The pink puffball with the huge appetite has faced his fair share of [[AwesomeBosses/VideoGames awesome bosses]] over the years. After all, the games generally have [[EasyLevelsHardBosses harder bosses than levels]].

* Anytime you fight Meta Knight, especially when using a sword.

* It really only counts because of the nostalgic value, but the final battle against King Dedede is ''incredibly'' awesome. It's what started the rivalry.

* Fighting Dedede is generally awesome all around, but perhaps the crowning one was in the ''Adventure'' remake, ''Nightmare in Dream Land'', mostly because of how huge he is.
* Nightmare, especially considering the race against time for his first form, his demonic second form, and several strong attacks.

* Mr. Shine & Mr. Bright return from the prior game with all their old tricks and a couple new ones like the devastating Eclipse attack. And this time around, the duo is one of the later bosses rather than an early WakeUpCallBoss, putting the player on a much more even playing field for the fight.
* Dark Matter takes Nightmare from above and adds in a sword duel in low orbit around Pop Star before transforming into its iconic spherical form which would go on to become one of the most recognizable villains in the franchise. Said form is a race against time while the mass of darkness shows off a wide array of new tricks.

[[AC:''VideoGame/KirbySuperStar'' and ''[[VideoGameRemake Kirby Super Star Ultra]]'']]
* Computer Virus is probably one of the most hilarious bosses in the series. Sure, it ain't the hardest fight, but anyone who's got any experience playing [=RPGs=] will have a chuckle at it. Puffiness, Level Up!
* The battle against Marx in the final part of "Milky Way Wishes". It's even more fun if you try to defeat him without using any abilities whatsoever (it is possible), which ups the awesome factor even more.
* Marx Soul from the True Arena. It's Marx, more powerful, more awesome, and most of all, more insane. His maniacal laugh, crazy rolling eyes, attacks that homage Drawcia Soul and final scream as he falls apart all make him both awesome and (relatively mild, but still) terrifying.
* The Arena's '''[[ZeroEffortBoss Waddle Dee]]'''. [[MemeticBadass Come on, everyone knows he's the hardest boss in any game ever!]] It gets replaced with Bandanna Dee in ''Ultra'', who is also fought in "Revenge of the King".
* Any of the bosses from "Revenge of the King" count, mostly due to them [[TookALevelInBadass taking a level in badass]], but special mention goes to [[TheBusCameBack Kabula]]. After going through Crush Clouds, you'd expect to go straight to Castle Dedede again. Nope. As Kirby's flying to Mt. Dedede on the warp star, he's shot down by Kabula. In a last-second save, the three stars you've collected from the bosses form the Starship from "Milky Way Wishes" to help you destroy Dedede's warship. In fact, this is one of the few bosses that gets special pause screen text, which means the game itself acknowledges the awesome!
* Masked Dedede in ''Ultra'', for being a really souped-up fight against original Dedede (he's got an awesome mechanical hammer and the fight takes place in an electric cage) and having [[SugarWiki/AwesomeMusic an uber-awesome remix of Dedede's theme (which is already awesome in its own right)]].
* Think the Wham Bam Rock (Great Cave Offensive final boss) isn't awesome enough? Meet Wham Bam Jewel (Helper to Hero final boss), its stronger counterpart made of gemstones. Aside from having Rock's normal attacks, he also brings out some new ones like flying flaming fists, dropping big bombs and shooting beams from his fingertips. Especially daunting against the harder-to-use helpers such as Wheelie or Rocky.
* Galacta Knight, the final boss of "Meta Knightmare Ultra". Think Meta Knight as an angel... a really powerful angel. Oh yeah, we did mention that you fight him as both Meta Knight and Kirby, right?

* Cloudy Park's boss, Ado. It's a nice fight, or rather, ''five'' nice fights. Ado paints up four bosses from ''Dream Land 2'' (Ice Dragon, Sweet Stuff, Mr. Shine and Mr. Bright, and Kracko) to fight Kirby for her, making it a great nostalgia trip for those who played that game, and it has a lot more depth than most bosses. Also, the fifth fight? Ado herself, attacking in a fit of rage after you defeat all her drawings. [[ZeroEffortBoss She dies with a single hit]].
* Zero's original incarnation is from this game, and it attacks by shooting its own blood at you. And this is a ''Kirby'' game we're talking about.

* While most of the mid-bosses in the game are just larger enemies, every level in Pop Star ends with a fight against a possessed version of one of Kirby's to-be allies. They're all fun battles, taking inspiration from earlier games. Waddle Dee acts like a traditional ''Kirby'' mid-boss (it's one of the few fights in the game that uses the iconic "impact stars"), Adeleine is a simplified version of the Ado fight (drawing up normal enemies, the Ice Dragon, and Dark Matter), and Dedede is a simplified version of his ''Dream Land 3'' fight. Unfortunately, they can only be fought once per save file and aren't in Boss Endurance.
* HR-H, the boss of Shiver Star. It's a HumongousMecha that fights from the background, firing missiles and sweeping lasers while swinging its arms around. And when it gets to half health, it TurnsRed in a manner unlike any prior boss: it transforms into HR-E, a rocket ship with scissor arms that chases Kirby down the pathway. It really shows how the game's TwoAndAHalfD design can make for a unique boss.
* Miracle Matter, a bizarre shapeshifting twenty-sided die who is capable of mimicking all of Kirby's abilities in some shape or form who can only be [[BarrierChangeBoss damaged by whatever ability he's mimicking at the time.]] ([[GuideDangIt Good luck beating it if you haven't figured that out]].) There's seven different forms he uses to attack you, some of which are honestly pretty hard to avoid, he switches forms at random, and he can only be hurt (and even then it's only a slight chip off the HP bar visible at the bottom) when he's in the middle of attacking you. Still one of the lengthiest, most interesting fights in the whole franchise. [[SugarWiki/AwesomeMusic The music's pretty rad too]]. Unfortunately, it's not on the OST.
* 0[[superscript:2]] is some ''serious'' MoodDissonance with almost the entire rest of the game, considering the SugarWiki/AwesomeMusic that served as the BGM, the AmazingTechnicolorBattlefield (dark and drab unlike the backgrounds of pretty much every other level in the game), and the UnexpectedGenreChange to a rail shooter. And the boss itself is a giant, winged eye with a halo and a sickeningly-green tail. The eye is also bleeding.

* Mega Titan -- one of the few bosses in the franchise who cannot be damaged by the conventional "Pick any ability and attack relentlessly" method. Unless you enter the fight with the (rather underpowered) Spark or Beam abilities, the only way to beat Mega Titan is by [[BossArenaIdiocy smacking him into the electrified walls of his arena]]. These same walls also happen to instantly destroy any loose ability stars, should you have your ability knocked out of you by one of Mega Titan's difficult-to-dodge attacks.
* The somewhat-easy but still insanely cool boss battle with [[VideoGame/SuperSmashBros Master Hand and Crazy Hand]] at the same time.
* The battle with [[spoiler:Dark]] Meta Knight before fighting the final boss is incredibly cool. Then again, anything involving Meta Knight is cool.
* [[spoiler:Dark Mind]]'s star barrages nearly put Nightmare to shame, and it bouncing lasers off of its mirrors is an extremely chaotic and tough-to-dodge attack. For such a confusing game, beating the snot out of the final boss is a very satisfying way to cap it off. It culminates in a shoot-em-up, and once you bring its health bar to zero, the credits roll and you can still beat on it.

* Drawcia. Tough as nails when you first fight her, especially if you have no clue what you're doing. Once you've figured out how her attacks work, though, she's an absolute ''blast'' to fight against, and easily worth playing the game again and again just to repeatedly fight her.

* Mecha Kracko stands out for having two health bars (not even the final bosses have more than one), making the arena hazardous in its second phase, and having widespread attacks (that collaborate with the arena to send Kirby straight into pits). It's potentially the hardest boss in the game despite being the third one, but it's welcoming in what is otherwise an easy game with standard bosses.
* Although the final boss, [[spoiler:Dark Nebula]], may be very underwhelming, it can make you appreciate the penultimate boss all the more. [[spoiler:Dark Daroach]] uses upgraded attacks from his first encounter, acts much quicker, and warps around so fast that landing a hit is a challenge if you aren't using an overpowered ability. It's far more deserving of the title of final boss than [[spoiler:Dark Nebula]] is, and while it's not on par with other climactic fights in the series, it's still very fun.

* Squashini is a very unique fight. Especially with the giant roulette (when it isn't completely aggravating).
* Yin-Yarn[[spoiler:'s second form]]. [[spoiler:First form]] isn't so bad either.

* Goriath is an excellent boss battle, paying homage to several famous manga such as ''One Piece'', ''Naruto'', and ''Dragon Ball''. [[spoiler:His EX fight even has a Spirit Bomb attack!]]
* Grand Doomer. Basically a KingMook for all the Sphere Doomers. He comes out of nowhere and uses attacks unlike any other enemy (other than Doomers), and the fight ends with [[spoiler:Grand Doomer shielding itself so that Kirby has to use the Ultra Sword on him]]. It serves as a great final boss [[spoiler:[[DiscOneFinalBoss before moving to Halcandra]]]].
* Metal General is pretty good. He fights like Meta Knight, but uses his own, mechanical attacks, as well, including generating giant rockets that he uses to ram into you. [[spoiler:In Extra Mode, after beating the Metal General EX, he summons HR-D3, the robot from the Kirby Quest minigame in ''Mass Attack'', which he redesigned in his image. That's right; he managed to take Dedede's own Humongous Mecha. And, considering the first form, it's highly likely it was designed after Kirby 64's HR-E.]]
* Landia, the boss of the seventh and final world. It's just as Magolor said, a fierce four-headed dragon who shows no mercy to any who disturbed it. Some of his attacks are taken from Red/Great Dragon (one of the Computer Virus' monsters), like the flame breath or the "gigantic wing flaps". It's even better in the second phase where it splits into four smaller dragons, with awesome, hard to avoid {{Combination Attack}}s.
* Right before the final boss, you'll be fighting [[spoiler:Lor Starcutter]] in a SHMUP battle, riding [[spoiler:each heads of the split Landia]]. Its attacks are based upon [[spoiler:the missing parts that you spent your time collecting, like the oars flying at you or the mast shooting out tornadoes]], and then some.
* Kirby's finishing move against [[spoiler:Magolor]]. So much Sword. And after you barrage him with that Ultra Sword, [[spoiler:he goes even more OneWingedAngel and turns into a big, black sphere of darkness with big red eyes. His stomach is pure white with an eye that resembles Dark Matter.]] This is without going into [[spoiler:the Extra Mode version]]. Quite a few of his attacks homage Marx's, too. Oh, and in the second phase, he pulls out ''Super Abilities'' against you. [[ See for yourself...]]
* Galacta Knight returns as a BonusBoss, being fought in the True Arena as the third to last opponent. Unless you saw his picture in the end of the Extra Mode Credits, this fight is only foreshadowed by easily missed details in the appearances of Stone Kirby and Metal General. The fight itself is... mediocre at best, until, like many bosses in the game before him, he TurnRed. His theme music kicks in and he starts wiping the floor with you with upgraded versions of his previous attacks and throwing out new attacks.
* ''[[MilestoneCelebration Kirby's Dream Collection]]'' gives us [[spoiler:Smash Combat Chamber EX, a Boss Rush with every miniboss from ''Return to Dream Land'' and Whispy Woods EX. Kirby fights them with the Smash Ability, which is basically his ''[[VideoGame/SuperSmashBros SSB]]'' moveset, making a return from ''Kirby And The Amazing Mirror''. And the songs that can play include the True Arena boss theme from ''Kirby Super Star Ultra'' and Miracle Matter's boss theme from ''Kirby 64''. Alone, they're great. Together, it's amazing.]]

* The second boss, Paintra, falls into this, especially for everyone who's played ''Canvas Curse'' or knows of earlier art-based bosses in the series. She has a lot of varied attacks that take advantage of her theme, such as painting obstacles on canvases (including copies of Landia and herself). Especially nice with 3D on, due to her paint splatters and streaks covering the screen.
* Kracko's back in Old Odyssey, and he's not messing around this time. Once the second phase of his fight starts, he swaps his classic ''Super Star'' moveset for a much crazier one, using massive electrical attacks and sprouting drill-spikes. It's also the only fight in the game that uses the plane-switching mechanic-- Kirby can hop in the cannons that Kracko drops to pursue him into the background and back. Kracko also appears in ''Kirby Fighters Deluxe'', where he sticks to one plane but adds more drill-spike attacks.
* The fourth boss, Coily Rattler, isn't derived from an earlier ''Kirby'' boss, making it a unique fight. It's a SegmentedSerpent, and most of its attacks take advantage of this, such as curling into a wheel or separating itself into pieces. While Coily Rattler is hard to hit, it also attacks fiercely and quickly so the fight stays engaging.
* Prior to the final battle, [[spoiler:Masked Dedede]] makes a return... but after [[spoiler:his hammer]] is broken after an average boss battle with the usual theme, he becomes [[spoiler:Masked Dedede's Revenge]]. Think [[spoiler:Masked King Dedede]] with a massive power boost and as a replacement to his hammer, is willing to use a battle axe three times his size. AND the remix of his very theme from ''Super Star Ultra'' plays as a ThemeMusicPowerUp! And just wait until you see his Mirror World counterpart, [[spoiler:Shadow Dedede]], who doesn't even need the mask to show how tough he is! To top it off, when he TurnsRed he not only switches to the massive axe, but also combines the attacks from [[spoiler:Super Star Ultra's Masked Dedede]] and [[spoiler:Dream Land 3's Dark Matter possessed Dedede]].
* The final battle. [[spoiler:Dreamstalk Queen Sectonia vs. Hypernova Kirby.]]
** The fight with [[spoiler:Queen Sectonia herself]] is very cool as well, as they possess a wide variety of attacks and different phases to the fight. [[ The awesome music backing up the fight]] doesn't hurt either (OminousPipeOrgan + HeavyMetal = [[AwesomeMusic/{{Kirby}} AWESOME!]])
* This game's answer to [[spoiler:Galacta Knight]] is [[spoiler:Dark Meta Knight from ''Amazing Mirror'']], and he's just as awesome. [[spoiler:ThemeMusicPowerUp and everything.]]
* In ''Kirby Fighters Deluxe'', Dedede is once again the final boss... except that not only is he going with up to ''61'' smaller copies of himself, he also upgraded his hammer with the power of Star Rod, to the point of being able to pull off [[spoiler:Shadow Dedede's attacks]]. All this while the tune of the title screen and, later, the medley of Dedede's boss themes from previous games are blaring.

[[AC:''VideoGame/KirbyPlanetRobobot'' ]]
* Clanky Woods, if only for spectacle. The game takes Whispy Woods, near-universally known as a complete wimp of a boss, and turns him into a mechanical force with drill feet and missiles. Despite being the first boss, it's a very dynamic fight, unlike any previous Whispy battle. Special mention goes to the second phase, where Clanky makes the arena circular; a feature that hadn't been seen since ''Crystal Shards''.
* Holo Defense API, the second boss, is awesome for the same reason as Ado: it's five fights in one. It summons holographic Kracko and Ice Dragon like Ado, while also throwing out Sphere Doomers and Coily Rattler. Lastly, when all those four are beaten, it goes frenzy and flies around in the arena. Again, like Ado, you can beat it with one final hit... but good luck hitting something that moves that fast.
* In the second Jet Robobot stage, Kirby faces off against C.O.G.S. again. It goes exactly the same as before, with the catch that [[spoiler:upon defeat, Kabula, the original Unexpected Shmup Boss of the series, emerges, now sporting a laser along with its original weapons]].
* The fifth boss starts out against a clone of Dedede. It quickly becomes a fight against three of them. When they're beaten, [[spoiler:they jump into a cannon, accompanied with another remix of Dedede's theme mixed with the ending to "Revenge of Meta Knight" (in a way to homage the ending of "Revenge of the King").]]
* The beginning of the final boss gauntlet is [[spoiler:an upgraded Mecha Knight, complete with a remix of Meta Knight's theme from ''Super Star''. For his second phase, he unleashes a giant claw to attack with]].
* The supposed final boss of the game, [[spoiler:President Haltmann]]. Take [[spoiler:Susie's mecha]] and turn it up to eleven, and that sums the fight up. While the battle itself is very crazy and exhilarating (boasting ''four'' phases and some very stylish attacks), a lot of the appeal comes from [[spoiler:Haltmann]] himself. His insane EvilLaugh and very... unique attacks (most clearly [[spoiler:destroying his own minions with a laser dome]]) really shows what kind of character he is. Coupled with the music, it manages to be one of the most unsettling fights in the series, and since [[spoiler:Haltmann]] is relatively tame in appearance compared to other ''Kirby'' villains, it's quite the accomplishment.
* The entirety of the final boss is made of awesome. It starts out with [[spoiler:Susie knocking the helmet off Haltmann's head, allowing Star Dream to [[CyberneticsEatYourSoul overwrite Haltmann's memories]]]], and [[spoiler:Susie, not expecting things to have gone that way, leaves Robobot Armor for Kirby, and Meta Knight arrives with the Halberd, allowing the Robobot Armor to ABSORB it]]. The battle itself is a Star Fox-style shoot-em-up, with [[spoiler:Star Dream]] having plenty of lasers, a meteor shower attack, and even shielding itself with a heart-shaped barrier. And after that, [[spoiler:it fuses with the Access Ark, and becomes the largest thing Kirby's ever had to face]], that fires off rings, the letters to spell out "HAL" in reverse, [[spoiler:the Access Ark's legs]], and spherical lasers that explode. And after that, [[spoiler:the last little bit of the Access Ark's shell comes off, revealing a face similar to that of [[VideoGame/KirbySuperStar GALACTIC]] [[PhysicalGod NOVA]], and even begins attacking with parts of the original Nova to boot!]] Oh, and after that, [[spoiler:Star Dream fires a laser at the Halberd, requiring Kirby and the Robobot Armor to be ejected, and ends in Kirby [[ThisIsADrill DRILLING]] straight through Star Dream as a last-ditch attack!]] And [[spoiler:in the True Final Boss variant, Star Dream Soul OS, as Kirby prepares to drill through it again, Star Dream inhales Kirby for an on-foot version of the Galactic Nova fight. After three waves of pillars, the heart subverts being a Background Boss and attacks directly, using attacks inspired by other Soul bosses (primarily Marx Soul) as well as unique attacks.]] And finally, [[spoiler:after depleting its health, it still uses a desperation attack before finally dying.]]
* The final gauntlet for Meta Knight. After fighting an upgraded Haltmann, [[spoiler:Star Dream pits Meta Knight against clones of [[VideoGame/KirbysDreamLand2 Dark Matter]] and [[VideoGame/KirbyTripleDeluxe Queen Sectonia]]. After they fall, Star Dream summons the real Galacta Knight, who promptly disables Star Dream and attacks Meta Knight. In addition to his attacks from ''Return to Dreamland'', he can also summon a huge laser. All this comes in addition with a techno remix of his theme]].
* ''VideoGame/TeamKirbyClashDeluxe'' (the Eshop expansion of the subgame) ends with [[spoiler:King D-Mind, which is essentially Shadow Dedede from ''Triple Deluxe'' being fully possessed by Dark Mind from ''Amazing Mirror''. He combines both of their attacks with frightening proficiency, making it a huge challenge even with a full party.]] The game also gives us a proper fight with Taranza, and he is ''no pushover'', pulling out a host of completely new moves that make him on par with a few endgame bosses. [[spoiler: His mirror counterpart, Dark Taranza, steps it up even further.]]
