The Persuader was an item which Ratchet and Clank could trade for Raritanium with Fred, a gadget engineer they met at the Blarg Station and whom they encountered again in the sewers of planet Pokitaru. It allowed the user to obtain weapon-cost discounts at Gadgetron vendors. Its original purpose was to control minds, but it failed to do so and it only worked on Gadgetron vendors.
