Calico is a robot with a TV screen for a head, cat ears, a humanoid body, and a tail. She is in a black tank top and black miniskirt. She expresses her feelings with a yellow emoticon on the screen, her digital form. While this is her current physical form, she is actually all human media ever created, making her akin to a demigod who knows everything. Despite that, she is very lonely and hates that everyone abandons her when she's no longer useful to them, making her possessive over any friend she can get to the point of being a Yandere. While not explicitly evil, she can and will act in a threatening or panicking way if she thinks she will be alone again.
