At first glance, Digimon might seem like a simple Pokemon rip-off. It stands on its own amongst 2000s cartoons, however, with a unique premise that was perfect for the new millennium.
A group of friends gets transported into another world inside of a computer, the Digital World. There, they are bonded with one Digimon who they can talk to and command in battle.
During times of extreme crisis, of which there are many, the monsters can Digivolve into superior creatures for a brief amount of time.

Timmy Turner, a well-meaning but ultimately hapless 10-year old boy, is magically granted two fairy godparents who can grant his every wish.

This hilarious show follows the kooky members of Dethklok, a Scandinavian heavy metal band.

While kids of the 2000s figured it was just one of many cool cartoons, today new interpretations view it as kid-friendly commentary on how transgender people must often live a double life, wearing masks around people who won’t understand them.
The list of great cartoons from the 2000s could stretch on for miles—this decade brought young audiences some truly special gems, most of which are just as enjoyable in adulthood. Many cartoons that didn’t make this particular list are still out there. Toons from the best sci-fi anime to episodes of Bob’s Burgers to The Simpsons, and even toons from the 90s that stretch into the 2000s. Many are worth the time for a first-time watch for a new adventure or rewatch just for nostalgia’s sake.
