After you've watched the first episode you'll see there is no reason to spoiler that.ah, the first episode is out. yeah, I was just talking about the trailer. and, yes, I even overlooked them more or less in the trailer. it focused on him and *his* powers.
The girls have powers too. in comics, they are more used and relevant then Black lightning himself these days. he mostly shows up as retired superdad. Kindof like Steel and Natasha Irons. Natasha is way way more active then him in comics.
