CBS recently released the first pictures of actress Melissa Benoist outfitted in the new Supergirl costume.The new CBS superhero television show, Supergirl, stars Melissa Benoist (who is best known as Marley Rose in the hit teen comedy Glee) as the last female survivor of the doomed planet Krypton. This alien survivor is named Kara Zor-El, and is the cousin of the rather famous male Kryptonian survivor, Kal-El, better known as Superman. In the comic books from which the Superman/Supergirl mythology derives, Kara is older than Kal, but due to the whole time/space continuum thing and the differences in how their individual Kryptonian rockets reached Earth, when Kara lands on this planet, Kal has been here for over thirty years, and in the comics, Kara is still a teen. Benoist, though 26 years old as of her costumed debut, can pass for a mature-looking teen girl. Fans have generally shown approval for the new Supergirl costume, which was designed by Coleen Atwood, a three-time Oscar winner for costuming. The superhero costumes in the TV shows Arrow and Flash, were also designed by Atwood. As DC Comics, the publisher of the Superman family of books, has rebooted their superhero universe a few times, the question of when Supergirl first appeared is a bit convoluted. Supergirl's first actual appearance was in Action Comics #252 (1959). That is considered to be part of DC's Silver Age of Comics. DC rebooted their universe in the 1980s, effectively creating a new continuity, which is often referred to as the Modern Age or Copper Age . Supergirl's first Modern Age appearance was in the comic book titled Superman/Batman #8 (2004). The new CBS Supergirl television show starring Melissa Beniost will premiere at some point in the 2015-2016 tv season.
