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.
