Any further official biographical information by the creator is unknown. However, this concept is all but forgotten in Japan, whereas in the overseas community, her popular redesign is treated as a risque Miku, still evil, but in a rather different way. She was presented with a gray skin color and looked menacing. Zatsune Miku, in Japan, used to be a parody character as an evil Miku or an anti-Miku attacker android.

At the end of the PV, it appears Hatsune has been over taken by Zatsune's influence.

However, Hatsune is prepared, along with her friends Hachune and Lulu. In the PV Zatsune manifests and appears to be ready to fight Hatsune. She made her appearance in the upload "Hatsune Miku 3D, First appearance!!", which features Hatsune Miku in 3D mouthing one of her popular songs. As a fanmade character, she has no direct personality much like the original Vocaloids it is purely up to any fans. The personality of Zatsune Miku has not been elaborated on particularly, but she is often depicted as dark or evil. She surprisingly does not have that much r-18 art with her more risque design. This designs continues to be the most popularized, meaning there is very few artworks that exist portraying Zatsune's initial design. Her skirt is black and she's often is drawn with long boots or thigh highs when wearing heeled shoes.

Zatsune's appearance gradually became very similar to the original Miku's and while it still holds the black and red theme, it changed from artist to artist which resulted in the current design having a puff sleeved top with a cleavage window and a split to show her navel. On her upper left arm is the infinity symbol. Her arm warmers, headphones, and futuristic ribbons are black and red. Under her skirt there appears to be red bloomers over black bike shorts, while her skirt is light gray with black trim and so are her thigh highs, followed by black slip on shoes. The symbol parodies the heartless emblem from the video game series Kingdom Hearts.

She wears a dark top with a key-shaped black heart outlined in red. The design by Japanese CG artist aloha, is a female character similar to Hatsune Miku though her eyes are white and her hair is dark gray, her skin is metallic gray depending on her presented form, her fingernails are painted in red and floating above her arm is a spring onion.
