* CreatorBacklash: According to Milton Knight, many of the staffers openly despised working on this show. Knight himself enjoyed working on it, but found the animation, writing, and most of the voice acting to be quite shoddy.
* DependingOnTheArtist Creator/{{TMS|Entertainment}}: As anyone can tell you, TMS did 5 episodes and the opening. However, due to ''Anime/FarewellToNostradamus'' and a smaller budget then what TMS normally got from Creator/WarnerBros [[WesternAnimation/{{Animaniacs}} on their shows]], the bulk of the animation was outsourced. Listed below are the animation directors and outsourcing units used during production.[[note]] Much like ''WesternAnimation/TinyToonAdventures'' and ''WesternAnimation/BatmanTheAnimatedSeries'', they were uncredited for the work.[[/note]]
** Opening: Creator/ToshihikoMasuda; In house.
** "Quest for the Chaos Emeralds Part 1"[=/=]"Blackbot the Pirate": Kazuhide Tomonaga; Creator/NakamuraProductions.
** "Quest for the Chaos Emeralds Part 2"[=/=]"Hedgehog of the Hound Table": Kenji Hachizaki; Creator/AnimeSpot.
** "Quest for the Chaos Emeralds Part 3"[=/=]"Robotnik's Pyramid Scheme": Atsuko Tanaka; Creator/{{Actas}}.
** "Quest for the Chaos Emeralds Part 4"[=/=]"Prehistoric Sonic": Toshihiko Masuda; Creator/StudioJungleGym.
** "Super Robotnik": Kenji Hachizaki (first half, left during production to work on ''Farewell to Nostradamus''), Yuichiro Yano (second half), Hiroyuki Aoyama (the ''Sonic Sez'' segment of the episode); in-house.
* DependingOnTheArtist ([[Creator/HongYing ot]][[RainbowAnimation her]] [[{{Saerom}} studios]]): The quality of the characters and animation as a whole tend to change between episodes.
* ExecutiveMeddling: ''Sonic Christmas Blast'' was originally intended to be titled ''An X-Tremely Sonic Christmas'' as a tie-in with the game ''Sonic X-treme'', but the game's cancellation forced it to be titled for ''Sonic 3D Blast'' instead.
** Dr. Robotnik was originally conceived as television's sexiest fat man. The animators weren't up to the challenge, but it didn't stop them from slipping in a lot of {{shirtless scene}}s and scenes that draw too much attention on Robotnik's rear end (and, of course, the completely unnecessary bikini pic from "Hero of the Year.")
* FakeAmerican: Jaleel White was the only American voice actor. Everyone else in the cast was based in Vancouver. Although...
** Averted with Robotnik, since Long John Baldry makes [[NotEvenBotheringWithTheAccent absolutely zero attempt to mask his native British accent]].
* HeyItsThatSound: The episode "Grounder the Genius" features two of the actual sound effects from the ''Sonic'' games[[note]] [[VideoGame/SonicTheHedgehog The]] [[VideoGame/SonicTheHedgehog2 first]] [[VideoGame/SonicTheHedgehogCD three]][[/note]] in one part of one scene; specifically, the "jump" and "ring" sound effects.
** One episode has [[http://www.youtube.com/watch?v=5V8In4rQqe0 Mario sound effects when Robotnik pushes a few buttons]]. This could be due to the fact that [[Creator/DiCEntertainment DiC]] also made the ''Mario'' cartoons, so they certainly had the sound effects on-hand already.
** One of the "running" sound effects (used in numerous other cartoons) would later be used as one of the sound effects when landing on a spring in modern ''Sonic'' games.
** The Mario sound effects later appear in "Attack of the Pinball Fortress".[[note]] the ''VideoGame/SonicTheHedgehogSpinball'' episode.[[/note]]
** The "derez" sound effect from ''Film/{{Tron}}'' can be heard in "Robitnik's Rival".
** The "spider" sound effect from ''VideoGame/{{Centipede}}'' can be heard in "Coachnik".
* HeyItsThatVoice: If you grew up in the 1990s with the TGIF block on ABC, you will recognize the voice of Sonic as [[Series/FamilyMatters Steve Urkel]]. Older viewers, particularly the parents of the viewing demographic, will recognize the voice of Dr. Robotnik as the late singer Long John Baldry who was also the voice of [[WesternAnimation/ReBoot Captain Capacitor, the Crimson Binome]].
** In season 1 [[ReBoot Hack and Slash]] were played by Phil Hayes and Gary Chalk just like Scratch and Grounder. Both were duos of inept villainous robot henchmen.
** Coconuts was Creator/IanJamesCorlett, who was Dr. Wily in ''WesternAnimation/CaptainNTheGameMaster'', and the main character in the ''WesternAnimation/MegaMan'' Ruby-Spears cartoon and the Ocean dub's version of Goku in ''Anime/DragonBallZ''.
** Scratch is [[WesternAnimation/TheRenandStimpyShow Ren]] in Brazil and Stimpy in Germany!
** Katella was voiced by Kathleen Barr who also did the voices of Trixie and Queen Chrysalis from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' and Truman in ''WesternAnimation/DinoBabies''.
** In Italy, Sonic is {{Pingu}}.
** Breezie is [[Manga/RanmaOneHalf Female Ranma Saotome]] and [[WesternAnimation/CaptainNTheGameMaster Princess Lana.]]
** Professor Von Schlemmer is [[Manga/{{InuYasha}} Kagome's Grandpa.]]
** Oneshot villain Dr. Qwark ([[BerserkButton Not QUACK!]]) is [[WesternAnimation/MegaMan Cutman,]] [[Anime/DragonBallZ Krillin, Master Roshi]] and [[WesternAnimation/EdEddNEddy Eddy's Brother.]]
** Masonic's bride Penelope from ''Obotnik's Pyramid Scheme'' and Robot the Robot are [[WesternAnimation/MyLittlePonyFriendshipIsMagic Spike,]] [[Manga/DeathNote Near]] and [[Manga/{{Inuyasha}} Kagome's Mother.]]
* IronyAsSheIsCast: Robotnik sings much worse than his voice actor, Long John Baldry.
* PlayingAgainstType: Coconuts' voice actor Ian James Corlett is also the voice of Mega Man in the Ruby-Spears}cartoon.''WesternAnimation/SonicUnderground'' didn't help either.
* TalkingToHimself: Katella and Mama Robotnik are both voiced by Kathleen Barr. When she was playing Mama Robotnik in "Zoobotnik" she made her voice lower and gruffer than she had sounded previously.
* WhatCouldHaveBeen: The cartoon was going to last longer, but it played the SixtyFiveEpisodeCartoon trope straight.
** There was a workprint of a pilot episode that was screened when the cartoon was being pitched to ABC. Unfortunately, the network hated it and instead preferred [=DiC's=] [[WesternAnimation/SonicSatAM second idea]] of a ''Sonic''-themed television series, ultimately leading to the pilot being scrapped. The workprint itself can be seen on Website/YouTube.
