It and its companion were made into Stand users by Akira Otoishi. While it has no evil intent, the rat has a natural instinct to eat and goes after even humans as a food source. Thus Jotaro Kujo and Josuke Higashikata hunt him down before it can procreate and make a swarm of rat Stand users.
Bug-Eaten is a brown rat approximately 20 cm long. It possesses a strange protuberance on the forehead as well as an abnormally large nose. Its right ear has been chewed out in a fight, earning it its nickname.

Ratt is a rifle like Stand enabling Bug-Eaten to shoot corrosive darts which can melt anything they touch.
Believing that only one rat exists, Jotaro and Josuke go hunting for it for damage control after Jotaro questions the defeated Akira. In the process, the two rats had managed to meld together the bodies of other rats into cubes of flesh.
Diamond Is Unbreakable
Jotaro and Josuke follow a drain pipe to an empty house and discover a rat in the kitchen in the process of testing its Stand ability on humans. Josuke quickly disposes of it, but is surprised by the presence of the second rat, whom Jotaro names Bug-Eaten. After moving their battle outside, a deadlock commences with both sides refusing to move from their cover. Bug-Eaten is eventually shot and killed when Josuke tricks the rat from moving from its cover.
