Every Sonic Animated Show from the First to Latest, and Where to Stream Them
The blue blur has been racing across television screens for more than three decades, and the sheer number of ‘Sonic the Hedgehog‘ shows can get confusing fast. From syndicated ’90s cartoons to the current ‘Sonic Prime’ era on Netflix, the franchise has reinvented itself again and again while somehow keeping Sonic’s cocky attitude intact.
Whether you grew up with Saturday morning reruns or discovered the hedgehog through the recent Netflix seasons, sorting out the timeline of every animated ‘Sonic’ series is genuinely useful. Here is every major show, listed in order, along with what made each one worth watching or skipping.

‘Adventures of Sonic the Hedgehog’ and the Original ‘Sonic the Hedgehog’ Series
The very first ‘Sonic’ cartoon arrived in the fall of 1993, when two competing shows launched almost simultaneously. ‘Adventures of Sonic the Hedgehog’ ran for a hefty 65 episodes in first-run syndication, playing weekday afternoons for kids racing home from school.
That same September, ABC debuted its own take simply titled ‘Sonic the Hedgehog’, now often nicknamed SatAM by fans to distinguish it from its syndicated sibling. It ran two shorter seasons of 13 episodes each, wrapping its story by the end of 1994.
The two shows could not have felt more different despite sharing a mascot and a premiere month. ‘Adventures of Sonic the Hedgehog’ leaned into slapstick, gags, and a closing “Sonic Says” public service segment, while the ABC series pursued a darker, more serialized resistance story against Dr. Robotnik.
Fans still argue over which format aged better, but both series cemented Sonic as a Saturday morning fixture in the early ’90s and set the template for the tonal split between comedy and drama that would follow the character for years.
‘Sonic Underground’ and the Franchise’s Musical Detour
By 1999, the franchise took a sharp left turn with ‘Sonic Underground’, which introduced Sonic’s long lost siblings Sonia and Manic and gave the trio magical instruments that doubled as weapons. The show premiered on BKN on August 30, 1999, and ran a single 40 episode season before wrapping that October.
Critical reaction at the time and in retrospectives has skewed negative, with the plot frequently singled out as muddled and hard to follow. That said, the show’s original songs performed during episodes have drawn more favorable notice, giving it a strange dual legacy as a cartoon better remembered for its soundtrack than its storytelling.
‘Sonic Underground’ never got the chance to resolve its central mystery about the siblings reuniting with their mother, since the series ended on something of a cliffhanger. A planned comic book conclusion was reportedly considered at one point but ultimately never made it to print due to licensing issues.
Even with its rocky reputation, the show remains a curiosity for long time fans who want to see just how far the franchise was willing to stretch its format in the ’90s.
‘Sonic X’ And The Anime Era
‘Sonic X’ marked the franchise’s first true anime adaptation, produced by TMS Entertainment in partnership with Sega. It began airing on TV Tokyo on April 6, 2003, and eventually spanned three seasons, with the third landing on Jetix in March 2005.
The premise sent Sonic and his friends through a dimensional rift into a world populated by humans, where they befriend a boy named Christopher Thorndyke while chasing down the Chaos Emeralds. Reception has been notably split depending on which version viewers watched, since the original Japanese broadcast is generally remembered far more fondly than the American localization.
The English dub, handled by 4Kids Entertainment, trimmed content, replaced the score, and softened some of the show’s tone, changes that many longtime fans still point to when explaining why the American cut carries a rougher reputation than the source material. The later arc involving the villainous Metarex is frequently cited by fans as the strongest stretch of the entire series, praised for sharper animation and a more emotionally resonant story.
Whatever side of the dub debate viewers land on, ‘Sonic X’ remains a formative entry for an entire generation that discovered Sonic through anime rather than Saturday morning cartoons.
‘Sonic Boom’s’ Comedic Cartoon Network Run
After nearly a decade away from television, Sonic returned in a completely different style with ‘Sonic Boom’, the franchise’s first fully CG animated series. It premiered on Cartoon Network on November 8, 2014, running 52 episodes before a second season shifted primarily to Boomerang starting November 12, 2016.
Rather than chasing serialized plots, ‘Sonic Boom’ embraced a sitcom structure built around a small cast hanging out on Seaside Island, with Sonic, Tails, Knuckles, Amy, and newcomer Sticks trading quips while fending off Dr. Eggman. Critics generally responded well to the shift, with reviewers praising the show’s self-aware humor and colorful character work even as some noted the lighter tone placed it below more plot driven ‘Sonic’ stories in franchise rankings.
The show also carved out a reputation for surprisingly sharp writing, with several critics comparing its dialogue-heavy, hangout comedy energy to sitcoms far removed from typical kids programming. Despite the positive critical notices, Sega opted not to continue the series past its two season run.
‘Sonic Boom’ remains a fan favorite specifically because it dared to be funny first, a choice that still divides opinion among viewers who prefer their hedgehog a little more serious.
‘Sonic Prime’ and the Netflix Chapter
The most recent entry in the franchise’s television history is ‘Sonic Prime’, which debuted on Netflix on December 15, 2022. The multiverse-hopping series ran three seasons total, with season two arriving July 13, 2023, and the concluding season two landing January 11, 2024, closing out the show’s original 24 episode order.
According to Netflix’s own description of the finale, the new episodes pick up right after Sonic teamed with his rival Shadow to rebuild the Paradox Prism, only for Nine, an alternate version of Tails, to betray Sonic and seize the Prism for himself. Critics were largely positive about how the story wrapped, though several noted the final season leaned heavily on repetitive, drawn out battle sequences in its back half.
Reviewers highlighted the emotional throughline between Sonic and Nine as a genuine strength of the closing chapter, alongside praise for the animation’s expressive character work and the score’s ability to underline quieter, more poignant moments. At the same time, some critiques pointed to tonal whiplash between heavier stakes and lighter comedic beats as a recurring issue across all three seasons, not just the finale.
What is your favorite Sonic the Hedgehog series?
With ‘Sonic Prime’ now concluded, some entertainment outlets have floated the idea of Netflix commissioning additional Sonic content given the franchise’s continued popularity on the platform, though nothing has been formally announced. For now, the eight year gap between ‘Sonic Boom’ and ‘Sonic Prime’ stands as the longest the franchise has ever gone without a new animated series.
Which era of Sonic cartoons holds up best for you, the scrappy ’90s originals, the divisive anime years, the comedic Cartoon Network run, or the multiverse chaos of the Netflix seasons, and do you think Sonic Prime deserved one more season to breathe?
