Executive producer Andrew Kreisberg announced during the Television Critics Association’s press tour that The Black Flash will be making his return to The Flash and he might be appearing on multiple shows.
The Black Flash appeared in the season two finale after Hunter Zolomon (Teddy Sears) was transformed into the Black Flash by the Time Wraiths. The comic book version is basically a Grim Reaper for speedsters, sending them back to Speed Force upon their death. While technically a villain, Black Flash is more of a personification of Death than a mustache-twirling antagonist.
“He will [be] the classic comic book Grim Reaper aspect,” Kreisberg says. “It’s just going to be on multiple shows. He’s a classic character and we have storylines on multiple shows that fit having him return. There’s something so scary about him, even scarier than when he was just a man because now he is the Grim Reaper, he is like the Devil. How do you stop the Devil? It presents an interesting challenge for the heroes of the respective shows in which he appears.”
As for Sears returning to reprise his role. “I’m not sure,” Kreisberg said. “Teddy is pretty busy with [24: Legacy].”
