Although Black Flash will be re-introduced as a villain in Season 3 of “The Flash,” executive producer Aaron Helbing revealed that the returning baddie will actually help Barry (Grant Gustin) save Iris (Candice Patton) from her potential death at the hands of Savitar.

“The thing about the Black Flash is he has the ability to essentially kill the Flash, in that he sucks all his energy and life force, the way the Time Wraith did,” Helbing told TV Guide. “He's going to be a formidable adversary for Barry, but he’s also going to teach Barry a lesson and that’s going to help Barry realize what he needs to do to save Iris.”

Black Flash’s return to CW’s DC TV universe was revealed by executive producer Andrew Kreisberg at the Television Critics Association’s press tour earlier this month. But this time, the character won’t just be appearing on “The Flash.” “You might be seeing him on multiple shows,” Entertainment Weekly quoted Kreisberg as saying.

Hunter Zolomon, a.k.a. Zoom, was transformed into the Black Flash by Time Wraiths after Barry defeated him in the Season 2 finale. Although he was carted off to parts unknown at the end of the episode, he is set to come back to wreak more havoc.

“[Black Flash is] a classic character, and we have storylines on several shows that fit having him return,” Kreisberg added (via Collider). “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, and how do you stop the devil? So it presents an interesting challenge for the heroes of the respective shows in which he appears.”

When asked if Sears will reprise his role, Kreisberg said: “I’m not sure. Teddy is pretty busy with [‘24: Legacy’].”

“The Flash” winter premiere (Season 3, episode 10) airs on Tuesday, Jan. 24 at 8 p.m. EST on The CW.
