CBS' 'Supergirl' Ep 7 Spoilers: Twitter Reacts Melissa Benoist, David Harewood J'onn J'onzz!

CBS continues the freshmen season of DC Comics' Supergirl. In Episode 7, as Kara Danvers (Melissa Benoist) had her own problems to deal with Twitter had lots to say about Hank Henshaw (David Harewood)'s J'onn J'onzz aka Martian Manhunter shocker.

As we previously mentioned, Superman's cousin, Kara, has been living quietly amongst the humans. Her secrecy changes when Kara's sister, Alex (Chyler Leigh) is about to die in a horrible plane crash. After stopping the plane crash in mid-air, everyone wants to meet the new heroine, Supergirl, especially Jimmy Olson (Mehcad Brooks). As the plot to invade earth thickens, Supergirl will have to eventually face her Kryptonian aunt and mother's twin sister, Astra (Laura Benanti).

In an interview with Entertainment Weekly, Harwood explains when he knew his character was Martian Manhunter, "After the pilot was picked up, my manager told me that they were changing my character. That's as much as they'd tell me. I was intrigued by that. I didn't quite know what that meant. When I came to shoot the series, they still didn't tell me. I did the whole of Comic-Con just lying through my teeth. I didn't know what I was talking about. They told me about a week after Comic-Con. They presented me with a little Martian Manhunter doll and several comic books of Martian Manhunter. I went home and devoured them. I thought they were just fantastic. I was delighted."

Check out what Twitter had to say:

@Darth_Flores tweets, "I'm late to the party but the fact that Martian manhunter is on supergirl is f*cking amazing"

@MiWalkedDa adds, "Well there's Arrow, Flash and Hawkgirl, then there's Supergirl and Martian Manhunter plus all the other heroes"

@queensarcasm writes, "Martian Freaking Manhunter. MARTIAN MANHUNTER. I am so excited now. Sucks to be those people who wouldn't give #Supergirl a chance."

@thepeevishbones states, "MARTIAN MANHUNTER MY FAVORITE DC CHARACTER IN SUPERGIRL! WAY TO GO DC TV!"

@JesseManderson mentions, "We now live in a world where Martian Manhunter is on a tv show. Holy sh*t this is glorious. #supergirl #jonnjonzz"

@UpulTR loved the introduction, "And the Martian Manhunter turns up on #Supergirl. What an entrance it was too. Happy"
