The Supergirl panel is up and going at Comic-Con right now and we have a reporter on site sending in the hightlights.
The big theme for the new season will be what it means to be human. J'onn J'onzz is going to find out that he's not the last Green Martian and we'll be introduced to his father played by Carl Lumbly who was the voice of J'onn J'onzz in the Justice League Animated Series.
Adrian Pasdar from Heroes and Agents of SHIELD will be playing the character Morgan Edge. Yael Grobglas (Jane the Virgin, Reign) portrays DC character Psi, a psychic villain who uses people's own minds against them. Psi's agenda puts her on Supergirl's radar, and their meeting will affect the Girl of Steel in surprising ways. Emma Tremblay (Elysium, The Judge, The Giver, Wayward Pines) plays Ruby, a smart, independently minded National City kid who's fascinated by Supergirl and ends up in jeopardy because of it.
The new season will see more of Cat Grant while Jimmy Olsen will go back to being a journalist and get a love interest. Mehcad Brooks is looking forward to both the love interest and playing the Guardian more.
Lyra and Wynn are still going strong as the season beings. And Mon-El will be back those his exact role for the season will be a mystery.
Melissa Benoist said there may be some tweaks to the costume but Andrew Kreisberg claims spoilers.
Katie McGrath is a series regular now and is looking forward to making the character of Lena Luthor her own.
Benoist says she was surprised that they wrote in the Superman vs Supergirl fight.
There are no plan for Superman to appear at the moment, but if Tyler Hoechlin's and the shows schedule permits he could return.
