Mikuo Hatsune (初音ミクオ)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 & 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.
