During Krypton's last days, General Dru-Zod lost faith in the Council and their decision making. Jor-El had an audience with the Council telling them that Krypton would implode in a matter of days. Lor-Em and High Eminence Ro-Zar, however, inform him that evacuation is inconsiderable.
The audience is suddenly interrupted by General Zod and his radical Sword of Rao loyalists, who shoot their way into the chamber, with Zod personally killing High Eminence Ro-Zar, while Lor-Em and the other councilmen were forced from their thrones by Faora-Ul.
However, after the Sapphire Guards undermine the coup and capture General Zod and his loyalists, they also free Lor-Em and the councilmen. The council then promptly re-assembles, with Lor-Em now replacing Ro-Zar's position as High Eminence. He proceeds to put the Sword of Rao on trial, which incidentally included Dev-Em II, a family member, sentencing them to 300 years of somatic reconditioning within the Phantom Zone, much to General Zod's dismay. Lor-Em and the rest of the council then proceed to watch as the war criminals are encased in cryocapsules, loaded onto the Black Zero starship, and put through the Phantom Zone Projector.
Lor-Em was survived by Dev-Em II, the only known family member to have survived the catastrophe, as he was placed into the Black Zero starship along with the rest of the Sword of Rao.
Genetically engineered to be a skilled leader (ultimately becoming the High Eminence of the Kryptonian Law Council), Lor-Em was fiercely loyal to Krypton's ideals, much to the chagrin of Jor-El and General Dru-Zod, with the former seeing Lor-Em's ideals as stale, flawed, and outdated, and the latter seeing Lor-Em representing a "degenerative bloodline" that lead their native planet to ruin.
Lor-Em was also quite dogmatic, refusing to take Jor-El's warning of Krypton's imminent destruction seriously, and thus also refusing to assemble an evacuation, which was ultimately his undoing, causing him to perish with his native planet.
Powers and abilities
- Kryptonian physiology: As a Kryptonian, Lor-Em's bone structure is almost identical to that of a human. On a planet near a red class M main-sequence star, like his native Krypton with its sun Rao, Lor-Em had physical attributes nearly identical to those of humans. However, if he were to travel to a planet near a yellow G-type main-sequence star, like Earth, he would have gained many incredible superpowers, identical to those of Superman, which would have made Lor-Em also appear godlike.
- Limited free will: Lor-Em's greatest psychological weakness comes from him having been genetically engineered in a Genesis Chamber, with thinking boundaries programmed into his engineered DNA. Indeed, Lor-Em was even more debilitated by this than General Zod, as it induced him to have a poor grasp at free will, and a tendency for dogmatic tunnel vision, leading to Lor-Em being unable to see just how ineffective his Kryptonian Law Council was. Indeed, Lor-Em was so incapable of living out any lifestyle other than the one that he was born for, that he doomed Krypton with his refusal to take Jor-El's warning seriously and to assemble a planetary evacuation.
