Artemis is the Goddess of the Hunt, Forest, and the Moon. Timmy Turner meets her when he visits Mount Olympus, and she later joins her fellow Olympian Gods at a party at the Turner's house. She apparently loves bargain hunting, being the god of hunting.
Artemis was, in mythology, the daughter of Zeus. In her Fairly OddParents interpretation, however, they are siblings.
The voice of Artemis is wrongly attributed in the credits of the episode to Kevin Michael Richardson.
She probably has a twin brother Apollo
