In a post on Instagram, Williams shared a report from FandomWire earlier in the week stating Black Lightning would appear in "Crisis on Infinite Earths." He wrote, "You asked for it...you got it!!! #blacklightning #crisisoninfiniteearths #getlit."
First premiering in 2018, Black Lightning is based off the DC Comics character of the same name. The show has aired two seasons so far, though it's remained separate from the Arrowverse thus far, with the show not actually being part of the shared DC TV Universe. It's unclear what this might mean for the show and it's connection to other heroes going forward. The news has not, at this time, been confirmed by The CW, and the extent of Black Lightning's involvement is not known.
Williams will be one of many heroes in the upcoming Arrowverse crossover. The event will also see Brandon Routh, who plays Ray Palmer/The Atom on DC's Legends of Tomorrow, play Kingdom Come Superman. The event will also feature Burt Ward, who played Robin in the '60s Batman television show, in an undisclosed role.
Slated to begin in Fall 2019 on The CW, "Crisis on Infinite Earths" currently has no announced air date. However, the event will span five hours, with Arrow, The Flash, Supergirl, Legends of Tomorrow and Batwoman all participating. "Crisis on Infinite Earths" will seemingly be split around the winter hiatus.
