But out of the multiple characters that are part of Vocaloid’s lineup, there are some that are the best because either they were popular or maybe because the history behind their design and conception is interesting and makes them stand out from the rest.

So here are the top 10 best Vocaloids of all time, ranked.

10. Meiko

Meiko sold well compared to Kaito during her initial release and is loved by Vocaloid fans. She was the first character to have an official avatar and was ranked within the top 10 most popular Vocaloids back in 2015. While she remains popular among fans, it was announced that there won’t be any future installments of her voicebank.

9. Piko

Piko shared the same name as the artist his vocals originated from — Piko — and was released in conjunction with Piko’s release of his second single. His voicebank was developed under Sony Music Entertainment Japan, so the recording label held tight control on how his voice is used. So if you’re wondering why there aren’t that many songs using his vocals, that’s why. There was barely any promotion and the avatar was only accessible on the day his vocals were released. But dang, people were able to produce really smooth vocals using his voicebank.

8. Dex

Dex is a unique Vocaloid character because — unlike other characters whose voices come from Japanese artists — his belongs to an American Vocaloid producer named Sam Blakeslee, aka Nostraightanswer and Lupin. His initial design was inspired by The Fox and The Hound and was modeled after a wolf, but eventually was scrapped in later releases. Dex was the first native Vocaloid available for Mac users and his vocal usage in English tracks is really smooth and not jarring at all.

7. Gakupo

Gakupo’s design was based on a samurai aesthetic and was marketed toward professional song producers to take advantage of accessing vocals from famous singers. Gakupo rose in popularity in Japan due to the lack of male vocals available, and unlike most other Vocaloids, his name is based on the artist his voices came from, GACKT (Kong: Skull Island – Japanese Dub).

6. IA

IA is a Vocaloid that was released post-2010s, with the goal to make her sound natural and not robotic when used by music producers. IA’s voicebank was designed to be easy to use and provide crystal clear vocals. Whether or not that goal was achieved depends on you. But the fact that this Vocaloid character was a featured guest at a 2016 anime convention in Sydney probably proved that her vocals are loved by both music producers and fans alike.

5. Megurine Luka

Luka was the first Vocaloid character that was designed to provide both Japanese and English vocals. And while she’s usually seen singing along to Hatsune Miku, she’s still iconic performing on her own. Unfortunately, Yamaha announced that Luka’s voicebank will go to retirement as no new serial codes will be distributed. But just because she’s no longer accessible doesn’t mean she’s unloved.

4. Kaito

Kaito was once described as a “commercial failure” due to the lack of interest in his first release. However, his popularity rose in 2008 when his voicebank sold twice as much compared to his initial release and was well-received later on in future releases. An interesting fact about Kaito was that his vocals were provided by famous Japanese singer Naoto Fuga, known as one of the featured vocals for the Pokémon Sun and Moon theme according to Discogs. So it’s pretty cool to know that an iconic Japanese artist voiced a popular Vocaloid character.

3. Gumi

Gumi has one of the most natural voicebanks in Vocaloid and can sing in both English and Japanese. Her design has a retro-future aesthetic to it, yet still looks adorable when she needs to. She can be peppy or sexy, or anything depending on the creator’s intent with the character. She’s an amazing singer and her vocals do bring something different to the pool of existing singers.

2. Kagamine Rin & Len

Kagamine Rin & Len is an iconic duo in a list of Vocaloid characters as it’s unknown if they’re siblings, friends, or lovers. But that doesn’t matter as producing songs with those two has endless possibilities. Both singers have amazing harmonies when they sing together, not to mention amazing chemistry. Creators have free reign on how they interpret the duo and that is reflected heavily in the music they produce.

1. Hatsune Miku

The most iconic and popular Vocaloid, Hatsune Miku is well known throughout pop culture and is widely used by multiple Vocaloid music producers. Most people’s first taste of Vocaloid is through Hatsune Miku, more specifically through the song “World is Mine”. This character is seen everywhere, from video games to other IPs, touring in other countries, etc, pretty much making her the unofficial face of Vocaloids. Also, her voice belongs to well-known Japanese voice actress Saki Fujita, known for her roles in Boruto the Next Generation, Sword Art Online, and funnily enough, the AI robot Ritsu in Assassination Classroom.

Vocaloids are not only versatile but are also unique in their own way. From well-known voice actors to their design and backstory, each of them is loved by fans for different reasons. And while some of these characters are no longer accessible for those who are starting out, there are plenty of characters out there that are just as talented and well-designed as the ones listed above.
