Rat

Rats are a humanoid faction appearing in Borderlands 2. Whereas Bandits inhabit the wastes of Pandora the Rats occupy the urban or urban ruins of the planet. Ostensibly under the direction of the Sheriff, Rats patrol and raid to keep her entertained.

Very much like actual rats, this faction will grab and make off with loot. This may lead to interesting decision points as a player weighs the benefits of defeating a threat or pursuing a rat which has acquired a valuable loot item. Defeating a hoarding rat will result in a pinata effect as seen in Crawmerax the Invincible.
