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.
Kansas (Once Upon a Time)
It appears that Dorothy has won over the other witches, except for Zelena, who now has become more envious of this latest visitor to their world (as evidenced by her green skin returning), and as she watches from the well, Glinda comes over to talk to her. However, Zelena, having read the book of prophecies, believes that Dorothy will replace her, saying that she is the greatest evil and a threat to Oz. Later on, Zelena surprises Dorothy at the well, where Zelena's green skin returns, making her evil as ever and vows to threaten Dorothy by creating a fireball that she will aim at her. This prompts a confused Dorothy to take a bucket of water from the well and throw it at her, causing Zelena to melt. Dorothy then runs and tells Glinda what had happened, but Glinda tells her that what she did to Zelena was the right thing to do; it turns out that Zelena was the evil threat all along. Glinda then offers Dorothy a chance to join the council of witches, but Dorothy turns her down and says she's sorry and wants to go home. Glinda tells her that the Wizard (who she believes has returned to his normal form) will return her to Kansas.
