X2 was a Japanese spy who attempted to contaminate American blood banks with leprosy during World War II. He was stopped by Dr. Nemesis.

X2 was very athletic and a skilled fighter. He was aided by slaves who he had infected with leprosy. Although he used a whip on his slaves, he generally didn't carry any weapons, except a syringe to infect people.
