The Repo Girls primarily deal in disposing of older robots and their obsolete fuel. This fuel, IS-13, is flammable and becomes increasingly poisonous with age, and can disable a modern robot's circuitry. The Repo Girls provide an off-the-books, cheaper alternative to safe and legal chemical disposal. They have been known to simply dump old fuel canisters, raw fuel, and outdated robotics in nature and abandoned places. They have little regard for nature, and only work with the widest profit margin in mind.
