Fan Casting Taskmaster / Fenris / Swordsmaster in Marvel Cinematic Universe

Anton Dreykov was abandoned by his father when he was young, as General Dreykov was only interested in having a daughter. As Anton grew up, he honed his photographic reflexes with constant training. He interrogated Red Room associates and learned many things about his father, growing to hate him. Then he learned about the explosion that injured his sister, Antonia Dreykov, and later found out about that his father made her a cyborg assassin and used his chemical mind control on her. He would later plan to avenge his sister, but found out from Yelena Belova that she killed Dreykov and that his sister is safe and tells him where she is. He stays in touch and visits her and the Widows often.
