Another extra-ordinary human being, by the name of Sgt. Bette Sans Souci aka "Plastique" -- is on her way to meet with The Flash.
Here are some early details about the character:
The series’ incarnation of the metahuman is a fetching young redhead who was a bomb specialist with the Army before she was injured by an IED in Iraq. Since being exposed to the Central City explosion, she can turn any object into a bomb with just a touch of her hand.
