"Fitbot User" is a female human character created and owned by the artist kawaiidebu.

A Trekkie with a bad influence on machines, the user bought Fitbot 1.0 (an android fitness instructor) under the pretense of physical training, only for her to indulge in cravings so much that Fitbot gave in and the two packed on the kilograms together. After making her new Fitbot friend a fatty, she was assigned another Fitbot to get back into shape... but so far, she has only given another robot a fat fetish.
