Zelena

"The queen may be evil, but I'm wicked. And wicked always wins."

Zelena, also known as the Wicked Witch of the West, is a character on Once Upon a Time.

Season 3
After the return of the inhabitants of Storybrooke and their departure to the Dark Palace, Aurora warns her husband that they have to tell "her" that they've returned. Phillip says that "she" will be furious if she finds out, but Aurora reminds him that the woman would take it out on their child if she suspected they hid anything from her. Later, Regina and Snow are attacked by a Flying Monkey in the forest. Regina throws a fireball at the creature but it dodges the blast and grabs Regina. It tries to fly off with her but Snow grabs her ally and drags her back to the ground. Finally, the two women are saved by Robin Hood. When the group arrive at the Dark Palace, they are surprised to learn that it's surrounded by a protection spell - one that wasn't cast by Regina - meaning someone else is currently inside. Indeed, the flying monkey that attacked Regina arrives at the queen's castle and gives a drop of Regina's blood to his mistress. After doing so, the Wicked Witch of the West mixes the blood with a potion. Then, she smiles in triumph and says that she will finally get her revenge against Regina.
