History YMMV / KirbyAndTheForgottenLand

** Lab Discovera's [[spoiler:announcer isn't the first time human voice acting was used in a Kirby game. Not counting the [[Anime/KirbyRightBackAtYa anime]], there was actually a decent amount on ''VideoGame/KirbysEpicYarn'' thanks to the narration in the cutscenes, ''VideoGame/KirbysAvalanche'', with the occasional voice lines playing during matches and the announcer in ''VideoGame/KirbyBattleRoyale'']]. That said, this would be the first time it's a diegetic element.

** On the topic of vocals, the fact there is [[spoiler:''actual human voice acting'' in the game, specifically the recordings in Lab Discovera and the Forgo Land, selling just how ''alien'' the people that lived in the new world are compared to the ''Kirby'' norm, considering this kind of voice acting is almost entirely absent from the franchise. The only prior examples were the [[Anime/KirbyRightBackAtYa anime]], ''VideoGame/KirbysAvalanche'' (which was more EarlyInstallmentWeirdness), and ''VideoGame/KirbysEpicYarn'' (which was done to fit the game's storybook-like tone).]]

** The bass riff of Waddle Dee's Weapon's shop sounds similar to that of [[Music/EltonJohn "Step Into Christmas" by Elton John]].
** The map theme for Wondaria Remains and the stage theme for The Wondaria Dream Parade are obvious homages to the [[Ride/DisneyThemeParks Main Street Electrical Parade]]'s "Baroque Hoedown".
** The second measure of [[https://m.youtube.com/watch?v=cMifkHeyl-0 the song]] that plays when the FinalBoss [[spoiler:brings Popstar and the New World on a collision course]] sounds like the "[[https://m.youtube.com/watch?v=e1QKpmfcfaQ Catastrophe]]" theme from ''VideoGame/SuperMarioGalaxy''.

** [[spoiler:Morpho Knight]] has an InterfaceScrew attack which turns the camera 90 degrees while keeping your directional controls the same, which can make aiming your attacks much harder.

** After the game's release, a common theory among fans is that the original inhabitants of the New World [[spoiler:became the Ancients of Halcandra who built the Lor Starcutter, Nova, and Star Dream, having traveled to and settled there after harnessing the technology to imitate Elfilis's dimensional warp abilities before abandoning it. Some have even noted a resemblance between Elfilis's containment facility and the interior of Nova. Tying in with the earlier Shiver Star theory, Shiver Star is also thought to be another one of the Ancients' settlements that was also abandoned, perhaps even the one they traveled to immediately after leaving the New World.]]

* IAmNotShazam: The setting of this game isn't called "the Forgotten Land", but rather the New World. [[spoiler:Leongar]] does refer to it as the former during his pre-battle monologue, but it's more of a descriptor ("this forgotten land") than a proper name. In Japanese, however, [[spoiler:the final BossOnlyLevel of the game ''is'' called "[[{{Pun}} Forgo-tten]] Land".]]

* UnintentionallySympathetic: The BigBad, surprisingly enough for [[VilerNewVillain one of the most evil antagonists in the entire franchise]], is regarded with sympathy by sections of the fanbase due to [[spoiler:what happened to them when they were captured by the researchers of Lab Discovera]]. Without added context from the Japanese text and the [[AllThereInTheManual Perfect Support Guide]], what's mentioned in-story is that [[spoiler:Fecto Elfilis allegedly tried to invade the New World, was forcibly captured and experimented upon for 30 years, split into Fecto Forgo and Elfilin during an experimental accident, and has been imprisoned in the Eternal Capsule for an unspecified length of time (after being [[ComeToGawk used as a tourist attraction]], at that) while the planet was abandoned, with only the repetitive voice of the Dream Discoveries Tour announcer -- a voice that is shown to [[TraumaButton appear deep within Forgo's subconscious]] -- for company.]] [[AlternateCharacterInterpretation Some fans believe]] that [[spoiler:Fecto Elfilis's violent behavior throughout the entire last act of the game came about in part as a result of them [[GoMadFromTheIsolation going insane]] from experiencing the FateWorseThanDeath of what was essentially solitary confinement]] -- and that's if they don't assume that [[spoiler:Elfilis came in peace and was only captured because the scientists were wary of a ''potential'' AlienInvasion, not an actual one.]]. Granted, [[spoiler:the Eternal Capsule definitely didn't help Fecto Forgo's [[AxCrazy already tenuous sanity]], but in context, such a fate was [[AssholeVictim well deserved]].]]

* IAmNotShazam: The setting of this game isn't called "the Forgotten Land", but rather the New World. [[spoiler:Leongar]] does refer to it as the former during his pre-battle monologue, but it's more of a descriptor ("this forgotten land") than a proper name.

* MemeticPsychopath: Because of Kirby's reputation for [[ManipulativeBastard being betrayed by characters who initially seem friendly]] (namely [[VideoGame/KirbySuperStar Marx]] and [[VideoGame/KirbysReturnToDreamLand Magolor]]), people quickly began theorizing and joking about [[CuteIsEvil Elfilin secretly being evil]] long before the game even released. Jokes range from him cheerfully telling Kirby outright that he'll be the final boss to Kirby just being suspicious and keeping his distance from Elfilin until his innocence is proved. [[spoiler:As it turns out, this is only half-true; Elfilin is the "good" half of an incomplete being, Fecto Elfilis, who ends up becoming the final boss. Elfilin ultimately pulls a HeroicSacrifice to stop Elfilis from destroying everything.]]

** [[spoiler:Chaos Elfilis's "soul" form]] has their MeteorSummoningAttack, which fully exploits Kirby's flight limitations in this game. It starts with a massive meteor shower that requires avoiding the shadows on the ground, but during this, a number of meteors stack up in one spot to create rock spires of varying heights. Kirby needs to ''quickly'' platform up to the highest stack, because [[spoiler:Chaos Elfilis]] follows this up with a fiery charge that covers the entire arena and can only be dodged by being as high up as possible. They do this twice in a row before changing to other patterns.

*** However, the Japanese version includes some nuances in the Dream Discoveries Tour speech that refute this interpretation and make the character seem [[TheDreaded vile and dangerous from the word "go"]], namely that [[spoiler:Fecto Elfilis's invasion attempt was initially targeted at the New World's [[BadPeopleAbuseAnimals defenseless animals]]. Following that, Elfilis either ended up causing such widespread damage or was so gratuitously violent (it's not exactly stated) that Lab Discovera became "anxious about the risks" to their civilization, deciding to capture it as a sort of GodzillaThreshold before it could attack them next.]]

** While ''Forgotten Land''[='s=] localization is a noticeable and much-appreciated step up from the translation of [[VideoGame/KirbyStarAllies the previous game]], an endgame remark that [[spoiler:Elfilin is the "missing half" of Fecto Elfilis]] is often taken ''literally'' to mean that [[spoiler:he represents ''exactly'' one half of Fecto Elfilis's original mind, being the [[MadeOfGood purely good]] half to Fecto Forgo's [[MadeOfEvil purely evil]] half]]. The Japanese version never says such a thing, using the much more metaphorical word [[spoiler:''kataware'', meaning "missing/broken piece" or "part of a whole",]] to describe him. To put it another way, the localization words it in a way that implies [[spoiler:Elfilin and Forgo are each a LiteralSplitPersonality of Elfilis]], while the Japanese says that [[spoiler:Elfilin is a tiny EnemyWithout that embodies [[AllLovingHero pure, all-encompassing love]], with Forgo representing every other part of Elfilis]]. The English localization makes this more clear in other areas, i.e. [[spoiler:Fecto Elfilis's figure description reading "The Elfilin we first met was born from a small, compassionate soul that hid behind greater, invasive ambitions,"]] making this a one-off slip that nonetheless affected the perception of the characters.

** Sword has always been the JackOfAllStats in terms of Copy Abilities, but its evolutions turn Sword into the most powerful it's ever been in the series. Gigant Sword is basically Hammer with better range and even comes with a spiked shield when you guard that, [[AttackItsWeakPoint despite the]] [[InTheBack ability's namesake]], renders you fully invulnerable to all standard attacks (the tradeoff being that you cannot dodge with this ability) on top of being able to move while guarding, albeit very slowly. The spikes on the shield even do slight contact damage. Its charge attack stacks up with Hammer Flip on top of having better range and a slight shockwave effect. Meta Knight Sword ups the speed of a lot of its attacks and gives Kirby access to {{sword beam}}s, allowing for quick damage at a distance provided you have full health (or have the extra lifebar powerup active). [[spoiler:[[InfinityPlusOneSword Morpho Knight Sword]] is faster than the Meta Knight Sword, can grow to be even larger than the Gigant Sword when charged, it's capable of healing Kirby when using certain moves on enemies, gives Kirby a significantly improved dodge where he goes totally intangible for a good second, and its power and speed levels are already maxed, ''yet can still be upgraded to up its power past the maximum'' -- PurposelyOverpowered does not BEGIN to describe it. Though at that point in the game, the only real challenge left is Ultimate Cup Z and the final BonusBoss.]]

* FanartAtFirstSight: The second trailer featured Kirby fighting a female leopard boss named Clawroline. No sooner after the direct the trailer was in ended, Twitter was flooded with fanart of her.

** One Website/{{YouTube}} comment puts the FinalBoss in a different light; [[spoiler:was Elfilis truly malevolent, or did they come in peace before the inhabitants of the New World ''attacked them''? Then, after a brief struggle, during which the story was twisted to make ''[[HeroWithBadPublicity Elfilis]]'' seem like the bad guy in this situation, the alien was captured and experimented on for more than thirty years, with the constant cheery voice of the tour guide finally driving them completely to insanity, unable to escape the voice of the tour guide even in their dreams. It would explain Fecto Forgo’s [[{{Determinator}} undying will]] to escape Lab Discovera, their attempts growing increasingly desperate as they doggedly refuse to be put back in that situation again, and in the end would mean they tragically [[CreateYourOwnVillain became the very villain the New World's inhabitants made them out to be.]]]] However, the Japanese version includes some nuances in the Dream Discoveries Tour speech that refute this interpretation and make the character seem [[TheDreaded vile and dangerous from the word "go"]], namely that [[spoiler:Fecto Elfilis's invasion attempt was initially targeted at the New World's [[BadPeopleAbuseAnimals defenseless animals]]. Following that, Elfilis either ended up causing such widespread damage or was so gratuitously violent (it's not exactly stated) that Lab Discovera became "anxious about the risks" to their civilization, deciding to capture it as a sort of GodzillaThreshold before it could attack them next.]]
*** This also paints the action of trying to [[spoiler:collide Popstar into The New World in a different light. Was Elfilis really doing it out of spite? Or did they decide that they would rather [[BetterToDieThanBeKilled get obliterated by a planet collision]] or [[SuicideByCop by Kirby's hand]] than be [[FateWorseThanDeath trapped in that test tube again?]]]]

** The second phase of the postgame final boss [[spoiler:has a special move where it fires several claw-swipe beams in a row followed by its laser-breath. This comes out fast, but is predictable and leaves it wide open afterwards. However, while Kirby is rushing to attack, Soul Forgowarps near him and lets out "Soul Crash", an expanding explosion that fills almost the entire room, dealing rapid damage while trapping him until it expires. The only way to avoid it is to get to one of the edges of the arena depending on the explosion's position. It's one of the few times in the game where the camera can cause issues during a boss fight, as it can be hard to figure out exactly where Soul Forgo warped to and then get to a safe spot in time]].

** While ''Forgotten Land'''s localization is a noticeable and much-appreciated step up from the BlindIdiotTranslation used in [[VideoGame/KirbyStarAllies the previous game]], an endgame remark that [[spoiler:Elfilin is the "missing half" of Fecto Elfilis]] is often taken ''literally'' to mean that [[spoiler:he represents ''exactly'' one half of Fecto Elfilis's original mind, being the [[MadeOfGood purely good]] half to Fecto Forgo's [[MadeOfEvil purely evil]] half]].

** In the post-game King Dedede refuses to speak to Kirby, with one of the Waddle Dees explaining that the King is upset about Kirby going off to rescue the Waddle Dees. Is Dedede mad at Kirby [[ItsAllAboutMe for not making his rescue the top priority?]] Or is Dedede mad at ''[[MyGreatestFailure himself]]'' for needing to be rescued and not being the one to save his subjects? Given that the Waddle Dee also explains Dedede is thankful for Kirby's actions and his silence is simply resting up from his wounds, the latter seems like the more likely scenario.

* If you go out of bounds during the fight with the 2nd form of the TrueFinalBoss, you'll respawn back into the arena along with a copy of their 1st form.[[note]]You can have up to 6 of them at once before the game crashes due to all the visual effects.[[/note]] Unsurprisingly some players decided to use this glitch to create a SelfImposedChallenge where the player tries to fight against 2 or more copies of the TrueFinalBoss, turning the entire fight into a BulletHell nightmare due to their usage of BeamSpam and other attacks.

* CommonKnowledge: Right before the FinalBoss: [[spoiler:The Dream Discoveries Tour says that Elfilin split off from Elfilis 30 years after research began on Elfilis, not 30 years prior to the present day, as it's sometimes misinterpreted. It's unknown how many years elapsed between Elfilin splitting off and the present day. Even the Music/JunoSongs adaptation gets this wrong, with the lyric "thirty years, and here we are".]]

* ThatOneBoss: Sillydillo is a pretty large difficulty spike with many fast and hard-hitting attacks, including a cage that he can trap Kirby in and OneHitKill him if he doesn't escape in time, giant dance partner dolls that can home in on Kirby, and a rolling move that pretty much ''demands'' dodging. It also doesn't help that he spends much of the fight constantly moving around the battlefield, making him hard to hit and wasting precious time for players who want to complete the timed mission. That's not even counting how wildly he makes the camera spin around the arena during his second and ''third'' phases, and being the only three-phase boss in the main story. In a June 2022 ''Nintendo Dream'' interview, [[WordOfGod Kumazaki]] admits that ''even some of the developers'' thought he was too hard!

* MoralEventHorizon: The FinalBoss crossed this by revealing [[spoiler:they mind-controlled Leongar into [[SlaveryIsASpecialKindOfEvil enslaving hundreds of Waddle Dees]], then [[TheAssimilator assimilating Leongar and several members of the Beast Pack]] — [[UngratefulBastard without any care for their genuine efforts to help them]] — just to get to Elfilin and consume him as well to [[UltimateLifeForm complete themselves]].]] If it that wasn't enough, then they''definitely'' did cross it when, in an act of desperation, [[spoiler:they decide to open a giant portal to Popstar with the intention of [[ColonyDrop causing the two populated planets to crash into]] and [[OmnicidalManiac destroy each other]]. All simply [[EvilIsPetty to get rid of Kirby and his friends]]]].

** The ending to [[spoiler:Chaos Elfilis's fight]], where [[spoiler:Elfilis turns into a tiny speck of light that gets absorbed by Elfilin]], has led to many interpretations of [[spoiler:Elfilis]]'s character. The associated figure description says that [[spoiler:Elfilis's soul willingly returned itself to Elfilin]], but fans are unclear on whether this means [[spoiler:Elfilis is a GracefulLoser who pulled a proper HeelFaceTurn, or that they're still evil and they finally [[PyrrhicVictory got what they wanted]]. A third camp thinks that they simply [[KnowWhenToFoldEm knew when to give in]] to their heroic half, regardless of their alignment]]. The Japanese, Chinese and Korean versions are a bit more clear in some areas, and less so in others: these versions say that [[spoiler:Elfilis was ''reborn'' as a speck of light, but do not mention that Elfilis "willingly" returned to Elfilin]].
** One Website/{{YouTube}} comment puts [[spoiler:Fecto Elfilis]] in a different light; [[spoiler:was Elfilis truly malevolent, or did they come in peace before the inhabitants of the New World ''attacked them''? Then, after a brief struggle, during which the story was twisted to make ''[[HeroWithBadPublicity Elfilis]]'' seem like the bad guy in this situation, the alien was captured and experimented on for more than thirty years, with the constant cheery voice of the tour guide finally driving them completely to insanity, unable to escape the voice of the tour guide even in their dreams.

* BreatherBoss: [[spoiler:Fecto Forgo]], being in between [[spoiler:[[PreFinalBoss Leongar]] and [[FinalBoss Fecto Elfilis]]]], is one of the easiest bosses in the game despite the memorable shock factor of its introduction and a not-insignificant creep factor. Its two attacks are slow and easy to dodge, and it doesn't have a second phase or a lot of health. [[spoiler:This is likely invoked, because it's in its incomplete form and its real form is [[ThatOneBoss much worse.]]]]

* CommonKnowledge: [[spoiler:The Dream Discoveries Tour says that Elfilin split off from Elfilis 30 years after research began on Elfilis, not 30 years prior to the present day, as it's sometimes misinterpreted. It's unknown how many years elapsed between Elfilin splitting off and the present day.]]

* DracoInLeatherPants: The BigBad, [[spoiler:Fecto Elfilis]], is perhaps the nastiest villain in the entire franchise, being [[spoiler:a sociopathic alien invader who enslaves the Waddle Dees, assimilates the Beast Pack when they are no longer of use to them, and even attempts to kill Kirby by [[ColonyDrop hurling a planet at him]] out of spite at losing.]] But if you look at fanart of them from the Japanese fanbase, you're just as likely to see them [[https://cdn.donmai.us/sample/81/7d/__elfilin_and_fecto_elfilis_kirby_and_1_more_drawn_by_user_syfr4477__sample-817d271982e09632b11c5e434dcf2e3a.jpg trying to cut a cake]] or [[https://cdn.donmai.us/sample/0f/8b/__kirby_meta_knight_king_dedede_bandana_waddle_dee_elfilin_and_1_more_kirby_and_1_more_drawn_by_panchracomeon__sample-0f8bc188839796f3963187d7d1cced90.jpg eating apples with Kirby and friends]]. This character's significant [[EvilIsCool wow factor]] and traumatic backstory (if you ignore the fact that they [[AssholeVictim brought it upon themselves]]) probably has something to do with it.

** When Elfilin the RidiculouslyCuteCritter was introduced, the entire fanbase started to theorize that he is evil due to the series having a slight trend of seemingly cute and innocent characters [[VideoGame/KirbySuperStar betraying]] [[VideoGame/KirbysReturnToDreamLand Kirby]].[[note]]This is despite the fact that there have only been two characters in the entire series who were introduced as friendly before ultimately betraying Kirby and both of them just stand back and let Kirby do their dirty work after being the ones to prompt Kirby to go on the adventure in the first place. Every other new ally ends up accompanying Kirby on his adventure, and Elfilin isn't even the one who instigated Kirby's adventure, at least not directly.[[/note]] [[spoiler:Everyone was proven wrong when it's shown that he remains loyal to him, and even performs a HeroicSacrifice in the game's ending to close off the connection between worlds. He does, however, wind up being the final boss -- not out of his own free will, though, and it's more that he's just ''part'' of it.]]

* EvilIsCool: [[spoiler:Fecto Elfilis might be a heartless alien invader]], but their design, theme, and fighting style are nothing short of awesome.

** Certain abilities (Fire and especially Hammer) can perform a super-jump by exploiting the physics of their attacks, letting them bypass the height limitations put on Kirby's flight. This enables a number of skips and ways to get out of bounds. In particular, using a super-jump on [[spoiler:Chaos Elfilis]]'s second phase can trick the game into thinking the battle just started, and cause it to spawn another copy of the boss's first form. An alternate usage of the super-jump is to enter the Colosseum when no cups are selected, which starts a glitched one-round cup that can be used to grind Rare Stones faster than any other method.

* LikeYouWouldReallyDoIt: [[spoiler:Dedede’s HeroicSacrifice to save a single Waddle Dee before battling the Beast Pack by himself]] is certainly heartwarming and tearjerking, but you didn’t think they’d ''actually'' [[KilledOffForReal kill him off]], did you?
* MagnificentBastard: [[NonStandardCharacterDesign Sillydillo]], the "[[BossSubtitles Armor-Plated Prancer]]", is a deranged-looking armadillo working for the Beast Pack. After Kirby's main ally Elfilin is captured, Sillydillo lures Kirby into his lair with a doll resembling Elfilin. Battling Kirby, Sillydillo tries to capture him in a cage, and even utilizes [[MadArtist a "dance partner" he made out of junk]] when his health gets low enough. Loyal to his King, Sillydillo [[spoiler:makes a HeelFaceTurn at the end when Leongar is saved]]. [[BewareTheSillyOnes In spite of his comical nature]], Sillydillo proves himself to be quite the crafty adversary.

* MoralEventHorizon: [[spoiler:Fecto Forgo crossed this by revealing they mind-controlled Leongar into [[SlaveryIsASpecialKindOfEvil enslaving hundreds of Waddle Dees]], then [[TheAssimilator assimilating Leongar and several members of the Beast Pack]] — [[UngratefulBastard without any care for their genuine efforts to help them]] — just to get to Elfilin and consume him as well to [[UltimateLifeForm complete themselves]].]] If it that wasn't enough, then [[spoiler:they ''definitely'' did cross it when, in an act of desperation, they decide to open a giant portal to Popstar with the intention of [[ColonyDrop causing the two populated planets to crash into]] and [[OmnicidalManiac destroy each other]]. All simply [[EvilIsPetty to get rid of Kirby and his friends]]]].

* NightmareRetardant: Sillydillo is tame compared to [[spoiler:Fecto Forgo]], but everything leading up to his lair and fight can be extremely unsettling. However, once he starts to pull out a doll during his third phase, the cutscene ends up making the battle either very funny or [[ThatOneAttack very annoying]] rather than scary.

** [[spoiler:The announcer in Lab Discovera]] isn't the first time [[spoiler:human voice acting]] was used in a Kirby game. Not counting the [[Anime/KirbyRightBackAtYa anime]], there was actually [[spoiler:a decent amount on ''VideoGame/KirbysEpicYarn'' thanks to the narration in the cutscenes, ''VideoGame/KirbysAvalanche'', with the occasional voice lines playing during matches and the announcer in ''VideoGame/KirbyBattleRoyale'']].
** Some newcomers to the series have said that the game's finale involving [[spoiler:a [[SurprisinglyCreepyMoment terrifying]] fight against an EldritchAbomination]] is a nice change of pace from the typical ''Kirby'' formula. Among the fanbase, however, it's [[VileVillainSaccharineShow just another Friday]], especially considering [[VideoGame/KirbyStarAllies the previous game]] had [[spoiler:what's heavily implied to be a ''{{God|OfEvil}}'']] as its final boss. Though the distinct [[BodyHorror Sci]]-[[TheAssimilator Fi]] presentation of [[spoiler:Fecto Forgo]] is seen as a welcome change of pace, as pretty much all of the prior [[spoiler:EldritchAbomination enemies, even Star Dream]] tended to have a distinct fantasy aesthetic much like the rest of the series.

** Clawroline, the female leopard boss that was briefly shown off for the February 9th, 2022 WebVideo/NintendoDirect, instantly caught attention from the furry fandom thanks to her [[SexyCatPerson very attractive design]]. She swiftly gained fanart mere minutes after the Direct's conclusion. [[spoiler:She only got more popular after the full game revealed that she's an AffablyEvil PunchClockVillain who's only fighting Kirby to protect Leongar, and she makes a HeelFaceTurn to help save him in the post-game.]]
** Elfilin also has a few furry fans who were smitten by his adorable design and loyalty to Kirby[[spoiler:, even performing a HeroicSacrifice to close off the connection between Popstar and the New World after Fecto Elfilis' defeat]].
** The BigBad, [[spoiler:Fecto Elfilis]], has a positive reception among furries by virtue of [[spoiler:its sleek, brightly colored design, which incorporates the features of [[MixAndMatchCritters lots of different animals]]. For example, it has a fox's tail, deer-like horns, and a fluffy fur "scarf" around its neck]]. Some have jokingly compared it to fursonas they've seen elsewhere on the internet.

** The game relies very heavily on mashing the Control Stick on several instances of the game's stages or boss fights. On a console infamous for its Joy-Con Drift, many people aren't fans of a few of the Mouthful Modes relying on this or requiring Control Stick mashing to escape some boss attacks. [[spoiler:The final boss requiring this to free Elfilin from its back and dragging the fight longer if the player fails these inputs just adds salt to the wound.]]

* SelfImposedChallenge: [[GoodBadBugs By exploiting a glitch with the hammer ability]], [[spoiler:it's possible to fight both Chaos Elfilis and its second phase simultaneously after taking out Chaos Elfilis once. Even though the fight is a bit glitched up, many people have wanted to attempt fighting both at the same time to make for an even harder secret final boss]]. This can be taken even further to where [[spoiler:more than one Chaos Elfilis can be spawned]].

** The second measure of [[https://m.youtube.com/watch?v=cMifkHeyl-0 the song]] that plays when [[spoiler:Fecto Elfilis brings Popstar and the New World on a collision course]] sounds like the "[[https://m.youtube.com/watch?v=e1QKpmfcfaQ Catastrophe]]" theme from ''VideoGame/SuperMarioGalaxy''.

** [[spoiler:The Forgo Dreams version of]] Fleurina has her creating a clone of herself, then she and her clone both home in on Kirby as they spin around the battlefield. They cover up so much space as they do so that it’s nigh-impossible to avoid getting hit without dodging.
** Halfway through the second phase of the [[spoiler:Forgo Leon]] fight (it can happen again if the fight drags on for too long afterwards), the boss starts a special move where it fires several claw-swipe beams in a row followed by its laser-breath. This comes out fast, but is predictable and leaves it wide open afterwards. However, while Kirby is rushing to attack, [[spoiler:Soul Forgo]] warps near him and lets out "Soul Crash", an expanding explosion that fills almost the entire room, dealing rapid damage while trapping him until it expires. The only way to avoid it is to get to one of the edges of the arena depending on the explosion's position. It's one of the few times in the game where the camera can cause issues during a boss fight, as it can be hard to figure out exactly where [[spoiler:Soul Forgo]] warped to and then get to a safe spot in time.

** One Website/{{YouTube}} comment puts [[spoiler:Fecto Elfilis]] in a different light; [[spoiler:was Elfilis truly malevolent, or did they come in peace before the inhabitants of the New World ''attacked them''? Then, after a brief struggle, during which the story was twisted to make ''[[HeroWithBadPublicity Elfilis]]'' seem like the bad guy in this situation, the alien was captured and experimented on for more than thirty years, with the constant cheery voice of the tour guide finally driving them completely to insanity, unable to escape the voice of the tour guide even in their dreams. It would explain Fecto Forgo’s [[{{Determinator}} undying will]] to escape Lab Discovera, their attempts growing increasingly desperate as they doggedly refuse to be put back in that situation again, and in the end would mean they tragically [[CreateYourOwnVillain became the very villain the New World's inhabitants made them out to be.]]]]

** Once it became clear that the villains of the game, the Beast Pack, were UpliftedAnimal{{s}}, many fans began to theorize that they were somehow related to other animal characters such as King Dedede, [[VideoGame/KirbysDreamLand2 the Animal Buddies]], and [[VideoGame/KirbySqueakSquad the Squeak Squad]]. [[spoiler:King Dedede was indeed revealed to have a connection to the Beast Pack (though it was only because he got brainwashed), but it's still unknown about the other two groups, since neither appear in this game.]]
