Biography
Doctor Teng was a brilliant Chinese scientist. American businessman Lex Luthor engineered Teng's escape from mainland China and brought him to the U.S. so he could work on a special project for LexCorp - namely, cloning Superman. Teng worked on Luthor's project and came close to succeeding. However, there were unexpected side-effects to the cloning project, resulting in a bizarre monstrous mockery of Superman.
