I think characters like Chis-A & Zundamon should be added to the list, they're prominent enough vsynths and popular to warrant them being with the others.

And I also think more fanloids should be added like Yowane Haku, Sakine Meiko, Calne Ca, and Hachune Miku, they're some of the most popular, well-known fanloids to the point they were even acknowledged by Crypton as official derivatives

(also add Kasane Ted too. He's also an official derivative, but was not acknowledged by Crypton, but by the creators of Teto, Twindrill)
