Ratt has the appearance of a machine resembling a shield with a camera lens in the middle and two supporting legs with a cannon in its back. It appears to have a structure resembling a jaw accompanied by numerous sharp fang-like teeth. This cannon turns to the opponent when it prepares to fire. Josuke notes to himself that it's an unusually mechanical Stand for a rat, and smells of oil.
Unusually for Stands, two separate rats shot on separate occasions have the same Stand.
Ratt is an especially deadly Stand not only because of its power, but also its range and the small size of its users. Only one hit is needed for the rats to defeat their opponents, while human-sized Stand users will have trouble finding and striking a nimble rat.
Ratt can fire off barbed darts which will melt anything upon impact, be it flesh or even metal.
Once hit, a large part of the body will immediately melt into organic material, a nearly impossible to heal injury that only Crazy Diamond could undo. The melted victims can then be molded into a shape such as a cube if multiple are clumped together, in which case the flesh fuses together and eventually takes a gelatinous texture. In some cases, the victims continue to live (presumably because their head is intact).
Ratt can shoot its dart up to 60 meters away, fire in bursts, and can even bounce the dart off obstacles to hit from blind spots.
