* SugarWiki/AwesomeMusic: The whole. Damn. Soundtrack. Check it out [[AwesomeMusic/{{Kirby}} here]].
* DracoInLeatherPants:
** We have [[spoiler:Galacta Knight]], who was [[spoiler:so powerful and dangerous that he had to be sealed away]]. Sounds like some horrible villainous character, right? Exactly! That is why every other fangirl draws him as an overly-cutesy, baby-faced sweetie that loves to tickle Meta Knight. There's also the popular fan theory that [[spoiler:he's a grown-up version of Kirby]], so in that case it might be justified...
** And, of course, there's [[spoiler:Marx]]. Okay, so he did [[spoiler:incite conflict between the sun and moon just to trick Kirby into summoning NOVA, granting him the power to rule Pop Star and do whatever he pleases]], but...but he's so ''cute!'' There have been a number of fanfics either attempting to redeem him or altogether ignoring that he was evil in the first place. He's also often shown being buddies with [[spoiler:Magolor]], a similar character from ''VideoGame/KirbysReturnToDreamLand''.
* EnsembleDarkhorse:
** [[spoiler:Galacta Knight]] immediately gained a huge fanbase after ''Ultra'' was released.
** [[spoiler:Marx]] is generally agreed to be the most popular villain in the series after [[spoiler:Zero Two and Magolor]].
** Among regular bosses, Heavy Lobster proved popular enough to get his own theme in the remake, appear in the [[Anime/KirbyRightBackAtYa anime]], and appear as a boss in the Kirby Brawlball subgame in ''Kirby Mass Attack''.
** This was the game that introduced Bandana Dee, whose popularity became significant enough fast enough that he had several cameos before being PromotedToPlayable.
* FridgeBrilliance: Meta Knight telling Kirby "prepare to die" was changed to "come to meet your doom" in ''Ultra''. This appears to be [[{{Bowdlerise}} Bowlderization]] on the premise of NeverSayDie at first, but maybe he's saying it because he's only an AntiVillain and doesn't want Kirby to truly die?
* GameBreaker:
** Stone Kirby in ''Ultra'' completely annihilates the otherwise NintendoHard True Arena if you're willing to fight cheaply and spend a lot of time in rock form to keep from being hurt.
** The Plasma and Hammer Ability can count as this as well. Plasma by virtue of being the only power with a projectile that goes across the whole screen (provided you've done at least a little charging), and Hammer because it's just so damn powerful.
** Hammer's greatest strength is unlocked for Kirby in Milky Way Wishes; when using the Hammer Throw technique, Kirby sacrifices his Hammer ability ForMassiveDamage, but because of how abilities work in MWW, you can just re-equip Hammer and do it again almost immediately.
** In Milky Way Wishes, the Copy ability, which is ordinarily pointless for Kirby to have, becomes this by allowing Kirby to bypass the gimmick of Milky Way Wishes and get his ability to copy back. Consequently, the Copy ability is very well hidden. TAC, the ability's Helper, is similarly helpful. His attack is lightning fast, does surprisingly high damage, and his guard makes him completely unhittable. Also, he fully heals when copying an ability.
** Jet is by far the best ability in the game for [[SpeedRun speedrunning.]] Kirby moves extremely fast with the ability and can even [[SkippableBoss bypass some minibosses]] due to how high the Jet can fly, causing it to completely fly over the usual area that would trigger the miniboss battle. Its only weakness is that it isn't very effective against bosses compared to, say, Plasma or Hammer.
** Any ability that offers a flexible throw attack, such as Fighter, Suplex, Yo-yo, etc. This is mainly since if you can get your hands on any object/enemy the boss or enemy throws out, you can toss it right into them ForMassiveDamage.
* HellIsThatNoise:
** Combining this with MostAnnoyingSound gives you the final phase of ''"Revenge Of Meta Knight"''. Those sirens...
** [[spoiler:Marx Soul's death cry, which is a mixture of agony, sorrow, and insanity, all to make a ''loud'' cacophony.]]
* HilariousInHindsight: One of the levels in Dyna Blade is called [[WebAnimation/CharlieTheUnicorn Candy Mountain.]]
* HoYay: Kirby and his helper seem to "kiss" when one of them grabs a food item and then touches the other party. Most of the possible helpers are ''male''. Guess what's implied? And yes, the tie-in manga [[LampshadeHanging acknowledged this]].
* ItWasHisSled: [[spoiler:Marx as a villain was doomed to be spread to many. Galacta Knight, even more so]].
* LastLousyPoint: The ''Ultra'' remake is ''technically'' 100% finished without doing this, but if you actually want to get everything in the game (meaning video 00 in the Theater), you have to beat Helper to Hero using all twenty helpers. Not only is that incredibly tedious, but a select few of them ''really'' don't make it easy.
* MagnificentBastard: [[spoiler:Marx, who tricks the Sun and the Moon into fighting, manipulates Kirby into summoning the Galactic Nova, then steals his wish to gain enough power to become the ruler of Planet Popstar]].
* MagnumOpus: Still to this day, many fans consider this and ''VideoGame/KirbysAdventure'' the finest games in the series.
* MemeticBadass: [[ZeroEffortBoss Waddle Dee]], [[BlatantLies destroyer of worlds.]]
* MostAnnoyingSound: [[spoiler:The cry of Marx Soul when you ''finally'' defeat him.]]
* NightmareFuel:
** [[spoiler:Marx Soul's death cry. Dear ''gods.'']] Even scarier when you consider this: [[spoiler:that scream emulates his rage at losing again to Kirby after who knows ''how'' long of burning in the pit, his fear of death, his pain as he dies.]] Definitely NightmareFuel.
** The cutscene preceding [[spoiler:the Marx Soul battle]] can be pretty chilling as well, seeing as it shows [[spoiler:''Marx's corpse'' drifting through space, eyes staring blankly and skin drained of color. Then he's engulfed in darkness and transformed into a monstrous revenant]]. ''Brr.''
** Some found Wham Bam Rock (especially his original design) sort of creepy looking. His new design looks like a floating mask, his old design looked like a bunch of organic facial features floating in the dark.
* ScrappyMechanic: You can't get rid of your ability by simply pressing Select like in all other ''Kirby'' games. You have to create a Helper and un-create that Helper to do so, which gets tedious after a while. The ''Ultra'' remake restores the ability.
* TearJerker: The ending of ''Revenge of the King''. Poor King Dedede. At least, it starts off that way, but becomes a SugarWiki/{{heartwarming|Moments}} moment when his Waddle Dees come up to console him.
* ThatOneBoss:
** Meta Knight. He's incredibly fast, has a lot of hard-to-dodge attacks, has a good A.I. and is a small target. In [[BossRush The Arena]], you can count on him to be the one to kill you (if you're just starting out) or force you to use a Maxim Tomato (if you're already experienced). Not to mention if you plan to do this without an ability, the original game pretty much has him scarce in spawning any projectiles to suck in and spit back out at him.
** Fatty Whale counts as well due to his massive size taking up most of the screen, and his tendency to bounce around.
** Jukid, for being the only boss that has Kirby lose his current ability with one hit, when other enemies and bosses don't require the specific number of times that Kirby is hit in order to lose his ability.
** [[spoiler:Galacta Knight]], especially in The True Arena where Kirby isn't able to heal so easily and projectiles are rare. Like Meta Knight in The Arena (especially as aforementioned like in the original ''Super Star''), he'll usually be the one to kill you or force you to use healing items.
* TheyChangedItNowItSucks: In the ''Ultra'' remake of The Great Cave Offensive, a few of the treasures are changed. Most notably, all 4 Seasonal Hearts are mashed into one treasure (Summertime, Autumntime, and Wintertime were replaced with the [[VideoGame/KirbyCanvasCurse Power Paintbrush]], [[VideoGame/KirbySqueakSquad Triple-Star Cane]], and [[VideoGame/AnimalCrossing Gold Watering Can]] respectively). However, replacing some of the more generic items with {{Shout Out}}s (such as the Sword with the [[VideoGame/FireEmblemAkaneia Falchion]] and the Dud with the Cell Phone from ''VideoGame/KirbyAndTheAmazingMirror'') is usually considered a good decision.
