Obnoxious Characters Who Ruined Your Favorite TV Shows

If there's anything that television execs have taught us, it's that there's definitely too much of a good thing. Sometimes, it's in the form of a marathon that runs just a bit too long. This is forgivable and most people won't give the show the side-eye after this.

Many once-beloved shows were canceled after TV execs and writers added one overdone character too many. In some cases, the "too much" was an original member of the cast that got too much airtime or evolved into a terrible but "lovable" person before our eyes.

Chances are, you can rattle off at least one or two obnoxious characters who ruined your favorite TV shows. It's okay. It happens to everyone's favorite shows, and most are canceled shortly after producers realize fans soured on what they created.

As a TV maniac, this is one of the biggest pet peeves out there. Speaking as someone who's seen this happen to way too many shows, I'd like to call the worst offenders out in the list below...

The Great Gazoo, 'The Flintstones'

It's hard to fully understand what possessed producers to write in a space alien character on a show about cavemen. We are going to have to assume that they may have been under the influence of magical 1950s liquor and cigarettes.

Regardless of why they added him in, the fact is that it's really hard to like this character. He's pompous as they come, and honestly, doesn't really do anything with his Gazoo powers. He had all these epic powers, and yet never left for home or did anything to help caveman civilization turn into a more advanced society.

It's safe to say he's probably expelled from his home planet due to egregious crimes involving being a pompous douche. I mean, why else would he stay on earth and talk to a potato-shaped caveman and his next door neighbor?

Snarf from 'Thundercats'

Snarf, oh you bugger. We really don't understand this cat-lizard. He seems to have Tourette's that makes him say, "Schnarf, scharrrrf!" Oh god, and his voice! His voice is so aggravatingly abrasive, it's as smooth as sandpaper.

He always is whining to Lion-O about something. He's clumsy. He doesn't really contribute anything to the Thundercat crew, and is often the laziest one on board. Maybe he was supposed to be a mascot, but producers should have figured out that it wasn't working out.

Rather than write him off, they doubled down on Snarf and involved his "long lost nephew" Snarfer on the show.

Ted Mosby from 'How I Met Your Mother'

Ted Mosby is one of those kinds of self-centered jerks that can't shut up. He spends nine darned years talking about how he met the mother of his children, all the while narrating all the sex he's had as well as "the Sandwich."

Along with checking off all the worst things you can do when you like a girl in the real world, Mosby is the picture-perfect example of a Mr. Wrong. Oh, and you gotta feel bad for his kids. Nothing is quite as cringey as hearing about your parents' sex lives, we're sure.

Ted Mosby is one of those characters who ruined your favorite TV shows only after you think about his actions. Let's face it, on TV, his behavior may seem funny-ish. If you had a guy like Mosby around you on a daily basis, you'd probably be tempted to knock his lights out.

If you think about it, his likability is around that of certain Game of Thrones characters. That's not a compliment.

Andrea from 'The Walking Dead'

Andrea was so unpopular, when she died in Season 3, fans literally rejoiced. This lady was not only totally useless in the zombie apocalypse, but she was genuinely a burden. In the comic book series, she wasn't that bad. On the TV show, though, Andrea made that one hypocritical lady from church look like an angel.

Stopping the action so that she could offer moralizing speeches, keeping a slightly "holier than thou" vibe about her, and just dropping a lot of the suspense of the show made fans hate her.

Very few of the characters who ruined your favorite TV shows have as much hate as Andrea. Ask any Walking Dead fan, and they'll tell you at least 10 reasons they hate this character's guts.

Hey, producers! A good rule of thumb is that people tend to like characters that are closest to the comic book versions. Stick to the script, will ya?

Jerry from 'Tom and Jerry'

Tom and Jerry is a classic TV show for kids, and most kids friggin' adore Jerry Mouse. However, I truly believe that liking Jerry is something that fades with age. If you really look back at how he treated Tom, he quickly turns into one of the worst characters who ruined your favorite TV shows from your childhood.

Jerry eggs Tom on into chasing him, and when Tom isn't hanging out with him, he gets ticked off. He ruined Tom's chances with girls and regularly would play painful pranks on the cat "just because."

With a friend like Jerry, who needs enemies?

Grandmaster B from 'Married...With Children'

Married...With Children is one of the best sitcoms of the 80s and had the unique talent of making almost any viewer feel just a little bit better about themselves.

Al Bundy was incredibly morose in a funny way, living his life as a shoe salesman while living next door to two yuppies. Peggy Bundy was the undersexed housewife who always looked great. Kelly Bundy was the oversexed airhead. Bud Bundy's charm was the fact that he failed so badly with girls.

And then, there was Grandmaster B—Bud Bundy's alter-ego. Grandmaster B was the cringiest, most awkward creation TV writers made in the 80s. Grandmaster B dressed in terrible clothing, rapped like Vanilla Ice, and kept folding his arms like a teenager trying to be edgy.

The worst part was that Grandmaster B was actually played by David Faustino, who was at the time, trying to get into rap. Thankfully, Grandmaster B flopped with the ladies and quickly became a blip in the show's history.

To be fair, he wasn't a Debbie Downer or really that bad. He was just a kid trying to be popular. Even so, not many characters who ruined your favorite TV shows were ever so cringey like Grandmaster B.

Brian from 'Family Guy'

When Family Guy first came out, Brian was the voice of reason who had a little bit of an intellectual streak to him. We liked that Brian—a lot, actually. He was cool, and would have been an amazing dog to hang out with.

Then, when Family Guy rebooted, Brian slowly morphed into a faux intellectual who would do anything to get laid and/or drunk. Quagmire rightfully called him out for being fake, selfish, and narcissistic in that one episode.

I mean, shit, you know it's bad when the show even points out how bad a character is. That was the whole point of Quagmire's tirade about Brian; they really wanted it to sink in how much he sucks.

Family Guy has changed quite a bit. Sadly, with what they did to Brian, we can't honestly say it was a good change in the least bit. If you hate pseudo-intellectuals, you'll understand why Brian Griffin definitely ranks high among characters who ruined your favorite TV shows.

Scrappy Doo from 'Scooby Doo'

This was a dead giveaway. He's the mascot of awful characters who ruined your favorite TV shows. Scooby Doo was never really a paragon of great character development, but then again, it was the 70s and most cartoons just were for quick laughs.

Scrappy Doo was the way that aging executives tried to make the show more relevant to younger kids, and boy did it fail. A bad voice actor, a lot of "look before you leap" moments that almost got him killed, and a stupid catchphrase made him one of the most hated cartoon characters of all time.

To give you an idea of how hated and misguided his character was, Scrappy was actually lampooned on The Simpsons by the invention of Poochie for the cartoon-in-a-cartoon, Itchy and Scratchy.

Goku from 'Dragon Ball'

Dragon Ball is all about fighting and stuff, and Dragon Ball Super still remains quite action-packed. People tend to love the fact that he is such a good fighter and is able to save the world so many times using Super Sayian powers.

During most of the fandom's existence, it was Goku's wife, Chi-Chi, who was considered one of the characters who ruined your favorite TV shows dealing with the Dragon Ball franchise. She was always irritable and constantly argued with Goku.

If you think about it, though, Goku was actually the worse of the two. He's one of the worst anime dads in history because he's constantly running off fighting monsters. Sometimes, he just tells the kid, "Welp, I'm gonna be dead for a bit. Later!"

Piccolo ended up being the one to raise his kid, because Goku was never there. That just is awful, isn't it? Meanwhile, Goku's just out and about doing Dragon Ball stuff, because fuck his family.

Goku's totally unaffectionate to his loved ones, too. It comes out that he's never even kissed Chi-Chi despite being married to her—and even fellow Sayians give him a "WTF" look because of that.

This dude makes no effort to be there for his family, show affection, or even have some kind of accountability. No wonder Chi-Chi was a mess!

Cousin Oliver from 'The Brady Bunch'

It's hard to talk about characters who ruined your favorite TV shows without mentioning the "Cousin Oliver Debacle." Cousin Oliver was one of the first characters to be added into a live-action TV show in an effort to boost ratings and get more views.

It didn't work. In fact, they chose one of the least likable kids we've ever seen. He was a socially awkward, whiny kid that got such terrible reviews, executives took a good look at what happened to the viewership of The Brady Bunch.

Within six episodes of his appearance, they canceled the show for good.

Randy from 'That 70s Show'

That 70s Show had a major problem that Happy Days also faced: the departure of a main character's actor. Unlike Happy Days, which focused on the Fonz living with Richie Cunningham's parents, That 70s Show decided to fix things by adding in a new character—Randy.

Yes, Randy tops the charts as far as obnoxious characters who ruined your favorite TV shows. Everything that people loved about Eric Foreman was erased in Randy. He was thecool kid who just got all the chicks for no apparent reason, had no flaws, and everyone liked just because.

Randy was not only a Mary Sue, he was a really, really obnoxious Mary Sue. Damn right, he was smug about it. This removed any sort of likability he could have had. This series folded after he appeared on it, and Randy almost annihilated its legacy as a result.

That says something, doesn't it?
