|Occupation||Molecular biologist (Metropolis University)|
|Played By||Françoise Yip|
Dr. Lia Teng was a renowned molecular biologist tenured at Metropolis University.
A North Korean doctor, she married a LuthorCorp employee in order to get a green card and work in the US. She became the head of Metron Pharmaceutical Labs that used the Lazarus serum to resurrect the dead. She conducted illegal research for Lionel Luthor.
Sometime after she left North Korea, a government agent known as the Deletion Force, deleted all records of her in the country.
She injected the Lazarus serum, a serum of blood platelets secretly made from Clark Kent's blood, to patients to bring them back to life. She treated Chad Nash and Vince Davis. Lionel threatened to scrap her project or send her back to the country where her own people would punish her for working with the Americans. Lex later blackmailed her with the specter of Federal prosecution if she didn't tell him about her research but at the same time promised to double her budget if she did so. Adam Knight killed her.
