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)
Shortly after, Glinda, the Witch of the South, recruits Zelena into a sisterhood of witches. Along with the Witch of the East and the Witch of the North, the trio believe Zelena is destined to join them because of a prophecy foretelling of a sorceress arriving by cyclone and becoming the Witch of the West. Zelena is still obsessed about changing her past, but with Glinda's encouragement, she decides her own future as a good witch is more important. After receiving a pendant to harness her powers, Zelena views the western area of Oz, which she will be responsible for watching over. She and Glinda approach the wreckage from a cyclone to rescue a young girl named Dorothy. Fearing this child, who also arrived by cyclone, is the actual Witch of the West, Zelena researches the prophecy in the Book of Records, discovering that the sorceress will "unseat the greatest evil the realm has ever seen", which she believes is herself. Even with Glinda's advisement that her fears may be not true, Zelena plots to get rid of Dorothy by attacking the girl with fire. However, Dorothy counters her assailant with water, causing Zelena to physically melt away. Despite being seemingly dead, Zelena reemerges at the Wizard's Emerald City palace. Glinda offers Dorothy the opportunity to join the sisterhood, but she declines since she only wants to go home. Assuming the Wizard's voice, Zelena sends Dorothy back to Kansas with the silver slippers, and then reveals herself to a shocked Glinda. Zelena reaffirms her goal of changing her own past, and to keep Glinda from finding another sorceress to fulfill the prophecy, she banishes the Witch of the South to the Enchanted Forest. "
