The 12 Best Nickelodeon Cartoons of the 2000s

The 2000s marked a golden era for Nickelodeon animation, a decade when the network evolved from its 90s roots into a powerhouse of inventive storytelling, boundary-pushing humour, and visually striking worlds. From the sprawling epic adventures of bending masters to the absurd undersea antics of a porous sea sponge, these cartoons captured the imaginations of a generation while laying the groundwork for modern animated television. They balanced kid-friendly fun with clever writing that appealed to adults, often sneaking in social commentary, surreal gags, and emotional depth.

Ranking the best involves weighing factors like cultural impact, innovation in animation and narrative, memorable characters, critical acclaim, and enduring popularity through reruns, merchandise, and reboots. We prioritised shows that premiered or peaked in the 2000s (2000–2009), focusing on those that defined Nickelodeon’s output with originality and replay value. Excluded are 90s holdovers unless their 2000s runs elevated them anew. This list celebrates 12 standouts, countdown-style from solid gems to absolute masterpieces.

What made the 2000s special? Technological leaps in digital animation allowed bolder styles, while creators like Jhonen Vasquez and Butch Hartman brought punk edge and magical whimsy. These series influenced everything from DreamWorks epics to Adult Swim oddities, proving Nickelodeon could rival Disney in ambition.

  1. Tak and the Power of Juju (2007–2009)

    Emerging late in the decade, Tak and the Power of Juju adapted a PlayStation 2 game into a vibrant cartoon blending tribal mysticism with slapstick comedy. Created by Kevin McDonald and others, it follows the bumbling shaman-in-training Tak as he navigates a colourful Polynesian-inspired world filled with quirky spirits, Lok and Jibolba, his shaman mentors. The show’s strength lies in its exotic art style—rich hues, fluid animation, and exaggerated character designs that popped on early HD TVs.

    Voice acting shines, with McDonald voicing Tak in his signature manic style, adding chaotic energy to episodes like “The Ultimate Hugfest,” where magical mishaps ensue. Though short-lived at two seasons, it earned praise for cultural fusion and humour that didn’t talk down to kids.[1] Its legacy endures in gaming tie-ins, representing Nickelodeon’s push into interactive media. Ranked here for its underrated charm and visual flair amid flashier peers.

  2. El Tigre: The Adventures of Manny Rivera (2007–2008)

    Sandra Equihua and Jorge R. Gutierrez’s El Tigre burst onto screens with a hyper-stylised Mexican wrestling aesthetic, following Manny Rivera, a teen torn between heroism and villainy thanks to his dual-heritage powers. Premiering alongside Tak, its bold cel-shaded animation and Latin-inspired flair set it apart, influencing later works like Gutierrez’s The Book of Life.

    The series excels in moral ambiguity, with Manny’s flips between El Tigre (villain side) and good-guy instincts driving hilarious conflicts with his cop father and supervillain mum. Episodes like “Adios Amigos” showcase explosive action and family dynamics. Critically lauded for diversity, it faced cancellation due to ratings but gained cult status online.[2] A perfect entry-level pick for its energy and foresight.

  3. My Life as a Teenage Robot (2003–2009)

    Robo-comedy peaked with Rob Renzetti’s My Life as a Teenage Robot, centring on XJ-9 (Jenny), a super-powered android navigating high school crushes, bullies, and alien invasions. Its sleek, angular design and elastic physics delivered kinetic action sequences rare in girls-led shows.

    Jenny’s fish-out-of-water struggles—wanting fun amid world-saving duties—resonate with tween angst, voiced brilliantly by Janice Kawaye. Standouts include “Attack of the Monster Squid,” blending teen drama with over-the-top fights. Four seasons cemented its feminist undertones and humour, earning Emmys and inspiring robot tropes in media.[3] Essential for its empowering vibe.

  4. Teenage Mutant Ninja Turtles (2003–2009)

    The 2003 TMNT reboot by 4Kids Entertainment revitalised the franchise with darker tones, intricate fights, and anime influences. Brothers Leonardo, Raphael, Donatello, and Michelangelo battle Shredder’s Foot Clan in a grittier New York, blending martial arts mastery with brotherly banter.

    Superior animation from Dong Woo Animation featured dynamic choreography, elevating episodes like “The Ultimate Ninja” into mini-epics. Voice cast, including Michael Sinterniklaas, added gravitas. Running seven seasons, it won multiple awards and bridged to the 2007 film, proving reboots could surpass originals.[4] A powerhouse of action and lore.

  5. Jimmy Neutron: Boy Genius (2002–2006)

    John A. Davis’s Jimmy Neutron spun a 2001 movie into TV gold, following hyper-inventor Jimmy and pals Carl and Sheen on sci-fi escapades in Retroville. CGI-hybrid animation innovated for Nick, with shiny gadgets and expressive faces.

    The show’s wit sparkles in brain-bending plots like “The Trouble with Clones,” satirising mad science. Voices by Debi Derryberry and Jeff Garcia nailed youthful exuberance. Three seasons plus the film grossed acclaim for smarts and heart, influencing Phineas and Ferb.[5] Timeless for geeky charm.

  6. The Fairly OddParents (2001–2017)

    Butch Hartman’s magical mayhem defined long-form Nick animation, with miserable Timmy Turner wielding fairy godparents Cosmo and Wanda’s wishes gone awry. Absurd premises and rapid-fire gags filled ten 2000s seasons.

    Susie Carmichael’s addition deepened dynamics, while Daran Norris’s versatile voicing shone. Episodes like “Channel Chasers” parodied TV tropes brilliantly. Massive merch empire and Emmys underscore its dominance, blending nostalgia with sharp satire.[6] Unmissable endurance test.

  7. Hey Arnold! (1996–2004)

    Craig Bartlett’s urban poetry peaked in its 2000s finale, chronicling football-headed Arnold navigating Hillwood’s melting pot. Arty visuals and jazz score evoked city soul.

    2000s arcs like “Arnold Saves the Neighborhood” tackled gentrification maturely. Voices by Lane Toran and Francesca Marie Smith captured grit. Six seasons influenced realistic kids’ shows, its 2002–2004 movies capping a legacy.[7] Profoundly heartfelt.

  8. Rocket Power (1999–2004)

    Extreme sports ruled in Arlene Klasky’s Rocket Power, tracking Otto, Reggie, Twister, and Sam shredding Ocean Shores. Fluid board animations mimicked real motion seamlessly.

    Team rivalries and sibling spats in “Super McVarial 900” mixed adrenaline with lessons. Shayna Fox’s Reggie voiced fierce feminism. Five seasons embodied 2000s X-Games culture, spawning games.[8] Pure adrenaline nostalgia.

  9. As Told By Ginger (2000–2006)

    Emily Kapnek’s dramedy elevated tween tales via Ginger Foutley’s voiceover narration, tackling puberty, family, and cliques with Emily Barton’s animation.

    Nuanced arcs like “Gym Catapult” explored anxiety deeply. Voices by Melissa Disney conveyed raw emotion. Six seasons garnered acclaim for maturity, prefiguring Daria successors.[9] Emotionally astute.

  10. Danny Phantom (2004–2007)

    Butch Hartman’s ghostly hero Danny Fenton battles spectral foes as half-ghost teen, with sleek shadows and glows innovating action.

    Identity themes peaked in “Ultimate Enemy,” blending scares and heart. David Kaufman’s Danny oozed cool. Three seasons built fervent fandom, comics extending lore.[10] Spectral supremacy.

  11. Invader Zim (2001–2006)

    Jhonen Vasquez’s gothic sci-fi masterpiece features defective alien Zim conquering Earth incognito, aided/abetted by GIR. Squiggly art and dark humour subverted norms.

    Episodes like “Enter the Florpus” (later film) layered paranoia masterfully. Richard Horvitz’s Zim screamed iconicity. Two seasons plus cult revival defined outsider art on kids’ TV.[11] Irreverently brilliant.

  12. Avatar: The Last Airbender (2005–2008)

    No list omits this pinnacle: Michael Dante DiMartino and Bryan Konietzko’s epic follows Aang mastering elements amid war. Watercolour-inspired animation and martial arts choreography revolutionised TV.

    Philosophical depth in “The Tales of Ba Sing Se” weeps profundity; voices like Zach Tyler Eisen and Mae Whitman embody growth. Three perfect seasons, Emmys galore, spawned Korra and Netflix live-action.[12] Transcendent masterpiece.
