Not present; Miki, Yuki, Kiyoteru, Lily, VY1, Gachapoid(Ryuto), Iroha, Piko, and VY2.
Left to right: Leon, Sonika, Big Al, Prima, Miriam, Sweet-Ann, and Lola.*
Not present; Tonio, Oliver. Image is a common interpretation of the Engloids by the fandom.
Vocaloids (from "vocal" and "android") are music synthesizing programs based on real human voice samples and technology created by the Yamaha Corporation. There are currently 37 vocaloids (Rin and Len count as one product instead of two); and fans have created personalities for each character based on official art (some have no official art) and voice. Fans have also created characters based on official releases, such as Neru Akita and Haku Yowane.To use a Vocaloid, one simply has to type in the lyrics of the song of his choosing as well as the melody for said song, although a great deal of fine-tuning is usually necessary to have the result sound natural. Vocaloids have become so popular that an official unofficial manga adaptation, Hatsune Mix, was created, telling the trials and tribulations of the Crypton-produced Vocaloid family: Kaito, Miku Hatsune, Meiko, Rin and Len Kagamine, and Luka Megurine.Vocaloid has recently taken major steps to becoming Serious Business*
On the Internet, anyway. Even with it having some recent extensions into the real world, Vocaloid is still a niche thing, even to Japanese who identify as Otaku, with several of them not even knowing there are more Vocaloids than Miku Hatsune.
. Flagship character Miku Hatsune has become a fully-fledged Virtual Celebrity, with an album featuring her work (composed by synthesizer band Supercell) nearly topping the Japanese music charts at No.2, and Miku herself putting on a live concert at Animelo Summer Live 2009. (Her "live" performances involve her image rear-projected onto a glass screen and sharing the stage with a live band. *
)Toyota also began an ad campaign for their 2011-model Corolla, starringMiku herself; it was subsequently revealed that Toyota sponsored Miku's first overseas appearance — a live concert in Los Angeles at Anime Expo 2011.In the 2010 Concert, Rin, Len, and Luka have also made debuts (though no appearance by Meiko or Kaito) with even better renderings. In addition, the Vocaloid song Black★Rock Shooter (which features said character, created by artist huke) has inspired an official anime OVA of the same name, which was produced by animation studio Ordet (ex members of Kyoto Animation) and was released on 2010. Another popular song, "Kokoro" seems to be getting its own musical. "Daughter of Evil", in turn, got its own theater play and later a manga. Recently, "Cantarella" got a musical, too.Miku had yet another overseas concert in Singapore during the Anime Festival Asia 2011 on November 11, 2011.The Vocaloid Character Sheet is here, in addition to the Crowning Music of Awesome page as well as the Nightmare Fuel page (for unintentionally scary stuff) and the High Octane Nightmare Fuel page (for the deliberately scary stuff).The producers cosMo, Deco27, and mothy have their own pages, as does the band supercell and the music-video-making software Miku Miku Dance.
Alice Allusion: Alice Human Sacrifice by Miku, Kaito, Meiko and Kagamine, Alice in Dreamland by Kaito, Persona Alice by Miku, Boku to Alice no Wonderland by Len, Alice by Hatsune Miku. A lot of songs have Alice in Wonderland theming.
Let's not forget A Li CE iN BLACK MARKET by Miku's DARK Append, if only for the title.
Although, considering the amount of logic in most of the songs by the author, it might not be.
According to one interpretation, Mrs.Pumpkin has died and the dream is her being dragged to hell by Satan (the goat).
All There in the Manual: Anything related to the Story of Evil series, going as far as the characters' names, as well some very important facts about characterization and plot, especially including how the twins got separated in the first place and the fact that Rin's character does not remember that Len's character is her brother. Information has been released on Akuno-P's blog along with really really fast flashes of text on the velvet mix versions - and a novel series.
American Kirby Is Hardcore: The homepage for the Miku Corolla advertising campaign. It seems like whoever drew her doesn't like certain ideas of cuteness...
Toyota changed her appearance later, perhaps bowing to pressure from disappointed fans.
A quick google search and now everybody can compareit!
Crypton's Piapro website held a contest for an official "American" Hatsune Miku design last month, and recently declared a winner (made by Exiled Artist). YMMV on the winningresult. Word Of God indicates it will be used "in a commercial basis or in projects related to Miku's next concert".
And Your Reward Is Clothes: Most of Project DIVA - either clothes or room items. Except the clothes are called "modules".
Animated Actors: The easiest way to maintain a solid Fanon is to just assume that the events of the music videos are being acted out by the Vocaloids. That way you don't have to explain how Len keeps coming back from the dead, etc.
Arc Symbol: The grass circlet in one of the PVs for Servant of Evil. Two other PVs replace it with a yellow flower petal and a golden locket.
Ascended Fanboy: In a way. Popular Nico Nico Douga singer Piko now has his own Vocaloid, Utatane Piko, courtesy of Sony Music, besides being a professional singer himself.
As Long as It Sounds Foreign - Kaito's breakthrough song Pane dhiria is written in Japanese and an Arabic-sounding language called Hanamogera. What is Hanamogera? A completely made-up language by the creator.
Attractive Bent Gender: Kagamine Len, in the video forImitation Black. This song became way more popular (not to mention much faster) than any of Natsu-P's other songs on Nico Nico Douga.
Badass Labcoat: Interpretations and fanart of Honne Dell have him in one.
Badass Longhair: Gackpoid. The perceived contrast is intensified with the fact that his hair is purple.
And Kasane Ted, if you count his ponytail.
Badass Teacher: Several fan depictions of Kiyoteru Hiyama make him one of those, as well as they make him a Cool Teacher.
Batman Gambit: A particularly strange, though somewhat heartwarming one is perpetrated by Len in this video. Also noteworthy for being a non-sibling, non-"mirror image" relationship between Len and Rin.
Bittersweet Ending: Hello, Planet, though it's more of a "sweet ending with a little bit of bitterness". Bitter part: Miku dies in front of her master 's grave, not only from damage to her body (from the rain), but sadness, as well. Sweet part: Miku's tears cause the plant to sprout, she reunites with her master in the afterlife, and it's implied that her little plant actually reseeds the whole planet.
The game based on the song actually has two endings: in the alternate ending Miku's singing revives her dead master, and after a tearful reunion the two work together to revive the world with their potted plants.
The demo song of V3's Akikoloid has a serious case of this. A-ki-ko-ro-i-do-a-ki-ko-ro-i-do, Akiko desu. Roido desu. Akiko desu. Roido desu. Akiko desu. Roido desu.
1. It's techno 2. It's based on Diva Desu (Miku), which is a far greater offender.
Both true, but it still fits into the trope.
Butt Monkey: Leon. His most common incarnations are an extremely hairy man and a Nightmare Fuel render of a man that commonly appears in the magazine Leon. Most of his videos are parodies. Kaito can also be seen as this. Half his songs are just parodies of others (though his originals are quite good), and in things like Chibi Miku-san is made fun of all the time.
But Not Too Black: Subverted with Lola: considering that the English Vocaloids' character models are subject to the viewer, her skin color varies from black to white (it's usually one or the other). Played straight with Sweet Ann.
The Cameo: Miku's first anime appearance was one of these in Sayonara, Zetsubou-Sensei, as one of the people auditioning to be Meru's voice.
Rin, Len, Kaito, and Meiko also appear in the same episode briefly, waiting in line for the auditions, however their coloring is off.
Cannot Spit It Out: The whole point of Rin's "I like you, I love you." Subverted in that she does spit it out at the end, but it took a long time to get there.
Cat Girl: SeeU, the new Korean Vocaloid from the V3 series, has cat ears on her headset.
Don't forget Iroha Nekomura! She has a Hello Kitty design, with a big cat helmet and little cat-eared speakers, among other things. Her last name even means "Cat Village".
Conjoined Twins: Rin and Len in Dark Woods Circus, complete with all the Nightmare Fuel and Body Horror you'd expect.
The Cover Changes The Gender: This is averted with surprising frequency — several male Vocaloids have covered Love is War and Romeo + Cinderella, for example, with the very feminine lyrics left untouched. Covers that do bother to change the gender usually dramatically alter the lyrics, often for a Perspective Flip from the point of view of the implied male love interest. This is also the typical practice in fanmade covers.
Covert Pervert: Some fans seem to have a lot of fun portraying Gakupo as such. Kaito as well (Lord Of Darkness, a parody of Daughter Of Evil, is a good example of this). Also Luka, who is a bi/lesbian pervert in Japanese Ninja No.1 (although she may just have been hired by Kaito).
Defictionalization: Gakupo was based of voice samples from Gackt. Then Nico Nico held a vocaloid contest hosted by Gackt where they asked him to sing the winning songs Episode.0 and Paranoid doll. The result was Gackt not only created and released a remix of the song Episode.0. But he also created a pv that was identical to the original Episode.0 pv but with the pictures of Gakupo replaced with pictures of Gackt dressed as Gakupo. Here is the original pv of Episode 0. And here's the Gackt version featuring Gackt dressed as Gakupo Episode 0 Gackt version
In Miku's 39's Giving Day concert, she and the other singers (most notably Megurine Luka) are sometimes singing into handheld mics while clearly wearing headset mics.
Detached Sleeves: All of the V2 Cryptonloids have these, the same with most if not all their derivatives.
Note that in Saigo no Revolver, the bullet hole of the second gunshot landed neatly over Gumi's name in the credits.
That same bullet is shot right when another bullet that was already shot when Gumi shot her lover was over the ??? name. ??? was the one who Gumi killed.
Expressive Hair: In some fan depictions, Miki's ahoge changes shape according to her emotions. Teto's drills can become real drills when she's in berserker mode, too.
Expy: Within its own fandom, there are all kinds of counterparts of the original Vocaloids. Kaito and Miku have the most. Miku even has several that are officially recognized by the original creators.
Fan of Underdofg: Any person who likes any of the UK-loids or Voyakiloids tend to be one of these, some out of pure spite for people who dislike them.
Fan Vids: Any sufficiently popular song will inevitably receive at least one of these.
Fantastic Racism: A surprisingly common topic. The Evil series includes racism based on hair colour, with Haku being shunned for her naturally white hair and all green-haired people being murdered by the princess. The ogre in Ogre and Maiden is threatened with a Torches and Pitchforks mob just for hanging around near the village, and is only able to befriend a blind woman who doesn't know that he's an ogre. (The same "oni" metaphor crops up in The Person who Loves a Demon.)
Witch, by Luka, focuses on her persecution because she's a witch.
The Lancer - Meiko (due to the minor fan war between Kaito/Miku and Kaito/Meiko fans. Meiko can also double as the Token Evil Teammate or Team Mom, depending on how much the fanfic writer likes her)
The Smart Guy - Len (who is also usually portrayed as being more rational than the others)
The Big Guy - Rin (as most fans believe that she's the toughest of the group)
Gay Aesop: Possibly the original version of Magnet. The original version is not clear as to why Miku and Luka's love is forbidden, but the fact that they're both women implies that this is the case.
Gender Bender: Each official Vocaloid has a genderbend, with the exception of Rin and Len, who are each other's genderbend, even Len and Rin, surprisingly enough.
Although the moral behind it might be about how we should treasure the way reality looks... Maybe?
Gratuitous English: "Gugurekasu" has the correct-but-oddly-inflected "Please do not ask me why" and the just odd "All of you wants to know me, I think". Don't forget Miku's "Brack Rock Shoota" and Luka's Crimson Camellia which is full of Engrish. "I CAN'T FRY...I CAN WALK"
"Gugurekasu" also has the final lyric, which most people can't even understand because of its obscurity: "Please search it with this Google."
Similar to "Gugurekasu" is Gakupo and Gumi's same-tune (different key) cover, "Aniimo." While "Please understand my feelings" and "I worry about you, always" at the beginning are grammatically correct (albeit strangely inflected, like "Gugurekasu"), the final "You are only one for me" would be perfect, if not for the missing "the."
It is excusable, however, by the fact that English sounds that do not exist in the Japanese language nor are inflected in the English way are nigh impossible for a Vocaloid to use, Depending on the Writer. This is possibly one of the reasons for Crypton's decision to produce more English-native Vocaloids, starting with a new bank of English phonics for Miku.
It is becoming very common for Japanese artists in the fandom to credit people for the music/lyrics/vocal/special thanks, sic, and to refer to themselves with romaji names.
Megpoid was created with voice samples from Nakajima Megumi (earning her the Fan Nickname "Rankaloid".)
There's also Luka, practically voiced by THE Seiyuu for Tall, Dark and Bishoujo characters: Yuu Asakawa. The fact that she has purplepink hair is also the reason why there are fanarts of Rider cosplaying her.) This carries on to Takoluka as well, Rider and Sakaki versions exist for this reason.
Idiosyncratic Episode Naming: samfree's "Night Fever" series, which will always have the Vocaloid's name (or some variant of it) repeated twice in the name of the song (and it will always have two syllables), followed by a star and some variation of "fever", "night", or "burning/fire".
If You Kill Him, You Will Be Just Like Him: Meiko realises in the Evil fan-song Daughter of Revenge that if she kills Len, she will be taking away the only one who loves Rin, doing effectively the same thing Rin did to her. She kills him anyway, deciding that she's able to live with the burden of being evil if that's what it takes to get her revenge.
I'm a Humanitarian: Meiko in Conchita, the Epicurian Daughter of Evil. And in some versions of Trick and Treat, Rin and Len.
Don't forget Utopia and A Ray of Hope. Humans transferred into Androids may have souls, but not morals, apparently. Eventually deteriorating into ELIMINATE ALL HUMANS.
Or Logic. Because natural humans tend to wage war, the United Nations decided to transfer all humans into androids. Those refused to do so are eliminated to preserve peace. Killing for peace's sake.
Improbable Age: According to this site, the main character in Judgement of Corruption is a talented judge, despite his young age.
Improbably Female Cast: There are currently over twice as many female Vocaloids as male ones; and of the dozen or so males, at least one is close to being Ambiguous Gender. Len is supposedly male, but he's voiced by a woman.
The unfortunate reality is that a man Vocaloid is always a big risk. Kaito flat-out bombed in his initial release, Kiyoteru is easily the least popular of all of AH's products, Tonio barely gets the time of day, and Big Al (by far the best-received of the English Vocaloids) has gotten at best mixed reviews. On top of that, any man who wants to break into the market now will have to compete against Kaito, Gakupo, Kiyoteru, Big Al, and VY2. A few new male ones are in the works, but more and more of the new characters (especially the Japanese ones) have been female.
Insane Troll Logic: With extra information from the songwriter, it is revealed that Meiko in Alice Human Sacrifice was trying to kill everything because she believed it would bring her out of Wonderland. What.
As are Iroha Uta, Romeo and Cinderella, Lollipop Homeroom, and possibly supercell's latest Look This Way Baby.
SPICE!. Can be a little uncomfortable to listen to because it's sung by a virtual fourteen-year-old.
Eh? Ah, Sou. most certainly fits this trope...
There's a lot of debate about whether Two-Faced Lovers (also known as Ura-Omote Lovers) falls into this, or if the translators are just trying to Spice Up The Subtitles.
Isn't It Ironic: Even though Vocaloids originated in England, the Japanese ones are more popular. Strictly speaking, the technology was developed by Yamaha. However, despite Meiko/Kaito being developed from the get-go, Zero-G still managed to release Leon and Lola first. English vocaloids. Before the simpler, easier to record Japanese Vocaloid. From the original company.
There are probably more people who heard of Hatsune Miku than of Saki Fujita, and of Kagamine than of Asami Shimoda; you know, the ones who provided the voices.
I Want My Beloved to Be Happy: Luka's rendition of The Little Mermaid , albeit owing to the source material. Servant of Evil, both if you regard it as sibling love and when you find that when Len saved Miku... he wanted to return her to the blue prince/king...
Meiko even in her past life as the girl's teacher, at first is in love with her best friend in The Thought To Tell. She then attends her best friend's wedding...
''Love is War'' is a subversion. As the title suggests, the singer is willing to do most anything to prevent her beloved from being happy with anyone else.
Japanese Delinquents: The eponymous character of Rolling Girl. Then she falls in love and gets better... sorta. The PV for Project DIVA extend however, turns her disaffection with society into full-blown reality break-down, ala The Animatrix. Doesn't end well for her.
Lighter and Softer: One artist on Nico Nico is known for drawing cute, cheerful PVs for depressing or creepy songs, reinterpreting the stories to make them seem more positive. So far s/he has done this to the Evil series (it turns out the whole thing was a charade to teach the selfish princess a lesson), and Alice Human Sacrifice (Everyone Lives, the twins find and befriend the dream from the beginning of the song, and they all go on a journey to explore Wonderland together).
Loads and Loads of Characters - There's quite a few already and the number is only growing. And that's not even getting into the fanmades and genderbends.
Note that this number increases exponentially. In 2010, the number of Japanese Vocaloids could be counted on both hands, and the number total were still easy to keep track of and to recite without issue. By the time 2012 arrived, the number had almost tripled.
Loads and Loads of Loading: The PSP version of Project DIVA games are plagued with this. Especially if you have the DLCs installed, as it needs to check the license everytime the list of DLC items are loaded. This is Egregious.
. Rin is in love with Kaito, but Kaito is in love with Miku, as is Len; Haku is in a Romantic Two-Girl Friendship with Miku. According to a fan song, Miku apparently reciprocates Len's feelings before he kills her; however, this is proven incorrect by the additional information. Some fanon claims that Kaito and Meiko's cooperation is more than that, but this is generally disregarded.
Love Martyr: Len and Rin are constantly playing this game. Notable examples include the Story of Evil series.
To be fair, she does meet him again, and it's suggested that the plant she took care of reseeded the entire planet.
Iwatte Yaru, a song that talks about how the singer is jealous of everybody with happy and meaningful lives, but instead of cursing them, she'll congratulate them since she knows it will all end anyway. The song sounds more like a Christmas tune. For those curious, both "curse" and "congratulate" translate into words pronounced "iwatte", making the song take on quite a sarcastic feel.
(It's Not) World's End is an almost overwhelmingly cheerful, fast ska-ish song, but the lyrics are the thoughts of someone moments before committing suicide.
Don't Look At Me sounds like a chipper song with toy sound effects and a cute and happy-looking video. The interpretation of the lyrics so far range from suicide to abortion to drug abuse.
Another song from Kikuo-P, Let's Go to Heaven, also qualifies. This happy-sounding song heavily implies that the couple has died by the end of the song, but do apparently reunite in Heaven. Similarly to the *Hello Planet example above, exactly how sad the ending is may vary from person to person.
Meaningful Name: Most official and fan characters. The 'Hatsu' of Hatsune (Miku's last name) means first; she was the first japanese Vocaloid2 character. The 'Kagami' part of Kagamine (Rin and Len's last name) means 'mirror'; Crypton once described them as mirror images instead of being twins, although they backtracked on that. The 'Meguri' of Megurine (Luka's last name) means circulating/revolving; a reference to her bilingual capabilities. Furthermore, the 'ne' at the end of Kagamine, Hatsune, and Megurine means 'sound'. Akita Neru means 'I'm tired; going to sleep' and Haku Yowane means 'weak-willed words'. In fact, the name "Akita Neru" was coined because of the troll who created her using the phrase akita, neru ('I give up; going to sleep'), as a reaction of frustration about the difficulty of using the VOCALOID software.
Lily's voicebank was sampled from the singer Yuri Masuda. "Yuri" means "lily" in Japanese.
Similarly, Gakupo, voiced by Gackt (pronounced Gakuto) and Gumi, voiced by Megumi Nakajima.
Memetic Outfit: Len's dress from Imitation Black. Although just about any clothing of the Vocaloids in any popular song, really.
Mind Screw - Vocaloid songs tend to have a lot of these, but Tower of Sunz deserves a special mention. Eight minutes of black chickens, circus scenes, multiple Mikus and general what-the-fuckery.
Also, Waribashi Onna. The whole thing is about an odd not-Miku girl having a crazy dream about trying to break apart chopsticks, doing something that is censored, then inexplicably goes into a brief talk about politics before she starts running in space with the other vocaloids getting hit by a meteor in the background, trying to hug an angelic Miku, then waking up to eat bad noodles before getting a nosebleed from angel-Miku sticking a chopstick in her nose. It ends with an image of the girl's head on a fish body.
The Putin-P series has to be one of the biggest mind screws in Vocaloid history. Rin works for Vladimir Putin, Len is a dog, and Miku is going out with Ronald McDonald. And that's just the beginning; the series consists of 4 parts with a total of 41 songs.
Miku tries to do this to Luka in scissorsroid, for stealing her master. She is stopped by Luka's love and admiration for her. It's false. Luka takes the scissors and stabs Miku.
Producers who qualify include Machigerita-P, Hachi and mothy.
No Export for You: Many of the non-English Vocaloids are rather difficult to get if you don't live in Japan, and shipping can get to ridiculous prices. Yamaha attempted to avert this with some Vocaloid3 banks such as VY1V3, Mew, and the V3 Gumi banks, Voctro-Labs ships Bruno and Clara internationally, and SBS put up SeeU on eBay (albeit at a considerably higher price), but some, like Yuzuki Yukari, are still rather difficult to get overseas.
No Infantile Amnesia: Played with in Servant of Evil — Len remembers that he and Rin were twins, but Rin doesn't (the two were separated when they were very young).
Not so Different: In Daughter of White, Haku finds that she's unable to kill Rin even after learning of her crimes, because Rin is just like "the old me, a tremendously lonely person".
In the related fan song Daughter of Revenge, Meiko figures out the Twin Switch, and that Len is motivated by love just like she is, but doesn't stop the execution. Seeing Rin in the crowd, Meiko reflects that "you and I are the same" and that she is every bit as wrong as the Daughter of Evil was.
Otaku Surrogate: Gumi is this in Sorry For Being a Closet Otaku.
Our Vampires Are Different: The Lord of Darkness is basically a perverted anemic whose strength might be less than a regular human's. He's even kind of stupid and actually forgets the few special powers that he does have.
P.O.V. Sequel: The Evil Series gets its tear jerkers from these. Servant of Evil tells the events of Daughter of Evil from Len's POV. And there's Daughter of White which tells the story from Haku's POV as the close friend of Miku.
And Leia, where an artist falls in love with a painting.
Rapunzel Hair: Miku, and to a lesser extent Luka, Haku and Neru. Fanartists tend to draw it even longer, to the point of it being longer than the character is tall.
Revenge by Proxy: A common interpretation for Meiko's character in the Evil series is that she figured out the Twin Switch, but decided to go through with the execution anyway in order to get her revenge. There is one well-known fanmade song, Daughter of Vengeance, that runs with this theory.
Especially the V2 Appends and most of the Vocaloid-3's.
Except in the cases of Piko and Miki; both have robotic joints and the former has what appears to be an equalizer as part of his left eye. Oh, not to mention the tail-like USB cable.
Roaring Rampage of Revenge: Meiko in Daughter of Revenge begins a nationwide revolution after losing her family, farm, and lover.
Scary Musician, Harmless Music: Not quite "scary/harmless" but...Sasakure.UK's music tends to be of the "heartwrenching/emotional/philosophical" type. So you'd expect him to be the kind of wise person who broods on this sort of thing, right? Notsomuch...
Shaggy Dog Story: Owata is essentially a song about a Gakupo (or Miku) missing a meeting with a friend and couldn't tell him because his phone was dead. In the end the friend had cancelled.
Noroi no Megane is about a mysterious stranger (Gakupo) giving Rin a pair of ridiculous-looking glasses. With her eyesight already being 20/20 and the fact that the glasses only makes her surroundings look MORE distorted, she goes looking for a way to remove them. She also enlists the help of a doctor and a priest (played by Gakupo) who only adds to the load. When she finally learned that the way to take them off is hidden in a library at a secret island, she finds out that she can't read the map even though she has already prepared the boat. At the end of the song, the stranger visits her again and reveals that the glasses actually give her REFRACTION instead.
1925 makes references to classic 1925 silent films. By 1:10, Charlie Chaplin in The Gold Rush can be seen. Following up is Miku dressed as a sailor in front of what is unmistakably the poster to Battleship Potemkin. This troper didn't recognize the part that came after but has a suspicion of it also being a movie reference of some sort.
This is somewhat emphasized in the Append artwork; Rin's outfit is mainly light with some darker elements, while Len's is mainly dark with some lighter elements. Not to mention the boxart.◊
Silly Love Songs: Cupmen (song for cup ramen) is a sweet, bouncy ditty about a Lethal Chef who desperately wants to cook delicious food for the person she likes, but always ends up making instant ramen "with water heated by the power of love". He's less than pleased but eats it anyway to make her happy.
Many, many vocaloid songs fall under this. Sometimes coupled with Tearjerker.
Slasher Smile: Gumi's grin in Matryoshka can be... disconcerting.
Gumi? Try staring at Miku's grin near the end of 'Matryoshka' without wanting to throw your PC out a window.
It's also visible in the preview version of Judgement of Corruption.
A portion of "Hold and Release, the Rakshasas and the Carcasses" features Miku singing back and forth to herself about how the problems of strangers don't matter.
There's also the numerous Disappearance of Hatsune Miku editions, among them the Kaito video. Just seeing what happens near the end... and then the happy music going on in the background... cue fade into static...
Star-Crossed Lovers: The whole point of the song magnet. Other examples include: Gumi and the guy she's singing about in The Last Revolver, Rin and Len in Prisoner/Paper Plane, Rin and Len (again) in Yume Sakura, Luka and Len in Ryuuren Kagetsu (Floating Love, Shining Moon)... I could go on. Needless to say, this trope happens a lot, especially to Rin and Len, who are really angst-happy.
Theme Tune Rap: Like the old "Pokemon Ieru Ka Na" song that was a rap with the names of all the original Japanese Pokemon, a Vocaloid collab song appeared called Isshu no pokemon ieru no ka! for the new Isshu (Unova) region Pokemon, complete with a few nifty Shout Outs to other Pokémon songs such as the original "Ieru Ka Na" and the Lavender Town theme. Most of the Vocaloids (plus Teto) get to rap their own parts of the song; although sprites were created for Len and Luka for the video, they are notably absent.
And most things in the Yandere section down below.
Together in Death: A fairly common trope, especially where Star-Crossed Lovers are concerned. For example, Rin and Len in Proof of Life/Soundless Voice.
Took a Level in Badass - In Festival of Asylum, in which everyone ends up in a group of demon exorcists (or "The Anti-Masked") against a mysterious Masked Devil, wielding guns. Gets even more badass when Miku gets possessed by the Masked Devil, and ends up using a sword against Rin's gun. (To be fair, Miku loses.)
Gumi in Saigo no Revolver in which she's a badass agent with a gun assigned to kill a man... until she falls in love with him. She still shoots him, even though she goes into depression later and implies she might commit suicide (whether that gunshot at the end was a thematic gun sound a la Noir or her actually committing suicide is up to interpretation; some maintain she never even killed him).
Another Gumi example: DECO*27's "Mozaik Role," which involves her facing off against a shadow of herself. Complete with, at one point, getting speared in the gut and nearly killed by her alter ego. With a freakin' pair of scissors.
In Judgement of Corruption Kaito is heaping amounts of badass for the whole 5 minute video. Not only does he take bribes to hand down innocent verdicts, but he refuses to surrender his fortune for salvation and willingly falls into the deep pits of hell and he takes his daughter with him, resolving to once again gather fragments of the original sins and make hell into a utopia for him and his daughter.
And in that same video we can chalk up another one for Gumi, who is essentially THE DEVIL!
Rin in the FirstVirusResistance Series. So very, very much. Especially in the Restart Chapter.
Commenters have stated that First Virus Resistance is just like The Disappearance of Miku Hatsune, only Rin's all like 'No freaking way' and comes back as an antivirus.
Sf-A2 Miki gets her own in Lience. The song itself gets so fast-paced and action-y that you feel like you're running away from someone trying to kill you. Also, the lyrics are supposedly about her 'hunting' something...
The PV for BLAZE makes Miku and Neru into sword-wielding schoolgirls and has them fight each other, along with all the other Vocaloids and even some UTAUloids.
Everyone in The Secret Police. The police are badass, their outfits are badass, and even the song itself is badass. They're watching you.
Also everyone in re_Cycle. Especially 3:02 - 3:27. That is all.
Kaito has his ice cream (Vanilla Haagen-Dazs), Meiko her sake (One Cup Ozeki), Miku and leeks, Len and bananas, Rin and oranges, Gakupo and eggplants, Luka with her octopus (Takoyaki) and tuna, Gumi with carrots, Miki with cherries, Kiyoteru with chocolate, and Yuki with apples. Some fans base their habits and sexual orientations on this, as Len is a girly boy who likes to eat bananas. The idea of a "character item" carries over to UTAU too (Teto with her french bread) as well as the fanmades and the Engloids (although the latter two rarely use food).
Troll: Some fanmades and UTAUloids are made for this exact purpose; the most famous being the VIPPERloids Kasane Teto, Yokune Ruko and Namine Ritsu, who are April's Fools jokes from 2ch. One who's less of an April's Fools and more of a Take That to some fans who make Mary Sue fancharacters is Kawaiine Kagami, the Annoyloid, who surprisingly uses Gackpoid's voice.
Akita Neru was derived from a troll.
Tei Sukone, also from 2ch, is another example. Her unoriginal design is a Take That at everyone whose UTAUloid's outfit is a Palette Swap of Miku's, her personality is a Take That at fan characters who love Len and hate Miku, and her sharingan is a Take That to Naruto fan characters who have it. Unlike Teto and the other VIPPERloids, however, she is immensely hated by the Fan Dumb who don't realize that she was MADE for trolling.
Tsundere: Meiko and Neru are the most typical ones, although as of recent, Luka has joined them (see Go Google It). Rin is also rather tsundere. As well as Teto (as a type B tsundere). Len is also sometimes portrayed as one (there was even a sister song to Yanderenka called Tsunderenka), especially when paired with another male Vocaloid. Miku is rarely tsundere, but there are exceptions. Basically, Vocaloid fans have a tsundere fetish.
When it comes to specific songs, World Is Mine!Miku and Kocchi Muite Baby!Miku are awfully tsundere.
Every Vocaloid has a chance of being tsundere at some point, due to the nature of the program.
Twincest: Many fans are fond of the Len & Rin pairing.Just as many aren't. Officially, Crypton has stated that Len and Rin aren't twins - they are mirror images. The SAME PERSON. This does not fix it. Also officially, their programmer referred to them as twins, adding more fuel to the fire. Eventually Crypton gave up and referred to them as both mirror images and twins, or whatever the producer wants them to be. The fanwank over this is still going strong.
Twin Switch: Rin and Len do this in the Daughter of Evil series.
And in Monochrome Ward, although the story of it is quite hard to understand.
Token Loli: Yuki. Just Yuki. Also Rin to a lesser extent.
Theme Twin Naming: Rin and Len are puns on "R" (right) and "L" (left).
Vaporware: We haven't heard much of CV04 and its existence since its confirmation in 2009, and details get more and more scant as time passes by...
Villainous Crossdresser: Assuming the Duke is the hero of The Madness of Duke Venomania, Kaito is one of these to him.
Villainous Glutton: Meiko would be considered this in Conchita, The Epicurean Daughter of Evil where she literally eats anything and everything, whether they are edible or not. She even goes as far as eating her two servants, Rin and Len and eventually eats herself
Villain with Good Publicity: Meiko in the Evil series fansong Daughter Of Revenge, from a certain point of view. Sure, she did depose the evil princess who executed anyone who dared speak against her...but she also killed a comparative innocent simply because he cared about the princess, and Meiko wanted Rin to feel the pain of losing absolutely everything that one loves. In the last verse she explicitly compares herself to Rin, saying that "even if I am called a heroine, I, too, am a Daughter of Evil".
Visual Novel: "All the Songs With You in the Future," a worksafe story about Hatsune Miku, was created and sold through DLSite, and translated by fans into Chinese, Russian, and English. The same creators made a story about Rin Kagamine called "Rin ga Utau, Mirai no Neiro," and it also has on-going fan translations.
Wholesome Crossdresser: Whenever VanaN'Ice has a music video, Len is in a dress. He also does this when he pulls a Twin Switch with Rin in Servant of Evil.
And Kaito may actually be this in Venomania, if the Duke is the villain.
Word Salad Lyrics: Some songs tend to fall into this trope. One example being the song "AHS Funky" in which "AHS"(as in AHS Software) stands for Asian Hong Kong Shocking.
Luka's Love Disease. Starts off with what seems like Luka striking up a happy relationship with someone, but then it turns out to be just daydreaming...then she finds out her crush is dating someone else and she's not pleased about it at all...and then those eyes...
Rin in much of Putin-P's songs, especially noted at the end of I'll Give You Chocolate! although that side of her seems to have calmed down, or at least hidden in the more recent songs
Your Cheating Heart: Gift From the Princess Who Brought Sleep has Kaito cheating on his wife Miku and going after other girls. Miku corrects this by poisoning him to death/eternal sleep ... and everyone else in the town and eventually herself.
In The Tailor Shop on Enibzaka, the tailor is unhappy that her lover has been unfaithful and doesn't return home to her. On three separate occasions, she sees him with different girls who all die mysteriously throughout the story. Finally, she confronts her lover Only for him to not recognize her and she murders him. It turns out he had never met her and her "lover" was already married and had two daughters, who were all murdered by the tailor.
Zettai Ryouiki: Hatsune Miku is a slight variation, as it's not her socks, but her boots. Subsequently, many Miku spin-offs have this as well, and they're straighter examples most of the time since the boots are traded in for normal boots and stockings.
