anthony Perkins in the original 1960 movie and its 3 sequels, Norman Bates is the shy, mild-mannered proprietor of the "Bates Hotel", co-owned by Norman and his mother. However, anyone watching this classic thriller for the first time will quickly realize that there’s something sinister hiding in this hotel.

You would expect someone nicknamed "Hannibal the Cannibal" to be a feral brute with an insatiable bloodlust, but Dr. Hannibal Lecter is, above all, well-mannered. While he definitively has the bloodlust part going, Lecter has been described as a soft-spoken, intelligent, and cultured monster since his first appearance in the 1981 horror novel "Red Dragon".

Most of us remember this character from Anthony Hopkins’ character in "Silence of the Lambs" and "Red Dragon", but did you know that there was a previous film portrayal of Hannibal Lecter? Scottish actor Brian Cox portrayed him in the 1981 film "Manhunter", although under the last name "Lecktor".

When posters for the movie "Alien" first appeared in movie theaters, they had a simple yet terrifying tagline: "In space, no one can hear you scream". This 1979 horror masterpiece by Ridley Scott introduced the world to the now-iconic "Xenomorph", the perfect killing machine that haunts outer space.

Part of what makes the Xenomorph so memorable is its groundbreaking design, a huge departure from the traditional aliens depicted up to that point. It helps that they were designed by Swedish artist H.R. Giger, who in turn based them on his own 1976 surrealist painting "Necronom IV".

Who knew that the perfect nemesis for "The Man of Steel" would be a bald billionaire? Lex Luthor is Superman’s lifelong and most-famous nemesis, always plotting to bring the world’s most powerful superhero to his knees.

In a way, the fact that Luthor has no superpowers other than his remarkable intellect is particularly fitting: While heavy-hitters like Doomsday or Metallo can physically hold their own against Superman, Luthor’s human greed and resourcefulness ultimately prove to be the biggest threat to this hero.

We’ll end with the only robotic villain in this article. When audiences first met the artificial intelligence known as HAL 9000 in Stanley Kubrick’s groundbreaking "2001: A Space Odyssey", they were perplexed by how a single red light talking in a monotone yet calm voice could be so downright terrifying.

In truth, that’s part of what makes HAL such an incredible villain: He is not a sadistic, murderous monster, but rather a cold and calculating machine run by logic. HAL chooses to destroy the astronauts aboard the "Discovery One" only because he considers them a threat to the spacecraft’s plans. So, in a sense, this machine was only doing what it was programmed to do.
