Personality
Roboco is a robot girl who loves to pose. She has a killer instinct inside her. She is great at shooting except in video games, but likes to run over people in them. She hates when games try to surprise her. Her voice is spoken very calmly, almost a whisper.
Appearance
Roboco wears a biker jacket with red stripes. She also wears black rimmed glasses. Her lower body consists of a pair of inverted chaps that only cover her crotch. She also has a pink hoodie which sleeves have a camouflage pattern and small white paw prints.
Her hairstyle is often "modified" between short brown-hair or long-hair ending in a tinge of pink highlights, sometimes with cat ears or wearing glasses. It is revealed that, in the Holo no Graffiti shorts, she ties her hair in a ponytail.
Starting with her her 4th fes idol costume in 2023, Roboco's robotic arms were toned down, originally being mechanical from her shoulders to her hands, now they resemble normal arms and only her hands remain robotic, looking like gloves.
Background
Roboco was originally a character created and modeled by kuromaru9 with some artwork dating back to 2014, years before the VTuber trend started.
Roboco's first 3D model was finished on 23 May 2016. Clips of the model appeared on the artist's YouTube channel the following month.
Her channel was created on 7 February 2018, her Twitter account was also created on February, her first video was uploaded on 4 March 2018.
