Top 10 Cartoon Protagonists that Went Downhill

Cartoon Protagonists/ main characters that went downhill over time. I'll only be including cartoon protagonists for this list. Not side characters or antagonists. Like always if I missed one feel free to add it.

The Top Ten

1 Timmy Turner - Fairly Odd Parents Timmy Turner - Fairly Odd Parents 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.

The whole show is basically dead and Timmy is an ungrateful brat. I'm Actually glad that Butch Hartman left nickelodeon. This show needs to get cancelled - YoshiApple

He's the biggest example of a protagonist that went downhill. He went from naive but caring whenever he screwed up to a downright annoying brat. - SomePersonYouHate

I'm glad I stopped watching. After watching this as a kid, I can't bear to see him today! It's a disgrace. One of Butch's creations ruined. - EliHbk

2 Brian Griffin - Family Guy 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.

He is not really a bad character but sometimes he can be a huge smart alec. - YoshiApple

Brian went from the voice of reason to a overly political douchebag and hypocrite. - SomePersonYouHate

I disagree because his political views are mostly good and he's the open mind in this wirld. He added quite a bit of depth to the series while still remaining funny. That he sometimes acts completely out of character is solely for humorous effect and not canon.

But then, the German market is a few years behind, and furthermore, I am a few years behind the current episode in Germany. Maybe in the meantime he became horrible. - Martin_Canine

It's not his views I have a problem with but the fact that he forces his views onto other people in the show and the audience of Family Guy in general. - SomePersonYouHate

3 Peter Griffin - Family Guy Peter Griffin - Family Guy Peter Griffin is the main protagonist and titular character of the American animated sitcom Family Guy.

He went from being a good father to being an idiot. Don't believe me watch the newer episodes. He beats up random people for no actual reason and tortures his kids ( Especially Meg ) He really deserves to be in jail. - YoshiApple

He has always been an idiot. He has actually done dumber things in the beginning seasons. I do hate how he has changed though. - CameronBinder

He went from a lovable idiot that enjoys his family to a downright jackass enough said. - SomePersonYouHate

4 Cosmo - Fairly Odd Parents Cosmo - Fairly Odd Parents

Similar to Brian at one point he was a voice of reason character but overtime he just gradually became more of a dumbass. - SomePersonYouHate

True but in the older seasons his stupidity didn't nearly kill Timmy... - SomePersonYouHate

5 Wanda - The Fairly Oddparents Wanda - The Fairly Oddparents

Again another voice of reason character that just became a downright naggy bitch as the series progressed. - SomePersonYouHate

6 Lois Griffin - Family Guy Lois Griffin - Family Guy Lois Patrice Griffin is one of the main characters of the American animated television series Family Guy.

She went from a caring mother to a annoying bitch pretty fast. - SomePersonYouHate

7 Sensei Wu - Lego Ninjago Sensei Wu - Lego Ninjago

He went form a wise old man to a annoying pain in the ass. - SomePersonYouHate

He's still decent in my opinion, just underused - darthvadern

8 Zane - Lego Ninjago Zane - Lego Ninjago

Lots of the characters in Ninjago went downhill pretty easily. - SomePersonYouHate

Bringing him back in Season 4 was unnecesary and only to make money, he also acted way more robot in the later seasons which was awful because he was suppose to be a smart robot who acts human! - darthvadern

9 Stan Smith - American Dad Stan Smith - American Dad Stanford Leonard "Stan" Smith is the main protagonist of the adult animated sitcom American Dad!. He is voiced by the series' co-creator and executive producer, Seth MacFarlane.

He never was a good protagonist but in the latest seasons he kind of rivals Peter Griffin. - SomePersonYouHate

10 Patrick Star - Spongebob Squarepants Patrick Star - Spongebob Squarepants Patrick Star is a fictional character in the American animated television series SpongeBob SquarePants. He is voiced by actor Bill Fagerbakke, who also voices numerous other characters on the show . Created and designed by marine biologist and cartoonist Stephen Hillenburg, the series creator, Patrick more.

Okay, Patrick has gotten better as of season 10, but seasons 6-9 Patrick was awful. - Drawbox

The Contenders

11 Francine Smith - American dad Francine Smith - American dad

Like Stan she was never a great character but... she's pretty horrible in the latest seasons. - SomePersonYouHate

12 Jay Walker - Ninjago

Went from a funny comic relief to an annoying gamer - darthvadern

13 Peppa Pig - Peppa Pig Peppa Pig - Peppa Pig
