-->--'''SonicTheHedgehog''' during his final face-off against [[TheDragon Metal Sonic]].

An hour-long anime {{OVA}} starring [[SonicTheHedgehog everybody's favorite]] [[OverlyNarrowSuperlative blue hedgehog]]. It was originally released in Japan in 1996 (initially as the two half-hour VHS tapes ''Journey to Eggmanland'' and ''Sonic vs. Metal Sonic''); the English dub by ADV was released on September 7, 1999, two days before ''VideoGame/SonicAdventure'' internationally hit the shelves.

Sonic and Tails are chillaxing on the beach when they receive a dispatch from the President of South Island: he and his daughter Sera are being held hostage ([[AffablyEvil for a given value of "hostage"]]) by Dr. Robotnik. Oddly enough, what Robotnik wants is Sonic's help: he's been forced out of his base by the evil(er) Metal Robotnik, who has overloaded the power generator of Robotropolis. In less than a day, the generator will explode and cause [[EarthShatteringKaboom the end of Planet Freedom as we know it]]. Sonic and Tails fly off to the city; along the way, they're joined by the free-roaming treasure-hunter Knuckles (and his hat), who just happens to be in the area.

However, when the trio finally reach the generator, they find that the story was a ruse to extract Sonic's DNA and enable the completion of Hyper Metal Sonic: a robotic dopplegänger who not only has Sonic's speed, but Sonic's personality as well. Also, it turns out that Robotnik [[ILied actually has no compunctions]] about blowing up Planet Freedom, since he'll then rule it by default -- followed by '[[IHaveYouNowMyPretty a life of undisturbed marital bliss with Princess Sara.]]''

''Sonic the Hedgehog'' is widely regarded as that rarest of rarities: [[VideoGameMoviesSuck a video game movie that doesn't suck]]. The voice acting in the English dub is debatable, and it holds only a superficial resemblance to the events of the games, and yet the plot, art, and characterization still do an excellent job of capturing the ''spirit'' of the classic games. In any case, at time of release, the ''Sonic'' series had far less canon to take into account.

Creator/ADVFilms released two different versions of the movie on DVD, although they are both the same dub: the original 1999 version which edited out/censored several bits of the movie, and a 2004 version which is completely uncut.

This film is not to be confused with the anime ''[[Anime/SonicX series]]'', [[WesternAnimation/SonicSatAM four]] [[WesternAnimation/SonicUnderground western]] [[WesternAnimation/AdventuresOfSonicTheHedgehog animation]] [[WesternAnimation/SonicBoom shows]] or the [[Film/SonicTheHedgehog2019 upcoming film adaptation]] also based on the Sonic character.

!!''Sonic the Hedgehog: The Movie'' provides examples of:

* AbnormalAmmo: Metal Robotnik's glue gun, which happens to be located in is... nether regions.
* AccidentalPervert: Sonic can apparently [[PsychicLink see through Metal Sonic's eyes]] due to Metal being a copy of Sonic; this explains why Sonic was blushing when Metal [[PantyShot got a good look up Sera's skirt]]. Tails also grabs hold of Sera after being scared and one of his hands mistakenly [[ThanksForTheMammary grabbing onto one of her breasts]]. Knuckles reads him the riot act.
--> '''Knuckles:''' TAILS! Get off!
--> '''Tails:''' ''[Immediately leaps off her with an embarrassed look]'' I'm so sorry!
--> '''Knuckles:''' I never thought you'd stoop that low!
* AdaptationalJerkass: Sonic is more easily annoyed and angered than his portrayal in the games.
* TruerToTheText: Compared to [[InNameOnly the other animated versions of Sonic in the 90s]], this was the most accurate interpretation of the canon characters at the time.
* AdamAndEvePlot: [[spoiler:The end point of Robotnik's scheme: [[{{Squick}} himself and Sera married]], and the only remaining inhabitants of Planet Freedom.]]
* AffablyEvil: Robotnik. When he isn't acting up the part of hostage-taker for Sonic, he gets along pretty well with Sera and the President. One of his robot minions can be seen cleaning up the President's office.
* AfterTheEnd: It appears this is where Sonic and everyone lives, as seen in the desolate city (among other things) that Sonic and Robotnik fight it and the fact that there's not a lot of other people/creatures/characters aside from the ones we see.
* AlternateContinuity: On this planet, watching this movie, [[WaxingLyrical you'll notice, you'll notice, many things that look alike]]:
** The OVA has its tone, music and art style rooted directly in the original Genesis titles (''[[VideoGame/SonicTheHedgehogCD Sonic CD]]'' in particular), but the explanation for the urban environments found in those games ([[AfterTheEnd post-apocalyptic Earth]] populated with anthropomorphic mutants who live in a sky kingdom ruled by...[[LittleBitBeastly cat people]], we guess) is ''completely'' different from anything else found in the series. Some exclusive characters pop up here and there, and there is no mention of the Chaos Emeralds anywhere. In addition, Knuckles is also depicted as a treasure hunter who lives for the thrill of his job, rather the guardian of the Master Emerald.
** Later games such as ''VideoGame/SonicUnleashed'' did away with all ambiguity by calling it "Earth" and showing Sonic traveling from city to city, [[LightNovel/KinosJourney Kino]]-style, and interacting with humans. Would that the OVA thought up such a mundane solution!
* AlienSky: A planet with Saturn-like rings is visible in the sky.
* AnimationBump: The fight scenes. The rest is [[LimitedAnimation more limited]] despite the designs being (somewhat) similar to those from ''[[VideoGame/SonicTheHedgehogCD Sonic CD]]''
* ApocalypseHow: Robotnik's plans to sunder the link keeping the Land of the Sky attached to the Land of Darkness, which will result in the destruction of all sapient life on the planet bar himself and Sara, is an Invoked case of [[ApocalypseHow/Class4 Class 4]].
* AsYouKnow: Lampshaded; the writers seem to just admit to it - the characters even fall asleep listening to it.
-->'''Robotnik''': As you both well know, Planet Freedom is made up of two separate dimensions. The outer world, the one you live in, is known as the Land of the Sky!\\
'''Sonic''': Tell us something we don't know!\\
'''Robotnik''': SHUT UP! HEED ME!
* BadassAdorable: Tails.
* BadassBookworm: Dr. Robotnik, the creator of Hyper Metal Sonic!
* BabyTalk: Tails sounds like he has this in the dub, despite his ability to create a jet-propelled bodyboard, fly the Tornado, and modify Eggman's navigator into a signal jammer.
* BareYourMidriff: Sera during the first half of the movie shows off her middle, but not so much after she dons her dress later.
* BashBrothers: Taking the characters directly from Sonic 2 and 3 gives us Sonic and Tails, moreso that any other adaptation and even many of the games - a good amount of the movie is huge action scenes where Sonic and Tails engage in coordinated asskicking so effective only the most powerful enemies stand a chance.
* BigDamnHeroes: Knuckles' entrance.
* BigShutUp: '''SHUT UP, TAILS!'''
* BittersweetEnding: [[spoiler:The world is saved, but Metal Sonic (who had then formed a mental bond with Sonic) deliberately allows himself to perish in a glacial volcano. Why? Because "There is only one Sonic."]]
* BlindIdiotTranslation: After crashing their plane upon entering the Land of Darkness, Sonic and Tails crash their plane, the Tornado. Then before departing for Eggmanland, Tails comments that he's "worried about the Tornado". The translators were apparently unaware that this was the name of their plane, as they translated that line as "I'm worried about that tornado".
* BondVillainStupidity: Robotnik is clearly one of those grandiose super villains who doesn't want to simply kill his foe, but first defeat him in something resembling a fair fight. Hence the scene where Robotnik, taking advantage of Sonic's and Tails' distraction, whips out a handgun and shoots Tails' wrist-radar: even though [[BoomHeadshot Tails' head]] must have been an equally clear shot.
* BrickJoke: Eggman launches two bombs at Tails' plane, [[DoesThisRemindYouOfAnything one modeled after a tortoise, the other a hare]]. The hare bomb blows up the plane instantly while the tortoise one crawls away from his hovercraft. Much later, the tortoise bomb crawls towards Eggman and explodes.
* BrilliantButLazy: Sonic, particularly in the opening scene, where he doesn't move a finger to help Old Man Hoot until it becomes clear that Old Man and Tails are in grave danger.
* TheCameo: [[VideoGame/SonicTheHedgehog1 A lone Crabmeat, a swarm of Buzzbombers,]] [[VideoGame/SonicTheHedgehog2 A Caterkiller-colored Crawlton,]] [[VideoGame/Sonic3AndKnuckles and a recolored Snail Blaster]] all make appearances throughout the movie.
* CanonForeigner: Sonic and Tails are enjoying a relaxing day on the beach when they're visited by "Old Man Hoot" ([[{{Pun}} Hoot]] is he?), who's carrying a message so urgent that he doesn't notice his airplane is on fire. The President and his daughter are among the other newbies.
* CatGirl: Sera.
* CatchAFallingStar: Sera falls out of Robotnik's aircraft, and Knuckles catches her in mid-air.
* CatchAndReturn: Sonic [[RidingTheBomb rides]] a missile right back into the robot that shot it.
* CementShoes: Sonic's two weaknesses are combined as he gets glued to the ground in a fissure that is filled by the rain. He's saved by Knuckles and Tails.
* ChairReveal: Sonic and Tails show up for their appointment at the Presidential manor, but are instead greeted by [[SlouchOfVillainy a reclining Robotnik]] and his huge Dr. Claw chair.
* ChasedOffIntoTheSunset: With the day saved, Sonic runs for the horizon. Tails and Knuckles follow, then everyone else piles into Robotnik's Eggmobile and flies after. Sonic realizes that everyone is following him, and he puts on a burst of speed before the credits roll.
* ChekhovsGag: Robotnik's extremely-slow-moving turtle missile. [[spoiler:It pops up later just in time [[HoistByHisOwnPetard to destroy the CD Robotnik has with Sonic's DNA data that he could use to make another Metal Sonic]].]]
* CompilationMovie: The western release of the OVA consists of both episodes of the OVA played as an hour-long movie.
* CompositeCharacter: The OVA made Knuckles a treasure hunter just like [[VideoGame/SonicTheHedgehogTripleTrouble Fang the Sniper]], and gave him [[NiceHat a hat]] similar to his.
* CoolOldGuy: Old Man Owl.
* CurbStompBattle: Sonic is almost effortlessly beaten by Metal Sonic in their first fight, and only survives because Metal Sonic loses track of him. Interstingly, their final fight was ''also'' turning into a curb stomp battle before Tails interferred, as Sonic didn't have the stamina to keep up with Metal Sonic for more than a couple of minutes. If Tails hadn't stepped in and corrupted Metal Sonic's programming, Sonic would have been killed.
* CuteButCacophonic: Sera.
* DarkerAndEdgier: Well, compared to the older games, it could be.
* DeathCourse: The path to Robotropolis, though Sonic and Tails make short work of it.
-->'''Sonic''': I bet Robotnik purposefully picked the route with the most traps for us!
* DiabolusExNihilo: Quite literally, as Metal Robotnik "appeared out of nowhere!" before kicking Robotnik out of his home. It's signposted very early on that Metal Robotnik is under the Doc's power, but it's remarkable that he couldn't think up a more plausible threat.
* DistressedDamsel: Sera... sort of. She plays the role of hostage when Sonic's around, but she treats Robotnik like a friend the rest of the time.
-->(''Sera and Robotnik are playing a fighting videogame. Sera loses.'')\\
'''Sera''' (''hysterical''): No no no no no it's not fair you always beat me every time! (''abruptly regains her composure'') Alright, one more!\\
'''Robotnik''': Just give up! We've played a hundred times!\\
'''Sera''' (''devious''): I'll stop being your hostage...\\
'''Robotnik''': Alright, start it again.
* TheDitz: Old Man Hoot didn't even realize his ''rocket was on fire''!
* TheDragon: Metal Sonic.
* DubNameChange: The official English dub renames Dr. Eggman to Dr. Robotnik for one of the last few times (as it was released in 1999). To go along with it, Eggmanland was renamed Robotropolis (as a ShoutOut to the [[WesternAnimation/SonicSatAM Saturday morning cartoon]]) and Black Eggman was renamed Metal Robotnik. In addition, Sera was renamed Sara; her and Eggman's names are still displayed clearly in the fighting game gag, however. The official subtitles included in the DVD release go with the Japanese terminology and retranslate the script more accurately to boot. Cue SubbingVersusDubbing.
* EarlyInstallmentWeirdness: Since the movie was released only five years into the franchise's life, there are some moments that would nowadays be considered majorly [[OutOfCharacterMoment out of character]], such as Sonic telling Tails to shut up, and Knuckles describing himself as "Sonic's best friend". While Knuckles clearly respects Sonic, and they get along (most of the time), he's much too gruff to say something like that. Sonic is also depicted as somewhat quick-tempered, contrasting his cool and laidback portrayal from later games, who is described as being "always cool under pressure" by official bios.
* {{Egopolis}}: Robotropolis, aka Eggmanland. At night, the city's lights form a picture of Robotnik's face.
* TheEndOfTheWorldAsWeKnowIt: Two different schemes are mentioned. [[spoiler:Metal Robotnik's exploding generator turns out to be fake]], but [[spoiler:Hyper Metal Sonic's attempt to shatter the continents is very real]].
* EverybodyLaughsEnding
* EveryoneCallsHimBarkeep: The President.
* EvilKnockoff: Metal Sonic, natch.
* {{Expy}}: Sera is pretty much a humanoid Amy Rose. The presumed reason for Amy's absence is that her being the president's daughter as well as Eggman's 'interest' would not have worked well for ''several'' reasons.
* FaceFault: Sonic and Tails do this simultaneously when Old Man Owl starts to convey his message before stopping abruptly, having a minor fit... and starting all over again.
* FamilyUnfriendlyDeath: [[spoiler: After being dismembered over the course of his fight with Sonic and even moreso after the President's rocket explodes, Metal Sonic basically commits suicide by letting himself sink into lava.]]
* FastballSpecial: Used twice in a row to defeat Metal Robotnik.
* FingerWag: Sonic to Metal Robotnik. Often mistaken by fans for [[FlippingTheBird another gesture entirely]]. To be fair, it ''is'' the case in some edits of the film.
* FearOfThunder: Tails. ''"I'm afraid of lightning!"''
* FearfulSymmetry: Portions of Sonic's fight with Metal Sonic.
* FlashStep: Sonic, Tails, and Metal.
* FloatingContinent: Between the plethora of floating landmasses and the cloud cover, the surface of Planet Freedom is largely shrouded in darkness; hence why it's called "the Land of Darkness". This is probably also the reason that the entire population lives on the outer layer, "the Land of the Sky".
* TheFool: Old Man Hoot.
* GadgeteerGenius: Tails. He builds a hover-surfboard in his spare time, disassembles one of Robotnik's radars, and later reassembles it as a device that can track Metal Sonic: [[spoiler:and wirelessly interfere with Metal's programming]]. This movie appears to be where Tails' mechanical tendencies come from, in fact.
* GagDub:
** Reputable Dubbing's ''WebVideo/SonicTheOtherMovie'' is a comedic rewrite of the movie, made by Sonic Paradox's Smegerama. Though most of it is the same story, the dialogue and various visual gags change it into a mostly comedic experience.
** Website/Fireball20XL's ''[[https://www.youtube.com/watch?v=-HgYA-32v9Q Sonic Bastardized]]'' is a redubbed adaptation in which [[strike:Robotnik]] Eggman wants Sonic to go shut off a bomb he planted in Creator/BlizzardEntertainment's mainframe (in retribution for his ''VideoGame/WorldOfWarcraft'' losses), and Metal Sonic is a robot named Hyper Metal Jason (after Creator/JasonGriffith) that Eggman intends to use to replace Sonic's voice.
--->'''Sonic:''' Pansy-ass [[ScrappyMechanic blood elf!]]
--->'''Robotnik:''' SHADDAP! Blood elves are cool!
** Then comes The Rollan Nolan's ''[[https://www.youtube.com/watch?v=Zja-kAZUbY0 Sonic the Abridgehog]]''.
* GetAholdOfYourselfMan: Sonic attempts to knock some sense into Old Man Hoot [[JerkWithAHeartOfGold by making a]] [[VideoGame/SonicTheHedgehog1 Crabmeat]] [[JerkWithAHeartOfGold pinch him]], [[TheDitz with limited success]].
* GoKartingWithBowser: Dr. Eggman is seen playing around with the president and his daughter in several scenes.
* HeelFaceRevolvingDoor: Sera can't seem to decide whose side she's on.
* HereWeGoAgain: Averted. [[spoiler:Eggman reveals after the final battle that he still has the data of Sonic's DNA via a CD, which he'll use to make another Metal Sonic to combat Sonic again...[[ChekhovsGag only for the missile turtle Robotnik fired away earlier to arrive on time and destroy the CD by accident]].]]
* HumongousMecha: Metal Robotnik is actually a giant robot piloted by Robotnik.
* HumanSnowball: Happens to Tails after Eggman blows up his plane in the mountains.
* InASingleBound: Sonic and Metal Sonic in particular are seen pulling off several ''massive'' jumps over the course of the film, often when traveling at speed or fighting. It's most notably seen in their second fight scene, where the two are moving so quickly that they're only visible as streaks of coloured light.
* {{Infodump}}: Eggman's speech to Sonic at the White House.
* JerkWithAHeartOfGold: Sonic.
* KnightOfCerebus: Metal Sonic. Before him most of the film played most everything humorously, Eggman barely even qualify for much a threat due to the GoKartingWithBowser above. Then Metal Sonic shows up and BOOM, we have a villain that's actually dangerous and for the most part, nothing about him is played humorously.
* LeftForDead: Subverted! [[spoiler:Metal Robotnik shoots the bridge from underneath Sonic and Tails; they grab bridge girders just out of sight and make gurgling sounds to convince Metal Robotnik that they're drowning. Just when they think he's left..."I see you! You didn't think I'd fall for a stupid trick like that, did you?"]]
* LastSecondChance: [[spoiler:Hyper Metal Sonic rescues the President and Old Man Owl from an exploding rocket towards the end of the film, but having been dismembered in his fight with Sonic and then by the resulting explosion, he falls into the magma pit below and is melted on-screen, refusing to be rescued by Sonic on the grounds that ''"there is only one Sonic"''.]]
%% * LavaPit
* KilledOffForReal: [[spoiler: Hyper Metal Sonic.]]
* MakesUsEven:
-->'''Sonic''': Thanks a lot, pal! I owe you one!\\
'''Knuckles''': I think we're even.
%% Memetic Mutation belongs in the YMMV page. Do not post it here.
* MoodWhiplash: The scene where [[spoiler:Metal Sonic dies is really stuck in utter contrast to the previous scene, which was a comedic albeit intense action-packed battle. Heck, it sticks out in utter contrast with the rest of the film's tone and mood in general.]]
* MotivationalKiss: Sera gives one to Knuckles.
* MythologyGag: Throughout the Land of Darkness, Sonic and Tails are shown avoiding various spikes on the ground, followed by Sonic jumping onto a spring.
* NeckLift: Metal Sonic does this to Sonic whilst simultaneously throttling him.
* NeverSayDie:
** Averted. "When you awaken... KILL him!" (cue EvilLaugh)
** Also averted when Robotnik meets Sonic at the Generator.
-->'''Robotnik''': You fell for my trap! You came all the way here and now you'll die here. [[NiceJobBreakingItHero Good job, Sonic]]!
* NiceHat: Knuckles has one. If just for the RuleOfCool. Used for a CrowningMomentOfFunny later when it gets set on fire in the climax of the film.
-->'''Knuckles''': '''MY HAT'S ON FIRE, HELP!'''
* NobleDemon: Hyper Metal Sonic.
* NotSoHarmlessVillain: Robotnik is set up as a bumbling, buffoonish idiot who is actually being bullied by his supposed "hostage" in several scenes. Then comes the last third of the film, where it reveals Metal Sonic is the key to his latest plan, which itself consists of ''the complete genocide of all sapient life on the planet''.
* OcularGushers
* OnlyOneName: Sera.
* OohMeAccentsSlipping:
** Dub Sonic will sometimes switch back and forth from sounding like a southern teenager to a British {{Bifauxnen}} when the voice acting gets particularly energetic.
** Robotnik will also occasionally slip into an indeterminate European accent, noticeably when he shouts "FINE! DON'T BLAME ME WHEN THIS HAPPENS!"
* OurPresidentsAreDifferent: He's both President Target and President Buffoon.
* PantyShot: [[spoiler:During the climactic battle, Metal Sonic's head gets knocked through the bottom of Robotnik's hovercraft, right under Sera's dress. While we don't actually see anything, Sera is unsurprisingly pissed and starts kicking him in the face.]]
-->[[spoiler:'''Sera''': Back, no no no! Don't look there, you pervert!]]
* PersonalityChip: Thanks to the wristwatch Tails received from Eggman that he managed to dismantle, he is able to [[spoiler:wirelessly mess with Metal's personality programming,]] and this gives Sonic a crucial advantage in the fight.
* PetTheDog: After winning his first fight against Sonic, Metal Sonic tracks down Old Man Hoot and...[[spoiler:gives him Sonic's favorite clothes]].
* {{Pilot}}: The film was originally released as two separate half-hour pilots in Japan, [[GermansLoveDavidHasselhoff but due to Sonic's lack of popularity there]] the potential anime series never got off the ground. When it was dubbed, the two specials were merged together and released in the US as what we call ''Sonic the Hedgehog: The Movie''.
* PimpedOutDress: In the climax, Sera wears a white dress [[FluffyFashionFeathers trimmed with feathers]].
* PokeThePoodle: Among Metal Sonic's acts of evil he randomly decides to steal Sonic's favorite clothes and give them to Old Man Hoot.
* PowerCreepPowerSeep: In ''[[VideoGame/Sonic3AndKnuckles S3&K]]'', Knuckles could glide through the air. Here, it gets upgraded to the ability to jump ridiculously high, hover in midair, and possibly fly outright. Like Tails' propensity for mechanical shenanigans, this movie seems to be the start of a trend of non-game media to upgrade Knuckles' gliding to full-fledged flight.
* PunctuatedForEmphasis: [[spoiler:As Metal Sonic dies, he says, "THERE. IS. ONLY. ONE. SONIC-NIC-NIC-NIC-NIC."]]
* PsychicLink: Between Sonic and Metal Sonic.
--> '''Sonic''': You might know everything I'm going to do. But that's not going to help you, since I know everything ''you're'' going to do! [[MemeticMutation STRANGE, ISN'T IT?!]]
* RealMenWearPink: Sonic's aforementioned "favorite clothes" include a pink shirt.
* RedOniBlueOni: Sonic is the RedOni to Tails and Knuckles' BlueOni's.
* RedemptionEqualsDeath: [[spoiler:Metal Sonic]]
* RetCanon: A few elements from this incarnation were carried over into the games:
** The terms "Eggmanland" and "God of Destruction"
** The idea of Knuckles being a treasure hunter
** The depiction of Station Square as a flooded city in ruins at the end was likely inspired by the ancient ruins in the OVA, even using much of the same imagery
** Several of Tails' game bios mention that he's afraid of lighting. The earliest known mention of this trait in the context of the games was ''VideoGame/SonicJam'', which came out a year after this OVA, so it's likely another example of the trope.
* RidingTheBomb: Sonic, on one of Metal Robotnik's missiles.
* RoboCam
* RuinsOfTheModernAge: The "ancient relics" on the outskirts of Robotropolis/Eggmanland resembles an abandoned New York City.
* SceneryPorn: Damn, Planet Freedom looks pretty cool.
* ShatteredWorld: Planet Freedom.
* ShoutOut:
** One of the derelict aircraft on Sonic's island looks suspiciously like [[Franchise/StarTrek the USS Enterprise]].
** Sera's wedding dress is reminiscent of [[Franchise/SailorMoon Neo-Queen Serenity]]'s outfit.
** During the view of the city of the Land of the Sky, there's a building with a design that looks suspiciously similar to the classic [[Creator/{{Rare}} Rareware]] logo.
* ShutUpHannibal: Robotnik gets a whack from an annoyed Sara when he gloats about how Sonic will face an even greater threat than his just-defeated Metal Robotnik.
* SilentAntagonist: Metal never talks [[spoiler:until the end, when he sinks into lava]].
* SlidingScaleOfAdaptationModification: The OVA is a Type 2 (Recognizable Adaptation).
* SpellMyNameWithAnS: Her name is Sera in the original Japanese, and Sara in the English dub. "Sarah" is right out.
* SpoilerOpening: The very first scene is Dr. Robotnik talking about acquiring Sonic's life data for Metal.
* StoryboardingTheApocalypse: Knuckles' explanation of how exactly [[spoiler:Metal Sonic is capable of destroying the planet]].
* StupidStatementDanceMix: [[http://www.youtube.com/watch?v=n9fHGdR1IyM Planet Freedom, Planet Freedom, they conquered Planet Freedom.]] [[http://www.youtube.com/watch?v=giCpc4XGiKw We're going to the North Pole, North Pole, North Pole. That means Tails finally found the point of Planet Freedom, yes!]]
* SurprisinglyGoodEnglish: The ending song, "Look Alike", is sung (and spoken for a bit) in, for the most part, [[note]][-The singer pronounces memory as "memorai" in one verse, which itself isn't entirely grammatically sound.-][[/note]] well-pronounced and grammatically correct English.
* TakeMyHand: [[spoiler:Sonic to Metal when the latter is about to sink into lava. Metal declines, saying "There is only one Sonic..." and then dissolves.]]
* ThereCanBeOnlyOne: This, rather than Robotnik's order, is Metal Sonic's real motivation for trying to kill Sonic. [[spoiler:And ultimately, his reason for declining his LastSecondChance after losing to Sonic.]]
* ThisIsSomethingHesGotToDoHimself: Sonic insists that he has to defeat Metal alone. Initially.
* TheUglyGuysHotDaughter: Sera.
* TranslationTrainWreck: One DVD version of the movie has subtitles that, for example, call Knuckles "Knucklus," Eggman "Machine King," and Tails "Dillus". The character section of the DVD also misidentifies Knuckles as a mole.
* UnusualEuphemism: "Sonic will never again be a pain in my egg!"
* WallJump: Sonic, of course.
* WhatMeasureIsANonUnique: The reason [[spoiler: Metal Sonic allows himself to fall into the lava]] near the end.
* WhatTheHellIsThatAccent: Sonic's voice in the English dub has a very bizzare, indeterminate accent.
* WordSaladLyrics: The lyrics to "Look Alike," the ending tune of the film. While look-alikes are a theme in this movie, the rest of the lyrics are a bit... stream of consciousness.
