When the Goblin Prince Galar entered an alliance with the Kingdom of Arcadia, Clench, the chief engineer, was assigned to work with the Minister of Technology, Ayame. Combining their knowledge the two developed the Mech Armor, and later the Mech Rider calvary troop. However, with the final defeat of the great Kingdom Clench lost not only his working partner, but his vast fundings, leaving his secret weapon incomplete.

When the Nerubians, who replaced Arcadia in the power vacuum, could not offer a consistent flow of cash, Prince Galar decided to sell his services elsewhere. Clench dreamed of completing his ultimate war machine, and was eventually approached by the Dragon Slayers. The Emissary offered Clench the ability to complete the ultimate golem, Gorbash, in return for his services. Clench readily agreed, his overriding drive to complete Gorbash overcoming common sense.
