Medusa

Medusa is a character on ABC's Once Upon a Time. She débuts in the tenth episode of the third season. She is portrayed by CGI.

Medusa is based on a Gorgon with the same name from the Perseus myth from Greek mythology.

History
Medusa lives in a cavern near the old Summer Palace of the Enchanted Forest. She gains a notorious reputation as a creature who can turn anyone into stone if the person looks straight into her eyes. One day, she chases two intruders, Snow White and Prince Charming, after they purposely enter into her home. While Prince Charming goads Medusa into coming after him, Snow White hides in wait to cut off her head. Surprisingly, the sword has no effect on Medusa and she entraps Prince Charming, forcing him to meet her gaze, and thus transforming him into a stone statue. Medusa goes after Snow White next, but is tricked into meeting her own reflection and immobilizing herself into stone. From her own downfall, Prince Charming is freed.

Trivia
There are a few notable differences between Enchanted Forest Medusa and Greek Mythology Medusa
 * In Greek Mythology Medusa is the youngest of three sisters, her two older sisters Stheno and Euryale were immortal gorgons while she was infact mortal and thus only she could be killed out of the 3 gorgons, however in Fairy Tale Land, Medusa is an "only child" and is in fact immortal (at least from being killed by a beheading)
 * In the Greek Myth if you were to gaze upon Medusa and turn to stone there was no way to undo it, in Fairy Tale Land however, the only way to undo the "curse" is to kill Medusa.
 * Also in Greek Mythology, looking at Medusa's reflection via a mirrored shield would have no effect and you would not be a statue, in Fairy Tale Land however, looking at her reflection would be no less different than gazing upon her directly, as she was defeated by her own power.
