Also known as: 初音ミクオ, ミクオ, クオミク
A fanmade Vocaloid that is the genderswapped male version of Hatsune Miku. Not much is known about Mikuo except that he inherits some of Miku's fanon traits, especially those regarding Spring Onions. His voice is a masculinized version of Miku's voice samples.
Mikuo is often depicted as Miku's bigger brother rather than as her twin. He is often illustrated with a body build like Kaito (Vocaloid)'s, but a build similar to Len is not uncommon. He is said to be buddies with fellow derivatives Akaito and Meito (Vocaloid).
