History YMMV / Vocaloid

** Are Len and Rin Main/HalfIdenticalTwins, [[AlternateSelf alternate selves]], {{opposite sex clone}}s or just {{identical stranger}}s? It all depends on the song and there's no one true definite stance on the subject[[note]]Crypton did provide an official stance at one point, remarking that the Kagamines were mirror images, but they rolled back on this in favor of keeping their relationship vague due to fan backlash[[/note]]. There are also some songs that don't depict Rin and Len as two people at all, but the same person under different aliases.

-->'''Kaito:''' No matter how so many people replace me, even on this wide route\\
'''Len:''' We were able to pair without hesitation, it's caused by you and me\\
''(later...)''\\
'''Both:''' Until we can resonate with each other again\\

** The PV for Halyosy's [[https://www.youtube.com/watch?v=pXLnKaiDeVw "Flyway"]] shows Len and Kaito gently holding each other while gazing lovingly into each other's eyes. Halyosy leaves it somewhat unclear if the meaning of the song is meant to be taken as romantic or platonic (the song itself is about coping with someone you care about leaving for an extended period), but the visuals are intimate enough that it's easy to draw [[YaoiGuys certain conclusions...]]

** Some fans tend to feminize flower's V3 design by giving her additional curves and downplaying her boyish appearance.

For tropes related to Music/HatsuneMiku, go [[YMMV/HatsuneMiku here]].

** Claiming that the Crypton Vocaloids originated from ''VideoGame/HatsuneMikuProjectDiva'' and ''VideoGame/ProjectSekai'' is a very quick way to rile up fans.

** All over the place, due to the [[BlankSlate nature]] of the Vocaloid as BlankSlate. Kaito, for example, has been interpreted as a [[TheCasanova suave ladies' man]], a [[TheDitz total goofball]], an AxCrazy {{Yandere}} and a powerful hero in various fanworks. This trope is taken up to eleven in the RhythmGame ''VideoGame/ProjectSekai: Colorful Stage'', in which the Crypton Virtual Singers' personalities vary heavily depending on which SEKAI [[note]]World born from the collective feelings of each [[OriginalGeneration main group]].[[/note]] they appear in.

** Robotic tuning versus Realistic tuning. Some find the robotic sounding voices to be a part of what makes Vocaloid charming compared to real singers, while others find the robotic tuning to be offputting and prefer the characters to have more natural sounding voices instead. This debate would especially heat up when Crypton left Vocaloid because [[CreativeDifferences the former wanted to keep the voices robotic, while the latter wanted to embrace more realistic sounding vocals]].

** In the olden days of Vocaloids popularity, [[SixthRanger Gumi and Gakupo were treated as a part of the Crypton Vocaloid group]], to the point that some people had begun to believe they ''were'' from the same company.

** While it is true that Vocaloids gained a massive popularity boost in Japan that helped spread its usage wide, it didn't ''originate'' there. The first couple of Vocaloids were English-speaking and were used as background singers for certain projects as well, such as using LOLA in ''Anime/{{Paprika}}''.

** Applies to all of the Crypton Vocaloids, as they're the most recognizable of any Vocaloids' released and each has a dedicated fanbase that supports them as they would real idols.
** Original fan-made derivatives turned semi-official Vocaloids Haku Yowane and Neru Akita are both very popular with fans, to the point that they are more popular and recognized than some of the ''actual Vocaloids''.
** IA can be considered this, as she was the first Vocaloid released to have broken Miku and Gumi's reign over the NND charts due to her association with Jin's Kagerou Project series. Though she's since been dethroned by v flower, she still remains one of the more popular and beloved characters and is still seen with the Crypton and Internet characters in fanworks fairly frequently.
** Bizu, the cartoony, imp-like character featured in the "Snobbism" PV by Neru, is so well-loved and iconic that he gets just as much fanwork as many of the Vocaloids themselves. It's not uncommon for fanart to depict Bizu alongside the Vocaloids, and even people that hate original-character-focused [=PVs=] will make an exception for "Snobbism".

** Confusing Vocaloids with their competing software counterparts ([=CeVIO=], [=SynthV=], UTAU) is a sure way to get swiftly corrected.
** Crediting a song to the Vocaloid who sung it instead of the producer who actually made it (like for example, crediting World is Mine to Hatsune Miku instead of Ryo and Supercell) has become this in more recent memory and making such a move will likely get you swiftly corrected by irate fans.

** Lesser known Vocaloids or Vocaloids with lesser known providers sometimes get the derisive nickname of "Wholoids" or "Literally Wholoids".
** Crypton's Vocaloids are often referred to as "Cryptonloids" by fans.

* {{Fanon}}: Vocaloids might just be the greatest example ever of this trope. Absolutely nothing save for the designs and the voices were determined by WordOfGod. Crypton ''even'' backpedaled on their statement that the [[MeaningfulName Kagamines were mirror images]].

** Due to the English Vocaloids released before Sonika not having a full body avatar, the fandom takes it upon themselves to sketch up various designs for the Engloids. A similar situation is displayed when fans design an image for [=VY1=] and [=VY2=], as they are the first Japanese Vocaloids to not have a full body avatar on their boxart, similar to Leon and Lola. Fans of the pair often also associate them with the characters in their design contests, Kobushi Kiku and 66 (pronounced "Roro"), though 66 is used more often than Kobushi in art.

** While some [=VOCALOIDs=] get redesigns for updated installments, they're rarely accepted over their original design. For example, Hatsune Miku's [=V2=] design is treated as the definitive design for the character despite the various design updates she received after it, with this being extended to even how Crypton promotes her themselves. However, flower got hit hard with this trope when her [=V4=] design came out; many artists vastly preferred her short do and boyish looks compared to her goth-rock ensemble for [=V3=], to the point where it's rare to see fans acknowledging her original design. Flower got hit with this again when her Talkloid design came out, giving her a mix of a feminine but also tomboyish appearance. That said, while the design is once again more popular than her [=V3=] design, it still has yet to overtake flower's widely accepted [=V4=] design.

** Despite being competing software, Vocaloid fans are fairly lax about the existence of Cevio AI, NEUTRINO, [=SynthV=], and other singing synthesizer software, so much so that you can find many songs that use them in "Vocalopost" tags on social media without issue. It likely helps that many Vocaloid producers have begun to use Cevio AI along with Vocaloid recently, including using both in some songs.

** While GUMI is meant to be a [[GenderFlip guy]] in "[[https://youtu.be/V8Ym3wzRU0A First Love Academy]]", which centers around a love triangle in which Len and GUMI fight for Rin's love, the fact that GUMI is officially a girl and her voice remains unchanged in spite of the GenderFlip, means the triangle in the song can easily be interpreted as a BisexualLoveTriangle, with GUMI being a {{Bifauxnen}} instead of a guy.

** While GUMI is meant to be a [[CrossDressingVoices guy]] in "[[https://youtu.be/V8Ym3wzRU0A First Love Academy]]", which centers around a love triangle in which Len and GUMI fight for Rin's love, the fact that GUMI is officially a girl and her voice remains unchanged in spite of the GenderFlip, means the triangle in the song can easily be interpreted as a BisexualLoveTriangle, with GUMI being a {{Bifauxnen}} instead of a guy.

* FaceOfTheBand: For most non-Vocaloid listeners, Vocaloid ''is'' Miku. And it's not for nothing, as she is the biggest [[CashCowFranchise cash cow character]] to be born out of the software, having several video games, various mobile apps, live concerts, [[UsefulNotes/MikuMikuDance software that was created to be focused on making music videos for her]], and tons of merch. She's no slouch when it comes to non-commercial things either, as she simultaneously has the 13th highest tag count on Pixiv at over ''500 thousand'', beating out the VOCALOID tag itself which is primarily filled with fan-art of her, along with having the highest fan-art count of any character on the website. She's also currently the only Vocaloid [[Music/HatsuneMiku to have a separate page]] on this very wiki.

* BetterThanCanon: Many original Vocaloid have cover songs sung by other Vocaloids. Many of these covers are regarded as better than the original ones.

** The UTAU Namine Ritsu's version of the song "-ERROR" by niki has largely overshadowed the original version, which was sung by Lily. Same goes for "The Wanderlast" by [=sasakure.UK]=], which was originally sung by Luka.

* AccidentaNightmareFuel: [[https://www.youtube.com/watch?v=Y7a0hRXCuqg Vocalawson Desu]]. [[BrokenRecord Dear]] [[UnintentionalUncannyValley god]], Vocalawson Desu.

* UnexpectedCharacter: Along with [=Vocaloid6=] dropping out of nowhere without any prior notice or advertising leading up to it, no one expected GUMI of all voicebanks to be one of the first voicebanks released on the program, let alone for her to be an AI voicebank.

* UnintentionalUncannyValley: The Vocaloid voices can certainly dip into this, if their composer doesn't play a few tricks with their voice quality first.

** For some, any Vocaloid song can qualify because of the lack of tonal variation that doesn't come with a natural speaking/singing voice. It's very easy to tell apart a human voice and a Vocaloid voice.

** Kokone got comparisons with her predecessor Gumi after her demo was released. It doesn't help that both are from the same company (Internet Co). Unfortunately, it was also repeated during Chika's release, with the added handicap of being released within the same timespan.

** KAITO, MEIKO, and Luka are starting to gain traction as this as well, being the three oldest looking Crypton characters. Similarly, it's not uncommon to see Miku paired with both Kagamines.

** While Rin/Len was once a FanPreferredCouple pretty much everywhere, this was flipped on its head in the western fanbase in recent years due to the rise in young moral crusaders in fandoms and the spread of the now common misconception that Rin and Len are canonically considered siblings. Admitting that you ship the pair or simply do not care that others do will get you questionable looks in the best-case scenario and even outright attacked if you stumble across the wrong crowd. As well, like most things when it comes to Vocaloid "canon", the fact that [[WordOfGod Crypton]] has acknowledged the ship and even passively supports it in their official media tends to be ignored by those that are vehemently against both the ship and anyone that likes it.

* FunnyAneurysmMoment: Luo Tianyi, Yan He or [=SeeU=] doing a cover of "Senbonzakura" if you see it in [[UsefulNotes/FirstSinoJapaneseWar a]] [[UsefulNotes/SecondSinoJapaneseWar Chinese]] and [[UsefulNotes/KoreansInJapan Korean]] perspective. The song was actually removed from the Korean release of ''[[VideoGame/HatsuneMikuProjectDiva Project Mirai DX]]'' specifically to avoid this.

* FetishRetardant: [[https://www.youtube.com/watch?v=t6M2ppKwuZY "Nehanshika"]] features AbsoluteCleavage bearing Miku and [[ShirtlessScene shirtless]] Gakupo. [[EyeScream Not nearly]] [[MindScrew as hot]] [[HumanoidAbomination as it sounds]].
