He is able to run at superhuman speed, and is the only Freedom Fighter capable of using magical rings called Power Rings. Sonic has an impatient and head-strong personality, but is also fearless, heroic, and well-meaning. He always mockingly refers to Robotnik as "Ro-butt-nik".
• Princess Sally Alicia Acorn (voiced by Kath Soucie as her older self and Lindsay Ridgeway as her younger self) is a chipmunk who is the rightful princess of Mobotropolis and Sonic's love interest. As strategist and leader of the Knothole Freedom Fighters, she is knowledgeable and the voice of reason. Sally tries to keep Sonic grounded. She is known for her compassion and master diplomacy.
• Bunnie Rabbot (voiced by Christine Cavanaugh) is a rabbit with a Southern accent. Half of her body was roboticized, leaving her left arm and both legs mechanical. She is skilled in martial arts and wants to be returned to normal.
• Antoine "Ant" Depardieu (voiced by Rob Paulsen) is a coyote with a French accent whose awkwardness often places the others in danger and gets him captured. He has some difficulty speaking English. He has romantic feelings for Princess Sally, and attempts to impress her. However, his selfishness hinders this goal. Sonic often teases Antoine over his shortcomings.
• Rotor (voiced by Mark Ballou in Season 1 and Cam Brainard in Season 2) is a walrus and the mechanic of Knothole Village. He provides the Knothole Freedom Fighters with useful inventions, and accompanies them on infiltrations.
• Tails (voiced by Bradley Pierce) is a young two-tailed fox who idolizes Sonic. While usually left behind in Knothole, he proves useful in deadly missions.

Villains

• Dr. Julian Robotnik (voiced by Jim Cummings) is an evil human warlord who seeks to cover Mobius in machinery and transform its population into robotic slaves by roboticizing them.

• Naugus (voiced by Michael Bell) is a powerful humanoid sorcerer of indeterminate species with bat-like ears, a rhinoceros horn on his head, a crustacean-like claw for a left hand, and a lizard-like tail. He resents his former associate Robotnik for betraying and imprisoning him within the Void. Naugus desires retribution, but he cannot escape without turning into crystal due to him being in the Void for too long as he can no longer exist outside the void.
  • Cluck (vocal effects by Frank Welker) is a robotic chicken-like bird and the only creature Robotnik shows affection towards.
  • Swat-Bots (voiced by Jim Cummings and Frank Welker) are Robotnik's primary henchmen and foot soldiers.

Supporting

• Lupe Wolf (voiced by Shari Belafonte) – Leader of the Wolfpack Freedom Fighters and one of the Knothole Freedom Fighters' allies in the fight against Robotnik.

Series overview

Season 1 (1993)

Season 2 (1994)

Initial run

The Saturday morning series differs from Adventures of Sonic the Hedgehog, which premiered two weeks earlier and aired on weekdays in syndication. While Adventures is lighthearted and comical, Sonic the Hedgehog featured a comparatively complex plot and dramatic atmosphere. It explored unusual story concepts for animation, including losing loved ones to war^[17] and relationships focusing on young couples.^[18][3]

While featuring a darker tone in comparison to Adventures, the Saturday morning show's first season had an episodic structure and aired out of order, however the second season featured a story arc (which would've continued in the later seasons, had the show not been cancelled). At ABC's request, the second season included episodes devoted to humor, while darker and dramatic elements were reduced. Other changes in season two include Princess Sally donning a jacket, Dulcy the Dragon being added to the cast and Rotor receiving a new design. ABC also ended up, in some weeks, airing back-to-back episodes of this show during the 1st season, while in Season 2, each time slot for the show was for a single episode only.^[19]

Syndication

After the program's initial run, it appeared on the USA Network's Action Extreme Team block from June 1997 to January 1998. ABC did not replicate this, replacing Sonic with reruns of Free Willy. Sonic the Hedgehog aired in Canada on the CTV Network, with a bonus summer run between June 10 and September 2, 1995. It has not been rerun on broadcast or cable television in Canada since its cancellation on CTV, but was present on the Shomi video-on-demand platform until its November 30, 2016, closure. In 2004, it started airing on Spacetoon TV in the MENA region until May 2015. All scenes with depicted romance have been censored due to federal laws in Saudi Arabia.^{[citation needed]}

From 1994 to 1996, it had a complete run on the UK television on ITV and Channel 4, In December 1994, the first season was broadcast in the Republic of Ireland on RTÉ2.^[20] On September 2, 2016, reruns of the series began airing on Starz.^[21] As of 2020, the show can be found on demand on Pluto TV on Paramount+, as well as YouTube. On March 15, 2021, it began airing in Malaysia on TA-DAA!.^[22]

In September 2003, DIC revealed a new international package consisting of Adventures of Sonic the Hedgehog, Sonic the Hedgehog and the Sonic Christmas Blast special, titled "Totally Sonic!". The package would also feature digitally re-mastered, color-enhanced versions of the shows with new contemporary music, as well as bonus director's cut "Secret Sonic" episodes.^[23][24]

Home releases

Comics

Archie's Sonic the Hedgehog comic book was initially based on the Saturday morning cartoon.^[26] From its earliest issues, the book shared the characters and story premise established within it. However, the comic differed in that it featured humorous plots modeled after the weekday show.^[27] After writer Ken Penders had the opportunity to view the Saturday morning program, the comic gradually became adventure-driven.^[28]

The comic series shifted focus again after ABC cancelled Sonic the Hedgehog, developing into a relationship-based superhero story, and following a reboot, Archie's Sonic was primarily inspired by the video game series. Nevertheless, the characters and locales from the Saturday morning cartoon remained prominent until the comic's cancellation in July 2017.^[26]

Video games

Several video games were intended to use elements from the TV series, although only one was completed. This was Sonic Spinball, released in 1993 for the Sega Genesis. It contained characters from the show, including Princess Sally, Bunnie Rabbot, Rotor and Muttski. Spinball was commissioned due to Sonic the Hedgehog 3 being pushed back from its intended 1993 release in the holiday shopping season to February 1994, with the game being developed in under a year.^[29] An 8-bit port of the game was also released for the Master System and Game Gear due to the poor reception of Sonic Drift in Japan.^[30]

Another video game tentatively titled Sonic-16 was intended to be set in the same universe, with a prototype being created by Sega Technical Institute in November 1993. However, Yuji Naka and Sega management disliked the project, allgedly due to its slow-paced nature, and it was soon cancelled without any further development.^[31][32][33] Directly afterwards, the same team worked on Sonic Mars; this would have featured Princess Sally and Bunnie Rabbot as playable characters.^[34] This project eventually evolved into Sonic X-treme, which was cancelled in 1996 due to development difficulties.^[35][36] Hackers also found within the data of the arcade game SegaSonic the Hedgehog (1993) a near-complete sprite sheet for the Robotnik design used in the cartoon, with it being speculated it was to be used in a scrapped English localization.^[37]

In the North American Sonic CD manual, Amy Rose is identified as Princess Sally.^[38]

Revival Attempts

The co-story editor of the show's second season, Ben Hurst, spent many years trying to revive the series through various media. He would go on to write for Sonic Underground, but unfortunately, due to the plot of the series already being set in stone by the time he, and his co-writer Pat Allee, came on board the series, they were unable to do so. Ben would later state that, had he been brought on to the series first, he would've made it the third season of Sonic SatAM. He would also state that, if forced to include songs in the series, he would've either simply had it play over footage, or had Bunnie and Antoine^[39] (or Tails, according to his friend Allison Scharlemann),^[40] sing the songs.

Ben would later attend San Diego Comic Con in August 1999, meeting the head writer of the Archie Sonic comics, Ken Penders.^[41] Ben expressed interest in wrapping up the SatAM story in a comic, with him eventually being offered a Sonic Super Special. However, Ben eventually decided to pass on this. Ken said the reasoning was that he passed because Archie's pay rates were much lower than that of animation writing. Although Ben would additionally state a while after this that it simply wouldn't have been possible to conclude the series in a single comic, and would need at least 17 to 20 issues to properly conclude the story.^[42] Ken’s retellings of the story would also feature some contradictions, as in an earlier telling of these events, he stated Art Mawhinney, a storyboard artist for SatAM, would’ve been assigned to do the art for this Super Special.^[41] However, he would later on state that Patrick “Spaz” Spazinate was actually assigned to the pencils, with Ken likely having done the inking.^[43]

After this, Ben looked into other avenues for continuing the SatAM story, with him considering the idea of either reviving the series for a third and fourth season,^[44] before considering the idea of instead concluding the story in a film.^[45] He’d eventually have a meeting with DiC executive Robby London on February 29, 2000. Ben learned quite a bit about the animation industry, and realized that reviving the series for more televised seasons simply didn’t seem viable. While he said direct to video was more likely, he felt the best bet was to attempt to conclude the SatAM story as a feature film. Robby London gave Ben the number of a Sega executive. “My marketing strategy is simple: a great film could create an awakened interest in Sonic, breathe new life into the existing produced series and increase the marketing and merchandising possibilities for the little blue guy.”^[46]

Hurst would eventually call said the Sega executive, explaining his idea for a Sonic feature film to her, to which they had a very pleasant conversation, and she said she’d like to talk again.^[47] The next day, Archie Sonic writer Ken Penders gave him a call, alerted by his contact in their office that he was interested in getting a Sonic movie going. “I generously offered to include him in the effort and told him my strategy. Get SEGA to become invested in the idea by hiring us to interview their creative game designers, execs, etc and see if we could develop a story line that would fulfill the third season - and simultaneously give them creative ideas to develop new games. A win-win, situation.”^[47] However, once he called Sega back, his contact's demeanor had completely changed; they angrily stated that Sega is paid to develop Sonic projects, rather than paying others to do so. Hurst theorized that Penders had told them about their strategy in a "less-than-flattering way".^[47]

While this event caused Ben to briefly give up on trying to revive the SatAM series, he would eventually start working on it again once more. During 2003, Ben would start writing a story document for the conclusion film,^[48] and, according to him, he had dozens of notes with story ideas on them.^[39]

In 2005, Ben’s best friend (and husband to his sister) was diagnosed with cancer, and was given only months to live. After a long talk with him about their long friendship, the topic of Sonic came up once again. “As we were discussing it, he reminded me that none of us know how long we will be allowed to stay here on earth. Then, he put his hand on my shoulder and informed me, ‘Ya gotta follow your dreams,’ and with a grin, he added, ‘Juice and jam time for both of us.’”^[49] With this discussion, Ben decided to try and revive the film project one more time. His last plan to get the SatAM movie out was to get a completely separate movie out, and then use his name on that movie to pitch the SatAM movie.^[40] Len Janson helped write the script, a film entitled “The Gift”, loosely based on the story of “Le Pétomane”.^[39] However, this attempt also failed, with him saying “I don't think it will ever sell. It would be a monster hit, but Hollywood Execs are scared to death of it.”^[39]

Ben still never gave up hope, and apparently planned to try one more time, by gathering a group of fans together to make a presentation for Sega. However, this would not come to pass.^[40]

Ben Hurst would later pass away in August 2011, and his good friend, Allison Scharlemann, would release what she had of Ben Hurst’s notes for the SatAM film.^[50] Allison would later share more details she remembered from her conversations with Ben on forums, the Ben Hurst memorial,^[51] and for “Ben’s Vision - The Lost Sonic SatAM Third Season/Film”, a documentary which told the story of Ben Hurst’s many revival attempts, and what was known of Ben Hurst’s plans for the unmade film/season.

Team Sea3on

From 2019 onwards, a group of fans calling themselves 'Team Sea3on' spun out from the online "FUS" community ("Fans United for SatAM,") and began work on bringing a third season of the series to life, basing the plot lines on both Ben Hurst's original notes as well as the group's active webcomic. The group are presently working within 'proper legal channels' to advance the project with Sega's awareness. The effort gained attention from the likes of IGN.^[52] In April 2022, a full teaser trailer was uploaded to the group's YouTube channel,^[53] with a cover of the SatAM theme song "Fastest Thing Alive" by Johnny Gioeli of Crush 40.^[54]
