The Best 2000s Cartoons to Watch Right Now

Ben 10: 

• When Did It Air? December 27, 2005 to April 15, 2008
• Why You Should Watch Now: There have been a wide variety of Ben 10 shows over the course of its lifetime, and each generation of the show has its own fans. But it's hard to deny the impact of the original iteration of the series as Ben 10 remains one of the most iconic action franchises to ever air on Cartoon Network. To this day, fans would still likely want to see a reboot of some sort so you should find out why. 
• Where to Watch: You can check out Ben 10 now streaming on Max, Hulu, and Netflix.

Danny Phantom

• When Did It Air? April 3, 2004 to August 24, 2007
• Why You Should Watch Now: Danny Phantom is another one of those action shows that fans still fondly remember to this day. Although the end of the series didn't quite meet expectations, it's part of why fans are anxious to continue the series in some form to this day. A high school hero story with a jam of an opening theme stood out from Nickelodeon's other hits, so it's hard to beat this ghostly endeavor. 
• Where to Watch: You can check out Danny Phantom now streaming on Paramount+. 

Kim Possible

• When Did It Air? June 7, 2002 to September 7, 2007
• Why You Should Watch Now: Disney has its fair share of notable animated series, but you'd be hard pressed to have more of a fulfilling experience than with Kim Possible. An animated series that felt like it grew up with its audience with each new season and movie, Kim Possible followed the secret spy cheerleader as she balanced homework with big spy missions. Also it's another show with a banger of an opening. 
• Where to Watch: You can check out Kim Possible now streaming on Disney+. 

Invader Zim

• When Did It Air? March 30, 2001 to December 10, 2002
• Why You Should Watch Now: The 2000s were also a very experimental time, and Invader Zim kicked off the decade in style. One of the creepiest, coolest, and off-kilter animated shows to ever air on Nickelodeon, Invader Zim really made its mark with fans and continues to do so all these years later. It's why it even had a movie comeback on Netflix not long ago, and why there's likely still a market for it so long after its first run. 
• Where to Watch: You can check out Invader Zim now streaming on Paramount+. 

Avatar: The Last Airbender

• When Did It Air? February 21, 2005 to July 19, 2008
• Why You Should Watch Now: Avatar: The Last Airbender is experiencing a massive comeback with not only new animated series and movies in the works, but a new live-action series with Netflix as well. That means now is the perfect time to go back an experience the original series that has since spawned a full sequel, multiple spin-off stories, and even more projects to come in the near future. It launched a whole world basically and still holds up strong after all these years. 
• Where to Watch: You can check out Avatar: The Last Airbender now streaming on Paramount+ and Netflix.
