History Anime / SonicX

** The Latin American Spanish dub of the show refers to Sonic as a porcupine.

** In the French dub, Knuckles was initially called a hérisson (hedgehog) instead of an échidné (echidna). Later on, during the Metarex saga, there are a few scenes where Yellow Zelkova mistakes him for a hedgehog. However, the dub's translator still managed to incorrectly identify Knuckles' species, as the echidna would 'correct' Yellow Zelkova by saying he's a porc-épic (porcupine).

** The French dub initially referred to Knuckles as a hedgehog. Later on, he says that he's a porcupine.

* BittersweetEnding: [[spoiler:The Metarex are defeated and the galaxy is saved, but Cosmo is dead, Shadow is missing (though the Japanese dub confirms he's still alive), Chris goes back to Earth (possibly never to return), and Eggman resumes his plans to build the Eggman Empire, with [[AndTheAdventureContinues Sonic and friends getting ready to stop him]]. However, Cosmo's seed has begun to sprout.]]

* {{Bowdlerise}}: The English dub doesn't just spoil the jokes; it also cuts out whole scenes - in Season 3, Shadow and Rouge visit a bar. More than ''75 seconds'' is cut, even though it's an alien planet, neither of them drink the alcoholic beverages, there is no alcohol on show (just bottles), they're solid anti-heroes, and it's some pretty important exposition. This sort of thing happens all over the place, even with things that ''weren't'' censored in the English localizations of the games, like the police shooting Chaos, the "Casino" sign on Casinopolis, and Maria's [[NeverSayDie death not being directly referred to]].

** In the sub of episode 10, during the baseball game against Eggman, Sonic catches a home run ball outside the fence and is told by Chuck that it's against the rules. 
---> '''Sonic''': "Why do we have to play by the rules now? This is an anime."
** When Sonic is getting squeezed to death by the E-99 Egg Emperor (E-99 Eggsterminator in the dub), Decoe and Bocoe ask Eggman if he's really going to kill Sonic. He replies in the negative and rants about how there would no longer be a show if the bad guys won and eliminated the hero. Note that this was an [[ThrowItIn improvised line]] by Chikao Ōtsuka, Eggman's Japanese voice actor, as in the original script Eggman didn't have any lines at this point.

* CampingEpisode: Episode 22 involves the cast going on a camping trip to watch wildlife. [[spoiler:It ends up with Chris and friends discovering a Chao garden, and according to Tanaka, that garden was there when he was a kid]].

** In Episode 57, Knuckles' arguing with the others (once again warning of how Eggman abuses him) leads to a planet egg getting stolen; he attempts to retrieve it but it turns out the one he collected was a fake, with Sonic and Chris using Knuckles as a distraction while they protect the real thing. After Knuckles is shown to be humiliated by this they give him a somewhat condescending pat on the back, the basic moral seeming to be, "It's okay for ''us'' to use you." Ironically the dub subverted this somewhat in this scene, in which Cosmo comforts Knuckles (humiliated about Eggman using him) claiming he only believes the doctor's lies because [[JerkWithAHeartOfGold he believes in peace and that anyone is capable of good.]]

* DependingOnTheArtist: An animation example. Sonic X has at least a dozen different animation directors that take charge depending on the episode. As such, way characters look and animation quality depends on who's the animation director of the episode. If you want to see who did what episode(s) go [[https://drawloverlala.tumblr.com/post/143866703916/ever-wondered-why-sonic-x-varied-so-wildly-in-art here]]

* DubSpeciesChange: The Latin American Spanish dub of the show refers to Sonic as a porcupine.

* EvenEvilHasStandards: From the [=4Kids=] dub: "It's one thing to take them prisoner and threaten them but when you actually hurt somebody, that's going too far".

* {{Filler}}: While Sonic X did manage to avoid this for the most part, it still had it's episodes. The worst example is Season 1, where out of the 26 episodes, '''ten''' of them are filler

-->'''Espio''': Change the scene and suddenly you know where Sonic is. Is it just because the program's almost over?

** The final comic also does it when Shadow from the main Archie comics ends up in the Sonic X comic through Chaos Control. Many an AsideGlance is cast.

* LargeHam: Shadow, Knuckles, and Chris's uncle, Sam Speed.

** For a more specific example, they in fact had to cut down Sonic's animation design. In the games he always has six quills on his back, which got reduced to only three in the show. For the most part it works, because that's all we usually see in his portrait view, but it's apparent when they have to show him from behind.
* LiteralMinded: When the X-Tornado is coming in for a landing on the Egg Carrier, Eggman says "let's give them a warm welcome, shall we?" Cue Decoe pressing a button that [[ComicallyMissingThePoint disperses confetti and activates robot cheerleaders]] that [[FlatJoy flatly cheer "hip hip hooray!"]] Bocoe {{Face Palm}}s in response. An arguable case of Woolseyism in the dub, as in the Japanese edit this nonsensical mechanism is activated due to a lack of ammo.

** Sonic in the Japanese dub of Episode 2, ''right in front of Cream''.

** In the Japanese dub of Episode 52, while Tails is being locked onto by a interceptor missile, he exclaims, "Damn! It's over for me!"

* ArtisticLicenseSports: Averted and played straight in the BaseballEpisode. On the one hand, they did get it right when Sonic ran onto the scoreboard to catch a fly ball, and it was still declared a home run because it was caught out of the field of play. On the other hand, when the robot pitcher is charmed by Cream and commits a balk, Cream is allowed to go to first base. Normally a balk just allows any runners on base to advance.

** Episode 16 is another one. There is one scene of Amy & Cream showing off their swimsuits followed by them playing in the water and you also have Tails and Cheese relaxing by a rock, both of whom are wearing shades.

---> '''Charmy''': "Ladies and gentlemen, welcome to another episode of Delusional Thinking With Vector! Just look at him go, ladies and gentlemen! He's out of control! There's no stopping him!"

** Espio is this too. Especially when he's with his 2 Chaotix team-mates, Vector and Charmy.

** In "Galactic Gumshoes", Chaotix are sent to deliver provisions to the main crew in outer space. Unfortunately they happen to be especially on-edge about Metarex invasions at the time, and attack anything remotely alien on their ship, naturally leading to [[PoorCommunicationKills several unfortunate misunderstandings where the Chaotix end up getting pummelled]]. It is only because Tails is zealous enough to [[YouShallNotEvadeMe try attack their ship post-retreat]] that they realise who it is and meekly apologise to the now beaten down Chaotix.

* CulturalTranslation: In the first Chaotix episode, Vector's references to ''Manga/CaseClosed'' are changed in the dub to references to Sherlock Holmes and ''Series/{{Columbo}}'' -- and yet, [[{{Bowdlerise}} the dub edits the cigar out of Vector's hand]], which would have strongly accentuated the reference.

--> '''Tails''': I can't believe it, Sonic's swimming.

** In a scene played for laughs, Charmy bawls his eyes out. Vector told him to stop crying then Charmy immediately stopped with a grin.

* NiceGuy: Tails, Cream, Cosmo are the prime examples. Amy was one in the earlier episodes of the second season due to them being adapted from the [[VideoGame/SonicAdventure Adventure]] [[VideoGame/SonicAdventure2 games]].

--> '''Sonic:''' [[GratuitousEnglish Shit!]] Let's go!
** In the Japanese dub of Episode 52, while Tails is being locked onto by a interceptor missile, he exclaims, "Damn! It's over for me!".

--->'''Narrator:''' Last time on Sonic X...

-->'''Eggman''': You figured out my scheme, kid. I despised Sonic so much I decided to [[spoiler:bring time to a stand still]]. Then, I tricked this world's scientific expert into believing that Sonic had to be sent back. Now that you caught me, I'll confess.

** The X-Cyclone has a [[{{Anime/Robotech}} Gerwalk]] mode.

--> '''Dark Oak''': "Good job, White Seed. You accomplished your mission.

** The name of the show

* YouWontLikeHowITaste: Sonic's excuse to prevent a shark from eating him in [=H2Whoa=].

Not to be confused with the [[WesternAnimation western animated]] series based on ''Sonic the Hedgehog'', ''WesternAnimation/AdventuresOfSonicTheHedgehog'', ''WesternAnimation/SonicTheHedgehogSatAM'', ''WesternAnimation/SonicUnderground'' or ''WesternAnimation/SonicBoom'', or the {{OVA}} ''Anime/SonicTheHedgehogTheMovie'' and the [[Film/SonicTheHedgehog2020 2020 film adaptation]] from Paramount.

* AdaptationDistillation: The second season roughly adapt the plot of ''Videogame/SonicAdventure'', ''VideoGame/SonicBattle'' and ''Videogame/SonicHeroes'', but in a simplified way.

** Scarlet Garcia (the stand-in from the reporter in the game) meets the man who killed Maria ([[TheGhost Unseen]] in ''Adventure 2'', but he appears in ''Videogame/ShadowTheHedgehog''), and he recalls his side of the story, showing [[FakeMemories how messy Shadow's memories truly are.]]

** In the games, Amy's first encounter with Sonic involves her being rescued from Metal Sonic, as shown in ''Videogame/SonicCD'' and a flashback of ''Videogame/SonicAdventure''. In the flashback on their first encounter in the anime, Metal Sonic is replaced with a generic robot.
** While the anime adapted the cast from the adventure era (''Videogame/SonicAdventure'', ''Videogame/SonicAdventure2'', ''Videogame/SonicBattle'' and ''Videogame/SonicHeroes''), E-123 Omega, the third member of Team Dark, is not included in the adaptation.
** Gemerl, Eggman's robot created from Emerl's data from ''Videogame/SonicAdvance3'' is not included in the adaptation.

** [[ZigZaggingTrope Zig-Zagges]] in Seasons 1 & 2. It mostly whose's the animation director of the episode (see DependingOnTheArtist below.

** Decoe, Bocoe, and Bokkun. Before ''Videogame/SonicColors'', Eggman wasn't know for having robot lackeys outside the ''WesternAnimation/AdventuresOfSonicTheHedgehog'' cartoon.

** In the first season finale of the dub, we get this exchange, which gains a bit more impact when you realize this show later featured an adaptation of ''VideoGame/SonicAdventure2''.
--->''[Eggman uses a more powerful than average explosive]''
--->'''Bocoe:''' One of these days, you're going to blow up the whole planet.
--->'''Eggman:''' It's a distinct possibility.

--->'''Chris:''' [[spoiler:If [Sonic] can survive, then we can too! Isn't that right, Cosmo?]]
--->[''Cosmo doesn't say a word'']

** The first 26 episodes used the show-exclusive E-Series robots in this role. After this, the show decides to adapt the videogames.

** In an early episode where Sonic & co. have recently entered the human world, Tails needs to hide from Stella as Chris and Chuck are the only ones who know of his true nature. Tails decides to masquerade as an inanimate doll on the spot. An actual Tails Doll made an appearance in ''Videogame/SonicR''.

** Big the Cat has a minor, subtle one. Big only interacts with three characters from the games in the anime: Sonic, Amy, and Cream. The only interaction he has with Sonic is an unused line in ''Adventure''; the last two are his friends and team members in ''Videogame/SonicHeroes''.

* ReformedButNotTamed: Shadow much like the games continuity. He returns in the Metarex saga with his memories erased, but remains cold around others and is ruthless in reaching his goals. He's largely more ruthless and less personable than his game incarnation (who mellowed out a bit more after his [[VideoGame/ShadowTheHedgehog own title game]]).

* TruerToTheText: Even with all the new additions and changes, ''Sonic X'' is undeniably one of the most faithful and source-accurate animated adaptations of ''Sonic the Hedgehog'' to date; in fact, it's the only one to actively adapt the storylines of the games (particularly ''VideoGame/SonicAdventure'', ''VideoGame/SonicAdventure2'' and to a lesser extent ''VideoGame/SonicBattle'').

* ApocalypseHow: During the Metarex saga, the Metarex have already inflicted multiple Class 5's/6's on the galaxy, and are prepared to do the same to Sonic's world. Their whole goal during this saga is "Galactic Forestation", which would drop a good ol' fashioned Class X-3 on the galaxy (X-3 classification justified because while stars and planets admittedly aren't being destroyed, killing or turning untold numbers of fauna keystone species across untold amounts of worlds would definitely wreak all kinds of environmental/ecological havoc). After this plan was stopped, the mastermind decided that [[Main/SoreLoser if he couldn't have the galaxy his way, no one would have the universe at all,]] and upgraded this generally localized Class X-3 to a Universal Class X-4, which would have succeeded if not for an ally [[Main/HeroicSacrifice conveniently stepping in]] and allowing the heroes to finish off the villain once and for all.

* BellyDancer: In Episode 47, Decoe and Bocoe head into a cabaret to escape from Knuckles. The echidna walks into the establishment and discovers it to be based on the Arabian Nights, with its workers dressed like harem girls and belly dancers. Out of embarrassment, Knuckles runs away from the cabaret, leaving Decoe and Bocoe in the clear to report back to Eggman... but not before they stay behind to have a little fun with a couple of the dancing girls. Naturally, this whole sequence is cut from the English dub.

* BizarreSexualDimorphism: Cosmo's Rage. Males look like brutish monsters, females look like [[CuteMonsterGirl cute monster girls]]. When entering Mover Mode/the Final Form, the former transform into huge Godzilla-esque monsters, while the latter become huge trees.

** The traditional Badniks only appear in the [[ComicBook/SonicX comic book adaptation]].
