Cartoon Characters Who Devolved Terribly Over Time

Characters who started off being likable and good are now annoying and horrible.
The Top Ten
1 Peter Griffin - Family Guy Peter Griffin is the main protagonist and titular character of the American animated sitcom Family Guy.

The reason why Peter is a moron because his parents treat him the wrong way

I saw this video where Peter tries Red bull for the first time. It's messed up.

Peter whent from being just the idiot father to violent psychopath.

I like the show but Peter is annoying

2 Glenn Quagmire - Family Guy Glenn Quagmire, often referred to as just Quagmire, is a character from the animated television series Family Guy.

Honestly Brian deserved everything Quagmire said. Brian used to be the worldy, self educated, voice of reason, w/o much of an overinflated ego. He was talented, soulful, well read, and a patron of the arts and musical theater. His only flaw was his alcoholism. Now he's the poster child of overly opinionated, super liberal, hipster.

Quagmire was the wrong person to give the rant on brian. as quagmire has the same flaws and admits them, but brian tries to make up, overcome and get rid off them, that is why brian is not honest about them. quagmire is just jealous brian is a better person than he is. he used to be funny, but he is too flawed himself to point someone else flaws out.

He started off funny at first, but he's been flanderized to the point of being a creepy sex maniac.

He use to be funny now I can't stand him, he's a total A hole to Brian.

3 Robin - Teen Titans Go Robin, is a fictional superhero appearing in American comic books published by DC Comics, commonly in association with the superhero Batman.

Robin was not bratty before this terrible cartoon started, I liked Robin better in the original version

It's obvious he plans to make Cartoon Network be in his filthy baby hands!

Don't put the original character's picture here it is to good for Teen Titans Go! version.

The WHOLE show sucks, not only the characters...

4 Ned Flanders - The Simpsons Nedward Flanders Jr. is a recurring fictional character in the animated television series The Simpsons.

The idea of a character devolving to their more obnoxious traits is named after him for a reason.

5 SpongeBob SquarePants - SpongeBob SquarePants SpongeBob SquarePants is a fictional character and the titular character and protagonist of the American animated television series of the same name.

SpongeBob started out being a naive sand lovable main character, whom many people adored and liked. But ever since the movie he became EXTREMELY annoying, Tom Kenny must have gone reverse puberty or something because his voice is so darn squeaky nowadays! It's not even just his voice change, it's just the fact his character went from cute and childlike, to loud and obnoxious. Just look and see, I'm 99% sure Nick keeps him on because of the money he rakes in.

Once he was a 13 year old teenager who worked his ass off. He had clutch. He was a bit slow to react, but in the end, he was smart, and no matter what the job, always got the job done, without the use of tears. As the show went on, he slowly transformed into a more dumber man child with no self control, and cries as a last resort. He even starts to use tears as a method of figuring stuff out.

ALL the characters of this show have become more stupid, mean, and overly exaggerated than they already were. All the qualities that made them so likable are just falling apart. SpongeBob cries at EVERYTHING, Patrick turned into a prick, Squidward isn't that egotistical anymore and is just trying to survive his torture porns, Mr. Krabs fina

He's back to his original self. The original creator came back last year. And the episodes are actually pretty funny

6 Lisa Simpson - The Simpsons Lisa Marie Simpson is a fictional character in the animated television series The Simpsons. She is the middle child and most intelligent of the Simpson family.

I use to like Lisa but after a few season she's become a preachy know it all.

She went from just a little girl who happens to be smart for her age to an outright Tumblrina

7 Winslow T. Oddfellow - CatDog

He used to be funny. Than he just started harrasing and bullying Cat.

He just ruined the show.

8 Squidward Tentacles - SpongeBob SquarePants Squidward Tentacles is a fictional character voiced by actor Rodger Bumpass in the American animated television series SpongeBob SquarePants.

I kind of feel sorry for squidward because of SpongeBob and patrick always bugging througout the series but sometimes he can be very aroggant, concieted and ruthless towards others.

I think I'm squidward...

9 Timmy Turner - The Fairly Oddparents Timothy "Timmy" Tiberius Turner is a ten-year old boy who is a fictional character and the main protagonist of the American animated series The Fairly OddParents created by Butch Hartman for Nickelodeon.

Timmy did get dumber as the seasons went on, but I personally believe that is not where he completely devolved at.

Timmy used to be a kid with a heart and a caring person in general, he made mistakes and was often impulsive with his actions. But he always apologized sincerely and redeemed his sometimes selfish or bad decisions in the end. He sacrificed himself for his family, friends, and even enemies multiple times and would always be there for them, and he was an easy to sympathize with character. Episodes like Channel Chasers and Abracatasrophe show what I am talking about.

Nowadays Timmy is a selfish, spoiled brat who only cares about himself. He never considers the feelings of others and has no redeeming qualities whatsoever anymore. He's not really stupid, but just a huge jerk. I prefer Pre-Poof Timmy.

I remember back when Timmy was a decent character. He used to be nice and always learn from his mistakes, but over the years (to be exact, when the show started to go downhill), he suddenly became an irresponsible, selfish, annoying, rude, and idiotic butt hole! He honestly makes Cosmo look like the genius!

Another problem with Timmy in modern Fairly Odd Parents is that he's always, and I mean ALWAYS, learns the same lesson again and again and again and again. I mean, how many times has this kid caused destruction due to his wishes? Don't you think he would've learned how to be careful with what he wishes for by now? On top of that, he even has the nerve to treat his fairies like garbage sometimes! Why did he deserve them again? It's not a kid who doesn't know better but has good intentions, it's a selfish, stupid kid who never even thinks about the consequences, and is never given any consequences!

On a small note, his voice doesn't help either. To me, Tara Strong does ...more

I agree, Timmy used to be irresponsible and selfish, but had some level of common sense. He's now almost as dumb as Cosmo from the early seasons.

Timmy has gotten more selfish and careless over the years. In fact, he has lost all likability right to the point where he shouldn't have fairies anymore.

10 Marge Simpson - The Simpsons Marjorie Jacqueline "Marge" Simpson is a fictional character in the American animated sitcom The Simpsons and part of the eponymous family. She is the wife of Homer and the mother of three children in the family.

I swear if she ever does that huge gasp or shriek "NOO! " when Bart or Lisa do something they enjoy, I'm gonna sue Matt Groening!

The Contenders
11 Lil DeVille - Rugrats and All Grown Up Lillian Marie Jillian DeVille is a main character in both the Rugrats TV series and its spin off series All Grown Up!. Lil is Phil's older twin sister and the daughter of Howard and Betty. She is voiced by Kath Soucie.
12 Eric Cartman - South Park Eric Theodore Cartman, often referred to just by his surname, is a main character, as well as a major antagonist and occasional antihero in the animated television series South Park, created by Matt Stone and Trey Parker, and voiced by Parker. He is one of four central characters in South Park, along with Stan Marsh, Kyle Broflovski, and Kenny McCormick. Cartman first appeared, originally in prototypical... read more

I don't really think he counts as someone who's devolved over the years. I mean, he was a jerk back then and he's still a jerk now. I do still find him funny too.

Eric just seriously got less funny, like cheating to get in the Special Olympics?

He harm Kyle, Kenny, Stan, and the love interest to Stan named Wendy.

13 Poof - The Fairly OddParents

Don't put Poof here. Besides, Sparky and Chloe Carmichael are WAY worse In my opinion.

Lol your list says went worse over time.I see just a list of worse characters getting more worse.

I hate this character he has no personality

14 Mrs Turner - The Fairly OddParents
15 Mr. Krabs - SpongeBob Squarepants Eugene H. Krabs, or simply Mr. Krabs, is a fictional character in the American animated television series SpongeBob SquarePants.

He went from being a penny-pinching cheapskate who actually cared for his employees to a greedy money-grubber who only cares about himself.

Season 1- Cared for people was nice liked money. Now Only cares for himself loves money and is horrible to people. I miss 1999- 2006 Mr Krabs.

Before, I liked him better than Plankton. Now I realize that Mr. Krabs is nothing but an ass to Plankton.

Mr. Krabs was always cheap and not the greatest guy around, but now he is just a jerk.

16 The Overlord - Lego Ninjago
17 Meg Griffin - Family Guy Megan "Meg" Griffin is a character from the animated television series Family Guy, voiced initially by Lacey Chabert, thereafter by Mila Kunis.

Meg used to be that quiet but nice girl who really tried to fit in and make friends. Now she's a bitter, self-mutilating teen with stalkerish tendencys, and weird bedroom habits.

18 Patrick Star - SpongeBob SquarePants Patrick Star is a fictional character in the American animated television series SpongeBob SquarePants, and he is one of the 10 main characters in the show. He is voiced by actor Bill Fagerbakke, who also voices numerous other characters on the show. Created and designed by marine biologist and cartoonist ...read more.

He used to be comic gold, but now he's become a prick. He often botches up people's plans for no good reason i.e. getting SpongeBob stuck in that wringer, popping up out of nowhere to eat the backstage passes and disappear, etc.

While most of the time our favourite star keeps it humourous, there are a few episodes like Stuck In The Wringer and Yours, Mine and Mine where things start to slip.

Used to be more silly than stupid, but he did have those occasions and an overall low IQ. But now he is utterly brain-dead to the point where it just isn't funny/.

He used to be the dumb but usually smart lovable guy in the beginning, now he's so stupid that it's painful to sit through.

19 Mordecai - Regular Show Mordecai is one of the two main protagonists of Regular Show, along with his best friend Rigby. He made his debut in the non-canon short "2 in the AM PM" as a human cashier, who then morphs into a prototype Mordecai-like character with a fanny pack. He later makes his first official appearance in the Pilot episode. Mordecai is voiced by the show's creator, J.G. Quintel.
20 George - An Egg's Guide to Minecraft
21 Bart Simpson - The Simpsons Bartholomew JoJo "Bart" Simpson is the oldest child, and the only son, in the 1987 show The Simpsons. He was created by Matt Groening. His hobbies are pranking people including Lisa Simpson and Homer Simpson.
22 Chloe Carmichael - Fairly Odd Parents
23 Phil and Lil's Mom - Rugrats and All Grown Up

In All Grown Up she became really old and started saying really stupid things. She called Kimi a parrot for no reason.

24 Brian Griffin - Family Guy Brian H. Griffin, popularly known without his middle initial as Brian Griffin, is a fictional character from the animated television series Family Guy.

Seasons 1-5-Voice Of Reason Whose High Intelligence Helped Peter Get Through His Problems.

Seasons 6-7-Okay

Seasons 8-Present-Librel Uncaring Douchebag Who Only Cares About Himself And Dating Prostitutes

Seriously? only 33? this guy is the dictionary definition of character decline. I loved this guy in the first three seasons. Then he just... died. Man I miss old brian.

Liberal atheist
