Cora

The cruel and controlling mother of Regina, Cora appears to have forgotten her humble origins, and the unwanted first born daughter that came with it, which she forsook when she formed a liaison with the powerful Rumplestiltskin in order to get access to magic and turn her life around. Her power got to her head, however, and Cora started going to extreme lengths to control her daughter's life, claiming it to be the best for her. Eventually, Regina pushed her through a looking glass and into Wonderland, where she became the notorious Queen of Hearts.
