The Flash Kelly Frye has signed on to play DC Comics character Plastique in the upcoming "The Flash" TV series on The CW. In the series she'll play a more heroic incarnation of the character, at least initially. Plastique (aka Sgt. Bette Sans Souci) was a bomb disposal expert in Iraq. Following the accident that gave Barry Allen (Grant Gustin) his super speed powers, Bette finds herself with the ability to turn everything she touches into a bomb.
