Sonic the Hedgehog: X-treme Adventures (2026 anime)

Sonic the Hedgehog: X-treme Adventures (often shortened to Sonic: X-treme Adventures or simply Sonic X-treme and simply called ソニック・ザ・ヘッジホッグ (Sonic the Hedgehog) in Japan) is an anime adaptation of SEGA’s Sonic the Hedgehog series, and is the 11th animated adaptation of the series (counting the OVA, Sonic Colors: Rise of the Wisps, and the 2 online series, but not counting the live action movies), as well as the 3rd anime adaptation of the series (after Sonic the Hedgehog (1999 OVA) and Sonic X). It airs in TV Tokyo in Japan and Toonami (Adult Swim) in the USA and United Kingdom.

Plot Summary:
Meant as a light-hearted reboot of the Sonic series, “Sonic X-treme Adventures” takes place in Planet Mobius, a planet where humans and anthropomorphic animals live in peace. Enter Sonic, a teenage hedgehog from Station Square with the power to run at the speed of sound and an aditude cooler than the coolest mountains. Upon discovering a secret laboratory, he encounters the evil Dr. Ivo “Eggman” Robotnik, who secretly plans to take over Mobius and make everyone his personal slaves using the magical Chaos Emeralds. To ensure this won’t happen, Sonic teams up with his best friends; Tails, a genius two tailed fox, Chris, a young but clever human boy, and Sara, an over-enthusiastic cat girl with a fangirl-crush on Sonic. Together, this quartet fights Robotnik‘s robotic forces on the regular in comedic encounters hailing back to the first Sonic cartoons. Other characters from the games and cartoons, such as Knuckles, the leader of the Echidna Tribe and Sonic’s rival, Amy Rose, Sonic’s self-appointed girlfriend and Sara’s love rival, Robotnik Jr, Eggman’s non-biological son who disobeys his father regularly and befriends Sonic, and Shadow, a highly advanced clone of Sonic and one of his closest friends, make recurring appearances.
