In the mirror universe, Doctor Arik Soong was a Terran scientist, born circa the year 2100. Prior to 2155, he served as Imperial Advisor on Technology to the Terran Emperor. Following the coup which brought Empress Sato I to power in January of that year, he was one of the few members of Cochrane's inner circle who was not executed by the new Empress as she could find no other Terran who could match his genius. In this position, he was charged with studying and reverse-engineering the futuristic technology that made up the USS Defiant.
While engaged in this task, Soong was approached by Sato's husband, Thy'lek Shran, who convinced the computer expert to reconstruct the Defiant's eradicated historical database. While unable to fully restore the database, Soong was able recover enough to reveal that Sato had lied about the origin of the Defiant, which had come from the future of a parallel universe, rather than from their own. With this information, Shran was able to move against Sato, but not before again imposing on Soong's scientific knowledge to create a binary clone from Shran and Sato's DNA.
After Sato escaped from exile and rebel imprisonment and returned to Earth to reclaim her throne, she personally executed Soong by vaporising him with a 23rd century phaser from the Defiant. (ENT - Mirror Universe novel: Age of the Empress)
More than 200 years after his death, Soong's work with artificial lifeforms was carried on by his great-grandson Noonien Soong. However, the younger Soong, who was in the employ of the Klingon-Cardassian Alliance, was never able to fulfill his dream and create a fully functional android as the Alliance would not permit him to do so.
