* [[ContestedSequel Contested Spinoff]]: It gives ''358/2 Days'' a run for its money in this department.
* CrowningMomentOfFunny:
** [[spoiler:"Play at night!"]], if only because of how it unexpectedly [[BreakingTheFourthWall cracks the fourth wall]].
** Some of the random Balloon Letters you can get can be this, at least if you get all the jokes and references. [[http://s376.photobucket.com/albums/oo209/KrytenKoro/Avatars/ Just see for yourselves.]]
* DemonicSpiders: The block spider heartless [[spoiler: that you encounter in Data-Riku]], see the entry for Kingdom Hearts on this trope's article for more information.
* DisappointingLastLevel: The game essentially ends with you playing an hour of Chain of Memories. Vibrant interesting environments are replaced with pathetically easy single room puzzles, most of which consist of speaking to the right [=NPCs=] in the right order. On the other hand, this segment is incredibly psychological, and for some, it's the best part of the game. And the boss fight against [[spoiler:Data-Roxas]] is worth it.
* GameBreaker:
** Judgment Triad in the remake. FULL STOP. It can hit air enemies easily, has homing capabilities, is easy to aim, can hit multiple enemies, and worst of all, does such insanely high damage that almost every enemy, including ''most bosses'', will be [[OneHitKill one-shotted]] by it (and the one that isn't one-shotted will at most take 3 shots to bring down). It makes even the BonusBoss battle just all about dodging with the dodge roll, and aiming Judgment Triad. AND you can have four in your deck. The main downside is that you won't be able to have anything else in your deck, but who cares?
** Below the broken Judgment Triad is Triple Pursuit, which while not as ridiculous, is quite insane. It is a tracking Ice elemental attack that does good damage and lasts extremely long, to deal multiple hits and freeze enemies that aren't immune to it almost every time. Its ingredients? Two commands that you can buy (or get) relatively easily because one is a Basic Magic command and the other can be bought right after you complete the fourth world (and it costs a mere 12,000 munny). ''Easily'' a DiscOneNuke.
** The 30 layer labyrinth in Olympus Coliseum has powerful enemies in large numbers on lower layers. The going becomes a lot easier with Tornado Tracer. It becomes the command Breath of Zeus L2, doing high damage to all enemies for one command. Whatever isn't killed is easy to mop up with normal attacks from Hercules and Cloud. The only catch it that the ingredients to synthesize it are a bit pricy (Aero Edge + Cure, Stop, Slow or Aero to make Aerora, then Aerora + Wind Dash or Wind Tracer, total of 4,400 munny).
** Forget commands, the most broken ability in the game is [[AlwaysAccurateAttack Targeting Scope]]. The last ability on the 0/1 keyblade, it makes your basic attack automatically strike the nearest enemy, ''regardless of distance''. Walk into a room of EliteMooks, swing for five seconds, and everything dies. The best part? One of the earlier clock abilities makes every. Single. Attack. A critical hit. It's easily in the same league as Judgement Triad.
* GeniusBonus: The Metal Chocobo upgrades are all named after the chemical symbols for various "[[MeaningfulName metals]]": Fe for iron, Ag for silver, Au for gold, and Pt for platinum.
* HilariousInHindsight: Those avatars... who would ever suspect of them getting ADayInTheLimelight?... ''oh,'' right. ''TheatrhythmFinalFantasy.''
* MoralEventHorizon: Pete attempting to crush Donald and Goofy to death in Bug Blox in Hollow Bastion with absolutely no remorse and enjoying himself in the process. Thankfully Data-Sora reclaims his Keyblade and Mickey shows up too.
* NightmareFuel:
** When [[spoiler:Jafar]] takes control over time, everything goes green. [[TimedMission A timer appears.]] And there ''[[NothingIsScarier is no music whatsoever.]]'' You have three minutes to find [[spoiler:Iago]] ''three freaking times'' and stop your inevitable permanent [[AndIMustScream freezing in place for all eternity.]] Break blocks to gain more time. Kill enemies -- [[NightmareFuel enemies that will just stand there dully]] -- to gain precious seconds. But you're all alone...
** NightmareRetardant: Unfortunately, all that happens when you run out of time is... you go back to the beginning of the area. With a full time gauge, [[HaveANiceDeath no horrifying death animation]], or even a Game Over screen. Regardless, it's still one of the most disturbing scenes in the Kingdom Hearts series.
** There's something extremely unnerving about going through the worlds [[spoiler: in Castle Oblivion, with everyone--or at least their illusions--acting as though things are totally normal, not knowing that what they're seeing isn't real...]] The melancholy music doesn't help either, especially since it puts you in the frame of mind to imagine [[spoiler: all sorts of depressing interpretations of the alternate endings..]]
* ScrappyMechanic: "Play at night!" Hope you didn't begin during the daytime, and if you did, hope you have something else to kill time while you wait. Particularly annoying because you ''have'' to hit all the 50% multipliers on the floor if you want to get the best prize.
* TearJerker: Despite this being a relatively lighthearted game in the series, the moment Data-Sora discovered [[spoiler:Xion's existence and her fate]] is strangely poignant.
-->'''Sora''': W-wow, [[UnderStatement something terrible happened]], didn't it?
** [[spoiler: Data-Roxas]] is hands down miserable. [[spoiler: The poor kid not only has to deal with the non-existence of being a Nobody, he's a DATA CLONE of a Nobody. Understandably he doesn't take it very well, and seeing how just plain bitter he's become is heart-wrenching.]]
*** In addition, he keeps mocking Data-Sora about ''forgetting'' the people he met every time he leaves a room in Castle Oblivion. [[spoiler: Connect that with Xion's fate in ''358/2 Days'' and that certainly leaves a whole new layer to his bitterness.]]
* ThatOneBoss: [[spoiler:Sora's Heartless's third form]]. It'll [[{{Franchise/RatchetAndClank}} rip ya a new one]] in ten seconds if you're not careful.
* TheyChangedItNowItSucks: ''coded'' translates the new line in the Journal as the rather fancy "We must return to free them from their torment"; it was changed in ''Re:coded'' to the more straightforward "Their hurting will be mended when you return to end it"; another change is "Their torment has been lessened" to "There are more hurts than the one you have just undone". There are plenty of ways to argue as to which translation is "better".
* ToughActToFollow: As many reviews for the game have noted, following directly after ''Birth By Sleep'' doesn't do ''Re:Coded'' a lot of favors.
* WhatDoYouMeanItWasntMadeOnDrugs: Actually, Nomura ''was'' drunk when he made it. [[http://www.khinsider.com/features/Kingdom-Hearts-Trivia-38-3360 Seriously]].
