Melissa Benoist, Mehcad Brooks, & Chyler Leigh Bring 'Supergirl' to Comic-Con!

Mehcad Brooks, Chyler Leigh, and Melissa Benoist speak on stage at 2018 Comic-Con!

The Supergirl co-stars addressed the crowd at the Supergirl Special Video Presentation and Q&A at the event held at San Diego Convention Center on Saturday (July 21) in San Diego, Calif.

They were joined by their other co-stars Katie McGrath, David Harewood, and Jesse Rath.

At the event, it was announced that Supergirl will be adding three new cast members – April Parker Jones as series regular Colonel Haley, David Ajala in the recurring role of Manchester Black, and transgender activist and actress Nicole Maines, marking the first transgender superhero on TV. She made a surprise appearance during the panel!

Nicole will play Nia Nal, aka Dreamer, “the newest addition to the CatCo reporting team. A soulful young transgender woman with a fierce drive to protect others, Nia’s journey this season means fulfilling her destiny as the superhero Dreamer (much like Kara came into her own as Supergirl),” Deadline reports.

Season four of Supergirl will premiere on October 14 on The CW!

FYI: Melissa is wearing Zimmermann.
