SeeU
A Korean Vocaloid with a futuristic aesthetic, SeeU stands out for her bright, sweet, and energetic vocals. Released as one of the few Korean-language Vocaloids, she helped broaden the software's international appeal. Despite her unique position in Vocaloid history, she never achieved the global popularity of her Japanese counterparts. Her voice excels in upbeat pop songs and emotional ballads, making her a versatile yet often overlooked singer.
Gakupo
Inspired by traditional Japanese aesthetics, Gakupo is often portrayed as a noble samurai with a humorous obsession with eggplants. Voiced by Japanese musician Gackt, his deep, mature tone gives him a vocal presence few male Vocaloids can match. Although he was once a staple of the community, his popularity has declined in recent years.
Flower
With an androgynous design and a powerful, slightly husky voice, Flowers voice was chosen with powerful rock screams in mind. Her vocals can convey both aggression and vulnerability, which led many producers to use her in emotionally intense compositions. Despite being respected within producer circles, she is often overshadowed by larger Vocaloid icons.
Oliver
Designed as a young British choirboy, Oliver possesses one of the most distinctive English voicebanks ever released. His soft, innocent tone lends itself perfectly to gothic, fantasy, and storytelling songs. While English Vocaloids have historically struggled to gain traction compared to Japanese releases, Oliver is an underrated fan favorite.
Piko
Utatane Piko's greatest strength is his remarkable vocal flexibility. Voiced by Japanese pop singer Piko, he can convincingly sing in both a masculine and feminine voice earning him the nickname “Ryouseirui” which means both voice types. Because his software was discontinued, he has become increasingly rare and receives little attention from newer fans.
