Artemis was the daughter of the Titaness Leto and Zeus. After she was born she helped her mother deliver her twin brother Apollo. As Zeus' jealous wife Hera prohibited Leto from giving birth on solid group by mystically compelling all the interconnected lands to reject her, she took refuge and  had to deliver the twins on the floating island of Delos. To show her gratitude, Leto would later secure Delos with four pillars. The siblings soon discovered their natural talent for archery and, using arrows forged by Hephaestus, slew the Earth-serpent Python that Hera had sent to attack Leto.
Artemis and her brother later joined the Olympians on Olympus being worshipped by the humans of Ancient Greece.
Roman Empire (146 BC–324 AD)
Artemis was sent to abduct the Wasp from the small Caribbean island she was vacationing on. She attracted the Wasp's attention by transforming into a deer and drawing her into the undergrowth, before firing a magical arrow at her. The Wasp shot the arrow with a bio-electrical sting, vaporizing it, but the dust created knocked the Wasp out and Artemis took her to Olympus.
In New York City and on Olympus, Artemis clashed with the Avengers, and with several of her siblings (including her twin, Apollo) who had taken the Avengers' side against Zeus. Eventually Zeus came to his senses and called off his children, including Artemis. Artemis was subsequently in attendance when Zeus decreed that no Olympians would set foot on Earth again, though many of them have since done so.
Following the massacre of the Olympians by the hand of the vengeful goddess Nyx, Artemis resurfaced as part of the reborn pantheon. However, the Olympians were revived as savage warmongers who razed planets and took tribute in blood and treasure, regularly rotating in and out of reality aboard the floating city of New Olympus. The Guardians of the Galaxy clashed with the Olympians when they intercepted New Olympus in an attempt to stop the gods' rampage. They succeeded, but Star-Lord was stranded in the other side of reality alongside the Olympians.
During their encounter, Star-Lord had become entangled with the Olympians and their power was locked away in himself and his Element Gun. Star-Lord lived unaging in the otherdimensional world of Morinus for over a hundred years until enough uses of the Element Gun freed enough of the Olympians' power to enable their return. Star-Lord lured the Olympians away from Morinus, using the Gateway to return to his home dimension. The Olympians pursued him to reclaim their full power, and confronted him and the Guardians of the Galaxy on Daedalus 5. During their final battle, Artemis was killed by Gamora.
