-She tends to crash at your place at night since she wants to cuddle with you since she’s scare of sleeping alone in her bark room also big plus if you have a night light since she never turns it off

Moon-Cake🥮 Anon asked for “Hey can I have some Creepy Miku doll with an even creepier s/o?” Hey again!Sorry this is shorter than the last one but I didn’t really get much energy to do much
Tw : creepy themes,mention of body-gore
Cw : “Creppy” Miku Doll
————————————
“oooh whoo is SHE?a distant meeee-mory🙃❓”
Mainly Romantic
(can be platonic dating)
-Let’s be honest she’s too stupid to notice that your also creepy,she just thought you where normal
-But when she does notice she’s pretty chill with it
-sometimes she pranks people with you by using body-gore,of course it’s not crazy just realistic enough
-Your lucky if she makes a slight difference to her face
-but if you are just someone who doesn’t like creepy stuff then she will just treat you normally
-in general,nothing big has changed
-like at all
You two be like :

Dumb Vocaloid Headcanons Part 1: Internet Co.
All
Andriods/robots of various levels of human resemblance
Voicebank upgrades correspond to hardware upgrades.
Primarily made for music, but they also have combat skills.
Each one has a unique music-related weapon/ability, which I'll elaborate on in another post. (I got this idea from the manga Megu Megu Singer Song Fighter. It's...an experience. Kinda chaotic, and the translation I found isn't always the clearest, but it's cute, harmless fun focused on the first few Internet Co. Vocaloids. If you want to see himbo Gackpo in a fundoshi, this is the manga for you.)
Generally get along well with the Cryptonloids
One huge, generally happy family
Camui Gackpo (Gackpoid)
The most robotic/android-like of the bunch in terms of physical structure, but good gosh, does he have feelings
His "bodysuit" is just what his body looks like (he can morph it into a more human-looking appearance, though), and that weird glowy spot on his chest is his power core.
Can change his eye and power core colors at will
Has a whole army of eggplant horses
A chivalrous gentleman, but he has his goofy moments
An expert in hair care
Cishet ally
Dating/in love with GUMI
GUMI (Megpoid)
Huge science and sci-fi nerd
Has a visible battery gauge on each of her designs, which takes the form of a red jewel. It blinks when her battery is running low. (another idea from Megu Megu Singer Song Fighter)
BFFs with Miku, Luka, Lily, and CUL
Owns a carrot rocket equipped with missiles
Her goggles have several functions, including night vision, tracking, and looking cool.
Lives for the aesthetics of the 1960s-1980s
A little bit scatterbrained, but she tries
Hoping that everyone else (or at least Gackpo and Una) joins her on VOCALOID6 and gets an AI voicebank
Bisexual
Dating/in love with Gackpo
Lily
Beta/production name was Yuripoid (not actually, but in my headcanon). This didn't stick for multiple reasons.
Her tattoo doubles as a battery meter, "draining" from top to bottom as her power depletes.
Likes lollipops (yet another idea from Megu Megu Singer Song Fighter)
The "cool older sister" of the group
Infamous for speeding on her motorcycle
Keeps a couple of beehives, from which she harvests honey
Demi/heteroromantic asexual
Exchanges makeup tips with Gackpo
Ryuto (Gachapoid)
Obsessed with dinosaurs, to the point where he has memorized every species

His arm warmers serve to make his elbow joints slightly less obvious; his shoes do the same thing for his ankles.
Favorite meal is dino nuggies with waffle fries
Friends with Yuki and Oliver
Really wants a pet puppy
Favorite holiday is Halloween
Big fan of FNAF, even if it scares him sometimes
A little bit self-conscious about his buck teeth
Always carries a notebook and markers with him in his backpack
CUL
Huge Madoka Magica fan; cried at Sayaka's death
Doesn't always get along with her sisters, but she loves them all dearly
Gets into arguments with Gackpo over who "stole" the other's hairstyle

kokone
Kind of shy, especially around new people
Huge book nerd; favorite genre is fantasy
LOVES animals
Favorite food is raindrop cake
Surprisingly big fan of horror movies
Gets cold easily
Likes to do prank phone calls with GUMI; they switch places periodically, pretending to be the same person
Trans girl (pronouns are she/her); polysexual
Wants to write and illustrate her own manga series
Rana
Technically developed by We've Inc. as a collab with Internet Co., but since she's the only one from We've Inc, the Internet Co. crew includes her as one of their own.

Just beginning to question her sexuality

ROSA
A CeVIO/upcoming SynthV vocal rather than a Vocaloid, but since she was made in collaboration with Internet Co. and CUL is her older sister, she hangs out with the Internet Co. crew often
Gets along well with Gackpo for their shared love of traditional Japanese culture
Insists that she "was born in the wrong generation"
Loves rose-flavored macarons, but her favorite food is salmon nigiri
Gets picked on by some of her older sisters, so she has learned to be a bit sassy as a defense mechanism
Genderfaer (pronouns are she/her and occasionally they/them); pansexual
In the process of collecting all of the Vocaloid Nendoroids (except the Miku ones; there are way too many)
Dumb Vocaloid Headcanons, Part 2: Crypton Future Media/Piapro
In general
Super futuristic androids built for singing and performing
No combat abilities like the Internet Co. Vocaloids, but they look more convincingly human than the male Poids and CUL (about on par with GUMI and Lily)

Was so proud of Teto becoming a SynthV vocal that she cried a little bit
Also super proud of GUMI kind of becoming the new face of VOCALOID now that Crypton has stepped away
Can be a bit too concerned with helping others; has a habit of overstepping boundaries
Confused by people declaring her the creator of Minecraft and Harry Potter, but rolls with it

Idol Miku AU Explanation
sorry idk how text posts work lol
This is a little preamble to my idol miku's AU and her company and unit: Miku, Rin, Len, Luka, MEIKO, and KAITO are part of the idol unit The Crypton Vocaloids (or The Cryptonloids) who have been slowly adding new talent over the years. MEIKO and KAITO have since retired (who work as managers to the unit now) with Luka close to retirement. Their whole theme is futuristic idols who want to share music with the world!
All of this is of course based on the actual vocaloids IRL, and my attempt on turning their features and fun "gimmicks" into real life counterparts in a believable way. (I have a lot of ideas for each of the characters and their interactions with each other)
I hope this little AU brings as much joy to others as it does to me! If this is something you want to keep up with, I have the tag: Mellows Vocaloid AU with any related posts!
Big Al: If I ate a soda can after finishing the soda.... What would happen?
Kaito: You'll die of course.
Gackpo: You have to try it in order to find out, Mr. FX~
Big Al: *swallows the can whole*
Kaito: Enjoy your stomach ache.....
Kaito: I make ice cream flavors for fun! I end up enjoying the wacky taste too! Yummy yum!
Gackpo: If I see another batch of cauliflower in my brownie blast ice cream, I will personally kick you out of the apartment.
Big Al: I find the taste to be quite lovely. *noms on cauliflower brownie ice cream*
Gackpo: YOU GUYS ARE WEIRD
Kaito: I can go the deepest!
Gackpo: No, I can do better than you!
Big Al: *drinking soda and laughing at them because he can be heard even below C1*
Vocaloid Fandom Headcanons:



(Cuz I can tbh) - General and ship
General Headcanons:
Len pretends to be really manly, but he actually loves watching Magical Girl shows and dancing along with female k-pop idols
Once a year the Vocaloids have a thanksgiving like dinner and they invite the Utaus. They always end up having a “family feud.”
Some Vocaloids like Luka like to pick up small part time jobs for fun. Luka is a fulltime song producer and singer, but she also works at a sushi bar during the weekends.
Len, Oliver, Fukase and Piko have a club dedicated to flexing their songs to each other.
Meiko likes to think of herself as the most mature, she’s kinda like that one aunt who gives you money and drinks wine all the time.
Oliver, Yohioloid, and Leon get homesick and like to visit America and England together whenever they’re not recording.
Piko and Miki claim that they are “childhood friends,” despite not having childhoods.
Ruby and Fukase also claim that they are “childhood friends.”
Every Vocaloid must learn to separate the stories they tell from their actual lives, but many of them believe that some of the songs they sing contain elements from their past lives.
Galaco started a podcast for all the other discontinued Vocaloids to vent and share their opinions.
Miku is the most popular, but that also means she misses out on alot of things. She gets invited to almost everything, but ends up apologizing for being late.
Kiyoteru teaches Yuki, Rana, Gachapoid, Oliver, Aoki, Una, and all the younger kids.
Despite the Macne Family mostly being Utaus, they’re allowed to live in the Vocaloid house.
IA and Merli are best friends and they have tea together whenever they can.
Based on popular vote, it is VFlower’s job to greet new Vocaloids and show them to their room.
Everyone recognizes Leon, Meiko, Kaito, and Big Al as their seniors and go to them for advice. Unsurprisingly, it’s usually awful.
SonIka and Gumi view each other as sisters because of their close debut dates and designs.
Many of the younger girls and even some of the older girls idolize Rin. She is usually very sarcastic about it and doesn’t let it fully get to her head, unlike Len.
Alot of Vocaloids with the same hair color get grouped together, meaning Cul, Fukase, Ruby, and Arsloid spend alot of time together.
Sexualities/Ships:
As Vocaloids, most of them don’t really label themselves or have any views on sexuality, but some individuals have very tradition values.
Lily and Ritsu are dating. Everyone was confused because they heard that Ritsu was a six year old boy who inserted missiles in his breasts and weighs 25 tons, but in the end they just assumed she was trans with a weird since of humor.
Anon, Neru, and Tei are all vying for Len’s affection. Tei thinks she’s winning, but she is in fact, not.
Kyo and Yohioloid are dating. It took Oliver, Wil, and Yuu alot of confused third wheel dates to figure it out.
Miku and Kaito get paired together very often, but in reality they are very close friends. Miku, Kaito, and Luka love to gossip about dates to each other.
Gakupo is painfully single despite having many fans and love interests.\
Yuzuki Yukari and VFlower are very close friends. Some people think they’re dating, but no one knows for sure.
