We all know that cartoon shows and animated feature films produced across the globe are mainly directed toward the younger audience.

However, many of them carry storylines and themes that are a lot more mature than most people would expect.

As a result, some of these spectacular projects are filled with characters that make the kids feel uneasy and, sometimes, downright creepy.

And, since they happen to be so terrifying and vicious, they turn out to be that much more impressive to their viewers.

Given that fans of horror enjoy intellectual stimulation and imaginative activities, watching scary characters and their terrifying antics unfold on-screen offers them a chance to push their boundaries.

Not only do they get to have a ton of fun watching such characters but they also get to learn the limits of their fear. Over time, it helps these sensation seekers learn how to respond when they’re scared out of their wits.

That being said, we’ve jogged our memory to fetch you a piece on 50 of the most terrifying characters from classic animated films and cartoon shows that have gone on to embed themselves into your malleable minds over the years.

1. Orcs and Nazgûl (The Lord of the Rings)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (2)

In Ralph Bakshi’s 1978 animated adaptation of Lord of the Rings, which was made using live-action footage, Tolkien’s monsters are truly the stuff of nightmares.

When Orcs and Nazgûl appear on the screen, they come off as black holes in a cartoon landscape and also probably repulsive intruders from some different realm altogether.

While the Orcs were the primary soldiers of the Dark Lords’ armies and their most common servants, the Nazgûl were also the dreaded ring-servants of the Dark Lord Sauron in Middle-earth throughout the Second and Third Ages.

The Nazgûl are a distinct set created by the nine rings of power that were handed over as gifts to nine human kings. The rings not only gave them power but also ended up corrupting them morally.

Also, yes, an Orc can’t be a Nazgûl no matter how hard they try.

2. General Woundwort (Watership Down)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (3)

General Woundwort is the main antagonist of the book Watership Down, the film, television series, and all other screen adaptations of the same title.

The Chief Rabbit of Efrafa is a thuggish, shrewd, and utterly insensitive tyrant who sees himself as the one doing everything he can for the best of his warren.

He is a brutal and tyrannical leader who is larger and more muscular than most rabbits in his vicinity.

Add to that the fact that he has razor-sharp claws and cold eyes. After having grown into a fully developed rabbit, Woundwort ensured to swiftly usurp leadership, killing the chief rabbit and a rival named Fiorin.

Be that as it may, it is tough not to admire his strong mind and fearlessness. Add to that the fact that he takes greater risks than most rabbits that are seen quarrelling with him.

However, it is surprising to notice that doesn’t give two hoots about nonviolent solutions to problems.

3. Judge Doom (Who Framed Roger Rabbit)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (4)

Judge Doom from Who Framed Roger Rabbit goes on to prove that just because a film features a ton of cartoon characters, doesn’t necessarily mean that it is kid-friendly.

This noir parody is set in a world where one can find human beings and animated characters uneasily coexisting.

And, while the premise may sound exciting, no kid who has seen the film has ever been able to forget the sad*stic Judge Doom.

Doom is revealed to be a cartoon character himself wearing fake skin. He has demonically bulging eyes and a shrill voice.

It is not surprising then that his death proves to be as gruesome as his character sketch is.

Perhaps his most defining trait is that he harbours nothing but hatred in his heart towards Toons.

Also, if you have seen the movie, you’d know that the much-feared man is the ultimate mastermind behind the framing of the titular character and the gruesome murder of Eddie Valiant’s brother.

4. Him (The Powerpuff Girls)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (5)

Even though He from The Powerpuff Girls ceases to look threatening, voice actor Tom Kane and Cartoon Network’s more than capable sound designers put their talent to use and made him as cinematically creepy as possible at the time.

Not only does his lazy voice sound like the very essence of immorality but it also gives an implicit glimpse into the madness and evil lurking beneath his skin.

Having said that, He has an advantage over other antagonists on our list solely because of his usage of physiological torture and manipulation to get the better of his enemies.

Indeed, he is the devil himself and is, therefore, so horribly vile that one even fears to take his real name. As the story proceeds, we see him creating psychological events and taking numerous satanic forms.

Needless to say, his supernatural manifestation of pure evil is startling, to say the least.

And, if that doesn’t make him the personification of evil, we don’t know what will!

5. Judge Claude Frollo (The Hunchback of Notre Dame)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (6)

The main antagonist from The Hunchback of Notre Dame is a powerful Parisian justice minister, who is most likely to remind you of the several real-life dictators to have walked the face of the earth.

Aside from his political authority, Frollo is a religious fanatic who has no tolerance or mercy in his heart for those who may have sinned.

For whatever reason, he believes that Romani people are the most heinous of all malefactors. So, he decides to dedicate years of his life trying to eradicate them.

He does remind you of a certain someone from the rich history of the human world, doesn’t he?

Needless to mention, Frollo’s self-imposed and twisted mission drives him to conduct inhumane acts of violence; all while he tries to use his loyalty and devotion toward God as justification for his many crimes.

6. The Horned King (The Black Cauldron)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (7)

Make way for the main antagonist of Disney’s 1985 animated feature film The Black Cauldron, whose ultimate goal was to find the Black Cauldron and use its power to set loose an army of undead warriors called the Cauldron Born.

The Horned King had a vast army of thugs and monsters at his disposal. He had a skull-like face and an emancipated body wrapped in a long cloak; each of which made him come off as frightening.

This feared ruler of a derelict castle within the swamps in the mythical land of Prydain perhaps managed to appeal to viewers because he had horns.

The fact that he possessed a cold demeanor only gave a definitive edge to his overall personality. What is worth mentioning about The Horned King is the fact that he only showed his anger when his plans failed to materialize.

7. Jenner and Dragon (The Secret of NIMH)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (8)

Jenner and Dragon are the scare-inducing antagonists from The Secret of NIMH.

The former is an evil, intelligent, and quick-tempered creature who can be seen in the Council of The Rats of NIMH quarreling against the Plan.

He does this to emphasize that his ideas are far more useful than that of the other members of the Council.

Dragon, on the other hand, has a small but vital role to play as the secondary antagonist in the film.

Even though he’s an old cat, his name does full justice to his persona. Not only is he responsible for killing Mrs. Brisby’s husband but he is also equally mean.

Dragon can first be seen making an appearance in the scene where Mrs. Brisby meets Jeremy the Crow.

8. Hexxus (FernGully: The Last Rainforest)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (9)

Voiced ably by Tim Curry, Hexxus is an evil spirit who is the chief antagonist of FernGully: The Last Rainforest.

He is shown to be imprisoned in a tree by the fairies of the FernGully rainforest. One day, when lumberjacks start cutting down the trees, they end up putting off the fairies, as well as releasing the horrifying Hexxus.

Hexxus can’t be destroyed but he can be imprisoned. We soon catch him assuming the form of pollution.

Props to the creators of FernGully: The Last Rainforest for deliberately using terrifying images of ecological disasters and demonstrating them as villains.

9. Professor Ratigan (The Great Mouse Detective)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (10)

The early 1980s saw Disney trying to appeal to older children with the release of several darker and more mature animated feature films; one of which was The Great Mouse Detective.

An archenemy of Basil of Baker Street, this suave crime lord was obsessed with his status as a mouse.

However, he lost his cool and revealed his violent and savage mind when labeled a rat.

What makes Professor Ratigan vicious and dangerous is the fact that he is a monstrous thug hiding under a veneer of civility.

Often regarded as the most infamous criminal in all of Mousedom, his impressive track record has provided him with a reputation for being the “world’s greatest criminal mind”.

10. Grigori Rasputin (Anastasia)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (11)

The main antagonist of the animated musical epic Anastasia, Grigori Rasputin was pretty much a cartoon villain brought to life by his makers.

Not only was he an evil megalomaniac sorcerer but he was also a cruel priest and wicked Cossack Soldier. Add to that the fact that he referred to himself as the “most mystical man in all Russia”.

Even though Rasputin was shown to be killed early in the motion picture, his body survived courtesy of his dark magical powers. However, we did see it falling apart in the most gruesome manner with the passage of time.

The character was also seen placing a dreadful curse on a Russian imperial family, the members of which perished in the Russian Revolution.

Credit has to be given to director and producer Don Bluth for turning him into a villain in their brilliant cinematic endeavor.

11. Chernabog (Fantasia)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (12)

This dark deity from Slavic mythology makes an appearance in the final segment of the 1940 animated film Fantasia.

He is in the form of a colossal demonic being who seems to be looming over the lesser evil spirits.

The undisputed ruler of a dark realm called Bald Mountain, Chernabog only strives to amuse and appease himself. He can also be seen summoning demons and damned souls to sacrifice and do bidding on his behalf.

One of the most powerful and destructive villains to have ever been created by Walt Disney, he’s been depicted as a ruthless and manipulative monster who can scare anyone who encounters him out of their bloody wits!

Props to the makers for introducing this menacing character with a villainous background score and fierce, glowing eyes.

12. Lawrence Limburger (Biker Mice From Mars)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (13)

Lawrence Limburger is the main antagonist from the popular Saturday morning cartoon series Biker Mice From Mars, which originally aired in syndication during the mid-1990s.

Don’t mistake the show’s villain Lawrence Limburger for coming across as a corporate mogul who seems to be dressed in a purple pinstripe suit.

This is because he is an alien from Plutark who can be seen peeling off his human skin from time to time to reveal the evil (a bloated fish-like figure) lurking beneath.

Also the arch-nemesis of the Biker Mice, he first came to planet earth under the disguise of a human.

Soon after, Limburger was seen posing as an opportunistic industrialist who operated out of the city of Chicago.

13. Mumm-Ra (ThunderCats)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (14)

The most unsettling thing about Mumm-Ra is that he simply cannot be killed.

Pale and draped in a tattered cloak, he is known to put his magical powers on display whenever he gets an opportunity to.

Moreover, he can be seen using the Mutants of Plun-Darr as pawns in his schemes to topple the ThunderCats.

Voiced efficiently by Earl Hammond, Mumm-Ra apparently originates from within the Black Pyramid among the ruins of an ancient civilization.

Needless to say, his introduction is pretty scary for a Saturday morning cartoon villain. However, you must know that this character only calls upon the Ancient Spirits of Evil to grant him the shape of Mumm-Ra when he is fuming in anger.

Also, his appearance does make him come across as a zombie on steroids. Even though it’s silly, his creators have been able to pull it off rather convincingly.

14. Venom (Spider-Man)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (15)

How many of you know that the character of Venom emanated from an idea by an ardent fan of the Spider-Man franchise who wished to give Peter Parker an advanced costume with cooler colors?

Soon enough, Marvel purchased the idea and propelled comic book illustrator Mike Zeck to develop it. All thanks to Venom now, the viewers have an opinion about what an alien-human hybrid may look like.

Venom possesses sharp and animalistic teeth with a lower jaw that he can unhinge like a snake. It made its first TV appearance in the 1994 Spider-Man cartoon where it was voiced by Hank Azaria.

While its facial structure was already scary, its Hulk-sized body was also prominent enough to give the young fans some good old-fashioned scare.

15. Sid (Toy Story)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (16)

If you ever think of a person you wouldn’t wish to hang out with, Sid is probably the lad who’ll resemble that name on all counts.

He is a bully who mutilates his toys and loves to cause destruction and terror. Not only that but we are also introduced to his dark bedroom that is full of misfit toys that he has apparently destroyed over time.

Needless to mention, keeping things that he has damaged makes him come across as a creep of sorts.

Many would argue that he is sociopath who is mostly seen wearing a black t-shirt that has a skull on it. And, yep, the guy is a reminiscent of most bullies out there in the real world as well.

16. Henry J. Waternoose III (Monsters, Inc.)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (17)

The main antagonist of Pixar’s fourth full-length animated feature film Monsters, Inc., Henry J. Waternoose III is the CEO of Monsters, Inc and someone whose reputation precedes him.

His bad intentions are often matched by his creepy appearance: beady eyes and crab legs. Henry, who only cares about the success of his company, does his best to assist Randall in his evil plot; something that eventually leads to his downfall.

Even though a lot many of you would be of the opinion that Randall is the scariest character in the film, Waternoose is definitely right up there as well.

The boss and grandfather-figure-turned-archenemy of James P. Sullivan and Mike Wazowski were voiced by the late James Coburn.

17. Yzma (The Emperor’s New Groove)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (18)

Since Yzma from The Emperor’s New Groove has a dark and scary aesthetic side to her, she portrays the chic villain role with pride and panache.

Not only does she love to exert her power by coming across as merciless but she can also be seen coming up with some incredibly devious techniques to get rid of Kuzco.

Needless to say, this allows us to peek into her dark and untrustworthy mind. To take revenge on her foster son who fired her as his advisor, the hideous old woman goes to the extent of planning to usurp the throne by murdering him.

Also, let’s not forget that the diabolical and street-smart Yzma has a strong but rather dimwitted henchman named Kronk.

18. The Evil Queen (Snow White and the Seven Dwarfs)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (19)

The Evil Queen, also known as the ‘Wicked Queen’, gives us the ultimate creeps as it is. However, when she revamps into an old hag with the aim to incite the princess with an apple, that’s when we truly get a glimpse of her dark potential and determination.

Since her voice, movements, and motives continue to come off as unnerving, it wouldn’t be an exaggeration to assert that she is the original evil witch and an inspiration to several such wicked screen characters for years to come.

The Queen’s deadly obsession with wanting to remain the prettiest of all makes her despise the innocent Snow White, who is arguably the only one whose beauty surpasses everyone else’s.

19. The Beldam (Coraline)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (20)

Also known as ‘The Other Mother’, The Beldam is notorious for camouflaging her victims’ mothers. She is the main villain of Neil Gaiman’s dark fantasy young adult novel Coraline, which was later adapted into a full-length animated feature film of the same title.

If the character sporting buttons for eyes isn’t horrifying enough for you, make peace with the fact that she can also turn into a horrifying and bloodthirsty spider.

While Coraline has got to be among the creepiest animated movies of all time, The Beldam is also one of the creepiest animated characters out there.

This seemingly perfect mom has the unmatched ability to transform into a sinister monster within seconds. Watch out!

20. Scar (The Lion King)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (21)

No one likes Scar from The Lion King and we can’t blame them for despising the character. The dark-at-heart and foreboding lion, who was next in line to assume the throne as king of the Pride Lands, was utterly jealous of Simba.

This compelled him to come up with a plot to take over the kingdom by hook or by crook.

While watching the beloved animated feature, one felt that this easy-to-hate character only wished to watch the world burn.

One of Disney’s most infamous villains, Scar rose to prominence after having devised a successful plan to murder Mufasa.

21. Koh the Face Stealer (Avatar: The Last Airbender)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (22)

A major recurring villain in the Avatar series, Koh is one of the most powerful and knowledgeable spirits in the Spirit World.

The malevolent entity with the body of an enormous centipede-like creature can steal the faces of other living beings who make the mistake of expressing any form of emotion in his presence.

As a result, his appearance often seems to be different, ranging from that of animals to human beings. Born to the Mother of Faces thousands of years before the Hundred Year War, Koh prefers to live under a tree in the Spirit World.

22. Cruella De Vil (101 Dalmatians)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (23)

The chief antagonist of Disney’s 101 Dalmatians, the eccentric Cruella De Vil has got to be among the most popular scary characters to make it to our story.

The fashion-obsessed heiress, who is also known as a ‘witch’ and ‘devil woman’, is obsessed with furs; so much so that it drives her to murderous insanity.

Not only does she wish to use the skins of 99 Dalmatian puppies to create a spotted fur coat but she also resorts to kidnapping and slaughtering to satisfy her mania.

One can usually find Cruella De Vil being aided by her henchmen Jasper and Horace.

23. Hades (Hercules)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (24)

The antagonist of Disney’s animated feature film Hercules is the fast-talking god of the Underworld, who is not exactly approachable.

This is because he’s a bit of a loose cannon who literally has flames for hair. Needless to say, Hades just comes across as someone you wouldn’t want to ever cross paths with in your life.

Even though he may have fooled you with his sense of humor, do not make the mistake of underestimating his unpredictable temper and cruel intentions.

We say so because he has only been scheming to take over Mount Olympus and the cosmos for close to two decades.

24. Oogie Boogie (The Nightmare Before Christmas)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (25)

Keeping all of Oogie Boogie’s shenanigans in The Nightmare Before Christmas aside, let’s first face the fact that he is a sack filled with bugs.

If the aforementioned fact wasn’t enough to stir you, we must all agree that any character who has the heart and audacity to abduct our beloved Santa Claus must be harboring some truly dark intentions.

The infamous Boogeyman is both feared and despised for his ghastly disposition and cannibalistic appetite. He lives on the outskirts of Halloween Town. His henchmen are Lock, Shock, and Barrel.

25. Hopper (A Bug’s Life)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (26)

Yes, we do agree with you that all bugs are creepy. However, when it comes to Hopper, we get to see a different face of bugs altogether.

This malicious and self-serving character, aside from being the villain in A Bug’s Life, is also the leader of the grasshoppers and Flik’s arch-nemesis.

We cannot even imagine what your reaction would be if you get to see the downright evil Hopper in the corner of your room in the middle of the night.

Well, all we’d like to say is that please leave the room silently before this ruthless and belligerent character is given the space to make a move.

26. Maleficent (Sleeping Beauty)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (27)

An incarnation of pure evil, the scare-inducing Maleficent from Sleeping Beauty is responsible for all the misfortune in King Stefan’s kingdom. She is the archetype of what a villain should be.

After having taken offense at not being invited to the christening of Princess Aurora by Stefan and Queen Leah, Maleficent ends up cursing the princess to die; an act that shows the very darkness of her heart.

The animated classic is known to have gotten unnerving for young viewers back in the day who were startled by the action sequences between royalty and magical creatures.

27. Darla Sherman (Finding Nemo)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (28)

What is perhaps the scariest part about some of these animated characters is that a few of them do not appear to be spooky at all. And, that is precisely where their strength comes from.

Darla from Finding Nemo is one such character. She might look like a harmless little girl from a distance, but there is more to her than what meets the eye.

While her smile can give you the creeps, the fact that she shakes a living creature in a bag until it dies with no remorse whatsoever speaks volumes about her sociopathic nature.

28. Candy Wife (The Marvelous Misadventures of Flapjack)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (29)

A significant supporting character in The Marvelous Misadventures of Flapjack, Candy Wife is Peppermint Larry’s wife who is made up of candy; thereofre, explaining her name.

Even though she has been referred to as “inanimate” by other characters in the series, one can often catch her moving and ominously peeking around the corner.

In the show, which makes the audience laugh and then resorts to terrifying them, Candy Wife stands out as a particularly curious and creepy character to watch out for.

29. Hama (Avatar: The Last Airbender)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (30)

A waterbending master from the Southern Water Tribe in the popular series Avatar: The Last Airbender, Hama seemed to be the last one to be captured and imprisoned by the Fire Nation during the Southern Water Tribe raids.

However, she managed to escape through the use of the bloodbending technique. Also known as ‘The Puppetmaster’ or ‘The Witch’, she plays a minor but crucial role in the series.

Even though she is not traditionally scary, Hama is a ruthless Waterbender who went on to develop the taboo practice of Bloodbending after having been kidnapped by the Fire Nation.

This was done with the sole purpose of exacting her revenge on the Fire Nation and anyone else who dared to stand in her way.

30. Randall Boggs (Monsters, Inc.)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (31)

One of the two main antagonists of the animated feature film Monsters, Inc., Randall Boggs is a snide and vindictive character that seems to be quite envious of James P. Sullivan, who’s the most beloved “scarer” in Monstropolis.

Even though he came across as a kind and timid teenage monster while in Monsters University, he turned into a ruthless and temperamental creature in Monsters, Inc.

In order to steal the spotlight from Sullivan and make his presence felt in the world, Randall starts abducting human children; all while ceasing to care about people and their feelings.

31. The Coachman (Pinocchio)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (32)

The third antagonist of Disney’s animated feature film Pinocchio, The Coachman is a sinister figure who is infamous for luring “stupid little boys” to Pleasure Island.

There, he gets them to transform into donkeys to be sold on the black market. Needless to say, this malevolent and extremely dangerous being has no redeeming qualities whatsoever.

He takes pleasure in his wicked actions that have gone on to destroy the lives of many children. What is worth noting about him is that he seems to target disobedient and selfish boys who can be seen indulging in trouble for the sake of unabashed merriment.

32. Lady Tremaine (Cinderella)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (33)

Unlike other Disney movies, Cinderella isn’t full of elements of horror but certainly does contain that scary X factor when it comes to the stepmother Lady Tremaine.

Lady Tremaine certainly plays her part of the ‘evil stepmother’ exceedingly well. Yes, she is known to have been horrible to Cinderella over the years.

Not only does she force her to cook and clean but she is also seen not allowing her a moment of calm.

Right from the moment she makes her remarkable appearance, one pretty much understands that fear seemsnto have found a new face in Lady Tremaine.

And, whenever there is a close-up shot of her face, we know that something truly horrible is going to happen.

33. The Lich (Adventure Time)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (34)

The main antagonist of Adventure Time is an ancient cosmic being who is a plain and blunt manifestation of the inevitable death of all things.

It is implied that his essence was deposited on Earth millions of years before the beginning of the show via a catalyst comet.

The fact that death is one of the oldest fears of mankind makes this character scary enough to comprehend.

However, the mere thought that there exists an immortal being with superpowers that can allow him to kill every living being out there is a potent enough reason to include this character on our list.

34. Ursula (The Little Mermaid)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (35)

Ursula is a villainous Cecaelia (half-woman, half-octopus) who is a close-to-perfect personification of the many fake sages in the modern world.

Just like the superficial self-styled godmen today, she can also be seen striking deals with the unfortunate and helpless merfolk with the promise of making many of their lifelong dreams come true.

However, what is even more frightening than her tacky blue eyeshadow is that she carries the ability to scare many of her viewers into believing that she can show up in their bathtub and, subsequently, magic them into one of her poor unfortunate souls.

The character is partially based on the nameless sea witch from the original Hans Christian Andersen tale.

35. Dr. Facilier (The Princess and the Frog)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (36)

Also known as ‘The Shadow Man’, Dr. Facilier is the main villain from Disney’s 49th full-length animated feature film, The Princess and the Frog.

One of Disney’s most renowned antagonists, he is an evil witch doctor/bokor and Lawrence’s new employer, who plans to not only rule New Orleans but also, eventually, the whole wide world.

In his pursuit of the same, he believes that he will receive assistance from his “friends on the other side”.

Voiced by Keith David, he is also Tiana and Naveen’s arch-nemesis and the killer of Ray.

36. Big Boy” Pickles (Rugrats)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (37)

What is scary about this giant baby boy from Rugrats is that he is the imaginary younger brother of Angelica Pickles.

And, since he occurs in her dreams, he can just about do anything to psychologically scar her. Even though his only appearance is in “Angelica’s Worst Nightmare”, his presence is solid enough to make an impression our minds.

Angelica was scared of him not only because he was portrayed as mean but also because he was an unmistakable representation of her fear of not getting enough attention and care due to her baby brother.

That is perhaps why the baby seemed to be getting bigger every single time he appeared on the screen.

37. Rick Sanchez (Rick and Morty)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (38)

Rick and Morty is a television show that has a surprising amount of existential horror injected into its storytelling.

While many of you may not be scared of Rick Sanchez at face value, we have valid reasons to justify his presence here.

First things first, Rick tends to lash out at his loved ones primarily because he’s had serious issues to deal with in the past.

Secondly, since he is a super-scientist, which gives him the brains to do whatever he wishes to with his genius inventions.

Also, his many shenanigans reveal a ton of things about the true nature of the universe.

38. The Nightmare King (Little Nemo: Adventures in Slumberland)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (39)

The antagonist in this cult-classic animated film from the late 1980s is the haunting, amorphic Nightmare King.

While the origins of the tyrannical and authoritative ruler of the dreaded Nightmare Land is not entirely clear, what is known, however, is the fact that he is apparently the embodiment of nightmares.

As we have mentioned, he rules over Nightmare Land, which is a dark world that represents all the fear and darkness of the world’s nightmares.

39. The Red Bull (The Last Unicorn)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (40)

The Last Unicorn is a quality animated fantasy feature film that thrives not only on its memorable soundtrack but also on its exceptional set of voice actors.

However, there is also the dreadful character of Red Bull that stands out in its storytelling. An evil magical creature who appears in the form of a bull covered in fire, he is used by the wicked King Haggard to herd Unicorns into the sea to keep him happy.

40. Freaky Fred (Courage the Cowardly Dog)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (41)

Fred happens to be Muriel’s nephew who first makes an appearance in the episode “Freaky Fred” to visit his aunt.

Even though Muriel seems to be quite fond of him, he is disliked by both Eustace and Courage. While the former even goes to the extent of calling him a “Freak”, the latter is simply just horrified by the sight of him.

Considered to be one of the scariest villains in the beloved series, his creepy posture and his unkempt hair are enough to give you nightmares.

Fred has a deeply unsettling voice and also suffers from trichotemnomania, which is apparently an obsession with shaving people until they’re bald.

41. King Ramses (Courage the Cowardly Dog)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (42)

Even though most of the characters in Courage the Cowardly Dog were frightening, one character that truly managed to make an impression on me was King Ramses.

Ghost of a pharaoh from Ancient Egypt, he makes his appearance in the episode “King Ramses’ Curse”. In order to retrieve an ancient slab that was stolen from his tomb, he ends up bringing about three plagues on the Bagge family.

King Ramses was easy to recognize due to his prominent skull attire; one that was reminiscent of Egyptian burial masks.

42. Frank (Cars)

This combine harvester is known to guard the tractors at night while they are asleep. He can be seen attempting to get Mater and Lightning when he discovers that they are tractor-tipping.

In one of the Cars movies, Tow Mater and Lightning McQueen can be seen flipping over tractors at night in a field.

Enter Frank, a giant harvester who, out of nowhere, can be glimpsed steamrolling over the hill. Yes, the aforementioned sequence was scary enough for this character to make it to our story.

43. The Clown (The Brave Little Toaster)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (44)

The crooked Clown from The Brave Little Toaster, who comes across as a Pennywise-wannabe, is a part of Toaster’s nightmare.

While the character has got absolutely nothing to do with the overall plot of the movie, it does, however, demonstrate that the makers were only looking forward to injecting a scary character into the screenplay, irrespective of what the narrative required.

If you are not creeped out by his devilish grin that rivals that of Bill Skarsgård, you certainly will get goosebumps when he delivers his one word of dialogue with unmatched hatefulness in his heart and tone.

44. Ghostfreak (Ben 10)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (45)

Ghostfreak from Ben 10 is a phantom/ghost-like alien with a gaseous appearance and claw-like hands. Since he has a gaseous appearance, it is next to impossible to catch or control him.

Add to that the fact that he possesses grey skin with black lines running all over it. Also, it is worth mentioning that his removable skin has black and white striped tentacles underneath it.

The Original Series showed the Omnitrix symbol peeking out of the skin on his lower left chest.

45. Toffee of Septarsis (Star vs. the Forces of Evil)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (46)

This immortal Septarian monster from the animated series Star vs. the Forces of Evil is someone that Moon fought when she was young.

Aside from serving as the overarching antagonist in the first season, he also portrayed the main antagonist in the second season and the premiere of the third season, respectively.

The blue-skinned Septarian can be recognized by his slicked-back dark purple hair and yellow eyes. Known for his knack for combining manipulative talent with considerable force of will, he can be seen donning his trademark black suit with a white shirt underneath it, and a red tie.

46. Yellow Diamond (Steven Universe)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (47)

The makers of Steven Universe have done a fine job of developing substantial characters with valid motives that viewers can understand.

However, it is important to understand that, just like in the real world, there are some characters in the show that still make monstrous choices despite having seemingly practical objectives.

Yellow Diamond fits the bill of the aforementioned description. Even though she can be seen grieving the loss of her one-time companion Pink Diamond, she is caught expressing that grief through ceaseless anger; an act that threatens to impact an entire civilization.

47. Bilbo Baggins (The Hobbit)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (48)

While the Hobbits are supposed to be the good guys in J.R.R. Tolkien’s globally renowned The Lord of the Rings trilogy of films, they are a bit fat and froggy in 1977’s The Hobbit.

Hobbit Bilbo Baggins is a small freaky dude with premature wrinkles, who is introduced during the terrifying chase scenes and destructive battles in the story.

This introduction is certainly done to incite existential anxiety among the viewers, and believe us when we say that the makers truly succeed in what they set out to do with Baggins.

Needless to say, the 1977 feature was a children’s special, but it comprised content and characters that were capable enough of even creeping the adults out.

48. Sharptooth (The Land Before Time)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (49)

Sharptooth is a large, male Tyrannosaurus who has enormous teeth. He is the prime antagonist in the original film The Land Before Time.

The name, Sharptooth, which is given to him by other characters in the movie, is basically widely used to refer to the name of his species.

Although many different theropod species have appeared throughout the franchise, it is this huge male Tyrannosaurus that is difficult to forget.

49. Scarab (Young Justice)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (50)

Since Young Justice is set in the DC Universe, it should come as no surprise that it is full of creepy characters.

That said, it is interesting to note that one of the scariest characters happens to be Scarab that goes on to provide the Blue Beetles with their numerous superpowers.

Although the scarab is all about technology, its artificial intelligence has given it a personality and a tremendous amount of power; something that can be truly fear-inducing if used unapologetically.

50. Heffalumps (The Many Adventures of Winnie the Pooh)

Top 50 Most Popular Scariest Cartoon Characters Of All Time (51)

A lot of youngsters today have confessed online that they were terribly scared of the Heffalumps from The Many Adventures of Winnie the Pooh.

Even though the semi-antagonistic elephant-like creatures went on to become allies of Pooh and his pals, they were depicted as figments in Pooh’s nightmares.

The Heffalumps were mostly seen as frightening thieves who often partnered up with woozles to take honey without giving their actions much thought.

The fact that they were elephant-like creatures was a reason strong enough to startle kids at the time.
