SUPERGIRL: Come Get Your First Look At David Harewood As *SPOILER*

Talk about misdirection.

For months now, fans have been under the assumption that David Harewood was playing Hank Henshaw a.k.a. Cyborg Superman, but tonight's episode of Supergirl revealed (and as you can see above) that his role was the polar opposite.

Harewood is actually playing J'onn J'onzz a.k.a. the Martian Manhunter! 

Executive producer Andrew Kreisberg admitted that adding an original member of the Justice League to the series was not a decision the creative team took lightly, but at the end of the day, they felt it was the right call to make. “Within the body of the Supergirl series, there is a Martian Manhunter series rolling throughout, it fit in with how Supergirl has been evolving. She’s embraced her powers and stepped out into the light, and in a way, J’onn is closeted and afraid. He’s one of the most frightening-looking Justice Leaguers, but he has the purest heart.”

Harewood shared that we'll learn a lot more about his character's past in episode 11 and that it will be one of the series' most powerful episodes to date: "It was a very emotional episode, just thinking about the whole idea of genocide and people being burned alive. It’s going to be a very emotional and powerful episode, and fans will be really delighted to see it.” He also adds how J'onzz, after losing his own children, views Kara & Alex as surrogate daughters and cares for them a lot more than he's let on: "Having lost his own children, [Jonn’s] got a lot of pain and melancholy, which is fantastic to play. These two girls represent something that’s very close to him.”

Check out what Harewood, who plays J'onzz, Chyler Leigh, who plays Alex Danvers, & Kreisberg had to say about the huge reveal in the video interviews below:
