Chief Admiral Cronk and Lieutenant Commander Zephyr were a duo of robots from the world of Ratchet and Clank that first met the two when they were trying to defeat Emperor Tachyon and find the secrets of Ratchet's race. The two had worked and lived with Talwyn Apogee in the Apogee Space Station as her caretakers and helped her, Ratchet, and Clank with various adventures. They had several fights with each other, and were often very dim-witted and had Southern accents. However, they tragically died when transferring the evil space witch Vendra Prog after her brother rescued her and blew up the ship they were transferring her with them in it.
