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 Cartoon Protagonists that Went Downhill

1 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

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 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

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

3 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

4 Cosmo - Fairly Odd Parents Cosmo is Timmy fairy godfather. He's Wanda's husband and Poof's dad. Cosmo is very immature and stupid, but also very charming and a loving father, godfather and husband.
5 Wanda - The Fairly Oddparents


6 Lois Griffin - Family Guy Lois Patrice Griffin is one of the main characters of the American animated television series Family Guy.
7 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.

Patrick Star used to be a really funny and likable character, but now in the modern SpongeBob episodes, he is a complete idiot (in a not good way at all whatsoever) - UltraLunalaX

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

8 Zane - Lego Ninjago

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 Sensei Wu - Lego Ninjago

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

10 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.
