Fan Casting Taskmaster in Hawkeye & Black Widow: On the Trail of Danger

- A guy from S.H.I.E.L.D. and a Black Widow working together. Things are getting interesting [he defends himself from a shot with his shield]. - Damn - I think we're all better than that. At least I hope you are!; Tony Masters was once a former S.H.I.E.L.D. before becoming a skilled mercenary capable of replicating physical abilities, whether combat or athletic, of anyone he observes thanks to his photographic reflexes - the result of an experimental serum, which on the other hand resulted in a sacrifice. He was now a assassin with a literal blank memory to act anywhere as long as he was paid to do so - and likewise, to be considered a problem for more than one organization.
