This is a listing of Official VOCALOID companions and pets
- For a list of VOCALOID mascots, see Vocaloid (mascot).
The term "companion" or "pet" was a term fans (and illustrators) began using as a method of identifying the creatures or objects specifically related to VOCALOID mascots. Some companions have a biography listed on official sites, by the illustrator, or company. The companions also form a starting point for the marketing of merchandise based on the VOCALOID.
The companion has no effect on the software itself and is done purely for decorative reasons.
Companions and petsEdit
In terms of classification, it is generally considered that "companions" and "pets" earn their classification when:
- They have an 'owner' that has a VOCALOID™-powered vocal released. This includes characters from games with vocals powered by the VOCALOID™ software, as well as privately obtained licensed vocals.
- They officially are illustrated with their owner on a software box or website.
By default, characters are sorted from newest to oldest.
NOVA is a little droid companion presented on MAIKA's software box. According to the artist, Noriko, it accompanies MAIKA, is a VFO unit (Voice Flying Object, a pun to UFO) and it was designed to mark a difference in relation to past VOCALOIDs. NOVA acts as a pet, microphone and speaker, and despite being genderless, it's referred to as female. The name for the droid was fan-given, and was chosen based on a small poll started on October 16 through MAIKA's official Facebook page. On December 22, "NOVA" was chosen as the winning name The second most voted name, "Gertrudis", stems from an inner joke in relation to Akuo's insistence that the name of the new Spanish VOCALOID should be Gertrudis.
According to Noriko, the idea of creating a pet for MAIKA was a suggestion from her boyfriend. She tested several "face" designs for NOVA. Among the designs there was a smiley-like face, a simple face with a waveform mouth, and some variations of the current cyclops-like design.
CUBI and Co.Edit
CUBI is a digital cubic companion device that functions as a CD Player, and is presented on YOHIOloid's software box. CUBI is 14 cm tall and weighs 300 gm and has the ability to fly, with the speed measurement of 10 kilometers per hour. The artist, Sartika, originally didn't plan to give him a name, but after seeing that some fans began to refer to him as "CUBI", she stuck with it. According to artist, CUBI can't speak, and the only word he can say is "YO", derived from YOHIOloid's name. YOHIOloid is also the only person who can understand and communicate with CUBI. He cannot change his facial expression, but is still able to show his emotions through other means.
The rest of CUBI's family was later conceptualized, each one with a particular shape, facial expression and function.

"James" is a male American Goldfinch that is presented on OLIVER's software box. The bird was included on the software box because the artist, Dappleback, felt that it made the art look a little more balanced and complimented OLIVER's then to be released design. It is also a little nod to the fact that many Americans worked on this project. The name of the bird was left to be decided amongst the fans and eventually "James" became the popular choice. Despite its popularization, this fan-given name remains unofficial according to VocaTone staff.
James has since developed his own identity and personality apart from OLIVER, this is evident with activities such as being the co-maintainer of OLIVER's Twitter account and being able to 'talk'.  VocaTone also played on James' popularity during the PV Dinky Dink No Time To Think, where he can be seen wearing sunglasses. And on April 1, 2012, VocaTone ran an April Fool's joke announcing that James would become a VOCALOID3 voicebank.
Yukine (ユキネ) is the pet of SNOW MIKU. It was chosen by the public to became SNOW MIKU's pet and designed to fit the Magical Girl theme of the 2014 SNOW MIKU design contest. It was originaly designed by nekosumi and used Ezo Yu and lepus timidus ainu rabbits as motifs. From 2015 onward it was also part of the SNOW MIKU design contests and contestants had to make a design for it too.
