That's the question posed to Black Lightning (Cress Williams) in this trailer that's a mish-mash of The CW's Arrowverse of DC superhero shows, as well as its newest, Black Lightning, which is coming in 2018.
Black Lightning follows Jefferson Pierce, a mild-mannered father of two girls and the principal of a charter high school in a rough New Orleans neighborhood. But that's not always who he was. Years ago, he was Black Lightning, a superhero with the power to control electricity, which he used to keep his community safe. He gave it up for the family life about a decade ago. But now, with the growing threat of gang violence in the neighborhood, he's suiting up again to protect his family and his community once again.
