Supergirl will team with Martian Manhunter to take on a strange visitor from another planet -- Mars -- on an upcoming episode of Supergirl.
"It's very emotional. It was a very emotional episode for me, just thinking about the whole idea of genocide and, you know, people being burned alive," said David Harewood, who plays J'Onn J'Onzz, the Martian Manhunter, on Supergirl during a recent interview. "I think it was around the same time as the Paris attacks. it was very emotional. The whole idea of it was weird for me to be playing, but I think it's going to be a very emotional, powerful episode because you get to see a little bit - the fans are going to be, I think, really delighted to see this because I don't think, technically, it's been able to be done before, but I think we're, thankfully, now living in an age where you get great people like Armen [V. Kevorkian] - our Visual Effects Director - who's just fantastic and he's capable of just bringing some of stuff to life and I think fans are really going to get to see a version of Martian Manhunter on the screen that they've just never, ever seen before. There's going to be something in it for the fans and something in it for just the general viewers because it's some pretty emotional stuff to cover."
CBS has officially released the episode for the January 25 episode, which also introduces Blake Jenner as the estranged son of Cat Grant.
