The fourth ''VideoGame/PaperMario'' game, after ''VideoGame/SuperPaperMario'' and before ''VideoGame/PaperMarioStickerStar''. Okay, it's actually a fanfic, not a game, but it is a completely original Mario adventure in the ''VideoGame/PaperMario'' style.

It starts out much like ''[[VideoGame/PaperMarioTheThousandYearDoor Thousand-Year Door]]'' does, with Mario learning that Peach wants him to join her on a trip to a far-off land, Chronoside. A Goomba thief steals Mario's hammer, and Mario chases the the thief into the Temple of the Sun. There, they witness King Shroude kill the six Guardians of Day in an attempt to create a world of perpetual night, separating Chronoside into Dayside, where it's always Day, and Nightside, where it's always night. Now Mario must recover the six Sun Souls and find six new Guardians of Day in order to reunite the two worlds.

The story can be found [[http://www.fanfiction.net/s/5389528/1/Paper_Mario_The_Temple_of_the_Sun here.]]

(Note that whenever a reference to a chapter is made in the examples, this refers to the chapters of the game, not the chapters of the fanfic. Like all ''Paper Mario'' games, ''Temple of the Sun'' has eight chapters.)
----
This fanfic provides examples of:

* AcquiredPoisonImmunity: [[spoiler:Maizee]], who's been trapped in the Poisoned Factory so long that [[spoiler:she's]] grown immune to the effects of even the strongest toxins.
* ActionGirl: Hanner
** ActionMom: [[spoiler:Maizee]]
** DarkActionGirl: Rizz and her minions, Sall and Bess. Also Maizee [[spoiler:before her Heel Face Turn.]]
* AntiHero: There really isn't much that's heroic about Goomblaine, who really only got roped into helping Mario out because it was his fault that Mario was in the Temple of the Sun when King Shroude attacked the Guardians of Day. [[spoiler:Not until he becomes the Master of Day, anyway.]]
* TheAtoner: [[spoiler:Maizee]] post-HeelFaceTurn.
* BarBrawl: Naturally started by Goomblaine.
* BigBad: King Shroude
* BrainwashedAndCrazy: [[spoiler:Dulia. Actually, Diavelli can do this to all of his performers.]]
* BreatherLevel: Chapter 5 takes place at the Poisoned Factory. Chapter 6 takes place at the Seashell Hotel. [[spoiler:Subverted when the hotel is filled to the brim with Darkstriders.]]
* CallBack: Frequently makes references to the first three games. Sample dialogue:
-->'''Snatchel:''' Well, sorry Mario, but I can't reach ''that'' far. Huh, it's kind of a shame we can't just turn into paper airplanes, ain't it?
-->'''Mario:''' [[VideoGame/PaperMarioTheThousandYearDoor What? …Oh, yeah. No, that'd just be silly.]]
** Hot Sauce that creates a huge explosion when mixed with Orange Juice: probably a reference to the Nitro Honey Syrup from ''TTYD''. Appears in the same chapter, too.
** Two come from Peach, where she references what the villians of the past two ''Paper Mario'' games wanted to do with her.
-->'''Peach:''' Let me guess- you're trying to resurrect and ancient demon, and you need my body for it to possess? Or maybe you're trying to destroy the universe, and you need me to marry someone in order to create an interdimensional rift that will swallow everything up?
-->'''Shroude:''' You have a VERY active imagination Princess.
* CastingAShadow: The Darkstriders
* CircusOfFear: Starshine Circus
* [[spoiler: CorruptPolitician: Mayor Bulbin turns out to be behind the Poisoned Factory, as well as the one responsible for sending Maizee after the Sun Souls.]]
* ConversationalTroping:
-->'''[[spoiler:Maizee]]:''' What on earth is he doing?
-->'''Hanner:''' You clearly don't know the first rule of adventuring. Open every chest you find.
-->'''Dulia:''' I thought the first rule of adventuring was to go into every house you find, because for some reason the people living there probably won't care and might actually give you stuff. Am I the only one who's noticed that?
-->'''Hanner:''' Yeah, that's probably a rule too.
* CowboyEpisode: Chapter 3.
* CuteBruiser: Stubba is just a kid (six years old), but he serves the role of TheBigGuy in the party.
* DarkerAndEdgier: A logical progression given that each game in the series is a bit heavier than the previous one, but Chapter 4 is where things start getting really dark. Then Chapter 5 is ''even darker''.
* DeceptiveDisciple: The leader of the Mouser Gang turns out to be Bronson, the deputy of Golden Spur Ranch. The operation at Mustard Mines was just a ploy to get Sheriff Snatchel to leave town and leave Bronson in control.
* DeconstructionFic: Even despite Paper Mario being big on deconstruction to begin with. Look no further than Mario's character arc and [[spoiler:Peach's ultimate role in the story.]]
* DividedWeFall: Happens in Chapter 6 when the Darkstriders convince Ferdinand that he's unwanted.
** Happens again in Chapter 7 when [[spoiler:Goomblaine quits.]]
* DoesThisRemindYouOfAnything: [[spoiler: Goomblaine's parents being murdered over religious reasons.]]
* TheDragon: Jaff.
* {{Expy}}: Although with the exception of Goomblaine (Goomba) each of Mario's partners is of a race that had not been one of his partners in a previous game, most of them serve the same purpose.
** Hanner, the Hammer Bro, serves the "hit distant switches" function of Kooper/Koops
** Stubba, the Clubba, breaks through cracked walls just like Bombette and Bobbery
** Snatchel, the Bandit, serves the "grab distant items" function of Kooper and Koops, as well as Ms. Mowz's treasure-sensing ability.
** Dulia, the Duplighost, conceals the party just as Bow and Vivian did (with the addition of an ability to disguise them as something else)
** [[spoiler:Maizee, the Crazee Dayzee]], is the only one without a clear counterpart from the first two games; her ability is disabling traps and other hazards.
** Ferdinand, the Bumpty, can carry Mario across gaps like Parakarry and Yoshi.
** Outside of the partners, [[MeaningfulName Diavelli]] seems awfully reminiscent of [[VideoGame/PaperMarioTheThousandYearDoor Grubba]].
*** The fact that he runs a ''carnival'' also makes him seem a bit like [[Literature/SomethingWickedThisWayComes Mr. Dark]].
** The sixth chapter takes place at the Seashell Hotel, reminiscent of ''SuperMarioSunshine'''s Sirena Beach.
* FaceHeelTurn: [[spoiler:Goomblaine]] briefly has one of these in Chapter 7.
* FantasticRacism: Mario himself goes through this twice, first when he meets Stubba (a Clubba), due to the status of both [[VideoGame/PaperMario64 Tubba Blubba]] and [[VideoGame/PaperMarioTheThousandYearDoor Grubba]], and then again when he meets Dulia (a Duplighost), due to [[spoiler:Doopliss stealing his identity in ''Thousand-Year Door'']]. Hanner even calls Mario out on it being "another Stubba thing" when she sees his reaction to learning that his fifth partner is to be a Duplighost. He's also a lot quicker to get over it with Dulia, precisely ''because'' remembering the loneliness he felt during that incident allows him to see that Dulia's feeling the same way.
** Of course, all of this isn't actually racism, it's more like [[NightmareFuel deep-seated fear]].
* GotMeDoingIt: After TheReveal with Bronson, Hanner calls him a "low-down, dirty bilge rat", then says that she's been here too long when everyone turns and stares.
* {{Greed}}: Clefford.
* HeelFaceTurn: [[spoiler:Maizee]] turns out to be one of the Guardians.
* HoistByHisOwnPetard: After the Abominable Snowwoman boss of Chapter 2 fails to defeat the heroes, the Darkstriders try to do the job themselves...and are promptly beaten up by said boss, angry at them for lying to her about Mario being responsible for the rockslides.
** [[spoiler:Bulbin]], the Chapter 5 boss, fights the party on a bridge above a pit of acid, and spends much of the battle trying to break the arena and send them into the acid. This isn't BossArenaIdiocy because they defeat him ''before'' the bridge breaks, but after the battle ends with the boss still alive and [[spoiler:Maizee]] [[IfYouKillHimYouWillBeJustLikeHim refuses to kill him]], the bridge breaks and he plummets to his doom.
* HowDareYouDieOnMe: Snatchel takes a flame attack from [[spoiler:Blackout Bowser]] for [[spoiler:Maizee]], and is slower to recover after the battle than the rest of Mario's partners. Cue the SlapSlapKiss.
* IfYouKillHimYouWillBeJustLikeHim: Once [[spoiler:Bulbin]] is rendered helpless, Mario gives [[spoiler:Maizee]] the chance to finish him. She refuses. Then the floor collapses beneath him and he falls into the acid pit below.
* IllBoy: Daymien
* InterspeciesRomance: Benny (Boo) and Dulia (Duplighost), Snatchel (Bandit) and [[spoiler:Maizee (Crazee Dayzee)]].
* IronicFear: Benny is a Boo who is easily frightened.
* IShallTauntYou: How Mario eventually manages to beat [[spoiler:Blackout Bowser]].
* JerkassWoobie: [[spoiler: Goomblaine turns out to be this in Chapter 7.]]
* [[LetsYouAndHimFight Let's You And Her Fight]]: The Chapter 2 boss is spurred into fighting Mario and friends by the Darkstriders convincing her that Mario was responsible for the rock slides. When she finds out that this isn't true, she attacks the three of them.
* LimitBreak: As a nod to past Paper Mario games, Mario receives a Special Move every time he recovers a Sun Soul. The Special Moves are listed below in the order in which they're learned.
** [[HealingFactor Second Wind]] heals Mario and his partners in dire situations with a refreshing breeze, like Refresh/Smooch and Sweet Treat/Feast.
** [[TimeStandsStill Freeze Frame]] briefly stops enemies in time using a green frame of light, similarly to Time Out and Clock Out.
** [[StatusBuff Miracle Grow]] causes Mario and his partners to grow huge and thus have their Attack raised, like Power Lift.
** [[KillItWithFire Fire Away]] attacks all enemies with bolts of fire, directly dealing damage like Star Storm and Earth Tremor.
** [[OneHitKill Clean Sweep]] has a [[BigLippedAlligatorMoment giant broom sweep all enemies out of the fight]] and instantly defeat them, like Up & Away and Showstopper.
** [[ResetButton Square One]] literally flips back the pages of time and allows Mario to undo a battle turn that went badly. It doesn't have an analog from past games.
** [[spoiler:[[HolyHandGrenade Shine Down]] massively damages all foes with beams of light, draining Mario's and Goomblaine's energy in the process. It's comparable to Supernova.]]
** [[spoiler:[[EleventhHourSuperpower Break of Day]] gives Mario, Goomblaine, and the Guardians the power to null Shroude's invincibility, like Star Beam/Peach Beam.]]
* LoadBearingBoss: [[spoiler:Bulbin]]'s death leads to the Poisoned Factory collapsing.
* LookBehindYou: "Hey, look over there! Is that Zip Toad?"
* LoopholeAbuse: Diavelli's ''life'' contracts don't work on ghosts, for obvious reasons, allowing Dulia to fight him.
* [[spoiler:MagnificentSeven: Yeah, there are actually ''seven'' Sun Souls, not six--six for the Guardians of Day, and one for the Master of Day. King Shroude believes Peach to be the Master of Day. ''He's wrong''.]]
* MamaBear: Maizee, to the Putrid Piranhas.
** [[spoiler:More literally, her reason for opposing the heroes turns out to be because her son was threatened by Bulbin.]]
* MeaningfulName: The hub of the game is Soluna Town.
** Diavelli, the boss of Chapter 4. Do ''not'' sign [[DealWithTheDevil any contract he offers you]].
* MostCommonCardGame: The game actually being played is called Faro, but Stubba naturally asks if Mario is playing Crazy Eights.
* MySpeciesDothProtestTooMuch: In addition to the usual "partners are heroic versions of enemies", Snatchel, a ''Bandit'', is sheriff of Golden Spur Ranch.
* MythologyGag: Yes, the crew gets to transform into their eight-bit selves again. Given how few of Mario's partners even ''existed'' in the 8-bit era, this would likely require some brand new sprites.
* [[spoiler: NarratorAllAlong: Goomblaine.]]
** Dialogue from the last chapter implies that [[spoiler: Goomblaine]] may actually be the narrator from the four ''[[VideoGame/PaperMario Paper]] [[VideoGame/PaperMarioTheThousandYearDoor Mario]]'' [[VideoGame/SuperPaperMario ga]][[VideoGame/PaperMarioStickerStar mes]]
* NeverSayDie: Just like in ''VideoGame/SuperPaperMario'', references are made to "ending someone's game" rather than killing them, though occasionally death will be mentioned.
* NiceJobBreakingItHero: Only once the six new Guardians of Day were united with their Sun Souls was the [[spoiler:seventh Sun Soul activated and the new Master of Day empowered.]] Poor Mario...
* NonSequiturThud: A Mouser does this in Chapter 3. Clefford also has some non sequitur sleeptalking in Chapter 2.
* PaletteSwap: {{Lampshaded}} in Chapter 8.
** PartyInMyPocket: Also lampshaded in Chapter 8, but unlike in other Paper Mario games, it's defied.
* PowerUpFullColorChange: [[spoiler:Blackout Bowser]]
* [[spoiler:PrinciplesZealot: The Guardians are somewhat of a religion in Chronoside. Goomblaine's parents were nonbelievers. They had their house burned down and were killed by religious zealots. Goomblaine stopped believing in the Guardians after that, feeling that if they were real, they wouldn't have allowed that to happen.]]
* PsychoSerum: Maizee's mutant Putrid Piranhas are dosed up with successively more of this. By the end, they're so insane that they no longer even recognize Maizee and attack her. [[spoiler:Luckily she's been working with these poisons so long that [[AcquiredPoisonImmunity she's immune to them.]]]]
** And then [[spoiler:Bulbin himself]] takes it, despite knowing the risks.
* RecurringBoss: Jaff, Pell, and Nobb are fought multiple times, as are Maizee and her Putrid Piranhas.
* RippleProofMemory: Aside from Mario and Goomblaine, who were inside the Temple of the Sun when Chronoside was split, the only ones who realize that time has essentially stopped are those who are destined to become the new Guardians.
* SayingTooMuch: Mario lets slip that the reason they want to get to Mustard Mines is so they can get time moving correctly again. Turns out to have been the perfect thing to say when the sheriff holding them in prison at the time ''has'' noticed that something's wrong with time and lets them out, on the condition that they let him join them on their trip. (Of course, they have to oblige, not only because he's holding them in prison but also because the fact that he knows that time is all messed up means he's one of the new Guardians.)
** Later, [[spoiler:Maizee and Bulbin]] confront each other, and not knowing that Mario and friends are already in the same room as they are, the latter reveals his ManBehindTheMan status right before trying to kill the former.
* ShipperOnDeck: When [[spoiler:Maizee]] kisses Snatchel, Hanner's reaction is "Finally!"
* ShoutOut: When Mario finds the Zap Tap badge, Hanner says, "Awesome! A [[Videogame/{{Earthbound}} Franklin Badge]]!"
** "ATTENTION, PESKY PLUMBER! The Darkstriders and I have taken over the Palmy Balmy Beach! [[HotelMario The vacationers are now all permanent guests at one of my seven Seashell Hotels!]]" Moments later he corrects himself, as they only have one hotel.
** The scene where [[spoiler: Goomblaine comes out of nowhere and attacks Mario]] is meant to mirror [[WesternAnimation/AvatarTheLastAirbender Zuko's]] infamous subverted HeelFaceTurn.
** Ferdinand and Stubba combine their attacks, with the former calling them [[VideoGame/ChronoTrigger Dual Techs]]. Goomblaine says ItWillNeverCatchOn.
** A villager suggests that to save their home, they [[SpongeBobSquarePants should push it somewhere else.]]
* ShrinkingViolet: Dulia
* SouthernGentleman: Snatchel
* StealthMentor: [[spoiler:Maizee repeatedly helped the party from the shadows, wanting them to beat her every time and eventually free her from Bulbin's control.]] Naturally, despite having heard a confession from the ManBehindTheMan, Mario's still a little reluctant to trust [[spoiler:her]] since the last villain to claim that he'd been on Mario's side all along [[VideoGame/SuperPaperMario turned out to be the Big Bad]].
* TheStarscream: [[spoiler:Rizz]], sort of. Not actually trying to usurp King Shroude, but rather trying to undermine Jaff and take his place as TheDragon. [[spoiler:And actually ends up helping Mario at one point because she believes that he can defeat Jaff, but won't be able to defeat Shroude.]]
* SurferDude: BUMPTY BOARDERS FOREVER!
* TemporalThemeNaming: The names of the six [[spoiler:(actually seven)]] Sun Souls. There's the Dawn Soul, the Morning Soul, the Sunhigh Soul, the Meridiem Soul, the Eve Soul, and the Dusk Soul. Interestingly, they correspond with the location they're found in; for instance, the Dawn Soul is found in Fleet Forest, where it's perpetually sunrise, and the Eve Soul is near Viney Valley, where it's always early evening.
** [[spoiler:The seventh Sun Soul, having power over the other six, is the Day Soul.]]
* TerribleTrio: Jaff, Pell, and Nobb. Later Rizz, Sall, and Bess.
** ThemeNaming: All of these named Darkstriders have four-letter names with a doubled letter at the end.
*** OddNameOut: The king of the Darkstriders is named Shroude, however.
* TomboyAndGirlyGirl: After finding the third Sun Soul, Hanner says she hopes the next Guardian is a girl, because there weren't enough girls on the team. Mario points out that she isn't terribly feminine herself. Sure enough, the next Guardian is the very feminine Dulia.
* TotallyRadical: Ferdinand and the other Bumpty Boarders
* UnusuallyUninterestingSight: Like the other future Guardians, Ferdinand noticed that the sun didn't move in the sky...he just figured that everything happens for a reason and went with it.
* WallJump: Unlike in previous games, the Ultra Boots now give Mario this ability.
* [[WhamEpisode Wham Chapter]]: While ''Temple of the Sun'' is DarkerAndEdgier than most Paper Mario games starting fairly early on, Chapter 5 is where things start getting really heavy.
* WhatCouldHaveBeen: The boss of Chapter 6 was originally going to be a "big pig thing", but was changed for being too similar to Midbus from ''[[VideoGame/MarioAndLuigiBowsersInsideStory Bowser's Inside Story]]'', which hadn't been released when the story began.
* WorthlessYellowRocks: The partners mistake the Ultra Stone for this.
