"General Dru-Zod (d. 2013) was an Alien from the planet Krypton. As a Kryptonian, Zod had special abilities when in the star system of aYellow Sun.

The Commanding Officer in the Kryptonian Warrior Guild being in charge of the entire planet's forces, Zod rebelled against the Kryptonian Law Council of the planet to replace them with himself as ruler with the help of Faora-Ul and a battalion of loyal soldiers in a movement called the Sword of Rao. Opposed by Jor-El, Zod and his minions were captured and placed in the Phantom Zone via the Black Zero prison ship but escaped when Krypton exploded breaking the Zone's seal and made his way to Earth where he came face to face with Jor-El's only son Kal-El. Intending on terraforming the Earth into a new Krypton, Zod and his forces battled Kal-El which ended with Kal-El reluctantly having to snap Zod's neck killing him."
