It was first seen on Clank's homeworld of Quartu, where a scientist was tricked into creating it in order to produce Drek's Ultra-Mech Unlimiteds. After knowing this, he planned to destroy it. He allowed Clank and Ratchet to use it, that way Clank could become a huge mech and sabotage the other mechs. After the mechs were destroyed, instead of destroying the machine, the scientist decided to program all existing machines to enlarge only Clank. Several more Ultra-Mech pads were used again in later games.
