Agent ZX-5 was one of the top US spies. He answered to his superior Major Jason, who gave ZX-5 missions around the world fighting the Axis powers during WWII. He would continually come into conflict with foreign spies such as Madame Terror. After the war, he goes on to become a private eye.

He was known for his charm and carried a trick cane with numerous buttons each with a different function such as one for tear gas.
