We already have a list called "Best Villains of All Time", so I though how about we get to the darker side, shall we?
A "Complete Monster" is plain and simple: They are basically the most evil characters in a series. So its obvious there's gonna be some rules: These villains must not have any redeemable qualities (Personality wise), are always taken seriously and are pretty much hated by everyone. And lastly, a complete monster doesn't necessarily need to be the main villain of the series he/she is in (E.g. Envy from the 2003 Full Metal Alchemist and Quan Chi from the Mortal Kombat series).
There are a lot of irredeemable monsters in several outlets of media, but which one do you think strikes the biggest chord?
1 The Joker
The Joker is a fictional super villain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940) published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, ...read more.
Of course the Joker. How many unforgivable acts has he committed throughout his history (E.g. Killing Jason Todd and The Killing Joke may be the most memorable, but they're just two) is baffling considering he's been around since 1939, but his relationship with the Dark Knight is what makes him really stand out. Oh, and he's a nihilist, so he doesn't give a damn about anything. And lastly, Heath Ledger's performance was really haunting too. - CrimsonShark
2 Emperor Palpatine
Sheev Palpatine (also known by his Sith identity Darth Sidious and publicly as Senator Palpatine, then Supreme Chancellor Palpatine, and later Emperor Palpatine) is a fictional character and one of the primary antagonists of the Star Wars franchise, mainly portrayed by Ian McDiarmid.
Many Sith Lords (With Darth Bane being an exception) tend to show some form of redeemable traits, but Sidious is none of that. He killed his family before "baptizing" himself to the dark side and even killed his master Darth Plagueis to take over his title. He treated Darth Maul badly just to make him a remorseless killer and actually didn't care for Darth Vader either. However, credit must be given to him, for he took his time before destroying the Jedi systematically and taking over the republic, effectively ruling the entire galaxy. - CrimsonShark
Freeza (Pronounced "Frieza" in the Funimation dub) is fictional character in the Dragon Ball series by Akira Toriyama as the primary antagonist of the Freeza Saga. He is a galactic tyrant who governs the Planet Trade Organization and is feared by the universe for his sadistic and brutal nature. He is ...read more.
If anybody was to pick out a villain from the Dragon Ball series, the first is usually going to be Frieza, and why the hell not? He destroys entire races and gloats about it and will do anything to torture anyone he fights against. Its surprising how polite and honest he acts, never hiding his sadistic and megalomaniac personality at all. - CrimsonShark
Big jerk! - EliHbk
4 Kefka Palazzo
Kefka Palazzo is a character in the Final Fantasy series of video games. Originally designed by Yoshitaka Amano, he appears in the 6th installment of the series - Final Fantasy VI.
Kefka's basically the Joker of video games. Except he actually takes things way too far and destroys the world, just to become a god. Oh, and his final battle music is so great :). - CrimsonShark
5 Green Goblin
The Green Goblin is the alias of several fictional supervillains appearing in American comic books published by Marvel Comics, mostly those starring Spider-Man. The character first appeared in The Amazing Spider-Man #14, and since then he has become one of the characters most famous villains. He was ...read more.
Norman Osborn (The first Green Goblin) definitely deserves to be Spider-Man's arch-nemesis (I like Venom too, but the Goblin seems more fit). He killed Gwen Stacy and gloated about it later on and always does his best to make sure Peter's life is as miserable as it gets. He was also responsible for the clone saga and led the Dark Avengers as soon as he took over SHIELD. And lastly, he doesn't care about his son Harry at all. While the kind of guy that everybody would hate upon first meeting him, this reputation makes him one of Marvel's most evil villains and a personal favorite of mine. - CrimsonShark
Lord Voldemort is a fictional character and the central main antagonist in J. K. Rowling's series of Harry Potter novels. Voldemort first appeared in Harry Potter and the Philosopher's Stone, which was released in 1997.
Carnage (Cletus Kassidy) is a fictional supervillain appearing in American comic books published by Marvel Comics, usually as an enemy of Spider-Man. He appeared for the first time in The Amazing Spider-Man #361.
Sauron is the title character and main antagonist of J. R. R. Tolkien's The Lord of the Rings. Originally a servant of the first Dark Lord, Morgoth. Morgoth was later defeated and Sauron fled. He later came back to Middle Earth and took over as the new Dark Lord by using a Ring of Power. He was later ...read more.

11 Michael Myers
Michael Myers is a character from the Halloween series of slasher films. He first appears in John Carpenter's Halloween as a young boy who murders his older sister, then fifteen years later returns home to murder more teenagers. ...read more.
Dr. Loomis's quote about him basically sums up this character's personality. While I do like Freddy Kruegar more (And he's a Complete Monster too), Michael stands out because its his emotionless and sadistic nature that terrifies the audience. - CrimsonShark
Scar is the main antagonist of Disney's 1994 animated feature film, The Lion King. He was the second son of Ahadi and Uru — who were, at one time, King and Queen of the Pride Lands — the younger brother of Mufasa, and the uncle of Simba.
13 Johan Liebert
14 Handsome Jack
Handsome Jack is the main antagonist of both Borderlands 2 and Tales from the Borderlands and the deuteragonist of Borderlands: The Pre-Sequel.
The best video game villain of all time...sorry Vaas. - MetalPope
I love Handsome Jack, he is my favorite borderlands character... but I understand why he's on here! - EliHbk
15 The Batman Who Laughs
16 Claude Frollo
Scar is pretty damn close, but Follo wasn't just the most evil Disney villain, but also a really disturbing and dark one, considering he's the antagonist of an animated kids film :/. - CrimsonShark
Venom, or the Venom Symbiote, is an alias used by several fictional characters appearing in American comic books published by Marvel Comics, commonly in association with Spider-Man.

The best villain in My Little Pony friendship is Magic, he is very intimidating and posed as a serious threat, he's not some Goofy cartoon villain, he is legitimately dangerous.
Flowey is a flower in the RPG Undertale. He is the first character you meet, and also your best friend.
