The 2000s are a decade that people originally weren’t supposed to see. At the turn of the century, it was thought all the world’s computers were going to crash due to the infamous Y2K bug. Instead, the decade introduced us to trends that defined the new millennium: frost-tipped hair, plain white t-shirts, and innovative cartoon shows.
The aughts, as fans have come to know them, would usher in a new era in cartoons. While theLooney Tunesand other animated shows were still popular with kids, the 2000 cartoons would open the door for more adult humor to make its way into the animated universe.The best cartoons from the 2000s can often inspire nostalgia with their simplicity and iconic characters that represent a long-gone era.

12’Danny Phantom' (2003 - 2007)
Creator: Butch Hartman
Some regardDanny Phantomas one of the lastgreat cartoons Nickelodeon produced, and with good reason.It’s a stellar entry among the early 2000s cartoons, coming fromButch Hartman(the guy behindThe Fairly Odd Parents) that mixes humor and action well for a pre-teen audience.
The show follows Daniel “Danny” Fenton (David Kaufman), a teen who accidentally turns himself into a half-ghost, becoming the titular superhero, “Danny Phantom.” If there is one criticism of this show, it’s that it had too short of a run, lasting for just three seasons.

Creator: Scott M. Gimple
For a long time, this Disney cartoon was largely forgotten; but hardcore fans rememberFillmore. The series follows Cornelius Fillmore (Orlando Brown), a 12-year-old who joins the safety patrol after being “arrested” for stealing a shipment of chalk.
A parody of the police procedural dramas of the ’70s,Fillmorehad a great voice cast and premise that kept both young and older audiences engaged with its plot.It truly was a shame that it only lasted 26 episodes, and the show could use a movie to give the show the ending it truly deserved.

This hilarious Cartoon Network show had a very wacky premise.A dimwitted boy, Billy (Richard Steven Horvitz), and a cynical girl, Mandy (Grey DeLisle), “befriend” the Grim Reaper (Greg Eagles) by beating him in a limbo contest and putting him in eternal servitude.
First premiering as a segment on theGrim & Evil Show,The Grim Adventures of Billy & Mandyfound its audience and paved its path as one of the network’s best cartoons of the decade. Thougha largely forgotten 2000s cartoon– except for hardcore fans – it’s worth going back to check out what this show was an animated masterpiece of dark comedy.

6’Star Wars: Clone Wars' (2003 - 2005)
Developer: Genndy Tartakovsky
Today, it’s common to seeStar Warsshows on streaming services, but in the early 2000s, there was one series that truly bridged the gap of the latest Star Wars universe:Star Wars: Clone Wars.

5’Teen Titans' (2003 - 2006)
Creator: Glen Murakami
Thanks to its endless reruns on Cartoon Network, it seems thatTeen Titans Go!is the more mainstream adaptation of DC Comics' crime-fighting group. However, its predecessor is often hailed as the superior cartoon.
Debuting on Cartoon Network in 2003,Teen Titanswas a successful adaptation of the comic book series and was one of the more popular shows on the network for its five seasons. The series came to an end in 2006 and was subsequently rebooted asTeen Titans Go. The new series was more oriented towards a kiddie audience, much to the grumbling of fans of the original series.

4’Invader Zim' (2001 - 2006)
Creator: Jhonen Vasquez
The premise ofInvader Zimwas this: a little alien named Zim (Richard Steven Horvitz) wanted to show how big and bad he was by conquering the Earth, only for numerous obstacles to get in his way of achieving his ultimate goal.
While that may seem light on the surface, this Nickelodeon cartoon was deeper and darker than what its premise hinted at. The animation was top-notch, and the series had that perfect mixture of comedy, action, and sci-fi, with some horror elements thrown in there to keep the older crowd entertained. While the premise was quirky and silly,Invader Zim’s shockingly dark episodespresented several storylines that constantly pushed the boundaries of its absurd nature.

3’Samurai Jack' (2001 - 2017)
Creator: Genndy Tartakovsky
Words cannot express how visually beautifulSamurai Jackwas. Premiering on the Cartoon Network in 2001,Samurai Jackwas a principal showcase of just how innovative the showrunners at the network were in creating original content. The masterpiece follows a samurai prince (Phil LaMarr) who gets flung into the far future by the evil demon Aku (Mako) where he reigns supreme.
Called “Jack” by the denizens of the future, this nickname becomes the adopted name of the prince, andSamurai Jack fights to overcomeobstacles to defeat Aku once and for all. After its initial run,Samurai Jackgot a revival in 2017 that wrapped up its sweeping storyline. Once it was done, it was a sad farewell to a beautifully animated show that carved out its legacy.
