was casting a transgender character to appear in season four, today\'s Comic Con International panel at San Diego introduced fans to Nia Nal, a transgender superhero known as Dreamer who will be played by Nicole Maines.

According to her official character description, Nal is 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).

The Dreamer becomes the first transgender superhero on TV, played by

Nura Nal, the Legion of Super-Heroes member known as Dreamer in the comics, was an alien with precognitive abilities. The character was created in 1996 by Tom Peyer, Tom McGraw, and Lee Moder.

She may be positioned to take over the newsroom, as she comes in with a strong journalism background a la Snapper Carr and the initial casting breakdown back in May described her as a “young Cat Grant type.”

In-story, Cat Grant left the news industry to work in government, serving as press secretary to President Olivia Marsdin.

At the same time, Lena Luthor has purchased the company, tying CatCo\'s handful of stories to Supergirl/DEO tales almost by default. While James Olsen still nominally runs the company, he has rarely been seen there and Winn Schott left CatCo altogether to go to work for the DEO. Adding a new, recurring character based out of the company likely indicates that CatCo will play a bigger role next season.
