When given the freedom to do so, cartoonists can be very creative with character designs. This has led to a number of strange-looking and unusual personalities across the medium, whether it be a heroic piece of toast, a man with an alien living inside his giant head, or a creature that holds its eyeballs in its hands.

It's not just the appearance of a cartoon character that can make them strange, though. A particular voice can turn a regular-looking creature into something else entirely. The personality of the character can also be what makes them odd. They could look like a normal person, but their interests and mannerisms could be completely off the wall.

Mischievous but with a heart of gold, Cow is Chicken's 7-year-old, 600-lb younger sister. Of all the characters in the cartoon, Cow is the most outlandish, in large part because of her voice.

She's voiced by Charlie Adler, who also voices Chicken, Red Guy, and I. R. Baboon in the show, but Cow's voice is so shrill and nasally that it's the most eccentric and weird. Cow has an alter-ego, Supercow, who can fly, has super strength, and is practically invincible.

When he gets a call from Washington, Powdered Toast Man's toast particles disintegrate.

CatDog, as the name implies, is an animal that is half cat, half dog. The feline/canine's very existence raises anatomically related questions. For example, how and where does it go to the bathroom? It can also be an issue when figuring out which direction to go in. The two may share a body but their personalities couldn't be more different, with Cat being sullen and miserly and Dog being naive and goofy.

4 Him's Presence Is Unsettling, Especially For A Children's Show (The Powerpuff Girls)

HIM maniacally laughs Powerpuff Girls

Him, the devil-like villain from The Powerpuff Girls, is a weird and unsettling character, particularly for a kids' show. His evil laugh, incongruous schemes, and otherworldly voice that can change on a dime make him an ominous and unpredictable foe. Him's mind was so sinister and twisted that he once decided to give everyone candy because the idea of torturing people by giving them cavities was more enjoyable to him than outright destroying them.

It features Jim, a trade school student whose head grows to outlandish proportions. In the first episode, it was revealed that Jim was out walking late at night when he saw flashing lights in the sky, and then he was suddenly in bed with a giant head.
