Wicked Witch of the West
The Wicked Witch appears as the main antagonist of the second half of Season Three of "Once Upon a Time" played by Rebecca Mader. This version goes by the name of Zelena (which means "green" in some Slavic languages). Zelena is discovered to be the daughter of the Queen of Hearts/the Miller's Daughter/Cora (Barbara Hershey/Rose McGowan), making her the older, long-lost half-sister of Regina the Evil Queen (Lana Parrilla). Zelena visited Rumplestiltskin (Robert Carlyle) and learned from him how to control her own powerful magic. Her storyline revolves around her efforts to create a time-travel spell that will allow her to go back and prevent the birth of Snow White's mother, Ava, who informed Prince Leopold (Cora's fiancé) that Cora was with child to sabotage Cora's attempts to infiltrate the royal family (before she can ruin Zelena's life, and thus Zelena would be raised as royalty. But despite Zelena's efforts to create the deadly time portal Emma Swan (supposedly the only wielder of light magic powerful enough to oppose her) her plans are halted when the Evil Queen masters light magic in time to oppose her (although her time-travel spell is completed, it takes effect after her presumed death, transporting Emma and Captain Hook (Colin O'Donoghue) back to before the original curse was cast). She was later thought to have been killed by Rumpelstiltskin.
Zelena (Once Upon a Time)
Time passes as Zelena grows into an adult. Zelena is reduced to helping her father and shaving her father. During one shave, she accidentally cuts him and uses magic to produce a cloth. This angers the woodcutter who declares that she is wicked and that he only looked after her because Zelena's 'mother' wanted the girl. He then reveals that Zelena is actually adopted to which she responds by walking out on him and going to ask the Wizard of Oz for help. Arriving at the Wizard's palace, she explains her situation to the great Wizard. She discovers that her birth mother was Cora and that Zelena was originally from the Enchanted Forest. At Zelena's request to visit this world, the Wizard supplies her with silver slippers that allows the wearer to visit any location so Zelena could find out more about her birth family. After meeting Rumplestiltskin, Zelena learns how to use her magic but also discovers that her younger sister, Regina is being taught magic and that she will cast a curse for Rumplestiltskin. Jealous, Zelena discovers that she isn't allowed to cast the curse so returns to Oz before Rumplestiltskin can get her silver slippers. Zelena goes to visit the Wizard so he could help her change the past. The Wizard refuses to help which only angers Zelena more. The young witch removes the Wizard's curtain and discovers that he is just a mortal named Walsh. She transforms him into an obedient flying monkey, before spying on Rumplestiltskin telling Regina that she is his greatest student. This causes Zelena to be jealous of her younger sister and her skin turns green with envy. "
