A character shows up in the Teen Titans Annual named Artemis. She's blond, so I'm inclined to think it's the Artemis from the cartoon, but she's also wielding a homemade spear, calling Robin "boy," and acting quite a bit more like Artemis from the WW title.
She does also say that she was "pre-med" before ending up in whatever space those kids are for The Culling, so if she were an Amazon, that would mean she'd left the island or been exiled.
* an Artemis who was also an Amazon (from back in the 90's)
* Artemis, a villainess who was the daughter of the Golden Age villains Sportsmaster and Huntress, who was a member of Injustice Unlimited and fought against Infinity Inc. She later took the identity of Tigress.
* Artemis from Young Justice, who seems to be somewhat based on the the comic book character who eventually became Tigress.
* a character from mythology
