7. Dottie Underwood (Agent Carter)
Bridget Regan’s Dottie Underwood was a surprisingly great addition to the MCU, turning up in Agent Carter as an unsuspecting new resident at the Griffith Hotel before revealing herself as a psychotic Russian agent of the evil organisation Leviathan. Her evil ‘debut’, killing Otto Mink was one of the highlights of the first season and from there she went on to become the perfect nemesis for Peggy Carter herself.
What is even more intriguing is that she helms from the same Red Room that Natasha Romanoff / Black Widow; from her chilling flashback killing her fellow student without question to her deadly actions late in season one of Agent Carter, she has proven herself to be great nemesis, and we eagerly await her return in season two.
