Bully Fox is a character hailing originally from 4chan's /v/ videogames board from around 2022, posted sporadically onwards by various anonymous artists, either as a thumbnail to individual threads or as reaction images on existing posts. There is ongoing speculation about the origins of the character, with the most popular theory being that it is a character made by intfarm who originally created characters like Mimmi for the /int/ international board of 4chan.

She is often depicted with tan fur, countershading, brown hair, white eyebrows, dipstick ears, black pupils, a fluffy tail and varying school uniforms. Artworks fittingly sometimes feature bullying, or are formatted as reaction images related to videogame topics.

Until 11th May 2025, the character had no real official name until the most prolific unknown artist of Bully Fox made a piece of art featuring the character wearing a lanyard with the name "Robin".
