17. Sid (Toy Story)

Sid (Toy Story)

It’s hard to imagine a more unlikely candidate for a list of the scariest cartoon characters of all time than Sid from Toy Story. But looks can be deceiving; in Sid’s case, that adage holds.

Sid is the epitome of a bully. He’s big, he’s mean, and he loves to pick on those who are weaker than him. He takes great joy in torturing his toys and seems to derive even more pleasure from watching them suffer.

What makes Sid truly scary is his complete lack of empathy. He doesn’t seem to understand (or care) how his actions affect others and takes sadistic glee in causing pain.

Thankfully, Sid gets his comeuppance in the end (spoiler alert!), but that doesn’t make him any less terrifying. If anything, it just shows that even the most innocuous-looking characters can harbor some severe darkness inside.

Maleficent (Sleeping Beauty)

Maleficent, the wicked fairy from Disney’s 1959 animated classic Sleeping Beauty, is a prime example of a beautifully crafted and terrifying villain.

With her black-and-white hair, skeletal frame, and piercing red eyes, Cruella is as visually intimidating as she is ruthless in her pursuit of the titular Dalmatian puppies.

Cruella’s obsession with fur, specifically her desire to create a coat made from the skins of 101 Dalmatian puppies, drives her evil actions throughout the film. Her lack of empathy and willingness to harm innocent animals for her gain has made her a symbol of cruelty, greed, and vanity in popular culture.

The character’s unhinged behavior, twisted fashion sense, and menacing demeanor make her a standout among cartoon villains.

While Koh is initially only interested in stealing faces, he eventually becomes more interested in causing pain and suffering. He takes great pleasure in torturing his victims, both physically and emotionally.

What makes Koh so scary is not just his appearance but also his lack of empathy. He is utterly unconcerned with the well-being of others and will do whatever it takes to get what he wants. This makes him a very dangerous opponent, both physically and spiritually.

The character’s distorted facial features and unpredictable behavior make her an unsettling presence in the series. Candy Wife’s interactions with other characters, particularly Flapjack, often take on a sinister tone, leaving viewers questioning her true intentions.

Still, Darla disregards his warning and shakes the bag violently, causing Nemo to be knocked unconscious. Darla’s father scolds her for being careless, but Darla doesn’t seem to understand what she did wrong.

The next time we see Darla is at the dentist’s office again, where she captures Nemo again. This time, however, she puts Nemo into a regular fish bowl with no lid instead of a bag.

She accidentally drops him onto the floor as she carries him out of the office, causing him to crack open his egg and hatch prematurely.

Hama is a very powerful water bender but also quite mysterious and enigmatic. She was one of the few members of her tribe who the Fire Nation did not take prisoner during their invasion. Instead, she managed to escape and went into hiding. However, she was captured and taken to a prison, where she was kept for years.

While in prison, Hama developed a new type of waterbending called “bloodletting.” This technique involves manipulating the water within a person’s body, allowing the user to control their movements. It is a dangerous and controversial bending form, and Hama is the only known practitioner of the technique in the show.

Despite her dark abilities, Hama is a complex and tragic character. She has suffered greatly at the hands of the Fire Nation and has been driven to extremes to survive. Her story serves as a reminder of the horrors of war and the toll it can take on those caught in the middle.
