Veratrine

Veratrine is played by Becca De La Rosa. She is a secondary antagonist turned secondary protagonist in Mabel.

Season Three
Veratrine, orignally referred to as Anna's Doppleganger, is created by Luna Thorne to take Anna Limón's place in the world of the living, specifically going back to Anna's job at King's County Home Help. No one notices that she is not Anna except for Mabel Martin. Eventually, she arrives at the Martin house and tries to convince Mabel to fall in love for her, thus leaving Anna in the Underhill. It does not work, and Mabel kills her instead.

Season Four
Veratrine returns in the first episode of season four, now having named herself and gained some semblance of personhood. She wants to help the girls kill the King, who she believes made her, because she doesn't want to be her creator's property anymore; however, she eventually realizes her creator is Luna Thorne instead, and throws this plan away. She falls in love with Luna and helps the girls get into the King's ball; after the girls defeat the King, runs off with Luna. She has not appeared in any episodes since Temporal Snake.

Trivia

 * According to her creator, Mabel Martin, in a tumblr post, Veratrine is both [quoted directly from the post for ease of access / to as not to miswrite anything] "most certainly not cis" and meant to "explore [Mx. Martin's] conceptualization of [her] own womanhood through the lens of being mixed-race."
 * Following the above bullet, Veratrine is written by Mabel Martin; Luna Thorne, her 'opposite,' is thus presumably written by Becca De La Rosa.
 * Veratrine is only a few months old, and is often referred to as a child by Anna and Mabel. She insists on disliking them, though she seems to hold some fondness for them both ("I wouldn't have left the girls!" is a direct lines from her in episode 32, and she goes to Anna and Mabel for comfort when she needs it, even over Luna).
 * Vera's technical titles are "the god of self-regeneration" and "a god of black mud and creation."
 * She's made, at least partially, of oak, moss, mud, twigs, and a piece of Anna Limón.
