Marvel supervillain - Taskmaster

(black widow villain)

Wikipedia:
Taskmaster is a mysterious figure believed to have been born in Bronx, New York City. He has the ability to mimic the physical movements of anyone he witnesses; writers differ on whether this counts as a "super power". He claims that he has had this ability since childhood. He works as a combat instructor and trains others to become lackeys for other villains by utilizing the techniques he has learned from his observation of superheroes and participates in mercenary jobs from time to time. Initially portrayed as a villain, he has also been shown training U.S. Agent and other neophyte superheroes at the behest of the US government. As a mercenary, he has no ideology except that of his employer. Due to his ability to imitate the techniques and armory of other heroes and villains, Taskmaster has occasionally been used to impersonate other characters.
