The ''Sonic Rush'' series is a pair of games in Creator/{{Sega}}'s ''Franchise/SonicTheHedgehog'' franchise developed by Sonic Team with Creator/{{Dimps}} and released for the NintendoDS: ''Sonic Rush'' (2005) and ''Sonic Rush Adventure'' (2007). Both games are similar to the ''VideoGame/{{Sonic Advance|Trilogy}}'' trilogy in that they are reminiscent of the classic side-scrollers for the [[SegaGenesis Mega Drive/Genesis]].

The two games have a storyline involving inter-dimensional travel in one way or another, and thus we are introduced to [[TheHero Sonic]] and [[BigBad Dr. Eggman's]] alternate dimension counterparts: Blaze the Cat and Dr. Eggman Nega. The [[MacGuffin Chaos Emeralds]] also have alternate dimension counterparts in the form of the Sol Emeralds, which Blaze must protect at all costs.

A gameplay feature introduced in this pair of games is the Sonic Boost; while holding down the X or Y buttons, your character will gain a boost of speed as long as the tension meter is not empty; the meter can be filled up by destroying enemies and performing tricks. The Boost would later be a major part of gameplay in later 3D Sonic games.

Like the ''Advance'' trilogy, the two games received a solid reception despite the UnpleasableFanbase. Sega have all but admitted that the DS version of ''VideoGame/SonicColors'' (2010) can be considered an unofficial third installment in the series.[[note]]Additionally, the Nintendo3DS version of SonicGenerations can be considered an unofficial fourth installment as well.[[/note]]

'''Playable Characters'''
* '''''Sonic the Hedgehog:''''' Slightly faster and can perform the Homing Attack. Compared to Blaze, his running animation has smaller but faster strides.
* '''''Blaze the Cat:''''' Superior airtime and distance with R-trigger tricks and can slow her descent by shooting flames from her feet. Her running animation is slower than Sonic's but she takes much larger strides.

These would notably the last "original" Sonic games that Dimps made before they switched to making adaptations of Creator/SonicTeam-made console games for handhelds.

----
!!This series provides examples of:
* TwoAndAHalfD / SpritePolygonMix: In an... odd way. Everything except Sonic and Blaze in normal levels is a sprite, but the bosses, their arenas, and special stages use full 3D graphics and somewhat 3D gameplay. And then there's the hang glider in Altitude Limit and the mine cart in Coral Cave, both of which play in 3D, but all the obstacles (save the lava pits in the latter) are sprites.
* AirborneAircraftCarrier[=/=]BubblyClouds: Altitude Limit in the first game.
* AmenBreak: Used in the FinalBoss theme "Bomber Barbara" in ''Rush''.
* AnAesop: [[PowerOfFriendship Friendship is awesome]]! You can't do everything alone.
* AntiGrinding: If you attempt to bounce on the same spring multiple times in order to fill the boost meter, the game will give you less and less energy until you get none at all. ''Rush Adventure'' adds to this by giving you bonus boost stars only after the first bounce off any spring.
* AttackReflector: [[EleventhHourSuperpower Super Sonic's]] boost does this against the TrueFinalBoss of the first game, while it gets split off into its own move in the sequel.
* BadassPrincess: Blaze the Cat
* BigBad: Dr. Eggman and Dr. Eggman Nega in the first game and Captain Whisker in ''Adventure''.
* BiggerBad: [[spoiler:Captain Whisker was actually working for Eggman and Eggman Nega.]]
* BladeLock: [[spoiler:Sonic and Blaze do a variation with their heads by boosting into each other in the Sonic vs. Blaze boss fight.]]
* BodyguardingABadass: You wouldn't think Blaze would need one, but Rush Adventure introduces us to Gardon, a koala who serves as Blaze's personal guard. Possibly lampshaded though, as Gardon doesn't really do anything except inform Blaze of the locations of Sol Emeralds. He even asks Sonic to take good care of the princess.
* BottomlessPits: Loads in ''Rush'', but notably much less frequent until near the end of the game in ''Rush Adventure''.
* CallBack: The cutscene leading to the Last Story in ''Rush'' calls back to the opening cutscene of the Perfect Chaos fight in ''Sonic Adventure'', as the Sol Emeralds are reduced to ordinary stones due to Eggman and Nega draining their power, and Blaze's friendship powers them back up.
* CanonDiscontinuity: The origin of Eggman Nega being from the Sol Dimension has been rendered non-canon by WordOfGod. He's actually Eggman's descendant from 200 years into the future, the same time period that Silver is from as told ''VideoGame/SonicRivals''. However, it's worth nothing that while in ''Rush'', Eggman Nega referred to Blaze's world as "my world" or "our world", in ''Rush Adventure'', which was released after ''Rivals'', he simply refers to it as "this world". Considering the type of person Eggman Nega is, it's not too farfetched that he'd lie about his origins and masquerade as a dimensional counterpart of Eggman to hide his true identity.
* CasinoPark: Night Carnival.
* CatsAreMean: Blaze was a bit of a {{Jerkass}} when she was first introduced. [[DefrostingIceQueen She quickly got better, though.]]
* ClingyJealousGirl: Amy Rose got really pissed when she heard that Sonic was seen with a feline and only calmed down when told it wasn't like that.
* TheComputerIsACheatingBastard: Rush Adventure has Johnny Emerald Races. And the bastards cheats the WHOLE RACE. He cannot be hurt by the player, he can hurt the player, he can drop bombs and fire missiles, has no health bar and a seemingly unlimited boost gauge. On the sixth emerald race, you are going to be so frustrated that your only desire is to break the game card and burn its pieces.
** In Sonic and Blaze's boss fight, they both have [[SecretAIMoves moves you can't normally access]] in the levels! [[JustifiedTrope Obviously justified]] as it ''is'' a boss fight and normally having those moves could make levels easier to finish.
* ContinuityNod:
** Dr. Eggman and Dr. Eggman Nega describe the Chaos and Sol Emeralds as being sort of a north and south pole to each other in the first game. In ''Adventure'', Sonic and Blaze describe it the same way after defeating [[spoiler:the very men who first described it that way]].
** Huge Crisis in ''Rush'' features [[VideoGame/SonicAdventure2 G.U.N. robots]] as enemies.
* ContinuitySnarl: This series says Blaze is from another dimension. ''[[VideoGame/SonicTheHedgehog2006 Sonic the Hedgehog (2006)]]'' says she's from the future. EpilepticTrees tries to rectify this, with one theory stating that Blaze's world is really the future and she only ''thought'' she'd traveled to another dimension. With the release of ''Rush Adventure'', however, this viewpoint holds little ground, as that game goes into further detail about the nature of her world and makes it clear that it is indeed a parallel universe.
** In 2012, it was [[WordOfGod confirmed]] by Takashi Iizuka, the head of Sonic Team, that Blaze is indeed from another dimension, and that Sonic 06 should be ignored.
* CursedWithAwesome: Prior to becoming friends with Sonic, Blaze hated her powers, as they brought her nothing but loneliness and misery.
-->'''Blaze:''' I am the guardian of the Sol Emeralds... It is a fate that forces me to live with my curse, my flames... Because of my powers, I have always been alone... It's also why I must do this alone! It is my responsibility!
* DefrostingIceQueen: Blaze.
* DeusExMachina: [[spoiler:Marine's power came out of nowhere.]]
* [[DistaffCounterpart Distaff Counterparts]]: Blaze and Marine to Sonic and Tails.
* DoesThisRemindYouOfAnything: A non-sexual example, but the FinalBoss track Wrapped In Black, with the constant repetition of "Too black, too strong" had a lot of people making coffee references.
** Actually, Creator/MalcolmX was the first to make a coffee reference. The line comes from "Message to the Grassroots", one of his most famous speeches.
-->'''Malcolm X''': It's just like when you've got some coffee that's '''''too black''''', because it's '''''too strong'''''"...
** [[https://www.youtube.com/watch?v=OzG0GO3U55g Vela-Nova]], the music that plays during the DuelBoss between Sonic and Blaze also counts, especially the soundtrack version. It certainly doesn't like they're fighting.
* DualBoss: Captain Whisker and Johnny in ''Sonic Rush Adventure''.
* DuelBoss: You face off against [[spoiler:the other playable character]] as the boss of the first game's Dead Line.
* ElementalPowers: Sonic ''literally'' [[BlowYouAway becomes the wind]] in the games. As guardian of the Sol Emeralds, Blaze has [[PlayingWithFire flame powers]]. She tried to avoid friendships out of fear of hurting people. And let us not forget [[spoiler:Marine]] who seems to have [[MakingASplash water powers]], despite hiding them until end-game.
* EternalEngine: It wouldn't be a ''Sonic'' game without it.
** Huge Crisis and Dead Line from the first game.
** [[SteamPunk Machine Labyrinth]] from the second.
* EvolvingMusic: In ''Adventure'', the Windmill Village music speeds up and gains instruments every time you craft a new vehicle.
* FateDrivesUsTogether: Blaze seems to suggest this to Sonic at the end of Sonic Rush Adventure.
-->'''Blaze:''' Do you think that maybe you were brought here for a reason?
-->'''Sonic:''' Brought here? By who?
-->'''Blaze:''' (smiling) By the Emeralds.
-->'''Sonic:''' (pauses, looking confused, then smiles) Heh, well, you never know.
* FoeTossingCharge: Other than going faster, this is the boost's primary purpose.
* FourTemperamentEnsemble: Rush Adventure's four-man band.
** '''Sanguine''': Marine.
** '''Choleric''': Sonic.
** '''Melancholic''': Blaze.
** '''Phlegmatic''': Tails.
* GhostShip: The fourth level of ''Adventure''.
* GreenHillZone: In both games, and as the first zone.
* GuideDangIt: ''Sonic Rush'' seems to leave a lot to the player to guess, to the point that the game's own manual doesn't even explain game controls. Some basic moves aren't intuitive, and most interestingly Night Carnival Zone has a point that requires the use of a non-intuitive to move past, creating a trap point much like [[VideoGame/Sonic3AndKnuckles Carnival Night Zone and its infamous barrel.]]
* HeroicLineage: It's stated in Rush Adventure by Eggman Nega that Blaze's royal family has existed and guarded the Jeweled Scepter for generations.
* HijackedByGanon: In ''Adventure'', the BigBad is initially Captain Whisker; however, [[spoiler:the real villains are Eggman and Eggman Nega,]] which is a nice twist because with Eggman, the reverse is usually true. Unfortunately, the plot is spoiled because Whisker looks so much like Eggman, not to mention that Creator/MikePollock is credited as Eggman/Nega in the credits, which you see BEFORE the complete end.
* HotBlooded: Both Sonic and Blaze are this, to varying degrees.
* TheIdiotFromOsaka: The Japanese version of Marine.
* IWorkAlone: Blaze, at first.
* LampshadeHanging: In ''Adventure'', the other three heroes are well aware of how [[TheScrappy annoying]] Marine can be.
* LandDownUnder: The [[AccentAdaptation English-language]] version of Marine. Fitting since Osaka is in the southern area of Japan and Australia is, well, the ''land down under''.
* LeaderWannabe: Marine thinks she's the leader, but only she does.
* LeaveMeAlone: Blaze, at first.
* LetsYouAndHimFight: Played with. Blaze knows Sonic isn't in league with Eggman, but fights Sonic anyway in an attempt to end his involvement in what she considers 'her problem'.
* LoadsAndLoadsOfCharacters: Averted. Sonic and Blaze are the only two characters you can play as in both games, and there are only a handful of supporting characters.
* LonerTurnedFriend: Blaze in the first game, although she's still introverted.
* MirrorBoss: Sonic and Blaze in Dead Line depending on who you're playing as.
* MotorMouth: Marine.
* NeoclassicalPunkZydecoRockabilly: As Hideki Naganuma composed for the first game, it carries his trademark hodgepodge of genres and samples. ''Rush Adventure'' didn't have him as a composer, though its soundtrack mimics his style anyway.
* {{Nerf}}: The RollingAttack's ability to pick up momentum from hills was massively nerfed in order to encourage more use of the new boost.
* NitroBoost: This game marks the first appearance of the Sonic Boost ability. It would later be introduced to the 3D series in ''[[VideoGame/SonicUnleashed Unleashed]]'', ''[[VideoGame/SonicColors Colors]]'', and modern Sonic's ability in ''[[VideoGame/SonicGenerations Generations]]''.
* NostalgiaLevel: The final secret island in ''Adventure'' is a remake of the first zone from its predecessor.
* OppositesAttract: The extroverted Sonic and the introverted Blaze. The AffablyEvil Eggman and the FauxAffablyEvil Eggman Nega.
* PalmtreePanic: The Hidden Island levels in ''Adventure'', the ones that are original levels and not based on Adventure's first 5 stages anyway.
* ParentalAbandonment: In the first game, Blaze tells Sonic that she's always been alone, which would explain her emotional issues and why she's tasked with guarding the Sol Emeralds at the young age of 14. But in ''Rush Adventure'', it's stated that she has a living family, though they are unseen.
* PauseScumming: In the special stages, you control Sonic using the touchscreen. By moving the stylus across the screen, you move Sonic around to the left and right. The thing is, Sonic doesn't actually move towards where you're touching, he just instantly appears at any spot you touch. So if you're having trouble, you can pause the game, touch the area you want Sonic to be at, and unpause to have him appear there much faster than you would normally be able to move your hand.
* ThePowerOfFriendship: The main theme of the series. In fact, like the Chaos Emeralds as discussed in ''VideoGame/SonicAdventure'', this is literally what powers the Sol Emeralds.
* PressXToNotDie: In the zone 7 boss, mashing the B button would [[spoiler:push Blaze (or Sonic) of the edge of the platform, but do nothing or mash too slowly, and they will push you off.]]
* RankInflation: Both games embrace this trope like their 3D brothers, awarding you a lettered rank based on your score in an act/boss fight. The levels are, from best to worst, S, A, B, and C. Furthermore, in the second game, ranks also serve a purpose besides [[BraggingRightsReward bragging rights]]; the better your rank, the more of a mineral you'll get.
* RedOniBlueOni: Dr. Eggman is loud and excitable. Eggman Nega is very [[AddedAlliterativeAppeal calm, cunning and cruel.]]
** At first glance, in contrast to their actual colours, Sonic seems like a good fit for Red Oni (passionate, adventurous) while Blaze seems to be the Blue Oni (stoic, loner). This dynamic, however, is completely shattered during the Dead Line Zone boss fight. [[spoiler:Blaze, with her temper finally at its limit, instigates the battle against Sonic, who originally had no intention of fighting her. Then, during the actual fight, Blaze is the one whose emotions explode while Sonic is the one who tries to calm her down.]]\\
The same occurs at the end of Rush Adventure, where Blaze, in a moment of desperation, nearly blindly runs headfirst into danger, and Sonic has to calm her down and make her see reason. The developers likely did this on purpose, to provide a nice contrast between the two protagonists: Sonic is the free and adventurous, yet level-headed and cool one, and Blaze is the outwardly stoic and blunt, yet inwardly highly emotional one.
* RemilitarizedZone: Huge Crisis in the first game is [[HailfirePeaks also part]] EternalEngine, while Pirates' Island from the second game mixes this with RuinsForRuinsSake.
* RepeatCut: Every time you destroy a boss in the first game.
* RuinsForRuinsSake:
** [[UnderTheSea Water Palace]] and [[ShiftingSandLand Mirage Road]] in the first game.
** [[BubblyClouds Sky Babylon]] and [[RemilitarizedZone Pirates' Island]] in the second game.
* TheRival: Johnny fancies himself to be Sonic's.
** Blaze was also a bit of a rival during the first half of ''Rush''.
* {{Sampling}}: This is probably the first Sonic soundtrack since ''VideoGame/SonicCD'' to have so much of this.
* SarcasticClapping: Eggman Nega likes doing this.
* SchizophrenicDifficulty: In Rush, the last stage is much easier than either of the ones preceding it, and the fourth stage is harder than stage five. For Blaze, the level orders are switched around, meaning one of the most challenging/cheap levels is the first one she plays!
* SensitiveGuyAndManlyMan: Sonic and Tails, sort of.
* SequelDifficultyDrop: ''Adventure'' is easier and has shorter stages than Rush. Most likely due to the ship segments as well and all the missions, but Adventure's levels also have less cheap hits and bottomless pits, so it's easier for more... fair reasons. But 100%ing it is harder due to more challenges, some of which are evil.
* ShiftingSandLand: Mirage Road from the first game.
* ShipTease: There's quite a bit between [[OppositesAttract Sonic and Blaze]]. Especially ''Rush'''s true ending.
* ShoutOut: To ''Sonic Advance 2'': near the normal ending of Blaze's story, [[spoiler:Eggman kidnaps Cream]].
** The music for the true final boss stage in the first ''Rush'' game samples MalcolmX. Yes, ''that'' Malcolm X.[[note]] The sample is Malcolm saying "too black" and "too strong" from his famous "Message to the Grassroots" speech ("It's just like when you've got some coffee that's too black, which means it's too strong"); Public Enemy also used those voice samples as the intro for the original version of "Bring Da Noise".[[/note]]
** Windmill Village's themes seems to be heavily inspired by Sonic 3's File Select theme.
* SlippySlideyIceWorld: Blizzard Peaks in ''Adventure''.
* SpellMyNameWithAnS: Some people still call Marine "Marin", maybe by relation with [[TheLegendOfZeldaLinksAwakening another character who woke up a shipwrecked hero]].
* SpiritualSuccessor: These games are pretty similar to the ''VideoGame/{{Sonic Advance|Trilogy}}'' series. They in turn inspired the handheld versions of ''VideoGame/SonicColors'' and ''[[VideoGame/SonicGenerations Generations]]''.
* SteamPunk: Machine Labyrinth in Adventure.
* TheStoic: Blaze, although [[CharacterDevelopment she does start to]] [[JustForPun warm up]] to Sonic and friends by the end of the first game, and grows an especially powerful bond with Cream the Rabbit.
* TitleScream: In the first game, courtesy of Sonic himself.
* ToCreateAPlaygroundForEvil: Eggman Nega states this as his goal in the second game.
-->''"I shall bring about an age of fear and chaos! And it shall be glorious!"''
* TomboyAndGirlyGirl: Blaze and Cream.
* TrappedInAnotherWorld: ''Adventure''.
* TyrannosaurusRex: The first boss of ''Adventure'' is a [[AnimalMecha mechanized]] one.
* UnderTheSea: Water Palace from ''Rush'', Coral Cave and also Pirates' Island from ''Adventure''. Water Palace and Pirates' Island double as UnderwaterRuins too.
* VariableMix: The final battle theme of ''Adventure'' brings an extra instrument track to the foreground when you're in close proximity to the Ghost Titan.
* WrongGenreSavvy: Marine is convinced ''she's'' the hero and ''Sonic, Tails and Blaze'' are her sidekicks. [[RantInducingSlight Blaze gets fed up with it eventually]].
* YoungerThanTheyLook: Despite her seemingly mature personality, Blaze is actually a year younger than Sonic. To be precise, she's 14 and Sonic is 15.
