VIDEO : 'Supergirl' Casts First Transgender Superhero

TV is getting its first transgender superhero.
Channel24 reports Nicole Maines will star in The CW/Warner Bros.? **Supergirl** as Nia Nal.
Producers describe the character as a ?young transgender woman with a fierce drive to protect others.?
Maines is a transgender activist who won a discrimination lawsuit against her school.
She sued the school for forcing her to use the staff restroom.
Maine?s highest court ruled in 2014 that school officials violated state anti-discrimination laws.
