[[{{Kirby}} The pink puffball's]] second outing on the GameBoyAdvance, ''Kirby And The Amazing Mirror'' shifts from the standard linear platformer norm to a sprawling {{Metroidvania}} game with optional cooperative multiplayer.

The story begins with the Mirror World being taken over by Dark Mind, and Meta Knight going in to try and stop it. Meanwhile, as Kirby is walking he is attacked by a dark copy of Meta Knight from the Mirror World and split into four Kirbys of different colors. The four board a warp star and chase Dark Meta Knight into the Mirror World.

The game is essentially what you get if you throw the {{Metroidvania}} genre in a blender with ''VideoGame/TheLegendOfZeldaFourSwords'' and the ''{{Kirby}}'' franchise. The player must traverse a maze of nine interconnected areas, finding the maps for each, pressing buttons to connect them to the HubLevel, and defeating their bosses to collect the eight Mirror Shards to restore the [[TitleDrop Amazing Mirror]], the path to the FinalBoss. While you're doing that, the other three Kirbys are off on the adventure too, and you can call them by mobile phone at any time to help you fight enemies or solve puzzles which need an extra Kirby or two; the game also has a multiplayer mode which is pretty much the same thing except other players fill the roles of the other Kirbys.

''KirbyAndTheAmazingMirror'' is one of the ten GameBoyAdvance games to be available to participants in the Nintendo3DS Ambassador Program, released exclusively to 3DS early adopters for free on the [[=eShop=]] in December 2011. In April 2014, the game was brought to WiiU's Virtual Console. (Like all Virtual Console games in the US, the multiplayer mode is inaccessible in these releases.)
----
!!'''''VideoGame/KirbyAndTheAmazingMirror'' contains examples of:'''
* [[AllTheWorldsAreAStage All The Worlds Are A Battlefield]]: [[spoiler:The Dark Mind (first form) battlefields borrow from several levels, namely [[SpaceZone Candy Constellation]], [[TempleOfDoom Radish Ruins]], [[UndergroundLevel Cabbage Cavern]], and [[SlippySlideyIceWorld Peppermint Palace]].]]
* AlternateUniverse: The Mirror World.
* AmericanKirbyIsHardcore: Compare the [[http://upload.wikimedia.org/wikipedia/en/thumb/0/0b/Kirby_%26_the_Amazing_Mirror.jpg/250px-Kirby_%26_the_Amazing_Mirror.jpg American boxart]] to the Japanese version (see above).
** It is interesting to note exactly how the art changed. Closer inspection reveals that Kirby and Sword traded colors and swapped positions. Also of note is that the total Angry!Kirby to Jolly!Kirby ratio is maintained. Taking the multiplayer feature and Spray Paint item into account allows for some rather creative interpretations. All this considered, the American background is undoubtedly more menacing.
* BadassInDistress: Meta Knight goes off to stop Dark Mind, but as he enters the Amazing Mirror, Dark Meta Knight shatters the Mirror from the hub level side and seals Meta Knight in Dark Mind's dimension.
* BigBad: Dark Mind.
* BigDamnHeroes: This title turned the trope into a ''game mechanic'' - namely, the Kirbys never follow you, the only way to have them help you in both exploration and combat is to call them with your Kirby Phone. It becomes incredibly satisfying to call them for aid against bosses, with them literally coming out of nowhere... unless their ArtificialStupidity kicks in.
* BossRush: Unlockable after HundredPercentCompletion.
* CharacterNameAndTheNounPhrase
* DarkIsEvil: Dark Meta Knight and Dark Mind.
* DarkIsNotEvil: [[spoiler: Shadow Kirby]]
* {{Determinator}}: If you believe Kracko is the same entity in each game, then the fact that he chased Kirby ''into a parallel universe'' is what gives him this status.
* DualBoss: Master Hand and Crazy Hand.
* DuelBoss: Only the very final phase of Dark Mind, as in every other boss fight you can have the rest of the Kirbys backing you up.
** Granted, you ''can'' call the other Kirbys just before you deal the finishing blow to him in the fireball form battle, and then as many Warpstars appear as needed to chase down Dark Mind.
* EvilKnockoff: [[spoiler:Dark Meta Knight, a duplicate created by Dark Mind that masquerades as the true Meta Knight for most of the game.]]
* {{Expy}}[=/=]UndergroundMonkey: This is one of the few games that Whispy Woods didn't show up in, but King Golem fights almost identically.
** Wiz is one for Paint Roller and Dark Mind is one for both Nightmare and Zero. The only boss from a previous game to appear, besides Meta Knight [[spoiler:(in a sense)]], is Kracko.
* GoodAllAlong: [[spoiler:Shadow Kirby]]
* GottaCatchThemAll / OneHundredPercentCompletion: Collecting all of the treasures. You can tell when a room is fully completed when it glows on the map.
* HeartContainer: Four in the game; like level map treasure rooms and rooms that connect to the hub (distinguished from treasure rooms by marking that they go to Level 1 (which the hub level is technically part of) or another level's room connecting to the same place), their treasure rooms are larger than most rooms.
* InfinityMinusOneSword: The Smash ability; it's rare because the rare encounters with [[GiantHandsOfDoom Master Hand]], except for two where he's joined by Crazy Hand, or if you [[EasterEgg swallow two Noddys and let the selection stop itself]] are the only opportunities to obtain the ability until the copy ability room is unlocked (which requires all doors connecting to the hub or doors connecting to such rooms to be unlocked, thus this method is only available late in the game without SequenceBreaking) since no plain mooks grant it, but as the ''SuperSmashBros'' moveset for Kirby it mimics has moves taken from the Stone and Hammer abilities, it's useful for both breaking silver blocks requiring certain abilities (and unlike other moves, regardless of angle needed to break the blocks) and pounding in wooden stakes, though another ability would be needed to light fuses. That, and, it's [[RuleOfCool cool]].
* InfinityPlusOneSword: The Master ability, which can be used if Kirby has Meta Knight's Master Sword[[note]][[Franchise/TheLegendOfZelda not that one]][[/note]], is fittingly named because it can't typically be lost accidentally (when Kirby loses it, it doesn't disappear) and can get past any obstacle in the game, including any obstacle that requires specific abilities (silver blocks, wooden stakes, and fuses). It's also quite powerful and flexible, having far more attacks available than the plain Sword ability. However, the only time it can be used before the credits are seen at least once is during the final boss battle, so its main use is either for easy access to missed treasures or for [[RuleOfFun just screwing around post-game]] if the file has 100% completed.
* JackOfAllStats: The Smash and Master abilities are useful for getting around obstacles usually broken through with other abilities in addition to having a wide range of moves per ability. The Smash ability has the limitation that it can't light fuses, though the Master ability can.
* KingMook: King Golem
* LetsYouAndHimFight: Subverted with [[spoiler: Dark Meta Knight. The first time you fight him, he's masquerading as Meta Knight, and [[MythologyGag the fact that he doesn't]] [[DuelBoss throw you a sword]] [[ChekhovsGun is your first hint at his true identity.]]]]
* {{Metroidvania}}
* MinigameCredits: [[spoiler: The final shootdown against Dark Mind's eye form continues as the credits roll by, and a counter appears at the bottom of the screen to show you how many hits you've landed on him.]]
* MirrorUniverse: The Mirror World, [[CaptainObvious of course]], [[spoiler:or so it appears at first]].
* MythologyGag: The ending scene is nearly identical to the ending of [[VideoGame/KirbysAdventure Kirby's Adventure]].
* OddballInTheSeries: This is the only {{Kirby}} game to be a full {{Metroidvania}} instead of a straightforward PlatformGame the series' main games are known for (it's somewhat of a SpiritualSuccessor to ''The Great Cave Offensive'' from ''VideoGame/KirbySuperStar'' in that regard). It's also the ''only'' game in the entire series where [[AntiVillain King Dedede]] does not make an appearance, and Whispy Woods is absent as well[[note]]for the record, he appeared in ''Kirby: Squeak Squad'' on the file select screen.[[/note]], although King Golem is almost identical.
* OpeningTheSandbox: Hitting the large switch on the way to [[WarmupBoss King Golem]] unlocks a mirror linking the central hub to a location in Rainbow Route from where you can start freely exploring the rest of Mirror World. Before then, the game [[{{Railroading}} railroaded]] you through a small linear section of Rainbow Route and then through Moonlight Mansion before hitting said switch, although deviating is possible to a smaller degree if the player obtains and keeps a hold onto the Burning ability, such as being able to access Candy Constellation early from Moonlight Mansion.
* PaletteSwap: The three other Kirbys, as well as Dark Meta Knight and Shadow Kirby.
** Also, you can collect spray paint cans in treasure chests, which can be used on the main menu to change your Kirby's color, including a black-and-white one that looks somewhat like a higher-resolution version of how Kirby looked in the first game.
* RecycledInSpace: Technically ''Kirby's Adventure 2'', since ''Nightmare in Dream Land'' (originally ''[[KirbysAdventure Kirby's Adventure]]'') is the prequel to this.
* SequelDifficultySpike: One of the more difficult Kirby games for several reasons:
** You start with very low health (five bars).
** Enemy density is much higher than usual, and they are often placed in inconvenient spots, with a few ambushes thrown in. Many of them even attack much faster and more effectively than they do in previous installments.
** Many tight flying sections, with spikes or airborne enemies all around.
** You lose your ability after one hit from any attack.
* SequenceBreaking: It is possible to access the ability room, giving free access to almost every copy ability, before beating the first boss: after pressing the first large switch, Warp Star back to the hub and go hunting for the rest of them.
* SequentialBoss: Dark Mind has quite a few short phases in his first form, broken up by small levels; then a second form that's very similar to Zero; then an UnexpectedSHMUPLevel where you chase him to finish him off; then when you finally kill him you're allowed to keep pummeling him during the credits.
* ShoutOut: Master Hand appears as a miniboss in several places, and in combination with Crazy Hand is the boss of Candy Constellation. Additionally, one of Kirby's abilities in this game is the Smash ability, which gives Kirby his ''SuperSmashBros'' moveset (except for the standard special, which mimics his neutral-A), and is acquired by eating Master Hand.
** Dark Mind's first form is very similar to Nightmare, and its second form is a [[IncendiaryExponent fiery version of]] [[VideoGame/KirbysDreamLand3 Zero]].
* TechnologyMarchesOn: According to the history booklet in Kirby's Dream Collection, the inclusion of the cell phone mechanics were added because cell phones were new at the time.
* ThrowingYourSwordAlwaysWorks: Not directly, in this case--Meta Knight tosses his sword into the Dimension Mirror for Kirby to use against the final boss.
* UnexpectedSHMUPLevel: Dark Mind's final phase.
* VideogameSettings:
** GreenHillZone / HubLevel: Area 1, Rainbow Route
** BigBoosHaunt: Area 2, Moonlight Mansion
** UndergroundLevel: Area 3, Cabbage Cavern
** DeathMountain: Area 4, Mustard Moutain
** BigFancyCastle: Area 5, Carrot Castle
** UnderTheSea: Area 6, Olive Ocean
** SlippySlideyIceWorld: Area 7, Peppermint Palace
** RuinsForRuinsSake [=/=] TempleOfDoom: Area 8, Radish Ruins
** SpaceZone: Area 9, Candy Constellation
* WarmupBoss: King Golem fills this role as an {{Expy}} of Whispy Woods.
** King Golem is actually ''weaker'' than Whispy, since this was the first game since ''VideoGame/KirbySuperStar'' to use a draining meter instead of blips, he has roughly 25% health than Whispy usually does.
* WithFriendsLikeThese: Sometimes, summoning your Kirby friends can be a hindrance than a help.
