Arrowverse executive producer Andrew Kreisberg revealed more details about Black Flash's return during the 2017 winter TV Critics Association press tour. He promised that Black Flash will be back on "multiple shows," but didn't clarify which specifically.It's unclear if Teddy Sears will reprise the role considering his character Hunter Zolomon turned into Black Flash in the Season 2 finale . Kreisberg said Black Flash will have "sort of classic comic book Grim Reaper aspect, it's just it will be on multiple shows.""He's a classic character. We have storylines on a couple of the shows that fit having him return," said Kreisberg. "There's something so scary about him, even sort of scarier than when he was just a man, because now it's like he is the Grim Reaper, he is the devil, so how do you stop the devil? So it presents an interesting challenge for the heroes of the respective shows in which he appears."As for what's next when The Flash returns, Kreisberg previewed that Barry and The Flash team will find out "a little bit more about the future" and Iris's foretold death so "they now have a list of things they know will occur between now and May.""Their operating principal is can they stop enough of these things to change time. They have a little bit of a roadmap," said Kreisberg. "They've got a mission of the week to see if they can change the future. ... They've never had to deal with knowing something terrible is coming down the pike and can they avert it."Meanwhile on Supergirl, Kara's top priority is still facing Cadmus and unraveling the mystery of Mon-El."I think a lot of the pull of the next episodes is the mystery of Mon-El and what is he hiding and who are these people who are tracking him? That coincides with the two of them becoming closer and seeing where that relationship goes," said Kreisberg, adding, "There are going to be a couple other returning villains: Livewire is coming back, Parasite is coming back and she's going to be face off against Mr. Mytzlplk [who will be played by Once Upon a Time in Wonderland alum Peter Gadiot]."For more from The CW's TCA press day, Greg Berlanti talked about plans to bring back Superman Music Meister was confirmed to be the Flash/Supergirl crossover villain and all four of the Arrowverse shows were renewed
