Not that long ago Cartoon Network introduced a block called DC Nation containing a number of new shows created by the famous comic book company, among the block we saw a number of shorts from different names from within the DC Universe but the one short which caught everyone's eyes is Amethyst Princess of Gemworld, which existed as an 80s comic series.
In this version, a geek teenage girl named Amy Winston gets sucked into the video game she's playing and is transformed into Princess Amethyst through the power of Anime Magical Girl shows.

The geek part is worth noting, as far as I know this is the first ever geek girl in western animation to become the lead in a magical action girls cartoon, with many of her predecessors being either too pink, too girly or Sabrina the Teenage Witch. To use an anime example, Amethyst is like Cecily Campbell from Sacred Blacksmith, a very capable action girl who doesn't suit the role of a refined lady or princess as defined by her title.
DC Nation only ran 7 shorts of Amethyst making a full short cartoon episode length, the story is a reenactment of Amy's video game as she goes through many challenges shes already beaten with the game's original hero, before over coming the big boss Dark Opal which she had trouble with previously when playing the game.
Whether DC takes notice of this or not remains to be seen, but it would be a huge disappointment if this cartoon never saw a full series; from the footage we did get we saw something which could be on My Little Pony: Friendship is Magic levels of awesome and acceptance, something which all girls cartoon shows should aim for instead of trying to be Winx Club all the time.
