Like Livewire, Harley Quinn and Renee Montoya before her, the Young Justice version of Artemis Crock made the transfer from a TV show to the actual DCU.
Although there was an Artemis Crock in DC comics prior to the DC Reboot, she was a (white) straight-up supervillain rather than the popular biracial superhero from the TV show…
…Unfortunately, what with her appearance being in Teen Titans, a comicbook with a ridiculously high turnover when it comes to killing off teenage characters (particularly in event comics), Artemis had the misfortune of turning up in the midst of the awful crossover event the Culling… where she promptly was killed off in the same issue she debuted.
Making you wonder why the heck they bothered to introduce the character in the first place if they were only going to kill her of… Oh wait, I remember why it was. It was to further inspire Tim Drake to defeat the bad guys, by having a girl he knew for like three pages get killed in front of him.
Also, that caption was retconned within months if this issue (stuff was editted out of the trade paperbacks so that it’d match), as they decided that Tim Drake was never Robin, and went straight to being Red Robin instead… because after the reboot, they realised that Bruce Wayne going through FOUR Robins in the space of only five years was kind of stupid, so Tim decided to name himself after a restaurant chain instead.
