If ambition had a face, it would probably be J.R. Ewing, the slick oil tycoon from the TV show Dallas . Manipulative, calculating, cold, incredibly greedy, and even treacherous, he checks all the boxes for one of TV’s most hated—and most memorable—villains.

David Schwimmer brought to life one of the most memorable characters in American sitcoms. We’re talking about Ross Geller from Friends , a character who could easily land on both the "most beloved" and "most hated" lists. And that’s the charm of Ross: fans who adore him point to his generosity and intelligence, while those who can’t stand him blame his jealousy and tendency toward constant drama. Which side are you on?

Mr. Burns (The Simpsons)

The millionaire Mr. Burns is the perfect example of a cartoon villain. And maybe it's not just his cold, calculating, and greedy nature that makes him so unlikable, but also his total inability to relate to or understand the problems of ordinary people. While it's hard to truly "hate" any character from The Simpsons , we can safely say he does not exactly inspire affection.

Kimmy Gibbler (Full House)

Kimmy Gibbler, played by Andrea Barber on Full House , is one of those characters who sparks mixed feelings. Some viewers find her loud, quirky, and intrusive behavior charming. However, for others, those same traits can be a bit too irritating. Whether you adore her or can’t stand her, no one could imagine the show without Kimmy.

Janice (Friends)

Those of us who watched Friends need just three words to remember this character: "Oh. My. God!" That’s Janice's trademark line, repeated almost every time she appears on the show. It’s not malice that gets under our skin, but her shrill voice, endless energy, and constant drama. And of course, she won’t leave Chandler alone, who does everything but be upfront about his feelings.

Livia Soprano (The Sopranos)

Livia Soprano, mother of none other than Tony Soprano, manages to make us hate her from the very first season, and that’s part of what makes her such a compelling character. Bitter, cold, distrustful, manipulative, and calculating, Livia helps explain much of the protagonist’s behavior; through her, we glimpse the roots of Tony’s twisted mind.

Pete Campbell (Mad Men)

Arrogant, manipulative, and always chasing status, these traits make Pete Campbell, played by Vincent Kartheiser, one of the least favorite characters on the iconic Mad Men . His hypocrisy and relentless ambition often lead him to overlook ethics and empathy, which is exactly why he earns a spot on this list.

8

Negan (The Walking Dead)

A villain so terrifying that he earns the hatred of viewers definitely deserves a spot on this list. We’re talking about Negan, the ruthless leader played by Jeffrey Dean Morgan on The Walking Dead . His brutality, arrogance, and need to control everything make him one of the show’s most frightening and unforgettable antagonists.

Nellie Bertram (The Office)

Played by the iconic Catherine Tate, Nellie Bertram joins The Office in the finale of the seventh season, and her excessive arrogance and pushy personality quickly make her one of the most irritating characters on the show. However, we have to admit it: on The Office , even the characters who get on our nerves often manage to make us laugh out loud.

10

Connor Roy (Succession)

A mix of wealth, eccentricity, vanity, greed, and a misplaced sense of power make Connor, the eldest Roy sibling in Succession , one of the least favorite characters in the series. His habit of taking advantage of others and expecting rewards he hasn’t earned is one of the key reasons he lands on this list.

Venomous Snakes

You have heard of the rattlesnake , right? There are 16 members of this family of venomous snakes alone in the United States. That is one dangerous family if you ask me. Aside from those, you can also bump into a coral , a cottonmouth , and a copperhead snake, all in the same country, all venomous too.

Unfortunately, snakebite victims often don’t know a snake has bitten them until it is too late. The best strategy is to not get bitten in the first place but, if you are bitten, you should get to an emergency room as soon as possible. Try not to move the bitten limb as this increases blood flow and spreads the venom faster throughout your body.

Black Widow and Recluse Spiders

Lucky for us, out of the 3,000 plus species of spiders that can be found in the United States, only 2 are known to be venomous. Those are the Recluse Spider and the infamous Black Widow .

If not treated in due time, Black Widows and recluse spiders are especially dangerous and even deadly to children, the elderly, and the sick. Luckily, these spiders are mostly rare to encounter. Nonetheless, you should always remain vigilant, particularly when it comes to Black Widows. These dangerous creatures tend to live in closer proximity to humans and their bites are extremely painful and can have long-lasting consequences.

Hornets, Bees, and Wasps

What is worse than a venomous creature? A venomous creature that flies! Hornets, wasps, and bees kill far more Americans each year than any other animal. Understandably, most of these deaths are due to allergies, but this shouldn’t diminish the risk, as the majority of victims likely did not know they were allergic in the first place.

One of the most dangerous species, killer bees , also known as Africanized Bees, attack in swarms, often with devastating results. Upon any detection of a threat to their hive, an individual can be chased for up to a quarter of a mile. Although the venom from an individual sting is not considered to be particularly potent, simultaneous stings can lead to excess swelling, pain, and potential death if the recipient is allergic to bee stings.

Scorpions

One of the most menacing-looking creatures around, the scorpion is an arachnid with a venomous sting. Its weapon of choice is its stinger on the end of its tail, used to inject venom into un-expecting enemies or predators.

Moreover, scorpions are also equipped with pincers, though these cannot cause substantial damage to a human; it is considered to be the case that the smaller the pincers, the stronger the venom, so watch out for miniature claws in the summer. When it comes to particular members of the species, the Arizona Bark Scorpion is the most potent one in the USA and carries a potentially lethal sting.

5

Gila Monster

A creature with an epic name if we ever saw one, the Gila Monster is the only venomous lizard in the United States. And, even though they are venomous, Gila Monsters rely more on their powerful crushing jaws to subdue their prey.

If you happen to find a Gila Monster, observe this dangerous animal from a safe distance.

Though it isn’t fatal, the Gila Monster’s bite is excruciatingly painful. These lizards have small, razor-sharp teeth that dig into the skin and inject their venom. The effects can last for hours or days, depending on how much venom someone is exposed to.

6

Colorado River Toad

A toad with a psychedelic reputation, the Colorado River Toad releases a venom that is illegally harvested and used as a hallucinogenic drug, and it is even classified as a controlled substance.

It is also dangerous to most animals and large dogs who accidentally eat them have been known to be paralyzed or even die from the poison. Never handle this toad with your bare hands, and keep your pets away from them as well.

Ticks

A nasty little creature, the tick is one of the most dangerous animals in the United States. While ticks sometimes live indoors, they’re most commonly found in grassy or wooded areas with water nearby. They wait on tall grasses for a host to pass, then jump onto the living creature and attach to start feeding.

These insects are considered dangerous because they can spread disease when they pierce the skin. Although there isn’t a hard and fast rule, it’s accepted that the longer a tick is attached, the higher the risk of infection. If you notice a tick on your skin, you should remove it with a tick key, wash the area with soap and water, and contact your doctor.

Kissing Bugs

Don’t be fooled by their colorful appearance, there is nothing nice about these insects. Kissing Bugs gets its name from the habit of biting near their victims’ mouths. These insects carry a parasite that causes Chagas disease. Although it’s treatable in its early stages, if an infection is left untreated, it can cause a chronic, lifelong illness.

Initial symptoms of this disease include fever, fatigue, body aches, headache, rash, loss of appetite, diarrhea, and vomiting. One of the easiest ways to prevent Kissing Bug bites is to use mosquito netting and insect repellent while you’re in areas where these insects live. Also, make sure to follow up with a doctor if you notice bites or sores around your mouth and nose.

Common Desert Centipede

Centipedes are one of the strangest-looking insects and many people fear them because of their aspect. The Common Desert Centipede is a pale orangey-brown color with lateral black stripes. It’s best to avoid this centipede in the United States.

The bite of the Common Desert Centipede is one of the most painful bites possible from an arthropod. Much worse than a wasp sting, it has been compared to the Bullet Ant Sting and will almost certainly send you to the emergency room. The venom spreads after the initial bite, and the pain worsens until you seek treatment.

Fire Ants

The name itself is not the most reassuring one. Fire ants are a group of stinging ants made up of over 200 individual species, all of which sting, with varying levels of pain. Additionally, they’re more aggressive than other ant species.

These insects form large colonies and usually eat insects, plants, and flowers. However, if their nests are disturbed, they won’t hesitate to swarm and sting large animals, including humans. Unfortunately, their stings are quite painful and are often compared to the feeling of being burned by an open flame.
