1 Invader ZIM
Invader Zim is an American animated television series created by Jhonen Vasquez for Nickelodeon. The series centers on an extraterrestrial named Zim from the planet Irk, and his mission to conquer Earth and enslave the human race along with his malfunctioning robot servant GIR.
As you'd expect, it had low ratings amongst the target audience. - SpaceGoofsGeekerBoy
I don't understand why people want this show to come back but they didn't even watch it when it was on T.V. cause of low ratings. MAKE UP YOUR MIND PEOPLE - 23windomt

2 Hi Hi Puffy AmiYumi
Hi Hi Puffy AmiYumi is an American-Japanese animated fantasy-comedy television series created by Sam Register for Cartoon Network.
Ben 10 never should've existed. Cartoon Network was better off with this AND the original Teen Titans instead of Ben 10. - RegularShowFTWSuperjailFTL
The series increased Cartoon Network's viewership back in the 2000s. It centered around the animated Puffy AmiYumi, and was inspired by Rocky and Bullwinkle, Hanna-Barbera, old MGM and Warner Bros. cartoons, and UPA cartoons, while maintaining its anime influence. Why was it cancelled? Two reasons.
1. The series, along with Teen Titans (2003) were overshadowed by the popularity of Ben 10 and My Gym Partner's a Monkey.
2. Renegade Animation went on to do the work on the live-action/animated Cartoon Network television movie Re-Animated.
Those were why Sam Register, creator and showrunner of Hi Hi Puffy AmiYumi quit Cartoon Network in 2006. Even when Cartoon Network picked up a 4th season! This show should've lasted until 2009, if it wasn't for Ben 10, My Gym Partner's a Monkey, and Out of Jimmy's Head. - SpaceGoofsGeekerBoy
god dammit ben 10 - hunterthebird
3 Sym-Bionic Titan
Sym-Bionic Titan is an American animated action science fiction television series created by Genndy Tartakovsky, Bryan Andrews, and Paul Rudish for Cartoon Network.
The fact Cartoon Network chose The Problem Solverz over this is very sad. - RadioHead03
I really love this show! It just sickens me that Cartoon Network had to cancel this show in favor of that Problem Solverz show! - RegularShowFTWSuperjailFTL
Created by Paul Rudish, Bryan Andrews, and Dexter's Laboratory and Samurai Jack creator Genndy Tartakovsky, Sym-Bionic Titan was acclaimed for its intense action and writing, as well as big budget animation. Why was it cancelled? It did not have a toy line. So, instead, we got the Problem Solverz to replace its time slot. - SpaceGoofsGeekerBoy
I just love this show.😔 I wish this show back on Cartoon Network.
Chowder is an American animated television series created by C.H. Greenblatt for Cartoon Network. The series follows an aspiring young child named Chowder and his day-to-day adventures as an apprentice in Chef Mung Daal's catering company.
It was cancelled because Cartoon Network thought it was too childish and they wanted more live-action shows. It's a shame, because this is one of my favorite Cartoon Network shows. - Drawbox
Seriously, I liked Chowder which was such a great Cartoon Network show that never should have been cancelled. It would have lasted more longer than that ridiculous Teen Titans Go.
This was sadly cancelled, because it did not fit with Cartoon Network's older boy demographic. - SpaceGoofsGeekerBoy
People only like chowder because of the memes
Catscratch is an American animated television series created by Doug TenNapel (also known for creating Earthworm Jim).

Apparently, Nick felt like it doesn't deserve a proper DVD release (its only episodes released are two of them on the Nick Pick DVDs). - KalloFox34
This came out the same year as Avatar. - kcianciulli
Shame Nickelodeon doesn’t remember this show. - RadioHead03
6 The Modifyers
I know this did not become a T.V. show, but why was it rejected? It was created by Lynne Naylor and Chris Reccardi, whose other credits include Chowder, Ren and Stimpy, the Powerpuff Girls, My Life as a Teenage Robot, Tiny Toon Adventures, Samurai Jack, and Foster's Home for Imaginary Friends. It even stars the talents of Mae Whitman, Paul Rugg, and Jeff Bennett. Why was it rejected? Not only that cliffhanger ending, but it was done in favor of Back at the Barnyard. Or maybe it was that female protagonist, unless the Mighty B! was greenlit.
Nickelodeon must've done a HORRIBLE movie like that. Disney Channel should've picked up the series if Cartoon Network or Nickelodeon won't. - SpaceGoofsGeekerBoy
This should've been greenlit instead of that garbage Mighty B!
Would of been way better than Mighty B. - RadioHead03
I agree! This show SHOULD HAVE been a T.V. show. It’s even more of a shame that Chris Reccardi died. At least Lynne Naylor is still alive. If the Modifyers does become a series, hopefully Charlie Bean would take Chris Reccardi’s position as co-showrunner. - RegularShowFTWSuperjailFTL
7 Teen Titans
Teen Titans is an American animated television series created by Glen Murakami, based on the DC Comics characters of the same name.
I heard there wasn't much merchandise for the show, so they cancelled it. - Drawbox
My sis and I used to watch every episode of this... now it's gone and all what's left is the awful TTG.. - ConeHat
This show should NOT have ended the way it did. - KeyboardHero
Again. Overshadowed by Ben 10. - SpaceGoofsGeekerBoy
8 Korgoth of Barbaria
Created by Aaron Springer, a writer for Dexter's Laboratory, Samurai Jack, SpongeBob SquarePants, and the Grim Adventures of Billy and Mandy, and starring the voices of Diedrich Bader, Tom Kenny, John DiMaggio, Corey Burton, and the late Craig T. Raisner. This series is what happens when you cross Conan the Barbarian with Rick and Morty.
This was even picked up for a series by [adult swim], but was unfortunately rejected due to its high budget. It was later rejected in favor of shows like Superjail! and Xavier: Renegade Angel, which had a LOWER budget. - SpaceGoofsGeekerBoy
9 Earthworm Jim (1995-1996)
Was based off of a video game and is STILL a far better show than Ren & Stimpy - xandermartin98

Madeline is a television series produced by DIC Entertainment, L.P., part of the Madeline media franchise. It began as a series of television specials, and then was continued as various seasons of the TV show.
The Main reason why I'm voting this twice is the fact That At least the Other shows weren't overshadowed by what could possibly be the worst Non-Disney /Junior Cartoon: Quack Pack. Though this show did air on Playhouse Disney, But was also overshadowed by another Mediocre Disney show: Mickey Mouse Clubhouse. Thankfully this show isn't Overshadowed as Much for being on Qubo. You can Watch it Tuesday Nights. - Rainbowkid38
Again another Show That was overshadowed by a Mediocre Show (That show is Quack Pack). - Rainbowkid38
15 Clone High
BEFORE Phil Lord and Chris Miller became overrated as Hell - xandermartin98

Although if you want to talk about staying in its prime,
I'd have to say it actually went on for a bit too LONG - xandermartin98
Was actually ended by decision of its creator, but still easily counts nonetheless - xandermartin98
43 The Fairly OddParents
The Fairly OddParents is an American animated television series created by Butch Hartman for Nickelodeon.
No, this show lasted too LONG.
It should have least been given a proper ending. - kcianciulli
16 years was long enough. And only the first 5 or 6 seasons were any good. - KalloFox34
In my opinion, it was good until they introduced that Mutt and that Mary Sue. I want to see Quagmire do things to Chloe's mom then kill all the Carmichael family. I would be laughing my guts out. - kcianciulli
