Detecting the scout ship, Zod travels to Earth where he demands that Kal-El surrender to him, or humanity will suffer the consequences. Clark agrees to surrender to the U.S. military, who hand Lois and Clark over to Zod's second-in-command, Faora. Zod reveals that he intends to use a terraforming "world engine" to transform Earth into a Krypton-like planet, to eradicate the human population, and to use the codex to repopulate the planet with genetically-engineered Kryptonians. After Clark and Lois escape the ship, Clark defeats Faora and another of Zod's henchmen in Smallville, convincing the military that he is on their side. Zod deploys the world engine and initiates the terraforming in Metropolis and over the Indian Ocean.
