That -other- Sonic cartoon by Dic Entertainment. The show is based on the Sonic the Hedgehog video game series and aired two seasons on ABC from September 18, 1993, until December 3, 1994, which reran until May 1995. Now Sonic and his band of "Freedom Fighters" must stop Robotnik from roboticizing the planet!

The show's first season focuses its subplots on subject matter that is unusual for, and darker than, most American children's cartoons; placing its setting in a post-apocalyptic fantasy world, and using story concepts such as losing family members to war. The first season possesses some minced oaths,and various innuendos. Nevertheless, the cartoon remains family friendly, as this subject matter is depicted in a softened manner.

It was decided that the second season would have several episodes devoted entirely to humor, while "darker" plot developments and possibilities, as well as all violence, were reduced in magnitude. Due to concerns with her more human-like appearance compared to other characters, Princess Sally wore a vest beginning in the second season, whereas in the first season she wore only a pair of boots. Further changes in design include a new color palette for Rotor, Bunny's upper arm no longer being roboticized (as opposed to her forearm and shoulder, which remained roboticized) and a flashier look for the creation of power rings in the power ring pool.

The series sharply contrasts with Adventures of Sonic the Hedgehog, another cartoon series starring Sonic, which had premiered in the same month. While Adventures of Sonic the Hedgehog was very lighthearted and comical, Sonic the Hedgehog featured a more complex plot and dramatic atmosphere. This series is the primary inspiration for the Archie comic book series of the same name, which continues to use elements and characters from this series, albeit with a separate continuity to the storyline.

After the series' initial run, it was aired on the USA Network's Action Extreme Team in reruns from June 1997 to January 1998. Reruns aired in syndication from 2004 to 2005. The series aired in Canada on the CTV Network, with a bonus summer run between June 10 and September 2, 1995, that ABC did not replicate. Sonic the Hedgehog has not been re-run in Canada since its cancellation on CTV. It initially had a complete run on the UK television channel Channel 4 from 1994 to 1996. Season one was broadcast in the Republic of Ireland on RTÉ Two in December 1994.
