How Can DC Incorporate Black Lightning To The Cinematic Universe: The best way to incorporate Black Lightning, would for DC to use the story of Lex Luthor as President of the United States. In the comics, Luthor appointed Jefferson Pierce as his Secretary of Education. We can use that as the door to introduce Pierce and explore his relationship not just with Luthor but Metropolis. DC later can do a quick miniseries or one shot special showing the back-story of Black Lightning, and how he protects the city of Metropolis from the gang The 100. Lightning has enough character development, personal rogue gallery, and story for Tyrese to sink his teeth into. He is not a comedic guy, but he is a bad ass and a very intelligent one at that.
2. Steel
John Henry Irons is a weapons engineer for Amer Tek Industries. He is responsible for creating the BG-60 powerful energy cannon. When it fell into the wrong hands, he left for Metropolis and took a job as a construction worker. One day on the job at a construction site John fell off the skyscraper where he was rescued by Superman. Steel doesn't have any powers but is very skilled in technology. He has a suit of armor that not only enhances his strength but endurance as well. His signature modified hammer has the ability to hit harder than an ordinary hammer, have independent flight and has an analysis system to detect stress points of targets. Like Iron Man in Marvel, Steel has a variety of armor each with its own modification. While Steel might not have an enriching backstory as Black Lightning or other heroes on this list. He still is a solid addition to the DC Comics.
