Genderbent Vocaloids

Genderbent Vocaloids are Vocaloids with the gender switched. This is very common among American fandom. Usually Genderbent Vocaloids are actually Vocaloid songs pitch-changed to create a male or female song; they are rarely songs made with a different voice configuration. Kairu (AKA: narutofreek123) has made a tutorial for people to make Genderbent songs correctly

Mikuo Hatsune (初音ミクオ Hatsune Mikuo) is Miku's genderbend. Personality-wise, he has no differences from Miku besides the fact that he is male, and that he carries a masculine and lower pitch of Miku's voice. He wears black trousers instead of Miku's skirt. His hair is usually loose and short, though some users draw him with two pigtails in the same manner as Miku's. Mikuo is drawn either in the same body size as Miku herself (in the same style as Rin &amp; Len) or much older and bigger, with about the body size of Kaito. Sometimes he is seen as Miku's older brother, although this is rare. Here is a video featuring him.

Kaiko (カイコ Kaiko) is Kaito's genderbend (sometimes his sister, presumably the youngest in their family), using an octave (sometimes two) higher than Kaito. She is almost a female replica of Kaito. Two designs of Kaiko exists; one is the original Kaiko inspired from the anime and game Idolmaster (complete with a diagram), while the other one is a variant of Kaito's clothes. Kaiko sometimes uses her brother's assumed surname, Shion, Also Kaiko's voice is higher than the others. Example here
