Miku Mouse is a robot that resembles both Hatsune Miku and Mickey Mouse, having the same body of Mickey Mouse, yet the appearance of the well-known teal-colored singing robot that is Miku, giving off a wacky, yet adorable vibe.

Appearance Miku Mouse is a black mouse with pale skin, sparkling teal eyes with white diamonds for pupils. and teal hair is tied in twintails held up by black and red futuristic ribbons that float in place. Miku Mouse has the same attire as the original Hatsune Miku, yet with a few differences in design. She wears a grey collared blouse with a magenta strip going down the sides, and black leather sleeves that fade out slightly and have a glowing teal streak with the wrist bands being magenta on the bottom and teal at the top, as well as a teal tie. Her gloves are different from Mickey's, looking more futuristic. Having a color scheme of black, red, grey-white and teal, acting as fingerless gloves with a teal triangle on the back. She wears black headphones that have a microphone attached on the right, and have a futuristic design as well.

Miku Mouse has a red '01' implant on the left shoulder of her sleeve. She wears a black thigh length skirt with teal trim with a pink and teal belt attached on the right of the skirt, and heeled leather thigh length boots. Just like the original Miku, the digital designs on her attire are all based on synthesizer program colours, and the bars represent actual bars within the program, as well as being based on some of YAMAHA's keyboard models. The yellow clip on her blouse reads "CHI-LOID" instead of "VOCALOID", this detail references the creator of the character, "chichimarshmallow". Her "tail", which is more likely a wire that acts like a tail, has magenta ribbons at the end. And she's noticibly slightly taller than both Mickey and Minnie (not because of her heeled boots).

Personality Miku Mouse possesses a joyous and pure demeanor, characterized by her inherent passion for singing and dancing. Notably, her persona also exhibits traits reminiscent of both Mickey and Minnie Mouse. In the vein of Mickey, she embodies kindness, resourcefulness, and a mischievous streak, often finding herself caught up in playful antics. Reflecting Minnie's essence, she exudes sweetness, nurturing care, and an elegance that is undeniably endearing. Additionally, Miku Mouse is brimming with an abundance of love and affection, which radiates from her in every interaction. She is often seen with Spring Onions or Leeks, as those are her favorite food.

Story Miku Mouse was a robot built from the ground up by a Disney and VOCALOID fan to resemble both Hatsune Miku and Mickey Mouse just for experiment, as well as being "just a joke". However, the robot mouse seemed to have people who genuinely took an active liking to her which surprised her creator. And thus they were encouraged to do more with her, upgrading Miku Mouse to become her own thing, and her own character now knowing people like the "wacky yet adorable" concept.

She was programmed by this Disney and VOCALOID fan to have the exact traits of Mickey Mouse, Minnie Mouse and Hatsune Miku all mixed together, including personality and other similarities. Soon, Miku Mouse would be provided with an actual voice, which her creator made by taking Mickey and/or Minnie's voices, and modifying them to make them sound as close to Miku as possible. Miku Mouse would soon get different versions, including, V2, V4x, and NT, which all had Mickey and/or Minnie's voice modified to fit those as well.

• Despite resembling the VOCALOID, Miku Mouse is a UTAU.
• She has her very own voice.
• It is confirmed by chichimarshmallow herself, that Miku Mouse is taller than both Mickey and Minnie Mouse, if you were to put them side by side of course.
