Emma (Supernatural)

Emma is a villainess appearing on the CW television series Supernatural.

She is portrayed by Alexia Fast, who previously appeared on the show as Missy Bender in "The Benders."

In "The Slice Girls," while working a case with his brother Sam, Dean Winchester goes to a bar and meets Lydia, a young woman. The two chat for a while before heading back to Lydia's house, where they spend the night having sex. The next morning, unknown to Dean, Lydia is heavily pregnant as a result of her tryst with the hunter.

It turns out that Lydia is an Amazon; Amazons are a race of monsters who mate with men to produce more of their kind. She quickly gives birth to her and Dean's daughter, whom she names "Emma." Emma quickly grows to a toddler within a matter of days, and Dean, for a while, remains unaware she is his daughter.

Lydia hands Emma over to the other Amazons to be trained. Emma quickly grows into a teenager and is initiated, then sent to kill her father as a rite of passage. She goes to Dean and reveals she's his daughter, falsely claiming she ran away from the other Amazons. When Emma draws a knife while his back is turned, Dean pulls a gun and aims it at her.

Sam barges into the hotel room and shoots Emma, killing her.
