[Phantasm]

While people often focus on Widow's combat skills, they also tend to forget that she's a master manipulator, infiltrator, and double agent. In the movies (and referenced in Agents of SHIELD), she has a lifetime's training in "becoming the mask", is able to fool a former Soviet general and Loki into divulging critical information by appearing to be in a position of weakness when she was in control the whole time, and is possibly able to defeat SHIELD/Hydra-quality lie detector tests that were designed to beat her (AoS S1 was ambiguous on that last point).

To this end, I highly recommend giving her Acting and Body Language at 16+, bolstered by a high Per score and the other skills from the Smooth Operator talent. She is as much a Face character as she is a Scrapper.

I built her with an eye towards the female Russian agent (played by Barbara Bach) in The Spy Who Loved Me (one of Roger Moore's James Bond films): able to kick ass, look good doing it, plow through mooks, fight those of her own caliber to a standstill, and manipulate everyone around her into giving up crucial information.
