[[caption-width-right:225:An adventure that's truly out of this world!]]

->''"Welcome to the Galaxy!"''

[[Franchise/SuperMarioBros Mario]]... '''[[RecycledInSpace IN SPAAAACE!!!]]'''

Mario is on his way to visit Princess Peach so that they can observe a comet streaking past the Mushroom Kingdom together, but suddenly, [[BigBad Bowser]] returns once again to kidnap Princess Peach. The attack launches Mario into space and he awakens on a strange small planet, where he meets Rosalina, a person that protects the cosmos and living star-shaped creatures called the [[RidiculouslyCuteCritter Lumas]]. After taking Mario to her Comet Observatory, she explains that Bowser has stolen all power from the Comet Observatory to fuel his army and create a new kingdom for himself. Mario must [[GottaCatchThemAll retrieve all the stars]] for Rosalina so the Comet Observatory can venture to the center of the universe where Bowser awaits...

Released in 2007, ''Super Mario Galaxy'' is a {{Platformer}} for Creator/{{Nintendo}}'s {{Wii}} with gameplay similar to ''VideoGame/SuperMario64''. Though unlike ''VideoGame/SuperMario64'' as well as ''[[VideoGame/SuperMarioSunshine Sunshine]]'', the gameplay is noticeably more linear with less focus on exploration. In this game, Mario flies around from planet to planet with the help of Rosalina and The Lumas to retrieve Power Stars. There are additional gameplay elements with the Wii Remote such as spinning to attack enemies and jump higher. Power-ups return to this series, two of which are from the original game that started it all.

The game is also notable for being the first Mario game to feature music played by a live orchestra. Though Mario series veteran Creator/KojiKondo was in charge of the soundtrack, the orchestrated bits were done by MahitoYokota, who was previously the composer for ''DonkeyKongJungleBeat''. As a result of working on this game, Yokota has become the go-to guy for orchestral arrangements for games that Kondo has composed for.

A direct sequel, ''VideoGame/SuperMarioGalaxy2'', was released on May 23, 2010.

----
!!This video game provides examples of:
%% ZeroContextExample entries are not allowed on wiki pages. All such entries have been commented out. Add context to the entries before uncommenting them.
* {{Two-D Space}}: Notably {{averted|Trope}}, as all three axes of movement are used.
* AddedAlliterativeAppeal: The names of many galaxies. The Kitchen observatory alone gives us the Beach Bowl, Bubble Breeze, and Buoy Base galaxies.
* AlreadyDoneForYou: After you rescue him from the haunted mansion, Luigi will go out looking for Stars on his own. However, he invariably gets stuck in whatever galaxy he's in, forcing you to go rescue him to obtain the star. There are also several galaxies in which Toads have already retrieved the Star, you just have to go get it from them.
* AlwaysAccurateAttack: Doing a GroundPound just after spinning in midair allows it to home in on enemies.
* AndThatLittleGirlWasMe: [[spoiler:The girl in Rosalina's story happens to be her in the end of the story.]]
* {{Antepiece}}: Nearly every boss level uses a game mechanic or enemies with unique defeat strategies (if the boss is a KingMook) that will be used to defeat the boss. 3 examples:
** The Kamella's Airship Attack level revolves around throwing Koopa shells to break chests and progress through the level. Kamella is defeated by ''throwing the shells she summons at her''.
** Major Burrows's minions are the Undergrunts, enemies you have to ground-pound to get them out of the ground, and then jump on them/spin them to kill them. Major Burrows is a [[KingMook very large Undergrunt]], so naturally, the same strategy is required, though you have to chase him once he's out of the ground.
** Baron Brrr is an enlarged Li'l Brrr. The Li'l Brrrs are defeated by spinning them (they float) to extinguish their ice cloud and bring them to the ground. They will turn darker and bounce around the ground, trying to fall into ice water to revive themselves. If you kick them by walking into them in this state, they will be defeated, and drop a coin. Their Baron is very much the same, but with added attacks.
* ApocalypseHow: [[spoiler:After the implosion of the sun Bowser created at the universe's center implodes, it's heavily implied that, aside from Mario and Rosalina, nothing was actually ''saved'', per se--rather, the Lumas ''recreated'' everything.]]
* ArtisticLicenseAstronomy: Obviously.
* AttackOfTheTownFestival: The story of the game begins when Bowser attacks the Mushroom Kingdom during the Star Festival.
* AttentionDeficitOohShiny: The penguins in Beach Bowl Galaxy can't concentrate on their swimming lessons because they're distracted by the "[[BuffySpeak sparklies]]" (star shards) in the ocean.
* BabyPlanet: Practically all of them. Heck, some planets aren't much bigger than Mario himself, yet still have enough gravity to hold him down. The most extreme example is in Deep Dark Galaxy, where Mario will encounter a bonus planet that, once he undoes a screw to reveal a circle of coins, is constantly shrinking, and no matter how small said planet gets, Mario won't escape from its gravitational pull until the planet vanishes completely. Also quite literal as some Lumas (which are literally babies) will ''explode into planets when you feed them enough Star Bits.'' Some will explode into ''galaxies'' later on in the game.
* BackStory: The Library allows the player to read [[spoiler:Rosalina's backstory, which explains how she got into outer space and became the "mother" of Lumas. It also describes her longing for the home and family she left behind]].
* BaitAndSwitchBoss: Bowser Jr.'s final appearance in the game. He kidnaps Peach and fires canonballs to destroy Mario's steps... only to watch the final battle between Mario and Bowser.
* BatmanCanBreatheInSpace: Actually justified for Mario early in the game (his Luma presumably gives him this ability). As for everyone else, though, the trope applies (likely via ToonPhysics).
* BattleTops: One of the bosses, Topmaniac, is a top. He is the leader of the Topmen, smaller sentient tops.
* BigBoosHaunt: Several galaxies. Ghostly Galaxy is the classic haunted mansion iteration, while Deep Dark Galaxy is an ''underwater'' variation.
* BigEater: A lot of the Lumas will ask for large amounts of star bits - so large, in fact, that they explode and somehow create planets.
* BrickJoke: Halfway through the game, the napping yellow Toad will mention the word rotisserie. [[spoiler: In the Grand Finale Galaxy, you can find the Toad Brigade roasting a rotisserie meat.]]
* BonusStage: Some of the pipes lead to underground areas where you can collect more star bits, coins, or 1-ups.
* BookEnds:
** The first boss in the game is Dino Piranha, and the last boss (not counting Bowser) is [[IncendiaryExponent Fiery Dino Piranha]]. In fact, Dino Piranha is the first Star in the first galaxy (not counting the Gateway Galaxy), and Fiery Dino Piranha is the last Star in the last galaxy (not counting Prankster Comets or bonus galaxies.
** [[spoiler: In the opening of the game, you're in the Mushroom Kingdom, celebrating the Star Festival. Guess when and where the Grand Finale Galaxy is situated?]]
** The first challenge you do in the game is play hide-and-seek with bunnies on a small planet. The last Hungry Luma level involves you finding bunnies in a smaller, snowy planet.
* BootstrappedTheme: The [[http://www.youtube.com/watch?v=VEIWhy-urqM Gusty Garden Galaxy theme]], particularly at around 1:24, is pretty much the main theme of the Galaxy series now, and was featured prominently in the SuperMarioGalaxy2 soundtrack.
* BossArenaIdiocy: Topmaniac would be invincible if he would just get rid of that electric fence around his arena.
* BossArenaRecovery: Many of the boss arenas have little lights or plants on the ground that you can shoot star bits at to produce coins to restore your health. Some of the fights even have coins and star bits in the arena itself. And as if you weren't constantly picking up Star Bits during both the preceding level and boss fight, hitting a boss enough times to start their next phase usually causes dozens of Star Bits to pop out of them.
* BossOnlyLevel: Bonefin Galaxy. The only mission in it begins on the Starshroom, and when Mario uses the Launch Star, he's launched to the only actual planet in the galaxy. The battle against Kingfin begins immediately, and the mission ends when Kingfin is defeated and Mario can collect his Power Star.
* BottomlessPitRescueService: Rosalina will pull Mario up if he falls in the HubLevel.
* BubblyClouds: Gusty Garden, while not having any clouds to walk on, definitely has the same feel with multiple platforms being suspended in the sky.
* ButterflyOfDeathAndRebirth: [[spoiler:When Mario wakes up in the new galaxy in the ending, there is a butterfly sitting on his cap.]]
* ButtMonkey: Luigi always gets captured or trapped while he is looking for a Star. At one point, he gets trapped on the top of a ''small house'' that Mario can easily triple jump on top of.
* TheCameo:
** Yoshi actually makes a brief appearance in this game as two different planets: one in the save file screen, and the other in Space Junk Galaxy.
** During the prologue, when Bowser captures Peach and carries both her and her castle high up into space, when Mario starts to go after Bowser as he is about to fly away with his airship brigade to save the princess, a Magikoopa immediately swoops down and attacks him, sending Mario toward a small planetoid nearby and knocking him unconscious. According to [[AllThereInTheManual the tie-in trading card game,]] that Magikoopa is actually [[YoshisIsland Kamek]].
%%* CameraCentering
* CameraScrew: Most of the time, you can't control the camera's position; several challenges in this game would be a lot easier if you could actually ''see what you're doing'' (though the game is a ''lot'' better than ''VideoGame/SuperMario64'' in this regard).
* CerebusSyndrome: For all its cheerful charm, the game includes some melancholy elements. This includes Rosalina's TearJerker storybook, as well as the ending, where [[spoiler:the entire universe is destroyed due to a ''massive'' black hole and all of the Lumas throw themselves into the black hole to neutralize it and recreate the universe.]]
* ChainsawGood: Topmaniac has a ''red-hot'' one, with ten yellow spikes on its side.
* ChasingYourTail:
** Dino Piranha is defeated by spinning on his tail.
** To damage Bowser, Mario must spin on Bowser after getting a platform to explode under him. Because Bowser is smart enough to run away, Mario usually has to chase him by going the other way.
* ColossusClimb: Megaleg and Heavy Metal Mecha-Bowser. Also present in the first level of Honeyhive Galaxy, where Bee Mario has crawl all over the Queen Bee's massive body in order to collect the five star chips embedded in her hair.
* ConvectionSchmonvection:
** So [[ToonPhysics off the wall]] here, it had to be mentioned ''twice''. The final fight between Bowser and Mario have them fighting on an exposed battleground inside ''an artificial star''. Not to mention Melty Molten Galaxy, which takes place on a ''planet'' '''''made of lava!''''' Justified since you're in space, where there is no air or other fluid to convey the heat.
** Ice Mario can freeze ''lava.'' As said below, RuleOfCool.
** In the Freezeflame Galaxy's third mission not only can you skate on a ring of ice with several ''stars'' embedded in it, but you can stand as close as physically possible to lava before you actually go in it and not get hurt.
* CoOpMultiplayer: The Co-Star Mode in both games. The sequel expands on it by including an orange Luma.
* CosmeticAward: Get 9999 star bits? The coconuts turn into watermelons.
%%* CoupDeGraceCutscene
* CriticalAnnoyance: The "low battery" sound and icon implemented in the game for the Wiimote. Really just there to annoy you since they game will helpfully pause the game when the battery finally bites it. Similarly, an alert sound will play when you're down to one wedge of health...and won't stop until you replenish it.
* CyclicalTime/ParallelUniverse: [spoiler: Rosalina speaks about the cycle of the galaxy at the end of the game and that it repeats itself, but never in the same way. Almost like a parallel universe (or rather, galaxy), but with each one following one after the other, hence "cyclical time".]
* DarkerAndEdgier: This time, Bowser goes beyond kidnapping the Princess, and actually trying to taking control of the whole Galaxy/universe. [[spoiler:And said Galaxy gets destroyed and recreated.]] Add in the aforementioned CerebusSyndrome too and the result is a Mario game with more than just the usual Princess that needs saving. Downplayed in that it is still quite cheery, though.
* DeadlyDodging: Many levels require you to lure Bullet Bills into crashing into things you need blown up.
* DeliberateInjuryGambit: Sometimes it pays to let an enemy hit you in order to lose an inconvenient power-up. (I'm looking at you, Spring Suit.)
* DemBones: Kingfin and Dry Bones. The former is a skeleton shark and the latter are Koopa skeletons.
* DiabolusExMachina: Meta-example: it'd be impossible to fall off of most planets if it weren't for the {{Unrealistic Black Hole}}s.
* DivergentCharacterEvolution: The five different-colored Toads from ''VideoGame/SuperMarioSunshine'' are back, and this time, each one has his own distinct personality.
* DivineAssistance: Rosalina, for the one or two parts she actually decides to aid you.
* DoWellButNotPerfect: In the levels where you have to swim behind Guppy and go through the rings that he puts out, if you're such a fast swimmer that you actually catch up to Guppy, the knockback from when he hits you can easily cause you to miss a ring.
* DramaticWind: Bowser's flapping hair is rather hypnotic, isn't it?
* DubNameChange: The galaxies all had English names even in the original Japanese version. A few of them stayed the same, but most were changed despite the fact none of them really sounded very Engrish-y (for instance, Melty Molten Galaxy was called Hell Prominence Galaxy in the Japanese version). This is averted in other language versions of the game, such as Spanish and French.
* DummiedOut:
** The sheer amount of unused stuff found upon cracking the game open is enough to make one's head spin. Everything from unused boss designs to unfinished planets can be found in there.
** An almost-finished planet, the Starman Fort, resembling an excavation site, still has its files inside the game, albeit with messed-up gravity, but nevertheless is much more complete than some of the planets that made it to the final version. It was even supposed to house a bunch of missions, and even the first boss battle according to a concept art!
** There is also the alternative hub planet shown at the E3 2005, and an urn-shaped planet with a question mark on it. Another planet has a dozen of climbable poles with some spiked urchins down.
** Mario himself has some unused moves, such as punching and tennis moves. An unused 3D model for a kart exist also, along with Donkey Kong Jungle Beat models.
* DynamicLoading: The Launch Star animations were used to hide the game loading the next planet.
* EasterEgg: If you look very closely while on the third planet in Toy Time Galaxy, you can actually see a tiny model train inside one of the cracks in its walls.
* ElectricJellyfish: There's a huge one guarding the entrance to the underground lake in Deep Dark Galaxy.
* EternalEngine: Several, most notably Battlerock and Dreadnought.
* EverythingsBetterWithBunnies: There's three of 'em at the start of the game.
* EverythingsBetterWithPenguins: By now, it's a Mario series tradition to include [=NPC=]s who are penguins. They show up in Loopdeeloop Galaxy, Sea Slide Galaxy, Drip Drop Galaxy, Buoy Base Galaxy, Loopdeeswoop Galaxy and Beach Bowl Galaxy.
* EverythingsBetterWithSpinning: Mario's main attack after jumping. In fact, it even makes enemies drop Star Bits instead of coins!
* ExcusePlot: The main plot is as simple as most ''Mario'' stories, but the semi-extensive backstory to Rosalina given in the storybook isn't.
* FamilyUnfriendlyDeath: Some of the death animations involve Mario getting disintegrated, suffocating in quicksand, and electrocution, ''leaving behind a skeleton!''
* FixedCamera: [[FreeRotatingCamera Except for some areas]], the game generally doesn't allow you to change camera angles.
* FlightOfRomance: Mario and Peach have such a moment after he delivers an epic beatdown to Bowser at the end. He catches her as she falls from Bowser Jr.'s airship and whisks her away with the final Grand Star.
* FloatingInABubble: The Bubble Breeze and Bubble Blast Galaxies. You can also use a bubble to obtain a secret Star in the Gold Leaf Galaxy.
* FloatingWater: Loopdeeloop and Loopdeeswoop Galaxies both feature a long flow of floating water where Mario plays Manta Ray Surfing.
* FlunkyBoss:
** Topmaniac's battles begin with two Topminis or two Spiky Topmen on the arena, and he can summon more at certain points.
** Kamella summons Magikoopas during the last phase of her boss fights in Deep Dark Galaxy.
** Kingfin summons Fishbones (that attack in the same way as Torpedo Teds) during his battle.
* FlyingSaucer: Bowser's Flying Saucer cuts out Princess Peach's castle and lifts it up in a beginning cutscene.
* FollowTheLeader: Since ''Galaxy'' first came out, there has been a large influx of gravity-based flash games across the Internet.
* {{Foreshadowing}}: [[spoiler: Rosalina states at the end a bunch of stuff about the galaxy never repeating itself the same way and that "you'll see", obviously implying that the differences will be important later on.]]
* FourLeggedInsect: The [[http://www.mariowiki.com/File:SMG_Honeyhive_Bee.png bees]] that appear in galaxies like Honeyhive Galaxy have four legs. This also applies to the Queen Bee.
* FreeRotatingCamera: Only in a few areas. The others [[FixedCamera doesn't allow you to rotate the camera]].
* FreeSamplePlotCoupon: Mario's goal is to retrieve the Grand Stars that fuel the Comet Observatory built by Rosalina. Luckily for him, the first of these Stars is the only one that isn't guarded by any of the bosses. Also a case of BackFromTheBrink.
* GainaxEnding: Mario watches as [[spoiler:a huge black hole forms in the center of the universe as the Lumas fly into it and cause the hole to implode at first, sucking Mario, Bowser, Peach, and ''everything in the universe into it'', then explode violently]]. After that, Mario [[spoiler: faces a huge Rosalina that says new baby stars are being born as a result (complete with baby crying)]]. After that, Mario and the gang [[spoiler: wake up in the Mushroom Kingdom, only it's now a fusion of all the worlds that he visited.]]
* GameBreakingBug: Although this game has received top-notch QA, some glitches exist, making Mario die if he spend too much time orbiting around a planet without actually landing on it (especially frequent with Luigi, by abusing the long jump/lock-on spin, or with some glitchy planetoids like that bouncing ball), but they merely send you at the start of the level. However, it is painfully played straight under some circumstances. In the final level in front of Bowser, no less, where you can cause it to freeze before the final confrontation with him by managing to go up to him before the EventFlag that activates the meteor shower, and then try to activate said Event Flag. [[http://www.youtube.com/watch?v=REn7iKs7Vzs&feature=relmfu It's possible.]]
* GameplayAndStorySegregation: In the NewGamePlus, there are ''two'' Luigis; the one you play as, and the one you don't.
* GangplankGalleon: Deep Dark Galaxy hosts a pirate ship that shows up in several missions.
* AGodAmI: [[AttackOfThe50FootWhatever Not quite as literal]] as in [[VideoGame/SuperMarioGalaxy2 the sequel]], perhaps, but Bowser has ''definite'' shades of this trope in this game. Seriously, he's trying to [[spoiler:'''''destroy the universe''' so he can recreate it as his own galactic empire''. With Princess Peach as his (probably unwilling) queen.]] Granted, [[spoiler:it blows up in his face at the end (rather literally, too)]], but then [[spoiler:the universe nearly gets destroyed in the aftermath anyways]].
* GratuitousEnglish: The galaxies all had English names even in the original Japanese version. A few of them stayed the same, but most were changed despite the fact none of them really sounded very Engrish-y and (for instance, Melty Molten Galaxy was called Hell Prominence Galaxy in the Japanese version).
* GravityScrew:
** The second mission of the Dreadnought Galaxy has platforms going up, upside down and sideways at various points along a route where Mario is being fired at by various cannons.
** Gravity Walls have the power to control the direction of gravity. They appear in several galaxies, most notably in Bowser's Dark Matter Plant, where they give you four directions of gravity!
* GravitySucks: The sizes of some of the black holes are pretty ridiculous by astronomy standards...
* GreenHillZone:
** The first planet of Gateway Galaxy is grassy and somewhat flowery.
** The first planet of Good Egg Galaxy has some grassy elements.
* GuideDangIt: The Cosmic Comet races become much easier once you learn the technique to get a speed boost at the beginning; in fact, this speed boost is practically ''required'' to beat Cosmic Luigi. The only problem? The game not only does not tell you how to get it, it doesn't even tell you it ''exists''.
* HailfirePeaks: Freezeflame Galaxy combines LethalLavaLand with SlippySlideyIceWorld. It has one icy planet, one lava planet, and one with elements of both.
* HaveANiceDeath: If you get to the end of the Battlerock or Dreadnought Purple Comet missions without all the purple coins, the Gearmo will mock you for not trying hard enough and then take away one of your lives.
* HeavySleeper: The yellow Toad is often seen sleeping, and even sleeps in the snow in [[HailfirePeaks Freezeflame Galaxy]].
* HelpfulMook: Plenty! Cataquacks, Koopas, Bob-ombs, Bullet Bills, and green Topmen, to name a few.
* {{Homage}}: What with the tiny planets, way of slinging around space, and the plot of the storybook (not to mention Rosalina herself), the whole thing seems to be inspired by ''Literature/TheLittlePrince''.
* HornetHole: Honeyhive and Gold Leaf Galaxies. At least the bees are friendly.
* HubLevel: The Comet Observatory in the first game is probably the most rudimentary example yet in the Mario series; all it does is connect the various worlds, with no secrets or bonus Stars of its own, unlike ''VideoGame/SuperMario64'' or ''[[VideoGame/SuperMarioSunshine Sunshine]]''.
* AnIcePerson: Ice Mario, who's literally made up of ice. He can skate on both water and [[ConvectionSchmonvection lava]], creating a hexagonal block of ice where ever he skates.
* InCaseOfBossFightBreakGlass:
** Megaleg is defeated by making Bullet Bills break the glass cage
** To defeat an Undergrunt Gunner, Mario can ground pound on the cockpit, which is made of glass.
* IncendiaryExponent: Fiery Dino Piranha is a fiery version of Dino Piranha, the first boss in the game.
* InfiniteOneUps: There are several 1-up mushrooms scattered around the observatory hub which respawn if you enter a door and come out again, not to mention the frequent letters you get from Peach containing five 1-up mushrooms each (or 20 if you're Luigi.)
* InsectQueen: Queen Bee or the Honey Queen is the queen of all bees in the universe, and dresses in appropriate regalia. She's also playable in ''VideoGame/MarioKart 7'', where she is [[YourSizeMayVary decidedly smaller.]] She's probably the only KingMook (or King NPC) in the Marioverse that's female, as opposed to King Bob-omb, King Goomba et al.
* ItsUpToYou: [[DoubleSubversion Double subverted]]. Hey, looks like Mario doesn't have to get all the Stars himself. Luigi and the Toads are going to help him! But then they get captured or stranded, so in the end, you still have to do all the missions, same as if they weren't helping you.
* JawsFirstPersonPerspective: The battle with Kingfin opens with one.
* JustBeforeTheEnd: [[spoiler:The ''entire universe'' is destroyed]]. Sure, [[spoiler:everyone gets reincarnated]], but still, [[spoiler:''everyone dies'']].
* KingMook: Several. Examples include Baron Brrr, Topmaniac, and Major Burrows, who are respectively King Mooks of Li'l Brrrs, Topmen, and Undergrunts.
%%* KirbyDots
* KnightOfCerebus: Surprisingly, Bowser. Whenever he appears, the atmosphere gets much more tense.
* LavaAddsAwesome: [[LethalLavaLand Melty Molten Galaxy]] is the last major galaxy to be unlocked in a dome, and it's pretty epic.
%% LeapOfFaith does not apply because it's possible to see the destination when you jump.
* LethalLavaLand:
** [[HailfirePeaks Freezeflame]] Galaxy has a planet that consists of a large round sphere of cooled magma. Its center has a large fissure filled with molten lava, and this is where Mario will look for the Power Star.
** Melty Molten Galaxy is made completely from lava and rock.
* LevelAte:
** The Sweet Sweet Galaxy is mostly made of cakes and biscuits.
** "Bouncing Down Cake Lane" in Toy Time Galaxy features oversized cakes, chocolate bars, an ice cream cone, popsicles, lollipops, and huge ice cubes.
* LostWoods: Honeyhive and Gold Leaf, which are a bit more whimsical than your standard Lost Woods, but they do have giant bugs, lots of bees (including a power-up), and in Gold Leaf, rabbits. Enemies that are standard fare for these worlds appear too, like Wigglers and Monty Moles.
* MacroZone: The Toy Time Galaxy features many huge toys.
* MadeOfExplodium:
** Airships, Megaleg, Mecha Bowser, some bosses and enemies... and apparently Kingfin. Yes, an exploding, semi-biology-fail, skeleton ''shark''.
** In Battlerock Galaxy in particular, whenever Mario does a mission that requires him to go inside the Battlerock, an explosion inexplicably occurs whenever he leaves it.
* MadeOfIron: [[spoiler:Bowser gets punched right into a star at the center of the galaxy, and [[UnexplainedRecovery then shows up unscathed in the next cutscene lamenting the collapse of his empire]]. And then dies. And then wakes up in Peach's front yard.]]
* MeaninglessLives: It's pretty easy to stock up on lives. Good thing, since you start with 4 lives whenever you begin playing (regardless of how many you had when you finished your last session).
* MilesGloriosus: The self-appointed leader of the Toad Brigade. One of the other Toads {{lampshade|Hanging}}s this. In the [[spoiler:Grand Finale Galaxy]], upon learning that the captain is [[spoiler:being promoted to Royal Guard Commander]], one Toad says "But the leader is the least brave of all!"
* MoonRabbit: Just in case you're wondering why there are rabbits living in planetoids.
* MultiStageBattle: The first two thirds of the final battle against Bowser take place on two different planets; the third and final stage takes place inside a star.
* MusicalGameplay: Coins that pop up out of blocks or bushes will have their usual coin SFX be in tempo and harmony with the backing music. Additionally, when fighting King Kaliente, every time you hit one of the coconuts (or it hits him) a musical cue plays.
* MutuallyExclusivePowerups: Most combinations of the power-ups in the game (Fire Flower, Ice Flower, Spring Mushroom, Bee Mushroom, Boo Mushroom, Red Star and Rainbow Star) are impossible. Attempting to combine them will result in either the old power-up losing its effect or Mario kicking away the new power-up.
* MythologyGag: The red shells [[VideoGame/MarioKart home in on nearby enemies.]]
* NeverSayDie: [[spoiler:In Rosalina's storybook, when it's revealed that Rosalina's mother is dead, it's described as "She's sleeping under the tree on the hill".]]
* NewGamePlus: Getting all of the stars with Mario [[UnlockableContent unlocks Luigi]], and lets you play through the game again with him. He runs faster and jumps higher than Mario, but has less traction and is flung farther when an enemy touches him. He also loses extra oxygen when spin-boosting through water. And, his Cosmic Comet races are harder.
* NinjaPirateZombieRobot: Kingfin is a skeletal shark. That summons robot fish.
* NoDamageRun: The daredevil comets force you to complete a challenge without taking any damage. Usually it's redoing a boss fight, but one of the more sadistic ones - "Lava Spire Daredevil Run" in Melty Molten Galaxy - forces you to replay an entire level like this, namely, the "The Sinking Lava Spire" mission. There's also the second segment of "Scaling the Sticky Wall" in Honeyclimb Galaxy, when meteors can, in a single hit, rob you of your bee suit, and send you falling to your death by black hole.
* NobleDemon: The Spooky Speedster keeps his word and hands over the Power Star when you beat him in the races.
* NominalImportance: For some reason, the English translation didn't give names to any Lumas, while the original Japanese (which called them Chikos) did indeed have names for some of them. You know the Luma that grants Mario's ability to spin? The one that Rosalina introduces with the line, "To save your special one, you'll need to power to travel through space. Luma can give you this power. I will entrust you with his care"? He is named Tyke in the Japanese version. They also didn't mention the name of the black/dark brown Luma who is always at Rosalina's side and in the observatories. His name is Polari, after the star Polaris. This oversight makes the storybook a tad confusing in the English version, since [[spoiler:upon meeting the Lumas for the first time, Rosalina makes a point of thinking up names for all of them.]]
* NotCheatingUnlessYouGetCaught: In the second mission of Beach Bowl Galaxy, "Passing the Swim Test", you have to retrieve a golden shell in the ocean and bring it back to the coach in order to pass the test and get the Power Star. However, there aren't any golden shells lying around on the ocean floor. One of the other penguins eventually clues you in that the actual way to pass the test is to find a penguin carrying a shell and steal it from him.
* NotSoHarmlessVillain: Dino Piranha is the first boss of the game and a pretty easy one at that. The [[IncendiaryExponent fiery version]] is ThatOneBoss for many, using the same attacks as the first one, as well as using its [[PlayingWithFire fire powers]] [[TakingALevelInBadass offensively and defensively]].
* NumberTwo: Polari, the black Luma who's always at Rosalina's side or in the map domes, appears to fulfill this role aboard the Cosmic Observatory.
* OminousFloatingSpaceship: Bowser uses a saucer to laser-carve out the ground underneath Peach's castle and carry it away, kidnapping Princess Peach in the process.
* OminousLatinChanting: Bowser's battle theme invokes this for both the [[http://www.youtube.com/watch?v=RJqrQJr_vrc&feature=related regular boss battles]] and his [[http://www.youtube.com/watch?v=lIuvjG3Egjo final boss battle]], although no actual words are spoken; it's a choir singing "ah" and "ooh" in the ''style'' of ominous Latin chanting.
* OneHitKill: Thwomps and Tox Boxes can flatten Mario, which always kills him instantly.
* OneHitPointWonder: The daredevil challenges reduce Mario's max health to one unit, which means that any damage will kill him.
* OpeningTheSandbox: If you collect all the Stars in the galaxies as they become accessible to you, you'll very quickly reach the point where you can take the remaining Star missions in pretty much any order you want.
* OxygenatedUnderwaterBubbles: The underwater bubbles restore Mario's air meter instantly when he gets them.
* PaletteSwap: Gold Leaf Galaxy is an autumn-colored mirror image of Honeyhive Galaxy.
* PalmtreePanic: Beach Bowl and Sea Slide Galaxy have beach areas with water, sand, scales, and palmtrees.
* PassThroughTheRings: Both times you meet Guppy, he asks you to swim through eight rings.
* PivotalBoss: King Kaliente, Tarantox, Bouldergeist, and the Undergrunt Gunner all stay in one spot, pivoting and attacking Mario.
* PowerUpMagnet: One of the uses of the pointer is attracting Star Bits.
* RacingMiniGame: Several. To start with, there are the four Cosmic Comet races. In two levels ("A Very Spooky Sprint" in Ghostly Galaxy and "Racing the Spooky Speedster" in Boo's Boneyard Galaxy), you race a helmet-wearing Boo to a Power Star. You also race a group of penguins in "Faster Than a Speeding Penguin" in Sea Slide Galaxy, and there are at least four levels in which you encounter rabbits who want you to chase them. Then there's the "Surfing 101" mission in Loopdeeloop Galaxy and the "The Galaxy's Greatest Wave" mission in Loopdeeswoop Galaxy, in which you have to make three laps around a watery course on a manta within a (fairly generous) time limit. The game designers apparently think players can't get enough racing.
* RainbowSpeak: In dialogue, important words are often highlighted with various colours.
* RecurringBoss: Topmaniac has to be fought four times: twice in regular battles ("Topmaniac and the Topman Tribe" in Battlerock Galaxy and "Revenge of the Topman Tribe" in Dreadnought Galaxy), once in a daredevil battle ("Topmaniac's Daredevil Run" in Battlerock Galaxy), and once as part of a speed run ("Topman Tribe Speed Run" in Dreadnought Galaxy). Kamella and Bowser have to be fought three times each (Kamella in "Kamella's Airship Attack" in Space Junk Galaxy, "The Underground Ghost Ship" in Deep Dark Galaxy and "Ghost Ship Daredevil Run" also in Deep Dark Galaxy, Bowser in "The Fiery Stronghold" in Bowser's Star Reactor, "Darkness on the Horizon" in Bowser's Dark Matter Plant and "The Fate of the Universe" in Bowser's Galaxy Reactor) and there are several other bosses you have to fight twice.
* RecycledINSPACE: ''VideoGame/SuperMario64'' IN SPACE!
* {{Reincarnation}}: A major theme of the game. Lumas are born from star dust, and grow into stars, moons, and planets, the latter of which have people on them. Eventually, they decay and crumble back into star dust, which goes on to create new Lumas. When you add in the ending, this game looks very, very Buddhist.
* RemilitarizedZone: The airships from ''VideoGame/SuperMarioBros3'' show up in a couple of levels. Battlerock and Dreadnought Galaxies also have shades of this.
* RidiculouslyCuteCritter: Lumas. You can feed them Star Bits and they'll thank you and spin around (one of the little ones responded with "Happy!"). You can't help but {{Squee}}!
* RingOutBoss: Topmaniac is defeated by jumping on it, which forces it to retract its spikes, then spinning into it to make it hit the [[BossArenaIdiocy electric fence around it]].
* RiseToTheChallenge: "The Sinking Lava Spire" in Melty Molten Galaxy. "Sunbaked Sand Castle" in Dusty Dune Galaxy is an unusual example; Mario is trying to make it to the top of a tower before it fills up with sand, but the game [[InterfaceScrew turns the controls upside down]], so it appears that the ceiling is trying to crush Mario before he gets to the bottom.
* RoyalWe: The Queen Bee speaks this way.
* RuleOfCool and RuleOfFun: This is definitely one of the least realistic games in the series, what with all of the ArtMajorPhysics and stuff. All in the name of fun, though.
* SaveThePrincess: Acceptable thanks to the GrandfatherClause, because it would not be Mario if it wasn't required.
* SayMyName: Peach screaming for Mario's help. It doesn't help that, outside of her letters, it's her ''only line in the game''.
-->'''Peach''': MAA-REE-OOO! HELP ME!
* SceneryAsYouGo: The platform maze in the "Pull Star Path", "Pull Star Path Speed Run" and "Purple Coin Spacewalk" missions in Space Junk Galaxy, as well as the ice bridges in Bowser's stage.
* SceneryPorn: Just ''look'' at some of the space backgrounds. They look absolutely amazing, and in 480p no less. For example, in the first level of Melty Molten Galaxy, there's a sequence which consists of Mario shooting through several launch stars in a row. The main point of the sequence seems to be to show off the impressive graphics of the volcano level.
* SciFiWritersHaveNoSenseOfScale: Those are ''not'' galaxies, those are clusters of asteroids, or small moons at ''best''. And there is no reason to assume Mario is doing more than visiting the part of the galaxy relevant to him but each gateway looks more like it's selecting from a solar system. Also, along with that, Bowser Jr.'s airship armada can not be viewed that huge a couple of thousand miles away, as that "galaxy" is smaller than even the other galaxies in the game..
** ToonPhysics aside, it might have been more sensible for each of the galaxies to be called 'solar systems,' each found within the same galaxy. There's also a few mentions of Bowser setting up shop in the center of the universe, [[ArtisticLicenseAstronomy which isn't a place]] (or rather, [[MindScrew is every place]]). 'Center of the galaxy' would have worked much better.
* SelectiveGravity: No matter how [[GravityScrew weird the gravity is]], certain objects like coins and platforms can float.
* SelfImposedChallenge: Getting all 150 purple coins in "Luigi's Purple Coins" in Toy Time Galaxy or "Purple Coins on the Puzzle Cube" in Gusty Garden Galaxy (only 100 are required for the star). [[http://www.youtube.com/watch?v=inPSGDUsn24 Yes]], [[http://www.youtube.com/watch?v=5PraZGgdwRU&annotation_id=annotation_991106&feature=iv both]] are actually possible! Not enough for you? Here's [[http://speeddemosarchive.com/forum/index.php?topic=7615.0 a bunch more!]] The developers also made it so that getting Starshrooms are optional.
* {{Sequel Escalation}}: This game is more of a successor to VideoGame/SuperMario64 than VideoGame/SuperMarioSunshine, and it begins with Bowser stealing Peach's castle. Super Mario 64 took place ''entirely'' in and around that castle, and Bowser just hoists it off like it was nothing. That's a clear sign that the stakes are much higher this time.
* ShiftingSandLand: Dusty Dune Galaxy.
* ShipTease[=/=]PairTheSpares: Luigi gets some with Rosalina [[spoiler:in his NewGamePlus, including a 100% picture together in the same vein as Mario and Peach's]], [[ReplacementScrappy much to the chagrin of Princess Daisy fans.]]
* ShoutOut:
** The planet shaped like a [[{{Franchise/Pokemon}} Poké Ball]] in Buoy Base Galaxy. It even ''opens'' like one.
** Also, in Space Junk Galaxy, Mario walks on [[{{Franchise/Pikmin}} Olimar's ship]].
** In Rolling Gizmo Galaxy, there's a fairly well-hidden [[Franchise/TheLegendOfZelda Rupee]] made of blue star bits.
* SingleBiomePlanet: Tons of them.
* SlidingScaleOfLinearityVsOpenness: The levels are mostly linear compared to ''SuperMario64'' and ''[[SuperMarioSunshine Sunshine]]''.
* SlippySlideyIceWorld:
** A planet in [[HailfirePeaks Freezeflame Galaxy]] is a snowy, rocky mountain with ice and cold water.
** An section of [[ToyTime Toy Time Galaxy]] features [[LevelAte popsicles]] and ice cubes.
* SpaceDoesNotWorkThatWay: This game fails physics in so many ways [[Administrivia/ConversationInTheMainPage it's better not to discuss them here]].
%% SpaceIsMagic does not seem to apply.
* SpaceZone: Naturally, everything in the game can be considered this because it takes place in outer space. Space Junk Galaxy is the best example. It contains discarded space junk, including old rocketships and floating debris.
* SpringCoil: The dreaded Spring Mario powerup, which wraps a spring around Mario.
* StealthPun: The ''Dirty'' Tricks of Major Burrows. As in, the dirt that he digs through! Most of the levels are like this to some extent.
* SurpriseCreepy: The whole game is level after level of pure joy, but at the end, [[spoiler:the universe ends and the Lumas [[HeroicSacrifice give themselves up to bring it back]]]].
* SuspiciousVideogameGenerosity: There is always a Life Shroom just before a boss or difficult section, often sold by a Luma Shop. And a MusicalSpoiler where it changes to the 'Tension' theme. Both of these are in the sequel, too.
* TacticalSuicideBoss: Several examples. The Bomb-Boos that Bouldergeist spits out are the only way to defeat him. Same deal with King Kaliente and the coconuts he occasionally lobs at you. If he'd just stick to fireballs, he'd be invincible.
* TennisBoss: King Kaliente is defeated by reflecting his coconuts at him.
* ThreateningShark: Kingfin, which is basically ''a skeletal shark''.
* ThrowTheMookAtThem: Bouldergeist, a ghost that encases itself within stone. Normally it would be invincible to Mario's attacks. However, during the fight it will occasionally throw a black rock at Mario, which will become a Bomb Boo, which in turn Mario can use against the Bouldergeist to break apart his stone casing. When it reaches its vulnerable phase, [[IdiotBall guess what it still intentionally spawns?]]
* TimedMission: The speedy comet challenges, as well as the ammo depot mini-games have time limits. Some of the purple coin missions are timed as well.
* TitleScream: Just like the rest of the 3-D platformers, Mario screams the name of the game whenever you start it up.
* TookALevelInBadass: Bowser. In previous titles, his goal is just to kidnap Peach. In Galaxy, capturing Peach seems to just be a bonus for him; his real goal is ''the conquest of the entire universe.'' (See AGodAmI above).
* ToyTime: Toy Time Galaxy is the TropeNamer, and features oversized toys like a toy train on a train track.
* TrueCompanions: The overarching theme of the storybook is how Rosalina and the Lumas are like this.
* TunnelKing: The Undergrunts and Major Burrows, who are mole-like creatures, are pretty good at digging.
* TurnsRed: Pretty much every boss in the game gains new attacks once you get a couple of hits on them.
* TheUnfought: The UFO Bowser uses from the opening sequence simply lifts Peach's castle into the air and into space. It also appears in the cutscene just before the final level and during the ending. It has absolutely no impact on the gameplay though.
* UnderTheSea: Three main galaxies (Beach Bowl, Sea Slide, and Deep Dark) and four mini-ones (Buoy Base, Drip Drop, Bigmouth, and Bonefin).
* UnlockableContent: Getting all of the Stars with Mario [[UnlockableContent unlocks Luigi]], and lets you play through the game again with him. He runs faster and jumps higher than Mario, but has less traction and is flung farther when an enemy touches him. He also loses extra oxygen when spin-boosting through water. And, his Cosmic Comet races are harder.
* UnmovingPlaid: Cosmic Mario has Mario's character model with an unmoving texture of a night sky.
* UnderwaterBossBattle: The battle against Kingfin, a huge skeletal shark, takes place under water.
* UnrealisticBlackHole: Several are localized around planets and are only a couple of feet in diameter. And the black holes are extremely picky about what they want to suck in. In real life, all those black holes in Honeyhive Galaxy (for example) would suck in the ''entire level and everything in it'', not just Mario!
* VariableMix: All over the place:
** Gateway, Battlerock, Beach Bowl, Buoy Base, Sea Slide, and Freezeflame Galaxies all feature instrument variations in their background tracks depending on what you're doing or where in the stage you're at. Other tracks that change up at will include stage select domes, the ball rolling minigame, rabbit chasing, and any boss fight with Bowser. That a significant number of these tracks were recorded by a full orchestra makes the switchovers all the more impressive.
** Additionally, no matter what stage you're in or what song is playing (including Rainbow Star, Fire Flower, or Ice Flower tracks), touching a Sling Star adds a matching harp to the music, with the arpeggio varying in intensity with how big the star is.
* VerbalTic: The rabbits have one, boiyoing!
* TheVeryDefinitelyFinalDungeon: Bowser's Galaxy Reactor, taking place in the ''center of the universe.''
* VideoGameCrueltyPotential: During one mission in Space Junk Galaxy, you'll encounter a Toad trapped in a sling pod. To progress, you have to get him out of the sling pod so you can use it yourself, but the game progresses whether you fling him to a safe spot or kill him by flinging him out into space. Many players get a sadistic kick out of doing the latter. (Not that it ultimately matters, since he shows up again on the Comet Observatory either way.)
* VoiceGrunting: In place of the full VoiceActing from ''VideoGame/SuperMarioSunshine''.
* WakeUpCallBoss: Bugaboom is the first boss who's likely to give players a challenge. He isn't exactly ''hard'', but if you don't have your jump timing down yet, he can be very tricky to beat.
* WaterIsBlue: The water has a weak tint of blue, which is easily visible in galaxies like Loopdeeloop and Beach Bowl.
* WeirdMoon: Sand Spiral Galaxy has a moon that generates ''light''.
* WhatHappenedToTheMouse:
** The flying saucer seen in the opening, which is equipped with lasers capable of ''slicing through the ground effortlessly'', and which is obviously not from the World of Mario, is never mentioned after the opening.
** In the storybook, what happened to [[spoiler:the girl's father and brother]]?
*** [[spoiler:Presumably, they died like the girl's mother did. The girl was gone for a long time after all.]]
** At the start of the game, Peach tells Mario to come to the Star Festival because "there's something I'd like to give you". We never find out what that something is. It may be the Luma.
* WhatTheHellPlayer: In Buoy Base Galaxy, if you talk to the Gearmo after destroying the weight that's keeping the fortress from rising to the surface, he says, "You destroyed the weight! So you just go around breaking stuff, eh? You think that's OK? Breaking stuff?"
* WideOpenSandbox: You only have to get half the Stars in the game to be able to take on the final boss, giving players who aren't going for HundredPercentCompletion a lot of leeway in deciding which missions to play.
* WorldShapes: There are many others, not just spherical ones.
* XRaySparks: In addition to the standard usage, if Mario is killed by a shock, he dies as [[DemBones just a skeleton]]. If Mario hits a coin during the electrocution animation, he's brought to one point of health and gets his flesh back, saving him but looking incredibly unnerving.
