Sargon cut the diamond in two and hit a high-voltage generator hidden under the diamond by Voltini. Voltini and his gang took Sargon and Morevilt hostage and he threatened to kill Morevilt unless Sargon split the diamond halves into smaller, salable gems. Sargon obeyed, and then commanded the small gems to free Morevelt. He turned one diamond into a wooden shield to deflect Voltini’s volt gun, and defeated the villain.
