Tagline for the promotional of the sub in Japan

Sonic X is an anime based on the Sonic the Hedgehog video game series, mainly the Sonic Adventure series. Produced by TMS Entertainment, it is the first non-American Sonic animated series to have made it past the first two episodes. It is also the spin-off series closest to the game canon.

The series' first two seasons focus on Sonic and friends being transported to Earth, where they meet and befriend a boy named Chris. The second season alone also focuses mostly on re-tellings of Sonic Adventure, Sonic Adventure 2, and Sonic Battle, except with a few new human characters involved in the stories. The third season is Darker and Edgier and involves Sonic's crew trying to save the universe from the evil Metarex.

The series adapted into a 40 issue American comic book by Archie Comics, set somewhere before the end of the second season. Chronicling the further adventures of Sonic and friends, and introduces the shadowy anti-Sonic organization; The Society for Observing and Neutralizing Interdimensional Creatures and Xenomorphs.

Dubbed and subbed versions are available on Hulu, but only for those in the U.S., and the entire series is also available dubbed on TMS's official YouTube channel. Discotek Media has released the entire series on DVD and Blu-Ray, though currently only the dubbed version. However, they revealed on October 24th, 2022 that they're releasing a Blu-Ray of the subbed version in 2023.

Not to be confused with the western animated series based on Sonic the Hedgehog, Adventures of Sonic the Hedgehog, Sonic the Hedgehog (SatAM), Sonic Underground or Sonic Boom, or the OVA Sonic the Hedgehog: The Movie and the 2020 film adaptation from Paramount.


  • 2D Visuals, 3D Effects: The X-Cyclone would often appear as a highly-detailed and rather realistically shaded CGI model for shots that didn't have the characters in the cockpits or standing on its hull visible, and several times with traditionally-animated vehicles in the same scene. The Egg Carrier was also rendered in CGI in most of its appearances, but it was toon-shaded to closer resemble the traditional animation. It even gets even better when you figured out that the 3DCG animations was produced by TMS' subsidiary studio, ufotable.
  • Aborted Arc:
    • At the start of the Sonic Adventure 2 arc, Eggman realizes that he must have been born on Earth after finding government records of his grandfather. This plot line doesn't go anywhere and we never learn how he ended up on Sonic's world.
    • A small character arc involved Bocoe and Decoe getting sick of Eggman's evil activities and doing a Heel–Face Turn, aligning themselves with Sonic and his friends. The episode after this suitably showed the two living at the Thorndyke mansion with the rest of the gang and helping out around the house. After that episode, this was pretty much abandoned for no clear reason. The closest thing to an explanation was a line or two somewhat implying that Eggman convinced them to come back.
    • After Chris travels to Sonic's world, his friends and family are only occasionally shown being concerned about him. There is no exploration of how their lives have changed six years later. Did Mr. Tanaka end up with Topaz? Is the same President still in office? Did Sonic leave a long-lasting impact on the world? What about Chris's friends? There are no answers.
  • Absurdly Youthful Father: Chuck, Nelson's father, is 55 in the first part of the series while Nelson himself is 43. This means that Chuck had Nelson at only 12 years old.
  • Adaptational Early Appearance:
    • Rouge originally didn't appear until Sonic Adventure 2, and Cream & Cheese until Sonic Advance 2. Here, they're involved before the first Adventure.
    • As an example of an ability showing up earlier than canon, Chaos Control is activated by pure accident in episode 1, also well before the Adventure 2 arc.
  • Adaptational Explanation: In Adventure, Lily (the bird Amy rescues) simply falls out of the sky in front of Amy, with no explanation of where she came from or how she escaped from Eggman. In the anime's adaptation, she's explicitly seen falling out of a hole in the Egg Carrier's hull, inflicted by the X-Tornado during Sky Chase Act 1.
  • Adaptational Jerkass: Amy in season 3 is more aggressive towards her friends than in the two first seasons and the games.
  • Adaptation Distillation: The second season roughly adapt the plot of Sonic Adventure, Sonic Battle and Sonic Heroes, but in a simplified way.
    • The Adventure game is adapted in six episodes.
      • Tikal, who in the game appears to all six playable characters, only appears to Knuckles (who has a personal connection due to the Master Emerald) and Sonic.
      • Knuckles and Tails' backstories were adapted in the first season, leaving only Amy and Gamma to be explored in the adaptation.
      • Most of the bosses, up to and including Perfect Chaos, go down in just one hit. Sonic and Knuckles actually have more difficulty defeating Chaos' base form than they do defeating Chaos 6!
    • Heroes, which has an Excuse Plot is roughly adapted in episode 39. In the game, the Chaotix are hired by a mysterious client to do multiple missions in order to stop Eggman, who is secretly Metal Sonic; Eggman is their client. In the anime, they were hired by Vanilla to find Cream. The Shadow amnesia plot is adapted with his return in season 3.
    • Battle is the biggest simplification, in 5 episodes. The story of Battle is about Emerl being found by Sonic and friends, and him learning to fight and bonding with all of them. The anime simplifies it by him being found by Bokkun and then Cream, with only his relationship with Cream being of focus in her Day in the Limelight. In the game, Emerl turns rogue after obtaining all seven Chaos Emeralds, while in the anime, he only goes rogue with one. Nothing about his past is ever explored either.
  • Adaptation Expansion: Sonic X expands on the setting of the two Adventure titles.
    • For starters, the characters of the President and his assistant and the nameless reporter from Adventure 2 become recurring characters way before the adapatation of the arc, the latter in the form of Scarlet Garcia.
    • Thanks to her early introduction, we see how Rouge joins G.U.N. and how she meets the Sonic cast. In the game, she was introduced in an awkward manner, with Knuckles and her seemingly knowing each other.
    • There is an expansion of the G.U.N. robots from Adventure 2, who had no known background (in fact, the games imply they existed even 50 years prior). In the anime, they were created using Eggman technology stolen by G.U.N.
    • Scarlet Garcia (the stand-in from the reporter in the game) meets the man who killed Maria (Unseen in Adventure 2, but he appears in Shadow the Hedgehog), and he recalls his side of the story, showing how messy Shadow's memories truly are.
  • Adaptation-Induced Plot Hole:
    • In Episode 23, the show adds a plot point to the Chaos Emeralds that explains the following: If two Chaos Emeralds have been away from each other for a while that are in close proximity to each other, the Emeralds will "repel each other violently and unleash powerful electromagnetic waves" as quoted from the Japanese version of the anime. This plot point is fine and expands the lore for the Chaos Emeralds a bit, but when you go over the show again, this plot point falls apart and massively overcomplicates things. For one, There have been a few instances of Emeralds being exposed in very close proximity to each other, but nothing happened (ex: Episodes 10, 13, and 16). It also falls apart when it's a plot point that Chaos Emeralds can at attract each other to their energy. If that's the case, why would they attract each other to their energy if they're just going to repel the moment the other Emerald gets too close? And the worse part is that this point is only used twice. Those two examples being Episode 23 as stated above and a brief mention in Episode 25. Other than that, it's never brought up again (though it might be because the writers realized how tedious and complicated this plot point was).
    • Inverted in the Adventure arc, where omitting a line from the game actually fixes a plot hole. In the game, Eggman notes that the Egg Carrier "pales in comparison to the power of Chaos", yet his backup plan in case Chaos betrays him is... another Egg Carrier. In the anime, Eggman makes no such comparison, making the Egg Carrier 2 sound genuinely sensible as a backup plan. It still gets taken out by Perfect Chaos with little effort, but this time it's actually somewhat of a shock.
    • Eggman has a realization that he was born on Earth, but this ended up never being elaborated on. It's unknown how Eggman ended up on Sonic's World and why he has no memory of his past on Earth. In Sonic Adventure 2, Sonic and his peers live on Earth amongst humans. This is made worse by the later reveal in Season 3 about Sonic's World functioning on a Year Inside, Hour Outside system of time relative to Earth, meaning either Eggman is seriously Younger Than They Look, or he was several decades Maria's senior despite the two being cousins.
    • The anime follows Shadow's backstory from Adventure 2 to a T but never explains how (or why) humans from Earth created a Funny Animal and why this Funny Animal just so happens to look like Sonic's kind. In the games this is explained by Funny Animals and humans coexisting.
  • Adapted Out:
    • In the games, Amy's first encounter with Sonic involves her being rescued from Metal Sonic, as shown in Sonic CD and a flashback of Sonic Adventure. 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 (Sonic Adventure, Sonic Adventure 2, Sonic Battle and Sonic Heroes), 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 Sonic Advance 3 is not included in the adaptation.
    • While all three characters appear in the anime at one point, Chaos, Gamma, and Shadow are removed from the Sonic Battle arc.
    • The Black Arms who made their debut in Shadow the Hedgehog do not appear in the anime. The Metarex instead take their place as antagonist in Season 3.
    • The traditional Badniks only appear in the comic book adaptation.
  • Added Alliterative Appeal: In the dub, every Previously on… is a mass of alliterations. Eggman also makes plenty of them.
  • Advertised Extra: Shadow the Hedgehog. The first two seasons consists of 52 episodes, yet he only appears in the Adventure 2 adaptation of 6 episodes. This is quite egregious, as the Japanese intro song constantly shows him, suggesting he is Doctor Eggman's lieutenant, or at least a recurring character. The opening even has him as Super Shadow fighting Super Sonic, something that never happened in the games. This is due to the intro song using footage from the scrapped pilot. That being said, the third season does have Shadow as a recurring character, subverting this trope.
  • Aloof Ally:
    • Knuckles, though a lot friendlier than regular examples, usually keeps to himself, and doesn't get into the action until the situation truly becomes dire.
    • Shadow helps out Sonic and his friends when needed, but remains distant and is not an actual member of the team.
    • To a lesser extent, Sonic himself. When not fighting Eggman, he's usually doing his own thing without a care about anything or anyone else. However, he can also be friendly and supportive toward others, especially Chris.
  • Alternative Foreign Theme Song:
    • The English dub used "Gotta Go Fast" as its theme song instead of "Sonic Drive".
    • Dubs in most European regions opted for a different intro altogether, which repeats the show's title multiple times.
    • The Italian theme is much slower and has a more electronic sound, which doesn't sound like the other versions.
  • Ambiguous Time Period: The games don't specify any dates. Sonic X, however, takes place 20 Minutes into the Future. Gerald's diary was written during "20XX", pinning the series at 2050 at earliest.
  • Anachronism Stew: The characters dress and act like they're in the 2000s, however Gerald Robotnik's 50-year old diary was written in "20XX" and technology is more advanced than contemporary times. This aesthetic extends into flashbacks as well. 50 years ago looks remarkably 1940s-1960s, yet Maria and Gerald also live in a futuristic space colony.
  • Animation Bump:
    • Zig-Zagges in Seasons 1 & 2. It mostly whose's the animation director of the episode (see Depending on the Artist below.
    • Starting with the second season, scenes involving machines used rendered animations with cel shading, which upped the graphic quality immensely.
    • In the third season, the animation was outsourced to Korea and has less animation directors switching in-between episodes, making episodes look more higher-budget and consistent
  • The Anime of the Game: Sonic Adventure, its sequel, and Sonic Battle, while still taking liberties with the plot.
  • Antagonist in Mourning: When Sonic seems to be gone for good in "A New Start," Eggman takes the Egg Fort to the skies loudly and obnoxiously trying to find him, ostensibly so he can finally make sure he's dead and start his empire safely. When Sonic returns, Eggman is notably ecstatic even though he had just been thoroughly defeated, and gleefully goes off to plot his revenge, laughing all the way.
  • Anti-Villain: Dr. Eggman. Arguably more an Affably Evil villain early on, but by the third season, his role as true villain is all but gone.
  • Artistic License – Sports: Averted and played straight in the Baseball Episode. 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.
  • Ash Face: This happens to various characters at various times, usually whenever Bokkun delivers a (self-destructing) message/bomb.
  • Asleep for Days: Sonic after fighting Dark Oak for the first time, according to Eggman (in the dub, at least; he originally didn't specify how long Sonic had been lying there). He did take a plunge from the planet's upper atmosphere, after all.
  • As Long as It Sounds Foreign: If it wasn't important to the plot, signs in the background would have arbitrary Roman Letters written on them. They didn't even try to make them spell anything meaningful.
  • Bad Boss: Eggman at times, to the point Decoe and Bocoe did a brief Heel–Face Turn after too much abuse from the doctor. Granted however it's usually in a much more harmless and slapstick manner than, say, his SatAM counterpart. His minions also seem to be the nearest he has to actual friends (something which does show on occasion).
  • Baseball Episode: Episode 10 has Sonic and crew vs. Eggman's robot team with a Chaos Emerald at stake. To be fair, Knuckles did tell them it was a dumb idea... .
  • Bathtub Scene: Rouge the Bat twice (in episode 57 and 68). She takes her baths wearing her gloves.
  • Beach Episode:
    • Episode 9 with Amy Rose, in a swimsuit, that has a prominent focus in the episode.
    • 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.
  • Becoming the Mask: While a competent agent, Stuart seems much happier as a teacher, and even abandons his duties to protect the kids on occasion.
  • Belated Injury Realization: Sonic in episode 53 was comatose for a week in Eggman's base after a fight with Dark Oak and has a wound on his upper arm throughout the entirety of the episode. He hardly ever pays attention to it until Knuckles points it out to him.
  • Belly Dancer: 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.
  • Berserk Button:
    • For Cream, calling Cheese her pet. He's her friend.
    • Ella gets one in Episode 20 when Bokkun pulls a prank on her. This causes her to flip out, board the X-Cyclone, chase Bokkun to Eggman and let loose.
  • Big Bad: Dr. Eggman in the first two seasons and Dark Oak in the final season.
  • Big "NO!":
    • Chris' reaction when the Eggsterminator kicks Sonic into the water after delivering to him a No-Holds-Barred Beatdown, which Eggman tried to get it to stop doing.
    • Cosmo does this too in the original version when she remembers the time that Dark Oak called her "White Seed" before her escape from her sisters' and mother's exploding starship at the end of the sixth-to-last episode.
    • Amy's own reaction as well when Sonic gets eaten by Dark Oak at the end of the fourth-to-last episode.
  • Big "SHUT UP!": Episode 5 has Knuckles yelling this to Sonic after the latter continuously makes a mockery out of him.
  • Bittersweet Ending: 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 Sonic and friends getting ready to stop him. However, Cosmo's seed has begun to sprout.
  • Bizarre Sexual Dimorphism: Cosmo's Rage. Males look like brutish monsters, females look like cute monster girls. When entering Mover Mode/the Final Form, the former transform into huge Godzilla-esque monsters, while the latter become huge trees.
  • 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 death not being directly referred to.
  • Blackmail: In the Metarex saga, Rouge blackmails Bokkun into helping her with a locket containing a picture of Cream the Rabbit, whom he has a major crush on.
  • "Blind Idiot" Translation:
    • The translators somehow misinterpreted "Chaos Control" as being the name of Eggman's base in the first arc, rather than the name of the teleportation phenomenon induced by the Chaos Emeralds. This confused kids when the name was used to refer to the effect in later episodes. The error even carried over into the tie-in comics, even though Archie should have known better, having previously produced comic adaptations of games that featured Chaos Control.
    • Emerl's name being mistranslated as Emel or ML.
    • Earthia's name being mistranslated as Hertia. Then again, even in the original, it is pronounced as Ashia, so it's not unlikely that this caused some confusion.
    • In the Spanish dub, arguably the worst part was Sonic being incorrectly called a puercoespín (porcupine) rather than an erizo (hedgehog).
  • Breaking the Fourth Wall:
    • Not much in the dub, but plenty in the original, though even so much more frequently in the beginning of the show than towards the end. For example, in "Cruise Blues", Decoe and Bocoe explain that it took them two weeks to repair the EggFort because they weren't in the previous episode, though in the dub, it's because Decoe kept complaining. Also, after the EggFort 2's (very far away) transformation, Eggman gets calls from Sonic X viewers saying that they couldn't see it. Eggman then tells them to get bigger TVs. (This was changed in the dub to someone complaining through the phone that the EggFort 2 "isn't all that", and Eggman exclaims, "I'm getting an unlisted number!")
    • From the dub: "Kids, don't use Formula One race-cars to catch hedgehogs!" (The original line was just "Kids, don't stand on moving cars!")
    • In the dub of the episode where Eggman blocks out the sun and "helps" people by giving them Solar Balls, Eggman starts fantasizing about what it'd be like if he had his own TV show called "Eggman X". He even announces to the audience to stay tuned for next week's installment.
    • 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 improvised line by Chikao Ōtsuka, Eggman's Japanese voice actor, as in the original script Eggman didn't have any lines at this point.
    • Another one that made it into the dub, in "Countdown To Chaos" the military attacks Eggman with tanks copied off of his designs. As he rants about it, Decoe cheerfully holds up pictures of the robots in question from previous episodes for the audience.
    • The Chaotix crew do this all the time. In their first episode, they introduce themselves to the viewers, and then find out what's been happening in their absence by watching Sonic X on DVD, complete with arguing about whether or not to skip the opening. In Season 3, they complain about not getting enough screen time, with Charmy cheerfully saying "We're extras!" while Vector argues that they still have an important role in the show.
    • In episode 56 (called "Dr. Eggman Sansen!" in the original and "An Enemy in Need" in the dub), after being defeated by the Metarex Jumpee, Decoe and Bocoe lament that they're not the heroes of this episode.
  • Bring It: A couple of times, Sonic insults Eggman (or one of his mechs) by turning his back and smacking his own bottom.
  • But Now I Must Go: The first series finale, where our heroes have finally built a portal that will send them all home. But then Chris, in a moment which did not at all help his already shaky status in the fan-base pulls the plug on it before Sonic can get through. They say goodbye properly at the end of the episode, where it's implied that Sonic could have gotten home whenever he wanted to, but chose to stay with Chris.
  • Butt-Monkey:
    • Knuckles gets this a lot in later episodes, as do the Chaotix in most of their few appearances. Eggman and his cronies also often play this role in a villainous sense.
    • Members of Chaotix even become Butt-Monkeys to each other.
      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!"
  • The Cameo: Episode 48 features a Lost World where Chris, Decoe, and Bocoe are briefly chased by (a somewhat smaller and more bestial version of) Mothra, and later on the cast is attacked by Mogera, who chases Eggman, his 'bots, and Chris around before facing off against Sonic, Knuckles, and Rouge. A statue of Godzilla also makes a brief appearance.
  • Camping Episode: Episode 22 involves the cast going on a camping trip to watch wildlife. It ends up with Chris and friends discovering a Chao garden, and according to Tanaka, that garden was there when he was a kid.
  • Canon Foreigner: Much of the cast.
    • Chris Thorndyke, his family and friends, and much of the human cast have no counterpart in the games. The few human characters who have counterparts in Adventure 2 are the president, his secretary, a unnamed reporter, and the unseen G.U.N. agent who killed Maria. They don't resemble their game counterparts in appearance, and were Named by the Adaptation in Michael R., Christina Cooper, Scarlet Garcia, and Mister Schmitz.
    • Decoe, Bocoe, and Bokkun. Before Sonic Colors, Eggman wasn't know for having robot lackeys outside the Adventures of Sonic the Hedgehog cartoon.
    • Cosmo and the Metarex of season 3 have no game counterparts, and are strictly an anime-original creation.
  • Character Development:
    • As shown in Episode 20, the adventure seeker Sonic can't stand being confined to small spaces such as a cruise too many days. However, by the end of the episode, he learns to just relax and enjoy the moment. As a result, he's able to put up with being confined to the Blue Typhoon in the second series.
    • Toward the end of the first series, Chris learns to quit being so reliant on Sonic, and stop wallowing in angst. As a result of this (and the six year Time Skip), he's much more mature in the second series. This is easily seen at the beginning of this one, as he quickly gets over his self-pity over being weaker than Sonic and his friends and quickly finds an area he can help in.
    • As in the game the Chaos Saga was based on, Tails and Amy resolve to become more self-reliant and less dependent on Sonic toward the end of this one.
  • Cheated Angle:
    • Sonic always has 3 spines, no matter which angle you look at him from. Head on and from behind look very odd as a result of this.
    • Per the franchise's norm, anthros are depicted with side-mouths all the time.
  • Children Are Tender-Hearted: Cream is a Cheerful Child who is often concerned with others' safety. In "A Wild Win" in particular, Emerl has become violent from a Chaos Emerald's influence. Cream is worried that he's going to seriously hurt someone and is distraught that her friend has had such a drastic change in personality. When she has to fight him, she is clearly reluctant to do so. Soon, Cream is forced to kick Emerl into the water, which effectively kills him, and she and Cheese both sob over him.
  • Chuck Cunningham Syndrome: Despite being the first character to appear in the anime, Big the Cat only appears in the Adventure 1 adaptation and a minor cameo during the Battle adaptation. After the tournament, he never appears again.
  • Combining Mecha: Decoe and Bocoe, although the first occasion of this happening was subverted. Also, Eggman's ship, the EggFort 2, was actually three separate creations that also combine into the Eggsterminator (E-99 Egg Emperor), although the actual combination to the EggFort 2 was ridiculously zoomed out.
  • The Comically Serious:
    • Easily the most obvious reason Knuckles is something of a Butt-Monkey. You can literally gauge how badly a scene will go for him based on how humorless or stiffly he acts before things go south.
    • Espio is this too. Especially when he's with his 2 Chaotix team-mates, Vector and Charmy.
  • Comic-Book Time: The series lasts chronologically long enough for characters to have at least aged a year, as such the series avoids the issue of ages in the Metarex arc, being no longer shown on eyecatches.
  • The Complainer Is Always Wrong:
    • This seemed to become a running gag—a recurring situation would come in which Knuckles would object to a team mission plan, usually leading the gang to use peer pressure and goad his ego and bravery until he gave in. In the Metarex arc they instead just physically threatened him. This is despite that fact that the gang also spent a lot of time explaining to Knuckles how he shouldn't constantly fall for Eggman manipulating or tricking him into working for him.
    • 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 he believes in peace and that anyone is capable of good.
  • Composite Character:
    • Well, not really a character, but in this continuity, the Tornado 2 is a repainted and upgraded version of the original Tornado, rather than a separate plane.
    • Chris takes over several scenes originally belonging to Tails and Amy in the games. Most infamously, it's he who makes Shadow realise what Maria's true wishes were, prompting his Heel–Face Turn, whereas in the games, it's Amy who did that.
  • Conflict Ball:
    • Excused example in the "Sunblock Solution"/"Eggman for President" two-parter, where the public are quick to form an angry mob against Sonic's team after he is caught destroying Eggman's seemingly good-willed attempt to give the town artificial light. As it turns out though, Sonic had figured out the real plan; Eggman had in fact used his technology to brainwash the town into idolising him and turning on the heroes. While the main cast do begin to genuinely suspect Sonic, they catch themselves pretty quickly (and as Knuckles points out, Sonic didn't help his case by not bothering to tell anyone, and even trolling the attempts to stop him).
    • 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 several unfortunate misunderstandings where the Chaotix end up getting pummelled. It is only because Tails is zealous enough to try attack their ship post-retreat that they realise who it is and meekly apologise to the now beaten down Chaotix.
  • Construction Vehicle Rampage: In the episode "Chaos Emerald Chaos" during the construction scene, an excavator itself goes out of control after its bucket came into contact with the Chaos Emerald and goes on to flip a truck, scaring a confused construction workers including its operator. The machine eventually stops just as suddenly as it began.
  • Continuity Nod:
  • Cry into Chest: Tails weeps openly into Sonic's chest when he returns to the Blue Typhoon and reveals the only thing he could find left of Cosmo; A tiny white seed.
  • Cultural Translation: In the first Chaotix episode, Vector's references to Case Closed are changed in the dub to references to Sherlock Holmes and Columbo — and yet, the dub edits the cigar out of Vector's hand, which would have strongly accentuated the reference.
  • Curb-Stomp Battle: Super Sonic dished these out frequently (most notably against Perfect Chaos). Dark Oak made his malice known by being the one Worthy Opponent Sonic's super form had in the anime.
  • Curb Stomp Cushion:
    • Commonly happened against Sonic due to being The Juggernaut. Enemies could knock Sonic down a few times, only for him to recover and quickly leave the threat in scraps. The Chaos 6 fight is a good example - Sonic is initially pinned down and struggles to fight it, but as soon as Knuckles arrives and frees him, he takes Chaos 6 out in one hit.
    • Shadow vs Tails. Even though he couldn't stop Shadow, Tails's cleverness and quick thinking allowed him to eject Shadow out of the ship by shooting him out with the Sonic Driver cannon.
  • Cute Monster Girl: Cosmo and the female members of her race, especially by comparison to their large, brutish male counterparts.
  • Darker and Edgier: Season 3. Especially the last episode.
  • Deliberately Cute Child: Cream, though usually genuinely innocent, is suggested to exploit this trait a couple odd occasions, perhaps most triumphantly against one of Eggman's sentient mooks in a baseball game.
  • Demoted to Extra:
    • In the game adaptations, the Egg Viper, the final boss of Sonic's story and one of the most popular boss battles of the series, has about one minute of screen time, while the Egg Walker, Tails' final boss battle, doesn't even appear.
  • Depending on the Artist: 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 here
  • Desperate Object Catch: In episode 17, two characters are desperately trying to catch "Chaos" which is falling from great height. Both parties impede each other so the gem falls in the hands of a bystander instead.
  • Destroying a Punching Bag: In the episode "The Adventure Of Knuckles & Hawk", after escaping a landslide from the night previous, Knuckles is so incensed at losing the chaos emerald in the landslide that he takes his anger out on a punching bag. Punching it so hard that the whole things and the wooden beams supporting the punching bag comes crashing down onto Knuckles making a mess.
  • Diabolus ex Nihilo: E-105 Zeta. In Sonic Adventure, he appears along with the other E-100 Series robots when they are tasked to capture Froggy. In the anime, he doesn't appear until Gamma goes to the Hot Shelter in "Revenge of the Robot", and even then Zeta's appearance was too brief to make any lasting impressions.
  • Diegetic Soundtrack Usage: On a few occasions, Eggman hums, and even SINGS, his leitmotif.
  • Disproportionate Retribution: In the first season finale, Rouge gives Knuckles the mother of all No Holds Barred Beatdowns after annoying her with his self absorbed whining. It shortly degrades into more playful fighting however.
  • Don't Try This at Home: In episode 1, Sonic jumps on top of an S-Team race car during a chase, causing the driver to protest that they don't want any kids copying him. In the Japanese version, Sonic duly warns the kids in the audience never to stand on moving cars. The dub parodies this: Sonic instead tells them not to chase hedgehogs with F-1 race cars.
  • Double Standard: Abuse, Female on Male: Amy's behaviour to her unwilling crush (and later nearly everyone else) leans into this (Eggman scoffs at the likes of Sonic constantly but is amusingly terrified of Amy and her mallet). Knuckles has also faced heavy verbal and physical abuse from almost every female cast member at least once in the series (and yes, that's including Cream and Cosmo).
  • Dramedy: The series sinewaves between slapstick, almost Looney Tunes-style comedy and dead-serious, somber sequences.
  • Dub-Induced Plot Hole:
    • In Episode 16, Chris twice holds up a sign telling good kids not to attempt his latest scheme. Sonic also holds up a sign sarcastically asking if he's saying Sonic isn't a good kid. TMS blanked out the signs for the US masters, making it look very awkward as Sonic and Chris are standing there holding up blank signs to the audience.
    • There are plenty of these throughout the series, for instance, TMS blanking out Vector's name on the handkerchief that Tails picks up in a series 3 episode (itself a scheme to try to hook Cosmo up with Tails by having him pick her handkerchief up, a plot point 4Kids also cut out).
    • Due to a goof, Eggman's base in the New World Saga is called "Chaos Control" in the dub and the comic based on it. This causes issues in later episodes when the term is used for the phenomenon induced by the Chaos Emeralds.
    • An infamous one was Sonic seemingly ignoring Tails when he was crying into his chest over Cosmo's death, rather than comforting him. In the Japanese original, Tails was instead blaming Sonic for not rescuing Cosmo and hitting his chest, so Sonic simply let him vent on him without saying anything so as to not make things worse. The dub left this out, making Sonic look oddly cold and insensitive.
  • Dub Name Change:
    • Lucas to Luke.
    • E-99 Egg Emperor to E-99 Eggsterminator.
    • Emerl became Emel (or possibly ML) in the dub.
    • Earthia to Hertia.
    • The Latin American dub translates the names of the Sonic characters to Spanish, with the exception of Sonic and Big. All of them are literal translations except for Eggman, who is renamed "Doctor Huevo" (Doctor Egg). The Metarex likewise get renamed.
  • Dub Species Change: The Latin American Spanish dub of the show refers to Sonic as a porcupine.
  • Dying as Yourself: When Emerl dies he sheds tears as he sinks into the ocean (oil in the original Japanese version)
  • Early-Bird Cameo: Rouge and Big appear in the first episode. Rouge is introduced eleven episodes later, and Big has to wait two story arcs.
  • Eating the Enemy: During the final battle with Metarex, the Big Bad Dark Oak is able to amass the Chaos Emeralds and use them to fuse with his commanders to become a One-Winged Angel plant dragon. Eventually, he gives Sonic an offer that We Can Rule Together, but Sonic naturally declines. His response is having a burst of water sending the hedgehog flying down his throat. The gang are able to save him later though.
  • Enemy Mine: Frequently Eggman ends up working with Sonic after another more dangerous foe becomes a threat to them both.
  • Ensemble Dark Horse: In-Universe example with Knuckles, despite his frequent role as the team's Butt-Monkey and embitterment about Sonic's endless popularity, he is in fact revealed to have a large base of fans around the world (something the others exploit to coax him into a promotional Battle Tournament).
  • Even Evil Has Standards: 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".
  • The Everyman: As a young human boy unwittingly dragged into Sonic's adventures, Chris is intended to be this - and like many an Everyman, possessed a 'neutral' personality.
  • Eyelid Pull Taunt: In Episode 3, Sonic does this while standing on Missile Wrist's arm, in order to goad it into hitting itself. Some versions of the 4Kids dub omit this scene, while others leave it in.
  • Falling into His Arms: Happens on a few occasions with Chris and at least once or twice with Amy, Cream, and Cosmo.
  • Family-Friendly Firearms:
    • In the 4Kids dub, the guns fire lasers instead of bullets. The strangest thing is, they still look EXACTLY like guns, complete with visible shell casings being ejected. It's just the sound effects that changed.
    • On occasion, this actually made more sense than the Japanese sound effects, however. In a reverse situation to the dub for example, E-102 Gamma's laser fire makes bullet fire noises in certain episodes of the original edit, while the dub sounds more accurate with its usual laser noises.
  • 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
  • Filling the Silence: The English dub adds dialogue in several silent moments. Gamma's arc in particular suffers from this, especially when you compare it to the original game: his letting Amy go, his discovery of the partially-disassembled Beta, and his Mutual Kill of Beta are all far less impactful thanks to Gamma screeching his way through them.
  • Five-Token Band: Well, four. Chris' circle of friends managed to fit in one black kid, one tomboy, and one disabled kid.
  • Flanderization:
    • While Amy still had occasional Tsundere mood swings in the games, she was still a genuinely high-spirited and kind-natured girl. This element of her persona eclipsed her character until she became a Bratty Half-Pint that the cast was either irritated by or outright terrified of.
    • As in the games, Knuckles was originally calm and collected if a bit gruff, though the anime gave him a bit of a temper that would occasionally surface. Then as the series went on and especially after joining Sonic's crew, he became more hot-headed and dim-witted as well as an occasional Butt-Monkey of the group.
  • Foreshadowing:
    • At the end of Episode 17, Knuckles receives a brief flashback from Tikal, courtesy of the Chaos Emerald he's just received.
    • 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 Sonic Adventure 2.
      [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.
    • Also, in one of the last episodes:
      Chris: If [Sonic] can survive, then we can too! Isn't that right, Cosmo?
      [Cosmo doesn't say a word]
    • The plant-based names of Dark Oak and the Metarex Bosses foreshadow the fact that they're plant beings and are related to Cosmo.
  • Foul Flower: While most of the villainous Metarex are named after trees, there is one named Black Narcissus. He is one of the most cruel Metarex, willing to hurt Chris, and, as his name indicates, very self-absorbed.
  • Four Lines, All Waiting: Episode 39 juggles three different plotlines: one in which the government becomes concerned about the increasing number of creatures being transported from Sonic's world and decides to segregate them; one in which Eggman expresses remorse for his actions in the previous arc and offers to repair the moon; and one in which the newly-arrived Team Chaotix set out to track down Cream, who they believe has been kidnapped by Sonic.
  • Freeze Sneeze: Sonic does this after jumping into the ocean to save Amy, presumably due to getting soaked.
  • Friendly Tickle Torture: During the season finale of the 2nd Season, after Rouge and Knuckles get into a fight, upon seeing Sonic has returned Knuckles cracks a joke on Rouge's ruffled appearance, leading Rouge to do you know what... offscreen.
  • Friendship Denial: In a couple of episodes of the first season, especially in "Cracking Knuckles", Knuckles would blatantly deny being friends with Sonic, but this is due to his irritation of Sonic's attitude and recklessness.
  • General Ripper: One, appropriately named Colonel Basher in the English dub, serves as the villain of Episode 50. Believing that Eggman is planning One Last Dance before being transported back to his home dimension, and that the President is too much of a "peacenik" to respond, Basher orders an all-out robotic assault on Eggman's HQ and has his men blockade the White House so that the President can't interfere. Sonic fends off the attack long enough for Eggman to assemble the Grand Egg Imperial and destroy the attacking forces, while Knuckles and Rouge break into the White House to rescue the President, and Basher is ultimately arrested.
  • Genre Savvy: The Chaotix, despite their occasional incompetence, are very savvy. It's even more prominent in the Japanese version, where they constantly break the fourth wall.
    Espio: Change the scene and suddenly you know where Sonic is. Is it just because the program's almost over?
  • Good is Not Nice:
    • Despite being one of the good guys, Knuckles has a very short temper and is prone to punching someone anytime they insult him or make a sarcastic remark. Other than that, he can be relatively friendly when he's in a good mood.
    • Amy is hostile, violent, loud and aggressively overprotective, especially in the Metarex saga.
    • Shadow after his Heel–Face Turn. The extremity of some of his efforts borders out and out villainous on occasion. Not to mention that he's very cold, violent, and uncaring.
  • Hair-Trigger Temper: Amy, especially as the series went on. Knuckles in a couple episodes as well, though usually he has more of a slow temper that is very easy to rekindle once it gets going.
  • Hand Wave: The premise of Sonic and co being transported to a different world made the adaptation of Sonic Adventure 2 problematic, as the game's plot revolves around a decades-old government conspiracy and a space station. To explain this away, when Eggman reads his grandfather's diary, he concludes that Earth is the world he was originally born on. This plot point is never expanded on, so we never find out how Eggman came to be on Sonic's world, why the Eclipse Cannon is powered by artifacts from a different dimension, or why Project Shadow resulted in the creation of a humanoid hedgehog.
  • Happy Ending Override: Not overall, but the end of Season 2 - which was supposed to be the series' ending - seems to imply Sonic and Amy will get together, same with Knuckles and Rouge, as both pairs. In the next season, neither of these parties is a couple, nor do they become one.
  • Harmless Villain: Eggman as time passed became less and less effective as a villain (though granted Sonic's own Invincible Hero qualities didn't help). Curiously, however, the doctor had Laser-Guided Karma on his side and his savviness and competance increased much more on the odd occasion he was working on the side of good.
  • Heel–Face Turn: Decoe and Bocoe after repeated mistreatment from Eggman (and being shown empathy from the heroes) briefly turn side, acting as butlers of sorts for Chris. It lasts only two episodes with them rejoining Eggman to assist in preventing the spacetime destruction formed from Earth and Sonic's world merging (along with the subtle implication that Eggman actually misses them).
  • Hero with Bad Publicity: For the first several episodes of Season One, Sonic and his pals were on the run from the authorities and spent most of their time hiding out in Chris's house when not foiling Eggman's latest scheme.
  • Heroic BSoD: Cosmo shows an interesting case near the end of Season Three. In the sixth-to-last episode, "Shadow's Arrival" / "The Cosmo Conspiracy", Dark Oak congratulates her for a job well done in helping him collect all the Chaos Emeralds at the end of the episode, that while calling her by her codename of "White Seed" that he gave her just before her escape from her sister's starship before its destruction. This causes Cosmo to remember the time that Dark Oak gave her the codename of White Seed, right before letting loose her Big "NO!" (in the dub, she just let loose a wailing scream). And then, in "The Lost Planet" / "Eye Spy", Cosmo is tossing and turning in bed in frustration with tears in her eyes knowing that she was secretly working as an unwilling spy for the Metarex, refusing to be anybody's friend just because of said knowledge and telling everybody to stay away from her. Before she can go to confront Dark Oak alone, she is stopped by Tails, and it takes his kind words and that of everyone else together for her to get better.
  • Heroic Sacrifice: Cosmo performs this in the second-to-last episode of the second series to help Sonic and friends defeat Dark Oak.
  • Holding Your Shoulder Means Injury: Sonic tends to do this quite a bit when left worse-for-wear. Chris also does it in Episode 38 after Shadow attacks him (though the dub actually cuts out the attack itself, making it look like Chris just got tired somehow).
  • Homage: The entire third season is a massive tribute to Space Battleship Yamato, something that wouldn't be obvious to 4Kids' target audiences when first aired, which makes its cancellation in Japan somewhat more tragic.
  • Hope Spot: When Emerl's eyes turn back to blue, Cream and Cheese are happy to see him turn back to normal, only for his eyes to turn orange again and his aggressive behavior to immediately return.
  • I Warned You: Often issued to Knuckles each time his truce with Eggman turns out to be a trick. Interestingly Knuckles never uses the trope the several occasions the team's plans go haywire (as he sometimes predicts, and is ignored), something that can be considered somewhat out of character for him.
  • Head Desk: A rare non comedic example. Tails head desks when he's forced to shot Cosmo.
  • Imagine Spot: In episode 44, Mr. Stuart is imagined doing a Bond Gun Barrel and Sean Connery Is About to Shoot You, creating a crack and hole at the camera screen.
  • Innocent Plant Children: Cosmo is a child-like tree who is very innocent and friendly to those she meets, especially Tails. However, this gets darker when it turns out that she was once the same species as the Metarex, a power hungry robotic faction that destroyed her homeworld, while their leader Dark Oak had Cosmo acting as an unwitting spy.
  • Interspecies Romance: Inter-kingdom, actually: Tails and Cosmo.
  • Invincible Hero: Sonic on occasion really leans into this trope. The majority of times he beats Eggman and other villains rather handily and generally treats the whole thing as a fun little game. Shadow leans even further into this (and its villainous twin earlier on): Sonic at least had problems with the Metarex, even in his Super form, Shadow on the other hand beat an entire army of them in one swoop.
  • Jerk with a Heart of Gold: Just a number of these characters are this:
    • While not technically a jerk, Knuckles has a temper, and can be a bit blunt and abrasive, but he can be nice guy when in a good mood and is loyal to his friends.
    • Amy behaves in an aggressive and intolerant manner and can be a Bratty Half-Pint at times, but she gets heroic when the times are right.
    • Rouge may be selfish and greedy at times, but she cares about Topaz and the others.
    • Despite being mostly cold and aloof, Shadow shows his soft side on occasions.
  • Knight of Cerebus: The Metarex, especially Dark Oak, are established as much more demonic and powerful villains than Sonic has ever faced before, giving the usually Invincible Hero Sonic a hard time even in his super form. That being said, how much each individual Metarex counts as this trope varies; they range from the Laughably Evil Yellow Zelkova, to the emotionless Pale Bay Leaf, to even the Tragic Villain Magnificent Bastard Dark Oak himself.
  • Lampshade Hanging:
    • "I see you have a brain, so why don't you use it?"
    • 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 Aside Glance is cast.
    • In the dub of one episode, after Rouge steals a Chaos Emerald Sonic and co. had, Amy shouts, "She's stolen the Chaos Emerald!" Knuckles sarcastically replies, "Thanks very much for the update!"
  • Large Ham: Shadow, Knuckles, and Chris's uncle, Sam Speed.
  • Late-Arrival Spoiler: Sort of. In Sonic Adventure 2, the fact that Rouge is a government spy and is double-crossing Eggman is a major plot twist. Sonic X, however, establishes this long before that arc even begins.
  • Leaning on the Fourth Wall: When Topaz asks her commander why Rouge gets all the glory for infiltrating Eggman's base, he responds that in some shows you just can't help being a bit player.
  • Leitmotif: To an egregious extent in the dub, where a character's leitmotif will play almost every time they open their mouth, even if it's just for two seconds. Depending on who's speaking, this can result in the Background Music shifting back and forth between genres extremely rapidly.
  • Limited Animation:
    • It's even more obvious here in this show than it is in most anime. However, the show was produced on a much smaller budget, mostly due in part to Sonic's general lack of popularity in Japan compared to the West.
    • 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.
  • Literal-Minded: 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 disperses confetti and activates robot cheerleaders that flatly cheer "hip hip hooray!" Bocoe Face Palms 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.
  • Love Redeems: Following Cosmo's sacrifice, Luke/Lucas reappears, reformed and repentant, realizing the errors of his ways as Dark Oak and the fact that his lust for power destroyed his own people and only brought pain and suffering to the universe. A vision of Hertia/Earthia appears before him and gives him a second chance, redeeming him, after which then he happily reunites with Hertia and they both depart for the afterlife.
  • Magic Skirt: Cosmo. Also Cream and Amy. Although Amy's skirt acts as if it might have a wire frame keeping it in place. Which is a real thing, although unusual for a skirt so short.
  • Mascots Love Sugar: Bokkun at one point goes against his instructions and helps the heroes twice, with the promise of getting apple pie and strawberry cake as a reward for his efforts. More than a bit odd considering that he's a robot, but there you go.
  • Mass Hypnosis: Eggman pulls off a particularly convoluted one during the "Egg Moon" three-parter. After a "glitch" causes the Egg Moon to perpetually block the sun, Eggman apologises and offers to sell the public his newly-invented "sunshine balls" as a temporary solution. It turns out that, as well as emitting heat and light, the sunshine balls also emit subliminal messages, compelling people to worship Eggman and hate Sonic.
  • Mecha-Mooks: Decoe and Bocoe mostly cater to Eggman's every whim, while Bokkun acts as his messenger.
  • Men Don't Cry: When Sonic leaves Chris' world at the end of Episode 52, you can tell that he's crying, you just can't see his eyes.
  • Minion with an F in Evil: Decoe and Bocoe, despite being loyal to Eggman, are meek cowardly droids that resent some of their more callous orders from the doctor (in the anime's Sonic Adventure adaption for example, they are charged with disposing of the more incompetent E-100 Series models) and actually enjoy doing kindly deeds for people. They actually show enthusiasm when the doctor appears to turn a new leaf, only for it to usually be revealed as a another scam. That said, it helped that by the final season Eggman himself had essentially became a Big Bad With An F In Evil.
  • Monster of the Week:
    • The first 26 episodes used the show-exclusive E-Series robots in this role. After this, the show decides to adapt the videogames.
    • The Metarex saga from season 3 has Sonic and friends going to space, and fighting members of the Metarex almost every episode to stop them from conquering the universe.
  • Mood Whiplash: Perhaps one of the most emphasised examples in most forms of Sonic media. Comparing the cartoony, harmless fun of the first few episodes to the somewhat grim finale certainly shows an uneasy shift in tone.
    • Episode 38 is the show's adaptation of Sonic Adventure 2's Last Story, one of the darkest and most tear-jerking finales in the franchise's entire history. Episode 39 is the wacky, fourth-wall-breaking debut of the Chaotix. If you're watching them back-to-back, it's extremely jarring.
    • In a scene played for laughs, Charmy bawls his eyes out. Vector told him to stop crying then Charmy immediately stopped with a grin.
  • Mourning a Dead Robot: Cream and Cheese bawl loudly after being forced to kill their friend Emerl.
  • Mutual Kill: The deaths of Gamma and Beta are depicted in this way, with the pair fatally wounding each other at the same time, though Gamma manages to survive long enough to acknowledge the completion of its mission. In the games, by contrast, it's a Last Breath Bullet scenario.
  • Mythology Gag:
    • The first episode has Sonic speaking directly to the kids watching, telling them Don't Try This at Home, which is very reminiscent of "Sonic Sez".
    • 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 Sonic R.
    • Sonic has an extreme fear of water. In fact, when he falls into a pool in the first episode, he has trouble escaping, complete with a version of the drowning music from the games in a different key.
    • 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 Sonic Heroes.
    • In Season 3, an adult Chris is showing Helen some new devices he invented to help Sonic out. Two of the devices he mentions by name are Speed Shoes and Magnet Barrier, referencing the items of the same name from the classic Sonic games (and Chris's description of what they do matches what they do in the games, in addition to their designs in the sketches shown in the episode matching what they look like in-game). His other invention, Ring Road, creates a path of giant rings that Sonic travels down, much like a certain device in Death Egg Zone in Sonic 3 & Knuckles and also bringing to mind the Light Speed Dash.
    • The famous scene from the OVA in which Sonic attempts to rescue Metal Sonic from lava is recreated in Episode 72, with Knuckles and Yellow Zelkova taking their places.
    • Cosmo seems to be loosely based on Lumina Flowlight.
  • Named by the Adaptation:
    • The bird Amy rescues in Adventure is never named in the original game, but is named "Lily" in the anime's adaptation of it.
    • The English dub gives the name "Galaxina" to Cosmo's older sister, who went unnamed in the original Japanese version.
    • The English dub also names the husband of minor character Daisy "Landar".
  • Never Say "Die": The dub, being a 4Kids dub, naturally has a few examples:
    • Gerald says Maria was "taken away" and "lost" instead of killed. Close examination of the dialogue, such as both Shadow and Gerald referring to her in past tense, reveal clearly the dub meant she was killed but without directly using the word.
    • After Sonic and Shadow first clash, in the Japanese version, Shadow brags that if he hadn't held back, he would have killed Sonic. In the dub, he merely says Sonic would have been "much worse off".
  • Nice Guy: 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 Adventure games.
  • Nobody Calls Me "Chicken"!: Knuckles can often be swayed into a plan he initially shows disapproval or disinterest in by stroking or insulting his pride. At times this is exploited to ludicrous lengths by friends or foes alike.
  • No Fourth Wall: Frequently, usually Sonic himself, but occasionally Rouge and once Chris as well. Mostly averted in the dub version, with the exception of the first episode.
    Kids, don't use Formula 1 race cars to chase hedgehogs!
  • Non-Mammal Mammaries: Cosmo gains breasts upon entering Super Mode in the climax of the Metarex arc. The Japanese version has the most gratuitous shots of them, of course.
  • Oh, Crap!: Eggman gets this quite often, like when he's about to get smacked by a pissed-off Amy in Episode 9, and when his E-18 Guerra-Hard robot is about to explode after Sonic overpowers it thanks to the two Chaos Emeralds he snatched from it in Episode 13.
  • Once More, with Clarity!: A minor example. Episode 51 begins with a lengthy recap of the end of Episode 50, but adds Chris' internal monologue, revealing that he isn't as willing to part ways as he lets on and making his subsequent actions seem almost premeditated.
  • Only Sane Man: In the episodes "Sunblock Solution" and "Eggman for President", Eggman pulls a gambit to make people believe that his new "Egg Moon" has malfunctioned and is blocking the sun, making himself a Villain with Good Publicity by producing Mirror Towers and Sunshine Balls to provide light while he fixes it. Sonic is the only person to realize right off the bat that Eggman is deliberately placing the Egg Moon in front of the sun because if it had really stopped in orbit, it would just stay in place while the Earth continued to move. Unfortunately, Sonic don't quite realise he's the Only Sane Man, and is genuinely surprised when first Knuckles, and then the government, try to stop him from destroying the Mirror Towers.
  • Plot Hole: In the Sonic Adventure 2 arc, it's revealed that Eggman and his family were born in Chris's world and for an unexplained reason Eggman ended up in Sonic's world. Come the Homebound arc where Sonic and the rest of the inhabitants from his world must return home to prevent their worlds from merging and freezing time forever, and that includes Eggman despite him not being a habitant from Sonic's world.
  • Poor Communication Kills: Sonic refusing to tell anyone why he's destroying Eggman's Mirror Towers causes the government and Knuckles to spend an episode and a half chasing after him, as they think he's condemning the planet to eternal darkness. Even Tails and Amy are concerned about his actions before deciding to trust him. In Sonic's defence, he thought it was obvious that Eggman that was up to something and was genuinely surprised that nobody else realised (to say nothing of the fact that the Sunshine Balls had been hypnotising everyone to worship Eggman).
  • Precision F-Strike:
    • Sonic in the Japanese dub of Episode 2, right in front of Cream.
    Sonic: 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!".
  • Previously on…:
    • In the Japanese version of Episode 39, Charmy gets a Sonic X DVD, and Vector tries to play it on a film projector. Espio then "borrows" a DVD player from a convenience store and the Chaotix watch a montage of footage from the previous episodes. Perhaps because of Espio stealing a DVD player, this entire scene is cut from the dub, so a longer montage was added to the scene where Vector reads the newspaper to pad out the missing time.
    • The dub does this in every episode anyway:
      Narrator: Last time on Sonic X...
  • "The Reason You Suck" Speech: Also counts as Jerkass Has a Point. Eggman gives this one out to Chris when he thinks he's lying about not being responsible for the world put to a time freeze.
    Eggman: You're the one who's lying to yourself. You don't wanna accept the truth. Deep down, you know once Sonic is gone, your life will have to go back to the way it was before. Your days of adventure are at an end, boy, just like your friendship with that hyper-annoying hedgehog. All your dreams have been shattered, haven't they? Life is like that, kiddo. Take it from somebody who knows! Whenever you reach too high, life smacks you down! But on the bright side, at least you and I won't have to see each other ever again.
  • Red Stapler: In-Universe, all the footage and news coverage of Sonic has a lot of humans copy some of his habits such as taking naps on rooftops, running around as fast as they can and dying their hair blue to resemble the quills on his head (as shown is episodes 42 and 43).
  • Reformed, but Not Tamed: 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 own title game).
  • Robo Speak: Decoe and Bocoe talk like this in early episodes of the dub (though gradually become more emotional as the series progresses). Interestingly both language versions give E-102 Gamma this dialect (in comparison to his mellow Machine Monotone in the games).
  • Sarcastic Confession: Eggman in episode 49.
    Eggman: You figured out my scheme, kid. I despised Sonic so much I decided to 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.
  • Self-Punishment Over Failure: In Episode 21,a sumo-themed robot launches itself into the distance after failing to stop Sonic. It ends up crashing into Egg Fort II.
  • Series Fauxnale: The end of Season 2, which is understandable given it was originally supposed to be the end of the series before an unexpected order for more episodes. All the characters from Sonic's universe have to return to their world. After initial resistance, Chris and Sonic have a heartfelt goodbye. Sonic then stops Eggman from conquering his world, with his archenemy ecstatic to have him back. Additionally, the ending seems to hint at the pairings of Sonic/Amy and Knuckles/Rouge actually getting together, which isn't the case in Season 3. The only real tag for another season is the ending where it's revealed Chris is working on a portal to meet Sonic again.
  • Sexy Discretion Shot: In one episode, Knuckles and Rouge have a fight over Sonic. When they see he's alright, Knuckles points out that Rouge looks awful with dirt on her face. Rouge responds with "oh yeah?" and tackles him. The camera cuts away to the moon in the sky, while Knuckles is heard laughing and Rouge is heard tickling him (kissing him in the Japanese version).
  • Sexophone: A leitmotif for Rouge.
  • She's a Man in Japan:
    • Cheese is called "she" and "her" in the English dub.
    • The Italian dub turns Charmy into a girl.
  • Shipper on Deck: Amy is probably the one who made Cosmo realize she had feelings for Tails in the 3rd season when she remarks that the two seem cute together. Team Chaotix tries to actively ship the two in a later episode; though all of their attempts fail Tails and Cosmo still sort of get together on their own (it's never really absolutely official until Cosmo is killed).
  • Ship Tease:
    • Sonic and Amy. Especially in the last episode of the first series, where Amy pours her heart out telling Sonic how she was ready to wait forever for him, and insists he admits he loves her. Sonic's reply is inaudible (in the Japanese version, at least, but judging by Amy's reaction, whatever he said, it wasn't "no").
    • Knuckles and Rouge have plenty of moments together and Rouge tends to flirt with Knuckles. Their last scene in Season 2 is noticeably rather intimate, and the Japanese version has Rouge kissing Knuckles offscreen.
  • Shoot the Dog: Cream knew there was no hope for Emerl, so she was reluctantly forced to kill him so he wouldn't hurt anyone else.
  • Shout-Out: A few examples;
    • The Egg-Fort 2 resembles the Enterprise from Star Trek.
    • In episode 39, Vector makes a spoof of Case Closed by saying that he has "the brains of a genius and the appearance of a crocodile." He even has the glasses, hairstyle, and tone of voice to boot. Charmy remarks that he was watching the anime channel until morning. The dub converts this to impersonations of Sherlock Holmes and Columbo (the similar jacket and mannerisms make the latter a rather swift transition).
    • Eggman's two-Chaos-Emerald-powered mecha is Mazinger Z.
    • The X-Cyclone has a Gerwalk mode.
    • Several of the shoes Chris makes for Sonic are based on shoe power-ups from the video games.
    • Eggman's mecha include Thunderbird 2, Great Mazinger, and the USS Enterprise.
    • From the same episode as E-90 Super Sweeper (aka Thunderbird 2), the launch sequence for the new X-Tornado (the collapsible palm trees) is also a shout-out to Thunderbird 2's launch sequence from the same series.
    • Mothra and MOGUERA appear in Episode 48 on a mysterious island. Mothra's a bit more vicious-looking and antagonistic (a nod to her dark twin Battra) and MOGUERA is based on his Showa appearance and battles Sonic, Knuckles and Rouge at the climax of the episode. Godzilla also appears as a statue that Bokkun sits on for a minute before it crumbles apart when MOGUERA appears.
    • Decoe and Bocoe are based on Omega and Epsilon from Kinkyū Hasshin Saver Kids, and possibly Scratch and Grounder from the Adventures of Sonic the Hedgehog cartoon.
  • Sliding Scale of Adaptation Modification: The series is largely Type 3 (Pragmatic Adaptation), though the Sonic Adventure Series based story arcs could go up to a 4 (Near Identical Adaptation).
  • Spared by the Adaptation: Molly in Season 3 of the English dub. Instead of making a Heroic Sacrifice like in the Japanese version, or invoking Never Say "Die" as with Maria's death in the dub, she simply "flies her ship into space to help other planets to fight the Metarex". 4Kids went as far as airbrushing out the cross on her grave when Shadow visits it, so instead, Shadow is just standing there.
  • Standard Bleeding Spots: Contains a few examples:
    • Rouge bleeds from the cheek when Knuckles slashes her there during the SA2 saga.
    • Sonic appears to have a wound on his upper arm in the first episode of the Metarex saga courtesy of Dark Oak.
    • Shadow gets a cut at the side of one of his eyes after he accidentally crashes into a solid metal door inside the Blue Typhoon whilst pursuing Tails and Cosmo.
  • Stock Footage: Very noticeable when Knuckles and Sonic first fight Chaos together.
  • Stop Drowning and Stand Up: When Sonic lands in a pond during a fight with Knuckles in episode 5, he instantly starts flailing and yelling in terror as if drowning. That is, until he realizes the water he's landed in is only a few inches deep.
  • Storefront Television Display: During Dr. Eggman's first attack on Station Square, he hijacks every TV screen in the city to broadcast his Take Over the World plans, and there's a brief shot of some passersby watching the message in a storefront display. Later, Sonic learns about the attack after noticing a crowd of people watching a similar display and taking a peek over their shoulders.
  • Surprisingly Realistic Outcome: When Eggman tries to conquer the town, he faces his first big difficulty: neither the policemen, their chief, or the mayor have the authority to officially surrender it to him.
  • Suspiciously Specific Denial:
    Bokkun: It wasn't me who put sleeping powder in your hot chocolate!
  • This Cannot Be!:
    • Yellow Zelkova's reaction to seeing the columns that were obstructing the Blue Typhoon's path tumbling to the ground after Sonic and co. defeat him for the first time with the Sonic Driver, (which, of course, he survives, making him the first Metarex to survive a blast from the Sonic Driver itself) while at the same time beginning the trigger for the tumble of said columns.
    • This is also Amy's reaction to when Serpenter crushes her lucky bracelet made for Sonic by herself in a much earlier episode.
  • This Explains So Much: Sonic says this in Episode 74 after a hologram of Hertia/Earthia relates a story to Amy and Rouge about how Greengate got destroyed and how the Metarex were born.
  • This Is Not a Drill: In episode 33, when Dr. Eggman breaks into Prison Island, a tannoy announcement says this almost verbatim.
  • This Is Unforgivable!:
    • In Episode 9, this is Amy's reaction to Serpenter crushing the "good-luck" charm she had made for Sonic. She flies into an Unstoppable Rage and proceeds to single-handedly (and literally) take Serpenter apart.
    • This is also what Sonic himself says to Eggman at the end of the finale of the third season in the original version, which in the dub was replaced by the line of "Life never stays slow for long. Thank goodness! Watch out Eggman! I'm coming at ya full speed!"
  • Time Bomb: The missile Eggman fires into Station Square during the Adventure arc is depicted as one, unlike the game where it's just a regular missile that fails to detonate on impact. Unlike most examples of the trope, it has no countdown timer, with Bokkun instead counting down the seconds out loud; and again, unlike most examples, he's still at about 30 when Tails defuses the bomb.
  • Took a Level in Jerkass: Amy to an extent as the series progressed (the games version went through a similar evolution at this time though not to the same lengths).
  • Through a Face Full of Fur:
    • Tails blushes at one point when he carries Cosmo up to the ceiling by means of his helicopter tails in order to decorate a room for a party. Tails blushes a lot during the latter half of season 3 around Cosmo, really.
    • Even if it's metal plating, Emerl fits this trope too in episode 46.
  • Tragic Keepsake: In the series finale, Tails receives what's left of Cosmo in the form of a seed from Sonic after both he and Super Shadow attempted to save her with their Chaos Regeneration. Tails later cultivates this seed in a plant pot inside his workshop where at the very end of the episode it is seen sprouting.
  • Treasure Is Bigger in Fiction: Averted. The largest gem in the world, as seen when Rouge steals it, is only the size of a particularly large fist.
  • Truer to the Text: 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 Sonic Adventure, Sonic Adventure 2 and to a lesser extent Sonic Battle).
  • Unflattering ID Photo: When Sonic and the gang were given passports in the episode "Depths of Danger", Amy's photo has her angrily wielding her hammer, and needless to say, Amy was not happy.
  • Vitriolic Best Buds: Sonic and Knuckles, just like in the games. Knuckles and Amy often have this chemistry with a few teammates due to their brashness (especially each other).
  • Vocal Evolution:
    • Decoe and Bocoe's voices in the dub initially are acted in a monotone Robo Speak. While the voices themselves remain the same for the most part, as the show progresses the acting for both gradually fluctuates to sound more emotional and human-like akin to their Japanese counterparts.
    • The cast for characters established for the games also slowly refine to sound more like the original games VAs (though the difference would only really come to show in later games titles for which the 4Kids cast provided voices).
    • Cream's voice in the dub becomes progressively higher and squeakier until, by the end of the series, it's reached levels that pretty much only a dog can hear.
  • Waking Up Elsewhere: Sonic awakens after his fight with Dark Oak to find himself on a bed inside Dr Eggman's base. Turned out that the good doctor saved him from almost certain death and allowed him to recover his health during the time that he was comatose.
  • Wasn't That Fun?: Helen goes on a wild ride with Sonic in Episode 14 that takes them to and across an island in the middle of a lake where Helen says there is a beautiful patch of white flowers. The two are being chased by government troopers trying to catch them and bring them to the President's annual party honoring Sonic's heroics against Dr. Eggman, and with Sonic's speed and attitude and all that, he and Helen have never had this much fun together in a long time.
  • Wham Line: Season 3 has quite a few, a rather notable example being near the end of Episode 73, when Cosmo turns out to have been an unwilling spy all along:
    Dark Oak: "Good job, White Seed. You accomplished your mission.
  • Wronski Feint: Tails attempts this against Eggman's flying fortress in the Tornado 2 when Eggman launches an extremely accurate missile. It fails.
  • Yank the Dog's Chain: When Amy tries to use a spell to win Sonic over... and it just makes Tails and Cosmo fall in love instead.
  • Year Inside, Hour Outside: When Chris finally manages to get back to Sonic's world via Knuckles' Master Emerald during the Metarex Arc, he is surprised to learn since in their world, its only been a month since Sonic & Co. Went home. In Chris's world, six entire years have passed. There are side effects... This is made even more confusing given the contradictory example in the first season finale, where Sonic finally arrives in his own world, where six months have already passed.
  • You Won't Like How I Taste: Sonic's excuse to prevent a shark from eating him in H2Whoa.


Video Example(s):


Tails and Cosmo (spoilers)

In order to stop Dark Oak, Tails is reluctantly forced to fire on him while he's being suppressed by Cosmo, even though the blast would destroy her as well. Just before pulling the trigger, Tails yells out how he feels about Cosmo, and in her final moments, her spirit reaches out to his as they say farewell and remember everything they'd been through together, with Cosmo's final words to Tails being that she loves him as well.

How well does it match the trope?
