Provided nothing changes with any of the currently running CW hero shows, that means Black Lightning will be DC hero show number five on the list.
With Black Lightning originally being developed for Fox, I wonder what plans, if any, were being discussed towards inclusion to the current CW DC fold.
That said, it’s possible Black Lightning’s alter ego Jefferson Pierce could cross paths with another hero at some point in his adventures or even make his TV debut via the event in some way.
Greg Berlanti has done a good job of establishing heroes in other CW shows prior to their debut, so I don’t think it’s crazy to assume we could see Jefferson Pierce in action before his show officially begins.
