Taskmaster is a Marvel supervillain who possesses the power to copy any fighting style or move that he observes. He is an extremely skilled fighter, capable with virtually any weapon known to man. He most often carries a sword, shield, and bow and arrows, but also carries knives, guns, and many other weapons.
After he masters a fighting style, he sells it, teaching it to anyone for the right price. He most often gets his "merchandise" by watching videos of combatants, and copies them photogenically. He cannot however, perform skills that require superhuman abilities, such as lifting a car or firing energy blasts. If he watches a fighting video in fast-motion, he can copy it at the same speed, granting him semi-superspeed in that instance.
Taskmaster is a frequent opponent of Captain America, as well as the anti-hero mercenary, Deadpool, who is the only one whose fighting maneuvers Taskmaster cannot replicate, due to his unpredictability.
Taskmaster was featured prominently in UDON Studio's run of him, where he obtained a new costume and powerset as well as a new standard weapon set, including replacing his sword with a katana, his bow with guns, and his shield with an energy weapon generator. UDON's run was also the first time he used "Tony" as a name although, at the time it was an alias. During UDON's Agency X series, Taskmaster was a main character of the team. During this time, he became a reluctant friend of Deadpool after starting to date Deadpool's secretary, Sandi Brandenburg. After the Agency X run of Taskmaster, UDON didn't work on his character anymore, and as such his new costume and powers were abandoned outside of noncanon appearances.
Taskmaster appears as a recurring villain on the animated series Ultimate Spider-Man. He serves as the main antagonist in the first half of Season 3.
