Origin
The second Spymaster was an apprentice of the Taskmaster who won the right to the name in a series of tests which included (but was not limited to) the killing of all other contenders. This Spymaster discovered Iron Man’s secret identity, then ambushed and nearly killed Tony Stark who was saved in time by the Black Widow. It was later revealed that Nathan Lemon was this Spymaster’s true identity, and that he had been working for The Mandarin.
