On Krypton, Tor-An grew to become a fierce soldier in the Kryptonian military. He became a loyal servant of General Zod and under him, helped to stage a coup d'état of the Council of Krypton. Tor-An was present when General Zod raided the Legislation Chamber, and escorted Jor-El out on Zod's orders. However, Jor-El managed to overpower Tor-An and use his firearm to kill two other soldiers before knocking him unconscious.
Later, he was arrested alongside General Zod and the rest of the Sword of Rao for their crimes, sentenced to 300 cycles of somatic reconditioning within the Phantom Zone. After the destruction of Krypton's core released the shock wave that freed him and the other prisoners from the Phantom Zone, he joined General Zod again in his quest to search for other surviving Kryptonians.
Search for the Codex
After Zod delivered his ultimatum to the humans of Earth, Tor-An delivered the General and his forces to Smallville, Kansas in order to acquire the Codex from the home of Superman. Tor-An returned to attack Superman after he'd damaged General Zod's Breather before returning to the Black Zero. He later retrieved Nam-Ek and Faora from Smallville after they encountered Superman, dragging their brawl to a nearby town.
Following Colonel Nathan Hardy's activation of the Phantom Drive aboard Kal-El's infant pod, Tor-An was pulled into the Phantom Zone singularity above Metropolis, along with the remaining Sword of Rao, Colonel Hardy, and Dr. Emil Hamilton.
Genetically engineered into the Kryptonian Warrior Guild as a warrior, Tor-An was known as a cold-blooded killer without a drop of mercy or compassion in his veins, as he was genetically incapable of feeling empathy towards his enemies. As a result, Tor-An was the favorite hatchet man of General Zod, being quick to get his hands dirty when the cause required it.
His greatest weakness came from him having been programmed with limited thinking boundaries engineered into his genetics. As a result, Tor-An possessed a poor grasp at free will and was prone to dogmatic tunnel vision, utterly unable to live out any lifestyle other than the one that he was born for.
