->''"Adventure is in the cards."''

''Kingdom Hearts: Chain of Memories'' is the second game in the ''Franchise/KingdomHearts'' series, and the only one on the UsefulNotes/GameBoyAdvance. Released in 2004, it's a sequel to ''VideoGame/KingdomHeartsI'' that bridges the gap between it and ''VideoGame/KingdomHeartsII''.

After the events of ''Kingdom Hearts I'', Sora, WesternAnimation/{{Donald|Duck}}, and WesternAnimation/{{Goofy}} are wandering the worlds in search of [[Disney/MickeyMouse King Mickey]] and Riku. Eventually they are led by a cloaked figure to a strange place called Castle Oblivion, where memories come to life within its walls as illusions. As they climb the floors and partially relive the events of their previous adventure, they learn about the strange girl known as Naminé from Sora's past and are antagonized by a strange group of people called the Organization (Organization XIII in later games). Though not everything is as it appears in the castle, as memories can be tricky things...

Rather than the usual ActionRPG style of combat, ''Chain of Memories'' uses a combination of action and "[[FightLikeACardPlayer card battling]]". The player must prepare a deck of cards to use in their battles, with those cards determining every action Sora takes sans movement. Cards can also be combined in "sleights" or special moves that tend to be very powerful, but come at the cost of using up cards completely for a fight.

''Chain of Memories'' was later remade as a UsefulNotes/PlayStation2 game (titled ''Re:Chain of Memories'') as part of the [[NoExportForYou Japan-only]] release of ''VideoGame/KingdomHeartsII: Final Mix+''. It was (much later) released as a standalone [=PS2=] game in North America. [[NoExportForYou Europe and Australia never got it]], but did get ''Kingdom Hearts HD I.5 Re[=MIX=]'', which contains ''Re:Chain of Memories'' remastered in HD. The remake replaces the 2D sprite art with 3D graphics, has voice-acted cutscenes instead of pure text with small voice clips, adds a new form for the FinalBoss, includes some new Attack Cards based off of Keyblades and Enemy Cards based off the Organization XIII members that appear in ''Kingdom Hearts II'', makes small tweaks to the battle system such as adding or removing some sleights, and completely removes the PlayerVersusPlayer mode. The ''HD I.5 Re[=MIX=]'' version is mostly identical to the the [=PS2=] remake, but has higher graphics resolution, UsefulNotes/PlayStation3 trophy support, and replaces the Attack Cards of the ''II'' Keyblades with some from ''VideoGame/KingdomHearts358DaysOver2''.

Has a LighterAndSofter [[Manga/KingdomHeartsChainOfMemories manga version]].
%%YMMV tropes are at YMMV/Kingdom Hearts: one page for all the games, as with the Moments.
!!This game contains examples of:
* AbsurdlyHighLevelCap: The average player will finish both Sora's Story and ''Reverse/Rebirth'' at around Level 30-40, give or take. Sora and Riku can both level up to Level 99.
* ActionCommands: The remake throws in the Reaction Commands featured in ''VideoGame/KingdomHeartsII'', which is used to extend the lengths or effects of various Sleights, and allows characters to access doors, save points, Moogle Shops and pick up crates and barrels.
* AlasPoorVillain:
** The Riku Replica.
** Vexen. Sora hated the guy for what (he thought) he did to Riku, and even he was horrified by the cruel way Axel dispatches him (while he's begging for mercy, no less!). Not helping matters is the fact that he was [[spoiler:trying to warn Sora about the trap he was walking into, shortly before Axel showed up]].
** Lexaeus.
---> "Forgive me, Zexion... This was a fight I should not have started."
** Zexion. Possibly the most brutal death of all the Organization members. Everyone else just died (some were more vicious than others; here's looking at you, Vexen). Zexion? He was strangled to ''death'', his life force ''slowly sucked out of his body'' as he lost consciousness. What makes this sad is that Zexion showed himself to be [[UndyingLoyalty highly devoted to the Organization's cause]], even up to his final moments, where he's absolutely ''mortified'' by the prospect of his death. That doesn't excuse his actions, mind you, but when you put him in comparison to the behind-the-scenes backstabbing game of hot potato that approximately half of the remaining members played, it's a bit depressing.
** Larxene, which doubles as a VillainousBreakdown.
--->[[SoreLoser "I'm... fading? No, this isn't the way I... I won't ALLOW...!"]] (Especially sad when delivered by Creator/YukoMiyamura.)
* AlphaBitch: Larxene, very much so.
* AnotherSideAnotherStory: Beating Sora's story unlocks the ''Reverse/Rebirth'' campaign, where you play as [[spoiler: Riku]].
* ArtifactMook: The Powerwilds and the Bouncywilds were Heartless originally meant for the Deep Jungle stage (based off of ''Disney/{{Tarzan}}''), but the world was axed due to legal issues and they were placed in Olympus Coliseum.
* ArtificialHuman: Vexen made one, [[spoiler:Riku Replica.]]
* ArtificialStupidity:
** Donald's Friend Card and associated Sleights have him cast two random spells from the Fire, Thunder, Blizzard, and/or Cure series, meaning he could potentially heal you twice when you're already at full health, ''not'' heal you when it would actually be useful, or even heal enemies by, for example, casting Blizzaga on an ice-elemental enemy.
** Hook is carrying the Pirate enemy card, which makes all of his cards 0s until he reloads. The problem is he has no idea how to use it -- in the right hands he would break everything you throw at him and then counter-attack, but he'll keep to his normal pattern. Just wait for him to make the first move and you'll break his 0s every time, leaving him with a very small deck to work with once he reloads, if he survives that long.
* AscendedExtra: Jiminy Cricket has a significantly bigger role in this game compared to others, appearing in almost all scenes.
* AssistCharacter: Party members like Donald and Goofy and Summons like Mushu from ''VideoGame/KingdomHeartsI'' have been turned into cards (Friend Cards and Summon Cards, respectively), which can be played to summon the associated character for one attack or used as part of Sleights.
** Donald uses Magic, which randomly casts 2 of Fire, Blizzard, Thunder, and Cure with the potential to double-cast one spell. Sleights involving him will power up his magic to the -ra or -aga tiers or will trigger {{Combination Attack}}s with Goofy and/or Sora.
** Goofy will either use Goofy Charge (original game) or do the Goofy Tornado (remake). Goofy Charge has him go up to an enemy and hit them with his shield, while Goofy Tornado has him do a SpinAttack to consecutively hit multiple enemies. Sleights involving him will increase his Goofy Charge's damage, increase the duration of the Tornado, or trigger {{Combination Attack}}s with Donald and/or Sora.
** Aladdin uses the Sandstorm attack on an enemy, swinging his sword to deal damage and produce Moogle Points for Sora to pick up. His Sleights increase the duration of the attack and the amount of Moogle Points dropped.
** Jack Skellington uses Surprise!, which randomly casts two of of Fire, Blizzard, Thunder, and Gravity with the potential to double-cast one spell. His Sleights power up his magic to -ra and -aga tiers.
** Cloud Strife attacks enemies with Cross Slash. His Sleights upgrade Cross Slash's power, or potentially Omnislash.
** Pluto (exclusive to the remake) uses Lucky Bounty to dig up used cards and HP Orbs. His Sleights increase the number of cards and HP Orbs found.
** King Mickey casts Pearl, which deals damage in a large radius, Stuns non-boss enemies, and heals the player. His Sleights improve his damage dealt and HP restored, or activate team attacks with Riku.
* AtTheCrossroads: There's a crossroads somewhere near Castle Oblivion. This is where Riku TakesAThirdOption regarding walking the path of light or the path of darkness.
* AwesomeButImpractical: Zig-Zagged. The Lexaeus card's Warp Break ability has a high chance of instantly eliminating enemies with a combo finisher. However, it doesn't work on bosses for obvious reasons.
** When you play as Riku, you actually get to use ''Dark Aura''. You remember ''{{that|OneAttack}}'' move as possibly having screwed the heck out of you on Sora's story (not to mention ''KH'', where it was one of the reasons Riku was ThatOneBoss in that game). Unfortunately, when playing as Riku, it tends to fall into this category - it's unavailable for a large percentage of the game because to use it you need to A) be in Dark Mode, and B) stock three 9-cards (the rarest and strongest cards) together, and you use a fixed deck. And if you can pull it off on bosses, you'll have to get them in ''just'' the right spot for them to not dodge it or break it. Still, though, it's ''very'' useful for clearing out trash mobs.
** Some sleights are that way, especially since the AI loves to cheat and break all of them. Jafar's card, however, can be used to prevent those sleights, such as Ars Arcanaum (which requires a value of 6 or less), from being broken by anything, even 0 cards.
** Some enemy cards have interesting effects, but they all cost a lot of CP. This is completely inverted for Riku though, as he can freely use any boss card he's earned, and even gets some normal enemy cards for free as part of his fixed decks.
* BadMoodAsAnExcuse: Larxene to Naminé when she begs her to leave off attacking Sora and company.
-->"I should tell you that I'm in an EXTREMELY foul mood. Thanks to you, all our plans are ruined!"
* BalanceBuff: The ''Re:Chain of Memories'' version increases the effects of leveling up Riku's Attack Points, making him stronger than the original.
* BatmanGambit: First off, there's the main one - Marluxia, Larxene, and Axel attempt to use Namine to rewrite Sora's memories so they can use him as a weapon against their Organization's leader, Xemnas. Eventually Vexen, another member the three are using to further this goal, feels left out one time too many and tries to reveal the plan to Sora. All along, however, Axel is actually a double agent as he's spying on the traitors for Xemnas and ends up sabotaging ''both'' Marluxia's plot and Vexen's ''own'' attempt to sabotage it, since Vexen was planning on telling Sora too much. Meanwhile, a group of Organization loyalists and associates of Vexen in the basement levels is trying to capture and use Riku due to their ''own'' suspicions about Marluxia's group. Axel sabotages ''them, too''. Later games add further facets to this: Xemnas sent the traitors to Castle Oblivion on purpose, and Axel was given a second mission to find Ven's body - and Axel only took on these missions to get on Xemnas's good side, because ''he'' and Saix were planning to betray Xemnas themselves eventually (which also belatedly provides a reason for Axel killing the basement group - to get rid of other members loyal to Xemnas).
** They're literally playing hopscotch with one another - and [[spoiler:judging by DDD, Axel and Saix came out on top! Even if one of them is half Xemnas and probably entirely mad...]]
* BattleHaltingDuel: The Card Duel mechanic in the remake's version of Reverse/Rebirth, which stops all action aside from the player and the enemy in question to perform the Card Duel.
* BerserkButton: "No, I'M me." is all it takes to send [[spoiler:the Riku Replica]] over the edge.
* BetaTestBaddie: The [[spoiler:Riku Replica]]. So much so that he wanted to [[spoiler:kill the original]] to have a sense of originality and self.
--> "As long as you're around, I'll never be anything other than a shadow!"
* BigBad: Marluxia in Sora's story, Ansem in ''Reverse/Rebirth''.
* BittersweetEnding: [[spoiler:Marluxia, Zexion, and Xehanort's Heartless are defeated, but Sora has to go into a coma until ''Kingdom Hearts II'' in order to regain his lost memories, Riku ends up WalkingTheEarth (albeit with ''King fricking Mickey'' helping him (well, at least for some time), and the Organization is still out there...]]
* BoringButPractical: Sleights can easily trivialize several bosses, especially Sonic Blade and/or Lethal Frame in the remake.
** Alternatively, sleights are largely unnecessary. It is entirely possible (and not too difficult) to simply pump your deck filled with 8's, 9's, and a couple of 0's. This allows you to essentially button mash until you need to heal or break an enemy sleight, and then rinse repeat.
** The Jafar Card (Attack Bracer). It allows you to use 20 cards in a row (taking away 3 if you use a sleight) without getting card broken. Meaning you can spam powerful low-cost sleights like Ars Arcanum without interruption and basically stun lock the enemy until the card effect runs out. This is one of the easiest ways to kill bosses. It was even stronger in the GBA version, where it was limited to 20 ''attacks'' instead of cards, and [[LoopholeAbuse sleights didn't count]].
** Mega Flare. Its the easiest way to grind Sora to max level.
** Exploiting the double-jump glitch with Riku, which allows him to dodge and then directly attack from the air afterwards multiple times. The only downside is that it can only be used in Dark Mode.
** Dark Firaga on Riku. It's just a Firaga that's blue... but it can ''really'' hurt some enemies, ''especially'' Lexaeus. Also, it might be better to trust on its accuracy than to bet on [[AwesomeButImpractical Dark Aura]].
** In the remake, abusing Card Duels against [[spoiler:Ansem, Seeker of Darkness]]. Winning Card Duels in Dark Mode makes for horribly overpowered Duel-specific Sleights, which can potentially drain all of his health in a matter of minutes.
** The Roxas Card in the remake. Double damage for 20 Attacks. Pair it with [[InfinityPlusOneSword Ultima Weapon]], and what more could you want?
** The Parasite Cage enemy card. It dispels the effects of the enemy card currently in use by your opponent. It may be expensive, but it does get rid of annoying effects such as Vexen's Auto-Life.
* BraggingRightsReward: Any cards you get during a new game [[spoiler: after completing Reverse/Rebirth mode once]] such as the Ultima Weapon and Ansem cards are these, because you've already beaten every challenge the game has to offer at that point.
** In the remake, the Gold Card and Platinum Card. The former sports the Premium Guard ability that lets you reload Premium Cards, and the latter makes you [[InvincibilityPowerUp invulnerable.]] You only get them for finishing the Card Collection and Jiminy's Journal respectively. [[RareRandomDrop Considering the drop rates for Enemy Cards...]]
* BroadStrokes: The plot of each Disney world is basically a very truncated retelling of its ''VideoGame/KingdomHeartsI'' plot, usually with references to memories thrown in.
* CallBack: The Xaldin Card in the remake gives Sora the original Aero spell from ''VideoGame/KingdomHeartsI''.
* CallForward: There is one level that comes from memories that gains new importance in ''Kingdom Hearts II'': Twilight Town.
** And in the remake, many of the cards gained after the game are KHII references.
* {{Catchphrase}}: After ''VideoGame/KingdomHeartsII'' introduced Axel's famous ''[[MemeticMutation "Got it memorized?"]]'', the original version of the quote that originated from the GBA game, ''"Commit it to memory"'', was {{retcon}}ned to ''"Got it memorized?"'' for the remake.
%%* TheChessmaster: Zexion. [[spoiler:He might have actually succeeded had it not been for Axel.]]
%%* CloningBlues: [[spoiler:Riku Replica]].
%%** And Vexen in the manga.
* ComicallyMissingThePoint: Goofy in Olympus Coliseum:
-->'''Phil:''' Two words: [[PunctuatedForEmphasis You! Ain't! Heroes!]]\\
'''Sora:''' You're wrong!\\
'''Goofy:''' Yeah, he said three words.
** This is repeated later in this same world, after Hades is defeated:
--->'''Sora:''' The games are canceled? How come?\\
'''Phil:''' Three words: everyone's pooped!\\
'''Goofy:''' Wait a minute, that was only two--\\
'''Sora:''' You gotta be kidding!
* TheComputerIsACheatingBastard: Enemy bosses have much easier requirements for their sleights than you do. This is somewhat justified since you have more techniques to choose from. [[spoiler:The exception to that would be Riku-Replica, since you can actually use the same sleights as him on a Reverse/Rebirth playthrough and see that the numbers are different]].
* CrypticConversation: Just about everything the Organization members say to Sora until late in the game is very cryptic and they avoid actually answering his questions, particularly those about Riku and King Mickey. Justified, [[spoiler:as they're simply trying to get Sora to stay in Castle Oblivion as long as possible so they can brainwash him.]] When Sora finally finds out what's going on, the remaining members drop this.
* DarkerAndEdgier: Compared to the first game. Sure, you're not saving the universe full of beloved Disney characters from being destroyed by the legions of hell this time, but ''Chain of Memories''[='=] continuously oppressive tone and seeing [[TheHero Sora]] becoming more and more of a jerkass as the game progresses is pretty dark when held up next to the optimistic and adventurous tone of most of the first game.
** You're up against a much higher concentration of humanoid antagonists this time around. A good half of the boss fights are man-to-man death battles, rather than the constant bombardment of Heartless, monstrous-looking (or monster-transforming) Disney villains, or fights just meant to test your skill, such as Coliseum duels. These antagonists also receive a little bit more screen time than the first game's. [[spoiler:Riku's tragedy and identity crisis is also given more focus here than in the first game.]]
* DeathIsASlapOnTheWrist: Dying places Sora/Riku in the room before the one where the player died, without any real penalty.
* DeclarationOfProtection: Sora and Riku [[spoiler:Replica]] towards Naminé. Even when they both discover [[spoiler:their memories of her are fake and that Riku is a replica of the real Riku and created by Vexen]], they still resolve to protect her.
-->'''Riku [[spoiler:Replica]]:''' "What can you possibly think I ever had? [[spoiler:Both my body and my heart are fake]]. But there is one memory I'll keep, [[spoiler:even if it's just a lie]]. Whether it was a [[spoiler:phantom promise]] or not, I will protect Naminé!"
* DiscOneNuke: The Maleficent Enemy Card (increases damage for the next 30 attacks at the cost of deck reload speed) is obtained extremely early in ''Reverse/Rebirth'', as Maleficent is the first boss of that mode. Since ''Reverse/Rebirth'' doesn't have the card reload speed mechanic and all Enemy Cards are permanently part of your deck after being obtained, the Maleficent card can be used from the get-go without any real penalty.
** For Sora players, Simba. Simba is very useful in the game boy advance version because he hits everyone "in front of" him (which, in the game boy advance's view, is basically "In the direction he's facing"). Thus with good positioning you'll have an attack that can't miss and can knock enemies around. By the time you fight Larxene the first time, you'll have to put him in a sleight for him to hold up though.
* DistressedDamsel: Naminé. Half of this distress is real, while half of it [[spoiler: is bait for Marluxia's trap for Sora.]]
* TheDragon: Larxene to [[BigBad Marluxia]], and [[TheBrute Lexaeus]] to [[TheDarkChick Zexion]].
* DreamworksFace: Donald and Goofy sure look smug about something.
* DullSurprise: Marluxia's voice actor in ''Re: Chain of Memories''. Possibly justified, because he ''is'' a Nobody...
* DummiedOut: The Jungle King card is in the game but cannot be obtained outside of hacking.
* EarlyBirdCameo: In America, ''Chain of Memories'' was the first game to show off the ''Final Mix''-exclusive Keyblades before ''Kingdom Hearts Final Mix'' made it overseas.
* EndgamePlus: In Sora's story in the remake, after clearing the game and saving your data, you get dumped back into the room right before the final boss. You can then backtrack to the other worlds and revisit the Treasure Room cards to collect new Enemy Cards based on the Organization XIII members that appear in ''VideoGame/KingdomHeartsII'', new Attack Cards based on ''Kingdom Hearts II'' and ''[[UpdatedRerelease Kingdom Hearts Final Mix]]'' Keyblades in addition to the [[InfinityPlusOneSword Infinity Plus One Attack Card]], and the [[NotQuiteFlight Superglide]] ability.
* EnemyCivilWar: [[spoiler:Marluxia and Larxene are trying to take over the Organization by manipulating Sora (via Naminé) to do their bidding. Zexion, Vexen, and Lexaeus suspect their treachery and are trying to figure out what exactly they're up to and stop them. Axel is a wild card who seemingly flips through allegiances between the two groups, but is revealed in ''358/2 Days'' to have been sent by Saïx to kill them all for personal gain.]]
* ExplodingBarrels: The Barrel Spider, a type of Heartless ChestMonster that likes to [[ActionBomb explode in your face]] during battle.
* EvilCannotComprehendGood: Even though it's part of their plan, the Organization members seem genuinely confused as to why Sora would strive so hard to protect Naminé even though [[spoiler: his memories of her are fake.]] [[JustifiedTrope Justified]], since they have no hearts and therefore have only a theoretical understanding of emotions. [[spoiler: [[VideoGame/KingdomHearts3DDreamDropDistance The latter turns out not entirely true though.]] ]]
* FakeMemories: As Sora climbs the castle, Naminé injects him with false memories of his past. He forgets about Kairi and thinks that Namine is the one he's supposed to be protecting.
* FightingAShadow: The first fight against Marluxia is against an illusion of him.
* {{Foreshadowing}}: After Riku first meets [=DiZ=], if you talk to Mickey, he will tell him that he feels like he's met him before. Come ''Kingdom Hearts II'', we learn that [[spoiler: Mickey definitely met him back when he still went by Ansem the Wise]].
* ForgottenFriendNewFoe: Naminé. [[spoiler:[[FakeMemories Or is she?]]]]
* FightLikeACardPlayer
* FireIceLightning: While you slowly obtain them, three of the six villains have an element each [[spoiler:at least until Axel kills Vexen.]]
* GambitPileup: Let's see... First off, there's the main one--Marluxia, Larxene, and Axel [[spoiler:attempt to use Namine to rewrite Sora's memories so they can use him as a weapon against their Organization's leader, Xemnas]]. Eventually [[spoiler:Vexen, another member the three are using to further this goal, feels left out one time too many and tries to reveal the plan to Sora]]. All along, however, [[spoiler:Axel is actually a double agent--he's spying on the traitors for Xemnas and ends up sabotaging both Marluxia's plot ''and'' Vexen's ''own'' attempt to sabotage it, since Vexen was planning on telling Sora ''too'' much]]. Meanwhile, [[spoiler:a group of Organization loyalists and associates of Vexen in the basement levels is trying to capture and use Riku due to their own suspicions about Marluxia's group]]. [[spoiler:Axel sabotages ''them'', too]]. Later games add ''further'' facets to this: [[spoiler:the Superior sent the traitors to Castle Oblivion on purpose, and Axel was given a second mission to find Ven's body--and Axel only took on these missions to get on Xemnas's good side, because ''he'' and Saix were planning to betray Xemnas themselves eventually (which also belatedly provides a reason for Axel killing the basement group--to get rid of other members loyal to Xemnas)]].
* {{Glamour}}: Naminé's power to insert herself as a trusted friend of Sora's.
* GlamourFailure: The screen will flicker when [[spoiler:artificially created memories start failing]].
* GlassCannon: Riku has no reliable source of healing, just a few enemy cards and the Mickey Friend Card, and his reliance on Sleights in Dark Mode makes him liable to wear his deck out fast. However, he can quickly rack up a lot of damage and his Dark Mode attacks are devestating.
%%* GratuitousItalian: The titles of a few pieces on the soundtrack.
* GreaterScopeVillain: [[spoiler:The leader of the Organization (i.e. Xemnas), who serves as the BigBad in the next game. If you played ''KH: Final Mix''/''I.5 HD Remix'', you can encounter him as [[BonusBoss the Unknown]].]]
* HisNameIs: [[spoiler:Vexen is killed by Axel just before he can tell Sora that Marluxia is manipulating his memories and reveal the existence of Roxas.]]
* HoldingBackThePhlebotinum: [[spoiler:As Jiminy Cricket chronicles all of his adventures with Sora, the plot of the game could easily be solved simply by having Jiminy read his journal to Sora and his friends. The game solves that problem by making it affected by Castle Oblivion's memory-erasing magic as well. In other words, the Castle itself blanks the pages of Jiminy's Journal so that it doesn't break the plot.]]
* HolyHandGrenade:
** Trinity Limit creates a glowing golden magic circle on the floor, after which beams of holy light rise from it. It is bar-none the single-strongest AreaOfEffect Sleight in the game. [[BadassBoast "It's over!", indeed.]]
** The magic sleight Holy, which creates pillars of light to attack foes. Notable in that it is the only sleight that requires three Item cards, so in a way, it is similar to a grenade in utility.
* HotBlooded: Riku [[spoiler:Replica]] is overly passionate about protecting Namine, challenging Sora to fights over Sora not remembering her.
* HumanoidAbomination: [[spoiler:Naminé and the Organization, though their nature isn't fully revealed until [[VideoGame/KingdomHeartsII the next game.]] ]] Also, [[spoiler: Riku Replica]].
* IKnowYoureInThereSomewhereFight: Sora at one point fighting Riku. The catch? [[spoiler:It's not really Riku at all, but a clone created by Vexen, and the memories they're fighting over are fake too.]]
-->'''Riku:''' I remembered it, Sora. I now know the one thing that is most important to me. Protecting Naminé. Nothing else matters---not a thing.\\
'''Sora:''' Hey... Riku... I think I'll jog your memory.
* InterfaceScrew:
** In the original Game Boy Advance version, Lexaeus knocks the screen down so you fall towards him - Don't ask how he doesn't destroy Castle Oblivion, considering he's doing this in the ''basement''.
** Marluxia's third form in the remake has an attack that ejects all the cards from your deck and scatters them around the arena, rendering you completely powerless until you can pick a few up.
* ItOnlyWorksOnce: Premium Cards. You can identify them by their shiny coat and gold number. They cost much less CP to add to your Deck, but if you use it in battle for any reason, it's gone for the rest of the fight. The only way to skirt around this is with the remake-exclusive Gold Card, but by the time you get this thing, [[BraggingRightsReward you won't have much else to do anyways.]]
* {{Jerkass}}: Most of the villains, but particularly Larxene and Vexen. No wonder they get on each others' nerves...
** Sora also becomes one, albeit for a little one. He gets mad at Donald and Goofy out of spite and temporarily abandons them. When Jiminy calls him out on it, he tells him to shut up. However, ThePowerOfFriendship reunited the heroes.
* KarmaHoudini: [[spoiler:Axel. Don't worry, it'll all catch up to him in ''KHII'', though it's [[AlasPoorVillain actually pretty sad]] when it happens.]]
%%* LetsGetDangerous:
%%-->'''Axel:''' "Remember the order: 'You must eliminate the traitor.' I always follow orders, Marluxia."
* LevelGrinding: Both Sora and Riku max at Level 99. Thing is, both the main story and ''Reverse/Rebirth'' are beatable at about half there for anyone reasonably skilled with the card system. So if you're someone that likes to max out levels, get ready for lots of level grinding, pointless for anything other than just getting the levels, since there are no [[BonusBoss bonus bosses]] to fight. Not only that, but there are no really quick leveling strategies such as the tech points that the original game has, and eventually the bonuses you get for leveling up stop having any practical effect in speeding up battle completion. (Riku's attack points max at 30 and Sora doesn't even get attack points.) ''HD I.5 [=ReMIX=]'' ups the pain by linking Trophies to max levels for both Sora and Riku.
* LifeDrain: The Neoshadow card's Bio effect (based on the ''Franchise/FinalFantasy'' spell of the same name) causes enemies to slowly lose HP until Sora reloads his deck.
* LipLock: Hits the remake '''hard'''--in English, anyway. The cutscenes look fine in Japanese, but despite using the same assets as the game's in-engine graphics, all the cutscenes are actually pre-rendered video files. Instead of re-rendering new videos for the English dialogue, the scenes were simply dubbed to English as-is, leading to oddly-paced line readings, SesquipedalianLoquaciousness for the sake of a few extra syllables, and of course, the lip movements simply not matching the words being said. This all only grinds more because the cutscenes otherwise look just like ''[=KH1=]'' and ''2''[='s=] cutscenes, which ''were'' rendered in-engine and as such ''were'' altered to match the English dialogue.
* LivingMemory: The majority of the characters in Castle Oblivion that Sora and co. encounter are very powerful illusions created by the castle using his memories.
* LovableTraitor: Axel.
* MacrossMissileMassacre: Dark Riku's Dark Barrage Sleight in the remake, which fires a payload of Soul Eaters at a target.
* MadScientist: Vexen, the Chilly Academic.
* MagicMisfire: The Blazing Donald sleight, only in the original, is caused by Donald screwing up a Fire spell. He then runs around the screen while on fire.
* MediumAwareness: The during the first part of Traverse Town, Goofy and Donald had effectively disappeared, forcing Sora to summon them to battle using cards through the in-game tutorial in order to see them again. A few scenes later, they literally reappear right besides Sora alongside a change from their classic outfits into the ones they wore during the first game, much to their confusion. Even they don't know why the castle's doing that to them. It's this trope as for the rest of the game, it's implied they kept following Sora even though they don't seem to be present on the overworld screen.
* MindScrew: The scene in Destiny Islands when Sora talks to the two Naminés. Just look at this beauty of a line:
-->'''Second Naminé''': "No, Sora! Don't listen to me!"
** Also counts as {{Foreshadowing}}, given that [[spoiler: one of the Naminés transforms into Kairi.]]
* MinigameZone: In the remake, The 100-Acre Wood gets promoted to this, complete with a new set of minigames.
* MirrorMatch: [[spoiler: For obvious reasons, the first fight against Riku Replica is this if you're playing as Riku, especially when you managed to enable Dark Mode during the fight. He even uses the same techs, although the requirements for them differ from the real Riku (of which you're playing as). Averted with the second fight where he undergoes Divergent Character Evolution in his fighting style. As the result, not only does he look slightly different (he gains a shield), he also uses a different set of attacks.]]
* MookChivalry: Since the battle system is reminiscent of TabletopGame/{{War}} and beating opposing cards by having higher values, only one foe can play an attack card at a time.
* MrFanservice: The Organization members and Riku [[spoiler:Replica]]. The manga even portrays the latter as a [[TheWoobie Woobie]] in the epilogue, even if it's PlayedForLaughs.
* MyRulesAreNotYourRules
** Like Sora, the Organization members, as well as other bosses with set decks, have a limited number of cards in their decks, and when they run out they have to reload. This makes it a perfectly viable strategy to focus on breaking their cards instead of depleting their HP. Of course, many of them carry Hi-Potions and Mega-Ethers so even broken cards can be reloaded, but then, Sora can do that too. The one advantage they have is the ability to reload their decks while moving.
** [[spoiler: Inverted in a few ways with Riku. Unlike Sora, Riku's reload card doesn't have a count, and you only need to hit the button to reload instantly every time. Bosses with decks of their own are still limited by their reload-counter. This might be compensate for the fact that Riku's decks are pre-set.]]
* NoPronunciationGuide: English-speaking players of the text-only GBA version were very surprised upon playing the fully-voiced remake to learn that Marluxia was actually pronounced "Mar-loo-sha".
* NoSell: [[VideoGame/KingdomHeartsII Luxord]]'s Omni Break in the remake, which lets Sora Card Break any 15 Attacks and/or Sleights regardless of whatever card he throws out.
** The Xemnas card's Quick Barrier allows Sora to outright ignore damage from a combo beyond the first hit.
* NonDubbedGrunts: The Organization members in the [=GBA=] version.
* NostalgiaFilter: Discussed in-universe. Dr. Finklestein is making a potion that will show someone their "True Memories." He comments how the heart, specifically, emotions, can distort memories. [[spoiler:Later on, Oogie Boogie tries the potion, and is driven insane by it. Jiminy Cricket muses that "True Memories" could be rather dangerous.]]
* NotQuiteDead: [[spoiler:Part of Ansem, Seeker of Darkness survives in Riku's heart, though he lacks a physical form.]]
* OddballInTheSeries: The only installment to use a card battle system. However, because these gameplay changes [[JustifiedTrope are integral to the game's story]][[note]]the cards are fragments of Sora's and his friends' memories[[/note]], this instance fares better than other examples.
* OldSaveBonus: In the Japanese version of ''Re:Chain of Memories'' the second Room of Rewards items, which feature characters and Keyblades from ''VideoGame/KingdomHeartsII'', can only be obtained if you have a completed ''II Final Mix'' save file. For [[NoExportForYou obvious reasons]] the English release drops this and simply requires clearing both stories. The ''I.5 [=ReMIX=]'' version changes the condition to having completed ''358/2 Days'', and the obtainable attack cards to Keyblades used by Roxas in that game.
* OminousPipeOrgan: [[http://youtu.be/yehRjq03VU4 "Struggle Away"]], [[http://youtu.be/t8F8x6kQpZI "The Force in You"]], [[http://youtu.be/6OCTzNpwjsw "Revenge of Chaos"]], [[http://youtu.be/CZbkdc5xePI "Castle Oblivion"]], [[http://youtu.be/inAz55ybcyA "Forgotten Challenge"]], [[http://youtu.be/z_V3So7hRVY "Graceful Assassin"]], and [[http://youtu.be/pQx9NBUqn0k "Scythe of Petals"]].
* OneHitKill:
** Marluxia's final form in the remake can use a Sleight called Doom, which, on contact, entraps Sora and plays a cinematic with a countdown above Sora's head and six of Marluxia's cards at the bottom of the screen. If the player is unable to break all of Marluxia's cards before the countdown expires, Sora dies instantly, no exceptions.
** The Lexaeus Enemy Card grants the effect Warp Break, which gives you a very high chance of instantly banishing an enemy from existence if you strike them with your combo finisher. However, you can't get drops such as MP and EXP from killing an enemy this way, so it's not very useful for grinding.
* OneStatToRuleThemAll:
** For Sora, it's Card Points (CP). With more CP, more cards can be added into Sora's deck. Sleights, the main source of Sora's best attacks, become more plentiful as well.
** For Riku, it's Attack Points (AP), since unlike Sora he can't raise his damage through better attack cards and new sleights.
* PetalPower: Marluxia.
* PlotHole: Twilight Town is treating as anomalous because Sora has never been there, and therefore has no memories of the place for the Twilight Town world card to draw from. While this is true, this seemingly ignores the fact that ''every'' time the party enters a new floor, they act as if they've never been to that world.
* PowerParasite: Zexion's gimmick in the remake. Whenever he attacks Riku, the player loses a card from their Deck and it goes to Zexion. Once Zexion has amassed a large enough collection, he'll summon duplicates of himself, each wielding Riku's Soul Eater, and use your Attack Cards against you.
* PrecisionFStrike: Axel gives a Disney-level one in the GBA version which fully cemented him as awesome in the eyes of the fans.
-->'''Axel:''' "Now, Sora! Naminé! Riku! Marluxia! Larxene! It's about time you gave me one '''hell''' of a show!"
* ThePromise: Most of Sora's story is based on the promise that he and Riku both supposedly made to Naminé on a shooting star to protect her. [[spoiler: But the promise is fake and so is Riku: Naminé herself implanted the promise both of their memories and the Riku is actually a replica of the real Riku. Even after they both know the truth, though, they still vow to protect her.]]
* PsychoElectro: Larxene. One of the most out and out CRUEL people in the series. Even Maleficent comes across as more sympathetic [[VideoGame/KingdomHeartsII in the next game]], and she's the freaking "Mistress of all evil!"
* PunBasedTitle: Reverse/Rebirth. Transliterated into Japanese, ''both'' words would be "''ribāsu''".
* RandomizedDamageAttack: Sorta. The Sea Neon's Random Values ability [[ExactlyWhatItSaysOnTheTin randomizes the values of the cards you play.]]
* RecurringBoss: The Riku Replica is fought 6 times over the course of the two story modes: 4 times for Sora and twice for Riku.
** Gets [[LampshadedTrope lampshaded]] after Sora gets through Floor 9 as Goofy and Donald look around, wondering where Riku is and assuming in the end that he got tired of fighting Sora.
* RememberTheNewGuy: As Sora climbs the castle, he talks about how previously unmentioned Naminé used to live at Destiny Islands as part of his friend group before moving away. [[spoiler:Subverted. They've never met before, Sora just thinks they know each other because of Naminé's ability to alter memories.]]
* SchizophrenicDifficulty: Reverse/Rebirth as the game features fixed decks. As a result? Some levels wind up ''much'' harder because you're stuck with a crappy deck. Wonderland in particular only gives you ''9 attack cards'', without a single one being above the number 5.
* SecretAIMoves: In the remake, [[spoiler:Ansem, Seeker of Darkness's]] Sleightbind, which hides his stocked Cards and Sleights until he uses them. As the result of the lack of a multiplayer feature, the boss's Enemy Card gets a new effect for Sora in his EndgamePlus that reduces elemental damage, but when the boss uses it in Reverse/Rebirth, it still has its original effect.
* SesquipedalianLoquaciousness: Marluxia likes to use more complex words when it's not necessary.
-->'''Axel:''' "You give a challenge like that to Vexen, and he'll... ''seriously'' want to eliminate Sora."\\
'''Marluxia:''' "That would be an unfortunate denouement."[[labelnote:Translation]]That'd be a bad outcome.[[/labelnote]]
%%* SmugSnake: Vexen and Zexion.
* SoreLoser: Larxene, after Sora defeats her for the second and final time.
* TheStarscream: [[spoiler:Marluxia is this in regards to Xemnas.]]
* SpellMyNameWithAnS: In an inverted case of JapaneseRanguage gone wrong, the Sleight "Lethal Frame" was accidentally mistranslated as "Lethal F'''l'''ame" in the original [=PS2=] release of the remake. The ''HD I.5 [=ReMIX=]'' release fixed it.
* ATasteOfPower: An incredibly odd example in that it happens about 3/4ths of the way through Reverse/Rebirth, and only in the remake. During the remake-exclusive boss fight against Zexion, Riku gets a massive boon in the way of ''being able to stay in Dark Mode for the entire fight.''
* TheStationsOfTheCanon: That Sora (re)experiences all of the events of the first Kingdom Hearts game (except for a certain Important Promise) is a major plot point, since he is literally re-visiting his memories (while [[spoiler: Naminé manipulates them]]).
* SuperMode: Once Riku gets 30 Dark Points (obtained by taking damage or breaking enemy cards), he will enter Dark Mode. Dark Mode gives Riku increased speed and power, plus it lets him use sleights without requiring the Mickey Friend Card.
* {{Tagline}}:
** "Adventure is in the cards." - ''Chain of Memories''
** "Memory is the key." - ''Re:Chain of Memories''
* ThrowingYourSwordAlwaysWorks: The four Raid sleights, where Sora throws the Keyblade... and it returns. {{Jusitified|Trope}} due to the Keyblade having a SummonToHand power.
** In the remake, Riku's Barrage Sleight.
* TitleDrop: Several times. It is explained that memories are connected, 'like links of a chain'. Thus, anyone who feels like screwing with Sora tends to lash out with one of these. Though, in the end, it's Naminé who has the last word.
-->'''Vexen:''' "If you remain bound by the ''chain of memories'' and refuse to believe what is truly found inside your heart, then throw it away."
-->'''Marluxia:''' "Imbeciles...You would knowingly shackle your heart with a ''chain of memories'' born of lies?!"
--> '''Naminé''': "You'll forget me, but that's just the links of the chain of memories coming undone... I want to believe, that our chain of memories will be connected again someday..."
* TookALevelInJerkass: [[spoiler:As Sora's heart is manipulated by Naminé, he ''definitely'' becomes more Jerkass compared to his original self. When Donald and Goofy show some concern for him as they approach the twelfth floor, Sora accuses them of wanting to give up and ditches them, doing the twelfth floor alone. When Jiminy Cricket calls Sora out for his behavior, Sora yells at him to shut up.]]
** [[spoiler:He's slightly better in the manga adaptation, and explains to Jiminy on why he abandoned them as opposed to telling him to shut up]].
* TrickBoss: [[spoiler:Marluxia's third form in ''Re:Chain of Memories''.]]
* TheUnfought: Despite being the secondary antagonist of ''Reverse/Rebirth'', Zexion is never fought; he's finished off in a cutscene. {{Averted|Trope}} in the UsefulNotes/PlayStation2 remake, where he's fought after attempting to corrupt Riku at Destiny Islands.
* UnwittingPawn: Sora spends thirteen floors walking straight into the Organization's trap.
* UseYourHead: Using Goofy as a battering ram in a sleight exclusively for the [=PS2=] version.
* UselessUsefulSpell: Zantetsuken. You would think the single strongest finishing move in the series would be as equally devastating in this game, right? Not exactly. It requires three 9 Cards or three 0 Cards to perform, neither of which are cheap to add to any deck (using all 9s does make it nigh-impossible to break though). Its effect does absolutely worthless damage and, if used to break a card, prevents that card from being used for the rest of the battle. It has its uses in boss fights, but outside of that there is no reason to use the Sleight ever.
* TheVeryDefinitelyFinalDungeon: Castle Oblivion's thirteenth floor. All the previous levels have been changed to appear as one of the worlds from Sora's memory. For the final level, all the illusions have been stripped away, and it is simply... Castle Oblivion.
* VillainousBreakdown: [[spoiler:Zexion]].
** Also, Larxene after Sora defeats her once and for all, causing her to fade away (see both AlasPoorVillain and SoreLoser above).
* VocalDissonance: The remake uses full voice acting for most cinematics, which results in Sora having his ''VideoGame/KingdomHeartsII'' voice for much of the game. However, if you pay close attention, some of his voice clips for certain moves were ripped straight out of ''VideoGame/KingdomHeartsI'', creating a slightly jarring difference.
* VoiceGrunting: The [=GBA=] version features this in battles only. The trope is applied more literally in the English version, where all voice clips containing actual words by newly introduced characters like the Organization were cut (seeing as they were in Japanese, which would jar badly with the English-speaking recurrers, of course) and only the grunts, laughs, etc. were left in. Undone in the remake, which features full sets of voice clips for everyone in both languages.
* WhamEpisode
** The first appearance of Twilight Town, which by this point in the series is unfamiliar to both the player[[note]]LateArrivalSpoiler notwithstanding[[/note]] and Sora. This is also when important revelations begin happening.
** Destiny Islands in Reverse/Rebirth. [[spoiler: It's where it's revealed to Riku that it was ''him'', not Ansem that opened the door back at Destiny Islands, causing it to be lost to darkness.]]
