"52 Shake-Up" is a series focusing on DC's New 52. Posts get a 52 Shake-Up tag if it's an already existing canon immigrant who now exists in the New 52 as well, or if it's a previously existing character who was changed so drastically by the New 52 to fit a version of themselves in another medium that they could be mistaken for being a canon immigrant.
You'd be forgiven for thinking that the archer named Artemis first appeared in Young Justice (2010), but she didn't. She actually first appeared all the way back in Infinity Inc #34 (December 1986) as a villain who was the daughter of Golden Age villains Tigress and Sportsmaster, just like Infinity Inc were the children and proteges of Golden Age heroes. In Young Justice she's likewise the daughter of Sportsmaster but trying to be a hero (or is a mole pretending to be a hero; it's been a while since I've seen the show)...at least until she becomes Tigress in season 2.
In the New 52, she makes two brief appearances. The first is in Teen Titans #8 (April 2012), where she's seen wearing a rugged version of her Young Justice outfit. She also has the blonde hair and long ponytail of her animated counterpart. She dies during "The Culling" crossover, but is later revealed to have been revived along with the rest of the teens "killed" during the Culling.
