YOHIOloid is an English VOCALOID developed and distributed by PowerFX Systems AB. in collaboration with VocaTone, and was released in September 2013 for the VOCALOID3 engine. His voice is provided by the Swedish singer, YOHIO, who provided an English and Japanese voice bank. He was expected to be released early May 2013, but was delayed.
The name "YOHIOloid" is taken from his provider "YOHIO" and 'loid' from "VOCALOID". The stage-name for the provider, "YOHIO", is itself is taken from YOHIO's middle name "Johio".
On VocaTone's Tumblr it's mentioned that YOHIOloid has no given name, although they talked about fans referring to him as "Hio" or "Yohi". It's also mentioned that members of VocaTone have often referred to him as "Hio" in official talks. 
The name in the reference sheets for the little creature alongside his official artwork is "Cubi".
An art related contest was held for YOHIOloid's cover art. The winning illustration became the cover art and official image of the YOHIOloid DVD; the artist received $300, a VOCALOID3 Editor and a signed copy of the DVD by YOHIO. Four runner-ups, chosen by PowerFX, recieved a finished copy of the DVD. The rules for entering are available on YOHIOloid's homepage.
Announcement of the winner was meant to be held on the 22nd of April 2013. According to the report, the reason for the delay was because YOHIO wanted the artist to change one element about it to his favourite thing. On the 24th of April, the winner was revealed to be Sartika Nurhasanah. The runner-ups for the contest were later revealed to be Crealle, Noriko Hayashi, Celes Artemisatto and Camber Poon.
Though not as overall as well met as Oliver, a couple of his demo songs received over 50,000+ views and most of them at least gained 10,000+ views, putting him above the VOCALOID2 English vocaloid releases.
